The rover's Mars Descent Imager camera also caught images of wind erasing its wheel-track in the fine soil.

Called the "Reconfigurable Wheel Track" (RWT), it starts off round and uses a thin rubber cover over a robotic wheel.

One of the innovations, a reconfigurable wheel-track, comes out of Carnegie Mellon University's National Robotics Engineering Center in partnership with DARPA.

The wheel-track is just one of a handful of designs meant to improve survivability of combat vehicles beyond just up-armoring them.

However, there was a stretch of shore, across the lake, that offered a bit of a lee, so our party of anglers snaked our way there along a four-wheel track.
|
|
As you can see in the video, the reconfigurable wheel-track demonstrates a seamless transition between a round wheel shape and a triangular track in about two seconds, and the shift between its two modes can be executed while the vehicle is in motion without cutting speed.

The steps are linked by a continuous metal chain that forms a closed loop. The front and back edges of the steps each have two wheels, the rear of which are set further apart and fit into the trailer-wheel track while the front set have narrower axles and fit the step-wheel track.
|
|
With implements mostly contained within its wheel track, part width operations, for example ploughing or root crop harvesting, are perfectly feasible, whereas with existing tractor systems they are not.
|
|
The track system is built into the truss to guide the step chain, which continuously pulls the steps from the bottom platform and back to the top in an endless loop. One track guides the front wheels of the steps (called the step-wheel track) and another guides the back wheels of the steps (called the trailer-wheel track). The relative positions of these tracks cause the steps to form a staircase as they move out from under the comb plate. Along the straight section of the truss the tracks are at their maximum distance apart.

The Railsbach was an automobile built in Saginaw, Michigan by L.M. Railsbach in 1914. The company classed the vehicle as a light car, but with its wheel track of 3 ft, it would make it a cyclecar. The two-seater sold for $350. It had a water-cooled 4-cylinder, 1.2L engine.

Softer landing trailing link main landing gear reduced fuel tank capacity to 5,440 pounds, 360 pounds less than the Ultra's, but it has more range. The wheel track was narrowed 3.7 feet for better ground tracking and easier crosswind landing. The wing leading edge is de-iced by Bleed air. Boundary layer energizers and a stall fence improve stall characteristics.

About 50 similar Mercury Cyclones were also produced by Ford in 1964, destined to be modified to represent Ford in A/FX competition, which they dominated, as well. These vehicles varied greatly in wheel track due to customer options for varying suspension and wheel/tire combinations. Front tracks from 54 to 56 in and rear tracks from 53.5 to 55.5 in were common.

At the rear the tail was conventional, with a near-triangular fin and deep, rounded rudder and a tailplane mounted near the top of the fuselage. The elevators had a cut-out for rudder movement. The SF-1's landing gear had independent legs with their struts enclosed in streamlined fairings and braced with streamlined tie-rods. Wheel track was .

With an overall width of , it was narrower, yet the wheel track was nearly identical. Shipping weight, approximately with the straight six-cylinder engine, was also similar to the Falcon. A fully equipped V8 model weighed approximately . Although most of the mechanical parts were from the Falcon, the Mustang's body was completely different; sporting a shorter wheelbase, wider track, lower seating position, and lower overall height.

KH50 Vollmer subsequently moved to Czechoslovakia, to join the Skoda company for whom he designed a wheel/track light tank, the KH-50 (Kolo-Housenka). This design had roadwheels mounted on the drive sprockets and jockey wheels behind them to support the tracks. Despite impressive specifications for the period - 13 mm armour, 37 mm turret- mounted armament, and a 50 hp engine capable of driving the tank at (on tracks) and (on wheels) - it was rejected by the Czech army. The army was, however, impressed by the hybrid wheel/track concept and commissioned further studies, which resulted in the KH-60 (1928–29) and the KH-70 (1930). In these two designs the engine power was increased to 60 hp and 70 hp respectively and a better system was developed for switching between track and wheel use which allowed a change in less than 10 minutes.

Velomobiles with fairings that are mainly for weather protection can use a more upright seating position. This tends to improve both the ability to see and be seen. However, to retain stability against tipping (both cornering and cross-winds), the wheel track needs to be wider than a comparable velomobile with a low seating position. In turn, this may make the velomobile quite a bit wider than a conventional cycle.

Dating back to the 1940s, chopping and channeling was a popular method of modifying a car's aerodynamics. Increasing the wheel track width through spacers and wide body kits, or lowering the center of gravity via suspension modifications, can enhance the car's cornering ability. Often, suspension tuners unfamiliar with spring dynamics will cut stock springs, producing a harder, bouncy ride. It is also common to stance a car, lowering it beyond its optimal ride height purely for appearance.
|
|
The chassis design was as new as the bodies with a wider wheel track, front and rear. The left wheel was adjusted to have slightly more positive camber than the right, which resulted in a more uniform and stable steering feel on high-crown road surfaces while maintaining excellent freeway cruise stability. Clearances for spring travel were also improved for a smoother ride over all types of surfaces; the coil springs at each wheel were computer-selected to match the individual car's weight.

Continue as far up the two wheel track road as your vehicle will take you. There are no trails so you must determine your own best route up the mountain. It will be immediately apparent that any direct route to the window is a very difficult task, even dangerous. Instead, make your way up to Hole in the Mountain Peak, located a short distance to the north and an easier climb, and then make the approach to the window from the west side of the mountain.

For ground use the front wheel is powered by pedals via a short chain and a Nexus 7-speed hub transmission and can be adjusted to accommodate pilots from in height. Road gearing is standard equipment, with mountain gearing optional. An optional telescoping rear axle allows a narrow wheel track for road use and a wider one for take-off and landing to increase stability and reduce the risk of roll-overs. Optional equipment includes wheel fenders, head and tail light mounts and a ballistic parachute.

The designers chose to emphasize the length of the hood this year, which meant that the redesigned front end grew by three inches. However, the new rear end was four inches (102 mm) shorter. Improvements to the suspension were promoted as the new "Torsion-Quiet" system, which used strategically placed rubber isolators to reduce road noise and vibrations. The rear wheel track was broadened by nearly three inches as Dodge installed the rear axle that had been used only on Wagons on all 1970 Monaco models.

Since the vehicle was – like the cavalry – expected to drive as much or more on the roads as off, the design featured a wheel-track layout capable of both modes. Given the limitations of that era, it was expected the tires would have greater durability over roads than the tracks themselves. The US Army had already tested and dismissed Christie’s all-steel road-wheel design. In order to avoid that failure, the Combat Car was designed using three big road-wheels with rubber tires that also served as rollers.

Top Attractions include various art galleries, a giant sundial at the municipal offices, and an Ox Wagon monument (Kakebeenwa) to commemorate the Ossewa Trek of 1838. The ox wagon monument has an impression of a wagon wheel track made in concrete to commemorate the exodus of dissident Afrikaners from the Western Cape. In the past, Napier's main craftsmen were blacksmiths, a heritage which is commemorated by annual festivals. Other annual events are the Patatfees (Sweet Potato Festival), every June, and the "Voet van Afrika" (Foot of Africa) Marathon which is run in mid-September.

Two separate hydraulic systems, one being power- operated and the other hand-operated, are present for the deployment and retraction of the undercarriage; in the event of both failing, pilots can release the retaining catches holding the undercarriage in place, deploying the wheels to the 'down' position using weight alone. A wide wheel-track was used to allow for considerable stability during ground movements and to enable tight turns to be performed.Flight 12 May 1938, pp. 471–472. The prototype and early production Hurricanes were fitted with a Watts two-bladed fixed-pitch wooden propeller.

Split friction may be caused by an improper road spot repair that results in high variance of texture and colour (thin ice on newly paved black spots thaws faster than ice on old greyish asphalt) across the road section. To some extent, the risk for split friction can be measured with a road profilograph, scanning the pavement texture in both the left and right wheel paths. A full analysis of the split friction issue requires a friction device that measures both the left and right wheel track at the same time. The ViaFriction skid device can be used for such a purpose.

Audi RS6 Avant quattro (C6) The C6 RS 6 Avant was launched in April 2008, and the four-door saloon/sedan was available from August 2008. Constructed from steel in a monocoque (unibody) design, the RS 6 uses lightweight aluminium for its front wings (fenders) and bonnet (hood). Visually, the RS 6 differed from the related S6, having flared front and rear wheel arches (fenders), harking back to the original Audi Quattro, to allow for a wider wheel track. It also had no front fog lights to allow for larger frontal air intakes (for the two side-mounted intercoolers (SMICs), and additional radiators).

Corrado (rear) The Corrado's floorpan is based on the A2 platform (i.e. Mark 2 Golf/Jetta) and, with the exception of VR6 models, all versions use the subframes, suspension, steering and braking components from the Volkswagen A2 platform model range. The VR6 uses suspension components from the A3 model range, including the rear axle assembly and some parts of the A3's 'plus' type front axle assembly. The subsequent wider front wheel track of the Corrado VR6 necessitated the fitting of new front wings with wider wheel arches and liners along with a new front bumper assembly.

Pilot's views on J 22 Retrieved: 22 June 2008 With 575 km/h (360 mph) from a 795 kW (1,065 hp) engine, the press called the diminutive fighter "World's fastest in relation to the engine power" (while not absolutely true, it was in the same class as the early marks of Supermarine Spitfire and Zero).Comparison with fighters 1,000 to 1,1150 hp Retrieved: 22 June 2008 The J 22 crews promptly modified this to "World's fastest in relation to the track width" (for which the Spitfire might also have competed), because of the very narrow wheel track. The aircraft was retired in 1952.

In these two designs the engine power was increased to 60 hp and 70 hp respectively and a better system was developed for switching between track and wheel use which allowed a change in less than 10 minutes. Two KH-50 prototypes were built, one of which was later converted to a KH-60; the other was scrapped. Actual production included two KH-60s to the USSR and a KH-70 to Italy.

One of the reasons for the comparatively low retail price of the Great Wall Haval H3 is that it is based heavily on older models by other manufacturers. The entry-level engine is the 4G64 2.4 litre gasoline inline-four supplied by Mitsubishi, the exterior resembles the Isuzu Axiom and the chassis is also Isuzu similar if not the same as the Isuzu MU, contrary to media reports that it was a Toyota 4Runner Chassis. The Haval H3 has a wheelbase of and a wheel track of . The Haval H3 is a sport utility vehicle, with selectable rear- wheel-drive or four-wheel drive.

In addition to the new roofline, front and rear ends looked markedly different this year as 1973 was the year of the federally mandated front bumper, adding to the car's length. Additional new body features were an acoustical double- panel roof, tighter-fitting glass and flush style outside door handles. Wheelbase dimensions were retained; a sporty for coupes and for sedans and station wagons, but bodies were five inches (127 mm) longer and an inch wider with a wider wheel track. The station wagon, available in 6 or 9 passenger seating, featured a new counterbalanced liftgate which allowed for easier entry and loading up to 85 cubic feet.

Stairclimber wheels A stairclimber is a type of trolley fitted with rotating wheels or tracks so that it can be pushed or pulled up or down steps or a stairway. Stairclimbers can be manual or battery-powered, and are commonly found in wheel, track, push arm or walker variants. Powered electric stair climbers are available in many variants, both in manufacture and mechanical operation, with the most common being push arm and walker variants due to size, speed and mobility. Tracked versions offer the greatest S.W.L (safe working limit) with regards to the load being moved, whilst push arm and walker variants offer greater speed and ease of operation.

Initially, Christie promised to sell his M1928 tank design to the Polish government. In 1929, Captain Marian Rucinski of the Polish Military Institute of Engineering Research (WIBI) was sent to the US, and soon learned of the M1928 tank being constructed by Christie's company, the US Wheel Track Layer Corporation in Linden, New Jersey. Rucinski also learned of a design for an improved tank (later known as the Christie M1931) that had recently gone to blueprint. Rucinski's opinion was so enthusiastic that on February 16, 1930 a special acquisition commission was dispatched to the US, headed by the Chief of the Engineering Department, Colonel Tadeusz Kossakowski. The commission signed a contract with Christie in March for construction and delivery of a single M1928 tank, and paid a pre-payment to him.

The rear wheel track was some narrower than the front track and looked peculiar from behind, a feature that was blamed (probably incorrectly) for excessive understeer at low speed. It was reported to be better balanced at higher speeds - indeed, the narrower track was deemed to assist high speed straight-line stability and was a feature incorporated in many record-breaking cars of pre and post-War design. Nevertheless, it is probable that the narrower rear track was occasioned by the lack of a suitably dimensioned component from Salisbury, the axle manufacturer. 2.4 Litre with new grille introduced 1957 1957 3.4 Litre automatic The interior was of similar design to the contemporary Jaguar saloons and sports cars, with most of the dials and switches being located on the central dashboard between the driver and passenger.

Although controlled traffic farming is still in its infancy as far as adoption is concerned (partially because the enabling technology of satellite guidance is still relatively new), there is a better engineering solution that would reduce tracked areas to less than 10%. This is not a recent concept, having been pioneered by Alexander Halkett in the 1850s and David Dowler in the 1970s, but the concept of a wide span vehicle is becoming increasingly attractive because of the other advantages it brings. The concept is described in detail at controlled traffic farming Europe's wide span page and achieves the low tracked area by virtue of using one of the same wheel tracks on adjacent passes. The system also reduces reliance on satellite technology because a guiding wheel track for the next pass is automatically laid down.

This "slowly drift to the right" scenario applies to jurisdictions with right-hand traffic, so in jurisdictions with left-hand traffic it would be a "slowly drift to the left" scenario. This phenomenon implies that a sleeping driver often does not react and begin to recover, until all four wheels have struck a rumble strip; if the paved shoulder is narrower than the width of the vehicle wheel track, a rumble strip may not prevent a sleeping driver from going off the road. On a single-lane highway, an overreacting driver has less room to regain control, which may exacerbate their initial overreaction after striking the strips, resulting in a roll-over or head-on collision. A crash investigating officer stated: "It's consistent with someone who falls asleep or overreacts to the rumble strips", which implied that this was not the first time the officer has witnessed this situation.

After World War I, the Polish army began designing tankettes, light tanks, and armored vehicles, many by Škoda. The German engineer Joseph Vollmer joined Škoda and designed a wheel/track light tank, the KH-50 (Kolo-Housenka). This design had roadwheels mounted on the drive sprockets and jockey wheels behind them to support the tracks. During World War I, Vollmer was chief designer for the German War Department's motor vehicle section, and he had designed the World War I German tanks A7V, K-Wagen, LK I and LK II. Despite the design for the KH-50 (Kolo-Housenka) having impressive specifications for the period - 13 mm armour, 37 mm turret-mounted armament, and a 50 hp engine capable of driving the tank at 8 miles per hour (13 km/h) (on tracks) and 22 miles per hour (35 km/h) (on wheels) - it was rejected by the Czech army.

Christie later reversed course and failed to deliver on his contract obligations, and faced with potential litigation, eventually returned the payment made by the Polish government, which never obtained the tank they had ordered.Magnuski, Janusz, Armor in Profile 1/Pancerne profile 1, Warsaw: Pelta (1997) trans. by Witold Kałużyński Though the Soviet Union had no diplomatic relations with the US at the time, and was barred from obtaining military equipment or weapons, Soviet OGPU agents at the trade front organization AMTORG managed to secure plans and specifications for the Christie M1928 tank chassis in 1930 using a series of deceptions. On April 28, 1930 Christie's company, the U.S. Wheel Track Layer Corporation, agreed to sell Amtorg two M1931 Christie-designed tanks at a total cost of $60,000 US, with the tanks to be delivered not later than four months from date of signing, together with spare parts to the purchased tanks for the sum of $4,000.
