Both tracks and wheels were used for steering. The steering system was set up so that gentle turns used just the steerable front wheels, but brakes would be applied to the tracks the farther the steering wheel was turned. The Sd.Kfz. 250 also inherited the track-sparing but more complicated rollers in place of the more commonplace toothed ...
On a bicycle wheel, the rim is clearly just one component of the assembly, and it can be purchased separately and replaced if damaged or if the sidewalls have been eroded by rim brakes. [17] In discussions of automobiles, however, the terms wheel and rim are often incorrectly used synonymously, as in decorative wheels being called rims. One ...
A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
The 2008 model year xB is 2.8-inch (71 mm) wider, 12-inch (300 mm) longer - including 4-inch (100 mm) longer wheel to wheel - and 600 pounds (270 kg) heavier than the first-generation xB. The first-generation Scion xB (being a rebadge of the original Toyota bB) was based on the Yaris platform, but the second-generation xB was based on the new ...
Thus, the weight of the vehicle tends to rotate the wheel about the kingpin back to this position. The kingpin inclination also contributes to the scrub radius of the steered wheel, the distance between the centre of the tyre contact patch and where the kingpin axis intersects the ground. If these points coincide, the scrub radius is zero.

The point where the steering axis line contacts the road is the fulcrum pivot point on which the tire is turned. Scrub radius is changed whenever there is a change in wheel offset. For example, when the wheels are pushed out from the body of the car the scrub radius becomes more positive.
