There are usually four camera units in a wheel alignment system (a camera unit for each wheel). The camera units communicate their physical positioning with respect to other camera units to a central computer, which calculates and displays. [3] Often with alignment equipment, these "heads" can be a large precision reflector.
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 ...
Ackermann geometry. The Ackermann steering geometry (also called Ackermann's steering trapezium) [1] is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
Cost based pricing is still a useful method for specific categories of service parts. Low volume parts sold once in a product-lifetime have little effect on profitability but do need a price in the market. Such parts can be priced using the cost based approach with slight markups on the cost of the parts.
The two wheels may be individually aligned, allowing for independent camber (vertical) and track (horizontal) alignment. Disadvantages: A pair of CV or universal joints is required for each wheel, adding complexity, cost, and weight. [2]
The wheel rate is calculated by taking the square of the ratio (0.5625) times the spring rate, thus obtaining 281.25 lbs/inch (49.25 N/mm). The ratio is squared because it has two effects on the wheel rate: it applies to both the force and the distance traveled. Wheel rate on independent suspension is fairly straightforward.
