A simple approximation to perfect Ackermann steering geometry may be generated by moving the steering pivot points [clarification needed] inward so as to lie on a line drawn between the steering kingpins, which is the pivot point, and the centre of the rear axle. [2]
Other than the motor, other parts of a complete direct-drive wheelbase include a rotary encoder (the position sensor), a controller board (that translate the FFB data from the game into steering wheel forces), and a motor driver board (servo drive), which fits into a slot of the controller board, and that controls the position, velocity and ...
Caster displacement moves the steering axis ahead of the axis of wheel rotation, as with the front wheels of a shopping cart. Caster angle moves the steering axis from vertical. [3] In automobile racing, the caster angle may be adjusted to optimize handling characteristics for a particular venue. This is all connected to the front wheels.
Swing axle suspension characteristics: Camber change on bumps, "jacking" on rebound. A swing axle is a simple type of independent suspension designed and patented by Edmund Rumpler in 1903 for the rear axle of rear wheel drive vehicles. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow ...
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. The resulting fault if alignment is not achieved within the demanded specifications is shaft misalignment, which may be offset or angular. Faults can lead to premature wear and damage to systems.
In some four-wheel drive vehicles there is a gear lever that engages a low-ratio gearbox. Other levers may switch between two- and four-wheel drive and differential locks. Some cars have a freewheel that disengages the driveshaft from the driven shaft. This happens when the driven shaft rotates faster than the driveshaft.
A drive shaft system weighs more than a chain system, usually 0.5–1 kg (1–2 lb) heavier. Many of the advantages claimed by drive shaft's proponents can be achieved on a chain-driven bicycle, such as covering the chain and sprockets. Use of lightweight derailleur gears with a high number of ratios is impossible, although hub gears can be used.
