A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
Rack and pinion unit mounted in the cockpit of an Ariel Atom sports car chassis, atypical of contemporary production automobiles Non-assisted steering box of a motor vehicle. Many modern cars have a steering mechanism called a rack and pinion. The steering wheel turns a pinion gear, which moves a rack back and forth to steer the wheels.
A steering linkage is the part of an automotive steering system that connects to the front wheels. [1]The steering linkage which connects the steering gearbox to the front wheels consists of a number of rods.
The steering pivot points [clarification needed] are joined by a rigid bar called the tie rod, which can also be part of the steering mechanism, in the form of a rack and pinion for instance. With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point.
The arrangements for adjusting the toe angle are not changed by introducing ball joints in the suspension, although the steering linkage itself must use 4 or more pivots, also usually ball joints, and in almost every vehicle ever made, some of these have been adjustable by having a threaded end and locknut, to enable the toe to be set precisely.
By moving the screw shaft, the nut rotates. Wheel and axle: Hoist, winch, rack and pinion, chain drive, belt drive, rigid chain and rigid belt actuators operate on the principle of the wheel and axle. By rotating a wheel/axle (e.g. drum, gear, pulley or shaft) a linear member (e.g. cable, rack, chain or belt) moves. By moving the linear member ...

For both ends of the car this would include the type of spring, location of the spring, and location of the shock absorbers. For the front suspension the following need to be considered The type of suspension (MacPherson strut or double wishbone suspension) Type of steering actuator (rack and pinion or recirculating ball)
