In INTERNAL COMBUSTION ENGINES the reversed principle of a slider-crank mechanism is used. This causes the conversion of the rectilinear translation of the piston into a rotation of the crank shaft, and thus of the wheels.
The STEERING GEAR OF A CAR is made of a worm gear. The power is transmitted from the steering wheel on the steering column to the steering gear, and from there to the steering rod on the steering levers on the steering knuckles.
In the INDEPENDENT WHEEL SUSPENSION of a car, the principle of the triangular control arm is used. The wheel suspension enables the suspension of the vehicle and allows steering, drive and braking movement.
