What are the components of a steering gear?

[SanAliyah]

The components of a steering gear include the steering wheel, steering shaft, and steering column. The steering gear is a mechanism that converts the rotation of the steering wheel into the swinging motion of the pitman arm or the linear reciprocating motion of the rack shaft, while amplifying the steering force. The steering gear is usually fixed to the vehicle's frame or body, and the steering force typically changes its transmission direction after passing through the steering gear. Steering gears can be classified by their assistance type into mechanical (non-assisted) and power-assisted types. Mechanical steering gears can be further divided into rack-and-pinion, recirculating-ball, worm-and-roller, recirculating-ball-and-nut, and worm-and-sector types based on their structural design. Power-assisted steering gears are categorized into pneumatic and hydraulic types based on the energy transmission medium used.
