Get a QuoteRack-and-Pinion Steering System At the heart of the rack-and-pinion system is the steering gear. As noted in the introduction, the pinion transmits rotary motion to the rack, which converts this movement into linear, side-to-side motion. Below, you can see the fundamental operation of a rack-and-pinion. The rack is mounted to the sub-frame (or

The gear train efficiency is calculated stage by stage. It depends on the type of gear train, geometry of the teeth as well as the coefficients of friction for the materials used for the gears. This calculation only takes into account losses on the friction between the flanks of the teeth. It does not include other losses such as bearings.

Steering is a system of components, linkages, etc. that allows a vehicle to follow a desired course. An exception is the case of rail transport, by which rail tracks combined with railroad switches (also known as 'points' in British English) provide the steering function. The primary purpose of the steering system is to allow the driver to guide the vehicle.
