rack and pinion |
Also found in: Wikipedia | 0.03 sec. |
rack and pinionMechanical device consisting of a bar of rectangular cross section (the rack), having teeth on one side that mesh with teeth on a small gear (the pinion). If the pinion rotates about a fixed axis, the rack will move in a straight path. Some automobile steering mechanisms have rack-and-pinion drives that use this principle. If the rack is fixed and the pinion is carried in bearings on a table guided on tracks parallel to the rack, rotation of the pinion shaft will move the table parallel to the rack. On machine tools, this principle is used to obtain rapid movements of worktables. rack and pinion [′rak ən ′pin·yən] (mechanical engineering) A gear arrangement consisting of a toothed bar that meshes with a pinion.

| Speaking of the rack and pinion steering, the rack has a larger diameter than the previous model, and the steering feel is improved by using a bushing fitted with an internal cylinder to support the steering gear cross member. An improved rack and pinion steering and a new air suspension help accomplish these maneuvers with aplomb. With these new programs, which will utilize high-pressure vacuum diecasting methods, Contech will supply rack and pinion steering housings and steering column components for a truck program. |
