Steering aid driving mechanism for a motor vehicle's steering device has a motor to drive a motor shaft coupled to a rotary transfer element for driving movement

摘要

Held in a casing for a steering aid driving mechanism, a rotary transfer element (6) links to a driven shaft (8) for driving movement. Designed as a multi-, preferably two-stage toothed-belt gearing, a toothed-belt gearing links between a motor shaft (4) and the rotary transfer element and between the rotary transfer element and the driven shaft. Fitted concentrically to an intermediate axle (5), a means of retention holds the rotary transfer element and has a controllable fixing element on the outer side of the casing.
