A method for assembling a rack-and-pinion steering gear may involve introducing a steering pinion into a housing opening of a steering gear housing such that a region of a narrowed portion of a pinion shaft is situated at a level of a rack to be inserted, introducing the rack into the housing opening of the steering gear housing such that the rack is pushed past the narrowed portion of the pinion shaft into a setpoint position, and moving the pinion shaft farther into the steering gear housing to an end position such that a toothing region of the rack enters into engagement with a toothing of the steering pinion.

Method for the simplified assembly of a rack-and-pinion steering box of a rack-and-pinion steering system

A rack and pinion steering system for a motor vehicle may include a pinion shaft that is connected to a steering shaft and has a steering pinion that is engaged with a rack mounted in a steering gear housing such that the rack can be displaced along a longitudinal axis for pivoting steerable wheels. The steering shaft, the pinion shaft with the steering pinion, and the step-down gear mechanism may be received in the steering gear housing. The rack and pinion steering system may further include an electric motor that drives the pinion shaft via a step-down gear mechanism. The step-down gear mechanism may be arranged at an end of the pinion shaft that is remote from the steering shaft.
