Power steering assembly with targeted and adjustable compensation of road-side shock impulses to the steering gear, as well as a method for setting up a power steering assembly.

Abstract

The present invention relates to a power steering assembly for an electromechanical power steering system of motor vehicles (10), in particular utility vehicles, said assembly comprising a steering gear (1), the steering gear (1) being designed to transmit a rotational movement (III) introduced by a steering element, in particular by a steering wheel (15), via an input side (2) of the steering gear (1), in particular via an input shaft (3) of the steering gear (1), to an output side (4) of the steering gear (1), and the power steering assembly being designed to convert a movement (I) derived from the output side (4) of the steering gear (1) into a rotational movement (V) of at least one wheel (17; 19) of the motor vehicle (10) about a steering axis (18). According to the invention, an adjustable absorption unit (23) is provided for at least partially absorbing roadside shocks which have been absorbed via the wheel (17; 19) of the motor vehicle (10), and furthermore a separate preloading unit (24) is provided. The separate preloading unit (24) is designed to interact with the adjustable absorption unit (23) in such a manner that a predetermined preloading force is exerted onto the adjustable absorption unit (23). The invention also relates to a method for designing a power steering assembly for an electromechanical power steering system of motor vehicles (10).
