ELECTRIC SERVO-ASSISTED STEERING SYSTEM FOR MOTOR VEHICLES

摘要

An electric servo-assisted steering system for motor vehicles comprising a worm gear (1) is actively connected to a drive shaft (9) of an electric drive motor (10). The worm (3) is radially stressed by a pre-tensioning device (12), whereby the pre-tensioning device (12) is provided in the form of a hydraulic pressure device (12). The drive shaft (9) can be connected to the worm (3) by means of a coupling (8), and the worm (3) is supported in this area via a pivotal bearing (5).
