Embodiment Construction

[0021] exist figure 1 An exemplary embodiment of a steering system 1 according to the invention with a pivot bearing 6 according to the invention is shown in . The steering system has a worm gear set 2 with which the steering torque is transmitted from a worm shaft 4 to a worm gear 3 . For this purpose, a toothing element 7 is formed on the worm wheel 3 , which meshes with a toothing part 8 of the worm shaft 4 . The worm shaft 4 is mounted rotatably at at least one bearing point 5 , preferably at least two bearing points 5 , in the housing of the worm gear set 2 . The steering system 1 is preferably designed as an electrically assisted steering system 1 . To this end, the steering system 1 includes an electric steering assistance system 9 with which the driver's steering force is supported for changing the steering angle. According to the invention, the worm shaft 5 is mounted on the drive side by means of a pivot bearing 6 . On the side facing away from the drive side, th...

Abstract

The invention relates to a steering system for a motor vehicle (1) having a worm gear set (2), comprising a worm wheel (3) and a worm screw (4), the worm screw (4) being mounted rotatably in a housing of the worm gear set (2) by means of a pivot bearing (6) at at least one bearing point (5). According to the invention, the pivot bearing (6) has a higher load capacity than a pivot bearing with a single-row standard grooved ball bearing. The invention further relates to a pivot bearing (6) for a steering system (1), having an inner race (11) and an outer race (12), a plurality of rolling elements (17) being arranged between the inner race (11) and the outer race (12). According to the invention, one of the bearing races (11, 12) is designed as a solid race and the respective other bearing race (11, 12) is designed as a split bearing race (21), wherein the split bearing race (21) comprises a first race element (22) and a second race element (23).

Description

technical field [0001] The invention relates to a steering system for a motor vehicle with a pivot bearing according to the preamble of the independent claim. Background technique [0002] In modern motor vehicles, the steering system is used to reduce the steering force during a steering movement by the driver by means of a corresponding steering force assist. This can be done in a known manner with hydraulic servo assisted steering or with electrically assisted or electrohydraulic assisted steering forces. In addition, steering systems are known which generate steering torque on the vehicle side to inform the driver of the motor vehicle of a recommended steering movement. In electrically assisted steering systems, an electric drive motor is generally used, which acts on the steering shaft via a worm gear set in order to generate a correspondingly high steering torque for turning the wheels. [0003] Solutions are known from the prior art in which the worm shaft is mounte...
