Wheel suspension system for motor vehicles

Abstract

The invention relates to a wheel suspension system for motor vehicles, having a wheel carrier (3) which has an axle-side carrying element (19) and a wheel-side carrying element (17) which mounts a vehicle wheel (1) rotatably, between which carrying elements (19, 17) an actuator (21) is connected, upon the actuation of which the wheel-side carrying element (17) can be pivoted by a pivoting angle (f) with respect to the axle-side carrying element (19) in order to set a trail angle and / or camber angle (d, e). According to the invention, the actuator (21) has a wheel-side rotational part (23) and an axle-side rotational part (25) which can be rotated with respect to one another about their rotational axes (27, 28), and the wheel-side rotational part (23) can be deflected by the pivoting angle (f) with respect to the axle-side rotational part (25) when the two rotational parts (23, 25) are rotated.

Description

technical field The invention relates to a wheel suspension arrangement for a motor vehicle according to the preamble of claim 1 . Background technique In an active steering system, especially for the rear axle of a vehicle, the camber or track can be adjusted via an actuator / control unit, so that the driving characteristics of the motor vehicle can be actively influenced by controlling the actuator. A wheel suspension arrangement of the mentioned type for a motor vehicle is known from DE 3928135 A1. The wheel hub bracket of the wheel suspension structure has a wheel-side support for rotatably supporting the wheel and an axle-side support, and an actuator is connected between the two supports. In this case, the actuator is a hydraulic adjusting cylinder, which is supported on the one side on the bearing bracket of the wheel carrier and on the other side is pressed by its piston rod against the rolling bearing outer race of the wheel bearing , whereby the wheel bearings to...

AI Technical Summary

Problems solved by technology

The actuator arrangement known from DE 3928135 A1 between the bearing bracket and the wheel bearing is costly and heavy in terms of structural compactness and design

The high overall weight of the wheel suspension is particularly disadvantageous, since the hub brackets involve masses that are not supported on springs
