Wheel suspension for a rear wheel of a two-track motor vehicle

摘要

A wheel suspension for a rear wheel of a two-track motor vehicle, includes a five-link assembly which has five individual links which are coupled to the vehicle body via body-side bearings and to the wheel carrier of the rear wheel via wheel-carrier-side bearings, which five-link assembly, as viewed in the direction of travel, has a front pair of links and a rear pair of links, wherein the front pair of links has a lower, front link, with respect to the axis of rotation of the wheel, and an upper, front link, and the rear pair of links has a lower, rear link, in particular track rod, and an upper, rear link. A lower spring link, on which a spring arrangement having a vibration damper and a supporting spring is supported, is arranged in the direction of travel between the front and rear pairs of links. The front pair of links with respect to the spring link is of softer design in the transverse direction of the vehicle than the rear pair of links. As a result, a change in the toe-in at the rear wheel takes place under exertion of a lateral force or a longitudinal force.

主权项

1. A wheel suspension for a rear wheel of a two-track motor vehicle, comprising:
a five-link assembly comprising five individual links pivotally coupled to the vehicle body and to a wheel carrier of the rear wheel via respective bearings on the vehicle body and the wheel-carrier, wherein two of the five individual links form a front pair of links with respect to a direction of travel of the motor vehicle, and another two of the five individual links form a rear pair of links with respect to the direction of travel, said front pair of links, with respect to a rotational axis of the wheel, having a lower front link and an upper front link, said rear pair of links, with respect to the rotational axis of the wheel, having a lower rear link and an upper rear link, wherein a further one of the five individual links is configured as a lower spring link and is arranged in the direction of travel between the front and rear pairs of links; a spring arrangement supported on the lower spring link, said spring arrangement comprising a vibration damper and a suspension spring, wherein the front pair of links is configured softer in transverse direction of the motor vehicle than the rear pair of links so that a toe-in change results at the rear wheel in response to a lateral force and a longitudinal force acting on the wheel suspension; and a stabilizer, said stabilizer having a pivotally supported middle section oriented in transverse direction of the vehicle and at least one output leg extending from the middle section in longitudinal direction of the vehicle, said output leg being directly or indirectly pivotally connected to one of the five individual links via a substantially vertically extending rod.
