Abstract
A wheel suspension for motor vehicles includes at least one upper control arm, in particular an upper transverse control arm, and at least one lower control arm, in particular a lower transverse control arm, which are hinged on the body of the motor vehicle suspension on the one hand, and on the other hand are connected to a wheel carrier, thus forming a preferred, substantially vertical steering axle. At least one suspension spring and at least one shock absorber are provided. The at least one suspension spring and/or the at least one shock absorber are designed to be rotatable.
Claims23
A wheel suspension for a motor vehicle, comprising:
- at least one upper control arm and at least one lower control arm, wherein the at least one upper control arm and the at least one lower control arm are articulated on a body of the motor vehicle and connected to a wheel carrier to form a substantially vertical steering axis, and
- at least one bearing spring formed by at least one first torsion bar and at least one shock absorber, with at least one of the at least one bearing spring and the at least one shock absorber constructed for rotation, and
- wherein the at least one first torsion bar is drivingly coupled with the lower control arm and passes through a rotation damper of the at least one shock absorber.
A wheel suspension for a motor vehicle, comprising:
- at least one upper control arm and at least one lower control arm, wherein the at least one upper control arm and the at least one lower control arm are articulated on a body of the motor vehicle and connected to a wheel carrier to form a substantially vertical steering axis,
- at least one bearing spring formed by at least one first torsion bar and at least one shock absorber, with at least one of the at least one bearing spring and the at least one shock absorber constructed for rotation, and
- at least one additional torsion bar engaging on the lower control arm, wherein a spring pretension of the at least one additional torsion bar is adjustable with an electric-motor-driven rotation actuator.
A wheel suspension for a motor vehicle, comprising:
- at least one upper control arm and at least one lower control arm, wherein the at least one upper control arm and the at least one lower control arm are articulated on a body of the motor vehicle and connected to a wheel carrier to form a substantially vertical steering axis, and
- at least one bearing spring and at least one shock absorber, wherein the at least one bearing spring or the at least one shock absorber, or both, are constructed for rotation,
- wherein the upper control arm is articulated on the body of the motor vehicle by an electric-motor-driven actuator for adjusting at least one of camber and caster.
A wheel suspension for a motor vehicle, comprising:
- at least one upper control arm and at least one lower control arm, wherein the at least one upper control arm and the at least one lower control arm are articulated on a body of the motor vehicle and connected to a wheel carrier to form a substantially vertical steering axis,
- at least one bearing spring and at least one shock absorber, wherein the at least one bearing spring or the at least one shock absorber, or both, are constructed for rotation,
- a tracking control arm operating on a control arm of the wheel carrier, said tracking control arm being articulated on the body, either non-adjustable or adjustable via a steering device, and a control arm actuator for adjusting a length of the tracking control arm.
A wheel suspension for a motor vehicle, comprising:
- at least one upper control arm and at least one lower control arm, wherein the at least one upper control arm and the at least one lower control arm are articulated on a body of the motor vehicle and connected to a wheel carrier to form a substantially vertical steering axis, and
- at least one bearing spring and at least one shock absorber, wherein the at least one bearing spring or the at least one shock absorber, or both, are constructed for rotation,
- a single-sided or one-piece modular frame connected with the body of the motor vehicle via passive or active decoupling elements and configured for mounting at least one element selected from the at least one upper control arm, the at least one lower control arm, at least one tracking control arm, the at least one shock absorber, a rotation actuator for a torsion bar, an actuator for the at least one upper control arm and a control arm actuator for the at least one tracking control arm.
