A subframe for motor vehicles, in particular for the front axles of passenger cars, which includes side parts running in the longitudinal vehicle direction that are joined by upper and lower cross elements running in the transverse vehicle direction to form a box profiled section, which is deformable in the longitudinal direction in response to longitudinal forces produced by a collision, and which is able to be used as an assembly unit.

Subframe for motor vehicles

A hydraulic support in the form of a hydraulically damped elastomer support is disclosed. The hydraulic chambers of the support are arranged and designed in such a way that effective damping is achieved both in the case of vibrations in the longitudinal direction and vibrations in the transverse direction and that all the chambers can contribute to dynamic support in the transverse direction.

Hydraulic support

A front axle of a motor vehicle has steerable wheels and is equipped with a torsion-bar stabilizer to improve the returnability of the steering without a large amount of additional technical expenditure. Connecting arms connect the wheel carriers to the offset ends of the torsion-bar stabilizer with the joint of the connecting arms which is on the wheel-carrier side articulated in the respective steering axis on the wheel carrier. During movement of the wheel carriers about the steering axis, the connecting arms can be swivelled via the wheel carriers, in the same direction as the wheel carriers and counter to a flexible restoring support situated in the connection of the torsion-bar stabilizer to the respective connecting arm. The restoring support between connecting arms and torsion-bar end pieces provided by a rubber torsion bearing produces a restoring torque which is proportional to the steering angle and improves the returnability of the steering.
