A steering column arrangement includes a steering spindle, which rotates about its longitudinal axis and serves to transfer a torque, generated by a steering wheel, to a steering gear, and a blocking device, which prevents the rotational motion of the steering spindle, especially in the event of a collision. The blocking device includes a stator, which is stationary in relation to the rotational motion of the steering spindle, and against which a blocking element is mounted in a relatively moveable manner. To prevent, in a reliable manner, an undesired twisting of the steering wheel, especially in the event of a collision, the blocking element is moveable into a locked position in a radial direction toward the steering spindle.

As a result of a configuration and position of an upper transverse link and of a lower transverse link, a wheel pivot axis is created which has a point of intersection with an area region of a vertical wheel central transverse plane and a wheel central longitudinal plane. An adjustment of the wheel in a toe-out sense takes place under the influence of braking forces and an adjustment of the wheel in a toe-in sense takes place under the influence of drive forces. Furthermore, as a result of different mount characteristics at the lower transverse link and at the track rod, it is ensured that, in the event of side forces, the wheel which is at the outside of the corner is adjusted in a toe-out sense.

Wheel suspension for a front axle of a motor vehicle

A wheel suspension for the rear wheels of a motor vehicle is created, with three links being provided in an upper link plane, and with a foremost link as viewed in the direction of travel being provided as a track rod and the two further links being provided as separate individual links at both sides of a vertical wheel central transverse plane. A triangular link is arranged in the lower link plane, which triangular link holds a spiral or air spring and a damper strut spaced apart from one another. By corresponding pole formations defined by the links, elastokinematic or imaginary pivot axes are formed, which permits an elastokinematic adjustment of the wheel in a toe-in sense under the influence of braking forces, side forces and load shift forces. The wheel suspension is also configured such that an elastokinematic adjustment of the wheel in a toe-out sense is obtained in the event of wheel loads and drive forces.

The subframe contains a framework which is cast as a single part and has profiled hollow members for the longitudinal and cross members. The cross members are connected to each other via supporting pillars at the corners, or are integrally formed on the supporting pillars. Arms which protrude outward are integrally formed on the supporting pillars or on the longitudinal and cross members, the end sides of which arms have connecting bearings toward the vehicle body. A differential is held on the two cross members, the differential having one mounting on the front cross member and two mountings on the rear cross member. The longitudinal members have a curved passage opening for the drive shafts of the differential. Mountings for wheel guiding links are arranged on the outside of the longitudinal member.

An axle support for a front axle of a motor vehicle, a stabilizer is disposed on the front side which can be fixed by holding elements. Each holding element is constructed for fastening the stabilizer and is simultaneously used as a so-called crash support which has a protective and energy-absorbing effect in the event of an impact.

A subframe for a motor vehicle, particularly for a rear axle of a motor vehicle, includes of a chassis frame which can be fastened to the vehicle body and which comprises at least cross members which are connected with side members. Bearings for suspension links are provided on the side members, and a transmission assembly is disposed in the chassis frame between the side members and the cross members. The side member structure of each side comprises in each case two members which are arranged above one another and which have a through-opening for axle shafts of the transmission assembly between one another and converge approximately at the end side and are connected with the cross members. By way of a three-point bearing, the transmission assembly is connected with the cross members and the side members, and the axle shafts of the assembly extend through the through-opening toward the wheel.

An arrangement for the automatic adjustment of headlights consists of an adjusting element which interacts with an angle sensor. This arrangement can be connected with at least one control arm of a wheel suspension by means of a holding element which can be fastened to the control arm by means of a clamping pin and which has on its one free end extending beyond the control arm at least one bearing for an adjusting rod of the angle sensor.
