A wheel suspension for a motor vehicle has a transverse control arm that can be attached to a vehicle body by way of bearings and a spring-elastic torsion bar assembly, and can be rotated about a longitudinal axis. The torsion bar assembly has a body spring that can be attached to the vehicle body with one end, and a transverse control arm spring that is attached to the transverse control arm with one end. The body spring and the transverse control arm spring are coupled with one another at their free ends. The transverse control arm spring and the body spring are coupled with one another by way of a setting element or a releasable connection, whereby the setting element or the releasable connection, respectively, allows rotation of the ends assigned to one another, for setting purposes.

Wheel suspension for a motor vehicle

A wheel suspension for a motor vehicle has a transverse control arm that can be attached to a vehicle body by way of bearings and can be rotated about a longitudinal axis, and a body spring configured as a torsion bar spring for absorbing rotational movements of the transverse control arm about the longitudinal axis. The body spring is disposed on the transverse control arm so as to rotate with it, with a first end. An electromechanical actuator for changing the angle of rotation of the body spring is disposed at a second end of the body spring. The wheel suspension has a damping element. The second end of the body spring is connected with a stress relief spring that is configured as a torsion bar spring, disposed coaxially with the body spring, and can be attached to the vehicle body.

A device for automatically controlling a track-bound vehicle, particularly a magnetic levitation vehicle is described. The device comprises a drive and brake system (), an additional brake (), a stationary mounted travel computer () and data carriers () arranged along the guideway for the supply of status signals in the form of location, speed or travel direction signals. In accordance with the invention the device also comprises means () which are arranged for safely stopping and/or starting the vehicle at or from preselected target stopping points () within the stopping zones (A) and which are so configured that an immediate decoupling of the vehicle from the drive and brake system () is effected when an impermissible travel status within the area of a stopping zone (A) is reached (FIG.).

A magnet arrangement for a magnetic levitation vehicle is described. The magnet arrangement comprises a plurality of magnet poles () being combined to form groups (to), wherein according to the invention each group contains one magnet pole (to) or two magnet poles (to). The windings (to) of each group are controlled by a control circuit () individually assigned to it (FIG.).

A magnet arrangement () for a magnetic levitation vehicle () is described. The magnet arrangement comprises at least one magnetic pole () consisting of a core () and a winding () applied to the core, a control circuit connected to the winding () and a power supply unit for supplying at least the electrical energy required for the control circuit. According to the invention, the magnet arrangement () is designed as an autonomous modular unit integrating within itself the magnetic pole (), the control circuit and the power supply unit (FIG.).

A device for controlling a platform door () located at the guideway () of a vehicle () is described. According to the invention, the device comprises, a sensor unit (), which is mounted at the guideway () and which serves to detect a preselected state of the vehicle (). An evaluating device () connected to the sensor unit () permits an opening of the platform door () only when the vehicle () is in the preselected state.

A method and a magnetic levitation vehicle operating with this method are described. For the control of support gaps () that are formed during operation of the magnetic levitation vehicle () between a track () and a number of carrying magnets () fastened to said magnetic levitation vehicle () and provided with windings (), wherein at least two carrying magnets () in adjacent positions act upon a suspension frame () of said magnetic levitation vehicle (), the electrical currents flowing through the windings () are so controlled that the support gaps () between these two carrying magnets () and the track () adopt pre-determined nominal values (na, nb). In accordance with the invention and in case that the currents through the windings () of the adjacent carrying magnets () are different under normal conditions, the nominal values (na, nb) for the support gaps () are altered such that the current through the windings (or) of a carrying magnet () with the lower electric current is increased and/or the electric current through the winding (and/or) of a carrying magnet () with the larger electric current is reduced.

The invention relates to a spring carrier for the chassis of a motor vehicle. Said carrier is used to support a coil spring () which is braced between two spring plates (). At least one of said spring plates () can be axially adjusted by means of a drive unit comprising a gearbox and an electric motor. Preferably, at least one part of the piston rod () and/or the shock-absorber tube () of a shock-absorber or a suspension strut is arranged inside the coil spring (). The aim of the invention is to develop one such spring carrier in such a way that the distance between the upper spring end and the vehicle body can be kept small in a cost-effective manner. To this end, the electric motor is embodied in the form of a ring motor having an external stator () and an internal rotor () which comprises a displacement nut on its inner side, said displacement nut axially displacing a spring plate carrier () connected to the spring plate () and externally embodied as a threaded spindle.
