A roll stabilizer for a motor vehicle having a housing () with a first stabilizer element () coupled to the housing and an electric motor () located in the housing (). The transmission () is coupled to the electric motor () on a drive side, and the output side of the transmission () is coupled to a second stabilizer element () such that the stabilizer elements are electromechanically rotatable with respect to one another. The electric motor is designed as a Vernier motor.

A sensor device () for determining a steering angle (&#x3b4;) of a vehicle. The sensor device () is, or can be, fitted separately and/or retrofitted on a steering wheel () of the vehicle. The sensor device () comprises an accelerometer for the detection of an acceleration relative to at least two axes (gx, gy). The accelerometer is designed to emit a sensor signal that represents the detected acceleration in order to determine the steering angle (&#x3b4;).

A display device () for the display of data. The display device () includes a data display device () for displaying data. The display device () is, or can be, fitted separately onto a steering wheel () of a vehicle (). The display device () further includes an acceleration detection device () for detecting acceleration relative to at least two axes. The display device () is designed to determine, using the detected acceleration, a steering wheel rotational angle of the steering wheel () and, using the steering wheel rotational angle, to modify the data display.

A trailer coupling with a ball support and a coupling ball arranged at a free end of the ball support. A coupling ball holder is fitted onto and can rotate on the coupling ball. A locking element is provided on the coupling ball holder by which the coupling ball holder is secured against being inadvertently removed from the coupling ball. An angle measuring device, provided on the coupling ball, comprises sensors which can detect rotation of the coupling ball holder relative to the coupling ball about a rotation axis. The position of the locking element, relative to the coupling ball, can be determined using the sensors.

A twist beam axle for a wheel suspension of a motor vehicle. The twist beam axle has two trailing arms and a torsional profile having prismatic-shaped end sections with a noncircular cross-section. One trailing arm is connected to one torsional profile end section in each case. The trailing arms have a receiving recess having a shape corresponding to that of the outer surface of the torsional profile end section. An inwardly pressed plug is disposed in the interior of each torsional profile end section. The twist beam axle ensures permanent transfers high bending moments and torques between the trailing arms and the torsional profile without a welded joint. Different classes of materials can be used for the torsional profile and trailing arms, or can be connected to one another. The twist beam axle generally makes it possible to use large-volume, thin-walled and, therefore, weight-saving torsional profiles.

A torsion beam axle for a wheel suspension of a motor vehicle. The torsion beam axle has a torsionally compliant transverse section. A trailing arm is fixed at each opposed end of the transverse section. Each trailing arm supports a wheel carrier that pivots about a respective steering axis. The wheel carriers are connected to one another via ball joints and a tie rod, and couple an actuating mechanism for producing steering movement of the wheel carriers about their respective steering axes. A kinematic coupling system is connected to the tie rod and designed to regulate the degree of freedom of rotational movement of the tie rod. A torsion beam axle in which &#x2014;to minimizing track angle differences or unsymmetrical bouncing behavior&#x2014;the tie rod and actuating mechanism maintain optimum kinematic conditions in all operating situations.

A bearing mechanism for a transverse leaf spring mounted near a vehicle axle of a vehicle. The bearing mechanism has an outer bearing shell device and insertion devices, which are encompassed by the outer bearing shell device and comprise layer elements of different stiffness. The insertion devices are each disposed between the outer bearing shell device and the transverse leaf spring. First layer elements have a greater stiffness and are positioned between the transverse leaf spring and second layer elements with lower stiffness. The first layer elements are half-shell shaped and convex between end regions and oriented in the axial direction of the transverse leaf spring. The end regions of the first layer elements comprise regions that are concave with respect to the surface of the leaf spring, and free ends of which point away from the surface of the leaf spring.
