Abstract: The invention involves a spring for a floating caliper disc brake with a frame jaw caliper which, in the middle section of its axial outer edge, has a side window and on both sides of this window openings for an axial bracket of a fixed brake anchor plate. The caliper is displaceably and axially mounted on the bracket of the brake anchor plate. Brake linings are attached on both sides of the disc brake to the bracket of the brake anchor plate in an axial, displaceable manner and are also overlapped by the frame jaw caliper. The invention includes a onepiece curved wire holding spring, the middle section of which is releasably attached to the axial outer brake lining and which has two springs arms that are essentially placed in a contrary tangential direction to the middle section. The holding spring biases the frame jaw caliper radially against the brake anchor plate and biases the axial outer brake lining axially against the inside of the outer edge of the frame jaw caliper.

Abstract: The invention relates to an electric brake system for a motor vehicle wherein each wheel of the vehicle includes a brake actuator (2) assigned thereto. The invention also relates to a brake actuator for an electric brake system. During a braking operation, the brake linings (20a and 20b) are pressed against the brake disc (30) with a pregiven braking force by a braking-force device (10) of the brake actuator (2). At least one of the brake actuators (2) includes a sensor with which an elastic deformation of the braking-force device (10) or the brake yoke (18) is measured. This elastic deformation occurs during a braking operation. The braking force is determined from the measured elastic deformation and this braking force is then available for the control of the brake system.

Abstract: The present invention relates to a process and a control system for generating defined actuating forces in a brake which is electrically operable by way of an actuator, wherein there is a first static relation between the brake's actuating travel and the actuating force. The process and the control system permit determining the actuating forces which develop during operation without additional sensors. To achieve this object, according to the present invention, a second relation which corresponds to the operation of the brake is determined from the first relation and an information which represents the variations of the first relation.

Abstract: The invention relates to a system having an air spring flexible member (6) which is clamped between a cover plate (4) and a rolloff piston (10). The movement of the rolloff piston (10) is pregiven by a curved path (16). The rolloff piston (10) is curved with the curvature being at least segmentwise of the same orientation as the curvature of the curved path (16). Because of the curvature of the rolloff piston (10), a lateral offset of the flexible member (6) to the cover plate (4) can be substantially avoided when the rolloff piston (10) plunges into the flexible member (6). The formation of a rolling lobe (20) having a different width over its periphery is also avoided.

The input signal conditioning and the processing in accordance with simplified algorithms are installed in a third microprocessor system (4).

Abstract: A method for controlling or regulating a compressor 4 that can be switched on and off on demand, wherein a control unit 6 that switches the compressor 4 on and off is provided with the compressor. In a method of this type, it must be ensured that the compressor 4 is not damaged due to overheating. This is attained due to the fact that the control unit 6 operates the compressor 4 continuously during a regulating process until a limiting value is reached, and that said control unit operates the compressor in a cyclic manner once the limiting value is reached. This method makes it possible to complete regulating processes even if a critical limiting value is already reached.

The roller support elements 26 project from the elongate support member 24 and the elongate support member 24 is laterally offset and spaced from a common longitudinal axis of the helical pathways for the roller mounting members 28 so that the space radially inwards of the helical pathway is substantially unobstructed.

Abstract: An arrangement for bearing a non-driven wheel in an automotive vehicle or the like, includes a carrier unit, a wheel hub and an anti-friction bearing.The arrangement provides thatthe wheel hub (1) is integrally formed with a trunnion;a one-piece or bipartite inner ring (2a) of the anti-friction bearing (2) is secured to the trunnion (1a), andan axle body (3) having a bore (3a) for accommodating an outer ring (2b) of the anti-friction bearing (2) is provided as the carrier unit.As the outer ring of the anti-friction bearing is arranged directly in the axle body (3), no screw operation is any longer required for securing the bearing means to the vehicle. As the inner ring is secured to the trunnion (1a) of the wheel hub (1) by roll rivets, there is no need for the otherwise required bearing adjustment during final assembly. The measures according to the invention involve the advantage that the number of components and also the efforts to be taken in the final assembly are decreased.

A plurality of second marks is arranged in a circular pattern on a radially inner area of the sidewall. Passing of the first and second marks is detectable by magnetic or inductive sensors. The derived signals are used to determine the longitudinal force acting on the tire or the tire spring travel or the footprint length or the load/pressure ratio during rotation of the tire.

Abstract: The present invention relates to an electromechanically operated disc brake for motor vehicles, which consists of a floating-type brake caliper as well as an actuating unit arranged on the caliper. The actuating unit exhibits an electric motor which adjusts an actuating element via a reducing gear. The actuating element in turn causes one of two friction linings provided in the brake caliper in a displaceable manner to be brought into engagement with a brake disc. In order to be able to maintain high clamping forces with very low electric power, the present invention proposes that means (20 or 21,22) be provided to prevent reverse rotation of the rotor (10) of the electric motor (6) when the current supplied to the electric motor (6) is switched off after said electric motor (6) was activated. At the same time, this measure minimizes heating of the electric motor.

The non-return valve (1) is configured as a plate-type non-return valve with a flow opening (2) which is aligned coaxially to a first opening (3) of the valve seat member (4). Relative to the first opening (3) at least one bypass opening (5) is provided in the valve seat member (4) which is either closed or opened by a sealing surface (6) located to the side of the flow opening (2) of the non-return valve (1). A compact non-return valve (1) which is especially simple to make is thereby achieved.

Abstract: The invention relates to a roller spindle assembly (2) having a spindle rod (4) and a spindle nut (6) and roller bearings (10). The roller bearings are journalled between the spindle nut (6) and the spindle rod (4). The spindle rod (4) and the spindle nut (6) move relative to each other and, for a relative movement of the spindle rod to the spindle nut (6), the roller bearings (10) are displaced out of a start position. The roller bearings (10) are journalled in a cage (8) resiliently biased by a return spring (12). With the cage (8), the roller bearings (10) are guided back into the start position after a completed displacement from the start position when the spindle rod (4) and spindle nut (6) are at rest. In this way, it is not necessary to provide a conventional return of the roller bearings (10) with the aid of complex return-guide channels in the spindle nut (6).
