A brake system for a vehicle has a brake pedal and at least one rotational part. The brake system further includes a shaft connectable to the rotational part, and a first fluid control unit configured for being filled with fluid and actuating in response to manipulation of the brake pedal. In addition, at least two cylinders in fluid communication with the first fluid control unit are provided. Each cylinder has a first cylinder end having an associated reciprocating piston and a second cylinder...

The invention relates to a wheel brake for a motor vehicle including an electromechanical actuating device and a hydraulic actuating device, which are redundant. In this way, the likelihood of failure of the wheel brake is reduced. A self-boosting device increases a braking force of the wheel brake, so that an (underpressure) brake booster can be dispensed with. Wheel slip control is possible in a simple way by hydraulic actuation of the wheel brake and superposition of a braking force regulatio...

Brake controller for controlling the brakes of a towed vehicle is provided. The controller includes microprocessor, an accelerometer, a storage array for storing a sequence of signals, and associated software for computing a moving average of accelerometer values thereby providing data on which the braking requirements of the towed vehicle can be determined. Feedback based on the power consumed during the braking event is likewise utilized to modify the power delivered to the braking system duri...

A disc brake comprises a torque-supporting member (10) with which is associated an actuating mechanism (28) to stress at least one friction element (22) against a rotating disc (18), this element (22) comprising a lining-holding plate (38) on which a friction lining is mounted. The plate (38) interacts so as to be anchored and to slide with guide surfaces formed on the torque support (10), and an anti-noise spring (48) interacts with the friction element (22) and with the torque support (10). Ac...

A brake system having a master cylinder for generating brake pressures in at least one closed brake circuit (I, II) and having an associated brake booster including a booster cylinder, a displaceable booster piston having a piston rod oriented into the master cylinder and a tappet arranged to plunge into the booster cylinder by means of a brake pedal and be displaced counter to the booster piston and is equipped with a brake valve connected to a pressure supply device, which brake valve is contr...

The brake comprises two shoes lined with friction elements stressed by a clamping mechanism located between two first ends of the shoes, a fixed anchoring block located between the other two ends of the shoes, and a spacer (44) mounted in the vicinity of the clamping mechanism and bearing by each of its ends on each of the shoes. The spacer comprises a device for automatic lengthening as a function of the wear of the friction elements and consists of a screw/nut system (66-72) controlled by a pa...

A disc brake has a support with a first end separated from a second end by first and second side walls that retain actuation members to move the first and second friction members into engagement with a rotor and effect a brake application. First and second perpendicular projections that extend from the support are aligned with the first wall and third and fourth perpendicular projections that extend from the support and are aligned with the second wall. The first and second friction members have...

The invention relates to a brake disc for a disc brake, in particular in motor vehicles. Said brake disc comprises a friction ring (12) and a pot-shaped supporting part (14), the friction ring consisting of several ring segments (18), which adjoin one another in a circumferential direction. To provide a construction that can be commercially produced in a cost-effective manner and that is not prone to warping, the ring segments are provided with semi-circular recesses (18a), which encompass retai...

A disc brake for a heavy road vehicle has a caliper arranged at a brake disc mounted on a wheel axle of the vehicle. An electric motor and two thrust rods operationally connected thereto are provided in the caliper. The thrust rods transform a rotational ingoing movement from the motor into a linear outgoing movement for transmission to a disc brake pad, intended for braking engagement with the brake disc.

A parking brake for a motor vehicle includes a lever holder, a brake actuation lever disposed in an articulated manner on the lever holder, a brake cable, and a coupling unit for tensioning the brake cable when the brake actuation lever is displaced. The parking brake also includes a locking device for holding the brake actuation lever in a locking position, and a four-bar mechanism including two nonparallel links for linking the brake actuation lever with the lever holder.
