An adjuster for a strut located between first and second friction members for a drum brake. The strut has a shaft that is free to rotate in a first end member and threaded into the second end member. A lever pivots during a brake application and engages a ratchet wheel on the shaft to rotates the shaft and expand the strut to maintain a minimum running clearance with respect to a rotatable member. A bi-metal coil strip that is fixed to the strut has a free end that is aligned with the lever arm....

The brake system of the invention, during the ABS control mode, corrects the target slip rate in accordance with the turning of the vehicle, and determines whether the vehicle is running on a poor surface road. If the vehicle is running on a poor surface road, the system sets a target slip rate that provides a greater longitudinal force than the aforementioned target slip rate.

A braking system including a pre-charge with a plurality of pumps disposed in parallel with respect to one another. The pumps can direct pressurized brake fluid to the brakes during a controlled braking maneuver. The pumps operate with offset operating cycles such that a first pump is drawing fluid while a second pump is pushing fluid to the brakes. The invention provides an embodiment having three pumps operated in parallel, wherein the pumps define operating cycles offset 120 degrees from one ...

A retarder (16), as a braking device or auxiliary braking device for vehicles or the like, in particular rail vehicles, is described, having a stator (3), comprising at least two axially spaced-apart stator halves (3a, 3b), which each have magnetic field coils, and a rotor which is disposed between the at least two stator halves (3a, 3b), the rotor being coupled in a manner fixed against relative rotation to an axle (5) or shaft of the vehicle and the stator being coupled with the vehicle, or a ...

A braking force retaining unit has a cut-off valve and a control unit. The cut-off valve retains predetermined brake hydraulic pressure at the wheel cylinders until a predetermined releasing condition is established, even after the depression of a brake pedal is released when a vehicle is stopped. When the predetermined releasing condition is established, the retained brake hydraulic pressure is released, when the depression of the brake pedal is released, the control unit controls the cut-off v...

The present invention relates to a method for regulating a predetermined modifiable brake pressure in the wheel brakes of a brake system, wherein input quantities determining the brake pressure in the individual wheel brakes are evaluated and correcting variables of hydraulic valves are defined in a control and/or data processing system. To obviate the need for additional pressure sensors which register the pressure in the wheel brakes, it is arranged for by the invention that a characteristic c...

The protective device can be associated with a caliper body of a disc-brake caliper having a median plane of the caliper body which can be superimposed on a median plane of the disc arranged perpendicularly relative to an axis of rotation of the disc, the caliper body being arranged with a central portion astride the brake disc so that side walls thereof are arranged on opposite sides of the disc, the side walls of the central portion being connected to side portions so that the side portions ar...

Suspension system comprising a flat spring member having four legs. The legs are symmetrically arranged with respect to the center position of the spring member and each of the legs has a longitudinal axis and an end portion. A suspension frame is provided to support the spring member (by fixing the end portion of two legs. Two preload elements are arranged close to the end portions of two of the legs in a manner to apply a preloading force at those legs. The preloading force essentially points ...

A disk brake apparatus with a readily- releasable wear adjuster, including a brake caliper which overlaps a brake disk, a tensioning device for tensioning brake pads and an adjusting system for compensating for brake pad wear, where the adjusting system includes at least one adjusting rotating device with an electric motor drive for adjusting the brake pad clearance and a release device that assists in releasing the adjusting rotating device when the electric motor drive retracts the brake pads ...

A boosted brake for actuating a primary piston (54) of a master cylinder through a feeler and a reaction disk having a decompression piston (62) that is elastically returned by a spring (70). The decompression piston (62) has at least two radial branches (64) that are housed in the primary piston (54) of the master cylinder to provide two boost ratios that differ according to the intensity of an input force applied by an operator to effect a brake application.
