Abstract: A brake monitoring and control system includes a brake pad adapted to frictionally engage a brake disc when the brake is applied, a motor operatively attached to the brake pad, the motor causing the brake pad to be located in an unapplied position in response to a compensation signal and causing the brake pad to move to an applied position in response to a control signal, and an electronic control unit in communication with the motor. The electronic control unit receives, from a motor position sensor, motor position indicative signals indicative of an angular position of the motor when the brake pad is in the applied position, and calculates the compensation signal based at least in part upon the angular position of the motor when the brake pad is in the applied position.

Abstract: A transmission brake is arranged in connection with an electric motor for an electric brake. The transmission brake shall allow rotation of the motor shaft in a brake applying direction, but when motor current is no longer supplied, the shaft shall be locked. Rotation of the shaft in the brake release direction pre-supposes reverse rotation of the motor. A clutch is arranged between the shaft and a non-rotational housing. For accomplishing an engagement of the clutch at a rotation of the shaft but not the motor in the brake release direction there is a ramp.

Abstract: A spring brake actuator is mounted with its shaft connected to the rotational operative shaft of a service brake actuator. The spring brake actuator has a clock spring, which is mechanically charged at a rotation of the actuator shaft in a brake release direction. It also has an electric coil for keeping when electrically energized—the clock spring in its charged condition. Further, it has means for transferring the rotative energy of the clock spring to the actuator shaft in a brake applying direction, when the coil is energized, but allowing free rotation of the shaft in either direction, when the coil is energized.

Abstract: In a vehicle air is compressed for being used in the brake system of the vehicle, for instance. In the compressor, used for the compression, the air is contaminated with oil and solid particles. In order to be relieved from these particles, before the air is conveyed through a drying filter, the compressed is brought to rotation by means of a rotating member in a centrifugal separator. The rotating member may advantageously include a pile of conical separation discs forming flow passages between each other for the compressed air to be cleaned. By means of an efficient cleaning of the compressed air from particles the life time of the drying filter may be increased.

The thrust yoke is provided with braces going diagonally from the center of the thrust yoke down to the backside of the thrust plate. The structure of the thrust yoke ensures that the force is applied in distinct, separated areas of the brake pads. The brake mechanism is held together as one unit which facilitates handling and assembly.
