The invention relates to a dust sheet for a vehicle brake configured for reducing brake noise, to a disk brake system comprising a dust sheet and to a method for making a dust sheet, wherein the dust sheet comprises, at least in a section, two or more layers.

A fastening device for a vehicle disc brake having a brake carrier includes holding fixture formed in the brake carrier for receiving a speed sensor. The brake carrier includes fastening members for mounting to a flange of the vehicle. The speed sensor is used for an anti-lock braking system to detect wheel slip. The holding fixture is in the form of a bore. The bore may be formed in the strut facing the axle or in an extension of one of the fastening members of the brake carrier. The speed sensor is aligned in its extension direction axially with an exciter in or on the brake disc or in the axle. The speed sensor is attached to a cable that does not need to be guided past the vehicle flange.

A system for the supplemental generation of energy from the operation of a vehicle operation, and specifically to the generation of energy in connection with a vehicle's drum brakes in combination with brushless electric motor-generators. The system includes a rotational conveyor that operatively connects the drum to a coupler member attached to a generator so that rotation of the drum rotates the coupler member to create energy. A frame member may position and retain the generator in place relative to the drum.

Disclosed herein an electric parking brake (EPB) system includes a first EPB provided on a left wheel of a vehicle; a second EPB provided on a right wheel of the vehicle; and a controller configured to determine an EPB that is to be operated alone from among the first and second EPBs in response to a gear being shifted to a P-stage, and operate the determined EPB alone.

A power transmission unit of a single-acting plunger type includes a ball screw, a ball nut driven by the ball screw, and a plunger piston coupled to the ball nut. A block housing at least partially encloses the plunger piston and the ball screw. A plunger chamber is at least partially defined by the block housing and a face of the plunger piston. The plunger chamber is selectively pressurized by reciprocal motion of the plunger piston with respect to the block housing driven by longitudinal motion of the ball nut. An electric motor selectively drives the ball screw to responsively reciprocate the plunger piston within the plunger chamber. A motor housing at least partially encloses the ball nut, the electric motor, and the plunger piston. The motor housing includes a block lip which is crimped to the block housing to maintain the motor housing in relation to the block housing.

A piston assembly for a disc brake assembly having a housing with a passage includes a piston provided in the passage and axially movable therein in response to hydraulic pressure. A rotatable spindle extends into the piston. A nut is threadably connected to the spindle such that rotation of the spindle results in axial movement of the nut within the passage to thereby axially move the piston. A damping member encircles the nut and has one of a sliding and rolling interface with the piston in response to relative axial movement between the nut and the piston to prevent rattling of the nut against the piston.

There is provided a brake lining for a railway vehicle that can reduce brake squeal in braking. A brake lining for a railway vehicle is used for a disc brake system of a railway vehicle. This brake lining includes a base plate, a sintered friction material, and a friction material supporting mechanism. The friction material supporting mechanism is disposed between the base plate and the sintered friction material and supports the sintered friction material in such a manner that the sintered friction material can move with respect to the base plate. The sintered friction material has a Young's modulus of 35.0 GPa or more.
