摘要： A brake adjuster is provided for a vehicle brake such as for heavy duty vehicle. The brake adjuster includes a brake module that produces an electrical signal for adjusting the vehicle brake. The heavy duty vehicle brake typically includes a pair of pistons each having first and second portions that are movable relative to one another. A friction element or brake pad is arranged proximate to the second portion and is movable from a desired position to a worn position as the brake pads wear during operation of the vehicle. In one embodiment of the present invention, the first and second portions are slip fit within a sleeve assembly. At least one adjustment member is arranged between the first and second portions. The adjustment member is constructed from a material which expands in response to an electrical signal, such as a magnetostrictive or a piezoelectric material. The adjustment member moves the second portion relative to the first portion and repositions the brake pads from the worn position to the desired position. In another embodiment, the first and second portions are threaded to one another and movable rotationally relative to one another to adjust the length of the piston. The first portions of the pistons include a plurality of teeth about the outer face. A gear is arranged between the pistons and coupled the teeth of the first portions together. An electric actuator has a driven member that is coupled with at least a portion of one of the pistons teeth to rotate the first and second portions relative to one another to increase the length of the piston and move the brake pad from the worn position to the desired position.

摘要： A self-servoing disc brake assembly is provided that includes a driven rotor member having a first inner surface with a plurality of first pockets. The driven rotor member also includes a first friction surface spaced from the first inner surface. A movable rotor member is supported on the driven rotor member and is movable relative to the driven rotor member between non-servoed and servoed positions. The rotor members are spaced a first distance in the non-servo position, and the rotor members are spaced a second distance which is greater than a first distance in the servo position. The movable rotor member includes a second inner surface with a plurality of second pockets adjacent to the first inner surface and a friction surface spaced from the second inner surface. A plurality of balls are arranged between the first and second pockets with at least one of the first and second pockets being ramped. A friction member, such as a disc brake pad, is arranged adjacent to the second friction surface and is movable between engaged and non-engaged positions. The friction member is spaced from the second friction surface in the non-engaged position and the friction member is in contact with the second friction surface in the engaged position to rotate the movable rotor member to the servoed position and produce a supplemental brake clamping force. As the brake pads are moved into engagement with the driven and movable rotor members, a shear force is created on the second friction surface. The shear force causes the movable rotor member to rotate relative to and away from the driven rotor member. As a result, for a particular brake input force a larger braking torque is achieved.

摘要： A vehicle braking system includes a device for cooling the components of the brake assembly. The air source that is normally used to activate the brake assembly components is coupled with a plurality of flexible conduits that direct air toward one or more of the brake assembly components. A high velocity air nozzle preferably is provided at the end of each conduit. The air from the compressed air source is maintained in a compressed state through the conduits and decompresses as it exits the discharge nozzles. The decompression of the air through the nozzles results in cooling the air and the nearby brake components at which the air is directed.

摘要： The braking mechanism comprises a toggle lever, a brake pad, and an incline. An incline actuates the braking mechanism by forcing an extension of the toggle lever. As the toggle lever extends, it pushes the brake pad closer to the surface to be slowed. Multiple toggle levers may be used to distribute the force across the brake pad. This configuration allows a single input from the incline to actuate both toggle levers. By adjusting the width of the incline actuating the toggle lever, the force on the brake pad may be adjusted.

摘要： A brake slack adjuster is provided that includes a housing having an opening with a gear arranged within the opening. The housing includes a bore adjacent to the opening. A worm gear has an axis disposed within the bore and is an engagement with the gear. The worm gear has an end portion with helical teeth. An actuator loosely is arranged within the bore and includes an inner surface with complementary helical teeth engaging the helical teeth of the worm gear. An actuator rod includes an end arranged within the actuator aperture. The rod end is captured in the actuator by a retainer. A pawl assembly is supported by the housing and coacts with the actuator for retaining the actuator in a rotational position relative to the axis. Biasing members are arranged between the actuator and housing bore to urge the actuator engagement with the worm gear end portion. The actuator includes an elongated slot with and end of the pawl assembly captured with in the elongated slot to prevent rotational movement of the actuator relative to the housing. The elongated slot permits movement of the actuator in the direction of the axis.
