International Classification:

F16D 6538

US Classification:

188 717, 188 111 R, 188 111 W, 188196 M, 188 7026

Abstract:

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.

International Classification:

F16D 6538

US Classification:

188 7339, 188 731, 188250 B

Abstract:

A universal friction lining support is affixed on or just under the surface of a friction lining to resist wear and vibrations caused by the road, eliminating the need for a backing plate. The support is configured to fit in the corners of friction linings of various lining assembly sizes. Extensions on the exterior edge of the support locate the friction lining relative to the caliper housing as the piston is engaged. Various attachment features, such as holes or protrusions, can be also added to the support to secure the support to the friction lining.

International Classification:

F16D 5508

US Classification:

188 727, 74110, 74520

Abstract:

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.

International Classification:

F16D 6500

US Classification:

188 731, 188 722, 188 727

Abstract:

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.

US Classification:

188 7955, 188196 V

Abstract:

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 plurality of floating rotors are slidingly attached to the fixed rotor and a plurality of stationary friction surfaces are interleaved therebetween. The stationary friction surfaces are keyed to the caliper housing allowing for axial movement. The floating rotors are connected to the fixed rotor by pins, or are axially slidingly keyed at the inner radial periphery to splines on the fixed rotor.

US Classification:

18820600A

Abstract:

A brake spider includes a spider body with a central opening and a slot for receiving a camshaft and bracket assembly. The brake spider is attached to an axle housing via the central opening. The slot is defined by an inner surface that does not completely surround the camshaft. The slot allows the camshaft and bracket assembly to be removed from a wheel end assembly for service operations without having to remove other components from the wheel end assembly, such as a wheel hub, for example.

US Classification:

18825000B, 18825000G

Abstract:

A brake component assembly includes a support plate and a friction lining mounted to the support plate with a plurality of fasteners. A sealing barrier is formed between the support plate and the friction lining. A liquid material is initially applied to at least one of the support plate and friction lining, which are then fastened together. The liquid material subsequently forms the sealing barrier between the support plate and the friction lining. Optionally, a flexible gasket is used to form the sealing barrier. The flexible gasket is sandwiched between the support plate and friction lining when the support plate and friction lining are fastened together.
