US Patent:

6374959, Apr 23, 2002

Filed:

May 27, 1998

Appl. No.:

09/085985

Inventors:

Joseph A. Kay - Highland MI

Assignee:

Meritor Heavy Vehicle Systems, LLC - Troy MI

International Classification:

F16D 6900

US Classification:

188 731, 188250 R, 188250 B, 188 732, 188 711

Abstract:

Shoe and lining assemblies for use in disc brakes are disclosed that have centroids of the backing plate halves which are very close to the centroids of the actuator pistons. In this way, the forces from the pistons are evenly distributed across the backing plate surface area to result in better braking operation.

Joseph A. Kay - Highland MI

Assignee:

Meritor Heavy Vehicle Technology, L.L.C. - Troy MI

International Classification:

F01M 1104

US Classification:

1841052, 188264 B

Abstract:

A system continuously lubricates critical areas, such as bushings and seals, in a cam brake shaft. A fresh source of lubrication is provided at a generally constant pressure. This is accomplished using a centrally located spring and an adjacent pair of axially sliding inboard seals that apply a continuous pressure to strategically disposed lubricating fluid between each of a pair of main seals at each end of the tubular cam housing and a respective inboard seal positioned at an end of the centrally located spring.

International Classification:

F16D 55/08

US Classification:

188 728

Abstract:

A brake assembly has a caliper with a first brake pad and a second brake pad. The first brake pad is moveable relative to the caliper. A brake actuator moves the first brake pad and has a first threaded member and a second threaded member. The first threaded member has first thread characteristics for moving the brake actuator at a first speed and a first force. The second threaded member has a second thread characteristics for moving the brake actuator at a second speed and a second force. The first speed is greater than the second speed while the first force is lower than the second force.

International Classification:

F16D 55/14
F16D 55/46

US Classification:

188 722, 188 28, 188 729

Abstract:

A self-energized disk brake assembly includes gain stabilization features for controlling the multiplication of applied force against a rotatable brake member. The brake assembly includes a first brake pad supported about a first pivot and a second brake pad supported about a second pivot. An actuator applies a force to drive the brake pads into the rotatable brake member. Frictional force between the brake pads and the rotatable brake member pulls the brake pads into further engagement generating an increase in braking force from self-energization. A position of the first and second pivots is adjustable to control the amount of braking force generated from self-energization.

International Classification:

F16D 51/00
F16D 65/14

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.

International Classification:

F16D055/08

US Classification:

188/072100, 188/156000, 188/158000

Abstract:

A brake system includes a rotor and a brake pad. An actuator is connected to the brake pad. The actuator includes an energy receptive material that expands when excited to move the brake pad into contact with a braking surface on the rotor. A drive unit moves the energy receptive material between a first position and a second position, where the second position is closer to the rotor than the first position. An energy source energizes the energy receptive material to expand, moving the brake pad into contact with the braking surface. A control unit controls the drive unit and the energy source.

International Classification:

F16D055/08

US Classification:

188072700

Abstract:

A brake assembly includes a brake pad movable on a support. The support is pivotally mounted to provide adjustment of an angle defined between the support and a centerline of a rotor. A force applied to the brake pad causes engagement between the rotor and the brake pad. A frictional force drives the brake pad along the support to increase the magnitude of braking force beyond the force applied by the actuator. The increase in braking force is proportionally controlled by adjusting the angle.
