A disc brake system comprises a mounting hub and at least one disc supported by the mounting hub. The mounting hub has a center portion and an outer portion substantially perpendicular to the center portion and defines a central axis extending perpendicular to the center portion. A plurality of grooves comprising a U-shape are defined within the outer portion and are spaced radially about the central axis. Each of the grooves extends axially relative to the central axis. A bearing is disposed in each of the plurality of grooves and operatively connects the mounting hub and the disc such that the bearing rotates about a bearing axis and moves axially within the groove in response to axial movement of the disc.

Disc brake system

An actuator for an electro-mechanical-brake motor assembly includes a housing surrounding a rotatable motor shaft presenting a longitudinal axis. A spring is non-rotatably supported on the housing. A latching device is non-rotatably supported by the housing. The latching device has a plurality of teeth. A latch gear is non-rotatably supported on the rotatable motor shaft and circumscribes the longitudinal axis and presents a plurality of axially facing angled teeth presenting a meshing engagement with the teeth of the latching device. The latching device is axially movable relative to the housing in response to magnetic force generated by the electric coil.

Park brake system having a latching device

A motor assembly, such as an electro-mechanical-brake (EMB) motor assembly includes an electric motor, a latch gear, a solenoid, and a spring. The latch gear is non-rotatably attached to the drive shaft of the motor. The spring is operatively connected to the solenoid and has a spring projection which is longitudinally-deflectable by energizing the solenoid. The gear tooth is shaped to longitudinally retain the spring projection when the latch gear rotates the gear tooth into engagement with the longitudinally-deflected spring projection. In one example, the latch gear is a parking-brake latch gear and the motor assembly provides a parking brake function for an EMB electric motor which also is used for applying and releasing a vehicle's driving brakes.

Motor assembly such as an electro-mechanical-brake motor assembly

The invention provides a brake caliper backdrive apparatus and method of backdriving a brake caliper. The apparatus includes a brake caliper, a motor including a shaft operably attached to the brake caliper and, a biasing member operably attached to the shaft. The biasing member backdrives the motor thereby releasing the brake caliper. The method includes rotating a shaft to clamp the brake caliper, storing energy in a biasing member responsive to the shaft rotation, and reversing the shaft rotation using the stored energy.

Brake caliper backdrive apparatus and method

An actuator assembly for a vehicle brake system or clutch pack comprises a motor shaft having a first tapered cutout, and a ballscrew shaft having a second tapered cutout. The first and second tapered cutouts being adapted to mate.

Actuator having common bearing

An actuator assembly for a vehicle brake system comprises a piston disposed in a bore, a reservoir, and a solenoid. A channel is in fluid communication between the bore and the reservoir, and the solenoid is disposed in the channel. The solenoid is movable between an open position and a closed position. In the closed position, the solenoid blocks fluid communication between the bore and the reservoir.

Vehicle brake by wire actuator

The present invention provides a sensor system for detecting lining wear and fluid level in a dry interface corner actuator for a single wheel brake including a reservoir assembly. The reservoir assembly includes a reservoir for containing fluid for the actuator and a sensor assembly positioned in the reservoir having a single set point to indicate both low reservoir fluid level and a need for brake lining replacement.

Dry interface corner actuator single sensor for lining wear and low reservoir detection

The present invention provides a reservoir cap and bleed mechanism for use with the fluid reservoir of a dry interface corner actuator. The reservoir cap and bleed mechanism displaces a portion of the reservoir volume during filling and provides a diaphragm to maintain a fill reservoir volume during operation. The fluid reservoir can be bled and filled to the desired brake fluid level through a sealable passage in the reservoir cap assembly without removing the reservoir cap.
