An electromagnetic brake to restrict or prevent movement of a motor in a vehicle brake system, the electromagnetic brake includes: a core; a static plate; a moving plate located between the core and the static plate; a rotor located between the core and the moving plate; one or more legs that extend from the core; and one or more fasteners that connect the one or more legs to the static plate, the core includes a cylindrical portion and a flange that extends around the cylindrical portion, the one or more legs extend from the flange radially around the cylindrical portion.

Electric park brake with electromagnetic brake

A brake assembly comprising: (a) a caliper including: (i) one or more pistons, (b) one or more rotary to linear actuators that provides an axial force to move the one or more pistons, (c) a motor gear unit in communication with the one or more rotary to linear actuators, the motor gear unit including: (i) a motor, and (ii) an electromagnetic brake that prevents movement of the motor gear unit, the pistons, or both when the motor is turned off so that the brake apply is maintained.

An assembly that includes a main housing. A motor is supported in a motor housing that is supported in the main housing. The motor has an output shaft and a locking mechanism. The motor is adapted to generate a first rotational direction torque and a second rotational direction torque. The motor is adapted to transfer the first rotational direction torque and the second rotational direction torque to a destination via the output shaft. The locking mechanism is adapted to prevent the output shaft from back driving in the second rotational direction after the first rotational direction torque has been transferred to the destination. The motor housing is adapted to rotate in the main housing to unlock the locking mechanism so that the second rotational direction torque can be transferred to the destination.

Motor assembly

A brake system including a motor; a rotary to linear stage mechanism; and a torque locking mechanism. The rotary to linear stage mechanism in communication with the motor. The torque locking mechanism in communication with the motor. The torque locking mechanism comprises an electromagnet and a permanent magnet. During a brake apply the motor is adapted to move the rotary to linear stage mechanism so that at least one brake pad or at least one brake shoe is moved against a surface to create a clamp force. The electromagnet and the permanent magnet are adapted to cooperate to maintain the created clamp force.

Parking brake torque locking mechanism

An assembly includes a brake system comprising, a parking brake assembly including a first drive shaft and a second drive shaft. The assembly also includes two or more opposing brake pads, and a rotor extending between the two or more opposing brake pads. During use, the first drive shaft is moved so that a first portion of the brake pad is moved relative to the rotor, The second drive shaft is moved so that a second portion of the brake pad is moved relative to the rotor. One of the first portion of the brake pad or the second portion of the brake pad is moved relative to the rotor before the other of the first portion of the brake pad or the second portion of the brake pad is moved relative to the rotor.

Sequential parking brake assembly

A planetary gear assembly comprising: a housing, which contains: a planetary carrier, a sun gear, at least one planetary gear, a ring gear, a coil spring; an input shaft; and an output shaft. The coil spring extends around at least a portion of the planetary carrier. The coil spring includes a first tang in communication with the ring gear and a second tang in communication with the housing. When torque is applied to the input shaft, the planetary carrier rotates within the coil spring in one or more driving directions so that torque is transferred to the output shaft. When no torque is applied to the input shaft and torque is applied to the output shaft, the coil spring constricts and provides sufficient contact force to the planetary carrier and housing to prevent the planetary carrier from moving relative to the housing in at least one of the driving directions.

Planetary carrier with spring clutch

An assembly includes a brake system comprising a parking brake assembly including a first drive shaft and a second drive shaft. The assembly also includes two or more opposing brake pads, and a rotor extending between the two or more opposing brake pads. During use, the first drive shaft is moved so that a first portion of the brake pad is moved relative to the rotor, The second this shaft is moved so that a second portion of the brake pad is moved relative to the rotor. One of the first portion of the brake pad or the second portion of the brake pad is moved relative to the rotor before the other of the first portion of the brake pad or the second portion of the brake pad is moved relative to the rotor.
