A vehicle park lock actuator is arranged in a longitudinal axis and has a movable actuating element which is movable into a first position and a second position. A locking slotted guide, and a locking element is held displaceably perpendicular to the longitudinal axis and has a first surface and a second surface at a different distance from the longitudinal axis, and connected by a wedge surface with a gradient. The first surface is in operative contact with the locking element in the first position and a second surface is in operative contact with the locking element in the second position. At least the first surface and/or the second surface is inclined in relation to the wedge surface.

A gearing unit of a motor vehicle actuator, in particular an electric parking brake, includes a gearing housing in which a driven first shaft and a driving second shaft having fixed rotational axes are located. A first toothed wheel is mounted on the first shaft and a second toothed wheel is mounted on the second shaft. The first toothed wheel and the second toothed wheel engage with one another through a third toothed wheel. The housing for the third toothed wheel has at least two spatially offset bearing points in order to adjust a transmission ratio between the first shaft and the second shaft. An electric parking brake having a gearing unit is also provided.

The provided are a brake-by-wire (BBW) electronic control actuator unit and a use thereof. The BBW electronic control actuator unit includes a machine body, as well as a permanent magnet brushless direct-current motor (PMBDCM) and speed-reducing torque-increasing gear sets integrated in the machine body, where the PMBDCM includes a stator assembly and a rotor assembly; the rotor assembly is connected to one end of a motor shaft; the other end of the motor shaft is connected to an input end of each of the speed-reducing torque-increasing gear sets; an output end of the speed-reducing torque-increasing gear set is connected to an output shaft; and the output shaft extends out of the machine body. According to the BBW electronic control actuator unit and the use thereof, by assembling the PMBDCM and the speed-reducing torque-increasing gear set, there are advantages of a high mounting accuracy, and a compact structure.

A park brake caliper for a utility vehicle has an actuating unit, which is adapted to move a push rod, wherein the push rod is pre-tensioned by a tensioning device in one direction, but is adapted to be pressed in the opposite direction by a pneumatic, hydraulic, electromechanical or magnetic force, and an application unit which includes a brake lever, which is pivotably supported around a pivot axis and which is adapted to rest at the push rod at one side and at a bridge on the other side via an excenter. The application unit is adapted to be positioned around an axle of a utility vehicle. The bridge is adapted to press at least one brake pad against a brake disc of the utility vehicle. The lever points downwards towards the axle in all of its positions. A brake system is disclosed, where the park brake caliper and a service brake caliper are radially spaced from each other.

A personal transportation vehicle includes a seating area, at least one electric brake, and a receptacle containing electrical connectors that connect to the at least one electric brake. The seating area is sized to receive a driver operating the personal transportation vehicle. The at least one electric brake is disposed in an engaged position when an insufficient amount of power is delivered to the at least one electric brake and is disposed in a disengaged position when a sufficient amount of power is delivered to the at least one electric brake. In the engaged position, the at least one electric brake prevents the personal transportation vehicle from moving. The receptacle is accessible from the seating area during operation of the personal transportation vehicle.

An electric brake for an electric drive includes a brake coil housing joined to an electric motor end cap to form a brake compartment containing a first and second stator with a rotor assembly disposed between the two stators. The rotor assembly comprises isolators for vibration damping and alignment of brake pucks constrained by and rotating along with a rotor engaged to an output shaft of the electric motor. An adjustable plug, a spacer and a spring are disposed in the brake coil housing. The spring is compressed by the adjustable plug to apply a biasing force against the second stator to press the stator against the brake pucks of the rotor assembly, and an electric brake coil is positioned adjacent to the second stator to electromagnetically pull the second stator away from the pair of brake pucks when energized.
