The present invention relates to the technical field of vehicle braking components, and provides an electronic parking actuator and a vehicle, wherein the electronic parking actuator includes a housing, a planetary gear mechanism and a A motor, the motor is connected to the planetary gear mechanism, the planetary gear mechanism includes a disc-shaped planet carrier that can rotate relative to the housing, and the housing is provided with a On the inner ring surface, an oil storage tank is arranged on the outer peripheral surface of the planet carrier. In the electronic parking actuator according to the present invention, an oil storage tank is arranged on the outer peripheral surface where the planetary frame cooperates with the housing, and the oil storage tank can store lubricating grease to lubricate the outer peripheral surface of the planetary carrier, so as to prevent the lubricating grease from being absorbed by the planetary carrier and the shell. After the body is extruded, it cannot be reflowed, which solves the problem that the planet carrier is difficult to lubricate and prolongs the service life.
Description
technical field [0001] The invention relates to the technical field of vehicle braking components, in particular to an electronic parking actuator and a vehicle. Background technique [0002] In the parking brake system of motor vehicles, especially in the electronic parking brake system, the rear caliper integrated electronic parking brake is easy to install and is widely used. [0003] In the rear caliper integrated electronic parking brake, the electronic parking actuator can amplify the torque output by the motor and transmit it to the screw-screw assembly in the caliper through the output shaft, and the screw-screw assembly converts the torque into linear power to push The piston clamps the brake disc to achieve parking. [0004] In the electronic parking actuator, in order to amplify the torque output by the motor, a planetary gear mechanism can be used. The planet carrier of the planetary gear mechanism is in sliding fit with the outer casing. The planet carrier and ...
