The invention relates to the technical field of vehicle brake components, and provides an electronic parking actuator and a vehicle. The electronic parking actuator is characterized in that the electronic parking actuator comprises a shell, a planetary gear mechanism and a motor which are arranged in the shell, the motor is connected with the planetary gear mechanism in a transmission way, the planetary gear mechanism comprises a disc-shaped planet carrier which is rotatable relative to the shell, the shell is provided with an inner annular surface matched with the outer peripheral surface ofthe planet carrier, and an oil storage groove is arranged on the peripheral surface of the planet carrier. According to the electronic parking actuator provided by the invention, the oil storage groove is arranged on the outer peripheral surface of the planet carrier matched with the shell, lubricating grease can be stored in the oil storage groove to lubricate the outer peripheral surface of theplanet carrier, the phenomenon that the lubricating grease cannot flow back after being extruded by the planet carrier and the shell is avoided, the problem that the planet carrier is difficult to lubricate is solved, and the service life is prolonged.
Description
Technical field [0001] The present invention relates to the technical field of vehicle brake components, in particular to an electronic parking actuator and a vehicle. Background technique [0002] In motor vehicle parking brake systems, especially in electronic parking brake systems, 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 and screw sleeve assembly in the caliper through the output shaft. The screw and screw sleeve assembly converts the torque into linear power to drive it. The piston, thereby clamping the brake disc, realizes 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 planetary gear mechanism has a sliding fit between the planet carrier and the housing. The ...
