Abstract

The invention discloses an electronic brake actuator. The electronic brake actuator comprises an upper shell, a lower shell, a planet carrier, a duplex gear II, an output shaft arranged on the planetcarrier, a center pin arranged on the upper shell, a first elastic body arranged between the planet carrier and the lower shell and used for applying elastic acting force to the planet carrier, and / ora second elastic body arranged between the upper shell and the duplicate gear II and used for applying elastic acting force to the duplicate gear II. According to the electronic brake actuator, the elastic body is arranged and used for eliminating or reducing gaps among a plurality of parts on the planet gear main shaft, and therefore abnormal sounds generated by axial impact can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of brake systems, in particular, the invention relates to an electronic brake actuator. Background technique [0002] In the prior art, electronic brake actuators generally use two-stage fixed shaft gears and one-stage planetary gears. In the prior art, the planetary gear train, including the sun gear, more than three planetary gears and the planetary carrier, is installed in a cavity with the passive gear of the second-stage fixed-axis transmission, and the above-mentioned axial direction is in a clearance fit. Due to the size of the clearance The chain includes upper housing cavity tolerance, lower housing cavity tolerance, welding accuracy, height tolerance of the passive gear of the second stage fixed shaft transmission, thickness tolerance of the output shaft assembly, and the sum of the tolerances of many parts, resulting in a large axial clearance At the same time, so many parts are added together, a...
