Light-weight high-strength automobile tail door electric driving reducer

Abstract

The invention discloses a light-weight high-strength automobile tail door electric driving reducer. The light-weight high-strength automobile tail door electric driving reducer comprises a two-stage planetary reducer (1), a connecting head (2) and a coupling (3). The two-stage planetary reducer is composed of a reducer shell, a wheel core A and a wheel core B, wherein the reducer shell is providedwith an inner bevel gear, a mortise, a bayonet and a conical head buckle, the wheel core A is provided with a core shell A, a shaft frame A, a wheel shaft, a planetary gear A and a revolution gear A,and the wheel core B is provided with a core shell B, a shaft frame B, a planet gear B and a revolution gear B. The connecting head is provided with a connecting key, a tenon and a hook buckle, and the coupling is provided with a gear hole. The inner-bevel-gear-structure two-stage planetary reducer is adopted, and the wheel core A and the wheel core B are made of full-plastic materials are connected in series and share the reducer shell, so that the technical indexes of the tail door speed reducer are met, and the technical scheme meeting further lightweight requirements is achieved; and theproduction and application of the automobile tail door electric driving speed reducer are met, the purposes of reducing the size, reducing the weight, achieving further lightweight, improving the efficiency and reducing the cost are achieved.

Description

technical field [0001] The invention relates to an automobile electric tailgate reducer, in particular to a light-weight and high-strength automobile tailgate electric drive reducer used for the lift switch of the electric automobile tailgate. Background technique [0002] The tailgate electric drive reducer is referred to as the tailgate reducer for short. The tailgate reducer is a component used to reduce the speed of the motor to drive the car tailgate to open and close. With the increasing development of automobiles, the tailgate is required to be decelerated The quality of the device is improved in the direction of high precision, high strength, long life and light weight; [0003] The tailgate reducer in the prior art adopts a worm gear reducer made of copper alloy, which is large in size, with a diameter ≥ 26mm; heavy in weight, ≥ 70 grams, and consists of 24 parts; it is difficult to meet the further requirements of foreign car companies for the tailgate reducer.
