The invention relates to a deceleration strip differential mechanism assembly, and belongs to the technical field of automobile axles. The deceleration strip differential mechanism assembly mainly solves the problems that for an existing hyperbolic bevel gear speed reducer and an existing involute bevel gear differential mechanism, the size is large, the weight of the hyperbolic bevel gear speed reducer and the existing involute bevel gear differential mechanism is large, light weight is not facilitated, and the machining and assembling difficulty is relatively high. The deceleration strip differential mechanism assembly is mainly characterized by comprising a differential mechanism assembly body and a speed reducer assembly, wherein the differential mechanism assembly body comprises a differential mechanism left shell, a differential mechanism right shell, a planetary gear, a half-shaft gear, a straight-line shaft, a first end face bearing, a second end face bearing, a needle bearing,and a first connecting bolt; the speed reducer assembly comprises a speed reducer right shell, a sun gear, a planetary gear, a first ball bearing, a hollow straight-line shaft, a second ball bearingand a third ball bearing; and the speed reducer assembly is connected with the differential mechanism assembly body through a second connecting bolt to form the deceleration strip differential mechanism assembly. The deceleration strip differential mechanism assembly has the advantages that the size is small, the structure is simple and compact, the transmission efficiency is improved, realizationof reasonable utilization of space is facilitated, realization of the light weight is facilitated, and the assembly is convenient; and the deceleration strip differential mechanism assembly is mainlyused for an electric automobile.
Description
technical field [0001] The invention belongs to the technical field of automobile axles, and in particular relates to a speed reduction belt differential assembly which integrates a speed reducer and a differential. Background technique [0002] In traditional automobile axles, the main reducer generally adopts the integrated method of hyperbolic bevel gear reducer and involute bevel gear differential. Hyperbolic bevel gears and involute bevel gears are large in size, which is not conducive to the layout of the vehicle; their own weight is large, which is not conducive to lightweight; processing and assembly are difficult and costly. Contents of the invention [0003] The purpose of the present invention is to provide a speed reduction belt differential assembly with small size, compact structure, convenient assembly, reduced cost and reasonable space utilization in view of the above disadvantages. [0004] The technical solution of the present invention is: a speed reduc...
