Problems solved by technology

[0002] The rear axle housing assembly of the existing casting type mini-car is as follows: figure 1 As shown, the vent plug 2 is installed on the back cover 1 of the casing, where the oil flow is intense, and the oil baffle plate needs to be welded inside the back cover 1 of the casing, which makes the back cover 1 of the casing complicated in process, difficult in forming, and high in cost. If the welding is improper, the effect of the oil baffle plate is not good, and the vent plug 2 will leak oil. At the same time, due to the complex structure of the shell back cover 1, it is easy to have stress concentration during molding, and there is a risk of cracking during use.

Abstract

The invention relates to automobile chassis, in particular to a rear axle housing assemble of an automobile in automobile chassis. The rear axle housing assembly of the automobile comprises a ventilation plug, an axle bag, a shell body rear cover and a separating plate, the shell body rear cover is connected with the axle bag, the separating plate is connected with the axle bag in an attached mode, a vent hole is formed in the axle bag, the vent hole is formed in the attachment position of the separating plate and the axle bag, and the ventilation plug is arranged in the vent hole. The rear axle housing assembly has the advantages that the mounting position of the ventilation plug is transferred to the axle bag from the shell body rear cover, the structure of the shell body rear cover is simplified, the stamping process of the shell body rear cover is simplified, manufacturing cost is lowered, the stress concentration of an axle tube is lowered, the separating plate has the function of an oil baffle, the normal work of the ventilation plug can be guaranteed, and the oil leakage defect of the ventilation plug is overcome.

Description

technical field [0001] The invention relates to an automobile chassis, in particular to a rear axle housing assembly of an automobile in the automobile chassis. Background technique [0002] The rear axle housing assembly of the existing casting type mini-car is as follows: figure 1 As shown, the vent plug 2 is installed on the back cover 1 of the casing, where the oil flow is intense, and the oil baffle plate needs to be welded inside the back cover 1 of the casing, which makes the back cover 1 of the casing complicated in process, difficult in forming, and high in cost. If the welding is improper, the effect of the oil baffle plate is not good, and the vent plug 2 will leak oil. At the same time, due to the complex structure of the housing back cover 1, stress concentration is easy to occur during molding, and there is a risk of cracking during use. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides an automobile r...
