Automobile drive axle assembly

Abstract

The invention relates to an automobile drive axle assembly. An adapter device comprises an adapter inner barrel, a split gland and an adapter outer barrel; the adapter inner barrel and the adapter outer barrel are each provided with an inner hole, and the inner hole of the adapter inner barrel is in a shape engaged with the outer diameter of a main cone nut; and a cylinder shaft shoulder is arranged in the middle portion of the outer circumferential surface of the adapter inner barrel, the outer circumference of the cylinder shaft shoulder is matched with the inner circumference of the adapterouter barrel so that the adapter inner barrel is concentrically embedded into the adapter outer barrel, the split gland is of a semicircular step shaped structure, and the split gland and the adapterouter barrel are fixedly connected so that the adapter outer barrel can be prevented from falling from the adapter inner barrel and the adapter outer barrel can rotate relative to the adapter inner barrel. The automobile drive axle assembly has the beneficial effects that compared with the manner that a main cone flange needs to be fixed and the main cone nut needs to be rotated for tightening inthe prior art, the better accurate control effect and the better working efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an automobile drive axle assembly. Background technique [0002] The car drive axle assembly (usually the rear axle, and the four-wheel drive vehicle also includes the front axle) is the last assembly. The drive axle assembly is mainly composed of drive axle housing, final drive, differential and half shaft. The main reducer in the drive axle assembly bears large axial and radial impact loads, and its basic function is to transmit the power input from the transmission assembly to the driving wheels at last. The main reducer, also known as the main drive, is composed of a pair of spiral bevel gear assemblies, which are the driving bevel gear assembly and the driven bevel gear assembly. Its function is to reduce the speed, increase the torque, and change the direction of the rotation axis to ensure The car has plenty of traction and the right speed. Among them, the active bev...

AI Technical Summary

Problems solved by technology

The main cone nut 5 usually adopts an outer hexagonal structure, and the shaft 12 needs to be rotated at a certain angle to dock with the main cone nut 5; and due to the influence of the processing technology of the parts, each part will have some slight differences in size, which will It affects the alignment between the main cone nut 5 and the shaft 12. At this time, the problem of the butt joint between the main cone nut 5 and the shaft 12 becomes serious, which will seriously affect the assembly efficiency of the rear axle of the automobile.
