A high-seal automobile hub unit with an integrated structure and its assembly method

Abstract

The invention discloses an integrated high-seal automobile wheel hub unit and an assembly method thereof, comprising a base mechanism, the upper outer surface of the base mechanism is socketed with a transmission mechanism, and the upper outer surface of the transmission mechanism is socketed. There is a sealing mechanism, and a limit cylinder is vertically arranged in the middle of the upper surface of the circular plate. The invention relates to the technical field of automobile wheel hub units. The high-seal automobile wheel hub unit of integrated structure and its assembly method utilize the elasticity of springs. When the base mechanism needs to be assembled or disassembled, the staff only need to turn the knob to Drive the turntable on the rotating shaft to rotate, so that the positioning shaft on the eccentric rod can be inserted into or separated from the positioning groove inside the sleeve, and then the base mechanism can be fixed or disassembled on the transmission mechanism conveniently, replacing the traditional bolt fixing method, which not only saves The time for disassembly and assembly is shortened, and the labor intensity of labor is also reduced, which is convenient and quick.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hub units, in particular to an integrated high-seal automobile wheel hub unit and an assembly method thereof. Background technique [0002] With the continuous improvement of people's living standards, more and more families have cars, which bring convenience to people's travel, and the hub unit is an indispensable part of the car. The axle is used to bear the load and provide precise guidance for the rotation of the wheel hub. It bears both axial load and radial load, and is an important part of the car's load and rotation. [0003] The Chinese patent No. CN107791741A discloses a hub unit including an outer ring, an inner shaft, rolling elements and a sealing device, and the outer ring includes an outer ring body and an outer ring flange. The inner shaft includes an inner shaft body and an inner shaft flange. The outer ring body includes a first part and a second part. The first part ...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a high-seal automobile hub unit with an integrated structure and its assembly method, which solves the problem that the connection between the base part and the transmission part of the existing automobile hub unit is all through screws. Fixed connection, it is very inconvenient to disassemble or install, and the bearing on the hub unit is poorly sealed
