High-sealing automobile hub unit of integrated structure and assembling method thereof

Abstract

The invention discloses a high-sealing automobile hub unit of an integrated structure and an assembling method thereof. The unit comprises a base mechanism, the outer surface of the upper portion of the base mechanism is sleeved with a transmission mechanism, the outer surface of the upper end of the transmission mechanism is sleeved with a sealing mechanism, and a limiting cylinder is verticallyarranged in the middle of the upper surface of a circular plate. The invention relates to the technical field of automobile hub units. According to the high-sealing automobile hub unit of the integrated structure and the assembling method thereof, by means of elasticity of a spring, when the base mechanism needs to be assembled or disassembled, a worker only needs to rotate a rotary knob to drivea rotary disc on a rotary shaft to rotate, a positioning shaft on an eccentric rod can be inserted into or separated from a positioning groove in a sleeve, then the base mechanism can be convenientlyfixed to or detached from the transmission mechanism, a traditional bolt fixing mode is replaced, the detaching and installing time is saved, the labor intensity of workers is reduced, and convenienceand rapidness are achieved.

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
