Limiting device of driving half axle bearing

Abstract

The invention relates to a limiting device of a driving half axle bearing, and relates to the technical field of automobiles, the limiting device comprises a support body and a sealing plate, the support body is provided with a first arc-shaped groove with an upward opening, and one side of the first arc-shaped groove protrudes upwards in the circumferential direction of the first arc-shaped groove to form a first limiting plate; one end of the sealing plate is rotatably connected with one end of the bracket main body, and the other end is detachably connected with the bracket main body; the sealing plate is provided with a second arc-shaped groove with a downward opening, one side of the second arc-shaped groove protrudes downwards in the circumferential direction of the second arc-shaped groove to form a second limiting plate, and the second limiting plate and the first limiting plate are arranged on the two sides of the support body respectively. During use, the sealing plate is connected with the support body, the first arc-shaped groove and the second arc-shaped groove jointly form a limiting space used for limiting radial movement of the bearing, the bearing is located in the limiting space, and the first limiting plate and the second limiting plate abut against the two sides of the bearing respectively so as to limit axial movement of the bearing. The support body and the sealing plate can serve as an integral part to be subpackaged offline in advance.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a limiting device for a drive half-shaft bearing. Background technique [0002] As the key part of the transmission system, the driving half shaft has an interference press-fitted deep groove ball bearing on its long handle section, which is used to support the driving half shaft and transmit rotational motion. Therefore, the installation and fixation of deep groove ball bearings is an important part of the installation and fixation of the driving half shaft, which affects the performance, cost, manufacturability, weight and other aspects of the overall plan. Therefore, the choice of installation and fixation scheme for deep groove ball bearings is relatively The essential. [0003] In related technologies, the installation and fixation of bearings usually includes axial and radial limits, see figure 1 As shown, the limit device of the bearing 1' includes a fixed ...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present application provides a limiting device for driving half-shaft bearings to solve the problem that the axial limiting of the bearing in the related art needs to be realized through the cooperation of a stepped hole, a limiting stopper and two bolts. The fixed bracket, the limiting The baffle and the two bolts are three different parts, which cannot be pre-assembled offline. There are problems such as a large number of parts, a complicated online assembly process, high cost, and a large system weight.
