Embodiment 1

[0034] Such as figure 1 and figure 2 As shown, in this embodiment, the positioning and assembly mechanism includes a locking screw 13, a positioning block 12 located on the outer side wall of the fixed plate 4, a positioning slot 11 located on the side wall of the installation groove 3, and a positioning groove located on the bottom surface of the installation groove 3. The positioning screw hole 15, the fixed plate 4 is provided with a matching positioning hole 14, and the locking screw 13 passes through the matching positioning hole 14 and is locked and connected with the positioning screw hole 15, and the positioning block 12 is snapped into the positioning groove 11 Cooperate. By setting a positioning groove in the mounting groove at one end of the half shaft, and setting a positioning block on the fixed plate to match with the positioning groove for positioning and clamping, it not only realizes the function of pre-positioning, but also has the function of limiting; thr...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that the connecting end of the spline shaft is arranged in a detachable connection structure, which facilitates the replacement of spline shafts of different specifications and improves practicability. Such as Figure 4 As shown, the spline shaft 2 is connected to one end of the half shaft main body 1 through a flange 17 . Specifically, a plurality of fastening holes can be provided on the circumferential side wall of the flange, and the fastening bolts can pass through the fastening holes to perform fastening installation and connection with the spline shaft. This structural setting facilitates the installation and disassembly of the spline shaft through the flange.

Embodiment 3

[0045] The difference between this embodiment and Embodiment 2 is that the free end of the spline shaft 2 is provided with a center 19 , and the free end of the spline shaft 2 is formed with an annular groove surrounding the center 19 . The center point is set at the free end of the spline shaft, which can contact with the cross shaft in the differential, reducing the wear caused by relative movement.

Abstract

The invention provides an axle half-shaft structure which comprises a half-shaft body, a spline shaft is arranged at one end of the half-shaft body, a mounting groove is formed in the other end of the half-shaft body, and the axle half-shaft structure further comprises a fixing disc and a positioning and assembling mechanism which is used for being clamped with the fixing disc in a positioning mode and locking and assembling the fixing disc in the mounting groove. The fixing disc is connected with the connecting rod through a connecting block, and a clamping groove used for clamping and assembling the connecting rod is formed in the fixing disc. Through the arrangement of the positioning and assembling mechanism, positioning clamping and locking assembly of the axle half shaft and the connecting rod are facilitated, the stability after assembly can be improved, and the strength of the half shaft can be improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an axle half shaft structure. Background technique [0002] The half shaft, also called the drive shaft, is the shaft that connects the differential with the drive wheels. The splines on the gear are connected with the reducer gear and the inner ring of the hub bearing. [0003] At present, the existing axle shafts have poor stability during assembly and are inconvenient to install and disassemble. In order to meet the strength requirements, the mounting surface of some half shafts has a relatively high weight, which is not conducive to the current lightweight requirements. Contents of the invention [0004] The present invention aims to solve the technical problems existing in the prior art. Therefore, the present invention provides an axle half shaft structure, the purpose is to facilitate the positioning and disassembly of the axle half shaft. [0005] Based on the a...
