Assembly method for screwed hub brake disc assembly for commercial vehicles

Abstract

Disclosed is an assembling method of a screw-type hub brake disc assembly and for a commercial vehicle. The screw-type hub brake disc assembly comprises a hub composed of a hub flange and a hub bearing position. A brake disc comprises a brake disc body. Connecting key grooves are formed in the inner ring of a circular disc, facing one side of the hub, of the brake disc body. Connecting splines arearranged on the outer wall of the hub bearing position. Positioning reinforcing bars are arranged at the positions, corresponding to the outer wall of the hub bearing position, of the side surfaces,facing the hub flange, of the connecting splines. The positioning reinforcing bars protrude out of the top surfaces of the connecting splines. Pressing rings are mounted on the other side surfaces ofthe connecting splines through pressing screws. The pressing rings press the circular disc, facing one side of the hub, of the brake disc body on the positioning reinforcing bars. The assembling method of the screw-type hub brake disc assembly comprises the steps that the connecting key grooves in the brake disc body are aligned with the connecting splines on the hub, and the brake disc body is mounted on the hub in a radially-positioned mode through the connecting splines and the connecting key grooves; and the brake disc body is axially pressed on the positioning reinforcing bars by using the pressing rings and locked by using pressing screws. The assembling method is suitable for the commercial vehicle.

Description

technical field [0001] The invention relates to the field of commercial vehicle hubs, in particular to an assembly method for a screw-type hub brake disc assembly for commercial vehicles. Background technique [0002] At present, medium and heavy trucks and buses are widely used in road transportation and engineering transportation. As an important transmission link between the ground and the body, the hub brake disc assembly determines the driving safety and economy of the whole vehicle. The existing hub brake disc assembly generally includes a hub and a brake disc, wherein the hub is composed of a hub flange and a hub bearing position, the brake disc is composed of a brake disc body and a brake disc sleeve, and the brake disc passes through The brake disc sleeve is set on the hub bearing position of the hub and fixed by fixing bolts. This existing hub brake disc assembly has the following problems in actual use: [0003] Since the brake disc is set on the hub bearing pos...

AI Technical Summary

Problems solved by technology

[0003] Since the brake disc is set on the hub bearing position of the wheel hub through the brake disc sleeve and fixed by the fixing bolts, the fixing bolts will be subjected to a large shear force. In this way, in order to ensure driving safety, the size of the fixing bolts must be designed The size of the fixing bolt is very large, and the installation of the fixing bolt is very laborious and time-consuming
