Bolt type hub brake disc assembly with heat dissipation for commercial vehicle

Abstract

The invention discloses a bolt type hub brake disc assembly with heat dissipation for a commercial vehicle. The bolt type hub brake disc assembly comprises a hub and a brake disc, wherein the hub is composed of a hub flange and a hub bearing position; the brake disc comprises a brake disc body; a plurality of connecting key slots are formed in positions, in the peripheral direction, on the circular disc inner ring at one side, towards the hub, of the brake disc body; connecting splines are arranged on positions, which correspond to the brake disc body in the peripheral direction, on the outerwall of the hub bearing position; the brake disc body is mounted on the hub bearing position through the connecting key slots and the connecting splines; positioning reinforcing ribs are arranged on positions, which correspond to the outer wall of the hub bearing position, on the side surfaces, towards the hub flange, of the connecting splines; the positioning reinforcing ribs are bulged out of the top surfaces of the connecting splines; a pressing ring is arranged on the other side surfaces of the connecting splines through a pressing bolt; the pressing ring is used for pressing the brake disc body at one side, towards the hub, of the brake disc body onto the positioning reinforcing ribs; a spline vent hole is formed between root parts of every two adjacent connecting splines; and a plurality of flange vent holes are formed in the peripheral direction of the hub flange. The bolt type hub brake disc assembly is suitable for the commercial vehicle.

Description

technical field [0001] The invention relates to the field of commercial vehicle hubs, in particular to a screw-type hub brake disc assembly with heat dissipation 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] 1. Since the brake disc is set on the hub bearing p...

Problems solved by technology

[0005] 3. Since the brake disc is set on the hub bearing position of the hub through the brake disc sleeve, the entire hub brake disc assembly is a closed structure, resulting in low heat dissipation efficiency, and a large amount of heat accumulated on the brake disc will seriously affect the The braking effect of the brake disc will affect driving safety
