Description

Technical Field

[0001] This utility model relates to the field of axle technology, and in particular to an axle assembly. Background Technology

[0002] Chinese patent document CN215971463U, published on March 8, 2022, discloses a low-bed maintenance-free disc brake shaft, comprising a main shaft, a base plate, and a brake. A hub is rotatably connected to the end of the main shaft. The base plate is fixed to the main shaft. The brake includes a brake caliper, an air chamber, and a brake disc. The brake caliper is fixed to the base plate, and the air chamber is connected to the brake caliper. The air chamber drives the brake caliper to restrict the rotation of the brake disc. The inner diameter of the hub is larger than the outer diameter. A flange protrudes from the outer circumference of the hub, and the flange has several first through holes distributed at equal intervals around the circumference. The brake disc includes an inner disc and an outer disc, which are connected and fixed by a connecting ring. The inner disc corresponds to the brake caliper, and the outer disc is adapted to the flange. The outer disc has second through holes corresponding to the first through holes. This brake shaft's hub lacks a heat dissipation structure, resulting in excessively high brake disc temperatures and reduced service life.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an axle assembly that is simple in structure, has good heat dissipation, long service life, low cost, and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] A heat dissipation hub designed for this purpose includes a main body, characterized in that: a flange is provided at one end of the main body, and a plurality of heat dissipation holes are evenly distributed in a ring on the flange.

[0006] The heat dissipation holes are evenly distributed in a ring on the outer periphery of the main body.

[0007] The ventilation holes are located close to the main body.

[0008] The flange extends to the outer side of one end of the main body, and several annularly distributed reinforcing ribs connect the flange to the main body, with heat dissipation holes formed between adjacent reinforcing ribs.

[0009] The reinforcing ribs are elongated to make the heat dissipation holes elongated as well.

[0010] The outer edge of the flange has several first fixing holes evenly distributed in a ring, and the heat dissipation holes are located inside the first fixing holes.

[0011] An axle assembly designed for this purpose includes an axle and a brake disc, characterized in that it further includes the aforementioned heat dissipation hub, which is mounted on the axle, and the brake disc is mounted on the heat dissipation hub. A heat dissipation channel is formed between the heat dissipation hub and the brake disc, and heat dissipation holes are connected to the brake disc through the heat dissipation channel and are connected to the outside.

[0012] The brake disc includes a brake body and a sleeve. The sleeve is fitted onto the body, and a heat dissipation channel is formed between the sleeve and the body. The heat dissipation holes are connected to the brake body through the heat dissipation channel.

[0013] The brake disc has several second fixing holes evenly distributed in a ring. After the fastener passes through the first fixing hole, it is fastened to the second fixing hole to connect the heat dissipation hub and the brake disc.

[0014] This invention creates several heat dissipation holes on the flange surface of the wheel hub. The heat dissipation holes are evenly distributed in a ring, forming a heat dissipation channel between the heat dissipation wheel hub and the brake disc. The heat dissipation holes are connected to the brake disc through the heat dissipation channel and are also connected to the outside. Cold air from the outside enters the brake disc through the heat dissipation holes and the heat dissipation channel in sequence, dissipating heat and cooling the brake disc, effectively reducing the wheel end temperature, thereby reducing the brake disc temperature and ensuring the service life of the brake disc.
