Embodiment Construction

[0011] figure 1 Shown is the structure when the present invention is applied to a loader drive axle, including a hub 1, a brake disc 2, and a brake 3 connected to form a braking mechanism.

[0012] The structure of the present invention is as figure 2 As shown, the size of the radial contact surface of the brake disc 2 is: B=0.5-2mm, L=2-5mm; the surface of the axial contact surface A of the brake disc 2 is sprayed with 0.1-1mm thick low thermal conductivity Material.

[0013] In this embodiment, the low thermal conductivity material sprayed on the axial contact surface A of the brake disc 2 is an inorganic ceramic material, and the thermal conductivity is less than 1.

Abstract

The invention relates to a heat insulation brake disc of a drive axle. The brake disc is connected with a wheel hub through a bolt, and an axial contact surface A and a radial contact surface are formed between the brake disc and the wheel hub; the radial contact surface of the brake disc has the sizes that B is equal to 0.5-2mm and L is equal to 2-5mm; the surface of the axial contact surface A of the brake disc is sprayed with 0.1-1mm thick material with heat conduction coefficient less than 1. The heat insulation brake disc has the advantages that the change of the existing drive axle structure is not needed, the contact area between the brake disc and the wheel hub is reduced, the contact surface is sprayed with the material with low heat conduction coefficient, the heat is effectively prevented from being transferred to gear oil and an oil seal through the wheel hub, the service lives of the gear oil and the oil seal at a wheel rim are prolonged, the use reliability of the drive axle is improved, and the reliability of the gear oil and the oil seal at the wheel rim is improved; the structure is simple, and the use cost is low.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a thermal insulation brake disc of a driving axle. Background technique [0002] A loader drive axle in which the brake is arranged in the rim, the distance between the brake disc, the wheel oil seal and the wheel gear oil is small (about 10mm). During service braking, the heat generated by the brake will be quickly transferred to the gear oil and oil seal through the wheel hub. When braking frequently, a large amount of heat will be generated, and the heat can be quickly transferred to the gear oil and oil seal. Usually, the temperature of the brake disc during braking is about 150°C, and the maximum temperature can reach 300-400°C, which will cause the wheel side oil seal to age. life or failure. Contents of the invention [0003] The purpose of the present invention is to aim at the current brake disc without heat insulation measures, so that the heat can...
