Problems solved by technology

[0003] However, due to the direct contact between the brake disc and the connecting surface of the hub, a large amount of heat generated by the brake disc during the braking process is directly transmitted to the hub and then to the bearing, resulting in a sharp rise in the temperature of the bearing and the loss of lubricating oil in the bearing. , can not play the role of lubrication; the deformation of the bearing due to high temperature affects its normal operation, which eventually leads to bearing damage and shortens its service life

Abstract

The invention discloses a heat insulation structure of a brake disc. The heat insulation structure is characterized in that the brake disc (1) is installed on a hub (3), heat insulation materials (2)are correspondingly arranged between the end surface of the brake disc (1) and the end surface of the hub (3) which are connected with each other and between the cylindrical surface of the brake disc(1) and the cylindrical surface of the hub (3) which are connected with each other. By the adoption of the technical scheme, heat insulation is increased or the contact area is reduced between the brake disc and the hub, and therefore, the excessive brake disc heat can be effectively prevented from being transmitted to a bearing, the working temperature of the bearing is prevented from exceeding the standard temperature, and the service life of the bearing is prolonged; and meanwhile, the temperature which can be tolerated in the working process of the brake disc can be improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering and relates to vehicle braking technology. More specifically, the present invention relates to thermal insulation of brake discs. Background technique [0002] Now that the speed of the vehicle is getting higher and higher, the brake disc is subjected to more heat during braking, and the disc temperature is higher. But the working temperature of the bearing needs to be controlled within a reasonable range. [0003] However, due to the direct contact between the brake disc and the connecting surface of the hub, a large amount of heat generated by the brake disc during the braking process is directly transmitted to the hub and then to the bearing, resulting in a sharp rise in the temperature of the bearing and the loss of lubricating oil in the bearing. , can not play the role of lubrication; the deformation of the bearing due to high temperature affects its normal operation, which eve...
