Description

Automobile brake disc

Technical Field

The utility model relates to a brake disc technical field especially relates to an automobile brake disc.

Background

The brake disc is an important part in a disc brake device, two brake pads are controlled by a brake caliper to clamp the brake disc fixed on a wheel, and when the brake pads clamp a braking part of the brake disc, friction can occur between the brake pads and the wheel, so that the aim of braking the vehicle during running is fulfilled.

When the brake disc brakes, high temperature can be generated, the brake disc can be subjected to thermal expansion, the brake disc can slightly swing to form a proper angle, a most proper friction surface is arranged with the brake lining, the stability of the brake is kept, the area of the brake disc is increased, and the heat dissipation function of the brake disc is also facilitated. When the brake is braked for a long time or is braked with a large force, the friction surface of the brake disc generates high temperature due to violent friction and longitudinal expansion (namely, the diameter of the outer edge is expanded). If the brake disc is integrated, the outer edge expanded at high temperature and the cooler support are rigidly connected, strong internal pulling stress can be generated, the disc surface can be transversely distorted and deformed seriously, and the deformation is more obvious when the diameter of the brake disc is larger. In order to obtain larger braking torque, a high-performance braking system uses a large-diameter brake disc, and in order to avoid braking faults caused by serious thermal deformation of the brake disc, an engineer separates a friction surface at the outer edge of the brake disc from an inner side support, and the middle of the brake disc is connected by a special non-rigid structure, namely floating connection. The friction surface and the bracket form relatively independent stress surfaces, and when the friction surface expands when heated, the floating structure allows the friction surface to have a certain free longitudinal expansion space, so that the condition of generating internal pulling stress between the friction surface and the bracket can be eliminated, the friction surface is prevented from being distorted and deformed due to uneven heating, and the brake is more stable and reliable.
