The invention provides a lightweight split type brake disc with heat dissipation structures. The lightweight split type brake disc is characterized in that the brake disc is composed of an upper discbody and a lower disc body, and a split structure is adopted; the upper disc body and the lower disc body are the same in structure, after the upper disc body and the lower disc body are mutually matched, fixing is conducted through cooperation of countersunk head inner hexagon bolts and hexagon thick nuts, and the contact positions of the hexagon thick nuts and the disc bodies are provided with anti-loosening opening gaskets; each disc body is of a three-circular-ring type heat dissipation structure provided with an outer-ring heat dissipation structure, a middle heat dissipation structure and an inner side supporting structure, wherein a certain structure relation is achieved among the above heat dissipation structures, through the structures, heat dissipation, strength, rigidity and other properties of the brake disc are guaranteed, meanwhile, lightweight of the brake disc body is achieved, and convenience is provided for brake disc assembling and brake disc whole and system main shaft assembling. The lightweight split type brake disc has the advantages that the structure is simple, design is reasonable, and usage is convenient.
Description
technical field [0001] The invention relates to the technical field of disc brakes, in particular to a lightweight split brake disc with a heat dissipation structure for a disc brake. Background technique [0002] The brake disc is the key component of the disc brake. The brake pads are pressed against both sides of the brake disc to generate friction to achieve braking, thereby ensuring the safe and stable operation of the rotating system. During the braking process, the friction between the brake pads and the surface of the brake disc does work, which quickly converts the kinetic energy of the system into heat dissipation, and the surface temperature of the brake disc rises sharply. Different degrees of thermal stress are generated inside the rotor, causing deformation of the brake disc and affecting the braking effect. [0003] Therefore, it is necessary to design a brake disc that can effectively dissipate the heat converted from kinetic energy and prevent the brake dis...
