Safety composite type brake drum with rapid heat dissipation and anti-burst

Abstract

The invention discloses a safety composite type brake drum with a rapid heat dissipation and anti-burst. The safety composite type brake drum with the rapid heat dissipation and anti-burst comprises a brake drum shell. The brake drum shell is provided with an inner cavity. The brake drum shell comprises a main body part, a connecting part and an installing part, wherein the main body part, the connecting part and the installing part are sequentially connected in an integrated mode. Multiple reinforcing ribs are arranged at intervals on the outer ring wall surface of the main body part in an outward protruding mode. Each reinforcing rib extends in the axial direction, and each reinforcing rib is provided with a wind-proof surface. Air inlets are formed in the joints of the wind-proof surfaces and the outer ring wall surface of the main body part, and the connecting part is provided with air outlets. Accordingly, on one hand, the reinforcing ribs have the structural strengthening effect on safety composite type brake drum, on the other hand, the heat dissipation area is increased, and the heat dissipation effect is improved. Meanwhile, the wind-proof effect can be achieved, air can be driven to form airflow, the airflow flows into the inner cavity, and the heat in the inner cavity is driven out from the air outlets by utilizing the airflow. Therefore the timely heat dissipation or discharge can be achieved, the brake performance of the brake drum can be guaranteed, the burst phenomenon of the brake drum can be prevented, the service life of a product is prolonged, and the potential danger is prevented.

Description

technical field [0001] The invention relates to the technology in the field of brake drums, in particular to a rapid heat dissipation, explosion-proof and safe composite brake drum. Background technique [0002] Traditional motor vehicle braking systems include brake drums, brake shoes, brake mechanisms, etc. When a moving car needs to brake, the driver steps on the brake pedal, and the brake mechanism pushes the brake shoes, so that the brake shoes and the brake drum produce Braking friction, brake the wheels of the car, and realize the brake of the car. [0003] When the brake shoe and the brake drum produce brake friction, a lot of heat will be generated. However, the current brake drum structure fails to dissipate or discharge the heat in time, resulting in a decrease in the braking performance of the brake drum and prone to bursting, which shortens the life of the product. service life, but also has a great safety hazard. Contents of the invention [0004] In view o...
