Problems solved by technology

[0002] Automobile brake drum is the friction couple of drum brake. In addition to the strength and rigidity required as a component, it should also have as high and stable friction coefficient as possible, as well as appropriate wear resistance, heat resistance, and heat dissipation. Sex and heat capacity, etc., the brake pads on the car brake drum have high strength and wear resistance, but there are some problems in the use of some car brake drums now, and the brake pads are used for a long time when some car brake drums are in use. The braking effect becomes worse and needs to be replaced, but it is inconvenient to replace the brake pads when the brake drums of some cars are in use. However, some current automobile brake drums cannot dissipate heat and cool down the brake pads during use, which reduces the service life of the brake pads, and some current automobile brake drums are fixed on the automobile mounting plate by bolts and nuts , The contact between the nut and the brake drum is not well sealed, dust and water vapor will adhere to the bolt through the contact between the nut and the brake drum, and the bolt will be corroded, making it inconvenient to disassemble.

Abstract

The invention relates to the field of automobile brake drums, in particular to a high-strength wear-resistant automobile brake drum. The high-strength wear-resistant automobile brake drum comprises a main body device, a replacement device, a heat dissipation device and a sealing device; the main body device comprises a drum sleeve, a mounting plate, a rotating shaft and a controller; the drum sleeve is connected with the mounting plate in a sliding mode; the rotating shaft penetrates through the mounting plate; and the rotating shaft is rotationally connected with the mounting plate. According to the high-strength wear-resistant automobile brake drum, through the arrangement of a second motor, a gear, a rack and a positioning block, when a brake pad needs to be replaced in the use process, the controller controls the second motor to rotate, the second motor rotates to drive the gear to rotate, the gear rotates to drive the rack to move, and the rack drives the positioning block to leave away from the brake pad; when the positioning block does not make contact with the brake pad, the brake pad can be detached, and then a new brake pad is mounted in a connecting plate, the second motor is controlled by the controller to rotate reversely to enable the positioning block to be inserted into the brake pad, the brake pad is limited and fixed, the brake pad is mounted and fixed well, and therefore, the brake pad is convenient to replace in the using process.
