The production process of the brake drum includes: 1) sand mold preparation: clay sand mold is used and the sand mold is placed in a sand box; 2) pouring: molten metal is injected into the sand mold to form a casting; 3) cleaning: removing sand grains and impurities on the surface of the casting; 4) welding: connecting the casting with other parts of the brake drum; 5) inspection: quality inspection of the casting; 6) surface treatment: surface treatment of castings, such as painting or plating; 7) Packing: pack the brake drum and prepare for transportation
When the temperature of the brake drum is too high, the following measures can be taken: 1. Open the water drench to reduce the temperature of the wheel hub; 2. If the vehicle does not have a water drench, the driver can stop and rest and wait for the brake drum to cool down naturally; 3. Repair the brake cylinder to solve the problem of brake drag; 4. Replace the brake drum spring and repair the damaged spring; 5. Adjust the brake pad gap to ensure that the left and right brake drum are consistent; 6. Add gear oil, solve the problem of poor lubrication; 7. Check and adjust the gap between the brake drum and the brake pad.
The out-of-roundness and radial runout of the brake drum working surface should also be strictly controlled to ensure braking performance. Alibaba provides a large number of brake drum products, including brake discs and brake drums for Mercedes-Benz, Audi, BMW and other cars, as well as brake drums for commercial vehicles such as trucks, trailers, and trailers.
The working principle of the drum brake is to push the piston of the brake master cylinder to move when the brake pedal is stepped on, and then generate pressure in the oil circuit. The brake fluid transmits the pressure to the brake shoe, causing it to expand outward and press toward the brake Drum, the components of drum brakes that generate braking torque include brake wheel cylinders, brake shoes, brake drums, friction pads, return springs, etc. Drum brakes have gradually withdrawn from the car field, mainly used for rear wheels and parking brakes with relatively small braking loads
