Description
Technical Field
The utility model relates to a stopper heat dissipation field especially relates to a forced air cooling and water-cooling drum brake.
Background
Most of the existing trucks adopt drum brakes. The drum brake consists of brake drum, brake shoe, friction plate, brake wheel cylinder and other parts. The brake drum rotates with the wheel and the brake shoes and friction plates are mounted on a backing plate and are stationary relative to the vehicle. When the automobile runs, when a driver brakes the brake, the driver steps on the brake pedal, the brake shoe drives the friction plate to press the brake drum under the pushing of the brake cylinder piston, and the brake drum is acted by the friction force to decelerate or stop the automobile. Due to the large load capacity of the truck, relative friction under high pressure occurs during braking, thereby generating a large amount of heat. The friction material can generate heat fading when the temperature rises, and when the heat fading occurs, the friction force is reduced, so that the braking effect is greatly reduced. In particular, the braking effect is poor due to long-time downhill braking, and an automobile accident is caused in severe cases. Therefore, when the brake generates a large amount of heat and the temperature rises, the heat of the brake system must be dissipated, so that the heat fading is reduced and the braking effect is improved. There are three common heat dissipation methods, air cooling, water cooling and oil cooling. Because the clearance between the brake drum and the friction plate is small, and the brake drum wraps the friction plate in a large range, a large amount of heat is generated in a short time during braking on a truck with a large carrying capacity, and the heat is difficult to be dissipated through air cooling, and particularly in summer, the weather is hot, and the air cooling effect is poor. Oil cooling is adopted, a few common oil cooling modes are adopted, but the oil cooling has the important defect that once a brake cooling system leaks, some engine oil splashes onto a brake drum and a friction plate on a wheel rotating at a high speed, once the brake drum and the friction plate are soaked with the engine oil, serious influence is generated, the brake drum and the friction plate brake by virtue of friction force, and the engine oil is lubricated, so that the brake system fails, and fatal accidents can be caused. Therefore, water cooling is preferably employed. The water cooling mode is divided into a plurality of modes: the direct water spraying method is characterized in that when braking occurs, a nozzle directly sprays water to a braking system to enable the braking system to be cooled rapidly, the mode has the advantage of rapid cooling, but has great negative effects, firstly, in the water spraying process, water is heated and vaporized to generate a large amount of steam which is emitted to the periphery of wheels, and like flying and cloud driving fog, the sight of a car behind is influenced, and traffic accidents are easy to occur; the biggest negative effect is that water is sprayed on the heating brake drum, so that the physical property of the brake drum is changed, and the brake drum becomes harder and is easy to break. Except for direct water spraying, most of the water is indirectly cooled through various water pipes.
Most of the existing devices are cooled in a single mode, the cooling effect is limited, and in order to improve the cooling effect of the device, a forced air-cooling and water-cooling drum brake is provided, and the cooling mode combining air cooling and water cooling is adopted, so that the cooling effect is improved.
