Problems solved by technology

But because its water spray device is outside the brake drum, the disadvantage is that dust can easily enter the cooling channel, which makes it more difficult for the cooling water to enter the cooling channel, which will eventually cause high temperature water and steam to transfer heat pass to the wheel
Therefore it is only suitable for use on brakes with narrow friction linings

Abstract

The invention provides a water-cooled vehicle brake, which includes a wheel hub installed on the car, a brake drum arranged on the car and the wheel hub, an inner dust cover arranged in the brake drum and fixed on the car, and The water jacket and reinforcing hoop outside the brake drum are arranged at intervals between the axial ribs in the water jacket and the evaporative cooling channels between adjacent ribs, which are characterized in that there is an evaporative cooling channel between the brake drum and the hub. The inner water chamber connected by passage, the water delivery pipe is fixed on the inner dustproof cover, and the spray nozzle at its end is placed in the inner water chamber. Cooling water can be provided from the inside of the brake drum to the outside to fully cool the brake drum. While the brake drum is effectively cooled, the utilization rate of cooling water is improved, water is saved, and the temperature rise of the brake and friction plates is avoided. The service life of the brake and the friction plate is prolonged, the brake drum is prevented from cracking, and the transportation cost is reduced. The structure is simple, the work is stable and reliable, and the thermal stability is good.

Description

technical field [0001] The invention relates to a vehicle brake device, in particular to a water-cooled vehicle brake, and belongs to the technical field of vehicle brake device design and manufacture. Background technique [0002] In traditional vehicle braking devices, most of the heat generated by friction during braking is transferred to the brake drum, which increases the temperature of the brake drum, and eventually causes the brake drum to increase the brake clearance due to thermal expansion. Therefore, in order to reduce the heat generated by braking and make the brake drum have a larger heat capacity, it is usually to make the brake drum have a large enough mass, and even set some ribs or add reinforcement hoops on the outer surface of the brake drum to increase the heat capacity of the brake drum. The heat dissipation capacity and strength of the brake drum. However, for vehicles traveling in mountainous areas, since the brakes are in the braking state for a long...
