[0002] The brake drum is an important part of the braking system of trailers, semi-trailers or heavy-duty vehicles. The performance of the brake drum directly affects the braking performance of the vehicle and has a crucial impact on the safety performance of the vehicle. However, the inherent The problem has always existed. The existing brake drum is made of gray cast iron, which is easy to machine, wear-resistant, and has a large heat capacity, but at the same time, gray cast iron has low strength and high brittleness, and there is no automatic cooling device inside the brake drum. When the drum is in use, some air-cooling or water-cooling methods are used to cool down, but the cooling effect is not obvious. When the temperature inside the brake drum rises sharply during braking, the high heat cannot be dissipated in time, which greatly affects the The service life of the brake drum, and the above-mentioned cooling system needs to be driven by external force, which increases the energy consumption of the vehicle

The invention relates to an intelligent cooling device for a brake system of a trailer, which belongs to the technical field of brake systems and includes a brake drum, a brake cover and brake shoes installed on the brake cover. A cooling chamber is arranged in the wall of the brake drum, and a There are liquid inlet pipe and liquid outlet pipe, the liquid outlet pipe is connected to the inlet of the heat exchanger through the oil return pipe, the outlet of the heat exchanger is connected to the oil storage tank through the first connecting pipe, and the oil storage tank is connected to the oil pump through the second connecting pipe. The inlet is connected, the outlet of the oil pump is connected with the inlet pipe through the oil inlet pipe, the oil pump is installed on the back of the brake cover, the rotating shaft of the oil pump extends into the brake drum, and the friction wheel assembly is installed on the rotating shaft of the oil pump. The inner walls of the brake drum are in contact with each other, driving the oil pump to rotate, so as to circulate the cooling oil in the cooling chamber. The invention is simple in structure, easy to use, does not need external force to cool the brake drum, and has a good cooling effect.
