Vehicle-bridge automatic water-cooling apparatus

Abstract

The invention relates to an automatic water cooling device of a vehicle bridge, belongs to an automobile accessory, and in particular relates to a vehicle bridge cooling device. The device comprises a vehicle water tank; and a water pipe is respectively connected with the water tank and a nozzle. The vehicle bridge cooling device is characterized in that an electromagnetic valve is arranged on the water pipe; one end of the electromagnetic valve is connected with the water tank; the other end of the electromagnetic valve is connected with the nozzle; the nozzle is fixed on a vehicle bridge dustproof hood and faces towards a brake drum; a temperature sensor is fixed on a vehicle axle in the brake drum of the vehicle bridge; the temperature sensor is externally connected with an amplifying circuit; and the amplifying circuit is connected with the electromagnetic valve. When the temperature of the vehicle bridge is abnormal, the electromagnetic valve is automatically opened, and water is injected out for cooling; and when the temperature is normal, the electromagnetic valve is automatically closed. The vehicle bridge cooling device has the advantages of novel concept, simple and reasonable structure, easy processing and convenient maintenance, can accurately detect the temperature of the brake drum of the vehicle bridge and a bearing in time, cool the vehicle bridge in time when the temperature is abnormal, effectively avoid the faults that the bearing is burned down, a brake is out of order and a tire is blown out caused by abnormal temperature of the vehicle bridge and ensure safety of vehicle driving.

Description

technical field [0001] The invention belongs to auto parts, in particular to an axle cooling device. Background technique [0002] When the vehicle is running, the temperature of the bearing is often too high due to lack of oil, damage or tight clearance of the bearing, which causes the bearing to burn out; the long-term braking of the vehicle during the long-distance downhill process will cause the temperature of the brake drum to increase. Too high, resulting in bearing burnout, brake failure, tire burst and other failures. The generation of these faults makes car owners have to pay huge towing fees and maintenance fees, which not only affects the smooth flow of roads, but even leads to traffic accidents involving car crashes and fatalities. In order to avoid the occurrence of such accidents, some drivers usually stop and check every few hours. If the temperature of the axle can be found to be too high in time, they will be cooled with water; When the axle temperature is...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the driver cannot find the abnormal change of the axle temperature in time to implement cooling. Usually, the driver finds that the axle temperature is too high after the axle has been burnt out, but it is too late
