An intelligent cooling device for an automobile brake drum belongs to the technical field of automobiles. According to an existing wheel cooling method, a gate valve is unscrewed with hands, and water is sprayed on an outer tire of a wheel. According to the device, a temperature sensor is arranged in the brake drum, when the temperature in the brake drum is too high, the temperature sensor outputs a signal, an electronic controller obtains the signal and sends instructions to an electromagnetic switch 1, an electromagnetic valve and an electromagnetic switch 2 respectively, a fan rotates to feed air into the brake drum for cooling, an electromagnetic valve plunger moves to open the a channel, and a booster pump conveys water to the brake drum, the hub and the steel ring to cool the brake drum, the hub and the steel ring. When the temperature in the brake drum is reduced to a certain value, the sensor outputs a signal, the electronic controller obtains the signal and sends an instruction to the electromagnetic switch 1, the electromagnetic valve and the electromagnetic switch 2, the power supply of the fan is cut off, and the fan stops working, and the power supply of the booster water pump is cut off to stop cooling the brake drum, the hub and the steel ring. The device is mainly suitable for large and medium-sized automobiles.
汽车刹车鼓智能降温装置属于汽车技术领域。现有的车轮降温方法是:用手拧开闸阀,水淋到车轮外胎上。本装置在刹车鼓内设置温度传感器,当刹车鼓内的温度过高时温度传感器输出信号,电子控制器获取信号,向电磁开关1、电磁阀和电磁开关2分别发出指令。风机转动,把空气送入刹车鼓内降温。电磁阀柱塞移动,打开水路通道。加压水泵把水输送到刹车鼓、轮毂和钢圈上使其降温。当刹车鼓内的温度降到一定数值时,传感器输出信号,电子控制器获取信号,向电磁开关1、电磁阀和电磁开关2发出指令,切断风机电源风机停止工作。切断电磁阀电源关闭水路通道,切断加压水泵电源停止对刹车鼓、轮毂和钢圈降温。本装置主要适用于大、中型汽车。
