Embodiment Construction

[0011] Further illustrate the present invention below in conjunction with accompanying drawing:

[0012] as attached figure 1 , figure 2 Shown is an embodiment of a drum brake air cooling device for a truck, including a driving wheel 1, a transmission belt 2, a driven wheel 3, an engagement device 4, a fan 5, an air duct 6, a rear wheel brake 7, and a brake baffle hole 8. Brake shoe 9, nozzle 10, brake drum 11. The driving wheel is installed at the position of the crankshaft pulley, and the driving wheel is manufactured with two transmission belt grooves, which can drive two transmission belts to run at the same time. In order to facilitate replacement, one end of the transmission belt is installed in the outer groove of the driving wheel. The radius of the driven wheel is smaller than that of the driving wheel to form a speed ratio, and the driven wheel transmits power with the driving wheel through a transmission belt. The engaging device is installed between the driven ...

Abstract

The invention relates to a truck drum type braking air cooling device. The device mainly comprises a driving wheel, a driving belt, a driven wheel, an engage switch, a fan, an air pipe and a nozzle, wherein the driving wheel is mounted at a crankshaft pulley position, one end of the driving belt is mounted on an outer side groove of the driving wheel, the driven wheel is less than the driving wheel in radius, the engage switch is mounted between the driven wheel and the fan, the fan is connected with the air pipe, an air outlet of the air pipe is connected with the nozzle through a flexible material, and the nozzle directly faces a gap between a brake drum and a friction plate. According to the device, cooling of a high-temperature brake is achieved in a blowing mode.

Description

technical field [0001] The invention belongs to the technical field of automobile brake cooling, and in particular relates to a drum-type brake air cooling device for trucks. Background technique [0002] Braking is essential for the normal driving of a car, and it is the guarantee of the safety of the vehicle and personal property. The mass of the truck is large, and frequent braking during driving will cause the brake friction to generate high temperature, especially the rear wheel brake. Long-term high temperature will cause the friction coefficient of the brake friction material to decrease, resulting in a decrease in friction and even braking. Failure, is not conducive to safe driving, so brake cooling is particularly important. Limited to the structural characteristics of the drum brake, the traditional method is to cool down the brake drum by spraying water, but the limitation is that the water storage capacity of the water tank is limited, and the amount of water sp...
