Description
[technical field]
The present invention relates to automobile braking cooling systems, and in particular to automobile wet-type brake external circulation cooling system.
[background technique]
The working principle of existing automobile wet-type brake system is to utilize the non-rotation being connected with vehicle body (or vehicle frame)
Turn the phase mutual friction between element and the rotating element being connected with wheel (or transmission shaft) to prevent the rotation or rotation of wheel
Trend.When driver depresses brake pedal, and piston is made to compress brake fluid, wheelcylinder piston is under the action of hydraulic by shoe brake
It presses to brake drum and forms frictional force, frictional force makes brake drum reduce velocity of rotation, or remains stationary.
At work, the heat that brake(-holder) block friction generates rises brake temperature to brake, due to brake oil
Chamber closing, brake temperature constantly increase, braking ability will be made to decay when temperature is excessively high, and influence traffic safety.
It is learnt from the retrieval to the relevant technologies, current existing external circulation cooling system, power source is derived from drive axle
Main reducing gear rotates the fan work for driving oil pump and radiator by Driven Gear of Final Reduction Gear, to realize external circulating system
The refrigerating function of flowing and radiator.But there are some disadvantages for the technical solution.Firstly, external circulating system power source is derived from
The main reducing gear of drive axle, since in vehicle travel process, with the stopping that starting to of vehicle, the revolving speed of drive axle is mutually strained
Change, in the state that drive axle revolving speed is extremely low and stops, external circulating system stops working, cannot continuously cool down to brake,
Secondly, the fan of radiator is from main reducing gear of drive axle gear power taking, drive axle revolving speed, which constantly changes, prevents fan from stabilization
Revolving speed under work, influence cooling effect.Finally, the prior art is to need from main reducing gear of drive axle gear power taking in axle housing
Inside increases transmission device, and processing technology is complicated, and cost of implementation is higher.
Therefore, now with outer circulation cooling technology cannot to brake carry out continuous-stable cooling, and cost compared with
It is high.
