The specific embodiment
Brake shoe cooling system embodiment of the present invention, as shown in Figure 1, 2, it comprises brake facing 1, and it also comprises water-cooling system, and water-cooling system comprises radiator, and radiator is fixed on the brake facing 1.Brake facing 1 comprises friction lining 101, steel backing 102, and friction lining 101 is fixed on the face of steel backing 102, and radiator is fixed on another face of steel backing 102.
Radiator is the steel disc 2 with tank 201, and steel disc 2 is provided with water inlet 202 and the water outlet 203 that is communicated with tank 201; Tank 201 is a curvilinear tank, and it is opened on a face of steel disc 2, and pre-subpunch forms on steel disc 2.This face of steel disc 2 sticks on the steel backing 102 by high temperature resistant binder sealing, avoids overflowing of water in the steel disc tank.Steel disc 2 is handled through chromium plating, avoids tank to be lost by scale.
As shown in Figure 3, water-cooling system is for comprising water tank 5, water pump 6, hydraulic pipeline 3, radiator; Water-cooling system provides power by water pump 6; Water tank 5, hydraulic pipeline 3, radiator form water-flow circuit.Water inlet 202 and water outlet 203 are communicated with the hydraulic pipeline 3 of water-cooling system.What hydraulic pipeline 3 adopted is the high-temperature resistant rubber pipe, avoids under the high temperature of brake facing fusing or distortion and causes the damage of circulation waterway to be lost efficacy.Water tank 5 can be fastened on the vehicle frame with steel band.Water 7 in the water tank 5 enters water pump 6 by filtering net 8.
Water-cooling system also comprises the temperature sensor 4 that is used to measure brake facing 1 temperature.Have the hole on the brake facing 1, temperature sensor 4 is the needle-like temperature sensor, in temperature sensor 4 embedded holes.Wearing and tearing thickness when the distance of the needle point of needle-like temperature sensor and friction lining 101 end faces is scrapped greater than friction lining 101, as close as possible friction lining 101 end faces of needle point, thus guarantee that the sensor measured temperature reflects friction lining 101 surface temperatures substantially.
As shown in Figure 4, water-cooling system comprises temperature sensor 4, the controller that is used to measure brake facing 1 temperature; The mouth of temperature sensor 4 is connected with controller; Water pump 6 is controlled by controller.
Controller comprises amplifying circuit, comparator circuit, relay and driving circuit thereof.Brake facing 1, temperature sensor 4, controller, water pump 6, water-flow circuit form a closed loop control system.
As shown in Figure 5, temperature sensor 4 is transformed into faint electric signal with temperature signal, carries out processing and amplifying through amplifying circuit.Electric signal after the amplification compares processing through comparator circuit, and what comparator circuit adopted is the hysteresis comparator circuit, as shown in Figure 6.Ui is an input voltage signal, also is the output of upper class amplifying circuit; Ur is a reference voltage, is to determine according to the temperature upper limit of brake facing normal operation, by calibration, equates with output voltage under the synthermal value of temperature sensor.When Ui＜Ur, be output as low level; When temperature build-up, Ui increase to greater than Ur, be output as high level; Temperature falls after rise when being lower than Ur, and low level is then got back in output.
Add emitter-follower at comparator output terminal, as shown in Figure 6, increase the on-off action of outgoing current with control relay, and then the startup of control water pump and stopping.
The principle of work of the embodiment of the invention is: in the process of chaufeur brake, temperature sensor keeps the monitoring to the brake facing temperature constantly, if brake overlong time or brake load is excessive on the ramp causes the brake facing temperature to surpass predefined normal operation temperature limitting T
N, comparator circuit can be exported high level, drives relay closes through incremental processing, and the water pump unlatching constantly is sent to each brake facing in a steady stream with cooling water expansion tank they is cooled off.Recover normal when sensor to the brake facing temperature, promptly be lower than T
N, comparator circuit meeting output low level, the relay outage disconnects, and water pump stops pump water, and cooling circulation stops.
Complexity and the brake load of considering structure mainly concentrate on trailing wheel, can only on vehicle rear wheel, adopt brake shoe cooling system of the present invention, have only a tank on the whole vehicle, hydraulic pipeline 3 can adopt four manifolds in parallel with four brake facing 1 intake-outlet sealings of two drgs.In order to guarantee that each brake facing all has better cooling effect, water pump 6 adopts the high-voltage electric water pump, by vehicle-mounted 12V storage battery power supply.
For all drgs on the car, only need a slice brake facing mounting temperature sensor in the trailing wheel.By ball bearing made using sensor signal is handled, and control cooling system unlatching or close.
Brake shoe cooling system of the present invention, it also can adopt tubular radiator.Radiator also can be fixed on the back side of friction lining 101.The temperature sensor 4 that is used to measure brake facing 1 temperature also can be infrared temperature sensor.
