2. owing to adopt dual-chamber brake, tractor truck and trailer can be braked respectively, when wherein riches all the way life fault, but other one tunnel still normal reliable work, safety performance is better.
3. dual circuit gas-liquid brake system operation of the present utility model is easy, laborsaving, the chaufeur indefatigability.
Description of drawings
Fig. 1 is the structural representation of the utility model dual circuit gas-liquid brake system.
The specific embodiment
Below in conjunction with accompanying drawing and to have three vehicles that save trailers is that specific embodiment describes in detail the utility model.
Fig. 1 is the structural representation of the utility model dual circuit gas-liquid brake system, on the tractor truck wheel, be fixed with the tractor truck brake cylinder, on the first segment trailer wheels, be fixed with first segment trailer braking protection valve wheel cylinder, be fixed with the second joint trailer braking protection valve wheel cylinder on the second joint trailer wheels, be fixed with the 3rd joint trailer braking protection valve wheel cylinder on the 3rd joint trailer wheels.On tractor truck 19, be fixed with air compressor 1, total air receiver 4, tractor truck air receiver 20, barometric regulator 2 and dual-chamber brake 6.On the second joint trailer 15, be fixed with emergency relay valve 11 and trailer air receiver 12.The pressurized air delivery port of air compressor is connected with total air receiver 4 by check valve 3, is connected with tractor truck air receiver 20 by check valve 21.Total air receiver is connected with compression indicator respectively with the tractor truck air receiver.For structure is simpler, compression indicator adopts crosspointer atmospheric pressure table 5, and total air receiver is connected with crosspointer atmospheric pressure table respectively with the tractor truck air receiver.Total air receiver 4 one tunnel is connected with the trailer braking protection valve chamber of dual-chamber brake 6, and the barometric regulator 2 of leading up to is connected with the pressure loosening valve port of air compressor 1, leads up to quick coupling 8 and pipeline to be connected with emergency relay valve 11 on being fixed on second trailer.Tractor truck air receiver 20 is connected with the tractor truck brake chamber of dual-chamber brake 6, and the tractor truck brake chamber of dual-chamber brake is connected with tractor truck air booster pump 18, and tractor truck air booster pump is connected with tractor truck brake cylinder on the tractor truck wheel.The trailer braking protection valve chamber of dual-chamber brake is connected with described emergency relay valve 11 with pipeline by quick coupling, emergency relay valve is connected with the trailer air receiver, emergency relay valve 11 is connected with the air booster pump 10 of first trailer 17, the air booster pump 16 of second trailer 15, the air booster pump 14 of the 3rd trailer 13, the air booster pump of first segment trailer is connected with first segment trailer braking protection valve wheel cylinder, the air booster pump of the second joint trailer is connected with the second joint trailer braking protection valve wheel cylinder, and the air booster pump of the 3rd joint trailer is connected with the 3rd joint trailer braking protection valve wheel cylinder.Pipeline between tractor truck and the trailer quick coupling preferably adopts flexible pipe 9.Emergency relay valve is synchronous emergency relay valve or leading emergency relay valve.The air booster pump can adopt the ZL20 of Wuhu brake valve of car factory, 936E type or Wuhu to contain dynamic braking Co., Ltd SL20-3510002 type air booster pump.Emergency relay valve adopts the ZJ382-11011 of Jiawang Automobile Braking System Manufacturing Co., Ltd. type.
