Background technology
Current service braking system is mostly adopted the brake pedal that tramps with one's feet and is realized braking, and driver drives vehicle needs first M/C forward-reverse gear, then pin step on the accelerator, when braking, need unclamp Das Gaspedal, step on brake pedal, manual reverse of direction is to meta (N) shelves, for long continuous operation, short range travels, the chaufeur of frequent operation throttle and gearshift, and this operating mode is easy to make people tired, work efficiency is low, and vehicle life span is short.Along with the progress of science and technology, chaufeur requires more and more higher to operation comfort and work efficiency, and said system can be eliminated gradually.
Summary of the invention
The technical problem to be solved in the present invention is: for above-mentioned Problems existing, provides the service braking system that a kind of structure is simple, easy to operate, to simplify brake operating flow process, increases work efficiency, and extends vehicle life span.
The technical solution adopted in the present invention is: a kind of service braking system, is characterized in that: have energy storage, brake activation valve, reducing valve, electromagnetic valve, controller and drg, and is the hydromechanical system of energy storage topping up,
Described energy storage is through the inlet II of brake activation valve and pipeline connection electromagnetic valve, and energy storage is through the inlet I of reducing valve and pipeline connection electromagnetic valve, and the liquid outlet III of electromagnetic valve is communicated with drg by the road;
Described controller receives Das Gaspedal and to enter into depth signal, and this controller be electrically connected the pressure sensor be placed in brake activation valve inlet, and described controller is electrically connected electromagnetic valve, and the liquid outlet III of Controlling solenoid valve connects inlet I or the inlet II of electromagnetic valve.
Described hydromechanical system comprises fuel tank, and this fuel tank is communicated with described energy storage through oil absorption filter, oil pump and prefill valve successively.
The invention has the beneficial effects as follows: 1, service braking system becomes Dual-path brake system, safety and reliability from former single channel brake system.2, former vehicle driving system and service braking system troublesome poeration, efficiency is low, and service braking system of the present invention possesses the control system of higher automatization level, when unclamping Das Gaspedal, can automatic train stop; In driving in case of emergency, step on urgent pedal, can emergency brake be completed.Two cover systems cooperatively interact, and automatically regulate, and more simply, efficiency is high, and cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment.
Detailed description of the invention
As shown in Figure 1, the present embodiment has hydromechanical system, energy storage 5, brake activation valve 6, electromagnetic valve 8, controller 10, Das Gaspedal 9, reducing valve 7 and drg 11.Wherein hydromechanical system comprises fuel tank 1, oil absorption filter 2, oil pump 3 and prefill valve 4, and fuel tank 1 is communicated with energy storage 5 through oil absorption filter 2, oil pump 3 with prefill valve 4 successively.
Energy storage 5 is communicated with 1 mouthful of brake activation valve 6 through oil pipe, and 2 mouthfuls of brake activation valve 6 are communicated with fuel tank, and 3 mouthfuls of brake activation valve 6 are communicated with the inlet II of electromagnetic valve 8, and brake activation valve 6 has brake pedal, is controlled 3 mouthfuls of 1 mouthfuls or 2 mouthfuls of connecting on it of brake activation valve 6 by brake pedal.Energy storage 5 is communicated with the inlet I of electromagnetic valve 8 through oil pipe, reducing valve 7, and the liquid outlet III of electromagnetic valve 8 is communicated with drg 11.This routine middle controller 10 (model: DL300-702000-000, producer: Science and Technology Ltd. is helped in Linan ten thousand) be electrically connected the pressure sensor (SUCO model 0166411043044) be placed in 1 mouthful of brake activation valve 6, receive the pressure information in brake activation valve 61 mouthfuls, and after being communicated with 3 mouthfuls of brake activation valve 6 at 1 mouthful of brake activation valve 6 (1 mouthful of internal pressure of brake activation valve 6 changes), controller 10 Controlling solenoid valve 8 must not be electric, and the inlet II of electromagnetic valve 8 is communicated with the liquid outlet III of electromagnetic valve 8; Controller 10 receives Das Gaspedal 9 and to enter into depth signal, and when Das Gaspedal 9 is positioned at initial position Controlling solenoid valve 8 electric, the inlet I of electromagnetic valve 8 is communicated with the liquid outlet III of electromagnetic valve 8.
The principle of work of the present embodiment is as follows:
Filling process: when the hydraulic fluid pressure low pressure driving brake-pressure that energy storage 5 stores, prefill valve 4 starts topping up, the hydraulic oil that now fuel tank 1 stores is drawn onto prefill valve 4P mouth through oil absorption filter 2 by oil pump 3, fluid provides enough pressure oil-sources after prefill valve 4, is stored in energy storage 5 does energy source for service braking system by prefill valve 4B mouth.Now oil pump provides unnecessary oil through the N mouth oil sump tank 1 of prefill valve 4.That drg 11 stores or the liquid outlet III of pressure oil in electromagnetic valve 8 that do not discharge completely, then in brake activation valve 63 mouthfuls and 2 mouthfuls get back to fuel tank 1, in this process, brake activation valve 6 is in the position shown in meta state and Fig. 1.
Vehicle is normally driven a vehicle non-braking state: the hydraulic oil that one, energy storage 5 stores is sealed in pressurize in this oil circuit by prefill valve 4, brake activation valve 6 and electromagnetic valve 8; Two, oil pump 3 provides unnecessary oil through the N mouth oil sump tank of prefill valve 4; Three, pedal 9 is stepped on the throttle containing left-hand tread plate working direction, right-hand tread plate direction of retreat, the degree of depth via controller 10 of pedal processes change speed gear box and controls the forward-reverse of vehicle and the speed traveling of vehicle, in this process, two pedal 9 signal via controller 10 must not be electric to electromagnetic valve 8 place after processing, be in normally off, the hydraulic oil in this process in energy storage 5 is in packing state.
Vehicle normally drive a vehicle in brake process: unclamp advance in Das Gaspedal 9 or retreat pedal, after now the depth signal via controller 10 of entering into of Das Gaspedal 9 processes, electromagnetic valve 8 obtains electric, energy storage 5 store oil through reducing valve 7 to the inlet I in electromagnetic valve 8, electromagnetic valve 8 obtains electric rear inlet I and communicates with liquid outlet III, and fluid, realizes unclamping two pedal to drg 11 through electromagnetic valve 8, automatic brake functions, wherein reducing valve 7 is pressure functionals of regulating brake.
Emergency brake process in vehicle driving: the brake pedal stepping on brake activation valve 6, oil now in energy storage 5 is switched to 3 mouthfuls of brake activation valve 6 through 1 mouthful of brake activation valve 6, after 1 mouthful of place of brake activation valve 6 has individual pressure sensor via controller 10 to process, Controlling solenoid valve 8, make electromagnetic valve 8 must not electricity, the oil that brake activation valve is 63 mouthfuls to the liquid outlet III of electromagnetic valve 8 through the inlet II of electromagnetic valve 8, finally flow into drg 11, completes emergency brake.
