Description of the drawings
The content of every width attached drawing expression in the utility model specification is briefly described below：
Fig. 1 is Reservoir Charge-Up valve reliability test system block diagram.
Specific implementation mode
Full-hydraulic braking apparatus component reliability Bench Test System.Using motor as power source, gear pump drives as pressure
High pressure oil is inputted Reservoir Charge-Up valve, Reservoir Charge-Up is given, as the input pressure source of hydraulic brake valve, electricity consumption by dynamic device
Control device control hydraulic brake valve pedal is reciprocating, actual condition when drive simulating person tramples, and brake valve oil outlet is defeated
Go out high pressure oil, driving brake moves back and forth；The test method, low energy consumption, does not pollute working environment, experimental rig structure essence
Really, failure rate is low.
As shown in Figure 1, motor is connected by hydraulic pump with Reservoir Charge-Up valve oil inlet, prefill valve oil outlet and accumulator
Oil inlet is connected, while being connected with hydraulic brake valve oil inlet, and hydraulic brake valve oil outlet is connected with brake.Control circuit：
Motor drive mechanism is connected with hydraulic brake valve pedal, pushes piston and implements output hydraulic pressure.
Motor is connected with hydraulic pump, then is connected with overflow valve, filter, passes through high-pressure hose and Reservoir Charge-Up valve oil inlet
Mouth is connected, and two oil outlets of prefill valve are connected with two accumulators respectively, while being connected with two oil inlets of hydraulic brake valve, liquid
Pressure brake valve oil outlet is connected with brake oil inlet；Control circuit：Computer switch board is connect with motor drive mechanism, passes through motor
Structure drives brake pedal to make movement in a curve, controls the up and down motion of hydraulic braking valve piston.
High pressure oil from hydraulic pump enters inside Reservoir Charge-Up valve, by the reciprocating motion of piston, exports high pressure oil
Into accumulator and hydraulic brake valve oil inlet；Computer switch board drives brake pedal to make continuous fortune by drive motor structure
It is dynamic, hydraulic brake valve valve port is opened, high pressure oil enters brake by hydraulic brake valve；After continuous movement several times, in accumulator
Pressure drop to after setting value and maximum set pressure can be charged to by prefill valve.
System Working Principle：High pressure oil enters inside Reservoir Charge-Up valve, by the reciprocating motion of piston, in internal system
A balance system is established, the opening and closing of accumulator valve port can be controlled, to control the upper and lower bound of setup pressure value；
Control piper：Computer switch board is to motor mechanism output drive signal so that pedal rotating mechanism takes pedal to, and to make camber line reciprocal
Movement, when pedal depression piston for brake valve, the high pressure oil of output enters brake, when pedal return, in brake and pipeline
Hydraulic oil fuel tank is returned to by hydraulic brake valve, after ring 6-7 times of so escaping, the pressure in accumulator can drop to setting lower limit
It is worth, at this moment prefill valve can open accumulator oil inlet valve again, start filling liquid, stop filling liquid, high pressure after reaching setting upper limit value
Oil realizes the reliability test of Reservoir Charge-Up valve by addition exporting into next system, such circulation action.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as using the methodology of the utility model and various unsubstantialities that technical solution carries out change
Into, or it is not improved the design of the utility model and technical solution are directly applied into other occasions, in the utility model
Protection domain within.
