It is illustrated in conjunction with specific work process of the attached drawing to hydraulic circuit of the invention:
Under Fig. 4 state, vehicular control unit 14 judges interior someone at this time, and vehicle is travelling, vehicle-mounted control list
Member 14 receives the remote command at user's control end 19, controls 11 quick release of energy of accumulator to hydraulic circuit, works as system pressure
When reducing to a certain extent, pressure switch 12 issues signal, and oil pump 1 is made to start to start, and provides from 10 oil suction of fuel tank to system
Circuit, the second fluid-control one-way are accessed in pressure oil, the right position of 3-position-3-way solenoid directional control valve 8 and 3 left position of three-position four-way electromagnetic directional valve
It is passed through at the control mouth of valve 7 without control pressure, functions as common check valve.At the control mouth of first hydraulic control one-way valve 4
When having control pressure oil, and controlling pressure greater than hydraulic control one-way valve following pressure and the resultant force of spring force, the first hydraulic control one-way valve 4
It connects up and down, pressure oil enters in the rodless cavity of double acting hydraulic cylinder 6 through throttle valve 2, the second hydraulic control one-way valve 7, and piston rod 5 is slow
Slow work to the right is into pressure oil finally flows back to fuel tank 10 through the first hydraulic control one-way valve 4；1 exit of oil pump accesses pilot proportional and overflows
Flow valve 9, the input current of adjustable proportional pressure control valve, i.e., the operating pressure of adjustable hydraulic system, to change piston rod 5
Thrust.
Under state shown in Fig. 5, circuit is accessed in the right position of three-position four-way electromagnetic directional valve 3, at this time 4 phase of the first hydraulic control one-way valve
When in common check valve, the second about 7 hydraulic control one-way valve is connected, pressure oil enters in hydraulic cylinder rod chamber, piston rod 5 slowly to
Left work into.By periodically switching the station of three-position four-way electromagnetic directional valve 3, the reciprocating motion of piston rod 5 can be realized.
Under state shown in Fig. 6, circuit is accessed in the middle position of three-position four-way electromagnetic directional valve 3, by the first hydraulic control one-way valve 4 and the
Two hydraulic control one-way valves 7 constitute bidirectional hydraulic lock, and the first hydraulic control one-way valve 4 and the second hydraulic control one-way valve 7 are equivalent to commonly at this time

Road, when acceleration transducer monitors that the corner acceleration that user steps on the gas is more than given threshold, oil pump 1 and accumulator 11 are simultaneously
To hydraulic oil supply cylinder, making piston rod 5, quickly movement prevents user from continuing to trample throttle.
Under state shown in Fig. 8, oil circuit is accessed in the left position of 3-position-3-way solenoid directional control valve 8, and oil pump 1 is started to work to accumulator
11 fuel feeding make accumulator 11 store energy.When 11 pressure rise of accumulator is to set pressure, pressure switch 12 issues letter
Number, shut down oil pump 1.
The device hydraulic system can reduce improvement cost and be easy in conjunction with anti-lock (ABS) system existing on automobile
It realizes.There are oil pump 1, accumulator 11, pressure switches 12, since automobile generally accelerates and brakes not in anti-lock hydraulic system
It can occur simultaneously, therefore the device is smaller on the influence of original ABS system.Base of the device hydraulic system in original ABS hydraulic system
Two-position two-way electromagnetic directional valve 13 is added on plinth, as shown in Figure 3.Two-position two-way electromagnetic directional valve 13 will be passed through ABS hydraulic system
Oil circuit block, thus make executing agency carry out various operations when do not influence abs braking hydraulic system.When sensor detects vapour
When vehicle wheel is in locking state, two-position two-way electromagnetic directional valve 13 is opened and is in 3-position-3-way solenoid directional control valve 8
Left position, and hydraulic system pressure is adjusted by pilot-operated proportional relief valve 9, ABS system can be made to work normally.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
