Hydraulic oil.
Below in conjunction with accompanying drawing, the concrete operating principle of the present invention and process are illustrated.
In conjunction with Fig. 2,3,4, throttle drawstring is placed at position 2.In position shown in Fig. 2, vehicle is in complete on-position,
Return line 40 is in cut-off state, and 20 about two cavitys of master cylinder are obstructed, the spring-compressed gesture being stored by energy-storage units 30
Energy storage piston 32 can be promoted to move right so that the hydraulic oil of master cylinder 20 right side cavity enters brake oil cylinder through oil circuit 51 and makes
Dynamic oil cylinder 50, makes vehicle brake.When stepping on pedal 10, piston 22 is moved to the left, as shown in figure 3, return line 40 still in cut
Only state, the left and right two chambers of master cylinder 20 are obstructed, and the hydraulic oil in master cylinder 20 left side is pressed into energy-storage units 30, promotes and stores
Can piston 32 rise, spring 33 is compressed, the energy of energy storage piston 32 increases, master cylinder 20 right chamber space becomes big, braking
The hydraulic oil that oil cylinder 50 gushes flows to master cylinder 20 right chamber, so that brake weight is diminished.In this process, if energy storage piston
32 diameter is much larger compared with the cylinder diameter of master cylinder 20 or when rigidity of spring 33 is less, spring 33 is applied to the pressure of master cylinder 20
Power varies less, and the reaction force change of pedal 10 is less or has become greatly.With moving to left of piston 22, energy-storage units 30
Entrance aperture is less and less, and the translational speed of piston 22 starts to be restricted, will close when the entrance of energy-storage units 30 and

20 about two cavitys pass through return line 40 UNICOM, and the resistance of at this moment piston 22 movement is basically the resistance of return line 40
Power, by adjusting choke valve 41, can control the speed of piston 22 movement.At this moment brake weight is wholly absent, and piston rod 21 starts
The control of throttle, but still should keep idling in this section of stroke range.The movement of pedal 10 only needs to the power of very little.Continue
Step on pedal 10, enter acceleration area, this section of energy-storage units 30 still remain turned-off, return line 40 UNICOM, and piston 22 is basic
On be not pushed to accelerator open degree by resistance, realize engine accelerate.During advancing whenever, loosen pedal 10, make
Obtain piston 22 to move right, this process of realizing slowing down-braking.When again accelerating, then step on pedal 10.
The position of pin corresponding with this device and leg is：It is lifting status in the complete on-position leg in position 1, now
The gravity of leg is born completely by guide rod, simultaneously need to applying certain active force pedaled stretch, can improve larger pedal 10.
Because leg weight is basically unchanged during depressing, just provide a kind of size substantially constant active force.To idle speed zone
Domain, heel lands, and now because the caliber of return line 40 limits, rapidly depresses motionless, needs a bit of time
Left and right cavity pressure balance Deng master cylinder 20 just can depress, it is to avoid steps on fast state it is ensured that steadily from braking state one pin
Find idle speed zone.Speed at master cylinder 20 balance can be controlled by the aperture of choke valve 41.Master cylinder 20 about cavity pressure
