Concrete working process of the present invention is as follows:

One, braking accumulation of energy process: after depressing automobile brake pedal, after controlling ECU (Electrical Control Unit) of the present invention and receiving the signal of brake pedal position sensor, connect three circuit:

Article one, circuit is connected, make electromagnet 1.8 energisings with the automatically controlled two-way needle roller power-transfer clutch 1 of the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 bonded assemblys, pulling armature 1.6, insert circle 1.7, make conical surface applying (ring washer 1.9 transfixions before this of the conical surface of inserting circle 1.7 and ring washer 1.9, insert the circle 1.7 wind spring hooks that are engaged on the gear 1.2 in-to-in clutch outer 1.3 and rotation), friction force after the applying overcomes the slotting circle 1.7 of elastic force of wind spring and stirs 22 needle rollers 1.4 to the rotation of wind spring elastic force opposite sense, causes clutch outer 1.3, needle roller 1.4, input shaft 1.1 combines.Simultaneously, the transmission of power of automobile is given the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2, make pivot shaft 2.5, cylinder body 2.11, plunger 2.8, ball pivot 2.7, platen 2.6, swash plate 2.3, swash plate base worm gear 2.1 inner rotation that coexist, because swash plate base worm gear 2.1 has certain pivot angle with worm screw 2.2 engagements and with axis, so plunger 2.8 is also done axially reciprocating in rotational in swash plate base worm gear 2.1, the volume in the plunger sleeve bucket 2.9 is constantly changed.Volume when plunger 2.8 rotates in the plunger sleeve bucket 2.9 increases the oil suction chamber suction of hydraulic oil through thrust plate 2.4, and the volume when plunger 2.8 upwards rotates in the plunger sleeve bucket 2.9 reduces hydraulic oil is discharged through the oil pocket that goes out of thrust plate 2.4.

The second circuit is connected, and connects the solenoid circuit of the two-position three way direction valve 3.7 on the cover plate 3.6 that covers fuel-return valve 3.3.The oil pocket at fuel-return valve 3.3 spring places is communicated with B place oil pocket, because B place oil pocket is higher than the pressure of T place, fuel-return valve 3.3 back side oil pocket from the hydraulic oil of fluid storage tank 8 oil outlets from the pressure of the hydraulic oil of the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 oil outlets, so fuel-return valve 3.3 upwards is close to the fuel-return valve of valve plate 3.1, valve seat is in closed condition.This moment, the hydraulic oil of B place oil pocket was pushed the P place oil pocket that delivery valve 3.4 enters connection energy storage 4 hydraulic fluid ports open.The hydraulic oil of the A place oil pocket that is communicated with the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 oil inlets is simultaneously siphoned away by the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2, the pressure of A place oil pocket is lower than the pressure of T place oil pocket, so the hydraulic oil of the T place oil pocket that is communicated with fluid storage tank 8 oil outlets is pushed the oil inlet that inlet valve enters the axial worm gear pair variable piston of the automatically controlled diclinic dish of A place oil pocket supply motor 2 (reason is that the two-position three way direction valve 3.7 that covers on the cover plate 3.6 of inlet valve 3.2 is in the state of connecting A place's oil pocket and inlet valve spring place oil pocket) open.

Article 3, circuit is connected, and then is the square wave digital circuit of the stepping motor of the axial worm gear pair variable piston of the automatically controlled diclinic dish of control motor 2 variablees.As shown in Figure 3, stepping motor rotates and makes worm screw 2.2 drive 2.1 swings of swash plate base worm gear, the size of its pivot angle is directly proportional with the depth degree that automobile brake pedal steps down, and brake pedal steps down darker, and the pivot angle of swash plate base worm gear 2.1 is just big, the axial stroke of plunger 2.8 is increased, the oil drain quantity of the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 and then increases, and its power, moment of torsion also increase synchronously, causes the braking force of automobile to strengthen, promptly utilize energy, helped brake.Otherwise when lowering brake, the braking force of automobile reduces, and automobile braking force increases, subtracts and increase and decrease with the axial worm gear pair variable piston of automatically controlled double plate motor 2 oil drain quantities.

Two, the vibrational energy collection process: automobile in the process of moving, failure of oscillation is moving for wheel because the road surface fluctuating is constantly jolted vehicle body, automobile is being turned, braking, the vehicle body posture changes during acceleration, the high pressure damper 5 of the tension and compression that these situations all can not stopped, as shown in Figure 6, make piston 5.4 motion vertically in cylinder bucket 5.2, therefore change the volume of cylinder bucket 5.2 inner carriers 5.4 both sides, when the volume in piston 5.4 left sides strengthens, unidirectional oil inlet by high pressure damper 5 replenishes hydraulic oil, the volume on piston 5.4 right sides reduces simultaneously, the unidirectional oil outlet of the high pressure damper 5 of hydraulic oil process is pressed into energy storage 4, thereby these kinetic energy are converted into elastic potential energy, make vehicle vibration damping simultaneously.The volume on piston 5.4 right sides strengthens thereupon when the volume in piston 5.4 left sides reduces, and hydraulic oil enters piston 5.4 right sides through logical oil circuit line as shown in Figure 6.

Three, the process that releases energy: behind the automobile brake off (non-braking mode), the driver to put one's foot down.Controlling ECU (Electrical Control Unit) of the present invention receives and connects two circuit behind the pressure signal in the signal of accelerator pedal position sensor and the energy storage that electro connecting pressure gauge 6 sends 4: as shown in Figure 5, article 1, circuit is connected the solenoid circuit of the two-position three way direction valve 3.7 on the cover plate 3.6 that covers draining valve 3.5.The oil pocket of draining valve 3.5 spring sides is communicated with the A place oil pocket that the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 oil inlets are communicated with.Because the pressure of A place oil pocket is lower than the pressure of the P place oil pocket identical with energy storage 4 hydraulic fluid ports at this moment, the pressure that draining valve 3.5 left end step surfaces are subjected to is greater than the elastic force of draining valve 3.5 right-hand member springs, and draining valve 3.5 is opened.Hydraulic oil in the energy storage 4 enters the oil inlet of the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2.Enter and the corresponding plunger of the oil suction chamber of thrust plate 2.4 2.8 bottoms through the oil suction chamber of thrust plate 2.4 and the oil duct of axle 2.5 as Fig. 4, hydraulic oil shown in Figure 3, make plunger 2.8 utilize ball pivot 2.7, swash plate 2.3 and bearing axial push swash plate base worm gear 2.1.Because swash plate base worm gear 2.1 has certain pivot angle, plunger 2.8 produces tangential component and stirs cylinder body 2.11 and axle 2.5 rotations when being subjected to axial reaction force, drives the input shaft 1.1 of automatically controlled two-way needle roller power-transfer clutch 1.This moment, two automatically controlled two-way needle roller power-transfer clutchs 1 played the free-wheel clutch effect shown in Fig. 2 a, utilized engaging gear 2.2 that transmission of power is driven running car to propeller-shaft, made energy obtain utilizing again.The oil outlet of the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 is communicated with the B place oil pocket of multidirectional many logical multidigit electro hydraulic valves 3, as shown in Figure 5, this moment, hydraulic oil pressure herein was higher than the pressure of the oil pocket of the fuel-return valve 3.3 spring sides that are communicated with T place oil pocket, the pressure that fuel-return valve 3.3 upper end step faces are subjected to is greater than the elastic force of fuel-return valve 3.3 lower end springs, fuel-return valve 3.3 is opened, and hydraulic oil flows back to fluid storage tank 8.

Article 2, circuit then is the square wave digital circuit of the stepping motor of the axial worm gear pair variable piston of the automatically controlled diclinic dish of control motor 2 variablees.As shown in Figure 3, stepping motor rotates and makes worm screw 2.2 drive 2.1 swings of swash plate base worm gear, the size of its pivot angle is directly proportional with the depth degree that the car acceleration pedal steps down, acceleration pedal steps down darker, the just big tangential forces that plunger 2.8 is produced of the pivot angle of swash plate base worm gear 2.1 increase, the moment of torsion of the axial worm gear pair variable piston of automatically controlled diclinic dish motor 2 also increases synchronously, and is the same with the reason that causes automobile brake to strengthen, and causes the tractive force of automobile to strengthen.Otherwise the tractive force of automobile reduces, and makes tractive force obtain utilizing.

Four, realize the no driving engine driving process that ' leads resistance ': automobile in the process of moving, when the driver lifts acceleration pedal and makes the driving engine rev down shown in Fig. 2 b, automatically controlled two-way needle roller power-transfer clutch 1 plays the free-wheel clutch effect at this moment, engaging gear 1.2, clutch outer 1.3, needle roller 1.4, insert circle 1.7, around input shaft 1.1 idle running, so the automobile kinetic energy impassabitity change speed gear box that the transmission shaft transmission comes is passed to driving engine, thereby driving engine can not lead the resistance running car, reduced the resistance to motion of automobile, realized that no driving engine leads resistance, also promptly realized the utilization again of energy.

Beneficial effect of the present invention is, this device converts vehicle body braking and vibrational energy to hydraulic pressure and can be stored in the energy-storing device, reaches available purpose, and its effect is obvious, and driving engine can not lead travelling of resistance automobile simultaneously, has also reduced automobile running resistance.
