The specific embodiment

Hold technical scheme the supplemental instruction once concrete structure and the principle of work of native system below in conjunction with Fig. 1 and Fig. 2;

As shown in Figure 1, operator is connected to one (1) and rotary center rotary part to hole double fluid liquid switch (10), turn to the connecting lever (2) and the ectosome of switch (10) to be connected to one, drag link (7) flexibly connects spindle arm (6) and turns to connecting lever (2).Structure shown in Figure 1 is that the post action handle type also can be preposition with the same operating system of existing steering wheel steering swivel system in actual needs, and principle of work is identical.The mouth of Hydraulic Pump in Fig. 2 (14) is communicated with aperture (20) with high pressure consistent lubricant pipe (11) through high pressure oil storage bottle (15), and aperture (17) are communicated with the input end of Hydraulic Pump (14) through oil return pipe (12), petrol storage tank (13).Aperture (21) and aperture (16) are through the left hydraulic pressure storehouse of high pressure consistent lubricant pipe (8) connection two-way cylinder (3), and aperture (19) and aperture (18) are communicated with the right hydraulic pressure storehouse of two-way cylinder (3) through high pressure consistent lubricant pipe (9).

The principle of work of wushu operating system is; In driving a vehicle as can be seen in conjunction with Fig. 1, Fig. 2 A point and B point to the time rotary to each aperture in the hole double fluid liquid switch (10) all be in closed condition, two-way cylinder (3) maintains static, vehicle keep straight on or by certain turning half through walking.Rotate counterclockwise operator during turnon left (1), the A point is relative with the C point, aperture (20) and aperture (21) are open-minded, aperture (16) is closed, high pressure oil is through high pressure consistent lubricant pipe (8), flow to the left hydraulic pressure storehouse of two-way cylinder (3), aperture (17) and aperture (18) are open-minded, aperture (19) is closed, oil return pipe (12) is communicated with formation through the right hydraulic pressure storehouse of high pressure consistent lubricant pipe (9) and two-way cylinder (3) and refluxes, two-way cylinder (3) pushes away to the right, intermediate rod (4) and spindle arm (6) drive steering wheel (5) and turn left, because drag link (7) is connecting spindle arm (6) and is turning to connecting lever (2), rotary ectosome to hole double fluid liquid switch (10) will rotate synchronously with steering wheel (5), so chaufeur only needs a little firmly operator is being depended on (1) to turn to connecting lever (2), steering wheel (5) will and then rotate, and operator will be with stopping to the position relative with the A point being parked in what angle B point, steering wheel also can forward stand after what angle to.Since rotary when rotating handgrip be so that the turning rate of the vehicle of opening gradually or closing gradually is more steady to the oilhole in the switch of hole.The direction contrary principles is identical during right-hand corner, according to chaufeur rotate the speed difference of handgrip, angular dimension that the relative B of A point is ordered also different, thus controlling the flow of hydraulic oil, also just controlling the turning velocity of steering wheel, owing to have the assistance of the control of energy saver and high pressure oil storage bottle, automobile speed less to the turning velocity influence of steering wheel, but in starting and in travelling chaufeur only by operator residing position with regard to perception steering wheel present located steering angle.So native system safety and stability, driver behavior technical risk are low.
