Its principle of work is such, when vehicle starting or acceleration, handle joystick (11), make its to arrow (d) to moving, and compression spring (12) spring perch (13) make control lever shaft (14) also to (d) to moving, and drive slip cap (17), compression spring (23) also to (d) to moving, at this moment cock connecting rod (31) to arrow (h) to rotation, because connecting rod is connected with cock (33), cock (33) also to (h) to turning an angle, because two ends each jagged (37) and (40) of through hole (35), so, through hole (35) is just sent into second controlling valve (47) to the highly pressurised liquid that Hydraulic Pump interface (34) is come through signal conveys pipe (41), after through hole (42) (45) (49), enter hydraulic actuating cylinder (58) through Throttle Opening Control interface (46), make piston (57) pressurized to (f) to moving, promoting throttle lever (60) strengthens throttle, simultaneously also enter hydraulic actuating cylinder (61) through stepless change signal conveys pipe (50), make piston (63) to arrow (S) to moving, promote intermediary wheel slide shaft (28) drive intermediary wheel (26) and to moving driven change wheel (25) speed is accelerated to (S), transmission shaft (24) speeds up.At this moment whole device has following several situation;
The motion of the motion of piston (63) and piston (57) just in time makes throttle strengthen with speed and promotes synchronously, the compression of spring (4) just in time is design-calculated best torque (is example to c to rotating with clutch output shaft (1)), declutch shift shaft (5) promptly not to (a) to moving also not to (b) to moving, at this moment, the highly pressurised liquid of coming from first controlling valve (32) makes throttle and speed strengthen the best that keeps engine output torque very soon.When the commentaries on classics degree of transmission shaft (24) centrifugal connecting rod (19) (20) when constantly accelerating also continues to increase, because centnifugal force, it is rotated with connecting rod rotation axis (21), slip cap (17) is moved to (1) direction, and drive cock connecting rod (31), cock (33) to (1) to rotation, at this moment through hole (35) diminishes with the port of signal conveys pipe (41), and breach (37) is opened gradually with pressure relief vent (38), the pressure that flows to second controlling valve is diminished, can be up to the pressure size for till keeping throttle and speed, transmission constant.When running into the increase of upward slope or surface resistance in this case as suddenly, the pressure of spring (4) can increase suddenly, shift fork (5) can be to (a) to moving, and connecting rod (8) is rotated with axle (9), drive slip cap (10) to (m) to moving, cock connecting rod (48) cock (44) to (m) to rotation, because rotation can make breach (52) open with the interface of stepless change signal conveys pipe (50) gradually.Make hydraulic actuating cylinder (61) release, speed, transmission reduces, and the through hole breach that leads to hydraulic actuating cylinder (58) can guarantee unimpeded, the signal of first controlling valve (38) conveying at this moment, because the reduction of speed, centrifugal connecting rod (19) (20) centnifugal force diminishes, slip cap (17) drive cock connecting rod (31) to (h) to commentaries on classics, the signal of signal conveys pipe (41) conveying at this moment becomes high-voltage signal again, and compression piston (57) strengthens throttle.When the throttle reduction of pushing the speed, the pressure that spring (4) is subjected to can diminish, declutch shift shaft (5) to (b) to moving, connecting rod (8) can drive slip cap (10) cock connecting rod (48) cock (44) to (n) to rotation, stepless change signal conveys pipe (50) is opened gradually, and hydraulic actuating cylinder (61) keeps equal pressure with (58).
If when normal walking, run into descending, the pressure of spring (4) can reduce, declutch shift shaft (5) to (b) to moving, cock (44) just to (n) to rotation, at this moment breach (55) pressure that can shed hydraulic actuating cylinder (58) reduces throttle, and through hole (49) can keep the unimpeded of hydraulic actuating cylinder (61) with breach (53), because throttle reduces, speed can be reacted at once, centrifugal connecting rod (19) (20) can make cock (33) make signal pressure become high pressure to (h) to rotation, piston (63) pressurized, stepless change speeds up.After throttle reduced the speed increasing, the pressure of spring (4) can continue to increase, and arrived spring pressure normal back cock (44) and was returned to position among the figure again.The principle of this structure is, is standard plus-minus throttle or speed of increasing and decrease under the situation that keeps the best output torque of driving engine to handle speed signal.
The driving device of above structure, not only can be used on the automobile, and can be used on other power actuated vehicle, as trac., motor bike etc., can also adopt the circuit control device (not marking among the figure) of above-mentioned principle, such as " speed control part " being used a variable resistance, " speed test section " becomes also can be with the power supply of velocity variations, " moment of torsion test section " also can adopt electric circuit inspection, and controlling valve can adopt electromagnetic control, but groundwork is same as described above.
In a word, utilize this device can be, the energy-conservation generation good effect of self-propelled vehicle to the operation of chaufeur.
