The specific work process of the present invention is as follows：
For convenience of description, this speed changer is so that with exemplified by automobile, and when vehicle stops, gear joystick and knob are in
Park position or neutral position, the swash plate in speed changer, under the control action of control system, disk is perpendicular to the axis of input shaft
Line and parallel to the end face of cylinder body, variable-speed clutch is in discrete state in speed changer（Referring to Fig. 1）.When vehicle traveling needs to become
When the output shaft output power of fast device and operating, gear joystick or knob are placed in drive shift, control system can receive
Start the instruction of variable-speed clutch, while driving motor power supply of the control system into variable-speed clutch, it is made to operate and pass through
Worm screw, worm gear, the operating of screw rod inner sleeve are driven, so as to drive screw jacket, thrust bearing, swash plate adjustment component simultaneously to cylinder body
Orientation moves, and the back face of one end and swash plate one end of swash plate adjustment component is caused to touch, and makes swash plate under its driving
It deflects and tilts, the disk of inclined swash plate forms the inclined-plane of the axis direction compared with input shaft, and at this moment swash plate is in input shaft
Be rotated by, and the outer sleeve of spiral plunger is driven to be slided to the right side direction of cylinder body, the outer sleeve in spiral plunger
By spiral lamination inner sleeve is driven to rotate, inner sleeve is made to generate rotation together with freewheel clutch and planetary gear, while in driving
Heart gear and output shaft generate rotation, at this moment, since central gear is reversed to spiral plunger and cylinder body application by planetary gear
Power, having makes the counter-rotational trend of cylinder body, and the freewheel clutch between cylinder body and casing has the work that cylinder body is prevented to invert
With output shaft drives vehicle to travel by main reducing gear at this time（Referring to Fig. 2）.Control system can root in vehicle travel process simultaneously
The angle of inclination of swash plate in speed changer is adjusted according to the height of the rotating speed of input shaft, the rotating speed of output shaft, rotating speed gets over high dip
Angle is bigger, and the rotating speed of output shaft is also higher, and driving vehicle gives it the gun, and when speed is increased to certain speed, swash plate is controlling
Under the control action of system, angle of inclination reaches maximum, so that swash plate drives the stroke that spiral plunger slides close to borded pile
Stroke during the outer sleeve driving inner sleeve rotation of plug, swash plate generates the driving force rotated by spiral plunger to cylinder body, when this
A driving force be more than cylinder body freewheel clutch is applied opposition when, until make input shaft, swash plate, spiral plunger, cylinder body,
The components such as planetary gear, central gear, the outer shroud of freewheel clutch and output shaft are gradually mutually locked, promote input shaft, swash plate,
The components such as spiral plunger, cylinder body, swash plate and output shaft gradually carry out entirety in the same direction, and with the operating of angular speed, power passes through speed change
Device driving vehicle travels at a relatively high speed, and speed changer completes the process from starting to acceleration at this time.When being met in vehicle travel process
Be deteriorated to road conditions, load aggravates and situations such as braking to when making vehicle deceleration, control system will be according to input shaft, output shaft
Rotating speed adjusts the angle of inclination of swash plate in speed changer, and each component will unlock in transmission assembly, that is, exit overall operation state,
The load of vehicle more loaded vehicle speed is lower, and the angle of inclination of swash plate is also smaller, various to adapt to adjust transmission when output torque
Operating mode, at this point, speed changer complete from vehicle start to accelerate and according to road conditions, load variation and situations such as braking deceleration come
Adjust the entire speed-change process for being driven when torque.This buncher has higher transmission efficiency, gearratio adjustable range
Greatly, while maximum output torque, moreover it is possible to maximum speed is exported, so as to reliably complete automatic stepless speed change function.
To the above description of disclosed embodiment, those skilled in the art is enable to realize or use the present invention.To these
The many places modification of embodiment is apparent to those skilled in the art, and the general principles defined herein can be
On the premise of the spirit or scope for not departing from invention, realize in other embodiments.Therefore, the present invention will be not restricted to this paper institutes
These embodiments of display, and it is to fit to the widest range consistent with principles disclosed herein and features of novelty.
