Embodiment 3: referring to Fig. 3, the driven gear 6 of differential mechanism meshes with gearbox output gear 5 and pump formula gear output gear 75 simultaneously.The power of pump formula gear is delivered to the driven gear of differential mechanism through pump formula gear output gear; The power of manual transmission is delivered to the driven gear of differential mechanism through the gearbox output gear.
Embodiment 4: referring to Fig. 4, driven gear 6 and the pump formula gear output gear 75 of 5 whiles of gearbox output gear with differential mechanism meshes.The power of pump formula gear is delivered to the driven gear of differential mechanism through pump formula gear output gear, gearbox output gear; The power of manual transmission is delivered to the driven gear of differential mechanism through the gearbox output gear.
The below illustrates its working procedure as an example of embodiment 1 example.Be in three gears when supposing normal vehicle operation, three, four keep off the ring gear 17 of putting into gear is in the state that meshes with three gear input shift gears, and flow control device 73 is in full open position.The power of motor is put into gear through clutch, gearbox input shaft 3, three, four gears at this moment, and ring gear 17, three keeps off input shift gears 13, three gears are exported shift gears 23 and are delivered to output shaft of gear-box 4, planetary pinion with the driven gear 6 of gearbox output gear 5, differential mechanism, differential casing, differential mechanism is delivered to semiaxis again, finally is with motor car wheel 18 to rotate.Pump formula gear input shaft 71 and the 72 free relative movement of pump formula gear output shaft, pump formula gear is transferring power not.when needs are changed to four gears, at first the flow by flow control device 73 control pumps reduces gradually, at this moment, the power of motor by the transmission of gearbox gradually transition be the transmission of pump formula gear, until flow control device is closed, the flow of pump is zero, engine power transmits through pump formula gear fully, be that the power of motor is through motor output gear 101, pump formula gear input gear 75, pump formula gear input shaft 71, pump formula gear output shaft 72, pump formula gear output gear 74, three gear input shift gears 13, three gear output shift gears 23 are transferred to output shaft of gear-box 4, again with gearbox output gear 5, the driven gear 6 of differential mechanism, differential casing, the planetary pinion of differential mechanism is delivered to semiaxis, drive vehicle wheel rotation.Then cut-off clutch, three, four gears that the move right ring gear 17 of putting into gear makes put into gear ring gear 17 and four gear input shift gears 14 engagements of three, four gears complete gearshift.After gearshift, again in conjunction with (certainly, also can in again in conjunction with clutch, perhaps again in conjunction with before clutch) after clutch, the flow of the pump by flow control device 73 control pump formula gears makes pump formula gear enter non-power delivery status to maximum.After the clutch combination, by the transmission of gearbox, namely present technique makes manual transmission when gearshift to the power of motor, has adopted pump formula gear as power transmission mechanism fully, power interruption when having avoided gearshift, travelling comfort and acceleration performance when improving gearshift.Simultaneously, because using the mode of hydraulic damping, pump formula gear controls transmitting torque, there is no friction means, the heat that produces during the moment of torsion of pump formula gear is controlled can conveniently dispel the heat in pump medium (being generally hydraulic oil), therefore can realize controlling under any moment of torsion, avoid the phenomenons such as clutch scaling loss of using friction clutch to cause, not only improved performance, simultaneously, greatly improve working life.
The innovation of present technique is on common manual transmission architecture basics, increases the pump adding type gear, and the input end of this pump formula gear directly is connected with the power of motor, and output terminal directly is connected with wheel power.Described pump formula gear can be controlledly with the transmission of power of motor to wheel, together with the driving gear of manual transmission, consist of and have gearbox two drive paths, that can realize not interrupting power gear shifting.
For pump formula gear, the input block that the flow by the flow control device control pump can control pump and the power between output block, transmission of power that can control pump formula gear.For example: when the flow of pump was maximum, input block and the power between output block of pump were very little, are in non-power delivery status; When the flow of pump was 0, the input block of the pump of pump and output block can not relatively rotate, and the moment of torsion that this moment, pump formula gear transmitted is maximum; The size of the flow of control pump can realize the control to pump formula gear transmitting torque size.Flow control device (control valve) can combine as a whole with pump, but also split (connecting by pipeline).
When vehicle was in non-gearshift state, the flow of the pump of pump formula gear was in maximum rating, and at this moment, power transition mechanism is transferring power not, and power passes to wheel through clutch and gearbox reduction gear.When needs were shifted gears, at first the pump duty of control pump formula gear reduced gradually, and at this moment, it is the transmission of pump formula gear that the power of motor transmits transition gradually by the reduction gear of gearbox, until power transmits through pump formula gear fully.This moment cut-off clutch and complete gearshift, then, in the time of in conjunction with clutch or afterwards or before, the flow of the pump of control pump formula gear makes pump formula gear enter non-power delivery status to maximum.Power interruption when gearshift has been avoided in the application of pump formula gear improves travelling comfort and acceleration performance.Certainly, pump formula gear also can be used as an independently gear use of gearbox.Present technique adopts pump formula gear transferring power during shifting gears, the power interruption when having avoided gearshift, and pump formula gear can carry out moment of torsion transmission control work under high pulling torque, make gearshift performance more outstanding, and have the long lifetime.
