The motor is fixedly connected with the speed reduction gearbox, the clutch comprises a driving part and a driven part, a wedge is disposed between the driving part and the driven part, a sun gear is arranged at the end of the motor output shaft, the sun gear, the planet gears and the planet carriers form a planet gear speed reducer,an annular gear is arranged on the inner wall of the speed reduction gearbox and meshed with the planet gears, the planet carriers are fixedly connected to the driving part of the clutch, the driven part of the clutch is fixedly connected to the rear cover of the gearbox, and the rear cover of the gearbox and the clutch are respectively mounted on a fixed shaft via bearings. The rear-mounted speed reducer has the advantages that the output torque of the total reducer motor is large, the total reducer motor is compact in structure, and oil in the speed reduction gearbox can not seep into the motor, so that the motor can work more safely, service life of the motor is prolonged, manufacturing cost of the motor is reduced, and integral performance of the motor is improved.
Description
Technical field
The utility model is applicable to field of mechanical technique, relates to a kind of rear-mounted speed reduction gearing of hybrid power motorcycle.
Background technology
Speed reduction gearing is a kind of power drive, mainly is to utilize the multi-stage gear transmission to carry out rate conversion, thereby the output shaft revolution of motor shaft is converted to needed revolution, and obtain the device of bigger torque.At present, the speed reduction gearing of selling on the market, mainly being linked to each other with motor by reducing gearbox forms.This connection mode is exactly that front end cover with motor is fixed on the rear side housing of reduction gear casing.During work, the motor output shaft outputting power by the multi-stage gear transmission, is realized the purpose of slowing down.
Present battery-driven car has adopted motor high speed acceleration and deceleration mechanism to drive substantially, and some is that rotor with high speed revolution carries out reduction of speed by planetary reduction gear, thereby drives the electric vehicle hub rotation again; Some adopts rotor to drive the sun wheel rotation, and then the drive planetary wheel slows down.When adopting planetary wheel to slow down, mostly be that a gear is installed on the motor output shaft, restricted the deceleration effect.In addition, existing speed reduction gearing all will add lubricating oil usually and be lubricated, and the leakage problem of lubricating oil is a big problem of the sector, after oil is leaked to motor internal, can have influence on the working stability of motor always in order to realize arriving at a high speed low-tach transition.
The utility model content
It is big that the technical matters that the utility model solves provides a kind of output torque, the rear-mounted speed reduction gearing of the hybrid power motorcycle of compact conformation, motor long service life.
A kind of rear-mounted speed reduction gearing of hybrid power motorcycle, described rear-mounted speed reduction gearing comprises motor, deceleration box, be installed in motor output shaft, planetary wheel, pinion carrier, power-transfer clutch in the deceleration box, and casing bonnet, motor is captiveed joint with deceleration box, and described power-transfer clutch comprises driving link and driven member, is provided with voussoir between driving link and the driven member; Described motor output shaft end is provided with gear, described gear constitutes epicyclic reduction gear as sun wheel and planetary wheel, pinion carrier, the deceleration box inwall is provided with internally toothed annulus, internally toothed annulus and planetary wheel engagement, pinion carrier captive joint power-transfer clutch driving link, power-transfer clutch driven member captive joint casing bonnet; Described casing bonnet and power-transfer clutch respectively by bearing installation on anchor shaft.
Preferably, be provided with seal ring between described deceleration box inwall and the motor output shaft.
Preferably, described motor is connected by screw with deceleration box.
The beneficial effects of the utility model are: because profile of tooth is made in the motor output shaft end, increased the transmitting ratio of whole reducing mechanism, therefore, the output torque of whole reducing motor is big, compact conformation.In addition, in above-mentioned rear-mounted speed reduction gearing, be provided with seal ring between the inwall of motor output shaft and deceleration box, after being provided with seal ring, can prevent that oil in the deceleration box from penetrating in the motor goes, and the work that motor can be safer has like this increased service life of motor.In addition, the low cost of manufacture of this motor, the overall performance of motor improves.
Description of drawings
Fig. 1 is a sectional structure scheme drawing of the present utility model.
Among the figure, motor 1, motor output shaft 1a, anchor shaft 1b, deceleration box 2, casing bonnet 2a, planetary wheel 3, internally toothed annulus 4, seal ring 5, power-transfer clutch 6, power-transfer clutch driving link 6a, power-transfer clutch driven member 6b, voussoir 6c, bearing 7.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, a kind of rear-mounted speed reduction gearing of hybrid power motorcycle comprises motor 1, motor output shaft 1a, anchor shaft 1b, deceleration box 2, casing bonnet 2a, satellite gear 3, internally toothed annulus 4, seal ring 5, power-transfer clutch driving link 6a, power-transfer clutch driven member 6b; Motor 1 and deceleration box 2 link together by screw, internally toothed annulus 4 is fixed together with deceleration box 2, motor output shaft 1a is meshed with three satellite gears 3, three satellite gears 3 are meshed with internally toothed annulus 4, and power-transfer clutch driving link 6a and power-transfer clutch driven member 6b are fixed together with satellite gear 3 and casing bonnet 2a respectively.Gear box cover 2a and power-transfer clutch 6 all are fixed on the 1b by bearing 7.
The principle of work of this rear-mounted speed reduction gearing is as follows:
At first, this rear-mounted deceleration box is installed on the trailing wheel of motor bike by the outshot of casing bonnet 2a; During work, motor 1 energising, motor output shaft 1a rotates, and drives three satellite gears 3 that are meshed with it and rotates; After satellite gear 3 rotates, if this moment free-wheel clutch driven member 6b relative to driving link 6a be that clockwise direction rotates, voussoir 6c will be stuck between driving link 6a and the driven member 6b, and then driven member 6b is in the same place with driving link 6a is locked, this moment, whole power-transfer clutch was in linkage status, at this moment satellite gear 3 will drive power-transfer clutch driving link 6a and power-transfer clutch driven member 6b rotation, and then drives casing bonnet 2a rotation, finally drives the rotation of motor cycle rear wheel.
In the motor bike reversing, driven member 6b is with respect to driving link 6a anticlockwise motion, and voussoir 6c is pushed run-off the straight, certain space can appear between driven member 6b and driving link 6a, at this moment, power-transfer clutch is in released state, and the rotation of driving link 6a can not passed on the driven member 6b.
