The purpose of this utility model is achieved in that
A kind of electric cycle of easy carrying of back-wheel drive comprises front-wheel, trailing wheel, and vehicle frame, storage battery, drive system, wherein said front-wheel is connected with the front portion of vehicle frame by the front-wheel axletree; Described trailing wheel is connected with the rear portion of vehicle frame by axletree; Described storage battery is fixed on the vehicle frame, is used for providing electric energy to drive system; Front portion at vehicle frame also is provided with the seat support tube, is used to install the seat of electric cycle, it is characterized in that:
Described drive system is arranged at the rear portion of described electric cycle, is connected with described trailing wheel, is used to drive trailing wheel and rotates.
The electric cycle of the easy carrying of described a kind of back-wheel drive is characterized in that: described drive system comprises
One differential gear is arranged in the tooth case, is used for the propulsive effort of drive system is delivered to the trailing wheel of electric cycle;
One motor is used to drive described differential gear and rotates the output shaft of described motor and the same axle mounting of described differential gear;
One long pass moving axis, the one end is connected with described differential gear, and the other end is connected with a wheel of described trailing wheel, is used for the power transmission of described differential gear is arrived trailing wheel;
One short pass moving axis, the one end is connected with described differential gear, and another of the other end and described trailing wheel taken turns and is connected, and is used for power transmission with described differential gear to trailing wheel;
One sleeve pipe is sheathed on the outside of described long and short transmission shaft.
The electric cycle of the easy carrying of described a kind of back-wheel drive is characterized in that: described drive system also comprises a motor fixed mount, is arranged at the outside of described sleeve pipe, is used for described drive system is connected to ground.
The electric cycle of the easy carrying of described back-wheel drive is characterized in that: described motor with by on screw retention and the described tooth case.
The electric cycle of the easy carrying of described a kind of back-wheel drive is characterized in that: described vehicle frame is provided with two sections support bodys.
The electric cycle of the easy carrying of described a kind of back-wheel drive is characterized in that: described motor fixed mount and vehicle frame are provided with the screw thread of coupling, are used to make the two connection.
The electric cycle of the easy carrying of described a kind of back-wheel drive is characterized in that: described vehicle frame is provided with a screw pin, the connection of two sections support bodys before and after being used for.
The utility model makes that its propelling thrust is powerful owing to adopted back-wheel drive, when loading big or up-hill journey, bigger applicable area is arranged; Secondly, turn to control easily, even the generation of possible some accidents is avoided in also operation easily of handicapped person or the elderly; Once more, can regulate two rotating speeds that trailing wheel is different, also can turn to easily or reverse end for end in narrow place.And,, when needs carrying electric cycle, can decompose easily and be carried because vehicle frame is a segmental structure.
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing,, can clearerly find out advantage of the present utility model by description to preferred embodiment.
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a trailing wheel facade cross-sectional schematic of the present utility model;
Fig. 3 is a trailing wheel cross-sectional plane schematic top plan view of the present utility model;
Fig. 4 is the connection diagram of the utility model drive system.
As Fig. 1, motor 18 and the same axle mounting of differential gear, differential gear is arranged in the tooth case 12, and motor 18 is connected with tooth case 12 by screw 20; One end of long pass moving axis 14 and short pass moving axis 16 is connected with differential gear in the tooth case 12 respectively, the other end is connected with two trailing wheels 28 respectively, the power of output is delivered to two trailing wheels 28 respectively and drives trailing wheel 28 rotations during with motor 18 work, sleeve pipe 24 is placed in the outside of long pass moving axis 14 and short pass moving axis 16, is arranged at sleeve pipe 24 outer motor fixed mounts 32 whole drive system is fixed in the back vehicle frame.
Still as Fig. 1, two sections support bodys connected combination and constitute before and after vehicle frame had, front vehicle frame 36 with after be connected with a screw pin between the vehicle frame, as long as this screw pin of outwarding winding promptly can be decomposed into vehicle frame front and back two parts.Wherein, a seat support tube 34 is installed in front vehicle frame 36 tops, is used to install the seat of electric cycle.
And for example Fig. 2 and Fig. 3 can clearerly find out the position relation between motor 18, differential gear, long pass moving axis 14, short pass moving axis 16, motor fixed mount 32 and the trailing wheel 28.
Fig. 4 for another example, differential gear is arranged in the tooth case 12, and its gear wheel shaft 26 stretches out outside the tooth case 12.At the axial end of motor 18, the output shaft and the differential gear of motor 18 are engaged, and its output shaft can drive differential gear and rotates when motor 18 rotates.The power lead of motor 18 is located in and guides storage battery in the conduit into, provides working power by storage battery to motor 18.At the axial other end of motor 18, a power-transfer clutch 22 coaxial with motor 18 output shafts is set.The rotation of motor 18 output shafts drives long pass moving axis 14 by differential gear and short pass moving axis 16 rotates, and further drives trailing wheel 28 rotations.Comprise a straight gear, a helical wheel and several bevel gear in the tooth case, the power of motor 18 drives long pass moving axis 14 and short pass moving axis 16 respectively by the interlock transmission of different gears in the tooth case 12, outputs power on the rear wheel 28.Simultaneously,, and make the velocity of rotation difference of two trailing wheels 28, when needs turn to or reverse end for end, turn to by the different velocities of rotation of two trailing wheels 28 with regard to being easy to by the rotation of differential gear in the tooth case 12.
It is pointed out that on the basis that does not break away from the utility model essence those of ordinary skill in the art can make various suitable distortion or replacement, still, all these distortion or replacement all should belong to protection domain of the present utility model.
