The beneficial effects of the utility model：Practicality, production cost is low, and structure is novel, and car accelerates more steady, no pause and transition in rhythm or melody
Sense, acceleration strength is big, and climbing capacity is strong.
Brief description of the drawings
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of high speed electric power train in vehicle application device of new structure, including shock-absorbing support frame 1 and motor 2, described damping
The one end of support frame 1 is provided with motor 2, the other end is provided with drive disk 4 by power input shaft 3, the motor shaft outer end on motor 2
Driving wheel is installed, the driven pulley outer cover on driving wheel and drive disk 4 is provided with driving belt 5, close to dynamic on shock-absorbing support frame 1
One end of power input shaft 3 is provided with power output shaft 6, and the trailing wheel of electric car is arranged on the power output shaft 6, power input shaft
Gear-box 7 is installed between 3 and power output shaft 6, passes through the biography in gear-box 7 between power input shaft 3 and power output shaft 6
Moving gear group is connected.
Motor shaft outer end on described motor 2 is provided with radiator fan 8, and radiator fan 8 is located at the outside of driving wheel.
When motor 2 starts primary low speed rotation, the rotating ratio of described driving wheel and driven pulley is 3: 1, and motor 2 revolves at a high speed
When turning, the rotating ratio of driving wheel and driven pulley is 1: 1.48.
After the described speed change of gear-box 7, the rotating ratio that one end of power input shaft 3 is provided with power output shaft 6 is 4:
1。
The outside of described driving belt 5 is provided with a protection casing, and case lid, shock-absorbing support frame 1 are provided with casing
On the mud guard of the trailing wheel for blocking electric car is installed.
Electric car of the present utility model is installed, its transmission is：Motor shaft on motor 2 drives driving wheel rotation, driving wheel
Driven pulley is driven to rotate by driving belt 5, driven pulley drives power input shaft 3 to rotate, and power input shaft 3 passes through travelling gear
The trailing wheel rotation of electric car on group drive power output shaft 6, realizes rear wheel drive.
The utility model can reach 80 yards of rotating speeds, and national requirements motorcycle mountain area of climbing, all may be used no more than 85 yards
So that common electric car 1: 1 accelerates easily hair punching, climbs weak.
The utility model is：When motor 2 starts primary low speed rotation, the rotating ratio of described driving wheel and driven pulley is 3:
1 (also just says：Actively rotate 3 circles, the driven circle of rotation 1), when motor 2 rotates at a high speed, the rotating ratio of driving wheel and driven pulley is 1:
1.48 (that is actively rotating 1 circle, the driven circle of rotation 1.48).After the described speed change of gear-box 7, power input shaft 3
(that is one end is provided with the rotating ratio of power output shaft 6 as 4: 1：The circle of the rotation of power input shaft 34, power output shaft 6 revolve
Turn 1 circle).
So start to walk more steady, acceleration strength is big, equivalent motor, and in the case of Same Efficieney, car can accelerate to 80
Kilometer/hour.
