Abstract
The utility model relates to a drive device of an electric vehicle, which combines motor drive and man power drive to mutually use one chain wheel to output power, an output chain wheel is fixed together with outer rings of two sets of linking ratchet mechanisms through screws, and inner rings of the two sets of the linking ratchet mechanisms are respectively connected with an output shaft and a middle shaft of a gearbox through screw threads; the two driving modes can separately work without interference and simultaneously overlap and work, so, the manufacture technology and assembly technology of the electric vehicle are simplified, the outer appearance is improved, the speed changing gear of the existing speed changing vehicle can be conveniently used, and the power performance of the electric vehicle is enhanced.
Description
The utility model proposes a kind of driving device for electric vehicle, be mainly used in battery-driven car, belong to machinery manufacturing technology field.
We know that small-sized electric car relies on motor-driven and two kinds of modes of manpower driving are travelled, these two kinds of propulsive efforts should be able to work alone and not disturb mutually, the mutual superposition of working simultaneously again selects appropriate driving device all influential greatly to dynamic property, economy and the outward appearance of battery-driven car.With the Electrical Bicycle is example, present motor drive mode can be divided into two classes substantially, one class is the built-in type of drive of rim, its motor and driving device all place in the middle of the rim, owing to be subjected to the restriction of locus, manufacturing process is complicated, and the power of motor, efficient and reliability also are affected; Another kind of is to adopt external mode, concrete type of drive has following several: frictional transmission, shaft drive, chain-driving and strap drive etc., these several type of drive are owing to adopted external motor and driver train, space bit has been equipped with bigger degree of freedom, but they all need use one to overlap independently transmission device, with man power driving mechanism and deposit, try with chain-driving side, then need two chains, one is the manpower chain drive-belt, another root is the motor-driven chain, has so not only increased technology difficulty and has influenced attractive in appearance.Motor-driven mechanism is difficult to increase mechanical variable speed device on the other hand, has influenced the tractive performance of vehicle.
The purpose of this utility model provides a kind of driving device for electric vehicle, keep external drive form, adopt a cover driver train, motor-driven and manpower driving are combined, a shared power take-off implement, can use the existing mechanical transmission system easily like this, the dynamic property of battery-driven car and outward appearance all are improved and improve.
Embodiment of the present utility model is: output chain gear is fixed together by the outer ring of screw and two cover interlock ratchet devices, and the inner ring of two cover interlock ratchet devices connects with the output shaft and the axis of change speed gear box by screw thread respectively.According to motion is that relative principle output chain gear also can be fixed together by the inner ring of screw thread and two cover interlock ratchet devices, and the outer ring of two cover interlock ratchet devices connects with the output shaft and the axis of change speed gear box by screw respectively.
The utility model compared with prior art has two big obviously advantages: the first has realized that motor-driven and manpower drive a shared power take-off implement, has simplified the manufacturing assembly technology of battery-driven car, has improved the outward appearance of battery-driven car; It two is the transmission systems that can use existing variable speed bicycle easily, has improved the dynamic property of battery-driven car.
Accompanying drawing is embodiment figure of the present utility model, and 1 is motor in the drawings, and 2 is change speed gear box, and 3 is ratchet device I, and 4 is ratchet device II, and 5 is output chain gear, and 6 is axis, and 7 are foot-operated crank.
Sets forth in detail technology implementation scheme of the present utility model in conjunction with the accompanying drawings, electrical motor is fixed on the change speed gear box, inner ring interlock by double-reduction gear and ratchet device I, the inner ring of ratchet device II is fixed on the axis, the outer ring of two cover ratchet devices is fixed together and forms the interlock ratchet device, and output chain gear also is fixed on the outer ring of interlock ratchet device.Should make the interlock ratchet device be in following operating mode during assembling: ratchet is in the forward strained condition when the ratchet inner ring is driving wheel, rotate thereupon the outer ring, when the ratchet outer ring is in reverse strained condition during for driving wheel, inner ring can not rotate thereupon, and ratchet device can adopt the existing parts of bicycle.When motor-driven, by the inner ring of gear reduction rear drive ratchet device I, at this moment ratchet device I is in the forward strained condition, rotate thereupon the outer ring, and drive output chain gear rotation horsepower output, and this moment, ratchet device II then was in reverse strained condition, and its inner ring can stressedly not rotate.When manpower drove, by the inner ring of foot-operated crank drive axis and ratchet device II, at this moment ratchet device II was in the forward strained condition, rotate thereupon the outer ring, and drive output chain gear rotation horsepower output, and this moment, ratchet device I then was in reverse strained condition, and its inner ring can stressedly not rotate.So no matter to be that motor-driven or manpower drive, can both to work alone and not disturb mutually that when these two kinds of propulsive efforts were worked simultaneously, two cover ratchet devices then were in the forward strained condition simultaneously, drive output chain gear work jointly.
According to motion is relative principle, said apparatus also can be made into: inner ring and the output chain gear of two cover ratchet devices are fixed together form the ratchet device that links, their outer ring connects together with motor driver and Manpower driver respectively, still can reach same purpose.
Because motor-driven and manpower drive a shared sprocket wheel horsepower output, this actuating device is placed in the axis position of battery-driven car, can use the transmission system that has variable speed bicycle now easily, make the dynamic property of battery-driven car that great raising be arranged.
