Abstract
The utility model discloses a novel speed-raising transmission mechanism of an electric vehicle, which belongs to the transmission device of an electric bicycle or an electric motorbike. The novel speed-raising transmission mechanism is characterized in that an electric motor is mounted at the middle part of the rear wheel close to the lower end of the vehicle frame of the electric vehicle, the electric motor rotates a gear of a central shaft and drives a speed-raising gear to raise speed and then rotates an overrunning clutch to work, a belt pulley drives a gear-tooth-shaped rear tensioning belt pulley to work to form the effect of infinitely variable speed, the rear tensioning belt pulley rotates a central speed changing gear and the speed changing gear rotates a glide gear of a rear wheel shaft and the glide gear rotates the rear wheel shaft to work. The utility model utilizes the overrunning clutch in the belt transmission of the motorbike; meanwhile, the utility model is combined with the speed changing mechanism of the prior known electric vehicle or motorbike to form an infinite variable speed. Therefore, the utility model designs an ideal electric vehicle with an independent electric motor, which has the advantages of stable starting, rapid raising speed, strong climbing ability, long gliding time and low electricity consumption.
Description
Technical field
The utility model relates to the driving device of Electrical Bicycle or battery-operated motor cycle, a kind of specifically later-model battery-driven car acceleration transmission mechanism.
Background technology
The development battery-driven car is current industrial a kind of social demand.Battery-driven car is because multiple factors such as environmental protection, safety are very popular.And the structure of existing battery-driven car mainly all is that motor is directly installed on the main shaft of trailing wheel, realizes its operation.Though this structure is simple, it is difficult to have a starting, and power consumption is big, and hill climbing ability is poor, have in addition the implementation of must getting off when going up a slope, and the speed of a motor vehicle waits many shortcomings too slowly.Another battery-driven car is the battery-driven car that is provided with gear case and back axle, and this structure utilizes the output of motor to pass to special-purpose back axle again after gear case slows down, and to drive the trailing wheel of battery-driven car, this structure is reliable, but has complex structure, heaviness, cost height.
Show that from the pertinent data retrieval that comprises Chinese patent the patent of the invention or utility model of existing tens relevant drive mechanism of electric motor car at present is as the patent No.: 01237753.8; 01261930.2; 00263638.7; 99243378.9 and 02236393.9 etc.But see as yet motor is not installed in central frame beam bottom, the mechanism that combines with centrifugal clutch and change speed gear box again by the belt drive system on the driven by motor overriding clutch.For this reason, the inventor has applied for " a kind of later-model drive mechanism of electric motor car ", the patent No.: 200720007028.3 and application number: 200710008961.7 patent, put into practice through production practice over one year, the mechanism that discovery has centrifugal clutch can waste, and motor requires per minute to reach 6000 to change, so there are bad problems such as motor can generate heat, require further improvement.
The utility model content
In order to overcome the deficiency of prior art, the purpose of this utility model is will provide a kind of motor is installed in bottom of frame, the mechanism that is combined with change speed gear box again by the belt drive system on the driven by motor overriding clutch.This mechanism can realize the driving starting steadily, the power consumptive province, and moving velocity is fast, and hill climbing ability is strong, and the athermic a kind of later-model battery-driven car acceleration transmission mechanism of motor.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of later-model battery-driven car acceleration transmission mechanism, it is characterized in that: electrical motor is located to be equipped with by the centre (lower end of stretcher) of trailing wheel in the vehicle frame lower end at battery-driven car, be installed with the center shaft gear on the main shaft of electrical motor, center shaft gear and speed-raising gear mesh, also be fixed with overriding clutch and belt pulley on the axle of speed-raising gear, be connected with belt on the belt pulley, the other end of belt is connected with another back belt pulley, the main shaft of back belt pulley is mounted on the main shaft that the change speed gear box of battery-driven car stretches out, this root main shaft is connected with spring and spring capping at an end of back belt pulley, the partial fixing that back belt pulley stretches in the change speed gear box has final drive gear, final drive gear and back axis variable gear engagement, the wheel shaft other end of back axis variable gear is fixed with the axis variable gear, axis variable gear and the engagement of trailing wheel sliding gear, the wheel shaft of trailing wheel sliding gear is the battery-driven car hind axle.
Described overriding clutch is provided with 3～12 balls in the middle of it.
Need only starter motor during work, drive the speed-raising gear behind the electrical motor center of turn shaft gear and play the speed-raising effect, rotate overriding clutch work (overriding clutch its in 6 balls are arranged) then, axis spring ball bonnet and belt pulley are formed, stretch pulley carries out work and has formed the stepless change effect after the belt pulley drive profile of tooth, rotates the hind axle sliding gear with variable gear behind the back stretch pulley center of turn variable gear and carries out work by sliding gear commentaries on classics hind axle.
The beneficial effects of the utility model are: because the utility model has been implemented change with the installation site of motor dexterously, and utilized the overriding clutch in the belt-driving of motor bike, and removed and used centrifugal clutch mechanism in the original design, the utility model combines with existing known battery-driven car or motor bike speed-changing mechanism more simultaneously, has formed electrodeless variable-speed.So the utility model design is a kind of independent electric motors (per minute only needs 3500 commentaries on classics) that has, and starts to walk steadily, speed-raising is fast, and hill climbing ability is strong, and coasting time is long, the desired electrical motor-car of power consumptive province.Therefore, the utility model can reach the purpose of drafting.
