Abstract
The utility model relates to a energy-saving and automatically speeding up transmission device of a motorcycle, which comprises a stepped change gear system, a non-stepped shift driving pulley and a driven pulley, wherein, the driving pulley is arranged on an output shaft of the stepped change gear system, the driven pulley is arranged on a rear wheel shaft, and the driving pulley and the driven pulley are connected by a transmission belt. The utility model combines the advantages of a stepped change transmission device and a non-stepped change transmission device of the motorcycle, thus being capable of effectively using the power of an engine to greatly improve the dynamic performance, reduce oil consumption, vibration, noise and pollution and prolong the service life of the engine, meanwhile, the utility model has the advantage of non-stepped gear shift, resulting in that the speed of the motorcycle can be promoted by 20 percent -40 percent with the same power generated by the engine.
Description
Technical field
The utility model belongs to a kind of vehicle transmission gear, particularly relates to a kind of motor bike driving device.
Background technology
Motor bike has two kinds of speed change type of drive, i.e. step change transmission and stepless variable drive.No matter the step change type of drive is tractive performance and economic performance, or service life, all is better than the motor bike of stepless variable drive, and the shelves number is many more, and performance is good more.Because the shelves number is many more, can make work under near the rotating speed of the driving engine maximum power scope of being everlasting, and the engine speed change scope is little, the average power height, improved the tractive performance of motor bike like this, promptly improved the acceleration capacity and the hill climbing ability of motor bike, the shelves number is many, has also increased the possibility of driving engine low oil consumption district work, thereby improved the economy of motor bike, can make the speed changer structure complexity but the shelves number is many, quality increases, and cost improves.Because the most employing of step change type of drive chain gear, its weak point is that chain is loose easily, and noise is big, need often to adjust and apply lubrication oil, and limited shelves number can not be brought into play engine power performance, economic performance more fully.The advantage of stepless variable drive is easy and simple to handle, can change transmitting ratio within the specific limits arbitrarily, but as preceding described, its tractive performance and economic performance is relatively poor than the step change transmission.
The utility model content
The utility model is in conjunction with step change and infinite variable speed advantage, provides a kind of not only tractive performance good but also can improve the auto acceleration driving device of the speed of a motor vehicle.
For achieving the above object, the utility model adopts following technical scheme: the energy-conservation auto acceleration driving device of a kind of motor bike, it is characterized in that, it includes a grade change gear train, stepless change driving pulley and driven pulley, driving pulley is contained on the output shaft of step change train of gears, driven pulley is contained on the hind axle, and driving pulley is connected by drive belt with driven pulley.
Driving pulley is made up of interior half one and outer half one, centrifugal roller is housed between interior half one and swash plate and is contained on the output shaft by sleeve, and outer half one is fixed tightly on the output shaft.
Driven pulley is formed on hind axle and by interior half one and outer half one by sleeve set, interior half one is fixed tightly on the sleeve, outer half one is enclosed within on the sleeve and can slides on sleeve, between outer half one and sleeve ends torsion spring is housed, interior half inner end is equipped with ratchet and pawl arrangement, and ratchet and pawl arrangement is fixed with engagement pawl outward.
On the step change train of gears output shaft sprocket wheel is housed, together footpath sprocket wheel also is housed on the axle of driving pulley, two sprocket wheels connect by chain.
The utility model had both adopted the change gear train of step change driving device such as chain gear, make it have the advantage of step change driving device, can effectively utilize the power of driving engine, significantly improve its tractive performance, reduce oil consumption, vibration, noise and exhaust emission, prolonged the service life of driving engine, adopted simultaneously the belt sheave structure of positive infinite variable driving device again, make it possess infinite variable speed advantage, make the speed of a motor vehicle of motor bike under same engine power, can improve 20%～40%.
Description of drawings:

Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Embodiment 1: this motor bike driving device includes grade change gear train 1, stepless change driving pulley and driven pulley.Step change train of gears 1 can adopt the change gear train in the motor bike step change driving device, and it belongs to known technology, no longer detailed icon and narration.Driving pulley is contained on the output shaft 4 of change gear train 1, and driven pulley is contained on the hind axle 5, and driving pulley is connected by drive belt 6 with driven pulley.Driving pulley and driven pulley can adopt driving pulley and the driven pulley in the belt pulley positive infinite variable driving device.Driving pulley is made up of interior half one 2 and outer half one 2 ', and interior half one 2 and 7 of swash plates are equipped with centrifugal roller 8 and are contained on the output shaft 4 by sleeve 9, and outer half one 2 ' is fixed tightly on the output shaft 4.Driven pulley is sleeved on the hind axle 5 by sleeve 10, and interior half one 3 of driven pulley is fixed tightly on the sleeve 10, and outer half one 3 ' is enclosed within on the sleeve 10 and can slides on sleeve, between outer half one 3 ' and sleeve 10 ends torsion spring 11 is housed.Interior half 3 inner ends are equipped with known ratchet and pawl arrangement 12, and this ratchet and pawl arrangement 12 can make motor bike trailing wheel and driving device release the drive when deceleration is slided, thereby plays energy-saving effect.Be fixed with engagement pawl 13 outside the ratchet and pawl arrangement 12, play the effect that driven pulley 3 is combined with trailing wheel.
When the output shaft of motor bike step change train of gears 1 reaches setting speed, interior half one 2 of driving pulley moves outside vertically under the promotion of centrifugal roller 8, the resistance that outer half one 3 ' of while driven pulley also overcomes torsion spring 12 outwards moves, the effective diameter of belt 6 on driving pulley increased, effective diameter on driven pulley reduces, transmitting ratio is increased, thereby the speed of a motor vehicle of motor bike is improved.When output shaft 4 rotating speeds were lower than setting value, driving pulley and driven pulley all automatically reset, and motor bike recovers normal condition and travels.
Embodiment 2: as different from Example 1, present embodiment is equipped with sprocket wheel 14 on the output shaft 4 of step change train of gears 1, and also being equipped with together on the axle of driving pulley, footpath sprocket wheel 15, two sprocket wheels connect by chain 16.
