Description
Technical field
It the utility model is related to a kind of speed change gear, and in particular to a kind of automobile-used Double speed variable speed mechanism.
Background technology
The power of original battery-operated motor cycle, by DC motor Driver, (reach several because the output speed of direct current generator is higher
Between thousand revs/min to 10,000 revs/min), this rotating speed can not be fed directly on the wheel hub of battery-operated motor cycle to transmit
Power, therefore, the dynamic design of originally battery-operated motor cycle is such：The rotating speed of direct current generator is inputed into a reductor
Structure, the rotating speed of direct current generator is reduced to the requirement of design by speed decreasing mechanism while lifts moment of torsion, then this rotating speed is passed to
Wheel hub, produce the power for making vehicle advance.
This reduces then fixation reducing gear that the rotating speed of direct current generator inputs to wheel hub by speed decreasing mechanism, and it is lacked
Fall into as single reduction of speed data can only be realized.And during the actual use of battery-operated motor cycle, a variety of roads can be encountered
Condition, environment, such as upward slope, level road, descending, heavy load, middle load, underload etc..When battery-operated motor cycle is travelled in uphill way
Or in the case of heavy load, its rotating speed is too high and moment of torsion is insufficient, may result in DC overload ablation；And when vehicle traveling is flat
Under ways section or light load conditions, the rotating speed that can find it again is too low and moment of torsion is excessive causes not reaching desired speed；Further,
This fixed speed decreasing mechanism can not well adapt to rotating speed and torque demand of the vehicle when being fully loaded with and being unloaded.Finally, this
Kind of mechanism, it have impact on endurance of the grade climbing performance of battery-operated motor cycle, load-carrying ability, acceleration and battery etc..
In view of the above-mentioned problems, patent CN203703038U (Patent No. ZL201420069713.9) discloses one kind《Electricity
Electrical automobile double-velocity transmission》Although the conversion of its two kinds of speed that can realize electric automobile, its complicated integral structure,
Clutch needs to set clutch and the first master gear and the second master gear positioned at two stations, required gear quantity compared with
It is more, cost is not only increased, also increases installing space, needs further to improve.
