Description
Technical field
The utility model varying-speed machinery class, is specifically related to a kind of mountain bike electrodynamic type multi-stage transmission mechanism.
Background technology
At present, along with the development of society, traffic is also more and more blocked up, short distance distance, by bike can be convenient.But derailleur at present, speed change is convenient not; Particularly in the place that road climb and fall is serious, want to realize quick speed change very difficult.
Summary of the invention
In order to solve above-mentioned Problems existing, the utility model provides a kind of mountain bike electrodynamic type multi-stage transmission mechanism.
The utility model is achieved through the following technical solutions:
A kind of mountain bike electrodynamic type multi-stage transmission mechanism, comprises and flies core, described in fly core and be arranged on rear axle; Described fly core is provided with fly core groove; Described flying is provided with interior steel ball in core groove; The described core that flies is provided with near the side of miniature motor and flies core chuck; Described flying is provided with interior steel ball in core chuck internal diameter groove; Described flying is provided with outer steel ball in core chuck external diameter groove; Described fly core with fly, outside core chuck, inner ratch gear is installed; The described core arranged outside that flies flies shell; The described shell that flies is connected by steel ball with the described core that flies; Describedly fly core and described rear axle is connected as a single entity, and be nested on bicycle rack.
Described another circle groove flying core chuck outside diameter wall and be provided with, is arranged with steel ball in several in it; Several outer steel balls of arrangement in the described circle groove flying that core chuck inner diameter wall is arranged.
Core is provided with gear piece to described flying; Described six gear pieces coaxially connected, each described gear piece at least comprises a upper key way.
Described micro-machine is arranged on the right-hand member of the gear piece of largest diameter; Described miniature motor is connected with axle, and drives it to rotate.
The beneficial effects of the utility model: the utility model has the advantages such as compact conformation is easy to use.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
In figure: 1, miniature motor 2, gear piece; 3, shell is flown; 4, core is flown; 5, axle; 6, interior steel ball; 7, outer steel ball; 8, core chuck is flown; 9, interior quil wheel; 10, core groove is flown.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of mountain bike electrodynamic type multi-stage transmission mechanism described in the utility model, comprise miniature motor 1, gear piece 2, fly shell 3, fly core 4, axle 5, interior steel ball 6, outer steel ball 7, fly core chuck 8, interior quil wheel 9, fly core groove 10 and key way 11; The described core 4 that flies is located on axle 5, flies to be provided with interior steel ball 6 in core groove 10; Described flying is provided with interior steel ball 6, outer steel ball 7 in core chuck 7 inside and outside footpath groove 10; Be provided with in described overcoat inner ratch gear be enclosed within fly core with fly outside core chuck; Described fly shell 3 by steel ball 6 with fly core 4 and roll and coordinate, fly core 4 outer peripheral face and be provided with and fly core groove 10; The described core 4 that flies is flying core chuck 7 one end, flies core 4 and is connected as a single entity with axle 5 and is nested on bicycle rack; Describedly to fly in another circle groove 10 that core chuck 7 outside diameter wall is provided with arrangement steel ball 6 in several, several outer steel balls 7 of arrangement in the circle groove 10 that its inner diameter wall extends.
Described miniature motor 1 is connected with axle 5, and drives it to rotate.
When stepping foot-operated forward, chain-driving flywheel rotates forward, and at this moment flywheel internal tooth contains mutually with very heavy, and the rotatory force of flywheel passes to fuse by very heavy; Fuse drives rear axle and rear wheel, and bicycle realizes advancing.The sprocket wheel of multiple flywheel sheets on axis is combined, and the motor on axle can be with moving axis to rotate, and realizes auxiliary variable speed.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
