Abstract

The utility model belongs to the bicycles and particularly relates to a transmission mechanism for a bicycle free of a chain. A transmission mechanism axle penetrates a free hub to be connected through a free hub bearing. A movable fly wheel is connected with the outer end of the free hub, one end of a connection clamping disc is fixed to the axle, the other end of the connection clamping disc is connected with the movable fly wheel, the axle is connected with a rear fork through a bearing, and a crank is connected with the axle. By means of the transmission mechanism for the bicycle free of the chain, a sliding function and a fixed cog function of an axle-driven bicycle free of the chain and the sliding function of chain-free axle driving are achieved, and fast and simple switching between the sliding function and the fixed cog function is provided.

Description

Non-chain bicycle transmission mechanism
Technical field
The utility model belongs to bicycle class, relates to a kind of Non-chain bicycle transmission mechanism.
Background technology
In patent 1, propose can two-wheel turn to and before and after to the type of drive of the Chainless bicycle of riding, be, crank drives axletree, axletree drives flower-drum, flower-drum connects spoke and drives rim to rotate.This type of drive, wheel is advanced and is scrunched synchronous with people and direction is consistent, and people's pin is pedaled forward, and wheel is gone ahead; People's pin is static not to be pedaled, and wheel is static not to be walked; People's pin is kicked backward, and wheel is walked backward.This type of drive has its peculiar way on skill is ridden, but it cannot realize and sliding, if bicycle will be advanced forward, people must synchronously scrunch always.
Summary of the invention
The purpose of this utility model is to propose a kind of Non-chain bicycle transmission mechanism that can realize flywheel slip alive and the fricton-tight function of fixed sprocket.The technical scheme that the utility model adopts is that this device comprises crank, wheel shaft, connection button dish, the flywheel of living, flower-drum, bearing.It is characterized in that: wheel shaft, through flower-drum, connects by flower-drum bearing; The flywheel of living is twisted solid on flower-drum; Connect button dish and be arranged at flywheel outside, one end is fixed on wheel shaft, and the other end blocks flywheel alive, and the gear teeth are connected with it; Wheel shaft is combined by bearing with back vent; Crank is connected with wheel shaft.Flower-drum both sides are established to connect and are buckled dish and the flywheel body of living, and the connection button dish in left side is provided with clutch, control its with the interlock of left side flywheel teeth with separated.
The advantage the utlity model has and beneficial effect: the utility model has solved the realization that drives bicycle coasting function and dead chikung energy without chain wheel shaft.Utilize relative easy means to realize without the shaft drying wheel function of chain wheel, and provide the fast simple switching of wheel function with dead chikung energy, make to drive bicycle can have chain to live to realize and sliding bicycle with freewheel as common without chain wheel shaft, also can clutch switch realize have chain extremely fly bicycle the same without sliding the mode of riding.The function of riding, the purposes and recreational that without chain wheel shaft, drive bicycle have been increased.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present utility model;
Fig. 2 is that the utility model connects button dish front schematic view.
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Without chain drive, by crank 5, wheel shaft 3, connects button dish 2, the flywheel 1 of living, and flower-drum 8, bearing 4,9 forms; Crank 6 one end connect rides 7, and the other end is connected with wheel shaft 3; Back vent 5 is connected with wheel shaft 3 by bearing 4, and wheel shaft 3 is attached thereto by flower-drum bearing 9 through flower-drum 8; The flywheel 1 of living is arranged on flower-drum 8; Connect button and coil the fluted disc that 2 one end withhold flywheel 1 alive, the other end and wheel shaft 3 are fixing.Clutch 10 is when being used function, and during state, in separation, it is inoperative that left side connects button dish 2+ flywheel 1 combination alive.
In the working process of riding, the crank 6 forced belt axis of a movable block 3 rotate, and wheel shaft 3 drives and connects button dish 2, is transmitted to flywheel 1 alive, and the flywheel 1 of living drives flower-drum 8 that wheel is moved ahead.
When sliding, wheel drives flower-drum 8 to rotate, and owing to being provided with slide block in the flywheel 1 of living, slide block slides and makes to live the fluted disc of flywheel 1 in relative to static (not rotating with flower-drum 8), and connection button dish 2, axletree 3 are all relative static with crank 6.
While using dead chikung energy, stir and connect clutch 10 on button dish 2, the connection button dish in left side is connected with the flywheel of living.Now, left and right sides flywheel works simultaneously, and respectively on the contrary to living flywheel.Pedal forward, right side flywheel band motor car wheel forward, left side flywheel slides; Kick backward, after the flywheel band motor car wheel of left side, turn, right side flywheel slides.Realize and extremely fly to control function.

Claims (2)

1. a Non-chain bicycle transmission mechanism, mechanism arrangement comprises crank, wheel shaft connects button dish, the flywheel of living, flower-drum, bearing, is characterized in that: wheel shaft is through flower-drum, and the flywheel of living connects flower-drum; Connect button dish one end and wheel shaft and fix, the other end connects the flywheel of living; Wheel shaft is connected by bearing with back vent; Crank is connected with wheel shaft.
2. a kind of Non-chain bicycle transmission mechanism according to claim 1, is characterized in that, described flower-drum both sides arrange to connect buckles dish and the flywheel body of living, and the connection button dish in left side is provided with clutch, controls itself and being connected with separated of left side flywheel.
