Abstract
The utility model provides a labor-saving crank reciprocating type transmission mechanism for bicycles. The utility model is characterized in that a left and a right cranks with fly wheels of both ends of the centre shaft of the bicycle can realize alternately upward and downward reciprocating drive controlled by a tractive loop formed by a reset cable arranged along the vertical pipe of the bicycle; a spacing ring is shielded in a specified range to regulate and control the size of crank throw or reset outer corner. The transmission mechanism has the advantages of simpleness, reliability, low cost and convenient assembly and production, is widely suitable for different drive of the bicycles, and is particularly suitable for a load bicycle or a pedicab which needs large force to drive.
Description
The utility model relates to a kind of transmission mechanism of bicycle, the reciprocating type transmission mechanism of bicycle of particularly a kind of labour-saving crank.
The effect of transmission mechanism of bicycle is that manpower is converted into the power of driving.What modern bicycle generally adopted is axis-crank-chain drum revolution, mechanism form by the chain drive rear wheel, this mechanism exists up and down two motion dead points when crossing (the legpower active line is vertical with the axis, drive torque is zero), makes us doing not feel like oneself and easily produces fatigue.
In order to address this problem, people proposed many no dead points transmission device scheme.As British patent 2246986, Chinese patent 94242346.1 or the like.Not enough is that this type of scheme mostly needs to set up the member of some inconvenience system dresses or make industrial standard car body remodeling, thereby influence is implemented and popularized.
The utility model provides a kind of crank reciprocating type transmission mechanism of bicycle, and it can eliminate motion " dead point " and the consequent power waste that existing mechanism exists effectively, has reached laborsaving purpose.
The purpose of this utility model is achieved in that can distinguish relative axis at the left and right crank bicycle middle shaft two ends, the band flywheel does directed revolution, the cable wire of arranging along standpipe that resets forms the tractive loop, be used for controlling the reciprocating type driving that left and right crank is made alternatively up and down, that is: power crank is in work done, and the tractive by the cable wire that resets makes another crank get back to initial position specific, that be convenient to have an effect.
The utility model does not change existing bicycle standard car body, does not increase the member such as lever yet, is characterized in reliable transmission, simple in structure, and parts are few, is convenient to make and repacking, and is with low cost.
Below in conjunction with accompanying drawing mechanism is further described.
Fig. 1 is a structural scheme of mechanism of the present utility model.
With reference to Fig. 1, conjuncted left crank-flywheel (1) and right crank-flywheel (6) are contained in the two ends of axis (3), have left and right the leading around lock-bit that connects cable wire (8) usefulness that resets and follow closely hole (2), (7) on these two flywheel cylindricals.Cable wire after the connection forms two loops before and after the standpipe (11), and by the guide wheel (9) that is contained in both sides, standpipe (11) front and back by support (10) with two loop tensionings.In center tap (5) left end retainer position spacing ring shelves (4) are housed.Chain drum-flywheel (12) is sleeved on the inboard that axis (3) is gone up right crank-flywheel (6).When the stressed rotation of crank-flywheel, axis (3) rotation also drives chain drum-flywheel (12) rotation, through the chain drive rear wheel.Simultaneously, power one side cable wire resets with the rotation tractive opposite side crank counter-rotating of crank-flywheel.The crank power corner equals the crank corner (embodiment is 120 °) that resets.The size of spacing ring shelves (4) the are adjustable corner that resets (throw of crank).
Claims (5)
1. reciprocating type transmission mechanism of bicycle of crank, it is characterized in that left and right crank-flywheel (1), (6) are contained in axis (3) two ends, link with the cable wire that resets (8) between the crank, be equipped with on bicycle profile tube and be used for tensioning the reset guide wheel (9) and the support (10) of cable wire (8), spacing ring shelves (4) are fixed in the center tap left side.
2. transmission mechanism of bicycle according to claim 1 is characterized in that respectively having on left and right crank-flywheel (1), (6) cylindrical and is used for connecting the cable wire (8) that resets and forms leading around lock-bit nail hole (2), (7) of the tractive loop that resets.
3. transmission mechanism of bicycle according to claim 1 and 2 is characterized in that having and is contained in both sides before and after the standpipe (11) by support (10) and is used for the reset a pair of guide wheel (9) in tractive loop of tensioning.
4. transmission mechanism of bicycle according to claim 1 is characterized in that chain drum-flywheel (12) is sleeved on the axis (3), is positioned at right crank-flywheel (6) inboard.
5. transmission mechanism of bicycle according to claim 1 is characterized in that being equipped with in center tap (5) left end retainer position and is used for limiting and the reset spacing ring shelves (4) of corner of adjust crank.
