Abstract
The utility model relates to a transmission device for a jinrikisha, which is characterized in that a torsional spring can store and release energy through a rotating transmission teeth disc and a rotating unidirectional transmission wheel, so that the utility model is not only labour saving but also accelerating. The utility model is especially suitable for being arranged on the bicycles and the jinrikisha tricycles and used in the mountain areas and the hilly regions.
Description
The utility model relates to the driving device technical field of rickshaw, is particularly suitable for using on bicycle.
Existing bicycle and other rickshaws by chain gear, be to step on the axis of changing trains or buses by people's both feet, thereby the trailing wheel that is driven car by chain advances, people are when using this rickshaw, not only effort is big, and the speed of a motor vehicle is slow, although people have particularly done many-sided improvement on the transmission device of bicycle at rickshaw, all fail to solve can improve the speed of a motor vehicle again can the labour-saving problem.
The purpose of this utility model be the design a kind of can improve speed, again can the labour-saving transmission device for rickshaw.
Of the present utility model being characterised in that in a fixed cover is equipped with axle, torsion spring, transmission fluted disc and unidirectional power wheel are installed on this axle sleeve, this transmission fluted disc that is installed on the axle sleeve is in transmission connection with another unidirectional power wheel that can be installed on the rickshaw wheel shaft, and this unidirectional power wheel that is installed on the axle sleeve is in transmission connection with another transmission fluted disc that can be installed on the rickshaw axis.
The utility model is particularly suitable for being installed on bicycle and the manual tricycle, in the mountain area, the Qiu Ling area uses.During use, in the time of can when the car descending or by inertia, advancing,, make the torsion spring energy reserve, rely on the torsion spring release energy then, car is advanced by transmission by reversing car axis, can the laborsaving purpose that can quicken again thereby reach.
Embodiment shown in the accompanying drawing, can be installed on the bicycle and use, wherein Fig. 1 is the annexation scheme drawing of embodiment, and Fig. 2 is structure and the drive connection scheme drawing of embodiment, Fig. 3 is mounted in the structural representation of the unidirectional power wheel on the axle sleeve, and Fig. 4 is the structural representation of another unidirectional power wheel.
With reference to accompanying drawing, present embodiment has a fixed cover (14), has lid (15) on it, one (6) are installed in the fixed cover (14), be set with axle sleeve (7) on the axle (6), torsion spring (11), transmission fluted disc (10) and unidirectional power wheel (9) are installed on the axle sleeve (7), and described torsion spring (11) can be disc spring, and its two ends are separately fixed on axle sleeve (7) and the fixed cover (14).Described transmission fluted disc (10) is in transmission connection by chain (13) and another unidirectional power wheel (8), and this unidirectional power wheel (8) can be installed on the wheel shaft (12) of bicycle rear.The unidirectional power wheel (9) that is installed on the axle sleeve (7) is in transmission connection by chain (5) and another transmission fluted disc (4), and this transmission fluted disc (4) can be installed on the axis (1) of bicycle.Above-mentioned two unidirectional power wheels (9), (8) are ratchet, change the pawl structure, can directly select the flywheel of using on the bicycle for use.Above-mentioned two transmission fluted discs (4), (10) can be selected the chain wheel of using on the bicycle for use.
In the use, step step (3) and rotate the axis (1) of bicycle by leg (2) clockwise direction of bicycle, thereby driving unidirectional power wheel (9) by fluted disc (4) by chain (5) rotates, just work done when this unidirectional power wheel (9) only rotates in the clockwise direction drives axle sleeve (7) by it and rotates to tighten torsion spring (11).Just work done when another unidirectional power wheel (8) only rotates in the counterclockwise direction, when torsion spring (11) when releasing energy, promptly the wheel shaft (12) that makes this unidirectional power wheel (8) drive bicycle rear by transmission fluted disc (10), chain (13) rotates, thereby bicycle is advanced automatically.In the present embodiment, the radius of transmission fluted disc (4) is 1/4 of bicycle leg (a 2) length, the diameter of unidirectional power wheel (8) is 1/3 of transmission fluted disc (a 10) diameter, available less power tightens torsion spring (11) and makes it discharge bigger energy, and reaching can the laborsaving purpose that can quicken again.When using bicycle at ordinary times, it advances also can to use original actuator drives.
Claims (3)
1, a kind of transmission device for rickshaw, it is characterized in that in a fixed cover (14), being equipped with axle (6), torsion spring (11), transmission fluted disc (10) and unidirectional power wheel (9) are installed on the axle sleeve (7) of this axle (6), and this transmission fluted disc (10) that is installed on the axle sleeve (7) is in transmission connection with another unidirectional power wheel (8) that can be installed on the rickshaw wheel shaft (12); This unidirectional power wheel (9) that is installed on the axle sleeve (7) is in transmission connection with another transmission fluted disc (4) that can be installed on the rickshaw axis (1).
2,, it is characterized in that between unidirectional power wheel (9) and transmission fluted disc (4) and transmission fluted disc (10) and another the unidirectional power wheel (8) by chain gear according to the described transmission device for rickshaw of claim 1.
3,, it is characterized in that said torsion spring (11) is a disc spring according to claim 1 or 2 described transmission device for rickshaw.
