Abstract
The utility model provides a transmission bicycle driven by a transmission thill fan, comprising a frame (1), a back wheel (10), which is characterized in that a rotary support shafts (2), (19) are arranged on the frame; two transmission thills (5), (6) with treadings are arranged on the rotary support shafts (2), (19); a chain disc transmission mechanism (7) is arranged on the rotary support shafts and the back wheel. The utility model improves the relations between the transmission thill and the force direction and the working effect and is labor-saving.
Description
Technical field:
The utility model is relevant with the manpower bicycle, and is special relevant with transmission bar fan-shape driving type manpower bicycle.
Background technology:
Existing bicycle such as bicycle or three-wheel vehicle all are that transmission bar wants period run to walk, and its transmission bar is braked Rotate 180 °, and the power that presses down must have too that wide-angle departs from the vertical transmission bar that acts on, and causes use not good, can not utilize power efficiently.
The content of utility model:
The purpose of this utility model is in order to overcome above deficiency, a kind of ride light, labour-saving transmission bar fan-shape driving type manpower bicycle to be provided.
The purpose of this utility model is achieved like this:
The utility model transmission bar fan-shape driving type manpower bicycle comprises vehicle frame (1), hind axle (10), it is characterized in that rotating fulcrum is arranged on the vehicle frame (2,19), be contained in respectively and contain foot-operated transmission bar (5,6) on the rotating fulcrum (2,19), on rotating fulcrum (2,19) and hind axle, chain drum transmission device (7) is arranged.
Above-mentioned chain drum transmission device (7) comprises the chain drum (8,9) that is loaded on respectively on the rotating fulcrum (2,19), is loaded on the hind axle respectively by chain (13,14) and chain drum (8,9) bonded assembly chain drum (11,12).
Free-wheel clutch (15,16) is housed between above-mentioned chain drum (11,12) and hind axle.
Fixed pulley (17) is arranged on the above-mentioned vehicle frame, and the two ends that are enclosed within the stay cord (18) on the fixed pulley are connected with transmission bar (5,6) respectively, finish the mode that transmission bar replaces with stay cord.
Referring to Fig. 1, Fig. 2, when riding the utility model, riding before the foot-operated transmission bar, transmission bar is made the chain drum on fan-shaped rotation drive of the cycle rotating fulcrum, and fan-shaped rotation makes hind axle, trailing wheel rotation that manpower bicycle such as bicycle or three-wheel vehicle are moved ahead by the chain drum rotation that chain drives on the hind axle.
The utility model improved transmission bar and power to relation and action effect.It is light, laborsaving to ride.
Description of drawings:
Fig. 1 is the utility model bicycle structure scheme drawing.
Fig. 2 is the utility model three-wheel vehicle structural representation.
