Abstract
The utility model relates to a formula bicycle drive arrangement is stepped on more, the device include one set by big sprocket (1), chain (2) and little sprocket (3) constitute with the unanimous transmission system of bicycle on the market, its characteristics are by big sprocket (7), cross chain (6), branch chain pulley (5) and little sprocket (4) constitute another transmission system. When the bicycle is pedaled anticlockwise, the small chain wheel (3) drives the bicycle rim to rotate; when the bicycle is pedaled clockwise, the small chain wheel (4) drives the bicycle rim to rotate. The device can enhance the climbing capability of the bicycle, improve the transmission efficiency, change the angle of the upper pedal and the lower pedal, also can drive at variable speed, change the pedal mode in turn, reduce the fatigue and have more comprehensive exercise on the waist and the legs.
Description
The utility model relates to a kind of transmission device that is specially adapted to bicycle or three-wheel vehicle.
Existing bicycle all has only a kind of mode that scrunches, and it is tired that rider is produced.The CN2055804U patent application discloses the bicycle bi-directional drive mechanism that a kind of name is called " the two-way device that steps of bicycle ", this bicycle has been realized can any forward and reverse conversion stepping and has been driven, reached a kind of medically effect of so-called " backward therapy ", also can make the speed of a motor vehicle that two kinds of variations are arranged simultaneously.But this bicycle has 5 sprocket wheels, and at least two sprocket wheel criteria of right and wrong parts wherein, and two sprocket wheels all require higher intensity and rigidity because of stressed big to associated axle and supporting in the middle of it.
The purpose of this utility model is that design a kind ofly can realize two-way stepping, the bicycle driving device that structure simply and is easily made and promoted again.
The utility model is achieved in that
A kind of many pedal-type bicycles actuating device, relate to footstep mechanism (8), hinge wheel (1), chain (2), minor sprocket (3), be characterized in that this actuating device also is provided with hinge wheel (7) parallel and coaxial with hinge wheel (1) and the minor sprocket (4) parallel and coaxial with minor sprocket (3), have a chain (6) to intersect and be placed on hinge wheel (7) and the minor sprocket (4).
Further scheme is that the infall of chain (6) is provided with branch chain block pulley (5).
Further scheme is, the line of centers of the pilled-in selvedge of the longitudinal plane of symmetry of hinge wheel (7) and minor sprocket (4) and intersection chain (6) at grade.
Because the utility model has adopted the intersection chain and divided chain block pulley, thereby has realized design goal well, the employing of this device simultaneously also can make the bicycle hill climbing ability strengthen.According to the difference of road conditions, the cyclist can have multiplely scrunch that mode is laborsaving to realize, speed change, efficient.
Fig. 1 is a constructional drawing of the present utility model.
Below in conjunction with Fig. 1 the utility model is described further.
As Fig. 1, a kind of many pedal-type bicycles actuating device, comprise footstep mechanism (8), be loaded on two identical hinge wheels (1 on the imput shaft, 7), be loaded on two identical minor sprockets (3,4) on the driven shaft, chain (2) is placed on hinge wheel (1) and the minor sprocket (3), and the driving system of the bicycle on this driving system and the existing market is as good as.Chain (6) " 8 " word intersection is placed in hinge wheel (7) and minor sprocket (4) is gone up another driving system of composition, the infall of chain (6) has a branch chain block pulley (5) that is fixed on the vehicle body that the pilled-in selvedge and the slack list of chain (6) are separated, in order to make bicycle labor saving, efficient, the longitudinal plane of symmetry of chain (6) pilled-in selvedge line of centers and hinge wheel (7) and minor sprocket (4) is kept at grade.
When rider's conter clockwise stepped, minor sprocket (3) and rear wheel did to advance rotation, minor sprocket (4) rotation of skidding.
When rider's cw stepped, minor sprocket (4) and rear wheel did to advance rotation, minor sprocket (3) rotation of skidding.
When the rider scrunches up and down, eliminated up and down two dead points of hinge wheel, driving torque increases, and it is more little to scrunch angle, and driving torque is big more, thereby hill climbing ability is strong, and realizes the purpose of speed change.
Claims (3)
1, a kind of many pedal-type bicycles actuating device, relate to footstep mechanism (8), hinge wheel (1), chain (2), minor sprocket (3), it is characterized in that this actuating device also is provided with hinge wheel (7) parallel and coaxial with hinge wheel (1) and the minor sprocket (4) parallel and coaxial with minor sprocket (3), have a chain (6) to intersect and be placed on hinge wheel (7) and the minor sprocket (4).
2, many pedal-type bicycles actuating device according to claim 1 is characterized in that the infall of chain (6) is provided with branch chain block pulley (5).
3, many pedal-type bicycles actuating device according to claim 2, it is characterized in that the longitudinal plane of symmetry of hinge wheel (7), minor sprocket (4) and intersect chain (6) pilled-in selvedge line of centers at grade.
