Bicycle driver of the present invention is installed movable pulley on straight-line motion mechanism; The movable end of the transmission rope of movable pulley upper sleeve through links pedal; Utilize movable pulley to save the manpower that scrunches pedal.Mechanism is simple, the efficient height.Use pedal guiding chain train that the motion of pedal is led, the application of force stage of pedaling keeps straight-line motion, and makes the circular movement buffering at the termination phase of pedaling, moves comfortable.The transmission rope that utilizes fixed pulley that follow-up pulley is drawn turns to, and can design various dissimilar bicycles according to the characteristics reasonable distribution straight-line motion mechanism and the locus of guiding mechanism on vehicle frame of rider.
Description of drawings
Fig. 1 is the structural representation of an embodiment of bicycle driver of the present invention.
Fig. 2 is the structural representation of the loop chain that has the side tooth of Fig. 1 embodiment.
The specific embodiment
The structure of an embodiment of bicycle driver of the present invention sees also Fig. 1.Similar with existing bicycle driver, left and right ratchet-gear wheel 2 is equipped with at imput shaft 1 two ends that it comprises respectively.The tooth of two straight-line motion mechanisms meshes with left and right ratchet-gear wheel 2 respectively, is connected with reverse link gear between two straight-line motion mechanisms, and two straight-line motion mechanisms link left and right pedal 10 respectively.Step on next pedal 10, make its cooresponding straight-line motion mechanism moving linearly and 1 rotation of cooresponding ratchet-gear wheel 2 drive imput shaft, another pedal 10 raises simultaneously.Alternately step on two pedals 10, the straight-line motion of pedal 10 changes into the continuous rotation of imput shaft 1.Different with existing bicycle driver is: on two straight-line motion mechanisms of bicycle driver of the present invention a movable pulley 5 is installed respectively.The movable end of the transmission rope 6 of each movable pulley 5 upper sleeve through links a pedal 10.Utilize movable pulley 5 to save the manpower that scrunches pedal 10.
The straight-line motion mechanism of an exemplary embodiments of bicycle driver of the present invention comprises that a flower wheel 4 and a subband have the loop chain 3 of side tooth.Loop chain 3 connects ratchet-gear wheel 2 and flower wheel 4.Movable pulley 5 is installed on the loop chain 3 on the linear portion between ratchet-gear wheel 2 and the flower wheel 4; In the process of ratchet-gear wheel 2 and flower wheel 4 coupled movements, movable pulley 5 keeps straight-line motions.
The reverse link gear of bicycle driver exemplary embodiments of the present invention comprises the side tooth 31 of the loop chain 3 side bands of a reversing wheel 14 and two straight-line motion mechanisms.Loop chain 3 laid parallels of two straight-line motion mechanisms, the side tooth 31 of side is relative, and is meshed with reversing wheel 14.Because transmission rope 6 is set on the movable pulley 5, the one end is fixed on the vehicle frame 7, and the other end links pedal 10.Step on next pedal 10, make movable pulley 5 moving linearlies of its cooresponding straight-line motion mechanism, and side tooth 31 displacements of cooresponding loop chain 3 side bands, the reversing wheel 14 that is meshed is rotated, thereby the loop chain 3 of the straight-line motion mechanism on opposite is subjected to the drive of the side tooth 31 reverse displacements of self, its movable pulley 5 is done the reverse linear motion, causes another pedal 10 to raise.
For making pedal 10 keep straight-line motion when scrunching, pedal 10 can be installed on the guiding mechanism.The common practice is: pedal 10 is installed on the guide block, and guide block is sleeved in the straight guide pin bushing.When pedal 10 stops in the process that scrunches, when guide block touches the end of guide pin bushing, stop suddenly, rider has uncomfortable feeling.For this reason, bicycle driver exemplary embodiments of the present invention also comprises two groups of pedal guiding chain trains that are installed on the vehicle frame 7.Each group pedal guiding chain train comprises two chain drums 12,13 and an inner loop chain 11; Pedal 10 is installed on the chain of linear portion between two chain drums 12,13.Pedal 10 keeps straight-line motion in the process of scrunching, and when the process that scrunches stopped, pedal 10 was done kicking motion along the excircle of chain drum 13, and rider can not feel to have impact, and pedaling is comfortable naturally.
Use bicycle for ease of various dissimilar riders, design engineer will be designed various dissimilar bicycles according to the characteristics reasonable distribution straight-line motion mechanism and the locus of guiding mechanism on vehicle frame of rider.Sometimes the transmission rope 6 that needs follow-up pulley 5 is drawn turns to, and bicycle driver exemplary embodiments of the present invention for this reason also comprises two groups of guiding fixed pulley systems that are installed on the vehicle frame.Every group of guiding fixed pulley system has a fixed pulley 8 at least; The transmission rope 6 that follow-up pulley 5 is drawn is guided pedal 10 into through the fixed pulley 8 of guiding fixed pulley system.
The structure of the loop chain that has the side tooth 3 of present embodiment sees also Fig. 2.There is a minor axis 301 in each joint of loop chain 3, axle sleeve 302 of the middle part suit of minor axis 301, connecting panel 303 and outside link plate 304 in the two ends of axle sleeve 302 are separately installed with, interior connecting panel 303 and outside link plate 304 are along direction extension on the contrary, the two ends riveted of minor axis 301, axle sleeve 302, interior connecting panel 303 and the outside link plate 304 that makes minor axis 301 upper sleeve throughs in the axial direction can not play, and can rotate around minor axis 301.Adjacent two joints of loop chain 3 or connect by interior connecting panel 303, or connect by outside link plate 304.The cavity that adjacent two joints are surrounded by axle sleeve 302, interior connecting panel 303 and outside link plate 304 supplies the tooth of ratchet-gear wheel to penetrate wherein, and axle sleeve 302 becomes loop chain 3 and ratchet-gear wheel ingear tooth in fact.Loop chain 3 one side outside link plates 304 outer middle side parts do that outward extending side tooth 31 is arranged, and side tooth 31 becomes meshing relation with reversing wheel.
