The utility model has the advantages that: gear driving bicycle is rational in infrastructure, is skillfully constructed, novelty, and gear transmission meshes in order, and stable drive is installed, convenient disassembly.
Description of drawings
Accompanying drawing 1: gear driving bicycle drive mechanism figure;
Accompanying drawing 2: gear driving bicycle ratchet structure section-drawing;
Accompanying drawing 3: gear driving bicycle shell scheme drawing.
Among the figure: (1) conical gear; (2) conical gear; (3) chain stay pipe; (4) transmission shaft; (5) rear axle housing; (6) conical gear; (7) conical gear (ratchet fuse); (8) ratchet; (9) ratchet shell; (10) rear drum tube; (11), (15), (33) steel bowl; (12), (14), (17), (18), (32) steel ball; (13) jam nut; (16), (19), (34) axle bumper; (20) rear axle; (21) axis; (22) crank pin; (23) crank; (24), (25), (26) joint; (27) center tap; (28), (29) shell; (30) cylindrical shell; (31) gap; (32) jump ring.
Below in conjunction with drawings and Examples technical scheme described in the utility model is described in further detail.
Embodiment
Referring to accompanying drawing 1, foot-operated crank (23) is just changeing conical gear (1) forward, driving conical gear (2) just changes, driving conical gear (6) by transmission shaft (4) just changes, conical gear (6) drives conical gear (7) more just to be changeed, and conical gear (7) afterbody cylinder is provided with ratchet (8), inserts on the tooth uniform in the ratchet shell (9), driving rear drum tube (10) just changes, and drive trailing wheel, bicycle drive and advance.
In the described technical scheme of this case, adopt spline to connect the conical gear (2) and the conical gear (6) at transmission shaft (4) two ends, increased the axial action radius of transmission shaft (4), be convenient to install and adjustment.Be provided with steel bowl (11), (15) supporting at transmission shaft (4) two ends.Because in the trajectory that the concave surface of the concave surface of steel bowl (11) and conical gear (2) afterbody forms with in the trajectory of the concave surface formation of steel bowl (15) and conical gear (6) afterbody, be equipped with steel ball (12), (14).Rear axle (20) is provided with axle bumper (16), (19), (34), in the trajectory that the concave surface at its concave surface and conical gear (7) two ends, steel bowl (33) concave surface form, is provided with steel ball (17), (18), (32).So transmission shaft (4) is big with rear axle (20) setting range, stable drive, noise is little.
Referring to accompanying drawing 1, in the described technical scheme of this case, rear axle (20) is provided with conical gear (7), and its afterbody cylinder is the ratchet fuse.
Referring to accompanying drawing 2, on conical gear (7) the tail end cylinder, be arranged with ear shape groove in the center of circle being, ratchet (8) places in the ear shape groove, jump ring (32) is stuck in the groove of being opened downwards by the top in the middle of the ratchet (8), inwardly pressing the afterbody of ratchet (8), ratchet (8) top is outwards opened all the time, be close on the tooth in the ratchet shell (9).In the described technical scheme of this case, ratchet (8) is two, is symmetricly set on the ratchet fuse (7), the ratchet number of ratchet shell (9) is an odd number, like this, and when ratchet and half ratchet of ratchet relative displacement, must there be a ratchet to work, have reduced the neutral gear sense when travelling by bike.When the other end of ratchet shell (9) is provided with M35 * 1 screw thread and is threaded the bicycle cruising with rear drum tube (10), pin is not stepped on crank (23), all driving device is stopped action, because the unidirectional action of ratchet, ratchet (8) skids, ratchet shell (9) drives rear drum tube (10), and trailing wheel can rotate forward, becomes to slide shape.
Foot-operated crank (23) is when reversing backward, and whole transmission device is reversed, because the unidirectional action of ratchet, ratchet (8) skids, and not driving ratchet shell (9) is trailing wheel, and trailing wheel still rotates by original rotation direction.
As the trailing wheel reversing, promptly ratchet (8) and ratchet shell (9) engagement drive whole transmission device and reverse to reversing sense, drive two cranks (23) reversing.
Referring to accompanying drawing 3, in the described technical scheme of this case, transmission shaft (4) is installed in the chain stay pipe (3); Conical gear (2), steel bowl (11), steel ball (12), conical gear (6), steel bowl (15), steel ball (14) are installed in chain stay pipe (3) two ends and chain stay pipe (3) respectively and make in the joint (24) of one, (25); Backshaft transmission device comprises: conical gear (7), axle bumper (16), axle sleeve (5) are installed in circular cylindrical shell (30) lining that has the back fluting.During installation, rear axle (20) is pushed forward into by gap (31), during dismounting, withdraws from backward.
