Description of drawings:
Fig. 1 is a kind of structural representation of the present invention;
Wherein: 1, shell, 2, axis, 3, right finishing bevel gear cuter, 4, left angular wheel, 5, clutch cover, 6, the side finishing bevel gear cuter, 7, sprocket wheel, 8, spring, 9, pad, 10, side shaft, 11, screw, 12, the lateral filament gear, 13, axle bowl, 14, right silk gear, 15, left silk gear, 16, crank, 17, steel ball.
The specific embodiment:
Below in conjunction with accompanying drawing and selected example the utility model is described further:
As shown in Figure 1, side shaft (10) is installed on the shell (1), and fixes by screw (11) and shell (1); Lateral filament gear (12) is installed on the side shaft (10), be provided with steel ball (17) between side shaft (10) and the side finishing bevel gear cuter (6), make side finishing bevel gear cuter (6) can rotate freely around side shaft that (side shaft also can be made of one structure with the side finishing bevel gear cuter or be fixed together, and between side shaft and shell, be provided with bearing arrangement, be used for different the needs); Left and right finishing bevel gear cuter is installed on respectively the left and right sides of axis (2); Left silk gear (15) is fixedly installed in the axis left end and is positioned at left angular wheel (4) left side, and right silk gear (14) is fixedly installed in the axis right-hand member and is positioned at right finishing bevel gear cuter (3) right side; The two ends of shell (1) are provided with axle bowl (13), be provided with steel ball (17) between left and right finishing bevel gear cuter and left and right silk gear, left silk gear (15) and right finishing bevel gear cuter (3) are provided with steel ball (17) with axle bowl (13) respectively, and sprocket wheel (7) is fixedly connected on the right finishing bevel gear cuter (3); Clutch cover (5) is installed on the guide thread section at axis (2) middle part, and the left end of clutch cover (5) is provided with pad (9); The two ends of spring (8) respectively clutch cover (5) contact with left angular wheel (4); Crank (16) is fixedly connected on the two ends of axis (2); Side finishing bevel gear cuter (6) respectively with the interlock of left and right finishing bevel gear cuter phase.
Principle of work: when adopting conventional forward to trample pedal driving bicycle, crank (16) drives axis (2) forward rotation, clutch cover (5) moves to right-hand member along the guide thread on the axis (2), make clutch cover (5) and right finishing bevel gear cuter (3) close contact, produce propulsive effort, make right finishing bevel gear cuter forward rotation, thereby band movable sprocket (7) forward rotation moves ahead bicycle; When oppositely trampling the pedal driving, crank (16) drives axis (2) backward rotation, clutch cover (5) moves to left end along the guide thread on the axis (2), make clutch cover (5) and left angular wheel (4) close contact, produce propulsive effort, make left angular wheel (4) backward rotation, left angular wheel (4) drive side finishing bevel gear cuter (6) rotates, side finishing bevel gear cuter (6) drives right finishing bevel gear cuter (3) forward rotation, thereby band movable sprocket (7) forward rotation still moves ahead bicycle.
In this example because this example clutch cover (5) can only be separately and a left side or right finishing bevel gear cuter close contact, when the right side or left angular wheel and clutch cover (5) close contact, be positioned between left or right finishing bevel gear cuter and the axis (2) of the other end and do not produce propulsive effort, so when the bicycle backward, cycle chain also can take freely backward rotation of sprocket wheel to.
In the above: the friction force that the left and right sides of clutch cover (5) can be provided with decorative pattern or groove when improving with the left and right conical Gear Contact; All steel balls are all replaceable to be come for different needs for the bearing that adapts reduces installation difficulty; When the two ends of shell (1) are provided with the ball trajectory or shell (1) and left silk gear (15) and right finishing bevel gear cuter (3) when being provided with bearing, axle bowl (13) also can save to simplify production.
Can be provided with single or multiple side finishing bevel gear cuters (6) on the shell among the present invention (1); Sprocket wheel can (can be used for variable speed bicycle such as the multi-layer chain wheel construction for the single or multiple lift chain sprocket structure also can be gear structure; Can be used for without chain during gear structure
The bar bicycle) occasion that meets the different needs.
