Can be provided with single or a plurality of side finishing bevel gear cuters on the described shell.
Described sprocket wheel can be the single or multiple lift chain sprocket structure.
Described axis left end is fixedly connected with screw.
Described shell left end is fixedly connected with screw.
The advantage of the utility model is: solving bicycle can only the unidirectional drive problem, and simple in structure, and noiselessness does not need to add in addition controller, and bicycle can free backward.
Description of drawings:
Fig. 1 is fixedly connected with the structural representation of screw for axis left end of the present invention;
Fig. 2 is fixedly connected with the structural representation of screw for shell left end of the present invention;
Wherein: 1, shell, 2, axis, 3, right finishing bevel gear cuter, 4, left angular wheel, 5, screw; 6, side finishing bevel gear cuter, 7, sprocket wheel, 8, clutch block, 9, spring, 10, steel ball; 11, steel ball, 12, steel ball, 13, steel ball, 14, steel ball, 15, screw; 16, screw, 17, screw, 18, side shaft, 19, crank.
The specific embodiment:
Below in conjunction with accompanying drawing and selected instance the utility model is done and to be further described:
As shown in Figure 1, side shaft (18) is captiveed joint with side finishing bevel gear cuter (6) (side shaft and side finishing bevel gear cuter also can be made of one structure), and screw (5) is fixedly installed on the side of shell (1), is provided with steel ball (14) between side shaft (18) and the screw (5); Left angular wheel (4) is installed on the left side of axis (2) through screw (17), between left angular wheel (4) and axis (2), is provided with steel ball (13); Right finishing bevel gear cuter (3) is installed on the right side of axis (2) through screw (15), between right finishing bevel gear cuter (3) and axis (2), is provided with steel ball (11), is provided with steel ball (10) between right finishing bevel gear cuter (3) and the shell (1); Sprocket wheel (7) is fixedly connected on the right finishing bevel gear cuter (3); Clutch block (8) is installed on the guide thread section at axis (2) middle part; Spring (9) is installed between clutch block (8) and the left angular wheel (4); Screw (16) is fixedly connected on the left end of axis (2), between screw (6) and shell (1), is provided with steel ball (12); Crank (19) is fixedly connected on the two ends of axis (2); Side finishing bevel gear cuter (6) respectively with the interlock mutually of left and right conical gear.
Principle of work: when adopting conventional forward to trample pedal driving bicycle; Crank (19) drives axis (2) forward rotation, and clutch block (8) moves to right-hand member along the guide thread on the axis (2), makes clutch block (8) and right finishing bevel gear cuter (3) closed contact; Produce propulsive effort; Make right finishing bevel gear cuter forward rotation, thereby drive sprocket wheel (7) forward rotation, bicycle is moved ahead; When oppositely trampling the pedal driving, crank (19) drives axis (2) backward rotation, and clutch block (8) moves to left end along the guide thread on the axis (2); Make clutch block (8) and left angular wheel (4) closed 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 drives sprocket wheel (7) forward rotation, and bicycle is still moved ahead.
Because clutch block (8) can only be separately and left or right finishing bevel gear cuter closed contact; When the right side or left angular wheel and clutch block (8) closed contact; Be positioned at the other end a left side or right finishing bevel gear cuter and axis (2) between do not produce propulsive effort; So when the bicycle backward, cycle chain also can take sprocket wheel backward rotation freely to.
As shown in Figure 2, the principle that shell (1) left end is fixedly connected with screw (16) is identical with the principle that Fig. 1 axis (2) left end is fixedly connected with screw (16).
In the above: the left and right sides of clutch block (8) can be provided with decorative pattern or groove and improve the friction force when contacting with the left and right conical gear; All steel balls are all replaceable to be that the bearing that adapts reduces installation difficulty; Also can save spring (9), be used for different needs.
Can be provided with single or a plurality of side finishing bevel gear cuters (6) on the shell among the present invention (1); Sprocket wheel can be the single or multiple lift chain sprocket structure occasion that meets the different needs.
