Background technology
Present ordinary bicycle, variable speed bicycle, manual tricycle etc. are forward and trample pedal wheel disk and drive and to go on type of drive; Easy fatigue in the time of so by bike; Ride for a long time and can cause physical disfigurement and discomfort, ache all over, and the quantity of the bi-directional drive bicycle in the daily life is almost nil; And complex structure must could be realized the backward of bi-directional drive and bicycle under the cooperation of controller.
Summary of the invention
The objective of the invention is to overcome existing technical matters, provide a kind of easily manufactured, the device that can realize the bicycle bi-directional drive simple in structure.
The technical scheme that the present invention adopted is:
A kind of reversible drive device for bicycle comprises the shell that is provided with axis and side shaft simultaneously, left angular wheel, right finishing bevel gear cuter; The side finishing bevel gear cuter, clutch block, spring, sprocket wheel; Crank is characterized by: the middle part of axis is provided with the guide thread section, and clutch block is installed on the guide thread section of axis; Left and right finishing bevel gear cuter is installed on the left and right sides of axis respectively; Spring is installed between clutch block and the left angular wheel; Crank is fixedly connected on the two ends of axis; Sprocket wheel and right finishing bevel gear cuter are fixedly connected; The side finishing bevel gear cuter is installed on the side shaft, and while and the interlock mutually of left and right conical gear.
Be provided with ball or bearing arrangement between said left and right finishing bevel gear cuter and the axis, be provided with ball or bearing arrangement between side finishing bevel gear cuter and the side shaft.
Can be provided with single or a plurality of side shafts and side finishing bevel gear cuter on the said shell.
Said sprocket wheel can be the single or multiple lift chain sprocket structure.
Said axis left end is fixedly connected with screw.
Said shell left end is fixedly connected with screw.
The invention has the advantages that: 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, side shaft; 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, screw, 19, crank.
The specific embodiment:
As shown in Figure 1, side shaft (5) is installed on the side of shell (1) through screw (18), and side finishing bevel gear cuter (6) is installed on the side shaft (5), is provided with steel ball (14) between side finishing bevel gear cuter (6) and the side shaft (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 shafts (5) and side finishing bevel gear cuter (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.
