The technical scheme that the utility model adopts is:
A kind of bidirectional driving apparatus comprises shell, axis, and left angular wheel, right finishing bevel gear cuter, the side finishing bevel gear cuter, side shaft, 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 respectively the left and right sides of axis; Spring fitting is between clutch block and 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 be installed on the side shaft and respectively with the interlock of left and right conical gear phase.
The two ends of described shell are provided with the axle bowl; The left side of clutch block is provided with the clutch block joint, and an end of spring is installed on the clutch block joint, is provided with bearing arrangement between side finishing bevel gear cuter and the side shaft.
Described sprocket wheel can be the single or multiple lift chain sprocket structure.
The utility model has the advantage of: solving bicycle can only the unidirectional drive problem, and simple in structure, does not need to add in addition controller, and bicycle can free backward.
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 block, 6, the side finishing bevel gear cuter, 7, sprocket wheel, 8, spring, 9, the clutch block joint, 10, side shaft, 11, screw, 12, the silk gear, 13, axle bowl, 14, silk gear, 15, the silk gear, 16, silk gear, 17, crank, 18, 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); Silk gear (12) is installed on the side shaft (10), be provided with steel ball (18) between side shaft (10) and the side finishing bevel gear cuter (6), make side shaft 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 angular wheel (4) keeps off the left side that (15) are installed on axis (2) by silk, is provided with steel ball (18) between left angular wheel (4) and axis (2); Right finishing bevel gear cuter (3) is installed on the right side of axis (2) by silk gear (14), between right finishing bevel gear cuter (3) and axis (2), be provided with steel ball (18), the two ends of shell (1) are provided with axle bowl (13), are provided with steel ball (18) between right finishing bevel gear cuter (3) and the axle bowl (13); Sprocket wheel (7) is fixedly connected on the right finishing bevel gear cuter (3); Clutch block (5) is installed on the guide thread section at axis (2) middle part; Clutch block joint (9) is installed on the left end (the clutch block joint also can be made of one structure with clutch block and simplify production) of clutch block (5); One end of spring (8) is installed on the clutch block joint, and the other end contacts with left angular wheel (4); Silk gear (16) is fixedly installed in the left end of axis (2), is provided with steel ball (18) between silk gear (16) and axle bowl (13); Crank (17) 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 (17) drives axis (2) forward rotation, clutch block (5) moves to right-hand member along the guide thread on the axis (2), make clutch block (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 (17) drives axis (2) backward rotation, clutch block (5) moves to left end along the guide thread on the axis (2), make clutch block (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.
Because clutch block (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 block (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 block (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) were provided with the ball trajectory, 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 be the single or multiple lift chain sprocket structure occasion that meets the different needs.
