Figure (2) is another example structure schematic diagram of the utility model.
Figure (3) is figure (1), the neutral gear of figure (2) embodiment, the constructional drawing of one grade of Weight type roller overrunning clutch.
Figure (4) is second gear, the third gear Weight type roller overrunning clutch constructional drawing of figure (1), figure (2) embodiment.
One, neutral gear
In the example structure principle shown in the figure (1), variable-speed drive is that a kind of sun tooth is fixed, and gear ring is a driving link, and pinion carrier is the reducing transmission structure of Passive part, uses to bring synchronously and realizes the remote driving of parallel axes.The rotating speed of driving engine be by bent axle (7) drive with its in hollow shaft (6) rotation of star-wheel (8) of meshing neutral gear Weight type roller overrunning clutch, owing to be connected with spline between star-wheel and the hollow shaft, and the swivel becket (9) (10) that is installed in the star-wheel both ends of the surface, the cover plate (4) (5) of swivel becket outside, the roller that is connected with swivel becket (11), stir pin (43), the centrifugal cylindrical pin (40) that links to each other with two end cover plate (4) (5), be installed in centrifugal (37) of star-wheel outside, and star-wheel with centrifugal between spring (38) composition one swivel.Centrifugal centnifugal force can not overcome the pressure of spring (38) when driving engine was in platform speed state, and centrifugal can not outwards be moved.Because roller (11) two axial ends in the angle of wedge that driving surface between star-wheel and the roller and outer shroud (2) are formed is inserted in respectively in the corresponding axis hole of swivel becket (45), its sway is subjected to swivel becket (9) (10) control, and the skewed slot of swivel becket (42) be inserted in centrifugal stir pin (43), so swivel becket is subjected to centrifugal control.During platform speed, roller (11) is in released state with outer shroud (2), and just the Weight type roller overrunning clutch does not transmit motor torque.
Two, starting
When engine speed increases, the centnifugal force of centrifugal (37) increases, when centrifugal centnifugal force increases to the pressure that can overcome spring (38), centrifugal is that outwards rotate in the axle center with the cylindrical pin, the pin (43) of stirring of the centrifugal other end also outwards moves simultaneously, because stirring the two ends of pin inserts respectively in the respective slots (42) of the rotating ring of walking around (9) (10), swivel becket is subjected to stirring the promotion of pin, angle of turning clockwise, the roller (11) that swivel becket will link to each other with it pushes in the angle of wedge that driving surface between star-wheel and the roller and outer shroud (2) formed, and roller (11) presses the driving surface between outer shroud (2) and star-wheel and the roller.Because star-wheel is a driving link, outer shroud is a Passive part, and the hand of rotation of star-wheel and angle of wedge direction are opposite sense, and star-wheel just compresses outer shroud by roller and drives the outer shroud rotation.The neutral gear power-transfer clutch is in bonding state and begins to transmit motor torque.
Because the outer shroud (2) of power-transfer clutch links into an integrated entity with bearing cover (1) (3), and the bearing cover of power-transfer clutch (1) links into an integrated entity with one grade of gear ring (32), the star-wheel of one grade of Weight type roller overrunning clutch (14) is connected with one grade of gear ring (32) with spline, when neutral gear clutch transmits motor torque, the star-wheel (14) of one grade of gear ring (32) and one grade of Weight type roller overrunning clutch also rotates together synchronously.The hollow shaft (35) of one grade of sun tooth (34) is screwed on shell, forming one grade of epicyclic gear transmission structure is to be driving link with the gear ring, pinion carrier is the reducing transmission structure of Passive part, and the rotating speed of driving engine is exported by pinion carrier (36) through one grade of planetary wheel (33) deceleration transmission.The outer shroud (28) of the one grade of Weight type roller overrunning clutch that is connected with pinion carrier (36) rotates synchronously with pinion carrier.Outer shroud (28) rotates by the outer shroud (20) that the synchronous band (15) meshing with it drives second gear Weight type roller overrunning clutch.Second gear gear ring (24) links into an integrated entity with outer shroud (20), and second gear epicyclic gear transmission structure is identical with one grade, all is that sun tooth (26) is fixing, and gear ring (24) is a driving link, and pinion carrier (27) is the reducing transmission structure of Passive part.The starting rotating speed of motor bike slows down through second gear planetary wheel (25) again, drives slowly starting by second gear pinion carrier (27) and the transmission shaft (16) meshing with it.
Three, gear shift is quickened
When the rotating speed of driving engine continued to increase, the rotating speed of the star-wheel of one grade of Weight type roller overrunning clutch (14) and then increased.One grade of Weight type roller overrunning clutch is identical with neutral gear Weight type roller overrunning clutch structure.It is to be installed in the swivel becket (13) (30) of star-wheel (14) both ends of the surface, with the outer cover plate (12) (31) of swivel becket, the roller that links to each other with swivel becket (29), the spring that stir pin, the centrifugal cylindrical pin that links to each other with two end cover plate, is installed between centrifugal of star-wheel outside and star-wheel and centrifugal is formed a swivel.Because star-wheel (14) is into a single integrated structure with one grade of gear ring (32), outer shroud (28) is into a single integrated structure with pinion carrier (36), so the rotating speed of star-wheel is higher than the rotating speed of outer shroud.Star-wheel is a driving link, and outer shroud is a Passive part.When the star-wheel rotating speed increases to centrifugal centnifugal force and can overcome the pressure of the spring between centrifugal and the star-wheel, centrifugal is that outwards rotate in the axle center with the cylindrical pin, the pin of stirring of the centrifugal other end also outwards moves simultaneously, because stirring the two ends of pin inserts in the respective slots of swivel becket (13) (30), swivel becket is subjected to stirring angle of promotion turning clockwise of pin, and the roller (29) that swivel becket will link to each other with it pushes in the angle of wedge that driving surface between star-wheel (14) and the roller (29) and outer shroud (28) formed.Roller (29) presses the driving surface between outer shroud and star-wheel and the roller.Because the rotating speed of star-wheel is higher than the outer shroud rotating speed, and the hand of rotation of star-wheel is opposite with angle of wedge direction, star-wheel just compresses outer shroud (28) by roller (29), and outer shroud and star-wheel are rotated synchronously, realizes that change-speed box enters second gear by one grade.
For the autoscooter of the driving of parallel axes, the teeth groove of the outer shroud of one grade of Weight type roller overrunning clutch be with meshingly synchronously, band (15) is mutually meshing with the teeth groove of the outer shroud of second gear Weight type roller overrunning clutch more synchronously, realizes the driving of parallel axes.
The structure of second gear power-transfer clutch also is a Weight type roller overrunning clutch structure.Different is that outer shroud (20) is a driving link, and star-wheel (17) is a Passive part.The outer shroud rotating speed is higher than the star-wheel rotating speed.So the angle of wedge direction that driving surface between star-wheel and the roller and outer shroud are formed and the hand of rotation of star-wheel are equidirectional.Star-wheel (17) links into an integrated entity with second gear pinion carrier (27).And for three class gear shift driving of parallel axes structure, pinion carrier is directly mutually meshing with transmission output shaft (16), so the rotating speed of second gear pinion carrier is subjected to directly influencing of load.The load of motor bike is little, and when mileage speed was higher, the rotating speed of the star-wheel (17) of second gear Weight type roller overrunning clutch was higher.Because centrifugal (46) are connected with the both ends of the surface cover plate (18) (23) of star-wheel (17) by cylindrical pin (50); Cover plate (18) (23) is fixed on the end face of star-wheel (17) by screw (51).When the rotating speed of star-wheel is higher, the centnifugal force of centrifugal (46) overcomes the pressure of spring (47), centrifugal is that outwards rotate in the axle center with cylindrical pin (50), the pin (49) of stirring of the centrifugal other end also outwards moves, because stirring the two ends of pin inserts respectively in the respective slots (48) of swivel becket, the promotion that swivel becket (19) (22) is subjected to the stirring pin angle that turns left, the roller (21) that swivel becket will link to each other with it pushes in the angle of wedge that driving surface between star-wheel and the roller and outer shroud (20) formed, roller compresses the driving surface between outer shroud (20) and star-wheel (17) and the roller, because the outer shroud rotating speed is higher than the star-wheel rotating speed, and angle of wedge direction is identical with the star-wheel hand of rotation, outer shroud (20) compresses star-wheel (17) by roller (21), and star-wheel just rotates synchronously with outer shroud.Realize that change-speed box enters third gear by second gear.
Four, moving back shelves slows down
When the motor bike load big, the moment deficiency, when perhaps chaufeur reduces mileage speed that throttle makes motor bike and reduces, star-wheel (17) rotating speed of second gear Weight type roller overrunning clutch also reduces thereupon, the centnifugal force of centrifugal (46) is not enough to overcome the pressure of spring (47), centrifugal is recovered the home position under the pressure of spring (47), the pin (49) of stirring on centrifugal spurs angle of swivel becket (19) (22) turning clockwise, the roller (21) that links to each other with swivel becket just breaks away from and the contacting of outer shroud (20) of Weight type roller overrunning clutch, the gear ring of second gear (24) just thoroughly separates with pinion carrier (27) like this, and third gear is just return second gear.If chaufeur is return platform speed position with throttle, because the rotating speed of driving engine is lower, star-wheel (8) rotating speed of neutral gear Weight type roller overrunning clutch is also along with being reduced to platform speed rotating speed, centrifugal (37) recover the home position under the effect of spring (38), the roller of power-transfer clutch (11) breaks away from outer shroud (2), power-transfer clutch thoroughly separates, and transmission system is return Neutral Position.
Principle according to the transmission of above-mentioned autoshift speed change, also the sun tooth of each speed threshold can be fixedly mounted on the same anchor shaft (52), one grade of pinion carrier (36) is connected with second gear gear ring (24), second gear pinion carrier (27) is connected with third gear gear ring (54), and the star-wheel of second gear, three-speed Weight type roller overrunning clutch is fixed on the planet cage plate of each grade by screw or rivet.Composition is by gear (53) and the mutually meshing input torque of engine crankshaft gear, by sprocket wheel (56) output that links to each other with third gear pinion carrier turning cylinder (55), the device of the autoshift speed change transmission of the crankshaft drive structure shown in figure (2).
The variation of the conversion energy automatic tracking motorcycle driving process medium velocity of the utility model gear has and performs rapidly, moves back shelves and adapts to a motor bike mileage speed automatically, makes motor bike can both obtain the torque and the speed of a motor vehicle of the best under the operating mode of any variation.Gear shift is fast steadily, make driving engine save fuel oil, and volume simple in structure is little, reliability and durability.It is current comparatively desirable a kind of fluid drive transmission.
