Abstract
The utility model relates to a foot variable-speed motorcycle engine with reverse gear, which belongs to the technical field of motorcycles. The utility model is characterized in that a reversing shaft 19 is arranged between an intermediate shaft 7 and a driving shaft 9; the reversing shaft is provided with a steering gear 18 forming an interstice fit with the reversing shaft; the intermediate shaft 7 and the driving shaft 9 are respectively provided with a reversing driving wheel 17 and a reversing driven wheel 15 orderly engaged with the steering gear 18; the reversing driving wheel 17 forms a close fit with the intermediate shaft 7; the reversing driven wheel 15 forms an interstice fit with the driving shaft 9; the driving shaft 9 is provided with a reversing ratchet wheel 16 matched with the reversing driven wheel 15 to form a reversing transmission system.
Description
The utility model discloses a kind of pin speed changer motorcycle engine that has the reverse gear position, belong to the motorcycle design field.
Along with the raising of expanding economy and people's living standard, the popularization and application of motorcycle is increasingly extensive, and the motorcycle vehicle is variation more also, develop to vehicles such as passenger and freight tricycle and ATV four-wheel beach buggies from traditional two-wheel vehicle of riding instead of walk, and good market prospects.The motor that is used for passenger and freight tricycle and four-wheel beach buggy requires to have the reverse gear position so that use.But present domestic single cylinder motorcycle engine does not still have this kind structure, and the motorcycle engine that is used for the four-wheel beach buggy abroad all adopts hand, the two speed changes of pin to realize speed changes and forward-reverse, complex structure cost height, and operation inconvenience is difficult to popularize.If can on existing general single cylinder engine for motorcycle, design pin speed change reverse gear position, to improving the technology content of existing motorcycle engine, enlarge market sales volume and have immeasurable effect undoubtedly.
Goal of the invention of the present utility model provides a kind of pin speed change motor engine of band reverse gear position of simple in structure, highly versatile.
Technical characteristics of the present utility model be between jack shaft and the live axle design and installation reverse gear shaft, the steering gear that is Spielpassung with it is installed on reverse gear shaft, reverse gear driving wheel, reverse gear follower have been installed respectively on jack shaft and the live axle to be meshed with steering gear successively, reverse gear driving wheel and jack shaft are drive fit, reverse gear follower and live axle are Spielpassung, the reverse gear ratchet that cooperates with the reverse gear follower has been installed on the live axle has been constituted the reverse gear power train.
Selector gear of the present utility model has adopted the technological scheme that increases reverse gear ratchet shift fork, and shift cam and shift cam orientation plate are redesigned, and makes it to control the clutch of reverse gear ratchet.Its working principle is identical with known technology, repeats no more.
During the utility model work, when main shaft drives the jack shaft rotation, reverse gear driving wheel and jack shaft are drive fits, so the reverse gear driving wheel rotates with jack shaft, reverse gear driving wheel and steering gear are normal engagements, so steering gear also rotates, steering gear and reverse gear follower also are normal the engagements, so the reverse gear follower also rotates.When shift fork was stirred the reverse gear ratchet and combined the locking of reverse gear follower and live axle with the reverse gear follower, the live axle counter-rotating realized reversing.
The utility model has the advantages that low, the easy to operate applicability of the good cost of simple in structure, versatility is strong, can be the supporting use of various three-wheels or four-wheel motor cycle.
Figure of description 1 is a structure sectional view of the present utility model, and accompanying drawing 2 is speed changer structure unfolded drawings, and accompanying drawing 3 is position views of left box body reverse gear shaft.
Embodiment of the present utility model sees accompanying drawing 1,2,3.Among the figure: 1 cylinder head, 2 cylinder block, 3 piston rod crankshaft mechanisms, 4 main shafts, 5 clutches, 6 synchronizers, 7 jack shafts, 8 speed change gear groups, 9 live axles, 10 start axle, 11 bent axle gearbox casings, 12 driving sprocket wheels, 13 magnetogenerators, 14 distribution devices, 15 reverse gear followers, 16 reverse gear ratchets, 17 reverse gear driving wheels, 18 steering gears, 19 reverse gear shafts, 20 spring clips.The pin speed change motor engine of this band reverse gear position, by 1 cylinder head, 2 cylinder block, 3 piston rod crankshaft mechanisms, 4 main shafts, 5 clutches, 6 synchronizers, 7 jack shafts, 8 speed change gear groups, 9 live axles, 10 start axle, 11 bent axle gearbox casings, 12 driving sprocket wheels, 13 magnetogenerators, 14 distribution devices and selector gear constitute, between jack shaft 7 and the live axle 9 design and installation a reverse gear shaft 19, reverse gear shaft 19 is that the semiaxis that is embedded on the left box body is formed, and be the close-fitting merging between the casing seal ring is housed, the steering gear 18 that is Spielpassung with it is housed on reverse gear shaft 19, spacing fixing by spring clip 20.Reverse gear driving wheel 17, reverse gear follower 15 have been installed respectively on jack shaft 7 and the live axle 9 to be meshed with steering gear 18 successively, reverse gear driving wheel 17 and jack shaft 7 are drive fit, reverse gear follower 15 and live axle 9 are Spielpassung, the reverse gear ratchet 16 and 15 engagements of reverse gear follower that are spline fitted with it have been installed on the live axle 9 have constituted the reverse gear power train.Constitute the reverse gear selector gear in the groove of the shift fork embedding reverse gear ratchet 16 that links to each other with shift cam orientation plate in the selector gear.
Below structure of the present utility model is described in detail: a kind of pin speed change motor engine with the reverse gear position, by 1 cylinder head, 2 cylinder block, 3 piston rod crankshaft mechanisms, 4 main shafts, 5 clutches, 6 synchronizers, 7 jack shafts, 8 speed change gear groups, 9 live axles, 10 start axle, 11 bent axle gearbox casings, 12 driving sprocket wheels, 13 magnetogenerators, 14 distribution devices and selector gear constitute, the reverse gear shaft 19 that it is characterized in that between jack shaft 7 and the live axle 9 design and installation, the steering gear 18 that is Spielpassung with it is housed on reverse gear shaft 19, on jack shaft 7 and the live axle 9 reverse gear driving wheel 17 has been installed respectively, reverse gear follower 15 meshes with steering gear 18 successively, reverse gear driving wheel 17 and jack shaft 7 are drive fit, reverse gear follower 15 and live axle 9 are Spielpassung, the reverse gear ratchet 16 and 15 engagements of reverse gear follower that are spline fitted with it have been installed on the live axle 9 have constituted the reverse gear power train.
Another embodiment of the present utility model, reverse gear shaft 19 can adopt the axis of dual-gripper to constitute, to increase its intensity.This scheme is suitable for the high-power engine and uses.
