Abstract
The utility model relates to a differential continuously variable transmission for motorcycle, which is characterized in that a centrifugal clutch is shifted to a driving pulley axle; a jaw clutch is shifted from a differential to a newly added middle axle; meanwhile, a one-way clutch is added to a middle gear on the middle axle; and finally a chain transmission structure is adopted for transmission. The utility model improves the current transmissions, simplifies their structures, is convenient for maintenance, and reduces oil consumption. Therefore, the device is applicable not only to pedal motorcycles but also to bestriding motorcycles.
Description
Technical field
The utility model relates to a kind of motor bike differential type toric transmission.
Background technology
What extensively adopt on the known pedal motorcycle is v-belt stepless speed variator.This change-speed box has lot of advantages, but existing comparison distinct issues is oil consumption height, the motor bike that adopts this change-speed box power-transfer clutch when starting and low speed driving is in half hitch and closes state, just skid, in the driving process, the motor bike many places are in idling mode in the city, and this situation of skidding accounts for more than 50%, waste fuel on the one hand, also quickened the wearing and tearing of clutch facing on the other hand.The high Another reason of oil consumption is that change-speed box can cause engine rpm too high when driving engine is received throttle, and particularly when descending, non-refuelling is not walked, and has so just increased oil consumption.For this reason, Chinese patent 02257662.2 provides the pedal motorcycle differential type toric transmission of a kind of employing one shaft type box of tricks, though this patent has reduced oil consumption, yet exists complex structure, volume big, the problem of installation and maintenance trouble.
Summary of the invention
In order to solve the problem that exists in the above-mentioned background technology,, provide a kind of novel pedal motorcycle differential type toric transmission simple in structure, fuel-efficient by improvement to above-mentioned patented technology scheme.
Realize that the utility model purpose technical scheme is as follows:
Novel pedal motorcycle differential type toric transmission comprises V-shape belt stepless speed changing mechanism, a shaft type box of tricks, centrifugal clutch, dental clutch and three free-wheel clutchs, it is characterized in that:
The driving pulley axle of A, V-shape belt stepless speed changing mechanism is provided with reaction gear, be located on the tween drive shaft with reaction gear ingear intermediate gear 4, intermediate gear 4 is provided with free-wheel clutch 9, and the tween drive shaft opposite side is provided with intermediate gear 6 and dental clutch successively; Differential gear 7 engagements of an intermediate gear 6 and a shaft type box of tricks;
The differential axle of B, a shaft type box of tricks is provided with drive sprocket 10, and driven sprocket 17 is located on the rear vehicle shaft;
C, centrifugal clutch are located on the driven pulley axle 16 of V-shape belt stepless speed changing mechanism.
The utlity model has the beneficial effect of several respects:
1, the driving pulley axle of centrifugal clutch from the V-shape belt stepless speed changing mechanism moved on the driven pulley axle, because the rotating speed of driven pulley is higher than driving engine output, so the size that can dwindle centrifugal clutch, also can be general with present widely used pedal motorcycle centrifugal clutch.
2, dental clutch is moved on the tween drive shaft that increases newly from differential axle, make the differential assembly designs simplification, be convenient to maintenance, simultaneously, vehicle can not sent out and dash during start the engine, can not send out under the high situation of engine speed yet and dash.
3, chain gear is adopted in the final transmission of leading to rear vehicle shaft, so makes this change-speed box both be applicable to pedal motorcycle, also is applicable to straddle motor bike, also can make pedal motorcycle adopt the Independent Rear Suspension structure, improves damping performance.
4, adopt this change-speed box, vehicle is met engine off when descending the abrupt slope, can effectively utilize driving engine and lead the resistance braking.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment 1:
Novel pedal motorcycle differential type toric transmission comprises V-shape belt stepless speed changing mechanism, a shaft type box of tricks, centrifugal clutch, dental clutch 27 and three free-wheel clutchs 8,9,15.
On the driving pulley axle of V-shape belt stepless speed changing mechanism, be that reaction gear 3 is installed on the engine output shaft, be installed on the tween drive shaft 5 with reaction gear 3 ingear intermediate gears 4, intermediate gear 4 is provided with free-wheel clutch 9, and tween drive shaft 5 opposite sides are installed with intermediate gear 6 and dental clutch 27 successively; Differential gear 7 engagements of an intermediate gear 6 and a shaft type box of tricks.
On the differential axle 29 of one shaft type box of tricks drive sprocket 10 is installed, driven sprocket 17 is installed on the rear vehicle shaft 18.
Centrifugal clutch is installed on the driven pulley axle 16 of V-shape belt stepless speed changing mechanism, sees Fig. 1.
Behind the fire an engine, when rotating speed is lower than 1500 rev/mins, reaction gear 3 drives countershaft-gear 4, at this moment, tween drive shaft free-wheel clutch 9 dallies on tween drive shaft 5, when rotating speed surpasses 1500 rev/mins, power-transfer clutch hoof piece 28 is thrown away, combine with clutch drum 22, thereby drive driven pulley axle 16 and reduction pinion teeth 20 rotations, reduction pinion teeth 20 is through big or small reducing gear 14,19 and free-wheel clutch 15, power is reached planetary gear carrier big gear wheel 26, pass through planetary wheel 12 again, 25 pass to diff both sides crowngear 11,24, because left side crowngear 24 is motionless, the not starting as yet of vehicle this moment, right side crowngear 11 and rotate with its siamesed gear 7, can be drawn by the principle of work of diff: the rotating speed of gear 7 is two times of planetary gear carrier big gear wheel 26 rotating speeds, at this moment, power passes through gear 6 again, dental clutch 27, tween drive shaft 5, article free-wheel clutch 9, intermediate gear 4 is passed to reaction gear 3, realizes Jake brake.This braking is still effective when engine off, can make vehicle limit slip velocity when descending and engine off, guarantees driving safety.Rising along with engine speed, because the chronotropic action of V-shape belt stepless speed changing mechanism, the amplitude that planetary gear carrier big gear wheel 26 rotating speeds raise is greater than diff right side gear 7, the revolution ratio of the two by 1: 2 to transition in 1: 1, at this moment, differential axle 29 begins to rotate, outputting power, vehicle begins starting, the process that the revolution ratio of planetary gear carrier big gear wheel 26 and diff right side gear 7 changed to 1: 1 from 1: 2, promptly be Vehicle Speed from 0 to the most high-revolving stepless change process.
When fire an engine, handle need operate the clutch, make the dental clutch 27 on the tween drive shaft 5 be in released state, even engine speed is high more like this, vehicle can not sent out yet and dash, when engine off is carried out vehicle, dental clutch 27 is separated, otherwise it is motionless vehicle to be pushed away because of the resistance of driving engine.
