Description
Technical field
The invention belongs to the transmission for vehicles technical field, be specifically related to a kind of motor automatic speed-changing system at riding type beam motorcycle.
Technical background
In order to improve convenience and the Security that motorcycle is driven, be important one side automatically by manually changing into its speed variator system.Existing motorcycle generally also adopts hand gear, there is following defective in hand gear: 1, oil consumption is big, engine power is utilized low: transfer speed change lever because vehicle need subtract throttle, hand clutch handle, pin in the process of moving during speed change, lose time, automobile running inertia is descended, treat to refuel again after the speed change, both oil consumption, loss engine power again can not effectively be utilized the inertia that travels of motorcycle.2, handling, Security and travelling comfort are poor: need use the hand clutch handle during hand gear, use the pin regulation stall, on complicated road surface, need ceaselessly back and forth operation, make easily that the driver is tired to cause traffic accident.Existing bel-drivenn stepless speed variator system uses on the pedal motorcycle now, only adapts to pedal motorcycle and uses.Existing bibliographical information is used for the chain-driven formula automatic speed-changing system on the motorcycle, the problem of its existence is the drive chain poor reliability, and drive mechanism is complicated, need take bigger gearbox space, cause that thereupon oil level increases, and brings a series of problems that influence engine performance such as engine high-temperature.
Summary of the invention
The objective of the invention is to deficiency at the automatic speed-changing system existence of existing belt driven type of motorcycle and chain-driven formula, a kind of automatic speed-changing system that is applicable to the riding type beam motorcycle motor is provided, adopt gear transmission, reduce gear stage, improve transmission efficiency, booster response is fast, reduces oil consumption, minimizing is to the influence of engine performance, safety and comfort.
Technological scheme of the present invention is as follows:
The motorcycle engine automatic speed-changing system comprises parts such as bent axle, main shaft, countershaft, middle low-speed centrifugal formula clutch, high-speed centrifugal clutch and driving gear.It adopts bent axle, main shaft, three grades of transmissions of countershaft.Middle low-speed centrifugal formula clutch is installed on the bent axle, and their low speed is connected with the bent axle spline respectively with the middling speed driven disc.The shell of middle low-speed centrifugal formula clutch has inside and outside gear ring, and with the planetary pinion engagement, planetary pinion is affixed with the middling speed driven disc again respectively.The drive splines cover of driving gear on the bent axle and middling speed driven disc connects as one, and is enclosed within involuntary speed reduction gear engagement on the main shaft with key.Key is with low-speed active gear on the main shaft, the low speed driven gear engagement of band one-way element on low-speed active gear and the countershaft, and the spline on the main shaft is equipped with the high-speed centrifugal clutch.The driven disc of high-speed centrifugal clutch is connected by the connecting sleeve external splines with high speed driving gear on the main shaft, and the high speed driving gear then is enclosed within high speed driven gear engagement on the countershaft with key.
This automatic speed-changing system is also installed a ball type overrunning clutch on the inner ring of middling speed driven disc inner spline housing, and the low speed driven gear on the countershaft with one-way element also be the ball type overrunning clutch.
The advantage that the present invention had is:
1, saves fuel oil, the power utilization height: this speed variator system is owing to adopted gear transmission between bent axle and main shaft, make automatic transmission structure become compact, and reduced gear stage, transmission efficiency is improved, and booster response is fast, can effectively utilize the power of motor, save fuel oil more than 10%, be specially adapted to riding type beam motorcycle and use.
2, effectively improved handling, the Security and the travelling comfort of motorcycle: just can control motorcycle when the row of various road surfaces as long as use this speed variator system to control throttle well, the driver controls easily, safety and comfort.
Description of drawings
Fig. 1 is the structural drawing of motorcycle engine automatic speed-changing system;
Embodiment
Referring to Fig. 1, this automatic speed-changing system is installed in the right big case and gearbox of motor.Its middle low-speed centrifugal formula clutch device fits on the engine crankshaft 1, and the low-speed centrifugal piece 3 in the clutch connects bent axle 1 by the internal spline of low speed driven disc 2.Centrifugal 5 interior circle by the drive splines cover of middling speed driven disc 6 of middling speed is sleeved on the bent axle 1, and rivets with the planetary pinion 7 on the clutch outer member 4.Middling speed driven disc 6 is connected to an integral body by the drive splines cover with driving gear 11.Planetary pinion 7 respectively with inside and outside gear ring 9,8 engagement of clutch outer member 4, wherein ring gear 9 connects ball type overrunning clutch 10 by the inner ring of the inner spline housing on the middling speed driven disc 6.Driving gear 11 meshes with the involuntary speed reduction gear 13 that key is enclosed within on the main shaft 12, goes back key on this main shaft 12 and is with low-speed active gear 18.Low speed driven gear 19 engagements of band ball type overrunning clutch 20 on low-speed active gear 18 and the countershaft 21.Also be combined with the high-speed centrifugal clutch on the main shaft 12, its clutch housing 14 combines with main shaft 12 splines, the driven disc of high-speed centrifugal clutch combines with the external splines of high speed driving gear 16 connecting sleeves, and high speed driving gear 16 meshes with the high speed driven gear 17 that key is enclosed within on the countershaft 21.
The working procedure of this speed variator system:
1, when engine speed is lower than 1500r/min, the low-speed centrifugal piece 3 of middle low-speed centrifugal formula clutch does not overcome the elastic force of spring, the race of engine, and speed variator system is not worked.
2, when engine speed greater than 1500r/min during less than 3000r/min, the elastic force that the low-speed centrifugal piece 3 of clutch overcomes spring combines with clutch outer member 4, clutch outer member 4 drives planetary pinion 7 rotations by external toothing 8, planetary pinion 7 drives driving gear 11 by ring gear 9, this moment is because there is the decelerating effect of planetary pinion 7, the rotating speed of driving gear 11 changes, turn to also and change, and driving gear 11 is movable the cooperation with bent axle 1, for guaranteeing to turn to the ad hoc ball type overrunning clutch 10 of having counted, make driving gear 11 keep original turning to, transmission involuntary speed reduction gear 13 successively then, main shaft 12, low-speed active gear 18, low speed driven gear 19, countershaft 21, last power passes to trailing wheel, and motorcycle is in the low speed driving state.When engine speed speed under lower-speed state rose, the strength that centrifugal 5 of middling speed overcomes spring combined with clutch outer member 4, and after this planetary pinion 7 is not worked, and power is pressed same path, front and exported by 1: 1 ratio, and this is a middling speed.
3, when the rotating speed of motor during greater than 3000r/min, centrifugal 15 of the high-speed centrifugal clutch overcomes spring force and combines with clutch outer member 14, the high-speed centrifugal clutch drives high speed driving gear 16, high speed driving gear 16 drives high speed driven gear 17, because the speed of high speed driven gear 17 is higher than the speed of low speed driven gear 19, for fear of the twin-stage transmission, ball type overrunning clutch 20 in the low speed driven gear 19 works, under the effect of ball type overrunning clutch 20, low speed driven gear 19 can not slide driving action, power at a high speed transmits high speed driven gear 17 by high speed driving gear 16, pass to countershaft 21 again to trailing wheel, this is at a high speed.
