Description
Technical field
The utility model relates to motorcycle accessories, is specifically related to be used for the gear reversing device of three-wheel or four-wheel motor cycle.
Background technology
Early stage motor-tricycle does not have gear reversing device, can only can not fall back to overtake, uses inconvenient.In order to address this problem, people have designed multiple motor-tricycle gear reversing device.As the patent No. of on August 30th, 2000 bulletin be 99249675.6, name is called the Chinese patent of " motor-tricycle gear reversing device ", this device comprises housing, input shaft, axle shaft, tween drive shaft and driving chain wheel, on input shaft, be provided with two free gears, be provided with the power wheel of being with the slippage inner gear between two free gears, be contained on the motor-tricycle back axle, can realize the reverse gear function, but structure is comparatively complicated, volume is big, weight is heavier, driving efficiency is poor, and noise is big.So occurred component location guide finishing bevel gear cuter on the motor cycle engine output shaft again, directly with another castellated shaft on two the no key conical gears engagements of assembling, and between two conical gears installation can with the gear reversing device of any unidirectional chimeric power-transfer clutch of no key finishing bevel gear cuter.This apparatus structure compactness, installation and maintenance convenience, but engaged transmission is not steady, noise is bigger, when casing was the founding foundry goods, external form was coarse, and weight is bigger; When casing was the die casting aluminum component, intensity was not high, and very easily drawing crack damages.Analyze after deliberation, due to the helical angle that discovery engaged transmission reason not steady, that noise is bigger is a conical gear is less.
Summary of the invention
The purpose of this utility model provides a kind of motor bike gear reversing device, and its compact conformation, engaged transmission is steady, noise is little, and intensity is higher, is applicable to motor-tricycle or four-wheel motor cycle.
Motor bike gear reversing device described in the utility model, comprise casing, the double end castellated shaft that cooperates with casing both sides axis hole, sky is enclosed within driven suitable shelves conical gear and the driven reverse gear conical gear on the double end castellated shaft, cooperate and the power-transfer clutch between driven suitable shelves conical gear and driven reverse gear conical gear with the double end castellated shaft, the shift fork that cooperates with the annular groove at power-transfer clutch middle part, be located at double end castellated shaft vertical direction and stretch into the active conical gear of the engine output shaft end in the casing, initiatively conical gear and driven suitable shelves conical gear and the engagement of driven reverse gear conical gear, the fan-shaped clutch slot that the clutch that the power-transfer clutch two ends are provided with is carved up on the left of the other and driven suitable shelves conical gear and driven reverse gear conical gear right side is provided with is corresponding, shift fork is connected with selector device, and the right-hand member of double end castellated shaft connects firmly with the back axle castellated shaft is flexible.When shift fork is stirred power-transfer clutch to the right, the clutch pawl of power-transfer clutch right-hand member engages with driven fan-shaped clutch slot along shelves conical gear left side, a double end castellated shaft and a driven suitable shelves conical gear rotate synchronously, and driven reverse gear conical gear dallies on the double end castellated shaft, and motor bike to overtake; When shift fork is stirred power-transfer clutch left, the clutch pawl of power-transfer clutch left end engages with the fan-shaped clutch slot on driven reverse gear conical gear right side, double end castellated shaft and driven reverse gear conical gear rotate synchronously, and a driven suitable shelves conical gear then dallies on the double end castellated shaft, and motor bike is then drawn back.In order to make its engaged transmission steady, reduce noise, active conical gear, driven pitch angle alpha will along shelves conical gear and driven reverse gear conical gear are enlarged to 12-18 °, pitch angle alpha will be 15 ° best.
The casing of described motor bike gear reversing device is the die casting aluminum component, and the casing outside also is provided with connected connecting panel, and casing and connecting panel connect as one, and connecting panel is connected with vehicle frame with engine case again.Like this, both improved the intensity of casing, and can make its installation reliable and stable again.
The utility model has been owing to increased initiatively conical gear, driven pitch angle alpha will along shelves conical gear and driven reverse gear conical gear, and engaged transmission steadily when making gear shift, noise reduces greatly.In addition, also have compact conformation, casing intensity height, the reliable and stable advantage of installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is driven organigram along the shelves conical gear.
The specific embodiment
Referring to Fig. 1 and Fig. 2, engine output shaft 7 to be packed in the casing 1, pitch angle alpha will is the end that 15 ° active conical gear 8 is contained in engine output shaft 7; Power-transfer clutch 5 is contained in the middle part of double end castellated shaft 2, and pitch angle alpha will is that 15 ° driven is enclosed within the right of double end castellated shaft 2 along shelves conical gear 3 skies, and the fan-shaped clutch slot 10 in its left side is corresponding with the clutch pawl 9 of power-transfer clutch 5 right-hand members; Pitch angle alpha will is the left side that 15 ° driven reverse gear conical gear 4 skies are enclosed within double end castellated shaft 2, and the fan-shaped clutch slot 10 on its right side is corresponding with the clutch pawl 9 of power-transfer clutch 5 left ends; Then, will case in the body 1, and make driven along a shelves conical gear 3, driven reverse gear conical gear 4 and initiatively conical gear 8 engagements with upper-part.The lower end of shift fork 6 is cooperated with the annular groove at power-transfer clutch 5 middle parts, and the upper end of shift fork 6 is connected with steering unit.Casing 1 is connected with connecting panel 11, and connecting panel 11 is connected with vehicle frame with engine case.The right-hand member of double end castellated shaft 2 got final product with flexible the connection firmly of back axle castellated shaft.When shift fork is stirred power-transfer clutch to the right, the clutch pawl of power-transfer clutch right-hand member engages with driven fan-shaped clutch slot along shelves conical gear left side, a double end castellated shaft and a driven suitable shelves conical gear rotate synchronously, and driven reverse gear conical gear dallies on the double end castellated shaft, and motor bike to overtake; When shift fork is stirred power-transfer clutch left, the clutch pawl of power-transfer clutch left end engages with the fan-shaped clutch slot on driven reverse gear conical gear right side, double end castellated shaft and driven reverse gear conical gear rotate synchronously, and a driven suitable shelves conical gear then dallies on the double end castellated shaft, and motor bike is drawn back.
