Abstract
The utility model relates to a vehicle multi-gear speed-regulating device. A central shaft paralleled with each other and the ends of two splined shafts are arranged in a triangle shape in a gearbox. The central shaft is provided with a central double gear which can freely rotate, and both sides of the central shafts are provided with splined shafts. The splined shafts are respectively sheathed with a double gear which can be engaged with the central double gear and has an unequal diameter in sliding mode. The shift fork which is clamped between the two gear wheels and a spring are freely sheathed on a mandrel, the end of a speed-regulating flexible shaft passes through the gearbox body and is connected with the shift fork. The speed-regulating flexible shaft controlling the double gear is respectively engaged with the big gear and the pinion of the central double gear by the shift fork, and four advance gears and one reverse gear are arranged. The vehicle multi-gear speed-regulating device of utility model has the advantages of simple structure, smartness, portability, low cost, and convenient usage.
Description
Technical field
The utility model relates to a kind of vehicle speed regulation device, and particularly vehicle keeps off speed regulation device more.
Background technology
Human powered vehicles such as existing bicycle and three-wheel vehicle have only a kind of speed, run into upward slope, cyclist's go-cart of having to get off.Many fast mountain bikes have the sprocket wheel speed regulation device, but its price is higher; Existing motor bike and three wheeled motor car mostly do not reverse gear, and rely on manpower to promote reversing, and be very inconvenient.
The utility model content
The purpose of this utility model provides a kind of easy to use, and the cheap many retainings speed regulation device of reversing gear that has is used for manpower and power actuated vehicle.
The utility model is realized by following technical proposal: the end points of center shaft parallel to each other and two castellated shafts is triangularly arranged in gearbox body, the central dual gear that freely rotates is housed on the center shaft, in its both sides castellated shaft is housed, the dual gear that the suit that slides respectively can not wait with the engagement of central dual gear, diameter on castellated shaft.Be clipped in shift fork between two plate gears and spring freedom suit on axle, the termination of speed governing flexible axle is passed gearbox body and is connected with shift fork.The speed governing flexible axle can be respectively and the large and small gear or the reverse gear engagement of central dual gear by the fork controls dual gear, has four forward gears and one and reverse gear.If be used for the three wheeled motor car of existing a plurality of forward gears, can only adorn single forward gear gear and reverse gear, at this moment just have only a forward gear and one to reverse gear.If be used for bicycle, can not adorn reverse gear, at this moment just be not with and reverse gear, with simplified structure.Center shaft and castellated shaft in gearbox body, rely on the bearing cap shim location by bearing installation.Large and small sprocket wheel is contained in the castellated shaft end in gearbox body front or the back side outside respectively, by chain respectively with axle drive shaft and rear vehicle shaft on sprocket wheel be connected.
The vehicle that the utility model provides keeps off speed regulation device more and has simple in structure, small volume and less weight, advantage cheap, easy to use, is fit to be installed on bicycle, motor bike, manpower and the three wheeled motor car and uses.
