Abstract
The utility model relates to a front and back transmission case for a motor tricycle. The front and back transmission case for a motor tricycle comprises a machine shell, an input chain wheel, an output chain wheel, a main shaft, an input gear and an output gear. The input gear is movably connected with the main shaft. A transition shaft, a transition gear, an auxiliary shaft, and the back gear group of a back gear are arranged in the machine shell. The transition gear is meshed with the input gear. The back gear is a double-connection gear. One end of the back gear is meshed with the transition gear. The other end of the back gear can be meshed with the output gear. The utility model has the advantages of novel conception and simple structure. The front and back transmission case for a motor tricycle can be conveniently hung at the bottom of a motorcycle. The front and the back traveling of a vehicle can be controlled through a shift fork lever. The problems of the motor tricycle can be effectively solved. The front and back transmission case for a motor tricycle is the product of the new generation for like products.
Description
The utility model relates to a kind of transmission gearbox, particularly a kind of motor-tricycle just, the reverse drive case.
The three-wheel vehicle motor bike uses increasingly extensive as transportation means and car for disabled persons, existing motor-tricycle does not generally have reversing gear, inconvenient in actual the use, can not satisfy user's needs, the developing direction that to develop a kind of motor tricycle with reversing be this product.
The purpose of this utility model provide a kind of motor tricycle just, the reverse drive case.
The purpose of this utility model is achieved in that the utility model comprises casing, input, output chain gear, input gear, output gear, main shaft, and wherein input sprocket is fixed on the input gear, and input gear and main shaft are moving to be connect; But groove and projection that transferring power after the cooperation is arranged on input gear and the output gear, output gear can be along the slippages on main shaft of the key on the main shaft, and by the key transferring power.The reverse gearset that in casing, comprises transition axis, transition gear, countershaft, reverse gearwheel in addition, wherein transition axis, countershaft are fixed on the casing, transition gear is arranged on the transition axis, transition gear and input gear engagement, reverse gearwheel is arranged on the countershaft, reverse gearwheel is a dual gear, one end and transition gear engagement, and the other end can mesh with output gear.Shift fork also is housed on output gear, and shift fork can slippage on declutch shift shaft, and shifting fork bar is arranged on the shift fork.
The utility model has three work shelves, along shelves, neutral gear, reverse gear, stirs output gear by shifting fork bar drive shift fork and moves to different gears control on main shaft.During along shelves, shift fork is stirred output gear, and groove and projection on input, the output gear are matched, and makes power reach output chain gear by input sprocket, input gear, output gear, drives wheel by chain-driving, and vehicle is moved ahead; When reversing gear, shift fork is allocated to output gear and the reverse gearwheel position engaged, power by input sprocket, input gear, transition gear, reverse gearwheel, output gear, make to output chain gear, make vehicle rollback; During neutral gear, output gear and input gear, reverse gearwheel do not match, and vehicle is motionless.
The utility model is novel, simple in structure, can carry additionally easily to motor bike bottom, by the shifting fork bar control vehicle just, reversing, solved the problem that motor-tricycle can't be moveed backward effectively, be the new generation product of like product.
Fig. 1 is an elevational cross-sectional view of the present utility model.
Fig. 2 is that cutaway view is looked on a left side of the present utility model.
Now in conjunction with the accompanying drawings the utility model is specified.
The utility model comprises casing 1, input sprocket 2, output chain gear 3, main shaft 4, and input gear 5, output gear 6 is characterized in that: described input sprocket 2 is fixed on the input gear 5, input gear 5 and 4 moving connections of main shaft; The groove and the projection that cooperate the back transferring power are arranged on input gear 5 and the output gear 6, and output gear 6 can be along the key on the main shaft 7, slippage on main shaft 4, and by key 7 transferring power; In casing 1, comprise transition axis 8, transition gear 9, countershaft 10 in addition, the reverse gearset of reverse gearwheel 11, wherein transition axis 8, countershaft 10 are fixed on the casing 1, transition gear 9 is arranged on the transition axis 8, transition gear 9 and input gear 5 engagements have reverse gearwheel 11 on the countershaft 10, reverse gearwheel is a dual gear, one end and transition gear 9 engagements, the other end can mesh with output gear 6.Shift fork 12 also is housed on output gear 6, and shift fork 12 can move on declutch shift shaft 13, and shifting fork bar 14 is arranged on it.Described key 7 is splines, also has locating bush 15 to install with convenient on housing 1.
