Description
Technical field
The utility model relates to field of agricultural machinery, specifically, relates to four-wheel drive tractor before and after a kind of pair of change speed gear box.
Background technology
Trac. is main farm power machine, can draw different farm implements and plough, sows, gathers in, transports crops etc.Difference according to the move mode of trac. can be divided into trac. track type tractor and wheel-tire tractor substantially.Just generally speaking, small-sized trac. mostly is wheel-tire tractor, and large-scale trac. mostly is track type tractor.
Wheel-tire tractor is that the most general trac. is used in China rural area, the traction owner at this trac. rear portion wants the forward two-wheeled that drives (perhaps single-wheel) to drive, its driving torque often can not take full advantage of, cause the combustion engine ability not give full play to, the situation of " energetically can not making out " easily occurs.And the road in rural area rugged and rough, steep slope and slippery path mostly, if only depend on forerunner's power, seriously skidding often appears in drive wheel, makes Running Speed of Tractor reduce, and has accelerated the wearing and tearing of drive wheel tire, finally causes trac. to move ahead.
At present, the wheel-tire tractor of some asynchronous drivings in front and back also appears, still, can not be synchronous when driving work before and after this trac., when transport driving, the gear of the rear driving device of frequent generation is stuck situation mutually, make parts cross quick-wearing, be difficult to speed change and operation, use extremely inconvenient.
Summary of the invention
For the shortcoming of prior art, the purpose of this utility model is to provide and a kind ofly realizes that front-wheel drives separately, front and back four-wheel driven in synchronism, trailing wheel drive separately two change speed gear boxs front and back four-wheel drive tractor.
For achieving the above object, the utility model is realized by following scheme:
four-wheel drive tractor before and after a kind of pair of change speed gear box, comprise vehicle body, be arranged on the diesel engine of body forward structure, the belt of transferring power successively, power-transfer clutch, gear, front gear box, auxiliary gear box, front propeller shaft, rear transmission gear box, rear propeller shaft, back axle assembly, also comprise front driving wheel that body forward structure is connected with front gear box and the rear drive sprocket that is connected body tail and is connected with back axle assembly are installed, described rear transmission gear box comprises the I axle that is connected with front propeller shaft, the I axle is provided with driver pinion, described driver pinion and the driven big gear wheel engagement that is arranged on the II axle, described driven big gear wheel and the speed governing big gear wheel that is arranged on the III axle, the engagement of speed governing miniature gears.
Be improved further, described speed governing miniature gears is between driver pinion and speed governing big gear wheel.
Be improved further, described speed governing big gear wheel, speed governing miniature gears are connected with the gear shift fork.
Be improved further described driven big gear wheel or speed governing big gear wheel and the reverse gearwheel engagement that is arranged on reverse gear shaft.
Principle of work of the present utility model: in the utility model, front gear box and rear transmission gear box have the gear of equal number, before and after the needs during driven in synchronism, before and after making, the transforming gear of change speed gear box becomes same gear, just can realize trailing wheel and front-wheel with the driving of linear velocity, i.e. the front and back driven in synchronism.
There is prior art to compare, the utlity model has following beneficial effect:
1. the engine power degree of utilization is high.The utility model outputs power to front driving wheel by front gear box, can output power to rear drive sprocket by rear transmission gear box simultaneously, makes trac. realize the front and back driven in synchronism, effectively avoids drive wheel to skid, and gives full play to the driving torque of driving engine.
2. extended the life-span of trac..Driven in synchronism before and after the utility model makes prevents the generation of the stuck situation of rear transmission gear box, has reduced the wearing and tearing of parts, has extended the practical life of trac..
3. carrying capacity is strong.The utility model possesses front-wheel, the synchronously driven pattern of trailing wheel, has avoided the generation of the skidding of single f-w-d, has improved carrying capacity.
