Abstract
The present invention discloses a kind of pair of gearbox four-wheel drive tractor, aim to provide it is a kind of realize that front-wheel is operated alone, front and rear four-wheel synchronously drives, four-wheel drive tractor before and after double gearboxes for being operated alone of trailing wheel, it includes vehicle body, installation the body forward structure front driving wheel being connected with front gear box and the rear drive sprocket being connected with rear axle assy installed in body tail.The present invention solves the problems, such as that tractor climbing capacity is poor, tyre slip under load, is particularly suited for the adverse circumstances such as mountain area, hillside fields, forestry, pasture, cross-country locality and uses.
Description
Technical field
It is to be related to a kind of pair of gearbox four-wheel drive tractor specifically the present invention relates to field of agricultural machinery.
Background technology
Wheeled tractor is that China rural area uses most common tractor, the two-wheeled of the main forward drive of traction thing at this tractor rear portion（Or single-wheel）Drive, its driving torque tends not to make full use of, and causes internal combustion engine ability to give full play to, the situation for " can not making out energetically " easily occur.And the most rugged and rough, steep slope and slippery paths of the road in rural area, if only forward drive
Often there is serious skidding in power, driving wheel so that Running Speed of Tractor reduction, and accelerates the abrasion of driving wheel tire, and ultimately resulting in tractor cannot move ahead.
At present, also there is the wheeled tractor of some front and rear asynchronous drivings, but, can not be synchronous during driving work before and after this tractor, in transport driving, the mutually stuck situation of the gear of driving device after often occurring, so that parts cross quick-wearing, it is difficult to speed change and operation, using highly inconvenient.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide it is a kind of realize that front-wheel is operated alone, front and rear four-wheel synchronously drives, four-wheel drive tractor before and after double gearboxes for being operated alone of trailing wheel.
To achieve the above object, the present invention is achieved by the following scheme：
Four-wheel drive tractor before and after a kind of pair of gearbox, including vehicle body, installed in the diesel engine of body forward structure, belt, clutch, gear, front gear box, transfer case, front propeller shaft, rear transmission gear box, inter-axle shaft, the rear axle assy of power are transmitted successively, also including installing the front driving wheel that be connected with front gear box of body forward structure and installed in body tail and rear axle assy company
The rear drive sprocket for connecing, described rear transmission gear box includes the I axles being connected with front propeller shaft, I axles are provided with driver pinion, and the driver pinion is engaged with the driven gear wheel on II axles, and the driven gear wheel is engaged with the speed governing gear wheel on III axles, speed governing little gear.
It is improved further, described speed governing little gear is between driver pinion and speed governing gear wheel.
It is improved further, described speed governing gear wheel, speed governing little gear are connected with gear shift fork.
It is improved further, described driven gear wheel or speed governing gear wheel is engaged with the back gear on reversing shaft.
Operation principle of the invention：Front gear box and rear transmission gear box have the gear of equal number in the present invention, before necessary during rear synchronous driving, make the transforming gear of front and rear gearbox into same gear, just can realize the driving of trailing wheel and front-wheel with linear velocity, i.e., front and rear synchronous driving.
There is prior art to compare, the present invention has the advantages that：
1. engine power utilization rate is high.The present invention outputs power to front driving wheel by front gear box, while rear drive sprocket can be output power to by rear transmission gear box, makes tractor synchronous driving before and after realizing, is prevented effectively from driving wheel skidding, gives full play to the driving torque of engine.
2. the life-span of tractor is extended.The present invention is synchronous before and after making to be driven, prevent rear transmission gear box it is stuck the occurrence of, reduce the abrasion of parts, extend the physical life of tractor.
3. carrying capacity is strong.The present invention possesses the synchronously driven pattern of front-wheel, trailing wheel, it is to avoid the generation of the skidding of single front-wheel drive, improves carrying capacity.
