Abstract
The utility model relates to a walking tractor. Traditional walking tractors are totally driven by front wheels, and power efficiency is low. The utility model is characterized in that a rear drive transmission device is arranged between power output shafts of a headstock and rear wheels; the rear drive gearing device is composed of a plurality of transmission shafts and a plurality of universal devices, and each of the universal devices is arranged between two transmission shafts; as the universal devices can optionally change the direction, the problem that when a tractor goes around a turn, the transmission of power is difficult under the condition that the headstock and a carriage are not in the same direction, is solved; front drive is changed into front drive and rear drive, so power efficiency is improved; the cost of the utility model increases little.
Description
The utility model relates to a kind of walker tractor, the walker tractor that especially a kind of front and back wheel drives simultaneously.
Walker tractor both can be worn multiple farm machineries such as plough, rake, can wear conveying carriage again, thereby welcome by the peasant.But because traditional walker tractor is a f-w-d, when wearing the compartment as transportation means, tractive force is obviously not enough, and dynamic efficiency is low.
The purpose of this utility model is to improve the power transmission mode of walker tractor, changes f-w-d into front and back wheel and drives simultaneously, to improve dynamic efficiency.
Change f-w-d into front and back wheel and drive, need power be passed to trailing wheel by specific transmission device.Because driving engine (propulsion source) is installed in headstock, with front-wheel together, the transmission between driving engine and the front-wheel is easier to, when turning, headstock and compartment be not on same direction, so the transmission between driving engine and the trailing wheel is just much more difficult.
In order to solve headstock and compartment often not in unidirectional power transmission problem, the utility model uses several universal devices and some transmission shafts, by the universal device of takeoff output beam warp of headstock and transmission shaft power is passed toward trailing wheel.Because change of direction arbitrarily during the rotation of universal device, therefore, when car was turned, transmission shaft still can rotate conduction power.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of the walker tractor before improving;
Fig. 2 drives the walker tractor structural representation for the utility model front and back wheel;
Fig. 3 is each exploded view of drive transmission device behind the utility model.
See figures.1.and.2, the utility model comprises traditional headstock (100) and compartment (300), headstock (100) is provided with driving engine (110), front driving wheel (120,121) and handle handle (130), chassis Tuo Liang (310) front end in compartment (300) drags on the drawbar frame (140) that is connected on headstock (100), and the compartment is provided with hydraulic pressure self-unloading device (320).Improvement of the present utility model is: be provided with the back drive transmission device of being made up of transmission shaft and universal device (200) between the power take-off shaft (150) of headstock and rear drive sprocket (330,331).
With reference to Fig. 2 and Fig. 3, back drive transmission device (200) is made up of transmission shaft (211,212,213,214) and universal device (221,222,223,224), connects by universal device between two transmission shafts.
The structure of two rear drive sprockets (330,331) is close with the structure of back drive automobile, is not discussed at this.
Described transmission shaft (211,212,213,214) can be a single shaft, also can be that twin shaft is socketed to form, and the latter is beneficial to shockproof and flexible.
Can also be provided with change speed gear box (230) on the described back drive transmission device (200), change speed gear box (230) is fixed on the chassis Tuo Liang (310), the oil pump (321) of hydraulic pressure self-unloading device (320) is adjacent with change speed gear box (230), and by change speed gear box (230) by transmission shaft to oil pump (321) transmitting power.
In addition, can also be on transmission shaft (214), position, seat (340) next door is provided with hand brake device (350).
Said structure had both guaranteed f-w-d (not changing), and hydraulic pressure has increased the rear drive function again from unloading functions, has improved dynamic efficiency.And not high, the easy realization of manufacturing cost.These all are advantage of the present utility model places.
