Abstract
The utility model discloses a transmission integrated type font-rear drive minitype tractor, comprising a front bridge, a rear bridge, an air-cooled diesel engine and a transmission mechanism which transmits the power of the air-cooled diesel engine to the front bridge and the rear bridge, and the transmission mechanism is a comprehensive transmission case and comprises a power input shaft which is connected with an output shaft of the diesel engine, a front bridge output shaft which is connected with the front bridge, a rear bridge output shaft which is connected with the rear bridge, a forward-reverse operating rod and a front bridge output shaft disengagement operating rod. The transmission mechanism is the comprehensive transmission case which integrates a main gear box, a secondary gear box and a transfer case of the traditional tractor; a transmission system structure is simplified, the spatial distribution is optimized, and the manufacturing and using cost of the transmission mechanism is reduced; and the diesel engine type can be changed by adopting the technology of the transmission integrated type font-rear drive minitype tractor, the existing water-cooled diesel engine can be replaced by the air-cooled diesel engine, the connecting structure of the diesel engine and the comprehensive transmission case is simplified, and the air-cooled diesel engine is lighter in weight and is cheaper in price.
Description
(1) technical field:
The utility model relates to trac., specifically is to drive mini tractor before and after a kind of transmission integrated form.
(2) background technology:
Existing mini tractor has before driving, rear drive and front and back to drive three kinds; The transmission device that is provided with between the propons of the mini tractor that front and back drive and the back axle has main-gear box, auxiliary gearbox and auxiliary gear box; Main-gear box and auxiliary gearbox are located in the operator's compartment; The input shaft of auxiliary gearbox connects the diesel engine output shaft through power-transfer clutch, and the output shaft of auxiliary gearbox connects the input shaft of main-gear box, and auxiliary gear box is located on the frame of under-cab; The output shaft of main-gear box connects the input shaft of auxiliary gear box, and two output shafts of auxiliary gear box are connected with back axle with propons to forward and backward respectively.
Because the volume of mini tractor fuselage is less, main-gear box and auxiliary gearbox are located in the narrow and small operator's compartment, not only occupy the driving interior space, hinder the operation of chaufeur especially; Secondly higher, the reduction that is unfavorable for the mini tractor cost of the price of main-gear box, auxiliary gearbox and auxiliary gear box; The total weight of main-gear box, auxiliary gearbox and auxiliary gear box is also bigger in addition, can't make the mini tractor weight reducing, also is the major reason of mini tractor watt loss.
(3) utility model content:
The purpose of the utility model is driven mini tractor before and after having provided a kind of transmission device compact conformation and lightweight transmission integrated form.
Can realize driving mini tractor before and after the transmission integrated form of above-mentioned purpose; Comprise forward and backward bridge and diesel engine and with the transmission device of the transmission of power of diesel engine to forward and backward bridge; Different is said transmission device is the comprehensive transmission gearbox of one for main-gear box, auxiliary gearbox and the auxiliary gear box function of the traditional trac. of collection, and the propons output shaft that said comprehensive transmission gearbox comprises the power input shaft that connects the diesel engine output shaft, connect forward and backward bridge respectively is with the back axle output shaft and advance, reverse gear lever separates joystick with the propons output shaft.
Said power input shaft and propons output shaft are located at the upper and lower position of comprehensive transmission gearbox front side (towards head one side) respectively, and said back axle output shaft is located at the following position of comprehensive transmission gearbox rear side (head one side dorsad).
Said comprehensive transmission gearbox is installed on the fuselage chassis of operator's compartment bottom, and the top of comprehensive transmission gearbox is located in the operator's compartment, advances, reverse gear lever separates the place ahead, right side that joystick is positioned at operator seat with the propons output shaft.
Because the power input shaft of comprehensive transmission gearbox can adopt the air cooling type diesel engine as power towards the place ahead, the output shaft of air cooling type diesel engine connects the power input shaft of comprehensive transmission gearbox backward through power-transfer clutch.
Said comprehensive transmission gearbox be designed with by advance, three forward gears of reverse gear lever control and one reverses gear.
The advantage of the utility model:
The driving system of 1, driving mini tractor before and after the utility model transmission integrated form is the comprehensive transmission gearbox of one for main-gear box, auxiliary gearbox and the auxiliary gear box function of the traditional trac. of collection; Simplified the transmission device structure; Optimize space layout, reduced the manufacturing cost of transmission device.
2, adopt the utility model technology; Can also change diesel type; The water cooled diesel engine that is about to former usefulness changes the air cooling type diesel engine into, simplified the connection structure of diesel engine with comprehensive transmission gearbox, and air cooling type diesel engine weight is lighter; Price is more cheap, thereby has reduced the total weight and the integrated cost of trac..
(4) description of drawings:
