Abstract
The utility model relates to a seven gear-combined rear axle for a farm vehicle. Compared with current common five gear-combined rear axle of a farm vehicle, the utility model is characterized in that a sliding gear is added to a third shaft and a fixing gear is added to a forth shaft, which increases the variation ratio of the high speed gears and the low speed gears. In order to facilitate outfitting the farm vehicle with various farm implements, a connecting bracket for the hanging pieces are arranged at the external backside of the gear-box. The rear axle assembly can be in a semi-floating structure or in a full-floating structure; the clutch is a common dry clutch with four grooves and two plates. The utility model is simple in structure and is provided with high speed gears and the low speed gears, meeting the demands of different usage of the farm vehicle, thus the utility model has bright market prospect.
Description
The utility model relates to a kind of structure of farm vehicle connected rear axle change speed gear box.
At present, agriculture truck is distributed in road conditions religions such as mountain area, hills more and is complicated region, in use need frequent conversion gear, and the user loads more, the user who also has is sought after a kind of energy and realizes multiduty back axle, can be used for engineer operation, can be used for irrigation and water conservancy operation etc. again, this just needs the dependable performance of farm vehicle, and hill climbing ability is strong.But present farm vehicle is owing to be subjected to the restriction of gearbox designs, and it mostly is five grades of speed changes, and gear is few, can not satisfy the demand.Though the change speed gear box gear that has is many, complex structure, the cost height is difficult to apply.
The purpose of this utility model provide a kind of simple in structure, have height gear speed change, and the maneuverable connected rear axle of gear.
For achieving the above object, the utlity model has the I axle that places in the gearbox body, the II axle, the III axle, IV axle and differential assembly, its constructional feature is: on its power input shaft I axle driving gear is housed, on the II axle driven gear is housed, fixed gear wheel and cliding gear, the shift cliding gear is housed on the III axle, cliding gear and fixed gear wheel, two fixed gear wheels and extreme gear are housed on the IV axle, driven gear engagement on driving gear and the II axle, shift cliding gear on the III axle can mesh with driven gear and the fixed gear wheel on the II axle, cliding gear on the III axle can with any engagement in two fixed gear wheels on the IV axle, cliding gear on the II axle can mesh with the fixed gear wheel on the III axle, extreme gear and differential assembly engagement.
Be equipped with various agricultural machinery and implement for ease of farm vehicle, also be provided with hanging device at the outside rear side of gearbox body and connect support.
After adopting said structure, the utility model just increases a cliding gear on the III axle in gearbox body, increase a solid moving gear on the IV axle in the gearbox body, two D Drives promptly on the basis of original gear, have been increased, increased the converter speed ratio of height gear, satisfied the demand of the frequent conversion gear of needs in use, simple in structure, outside rear side at gearbox body is provided with hanging device connection support simultaneously, satisfy the multiduty requirement of farm vehicle, had vast market prospect.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Accompanying drawing is a cross-sectional view of the present utility model.
Seven grades of connected rear axles of farm vehicle shown in the drawings, being linked and packed by change speed gear box and back axle forms, and is provided with I axle 13, II axle 14, III axle 15, IV axle 16 in gearbox body 12; I axle 13 is a power input shaft, and fixed gear wheel 3 and cliding gear 7 also are equipped with in driving gear 1 on it and 2 engagements of the fixed gear wheel on the II axle 14 on II axle 14; Cliding gear 4, shift cliding gear 5 and fixed gear wheel 8 are housed on III axle 15; Fixed gear wheel 6,9 is housed on IV axle 16, and extreme gear 10 cooperates the realization takeoff output by extreme gear 10 with differential assembly 11.When by cliding gear 4 on the III axle 15 and 6 engagements of the fixed gear wheel on the IV axle 16, when realizing high-grade variable-speed dynamic output and fixed gear wheel 9 engagements, realize low-grade variable-speed dynamic output.When by 3 engagements of the fixed gear wheel on shift cliding gear on the III axle 15 5 and the II axle 14, realize the I shelves transmission of power of height gear, when cliding gear 7 on the II axle 14 and 8 engagements of the fixed gear wheel on the III axle 15, realize the II shelves transmission of power of height gear, shift cliding gear 5 on the III axle 15 again with II axle 14 on fixed gear wheel 2 engagement the time, realize the III shelves transmission of power of height gear.Reverse gear then is to realize by 9 engagements of the fixed gear wheel on cliding gear on the II axle 14 7 and the IV axle 16.Thereby realize the speed changing structure of six D Drives and a reverse gear.Back axle assembly can adopt the semi-floating structure, divides two kinds of brakings of mechanical type and hydraulic pressure pattern, also can adopt the full-floating structure, divides two kinds of brakings of mechanical type and hydraulic pressure pattern, and power-transfer clutch adopts general-duty four groove dual-sheet dry type structure.Simultaneously for ease of being equipped with various agricultural machinery and implement, also being provided with hanging device at the outside rear side of gearbox body 12 and connecting support 17.
