At present, the spatial triaxial formula gearbox gear that adopts on the crawler tractor of Sheng Chaning at home is few, is 4+2 retaining or 6+2 retaining, and this gear structure can not satisfy the various operating modes of crawler tractor now.Therefore, on the prior art basis,, develop a kind of compact structure by technological improvement, connection and reasonable arrangement, gear is many, and the crawler tractor that can satisfy the various operating modes of crawler tractor fully is necessary fully with short type triple axle gearbox.
The model utility content
The purpose of this utility model is to provide a kind of short type triple axle gearbox of the crawler tractor light, that reliability is high, axial dimension is short of handling.
The technical solution of the utility model is: a kind of crawler tractor comprises with short type triple axle gearbox: solid one 1, hollow gear shaft 2, jack shaft 3, second spool 4, often mesh driven gear 5, low gear driving gear 6, little engagement cover 7, the driving gear 8 that reverses gear, often mesh driving gear 9, three retaining driving gears 10, a retaining driving gear 11, three retainings and the driven gear 12 that reverses gear, big engagement cover 13, one retaining driven gear 14; It is characterized in that: solid one 1 is installed on the housing bearings at both ends, the hollow gear shaft 2 that is set with a retaining driving gear 11 is contained on solid one 1 by bearing housing, and jack shaft 3 and second 4 are installed in respectively on the housing bearings at both ends and are distributed in solid one 1 upper right side and bottom righthand side place by separately centre distance.
By spline housing normal engagement driving gear 9 is housed on solid one 1.
By spline housing normal engagement driven gear 5 is housed successively on the jack shaft 3, is set with low gear driving gear 6, little engagement cover 7 is housed, be set with the driving gear 8 that reverses gear by sliding bearing by spline housing by sliding bearing.
Three retainings are housed and reverse gear driven gear 12 by spline housing successively on second 4, big engagement cover 13 and one retaining driven gear 14.
The utility model can reach following beneficial effect after adopting technique scheme: by hollow shaft four axles are fused into triple axle, the gearbox gear is brought up to the 12+4 retaining by 4+2 retaining or 6+2 retaining, and gear-box axle is to size constancy, made full use of the confined space, connection and reasonable arrangement, compact structure, gear is many, can satisfy the various operating mode demands of existing crawler tractor fully.

Fig. 2 is the short type triple axle gearbox A-A structure cross-sectional schematic of the utility model crawler tractor.
Embodiment
As shown in Figures 1 and 2, this crawler tractor comprises with short type triple axle gearbox: solid one 1, hollow gear shaft 2, jack shaft 3, second spool 4, often mesh driven gear 5, low gear driving gear 6, little engagement cover 7, the driving gear 8 that reverses gear, often mesh driving gear 9, three retaining driving gears 10, a retaining driving gear 11, three retainings and the driven gear 12 that reverses gear, big engagement cover 13, one retaining driven gear 14.Solid one 1 is installed on the housing bearings at both ends, the hollow gear shaft 2 that is set with a retaining driving gear 11 is contained on solid one 1 by bearing housing, jack shaft 3 and second 4 are installed in respectively on the housing bearings at both ends and are distributed in solid one 1 upper right side and bottom righthand side place by separately centre distance, become spatial triangle to distribute.By spline housing normal engagement driving gear 9 is housed on solid one 1.By spline housing normal engagement driven gear 5 is housed successively on the jack shaft 3, is set with low gear driving gear 6, little engagement cover 7 is housed, be set with the driving gear 8 that reverses gear by sliding bearing by spline housing by sliding bearing.Three retainings are housed and reverse gear driven gear 12 by spline housing successively on second 4, big engagement cover 13 and one retaining driven gear 14, other shift gear mounting structure is similarly.
During work, power drives normal engagement driving gear 9 with the rotating speed rotation from solid one 1 input, by normal engagement driven gear 5 power is reached jack shaft 3, and other gear does not rotate before not putting into gear.After hanging up low gear driving gear 6 by little engagement cover 7, power reaches hollow gear shaft 2 by low gear driving gear 6, this moment, the retaining of one on the hollow gear shaft 2 driving gear 11 was with the rotating speed rotation identical with hollow gear shaft 2, a retaining driven gear 14 that is meshed with it is around second 4 rotation, do not rotate second 4 of at this moment, after hanging up a retaining driven gear 14 by big engagement cover 13, second 4 with the rotating speed output identical with a retaining driven gear 14, at this moment, the tractor speed of a motor vehicle is a retaining.In like manner, by hanging up different gears, tractor can be realized 12 forward gear speed.When reversing gear, after hanging up the driving gear 8 that reverses gear by little engagement cover 7, power directly reaches three retainings and reverses gear driven gear 12 by the driving gear 8 that reverses gear, this moments three, retaining dallied around second 4 with the driven gear 12 that reverses gear, and second 4 do not rotated, power reaches the three retaining driving gears 10 that are meshed with it by three retainings and the driven gear 12 that reverses gear again, retaining driving gear 11 on this moment hollow gear shaft 2 and its rotates with the rotating speed identical with three retaining driving gears 10, after hanging up a retaining driven gear 14 by big engagement cover 13, second 4 same rotational speed outputs with a retaining driven gear 14, at this moment, the tractor speed of a motor vehicle is for falling a retaining.In like manner, hang up different gears by big engagement cover 13, then tractor can be realized 4 reverse speeds.
The utility model is fused into triple axle by hollow shaft with four axles, has made full use of the confined space, connection and reasonable arrangement, and compact structure, gear is many, can satisfy the various operating mode demands of existing crawler tractor fully.
