Abstract

The utility model discloses a special gear box for a high-torque energy-saving heavy-loading agricultural vehicle, which comprises a casing, a power input main shaft, auxiliary shafts and a power output transmission half shaft, wherein change gears at different levels are installed respectively on the power input main shaft and a first auxiliary shaft. Combined transfer gears with different diameters and installed on the first auxiliary shaft are in linkage with a transfer gear F installed on a third auxiliary shaft. The gears with small diameters of the combined transfer gears are transmitted through a second auxiliary shaft and the third auxiliary shaft, thereby enabling a transfer gear on the third auxiliary shaft to mesh with a big disc gear of a differential mechanism so as to achieve a low gear, or enabling the gears with big diameters of the combined transfer gears to mesh with the big disc gear of the differential mechanism for transmission so as to achieve a high gear. In terms of the transmission relation from the power input main shaft to the power output transmission half shaft, no speed-up process in which a big gear wheel drives a pinion exist in any of the gears, and therefore, capability loss caused by repeated conversion of rotation speed can be avoided.

Description

The special-purpose gearbox of the energy-saving heavy load agricultural vehicle of high moment of torsion
Technical field
The utility model relates to the agricultural vehicle gearbox, particularly relates to the special-purpose gearbox of the energy-saving heavy load agricultural vehicle of a kind of high moment of torsion.
Background technique
At agricultural vehicle single cylinder diesel tricycle, four-wheel wagon, and the retaining of three in the gearbox of hand tractor gear all exists gearwheel band small gear to satisfy the phenomenon that runs up with high retaining gear.That is to say that in transmission process, driving gear is less than driven gear during slow block, driving gear is greater than driven gear during top gear.This gearbox occurs earlier that the large gear turn the small gear when high gear, after the situation that small gear drives gearwheel appears again.The large gear turn the small gear causes moment of torsion to diminish, and power dwindles, and speed change can cause extra energy loss repeatedly, wastes energy.Include input main shaft and main shaft in the agricultural vehicle gearbox of heavy load at present; First, second is from axle and jackshaft; Adopt two pairs of gears of high bottom gear to be connected between input main shaft and the main shaft, a pair of reduction gear is a low speed when connecting, and is top gear during a pair of raising speed gear connection; Main shaft and first is respectively first, second and third retaining from being provided with three pairs of shift gears between the axle.Second is connected with the jackshaft gearing down from axle.Wherein the retaining of first on the main shaft is deceleration, and second retaining is that deceleration or speedup drive, and the 3rd retaining drives for speedup; The process of slowing down after the first speedup will appear in such transfer mode when height keeps off; Because speedup consumes moment and energy, speed is inevitable dynamic energy loss in transfer process repeatedly, and the gear shaft and the number of gears are too much during existing in addition top gear; Frictional force between gear increases; And the power that overcomes gear inertia in the gear transmission process, cause existing heavy load agricultural vehicle gearbox energy consumption when high speed excessive, be unfavorable for energy-conservation.
The model utility content
The utility model purpose is in order to address the above problem, to provide the energy-saving heavy load agricultural vehicle of a kind of high moment of torsion special-purpose gearbox.
The technological scheme of the utility model is: the special-purpose gearbox of the energy-saving heavy load agricultural vehicle of a kind of high moment of torsion; Comprise shell; Power input main shaft, from axle, power output jackshaft; Its medium power input main shaft and first, second, third is separately installed with corresponding driving gears at different levels from axle; Simultaneously the 3rd transfer gear installed from axle and the power output jackshaft differential mechanism deep bid gear coupling of installing meshes, first from axle be equipped with can transverse translation compound transfer gear, this compound transfer gear is composited by a larger-diameter gear A and the gear B than minor diameter side by side; And the transfer gear F that this compound transfer gear and the 3rd is installed from axle is linkage gear in the same way; When first from axle and second during from shaft drive, the major diameter transfer gear C coupling engagement of the gear B of compound gear and second from the axle; When the compound transfer gear of transverse translation makes first when axle and jackshaft are set up drive connection; The 3rd F translation of transfer gear and the differential mechanism deep bid gear installed from axle breaks off drive connection, thus the gear A of compound gear directly with jackshaft on differential mechanism deep bid gear coupling mesh.
All there is not the boosting velocity procedure of gearwheel driving pinion in power input main shaft to the drive connection between the power output jackshaft when any gear.
Highest gear gear on the power input main shaft meshes with first the minimum driven gear coupling from the axle, and on the main shaft diameter of highest gear gear be not more than first from the axle the diameter of minimum gear.
Said first from axle and second during from shaft drive; The major diameter transfer gear C coupling engagement of the gear B of compound gear and second from the axle; Second minor diameter transfer gear D and the 3rd major diameter transfer gear E coupling engagement from the axle from the axle, the 3rd minor diameter transfer gear F and power output jackshaft are installed from the axle differential mechanism deep bid gear coupling meshes.
The beneficial effect of the utility model:
1, the utility model utilization realizes speed regulating control from the compound transfer gear on the axle; It when the gear B of compound transfer gear plays transfer function bottom gear; It when the gear A of compound transfer gear plays transfer function top gear; And during top gear the 3rd from the axle the F translation of transfer gear and differential mechanism deep bid gear break off drive connection, first skips second and third from axle directly drives differential mechanism deep bid gear from axle.It is simple in structure, and control is easily made easily or transformed.Each gear distributed uniform, top gear rotating speed be not less than existing heavy load agricultural vehicle gearbox the most at a high speed.
2, in addition, in the whole transmittance process, all there is not the boosting velocity procedure of gearwheel driving pinion in the drive connection from power input main shaft to power the output jackshaft when any gear, can prevent that rotating speed from changing repeatedly and the ability loss that causes.And through the appropriate design gear ratio, the speed of top gear is not less than existing agricultural vehicle gearbox the most at a high speed, and the speed of minimum retaining is not higher than existing agricultural vehicle gearbox lowest speed.Drive the repetition transfer process of gearwheel reduction of speed after the raising speed that improved gearbox does not exist that the large gear turn the small gear again from small gear, so just can avoid comprehensive energy waste problem because of causing in the transfer process.
