Abstract
The utility model discloses a travelling transmission mechanism of a tractor. A gearbox system is lowered and mounted, so that a driver's seat is moved downward, shaking during travelling is reduced, and a driver can comfortably drive; the gearbox system is lowered and mounted, so that the defect that the height of an output shaft of a branch power box is not consistent with that of a travelling transmission shaft is avoided, and the height of an output shaft of the branch power box is consistent with that of the travelling transmission shaft; and the travelling transmission mechanism is more standardized. The travelling transmission mechanism of the tractor is characterized in that the branch power box of the gearbox system is lowered, and the output shaft of the branch power box and the travelling transmission shaft are in the same horizontal surface, so that the driver's seat is moved downward, and the defect that the height of the output shaft of the branch power box is not consistent with that of the travelling transmission shaft is avoided; and travelling transmission parallel type shaft transmission is modified, so that the manufacturing cost is reduced. With the adoption of the improvement, defects of a conventional travelling transmission mechanism are avoided, so that the travelling transmission mechanism of the tractor is more reasonable, more reliable in performance and standardized.
Description
Technical field
The utility model relates to the walking transmission mechanism of a kind of field machine, particularly trac..Its system of mechanism drives the trac. walking, and the walking power of this train of mechanism transmits, the Power train of transmission translation function.
Background technology
Existing trac. walking transmission mechanism, normally because the branch headstock of change speed gear box can not hang down setting, and the transmission of employing transmission shaft inclined type, import power into to output shaft by a minute headstock, be folded to inclined type through universal-joint and pass to transmission shaft, again by transmission shaft transmission front axle, back axle ground-engaging wheel, thereby work the trac. walking effect that drives.Mode of work-doing: power imports into to output shaft from a minute headstock, is folded to through universal-joint, and inclined type passes to transmission shaft, again by transmission shaft transmission front axle, back axle ground-engaging wheel, makes the trac. walking.Shortcoming: (1) this trac. walking transmission mechanism, owing to adopt overhead high mode of putting of transmission system installation site, the operator's saddle of trac. is increased, the height of gravitational center height rocks during walking greatly, makes driving uncomfortable; (2) owing to adopt the walking transmission mechanism of inclined axle, increase manufacturing cost, maintenance increase expense.
Summary of the invention
The purpose of this utility model is to provide a kind of shortcoming that existing trac. walking transmission mechanism exists that solves.(1) avoids the too high defective in branch headstock installation site of transmission system, reduce the operator's saddle height, make driving more comfortable; (2) adopt the shaft drive of walking transmission run-in index, reduce manufacturing cost, convenient for maintaining makes the transmission normalisation.These two problems have significantly been improved the working condition of walking transmission mechanism.
The utility model is on the basis of existing trac. walking transmission mechanism, the branch headstock of transmission system is descended, divide the power delivery port of headstock to be level with the walking transmission shaft, operator's saddle is moved down, avoid the power delivery port and the inconsistent defective of walking transmission shaft height of branch headstock; Improve walking transmission mechanism, be run-in index shaft drive, reduce manufacturing cost, convenient for maintaining, specific as follows:
A kind of trac. walking transmission mechanism, it comprises, front axle, first transmission shaft, output shaft, branch headstock, change speed gear box, second transmission shaft, back axle; Walking transmission mechanism is installed in the vehicle frame below, it is characterized in that also comprising:
Drop-gear box divides headstock to descend, and divides output shaft and the transmission shaft of headstock to be level, and operator's saddle is moved down, and avoids the output shaft and the inconsistent defective of walking transmission shaft height of branch headstock;
Walking transmission mechanism is installed in the vehicle frame below, and transmission power is supplied with by trac., and the walking transmission is run-in index shaft drive, reduces manufacturing cost, convenient for maintaining.
Headstock descended in described minute, divided the output shaft of headstock and walking transmission shaft to be level.
The branch headstock output shaft of described walking transmission and transmission shaft are run-in index shaft drive, reduce manufacturing cost, convenient for maintaining.
The walking transmission mechanism of above structure is provided with the mechanism reasonable and more more reliable than existing walking transmission mechanism, reduces and makes and service expenditure.Above improvement makes walking transmission mechanism normalisation more.
Description of drawings
Fig. 1 is existing traditional trac. walking transmission mechanism scheme drawing.
Fig. 2 is the utility model trac. walking transmission mechanism scheme drawing.
Among the figure, Fig. 1: front axle 1, first transmission shaft 2, output shaft 3, branch headstock 4, change speed gear box 5, second transmission shaft 6, back axle 7.
Fig. 2: front axle 1, first transmission shaft 2, output shaft 3, branch headstock 4, change speed gear box 5, second transmission shaft 6, back axle 7.
The specific embodiment
By reference to the accompanying drawings, the utility model trac. walking transmission mechanism is described further:
Shown in Figure 1, be existing traditional trac. walking transmission mechanism scheme drawing.As we know from the figure, the trac. walking transmission mechanism of prior art adopts change speed gear box can not hang down the form of setting, make the transmission of transmission shaft inclined type mode, type of drive: power imports power into to output shaft 3 from minute headstock 4, be folded to inclined type through universal-joint and pass to first transmission shaft 2, second transmission shaft 6, again by first transmission shaft 2, second transmission shaft, 6 rotating drive front axles 1, back axle 7, thereby work the trac. walking effect that drives.
Weak point: (1) this trac. walking transmission mechanism, owing to adopt overhead high mode of putting of transmission system installation site height, the operator's saddle of trac. is increased, the height of gravitational center height makes driving uncomfortable; (2) owing to adopt the walking transmission mechanism of inclined axle, increase manufacturing cost, maintenance increase expense.
Shown in Figure 2: as to be the utility model trac. walking transmission mechanism scheme drawing.As we know from the figure, the utility model is on the basis of Fig. 1, decline is installed by change speed gear box 5 systems, the output shaft 3 and first transmission shaft 2 that divide headstock 4, second transmission shaft 6 is level, operator's saddle is moved down, avoid output shaft 3 and first transmission shaft 2 of branch headstock 4, the highly inconsistent defective of second transmission shaft 6, type of drive: power imports power into to output shaft 3 from minute headstock 4, pass to first transmission shaft 2 through the universal-joint horizontal, second transmission shaft 6, again by first transmission shaft 2, second transmission shaft, 6 rotating drive front axles 1, back axle 7, thus work the trac. walking effect that drives.
Advantage: change speed gear box 5 systems install and descend, and operator's saddle is moved down, and rock when reducing walking, make driving more comfortable; Because installing, change speed gear box 5 systems descend, avoid the output shaft 3 of branch headstock 4 and first transmission shaft 2, the highly inconsistent defective of second transmission shaft 6, the output shaft 3 that makes branch headstock 4 and first transmission shaft 2, second transmission shaft 6 are highly consistent, save manufacturing cost, be convenient to maintenance, realized the normalisation of trac. traveling gear.
Propulsion source among Fig. 2 all is by prior art constructions, is provided by the power of trac. itself.
