Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.As it is shown in figure 1, final drive device after a kind of tractor combination type, including: basic module 1, transitioning component 2, high-clearance assembly 3, low wide assembly 4, adjustable component 5 and driving shaft 6.Planetary gear speed reducing mechanism is as basic module 1, the major parts such as the planet housing 1.1 in basic module 1, planet carrier 1.2 and planet carrier output shaft 1.3 are arranged on tractor rear axle and share lubricating oil with chassis, the positioning shaft sleeve 1.4 of planet housing 1.1 end face installation and sealing member realize location and seal, and the limit in high-clearance assembly 3 subtracts positioning shaft sleeve 3.1 and the sealing member realization location of housing 3.2 end face installation and seals；Be spirally connected the continuously planet housing 1.1 of basic module 1, the limit connecting housing 2.2 and high-clearance assembly 3 of transitioning component 2 subtracts housing 3.2, pass through spline inside planet carrier output shaft 1.3 and be bolted on planet carrier 1.2, after chassis power enters basic module 1, through spline housing 2.1 and driving shaft 6 incoming high-clearance assembly 3 and driving gear 3.3 keyed jointing is subtracted with limit by planet carrier output shaft 1.3, organize parallel gears speed changes through and lift high-clearance again, power is finally subtracted rear drive shaft 3.4 by limit and exports, it is achieved wide wheelspan high-clearance configures.
As shown in Figure 2, by high-clearance assembly 3 overall pulling down in Fig. 1, change the outfit as low wide assembly 4, i.e. be spirally connected the planet housing 1.1 of basic module 1 and the drive shaft shell 4.2 of low wide assembly 4, positioning shaft sleeve 4.1 and sealing member that drive shaft shell 4.2 end face is installed realize location and seal, and power is still inputted by planet carrier output shaft 1.3, is directly entered drive shaft 4.3 and exports after spline housing 2.1, realize wide wheelspan commonly gap configuration, wheelspan four can be realized by upset former and keep off adjustable.
As it is shown on figure 3, the transitioning component 2 in dismounting Fig. 1, then remove limit in high-clearance assembly 3 and subtract the positioning shaft sleeve 3.1 that housing 3.2 end face is installed, position and seal the positioning shaft sleeve 1.4 installed by planet housing 1.1 end face of basic module 1 and sealing member realizes；The planet housing 1.1 of basic module 1 that is directly spirally connected subtracts housing 3.2 with the limit of high-clearance assembly 3, while subtract positioning shaft sleeve 3.1 and the sealing member that housing 3.2 end face is installed, make planet carrier output shaft 1.3 be directly entered high-clearance assembly 3 and keyed jointing limit subtracts driving gear 3.3, subtracted rear drive shaft 3.4 by limit and export final power, it is achieved middle wide wheelspan high-clearance configuration.
As shown in Figure 4, by the transitioning component 2 in Fig. 1 and all removing with high-clearance assembly 3, change the outfit adjustable component 5, and flat key 5.1 connects wheel hub 5.3 and planet carrier output shaft 1.3, after bolt presses half anchor ear 5.2 and wheel hub 5.3, can realize ordinary wheel and configure away from commonly gap.Owing to bolt presses front hub can translate along flat key, make the wheelspan can be stepless adjustable in certain limit, then by upset former, it is achieved middle wide wheelspan configuration.
Outside planet carrier output shaft 1.3, order arranges spline keyway and flat key keyway, above four kinds of combinations can be connected with the spline of driving shaft 6 or drive shaft 4.3 by spline housing 2.1 respectively as power transmission shaft, also can subtract the spline of driving gear 3.3 with limit directly as driving shaft to be connected, can also be connected with adjustable component 5 flat key as drive shaft, make Same Part can realize difference in functionality under the configuration of various combination, avoid repeated disassembled and assembled, and intensity is also guaranteed.
In any of the above combination, wherein basic module 1 is the most constant, transitioning component 2 chooses to install for wide wheelspan configuration, high-clearance assembly 3 chooses to install for high-clearance configuration, low wide assembly 4 chooses to install for wide wheelspan commonly gap configuration, adjustable component 5 chooses to install for common and middle wide wheelspan commonly gap configuration, each component internal self-organizing system during assembling, six assemblies can form following pattern: basic module 1+ transitioning component 2+ driving shaft 6+ high-clearance assembly 3, the low wide assembly 4 of basic module 1+ transitioning component 2+, basic module 1+ high-clearance assembly 3 and basic module 1+ adjustable component 5 are respectively combined and realize four kinds of patterns.
Each positioning shaft sleeve big end end face all has countersunk screw holes, it is separately mounted to basic module 1, high-clearance assembly 3 and the housing end face of low wide assembly 4 by recessed electrical bolt, positioning shaft sleeve external diameter and inner radius are provided with sealing member, make three above assembly each independent, and have the unified seam size corresponding with positioning shaft sleeve at each casing joint surface, it is difficult to confusion when changing the outfit.
Any of the above measure can ensure that under various configurations combines, and the independent sealed requirement of each assembly makes need not drain the oil during switching, changes the outfit efficient and convenient simultaneously.
The present invention uses modularized design completely, there is function many, cover ground gap, wheelspan scope extensively, switch the features such as the most steerable, have extremely strong adaptation ability to needing the crop of highland gap length wheelspan work pattern and area with the large area cotton field of multirow work pattern etc..After using this device, because need not buy multiple stage tractor, user can be greatly decreased and purchase and maintenance cost, simultaneously the targeted design of high production rate single width multirow work pattern and commonly gap ordinary wheel freely switching away from pattern, improve its range of application, considerable economic benefit can be brought to enterprise.
