In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: four wheel drive hand-variable transport plane, comprise head that constitutes by diesel engine, power-transfer clutch, main-gear box, direction machine assembly and preceding wheel assembly and the trailer that constitutes by trailer and rear wheel assembly, be connected with axis of traction by articulated body between head and the trailer, it is characterized in that in main-gear box, drawing a power take-off shaft, power take-off shaft realizes that with the rear driving axle in the rear wheel assembly power connects by auxiliary gear box assembly and drive disk assembly, realizes that front and rear wheel drives simultaneously.
Owing to adopted design plan as above, the utility model is by the direct outputting power of main-gear box, rear driving axle in drive disk assembly and rear wheel assembly combines as a whole, formed a complete driving system, realized that front-wheel (head), trailing wheel (trailer) drive function simultaneously, it is compared with existing hand-variable transport plane, has following advantage:
1, keeping having increased the rear drive function on the intrinsic advantage of the former type basis, it is poor thoroughly to have solved former type grade climbing performance, the front driving wheel problem of skidding under the load.
2, obviously improve the carload quality, reduce the damage of tire premature wear and road pavement.
3, adapt to the mountain area especially, hillside fields and hollow mud road surface and forest zone do not have the use of road environment, have increased the range of use and the market share of former type.
4, can drag on the type directly equippedly at the existing dish of user, make the trac. function upgrading, compact integral structure, recondition expense is low.
5, the complete machine power utilization obviously improves.
6, the takeoff output function that keeps former main-gear box can be used as hydraulic efficiency gear and other device power uses.Through Jiangxi, forest zone, mountain area tests such as Guizhou, Hunan, safety, reliability, driver behaviors etc. are functional.
Description of drawings
Fig. 1 is the structure diagram of existing hand-variable transport plane;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the utility model rear drive takeoff output sketch;
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Among Fig. 1,11-diesel engine, 12-power-transfer clutch, wheel assembly before 13-main-gear box, the 14-direction machine assembly, 15-, 1-head, 21-trailer, 22-rear wheel assembly, 2-trailer, 23-articulated body, 24-axis of traction.
Four wheel drive hand-variable transport plane as shown in Figures 2 and 3, comprise head 1 that constitutes by diesel engine 11, power-transfer clutch 12, main-gear box 13, direction machine assembly 14 and preceding wheel assembly 15 and the trailer 2 that constitutes by trailer 21 and rear wheel assembly 22, be connected with axis of traction 24 by articulated body 23 between head 1 and the trailer 2, in main-gear box 13, draw a power take-off shaft, this power take-off shaft can be to reset a power take-off shaft, also can be to adopt main-gear box 13 original primary shafies 132 or power take-off shaft 131 or active umbrella gear shaft 133.But preferably utilize active umbrella gear shaft 133 to carry out takeoff output.Can keep the function of original power take-off shaft 131 like this, make more compact structure, be convenient to Transmission Ratio Control.Active umbrella gear shaft 133 realizes that with the rear driving axle 221 in the rear wheel assembly 22 power connects by auxiliary gear box assembly 31 and drive disk assembly, realizes that front and rear wheel drives simultaneously.
Drive disk assembly comprises universal-joint I32, universal-joint II33, transmission shaft I34, transmission shaft II35, transmission shaft III36, coupler 37; Active umbrella gear shaft 133 is the rear drive power input shaft of auxiliary gear box assembly 31, connect by universal-joint I32 between the rear drive power take-off shaft 311 of auxiliary gear box assembly 31 and the transmission shaft I34, connect by coupler 37 between transmission shaft I34 and the transmission shaft II35, connect by universal-joint II33 between transmission shaft II35 and the transmission shaft III36, connect between the rear driving axle 221 in transmission shaft III36 and the rear wheel assembly 22.
