Abstract

The utility model discloses an overall structure device of a high power articulated wheeled tractor, which mainly comprises a front and a rear frames, a front and a rear drive axles, an engine, a transmission case, a transfer case, a power output speed reducing case, etc., wherein, the design kernel of the utility model is a main frame. The engine, the transmission case, and the transfer case are integrated to form a module, the front drive axle, the rear drive axle, and the power output speed reducing case respectively form an independent module, and the large modules are connected by a plurality of drive shafts. The design requirements of a tractor, such as, high power, good power performance, high work efficiency, flexible motion, etc. can be nicely realized by the connecting arrangement between the large modules and the frame, the structural type of the front and the rear frames and a rolling frame, and the adoption of mature members in other technical fields.

Description

High-power radial type wheel-tire tractor complete machine structure device

The utility model belongs to agricultural mechanical field, relates to a kind of complete machine structure device that is applicable to high-power radial type wheel-tire tractor.

Domestic existing radial type wheel-tire tractor power is little, and its complete machine structure and arrangement exist power to extend upward difficulty, structure than problems such as complexity.

The purpose of this utility model is to provide a kind of compact conformation, uses high-power radial type wheel-tire tractor complete machine structure device reliable, that satisfy the complete machine operating needs.

The utility model adopts following technical scheme to realize above-mentioned purpose: the core of high-power radial type wheel-tire tractor complete machine structure device is a main car frame, driving engine and change speed gear box, auxiliary gear box fuse and form a module, front driving axle, rear driving axle, each self-forming of takeoff output drop-gear box be module independently, adopt a plurality of power delivered couplings to link to each other between these several big modules, other parts such as operator's compartment, fuel tank, equipment or the like are also independent to link to each other with main car frame.The forward and backward drive axle of trac. adopts the ripe construction machinery and equipment drive axle that the free wheel type diff is housed in this device, and is rigidly connected with the front and back vehicle frame respectively; Driving engine, change speed gear box and auxiliary gear box fuse and realize that by six cushion blockings and front vehicle frame elasticity is connected; Two cushion blockings of driving engine and main car frame are 45, and all the other four cushion blockings then link to each other with vehicle frame is vertical; The left and right sides crossbeam of front and back vehicle frame adopts the bending of 10～12mm plate iron to form, and bending to the channel-section steel height is 230～250mm, and last lower edge width is 80～90mm; This trac. complete machine is made up of for two sections front and back, and the front and back vehicle frame links to each other by hinge pin, and realizes the radial type fluid-link steering by two oil cylinders.When general layout, hinge-point is arranged in point among the antero posterior axis line of centres, be the relative teeter between the vehicle frame before and after realizing, adopted and rolled rack and panel construction, rolling frame is arranged on the vehicle frame of back, rolling shelf structure is drum-type, and its revolution axial line is concentric with the back axle input shaft, and diameter of cylinder is 290～310mm; Hinge pin adopts double-pin, and the upper-lower position spacing reaches 720～740mm, to increase the torsion stiffness of frame itself; Back axle input shaft and power take-off drive shaft are between hinge pin up and down, and power take-off drive shaft is positioned at cylinder axis of revolution side in the heart, backward power is reached the takeoff output drop-gear box by a scalable transmission shaft.

Fig. 1 is the utility model structure diagram:

Compositions such as high-power radial type wheel-tire tractor complete machine structure device as shown in Figure 1 comprises front vehicle frame 1, driving engine 2, front driving axle 3, Parking Brake 4, change speed gear box 5, auxiliary gear box 6, rolls frame 7, rear driving axle 8, takeoff output drop-gear box 9, back vehicle frame 10.

Trac. is when normal operation, driving engine 2 power reach front driving axle 3 via a transmission shaft forward by power-transfer clutch, change speed gear box 5, front driving axle 3 is normal the driving, the power of rear driving axle 8 then can disconnect by auxiliary gear box 6, when auxiliary gear box 6 in conjunction with the time, driving engine 2 power by change speed gear box 5, auxiliary gear box 6 toward after transmission shaft reaches rear driving axle 8 through rolling frame 7.Because driving engine 2 is connected for elasticity with front vehicle frame 1 with change speed gear box 5, front driving axle 3 and front vehicle frame 1 are for being rigidly connected, therefore add and between change speed gear box 5 and the front driving axle 3 Parking Brake 4 is housed and makes distance too short, when structure design, make from change speed gear box and draw power and the axle sleeve that links to each other with transmission shaft can endwisely slip at axle.
