Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
As shown in fig. 1 to 4, the terrain-imitating wheeled tractor of the present embodiment includes a front frame 1 and a rear frame 2 hinged to each other, a front axle 3 and a power device 4 are installed on the front frame 1, a rear axle 5 is installed on the rear frame 2, traveling wheels 6 are installed at both ends of the front axle 3 and the rear axle 5, a steering drive device for driving the front frame 1 and the rear frame 2 to rotate relatively is installed between the front frame 1 and the rear frame 2, and the front axle 3 is hinged to the front frame 1 and can swing around a hinge axis to move up and down the two traveling wheels 6 on the front axle 3. This imitative wheeled tractor's preceding frame 1 and back frame 2 are articulated each other, and 3 articulated installations on preceding frame 1 of front axle, and front axle 3 can be swung so that two walking wheels 6 up-and-down motion on the front axle 3 around articulated axis, and front axle 3 can carry out the swing of multi freedom for imitative wheeled tractor has imitative topography function, the uneven road conditions in adaptation ground that can be better, improves the stationarity of imitative wheeled tractor and the trafficability characteristic in uneven road conditions. The terrain-imitating wheel type tractor has the advantages of simple and compact structure, easiness in manufacturing and assembling and low cost, and is particularly suitable for complex terrain operation in hilly areas and the like.
In this embodiment, the front frame 1 is provided with the elastic buffer assembly for blocking the swing of the front axle 3, and the vibration from the road surface can be greatly reduced by utilizing the elastic buffer effect of the elastic buffer assembly, so that the walking stability of the terrain-imitating wheeled tractor is improved.
In this embodiment, the elastic buffer subassembly includes two elastic buffer 8, the both ends of each elastic buffer 8 correspond respectively and are articulated with front axle 3 and front frame 1, two elastic buffer 8 set up for front frame 1 and 3 articulated axes of front axle symmetry, when front axle 3 swung to arbitrary side for front frame 1, all there is an elastic buffer 8 compressed and played the elastic buffer effect, consequently elastic buffer 8 only need adopt the buffer of one-way buffering can, but also can reduce cost, and buffering effect is better, and when front axle 3 swung to the same angle to both sides respectively for front frame 1, the total of the elastic obstruction force of two elastic buffer 8 is unchangeable, do benefit to further improvement buffering effect.
