Problems solved by technology

The former has good maneuverability, but because of its high center of gravity and short contact length, it is not conducive to climbing obstacles such as large slopes or stairs; while the latter has a large contact area and longer contact length between the track and the ground, coupled with a low chassis and a low center of gravity. Easy to climb stairs or drive on complex road surfaces, but its flexibility and mobility are limited
In addition, the supporting wheel train frame of these two crawler structures is fixed with the locomotive as a whole, which also seriously affects the shock absorption effect.

Embodiment Construction

[0016] As shown in the figure, in the figure, the supporting link a6, the supporting link b9, and the supporting wheel train frame 4 are connected with the fixed shaft I15 and shaft II16 on the base 18 to form a parallel four-bar mechanism. The supporting wheel train frame 4 and the base body 18 can always be kept parallel. The cylinder body and the piston of the cylinder 8 are respectively hinged with the base body 18 and the supporting wheel train frame 4, and are used to drive the deformation of the mechanism. The ball guide rail 2 is fixedly connected with the base body 18, the movable frame 1 is installed on the ball guide rail 2, and the movable frame 1 can be stretched back and forth on the ball guide rail. The supporting link a6 is connected to the movable frame 1 through the damper 5, and drives the movable frame 1 to expand and contract while the parallelogram mechanism is deformed. With the fine adjustment of the damper, the constant tension of the crawler belt 17 c...

Abstract

The invention discloses a diction caterpillar band system. It includes base body, caterpillar band, drive wheel, and driven wheel. Its features are that the system also includes a parallelogram linkage used the base body as the frame, a rolling stretching structure connected to the base body, and supporting wheel train structure with linear array. The parallelogram linkage is respectively hinge joint to the connecting rod of the base body and the parallelogram linkage by the cylinder (oil cylinder) and piston. The rolling stretching structure is connected the parallelogram linkage by supporting connecting rod and damper. The supporting wheel train structure with linear array is connected to the supporting wheel frame of the parallelogram linkage. The system is drove the distortion, adjusted the center of gravity, kept the tensile force of the caterpillar band, and improved its shock absorption effect by the cylinder and the parallelogram linkage. This make the moving mechanism installed the system not only possess better mobility, maneuverability, and shinnied obstacle ability, but also possess better stability and dynamic performance, moreover the superior shock absorption ability.

Description

technical field [0001] The invention relates to a track system suitable for cross-country, stair climbing and military use. Background technique [0002] At present, the track systems used by engineering locomotives, military locomotives and robots can be roughly divided into a tank-like inverted trapezoidal structure and a bulldozer-like flat elongated structure from the structural appearance. The former has good maneuverability, but because of its high center of gravity and short contact length, it is not conducive to climbing obstacles such as large slopes or stairs; while the latter has a large contact area and longer contact length between the track and the ground, coupled with a low chassis and a low center of gravity. It is easy to climb stairs or drive on complex road surfaces, but its flexibility and mobility are limited. In addition, the supporting wheel train frame of these two crawler structures is fixed as a whole with the locomotive, which also seriously affec...
