Rubber caterpillar band tensioning mechanism for all-terrain vehicle

Abstract

The invention discloses a rubber caterpillar band tensioning mechanism for an all-terrain vehicle. The rubber caterpillar band tensioning mechanism comprises damping arms (1), a damping rubber assembly (2), damping lengthening arms (3), a front tensioning transverse board (4), symmetrically-assembled adjusting rods (5), a tensional axle (6), a rear tensioning transverse board (7), symmetrically-assembled tensioning wheels (8), adjusting bolts (9) at the two ends of the adjusting rods (5) and locating devices (10) arranged on the tensional axle (6) and used for locking the axle. The rubber caterpillar band tensioning mechanism has the beneficial effects that the work principle is simple and clear, operation is quick in a labor-saving manner, the structure is simple, and reliability is good, the adjusting work stroke of the mechanism is large, the extreme stroke required by caterpillar band adjustment, disassembly and assembly can be obtained, and the tensioning mechanism is suitable for caterpillar band adjustment, disassembly and assembly of the all-terrain vehicle.

Description

technical field [0001] The invention relates to a crawler belt tensioning mechanism, in particular to a rubber crawler belt tensioning mechanism of an all-terrain vehicle. Background technique [0002] At present, the monorail chain combined metal track is widely used in tracked construction vehicles because of its low manufacturing cost, and its tensioning mechanism is a slider structure composed of a tensioning cylinder and a buffer spring. However, the metal crawler is heavy and does not meet the lightweight requirements necessary for the all-terrain passability of the all-terrain vehicle, and the crawler-type all-terrain vehicle is a kind of harsh environment that can not only be used in mountains, forests, swamps, sandy land and other roads with low requirements. It can also be used in environments with high road requirements such as urban flood disasters and engineering emergency rescue. In order to reduce the weight of the vehicle without damaging roads, especially u...

Problems solved by technology

[0005] In order to overcome the problems in the prior art that the structure is relatively complicated, the track is inconvenient to disassemble due to the limited working stroke of the adjustment, and the mechanism cannot effectively buffer the vibration from the frame and the track due to the lack of a shock absorbing device in the mechanism itself, this paper The invention provides a rubber track tensioning mechanism for an all-terrain vehicle, which is characterized in that it includes a shock absorbing arm, a shock absorbing rubber block assembly, a shock absorbing extension arm, a tensioning front cross plate, a symmetrically assembled adjusting rod, and a tensioning wheel shaft , tensioned rear cross plate, symmetrically assembled tensioning wheel, adjusting bolts at both ends of the adjusting rod and a locking device on the tensioning wheel shaft for locking the wheel shaft
