Problems solved by technology

[0003] Most of the current self-leveling mechanisms on the chassis of small agricultural vehicles use hydraulic systems. When the chassis of small agricultural vehicles is tilted, the hydraulic push rod pushes the chassis to rotate around the fulcrum to keep the chassis level, but it is bulky and heavy

Abstract

The invention discloses a variable-diameter wheel and an agricultural vehicle chassis. The wheel comprises a wheel disc, a wheel shaft, a stepping motor, a gear assembly, a plurality of sliding mechanisms, a installation disc and a plurality of arc-shaped tires. The stepping motor drives the wheel disc to rotate through the gear assembly. The plurality of sliding mechanisms are fixed on the installation disc along the radial line of the wheel shaft; a first through hole is formed in the center of the wheel disc; the wheel shaft penetrates through the first through hole and then is fixedly connected with the installation disc; the wheel disc is provided with a plurality of strip-shaped grooves, the strip-shaped grooves, the sliding mechanisms and the arc-shaped tires are in one-to-one correspondence, a certain included angle is formed between each strip-shaped groove and the corresponding sliding mechanism, each strip-shaped groove is in sliding connection with the first end of the corresponding sliding mechanism, and the second end of each sliding mechanism is fixedly connected with the corresponding arc-shaped tire. The diameter of the wheels can be adjusted, so that the chassis of the vehicle is in a balanced state, and the vehicle can better adapt to inclined terrains such as hills and mountains.

Description

technical field [0001] The invention relates to a wheel, in particular to a variable-diameter wheel and an agricultural vehicle chassis, belonging to the technical field of agricultural machinery. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. [0003] Most of the automatic leveling mechanisms on the chassis of small agricultural vehicles currently use hydraulic systems. When the chassis of small agricultural vehicles is tilted, the hy...
