Four-wheel steering axle assembly of farmland pesticide spraying car

Abstract

The invention discloses a four-wheel steering axle assembly of a farmland spraying vehicle, which includes a front axle and a rear axle; the front axle is a steering axle, including a front beam, a front wheel assembly, and a front wheel steering drive device; The two sides of the crossbeam include the front wheel, the front wheel steering lever, and the support assembly I. The support assembly I is set to make the front crossbeam higher than the front wheel; the rear axle includes the rear crossbeam and the rear wheel assembly; the rear wheel assembly is arranged on the two sides of the rear crossbeam side, including rear wheels, rear wheel steering levers, and support assembly II. Support assembly II is set so that the rear beam is higher than the rear wheels; further improvement is: the rear axle is a steering axle; the front axle and the rear axle are respectively equipped with steering position sensors System; one end of the steering tie rod is threadedly connected to the end of the piston rod protruding from the cylinder body of the power cylinder, and a flexible protective sleeve is provided to cover the joint. The invention significantly improves the height of the chassis of the plant protection spraying machine, and can quickly and reliably switch between the front wheel and the four-wheel steering according to different requirements.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an axle assembly of a plant protection spraying locomotive. Background technique [0002] The four-wheel steering axle assembly of the existing farmland spraying vehicle is arranged on the self-propelled vehicle body, including a front axle and a rear axle. The front axle includes a front beam and a front wheel. The front wheels are arranged on both sides of the front beam. Beam, rear wheel, the rear wheel is set on both sides of the rear beam, due to the limitation of the diameter of the front wheel and rear wheel, the chassis height of the plant protection sprayer is low, and the plant protection sprayer is easy to rub against the plant protection sprayer when walking in the farmland. The chassis of the pesticide machine will damage the plant protection sprayer. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a four...
