Abstract

The invention discloses a tractor identical-track steering mechanism, which comprises a steering driving device, a front steering trapezoid shape, a middle reversing linkage rod system and a back steering trapezoid shape. The invention also discloses a steering method of the tractor identical-track steering mechanism. The tractor identical-track steering mechanism and the steering method have the advantages that the structure is simple, the work is reliable, the manufacture cost is lower, and the tractor identical-track steering mechanism and the steering method are used for low-speed running tractors.

Description

technical field [0001] The invention relates to a tractor running at a low speed in farmland, in particular to a tractor steering mechanism in the same track and a steering method thereof. Background technique [0002] When ordinary wheeled tractors turn in the field, the rear wheels cannot follow the track of the front wheels, and the tires will crush the crops and compact the soil more seriously. Because the compaction of the soil can cause the reduction of crop production and the additional consumption of locomotive power, it also aggravates the wear and tear of agricultural implements. With the increase of mechanical operation speed, this consequence will be more serious. [0003] In farmland operations, the negative consequences of the locomotive's compaction of the soil have long attracted worldwide attention, and all efforts are being made to reduce this phenomenon. Tractors that can steer the front and rear wheels in the same track can minimize the crushing of soil ...
