Abstract

The invention discloses an agricultural electric chassis provided with double-torsion-bar and parallel-four-connecting-rod type independent suspensions. A seat operation chamber, a control system cabinet, a storage battery pack and a hydraulic power system assembly are mounted on the upper side of a vehicle frame; four lifting hydraulic cylinders and four double-torsion-bar suspensions are mounted on the lower side of the vehicle frame, the left-front double-torsion-bar suspension is connected with the vehicle frame through the first lifting hydraulic cylinder, the left-rear double-torsion-bar suspension is connected with the vehicle frame through the second lifting hydraulic cylinder, the right-rear double-torsion-bar suspension is connected with the vehicle frame through the third lifting hydraulic cylinder, and the right-front double-torsion-bar suspension is connected with the vehicle frame through the fourth lifting hydraulic cylinder; one end of each of double torsion bars of each of the left-front double-torsion-bar suspension, the left-rear double-torsion-bar suspension, the right-front double-torsion-bar suspension and the right-rear double-torsion-bar suspension is fixed on the vehicle frame, and the other end is connected with the corresponding double-torsion-bar suspension through a spline connection sleeve. The universal chassis can realize lifting adjustment, variation of the left-right wheel track and skid steering, integrates multiple functions and has universality and flexibility.

Description

technical field [0001] The invention relates to a facility agricultural machinery chassis, in particular to an agricultural electric chassis with a double-twisted parallel four-bar independent suspension suspension. Background technique [0002] By the mid-1990s, the area of ​​China's protected vegetables had been ranked first in the world, accounting for about 90% of the world's total area. The development of China's protected agriculture has taken shape, but the overall production level is still in the initial stage of development. [0003] Greenhouse operation power machinery and supporting equipment are indispensable and important equipment for modern facility agriculture, but the supporting level of operation machinery is not high. At present, many operations such as arable land, leveling land, sowing, thinning, intertillage and weeding require different agricultural machinery. The existing agricultural machinery chassis lacks versatility, so the investment cost for fa...
