Adaptive Leveling Chassis

Abstract

The invention belongs to the technical field of agricultural machinery, and discloses a self-adaptive leveling chassis. The self-adaptive leveling chassis includes four or six self-adaptive leveling suspension frames which are mounted on the same car frame and arranged symmetrically abouta longitudinal plane of the center of the car frame based on given wheelbase and wheelspan. Each self-adaptive leveling suspension frame is composed of a front cantilever, a rear cantilever, a front connecting rod, a rear connecting rod, a pressure spring, wheels and a support frame, wherein one end of the front cantilever and one end of the rear cantilever are connected and rotate around an A point on the support frame, and the other end of the front cantilever and the other end of the rear cantilever are rotatably connected with the wheels respectively; one end of the front connecting rod is hinged to one end of the rear connecting rod, the other end of the front connecting rod is rotatably connected with the front cantilever, and the other end of the rear connecting rod is rotatably connected with the rear cantilever; one end of the pressure spring is connected with the A point on the support frame, and the other end of the pressure spring is connected with the hinged point between the front connecting rod and the rear connecting rod. When the self-adaptive leveling chassis passes through uneven ground, by the self-adaptive adjustment of height of each suspension frame, the changes, caused by terrain change, of an inclination angle and a pitch angle of the chassis are reduced, dynamic leveling of the chassis is achieved, and operation requirements of an agricultural power chassis used on hilly sloping land are met.

Description

technical field [0001] The invention relates to an adaptive leveling chassis, which belongs to the technical field of agricultural machinery, and in particular to an adaptive leveling chassis of an agricultural vehicle on hilly and sloping land. Background technique [0002] my country's hilly and mountainous areas account for about 2 / 3 of the country's land area, grain production accounts for 1 / 3 of the country's total output, and economic and specialty crops account for more than 50% of the total, occupying a pivotal position in my country's agricultural production. With the acceleration of agricultural mechanization in our country, farmers have an increasingly urgent demand for small agricultural machinery suitable for hilly and sloping operations. However, the hilly and mountainous terrain is complex, the ground is uneven, and the stability of the vehicle chassis is poor, which affects the driving of the vehicle on hilly and sloping land. and operations, research on the ...
