Adaptive leveling suspension

Abstract

The invention belongs to the technical field of agricultural machines, and discloses an adaptive leveling suspension. The adaptive leveling suspension comprises a front cantilever, a rear cantilever, a front tension spring, a rear tension spring, a supporting rod, wheels and a support, wherein one end of the front cantilever, one end of the rear cantilever and one end of the supporting rod are connected in a rotating mode around a point A on the support, the other end of the front cantilever and the other end of the rear cantilever are connected with the wheels in a rotating mode respectively, the other end of the supporting rod is connected with the front tension spring and the rear tension spring, and the other end of the front tension spring and the other end of the rear tension spring are connected with the front cantilever and the rear cantilever respectively. Four or six adaptive leveling suspensions are installed on the same frame through supports and are symmetrically arranged about the central longitudinal plane of the frame according to a set axle base and a set wheel track, and an adaptive leveling chassis is formed. When the chassis passes through an uneven ground, adaptive adjustment of the height is conducted through the suspensions, the variation, caused by terrain changes, of the roll angle and the pitch angle of the chassis is reduced, dynamic leveling of the chassis is achieved, and the working requirement of an agricultural power chassis on a hilly slope is met.

Description

technical field [0001] The invention relates to an adaptive leveling suspension, which belongs to the technical field of agricultural machinery, and in particular to a horizontal adjustment suspension of an agricultural power chassis on hills and slopes and a power chassis for hills and slopes equipped with the suspension. 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 driv...
