Double-layer automatically adjustable suspension suitable for hilly mountainous areas

Abstract

The invention relates to a double-layer automatically adjustable suspension suitable for hilly mountainous areas. Each of four corner parts of a lower hydraulic pressure independent adjustment suspension is provided with a lower suspension hydraulic function unit, and the middle parts of four beams of a lower suspension is provided with first horizontal sensors; each lower suspension hydraulic function unit is independently controlled, and the levelness of the lower suspension is adjusted in real time according to the monitoring data of each first horizontal sensor; an upper hydraulic synchronous interconnect suspension is fixedly arranged on the upper part of the low suspension, and the upper suspension hydraulic functional units are divided into two groups of upper suspension front framehydraulic functional units and upper suspension rear frame hydraulic functional units, and each group is provided with a synchronous motor; second horizontal sensors are arranged in the middle of thecross beams on both sides of the upper suspension, and a pair of hydraulic cylinders on each of the front and rear sides of the lower suspension are synchronously controlled. The four suspension independently and automatically adjust a driving posture of the vehicle in real time when the vehicle is traveling on the uneven road surface. At that same time, the level of the drive's sitting posture can be kept when the vehicle ascends or descend a slope.

Description

technical field

[0001] The invention relates to a suspension, in particular to a double-layer self-adjustable suspension suitable for hilly and mountainous areas. Background technique

[0002] In my country, the area of ​​hilly and mountainous areas accounts for more than 1 / 3 of the country's land area. In this area, there are phenomena of low operating efficiency, poor quality, and low safety. Its mode of production is still dominated by traditional small-scale machinery and human and animal power, which has resulted in an extreme imbalance in the development of mechanization among regions. Most of the plain areas have entered the intermediate stage of mechanization, and some have entered the advanced stage of agricultural mechanization, but hilly areas are still in the agricultural mechanization stage. primary stage of transformation. It can be said that the short board of my country's mechanization development lies in the hilly and mountainous areas, and the upgrading po...
