Problems solved by technology

[0003] Although the leaf spring suspension currently used in cranes can meet the needs of cranes for a period of time, it has the following disadvantages: the ride comfort and comfort of the car are poor, and the unsprung mass is large, which cannot adapt to the development of lightweight heavy trucks. , and the comfort and handling stability of the crane cannot be taken into account at the same time
Therefore, with the improvement of crane operating conditions and performance, as well as the u

Abstract

The invention discloses an air suspension control system and method for a crane and the crane and relates to the field of engineering machinery. The air suspension control system comprises an altitude sensor, a pressure sensor and a controller. The altitude sensor transmits a measured height of suspension airbag to the controller; the pressure sensor transmits a measured pressure of the suspension airbag to the controller; and the controller outputs a control signal to an executing component according to the height and pressure of the suspension airbag and a selected mode to control the attitude and pressure of the suspension airbag and respectively maintain the attitude and pressure of the suspension airbag within an attitude range and a pressure range in the selected mode, and when mode switching is needed, the controller controls the executing component to execute switching among modes, wherein the modes include a highway driving mode, an off-road driving model and a hoisting operation mode. The invention realizes control of the different modes of the air suspension and switching among the modes.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an air suspension control system and method for a crane and the crane. Background technique [0002] At present, the suspensions commonly used on cranes include leaf spring suspensions (hereinafter referred to as leaf spring suspensions) and oil-pneumatic suspensions. Leaf spring suspension is widely used in truck cranes due to its simple structure, easy manufacture, and relatively low cost. The oil-pneumatic suspension is widely used in all-terrain cranes that require higher passing performance due to its height adjustable within a certain range and high comfort. [0003] Although the leaf spring suspension currently used in cranes can meet the needs of cranes for a period of time, it has the following disadvantages: the ride comfort and comfort of the car are poor, the unsprung mass is large, and it cannot adapt to the development of lightweight trucks , and cannot take i...
