Abstract

The invention provides a suspension system control method, which comprises the following steps: judging whether frame angle of inclination exceeds the preset angle of inclination, if the angle of inclination does not exceed the preset angle of inclination, lifting and descending a suspension system; and otherwise, stopping lifting the suspension system. Additionally, the invention also provides the suspension system and a crane thereof; the suspension system comprises a tilt sensor, a height sensor and a suspension controller, wherein the tilt sensor is arranged on a revolving platform of a vehicle and is used for detecting the angle of inclination of the frame; the height sensor is arranged in the suspension system and is used for detecting the height of each suspension pivot in the suspension system; and the suspension controller controls the suspension system to lift and descend through the different value of the angle of inclination and the height of each suspension pivot. The suspension system can monitor the incline angle of the crane in real time, can give an alarm and stops the lifting and descending of the suspension system once the angle of inclination exceeds the preset value, can effectively prevent the crane from tipping over, and improves the safety of the crane when the suspension system is lifted.

Description

technical field

[0001] The invention relates to a control method for vehicle running, in particular to a control method for a suspension system of a vehicle. In addition, the invention also relates to a suspension system and a crane with the system. Background technique

[0002] Oil-pneumatic suspension technology is widely used in vehicle chassis. During the application and operation of all-terrain crane chassis oil-pneumatic suspension, the operator blindly operates in the cab. Knowing the current lifting position of the suspension, and not knowing the level of the vehicle, there is a risk of the vehicle tipping over when there is no one nearby to command, misoperation occurs, or a partial failure of the system occurs. Especially in some complicated road conditions, the visual lifting height can easily cause the whole vehicle to tilt and roll over.

[0003] In addition, an important feature of the oil-pneumatic suspension system is that it can adjust the height of the ve...
