Hydraulic control system for self-balancing of agricultural machinery vehicle body

Abstract

The invention relates to an agricultural machinery suspension system, in particular to a hydraulic control system for self-balancing of an agricultural machinery vehicle body. The hydraulic control system for self-balancing of the agricultural machinery vehicle body comprises a hydraulic power system, an electronic control unit electrically connected with the hydraulic power system, and a whole-vehicle hydraulic suspension system arranged on a machine body; and the whole-vehicle hydraulic suspension system is connected with the electronic control unit through an oil tube and a wire, the machine body is further provided with a sensor device which is electrically connected with the electronic control unit. According to the hydraulic control system, the relative vehicle body displacement condition and the vehicle body swinging condition of all wheels are detected through the sensor device, the detected parameters are transmitted to the electrical control unit in an electrical signal mode,the electronic control unit sends the current with the corresponding magnitude to the whole-vehicle hydraulic suspension system according to the actual control requirement, and thus the vehicle bodylifting direction and the lifting amount are determined; and besides realizing automatic position adjusting of a lifting mechanism of the agricultural machinery vehicle body, the ride comfort of a vehicle is improved, and the comfortableness of a damping system is improved.

Description

technical field [0001] The invention relates to an agricultural machinery suspension system, more specifically, to a hydraulic control system for the self-balancing of the agricultural machinery body. Background technique [0002] The working road conditions of agricultural machinery are often uneven, tortuous, and have slopes. The suspension system used in traditional agricultural machinery is mostly non-independent suspension (leaf spring + passive shock absorber). The vehicle fluctuates greatly during operation and the vibration is very severe. This not only affects the stability of the vehicle's direction control, but also easily causes the driver to Fatigue, especially the body will tilt, prone to overturning, and the life of the vehicle is short. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hydraulic control system for the self-balancing of the agricultural machine body.
