Problems solved by technology

However, the backhoe loader is affected by the structure of the working device at the loading end. When it is excited by the uneven road surface, the uneven road surface will cause vibration and jolt of the whole vehicle, which is mainly manifested as front and rear pitching vibration.
Due to the influence of the load of the working device at the loading end, which is similar to the cantilever beam structure at the front, the movement of the center of gravity of the vehicle further amplifies this vibration, resulting in more serious longitudinal pitching vibrations
On the one hand, this will lead to poor operating comfort, and on the other hand, the material in the hopper will easily spill due to longitudinal pitching vibration, thereby reducing the working efficiency
Therefore, this vibration problem has seriously restricted the development of backhoe loaders in high speed, high efficiency and safety.

Abstract

The invention relates to a driving stabilizing system, a backhoe loader and a control method. The driving stabilizing system comprises a hydraulic actuator (1), a first hydraulic oil source (B), an energy storage element (A) and a controller (E), wherein the first hydraulic oil source (B) is operably connected with the hydraulic actuator (1) and is configured to provide pressure oil for the hydraulic actuator (1); the energy storage element (A) is operably connected with a first oil supply oil way (r1) between the first hydraulic oil source (B) and the hydraulic actuator (1); and the controller (E) is configured to compare the oil pressure of the hydraulic actuator (1) to the oil pressure of the energy storage element (A) after the driving stabilizing system is started, and enable the oilpressure of the energy storage element (A) and the oil pressure of the hydraulic actuator (1) to be balanced before the energy storage element (A) is connected into the first oil supply oil way (r1).

Description

technical field [0001] The present disclosure relates to the field of engineering machinery, and in particular to a driving stability system, a backhoe loader and a control method. Background technique [0002] The backhoe loader is a multifunctional construction machine integrating digging and loading. It is widely used in the construction of various basic engineering projects, and can be engaged in multiple operations such as excavation, shoveling, carrying, crushing and leveling the site. Because they often need to travel on various complex and even harsh off-highway roads, they are required to have a higher driving speed to improve work efficiency. However, the backhoe loader is affected by the structure of the working device at the loading end. When it is excited by the uneven road surface, the uneven road surface will cause vibration and jolt of the vehicle, mainly manifested as front and rear pitching vibration. Due to the influence of the load of the working device...
