Abstract

The invention provides a hill and mountain tractor body attitude adjusting device and an adjusting method. Axle adjusting components of the hill and mountain tractor body attitude adjusting device are symmetrically mounted at the bottom of a body; the hill and mountain tractor body attitude adjusting device comprises axles, attitude adjusting hydraulic cylinders, stabilizers and variable connecting rod groups; the attitude adjusting hydraulic cylinders and the variable connecting rod groups are both symmetrically hinged between the body and the axles; each variable connecting rod group comprises two connecting rods, which are hinged between the body and the axles and parallel to each other in an up-and-down direction; the stabilizers are mounted between the body and the axles; an electronically controlled hydraulic system comprises a sensor, a signal collection unit, an attitude controller and an electronically controlled hydraulic valve which are connected with each other via signals; and the electronically controlled hydraulic valve controls the attitude adjusting hydraulic cylinders. According to the adjusting method, vehicle attitude information detected by the sensor is transmitted to the attitude controller by using the information collection unit, and then the electronically controlled hydraulic valve is controlled to adjust the attitude adjusting hydraulic cylinders, and finally, self-adjusting of body attitude is realized. According to the hill and mountain tractor body attitude adjusting device and the adjusting method, the body attitudes of wheeled vehicles are self-adjusted in real time to guarantee the running stability.

Description

technical field [0001] The invention belongs to the technical field of body leveling of a tractor in hilly and mountainous areas, and in particular relates to a device and method for adjusting the body posture of a tractor in hilly and mountainous areas. Background technique [0002] Hilly and mountainous areas have the characteristics of complex terrain and many slopes. As the main source of power for agricultural production in hilly and mountainous areas, tractors in hilly and mountainous areas have a direct impact on the level of agricultural production in hilly and mountainous areas due to their safety and operating efficiency. At present, the agricultural machinery equipment used in hilly and mountainous areas in my country basically uses the original equipment in plain areas, and the adaptability to slopes is poor. In the process of operation in hilly and mountainous areas, the posture of the body is unstable due to the complex terrain, and field operations are difficul...
