Embodiment 1

[0027] see figure 1 , a double-layer self-adjusting suspension suitable for hilly areas mainly includes two parts: one is the lower hydraulic independent adjustment suspension, and the other is the upper hydraulic synchronous interconnection suspension. The two are used together in different working modes.

[0028] The prime mover 1 is the power source of the entire hydraulic system. The power element of the lower hydraulic independent adjustment suspension is the gear pump 2. The oil outlet of the gear pump is divided into three ways, and one way is connected to the pressure gauge 6 for displaying the system pressure. One way is connected to the safety valve 3 to ensure that the system pressure is within the set range. The set pressure is 150% of the rated working pressure of the lower hydraulic suspension system. The oil outlet of the safety valve 3 is connected to the cooler 5. The cooling capacity should be matched according to the walking speed of the vehicle. If the wal...

Embodiment 2

[0033] The structure of the double-layer automatically adjustable suspension suitable for hilly and mountainous areas of this embodiment is the same as that of the embodiment, but the control method is different:

[0034] see Figure 1-2 , when the second level sensor J6 monitors that the degree of inclination reaches the set value, the control system automatically executes the climbing mode: uphill state: the two upper suspension rear frame hydraulic cylinders 21 stretch out to level the upper frame; Downhill state: two upper suspension front frame hydraulic cylinders 20 stretch out to level the upper frame; when the second level sensor detects that the degree of inclination is less than the set value, the first level sensor J5 implements real-time monitoring. When the instability of the monitoring value of the first level sensor is greater than the set value, the control system automatically executes the uneven road driving mode: the first level sensor J5 works, monitors the...

Abstract

The invention relates to a double-layer automatically adjustable suspension suitable for hilly mountainous areas. Each of four corner parts of a lower hydraulic pressure independent adjustment suspension is provided with a lower suspension hydraulic function unit, and the middle parts of four beams of a lower suspension is provided with first horizontal sensors; each lower suspension hydraulic function unit is independently controlled, and the levelness of the lower suspension is adjusted in real time according to the monitoring data of each first horizontal sensor; an upper hydraulic synchronous interconnect suspension is fixedly arranged on the upper part of the low suspension, and the upper suspension hydraulic functional units are divided into two groups of upper suspension front framehydraulic functional units and upper suspension rear frame hydraulic functional units, and each group is provided with a synchronous motor; second horizontal sensors are arranged in the middle of thecross beams on both sides of the upper suspension, and a pair of hydraulic cylinders on each of the front and rear sides of the lower suspension are synchronously controlled. The four suspension independently and automatically adjust a driving posture of the vehicle in real time when the vehicle is traveling on the uneven road surface. At that same time, the level of the drive's sitting posture can be kept when the vehicle ascends or descend a slope.

Description

technical field [0001] The invention relates to a suspension, in particular to a double-layer self-adjustable suspension suitable for hilly and mountainous areas. Background technique [0002] In my country, the area of ​​hilly and mountainous areas accounts for more than 1 / 3 of the country's land area. In this area, there are phenomena of low operating efficiency, poor quality, and low safety. Its mode of production is still dominated by traditional small-scale machinery and human and animal power, which has resulted in an extreme imbalance in the development of mechanization among regions. Most of the plain areas have entered the intermediate stage of mechanization, and some have entered the advanced stage of agricultural mechanization, but hilly areas are still in the agricultural mechanization stage. primary stage of transformation. It can be said that the short board of my country's mechanization development lies in the hilly and mountainous areas, and the upgrading po...
