Embodiment 1

[0009] Example 1: refer to the attached figure 1 . The cylinder block of the double-shaft gas spring is a left and right cavity, the pistons in the left and right cavities are respectively provided with through holes, and one end of the left and right shafts respectively passes through the shaft holes in the left and right end covers of the cylinder block, respectively, and one end face of the left and right pistons The shaft connecting the left and right shafts is provided with grooves, the left and right shaft rotating sleeves are respectively sleeved on the left and right shafts, and the left and right shaft rotating sleeves are respectively provided with small holes, and the shafts are solid shafts or hollow shafts. That is to say, the middle of the cylinder block 10 of the double-shaft gas spring is provided with a plunger partition 13 and divides the cylinder block 10 into left and right cavities. The middle of the plunger partition 12 and the cylinder are provided with ...

Embodiment 2

[0010] Embodiment 2: On the basis of Embodiment 1, the working method of the double-shaft gas spring, the middle of the cylinder block 10 is provided with a plunger partition 13 and the cylinder block 10 is divided into left and right cavities, the middle of the plunger partition 12 and the column The body is provided with a guide hole 12, the guide rod 15 is located in the guide hole 12 and stretches along the guide hole, the right cavity piston 16 is sleeved on the guide rod 15 and is located in the right cavity 14 of the gas cylinder, and the right cavity piston has a through small hole. Hole 17, one end of the shaft 21 passes through the shaft hole in the end plate of the gas cylinder and is connected to the end face of the right cavity piston 16, and the shaft 21 is provided with a groove 19, and the shaft rotating sleeve 20 is sleeved on the shaft 21 and has a small hole on it. Hole 22, the left cavity piston 23 is sleeved on the plunger part of the plunger partition 13 a...

Embodiment 3

[0011] Example 3: On the basis of Example 2, when the left and right pistons need to be extended at the same time, the small hole on the shaft rotating sleeve and the small hole on the hollow shaft rotating sleeve are sealed with the shaft and the hollow shaft. The area of ​​the left and right chambers in the left chamber piston chamber is equal, and the area of ​​the left and right chambers in the right chamber piston chamber is equal.

Abstract

The invention relates to a double-axis air spring structure and an operating method thereof. The air cylinder of the double-axis air spring has a left cavity and a right cavity. Pistons of the left and right cavities have a through hole respectively. One end of a left shaft and one end of a right shaft respectively pass through shaft holes on a left end cover and a right end cover to connected with an end face of the left piston and an end face of the right piston respectively, and a shaft lever of the left shaft and a shaft lever of the right shaft have a grove respectively. A left shaft rotating sleeve and a right shaft rotating sleeve are respectively sleeved on the left shaft and the right shaft and have a small hole respectively. The double-axis air spring structure and the operating method thereof have the advantages of: 1. realizing the unidirectional expansion as well as the bidirectional expansion of the air spring; 2. a structure designed to be novel, unique, simple and practical.

Description

technical field [0001] The invention relates to a structure and a working method of a biaxial gas spring, and belongs to the field of gas spring manufacturing. Background technique [0002] Publication number CN1975194A, name "gas spring", it is a closed air compression system formed by setting a damping air passage between the main elastic air cavity and the auxiliary elastic air cavity formed by the piston body separating the cylinder block, and using the damping air passage to damp the medium. The main elastic air cavity and the auxiliary elastic air cavity have unequal gas pressures due to the action of force. When the piston body moves up and down under the action of external force, that is, when the gas spring is compressed or elongated, it can press close to "real-time". The optimal working condition automatically adjusts its stiffness change to balance the effect of external force. The disadvantage: it can only be stretched or compressed in one direction.
