Description

Technical Field

[0001] The utility model relates to the field of a linking ring structure, in particular to a polygonal linking ring structure between an electromagnetic valve of an electric-controlled shock absorber and an intermediate cylinder. Background Art

[0002] Shock absorbers generally generate damping force through the flow of oil inside them. When vibration occurs during driving, the spring part drives the shock absorber piston to move up and down inside the shock absorber, and the oil in the shock absorber cavity flows repeatedly from one cavity to another in accordance with the movement. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into oil heat energy, which is then absorbed by the shock absorber and distributed into the atmosphere.

[0003] Compared with traditional shock absorbers, the electronically controlled shock absorber has an additional electromagnetic valve and intermediate cylinder structure. During normal operation, the current in the electromagnetic valve can be adjusted as needed to affect the opening of the electromagnetic valve through hole, and then when the oil in the intermediate cylinder flows to the node of the electromagnetic valve, its flow state is affected, so that the damping force in the electronically controlled shock absorber can be continuously adjusted;

[0004] In normal production, different manufacturers have corresponding standard specifications for solenoid valves and intermediate cylinders. Therefore, in order to ensure good coordination of the structure and sealing between the two, a link ring is generally used to connect the two components. The commonly used link ring structure under current technology is generally made of threaded connection, welding, or the intermediate cylinder oil through hole with a flange and a link ring.

When vibration occurs during driving, the spring part drives the shock absorber piston to move up and down inside the shock absorber, and the oil in the shock absorber cavity flows repeatedly from one chamber to another in accordance with the movement. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into oil heat energy, which is then absorbed by the shock absorber and distributed into the atmosphere. Compared with traditional shock absorbers, the electronically controlled shock absorber is equipped with an additional solenoid valve and intermediate cylinder structure. During normal operation, the current in the solenoid valve can be adjusted as needed to affect the opening size of the solenoid valve through hole, and then when the oil in the intermediate cylinder flows to the node of the solenoid valve, it affects its flow state, thereby realizing continuous adjustment of the damping force in the electronically controlled shock absorber.
