Description

Technical Field

[0001] The utility model relates to the technical field of suspension, in particular to a buffer block for suspension. Background Art

[0002] The buffer block used in the suspension system is a key technical component. Its main function is to reduce the impact and vibration generated by the suspension system during driving, and improve driving comfort and stability. The main role of the buffer block in the suspension system is to absorb and reduce the impact and vibration from uneven road surfaces, braking and acceleration.

[0003] However, the existing buffer block design usually fixes it at the bottom of the cylinder body, and is sleeved on the outer surface of the piston rod through the connection hole inside the buffer block to mitigate the impact and vibration of the piston rod when it moves up and down. However, over time and long-term use, this design may face some problems. Since the piston rod exerts pressure on the buffer block during movement, especially after repeated squeezing and movement, the connection hole on the buffer block may gradually expand. This situation causes the connection hole to lose its original tightness and stability, making the buffer block possible to be misplaced or moved during operation. This misalignment not only affects the performance of the suspension system, but may also cause abnormal noise, additional friction, or even accelerate the wear of components. Utility Model Content

[0012] As a preferred implementation, the outer sides of the four first hinges are movably connected with first dampers, and the outer surfaces of the four first dampers are provided with second return springs.

[0013] The technical effect of adopting the above further solution is that the first damper and the second return spring can be contracted.

[0014] As a preferred embodiment, the other ends of the four first dampers are movably connected to a second hinge, the four second hinges are divided into two groups, and two second dampers are fixedly installed on opposite sides of the two connecting members.

[0018] As a preferred embodiment, the inner surfaces of the two third return springs are movably sleeved on the outer surface of the second damper, wherein the outer surface of another connecting plate is fixedly sleeved with a mounting bowl.

[0019] The technical effect of adopting the above further solution is that the rubber buffer block body can be fixed to the lower part of the cylinder body by means of the mounting bowl.
