Abstract

The invention discloses a single-piston stroke inductive type resistance change damping structure which comprises a cylinder. A piston is arranged in the cylinder and provided with a piston rod. A through hole with an opening is formed in the piston rod. A diameter-variable damping rod is arranged in the through hole or a variable outer damping pipe is arranged outside the piston rod. The piston rod is sleeved with the variable outer damping pipe. Damping is changed through the change of gaps between the diameter-variable damping rod arranged in the through hole, the through hole and the opening of the through hole, and an imitated damping programming manner is adopted, or damping is changed through the change of the size of the exposed portion, between the variable outer damping pipe and the through hole, of the opening of the through hole, and therefore variable damping is achieved.

Description

technical field [0001] The invention relates to a hydraulic damping structure, and more specifically, the invention relates to a single-piston stroke-inductive resistance variation damping structure. Background technique [0002] In the traditional hydraulic damping structure, the generation of damping force is basically realized by both the fixed damping oil hole and the pressure relief valve: the fixed damping oil hole restricts the flow of hydraulic oil to achieve the damping effect; Large flow reduces damping force. This is a simple pressure-sensitive damping structure, and the damping force can only decrease gradually as the pressure increases. It is not suitable for occasions where the damping force is required to increase or the dynamic changes of the increase or decrease are required. At present, the schemes to realize the controllable change of similar damping force are: 1. Adding an electronic control system, such as using a stepper motor to dynamically adjust th...
