FREQUENCY SENSITIVE SHOCK ABSORBER

摘要

A shock absorber is disclosed herein with a frequency sensitive damping force that includes a cylinder containing a damping medium, a piston rod which is axially movable in the cylinder, and a piston assembly arranged for axial movement in the damping medium. The piston assembly is connected to the piston rod and divides the cylinder in a working space on each side of the piston. The piston assembly includes a flow path fluidly coupled to a frequency sensitive element movable relative to the piston assembly.

主权项

1. A frequency sensitive shock absorber, comprising:
a cylinder containing a damping medium; a piston rod positioned for axial movement within the cylinder along a central axis; a piston assembly coupled to the piston rod and arranged for axial movement in the damping medium along the central axis to separate the cylinder into a first working space on a first side of the piston assembly and a second working space on a second side of the piston assembly, the piston assembly including: a first flow path allowing flow of the damping medium therein and extending from the first side to the second side; a second flow path distinct from the first flow path, allowing flow of the damping medium therein extending from the first side to the second side; and a movable element positioned in the second flow path and movable along the second flow path with respect to the piston assembly.
