AI Technical Summary
When existing buffers have a choke channel on the piston, it is difficult to set the damping force characteristics and cannot effectively increase the damping force during low-speed extension and retraction. In addition, increasing the axial length of the piston will sacrifice the stroke length of the buffer.
A disc-shaped separator is used in the buffer. By setting a spiral air choke channel on the outer or inner periphery of the port of the separator, the channel length is increased without increasing the axial length of the separator. The complex air choke channel structure is manufactured using a 3D printer.
It increases the design freedom of the choke channel length, can increase the damping force during low-speed extension and contraction, and simplifies the setting of damping force characteristics, avoiding the use of throttle orifices.
