Problems solved by technology

As a result, as a valve spring disposed between the valve body 41 and the connection support 47 to press the valve disc 43, the general floating piston valve uses a spiral wave type valve spring, which is expensive and requires a narrow installation area, Instead of tripod type leaf springs which are cheap and require a large mounting area

Embodiment Construction

[0019] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0020] Figure 4 is a cross-sectional view of a portion of an amplitude selective damper according to one embodiment of the present invention. As shown in the figure, the amplitude selective shock absorber according to this embodiment comprises: a cylinder 110; a piston rod 120 axially reciprocating in the cylinder 110; a stationary (stationary) piston valve 130 fixedly mounted on the piston rod 120, The space of the cylinder 110 is thus divided into a rebound (rebound) chamber and a compression chamber; a floating piston valve 140, mounted on the piston rod 120, so as to move axially in the rebound chamber; and a stopper 150, fixed to the piston rod 120, located above the floating piston valve 140. Figure 4 , the return spring and stop spring are omitted.

Abstract

A floating piston valve includes an annular valve body having a fluid passing hole formed therein, a pair of upper and lower valve discs respectively mounted on upper and lower sides of the valve body to generate damping force, a pair of upper and lower tripod type leaf valve springs respectively mounted on upper and lower sides of the upper and lower valve discs, and a pair of upper and lower coupling supports coupled to the valve body respectively at upper and lower sides of the upper and lower tripod type leaf valve springs. Each of the coupling supports includes an annular support section and a coupling section at least partially formed on an outer edge of the annular support section and is fastened to the valve body through a portion of an outer edge of the valve body.

Description

technical field [0001] The present invention relates to a floating piston valve for a shock absorber that dampens vibrations transmitted from the road surface to a vehicle, and more particularly to a floating piston valve for an amplitude selective shock absorber that responds to a high frequency vibration input to provide Characterized by low damping force, this vibration has a low amplitude and occurs frequently, thereby improving the driving comfort of the vehicle. Background technique [0002] Generally, a vehicle is provided with a suspension system for improving driving comfort by absorbing or alleviating shock or vibration transmitted from a road surface to an axle during driving on the road surface. One component of the suspension system is the shock absorber. The shock absorber is disposed between an axle and a vehicle body, and includes a cylinder and a piston rod that can reciprocate in the cylinder. The cylinder is filled with a damping fluid, such as gas or oi...
