  • Patent number: 8800732
    Abstract: A hydraulic damper assembly includes a main body, a shaft assembly and a main piston operatively configured to define an upper portion and a lower portion within the main body. A hydraulic damper spool valve is adapted to provide a single path, variable hydraulic flow restriction between the upper portion and lower portion of the main body. The hydraulic damper spool valve is configured with an array of precisely shaped flow apertures that are proportionally opened and closed by a pair of valve spools in response to the pressure differential across the main piston. The damper's pressure-flow operating characteristic is simply and predictably dictated by the geometric configuration of the shaped flow apertures. The precisely defined open area of the shaped flow apertures provides a mathematically predictable hydraulic flow restriction that operates predominately in a turbulent regime resulting in insensitivity to hydraulic fluid viscosity and consequently temperature change.

  • Publication number: 20130313801
    Abstract: A twist beam is manufactured from a tube and has a shorter sectional perimeter in the “V” or “U” shape center section and a longer sectional perimeter at the beam ends. The present disclosure therefore proposes to use a tubular member having a predetermined length. The tubular member is deformed at the center section of the tube into a “V” or “U” shape and then expanded at both end portions. This structure is formed using a closed die internal pressure forming process such as hydro-forming or blow molding or the like. The ends of the tubular member may also have a substantially oval or rectangular section. The tubular member of the present disclosure may also be heat treated in the closed die internal forming process to achieve a higher material strength. In this manner, the twist beam of the present disclosure is optimized to used the smallest possible section along its entire length, thus has a substantially lower mass and can be manufactured using less material and therefore at a substantially lower cost.
