MULTIPURPOSE HYDRAULIC SHOCK-ABSORBER FOR VEHICLE

摘要

FIELD: mechanical engineering. ^ SUBSTANCE: shock-absorber comprises controlled means (70) and (71) that determine shock-absorbing in compression phase and are mounted in head (61) of tank and accessible from inside. Means (71) comprises tubular housing (75) for control of preliminary loading that is screwed in head (61) of the tank and provided with the outer control head (75a). Tubular housing (75) is made for permitting connection with the chamber with greater cross-section of the shock-absorber. Tubular housing (75) receives control screw (70) that passes through it in the axial direction and is screwed in its vertical top part. The end of the screw that enters the tank is provided with valve (72) provided with spring means for calibration and at least one radial groove (81) that defines leakage passage for determining preliminary loading. The cross-section of the passage is determined by the distance between face (82) of tubular housing (75) and inner side (61a) of head (61) of the tank. ^ EFFECT: expanded functional capabilities. ^ 9 cl, 15 dwg
