SHOCK-ABSORBER Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: signal is fed to electromagnet 8 from a control system when a flying vehicle have been passed the trajectory leg of maximum vibration level. Armature 9 is drawn in and loosens locators 11 which are pressed to bushing 6 with springs 12. As static axial overloading increases, faces of locators 11 move along bushing 6 up to the coincidence of the bushing ring groove with the faces of the locators. The locators enter the ring groove under the action of springs 12 and further axial movement of bushing 6 stops. In so doing, the shock- absorber becomes absolutely rigid in axial direction and keeps vibration insulation in the side directions. EFFECT: enhanced reliability. 2 dwg
