Adjustable height spring holder comprises axially movable spring plate and activator comprising rotor generating rotational movement relative to stator converted to spring plate axial movement by conversion device

摘要

The spring holder comprises an axially movable spring plate (35) and an activator (3) comprising a rotor (17) which generates a rotational movement relative to its stator (11), which is converted into an axial movement of the spring plate by a movement conversion device (27). A torque casing device preventing rotational movement of the spring plate comprises an anti-rotation locking element (29) which is stationary relative to the casing (9) of the activator and is connected to the spring plate.
