Abstract: A preloading device (10, 100, 300) with a first end part (11, 111), with a second end part (12, 112) and with at least one spring device (F, F1, F2), which connects a second end part (12, 112) to the first end part (11, 111) along a spring device reference axis (RA, RA1, RA2), wherein the at least one spring device (F, F1, F2) is formed of at least one meander section (M1), each of which extends along the spring device reference axis (RA, RA1, RA2), and a drive device (1) with a preloading device (10, 100, 300).

Abstract: An adjusting device includes a base body, at least two drive elements, and a movable platform. Each of the drive elements abuts against a lever transmission device to perform a defined adjustment motion relative to the base body as a tilting motion about an axis through the platform and/or a translational motion parallel to an axis perpendicular to a platform plane. Joint elements allow for a tilting motion of the platform solely about the tilting axis. A spring element counteracts a parasitic translational motion in the platform plane and/or a parasitic rotatory motion of the platform about an axis of rotation arranged perpendicular to the platform plane due to the adjustment motion.
