Shaft having a journal

Abstract

A threaded spindle (11), having a drive part (20), which has a longitudinal axis (A) and is mounted in a first journal (70), and having a threaded part (30), which likewise has a longitudinal axis (B), and having a threaded nut (50), which is mounted in a second journal (80a; 80b) and in which the threaded part (30) is guided. The drive part (20) and the threaded part (30) are formed as separate parts and are each provided with at least one coupling element (25, 55), which are connected to each other in an articulated manner by plugging together. A mutual offset or inclination angle (a) of the longitudinal axes (A, B) of the drive part (20) and of the threaded part (30) can be compensated in this manner. The two-part threaded spindle (11) forms a threaded drive with the threaded nut (50) thereof, which can for example be used in a parking brake of a vehicle braking system. The swinging function created between the drive part (20) and the threaded part (30) reduces transverse forces, which increases efficiency and reduces wear compared to a known threaded drive with a single-part threaded spindle.
