    • The invention relates to an electric motor comprising an inner rotor (1) and an outer rotor (20). Said rotor (1) is embodied, in the cross-section, as a rotor ring (12) that is made of ferromagnetic material, comprising recesses (7), that are distributed in a circular manner, for permanent magnets (5), such that said rotor ring (12) is divided in the rotor poles (4) and said permanent magnets (5) are embodied, in the cross-section, in a rectangular manner, forming the width (b) and the height (h) and the height (h) forms the longest side which faces away from the motor axis (2) in the radial direction and the permanent magnets (5) are magnetised in the direction of the width (b) thereof and are oriented counter to each other on the same pole in the rotor ring (12). The invention is characterised in that for each inner part of a rotor pole (4) that is between two adjacent permanent magnets (5), a magnetic recess (11, 11') is embodied from the end region of the permanent magnets (5) oriented towards the motor axis (2) in such a manner that in the respective central areas of the rotor pole (4), in the radial direction for each rotor pole (4), a supporting web (10) that supportingly connects, in a mechanical manner, an inner supporting ring (8) to the respective rotor pole (4), is embodied.

    • The invention relates to a variable-length steering spindle for steering devices of motor vehicles, comprising an outer sleeve-shaped profile (1) with a non-circular cross section, an inner profile which has a non-circular cross section and which can be pushed with an end section into the outer profile (1), wherein the inner peripheral contour of the outer profile (1) and the outer peripheral contour of the inner profile (2) are formed at least partially from arc-shaped sections and said arc-shaped sections form, preferably alternating, convex and concave sections (9, 10, 12, 13) both of the outer profile (1) and also of the inner profile (2), which convex and concave sections (9, 10, 12, 13) point towards the gap space (6) situated between the outer profile (1) and the inner profile (2), and the convex sections (13) of the outer profile (1) are at least partially situated opposite the concave sections (9) of the inner profile (2) and/or the concave sections (12) of the outer profile (1) are at least partially situated opposite the convex sections (10) of the inner profile (2), and a sliding sleeve (7) which is arranged in the gap space (6) and which is held so as to be non-rotatable with respect to one of the two profiles (1, 2) and so as to be immovable in the longitudinal direction and which, together with the profile (2) which retains the sliding sleeve (7), is movable in the longitudinal direction, but substantially non-rotatable, with respect to the other profile (1), characterized in that rolling bodies (15) are arranged in recesses (14) of the sliding sleeve (7), which rolling bodies (15), on that side of the sliding sleeve (7) on which the profile which is longitudinally movable with respect to the sliding sleeve (7) is situated in the assembled state, project out of the sliding sleeve (7) at least in their unloaded state, and which rolling bodies (15), in the assembled state of the steering spindle, are in each case preloaded against a surface (16), which forms a raceway, of the profile (1) which is longitudinally movable with respect to the sliding sleeve (7), and which rolling bodies (15) are movable in a direction away from the raceway counter to a restoring force, wherein in the event of a limit value of the torque acting between the two profiles (1, 2) being exceeded, contact occurs between the surface (17) of the sliding sleeve (7) and the surface (16) of the profile (1) which is longitudinally movable with respect to said sliding sleeve (7).

    • Eine Feststelleinrichtung einer in mindestens eine Verstellrichtung (46) verstellbaren Lenksäule, umfasst mindestens ein der Verstellrichtung (46) oder einer der Verstellrichtungen zugeordnetes Feststellteil (20, 21), mindestens ein dieser Verstellrichtung (46) zugeordnetes Gegenfeststellteil (14, 15) und eine offen- und schließbaren Spannvorrichtung, in deren geöffnetem Zustand erste und zweite Verzahnungen (38, 39) Feststellteils (20, 21) von ersten und zweiten Gegenverzahnungen (40, 41) des Gegenfeststellteils (14, 15) beabstandet sind und in deren geschlossenem Zustand das Feststellteil (20, 21) und das Gegenfeststellteil (14, 15) miteinander in Zahneingriff stehen. Die Ebenen (47, 48; 49, 50) der Spitzen der Zähne (42, 43; 44, 45) der ersten und zweiten Verzahnungen (38, 39) bzw. ersten und zweiten Gegenverzahnungen (40, 41) stehen V-förmig zueinander und zwischen den Zähnen (42, 43; 44, 45) der ersten und zweiten Verzahnung (38, 39) oder der ersten und zweiten Gegenverzahnung (40, 41) liegt in Verstellrichtung (46) ein Versatz (v) vor, der einen Teil des Abstands (a) zwischen aufeinanderfolgenden Zähnen (42 bis 45) beträgt (Fig. 4).
