An integrated planetary gearing system includes a reduction gear and a spur gear differential. First planets are arranged in a first planet plane. Second planets are arranged in a second planet plane. A planetary carrier includes a first carrier wall section, a second carrier wall section, and a third carrier wall section. The first and the second carrier wall section are spaced apart from one another axially and are formed by a base part. The third carrier wall section is formed by a cover element which is attached to the base part. The second carrier wall section carries a plurality of pockets, each receiving a planet of the second toothing plane. The cover element is attached to cover seat faces of the pocket bottoms, which cover seat faces in each case face away from the pocket interior.

Oldham couplings are disclosed, for example, for use in electric camshaft adjusters. The Oldham coupling may include a first outer connecting disk and a second outer connecting disk having axes of rotation extending parallel to each other and a central connecting disk including one or more through-bores. One or more connecting elements may couple the first outer connecting disk to the central connecting disk via the through-bore(s). A sleeve may be arranged in the through-bore(s) such that the connecting element(s) contacts the sleeve and wear of the central connecting disk is reduced. For example, the sleeve may prevent direct contact of the connecting element(s) with the central connecting disk, such as by a spacer or flange. The sleeve may be made of metal, while the central connecting disk may be plastic or metal.

A ball screw of an electromechanical brake comprising a ball screw nut disposed on a spindle, wherein the spindle includes complementary tracks formed on the spindle and the ball screw nut. The ball screw further includes a race that includes a plurality of ball pockets spaced apart from one another and a protruding section that includes a concave bearing surface, a ball housed between the concave bearing surface and an end section of a first spring element for a main load direction, and a second spring element for a return stroke direction, wherein the second spring element includes a second spring end section in contact with an opposite side of the bearing surface.
