Publication number: 20180306250Abstract: Release bearings for actuating a clutch are provided, and may include a bearing ring arranged non-rotatably on a sliding sleeve mounted on a transmission input shaft and a rotatable bearing ring, which interacts with a spring of the clutch. A row of rolling elements may be arranged radially between the two bearing rings and have pressure lines oriented obliquely with respect to a bearing longitudinal axis. The rolling elements may each be bodies of revolution with a circular-arc-shaped generatrix, wherein a center angle between radii bounding the circular-arc-shaped generatrix is smaller than 180°. The non-rotatable bearing ring may have a raceway shaped complementary to a shape of the rolling elements and may guide the rolling elements in an axial direction. The rotatable bearing ring may have a raceway shaped as a spherical surface with a sphere radius corresponding to the generatrix of the rolling elements.Type: ApplicationFiled: September 5, 2016Publication date: October 25, 2018Applicant: Schaeffler Technologies AG & Co.

Patent number: 8690447Abstract: A ball roller bearing, which has an outer and inner bearing ring with a groove-shaped raceways and ball rollers, which roll between the bearing rings in the raceways. The rollers are held at distances from each other in the circumferential direction by a bearing cage and which have a width that is dimensioned larger than the radial distance between the inside and the outside of the bearing rings. The raceways are divided into two segments by an axially centered annular groove such that a first ball roller rolls on two first diagonally opposed track segments and a second ball roller rolls on two second diagonally opposed track segments of the bearing rings. Both bearing rings are single-piece components, and the bearing cage is formed by two identical double prong-type cages acting independently of each other. The bearing is filled with the ball rollers by an axial tilt cam assembly method.Type: GrantFiled: March 19, 2010Date of Patent: April 8, 2014Assignee: Schaeffler Technologies AG & Co.
