Embodiment Construction

[0029] figure 1 Shows a three-dimensional view of a segmented rolling bearing 1 comprising a bearing housing 2 with a curved raceway 2c for the rolling elements 3 and a segmented cage 4 comprising several rolling elements Body 3. The bearing sleeve 2 has on its two longitudinal sides 2 a , 2 b respectively guide webs 5 , 6 for laterally guiding the segmented cage 4 , wherein each guide web 5 , 6 is substantially perpendicular to the bearing sleeve The raceway 2c of 2 is oriented. Each guide tab 5, 6 has a cutout 7 at each of its two ends 5', 5"; 6', 6", perpendicular to the longitudinal sides 2a, 2b of the bearing sleeve 2 In such a way that guide web sections 5 a , 5 b ; 6 a , 6 b are formed on both ends 20 , 21 of bearing sleeve 2 on both sides. The guide web sections 5 a , 5 b ; 6 a , 6 b are bent in the direction of the raceway 2 c and form end stops for the segmented cage 4 . The overall length L of the bearing sleeve 2 (compared to image 3 ) extends between the tw...

Abstract

The invention relates to a segment rolling bearing (1, 1', 1'') comprising a bearing shell (2) with a curved track (2c) for rolling elements (3) and a segment cage (4) comprising a number of rolling elements (3), wherein the bearing shell (2) has a respective guiding strip (5, 6) on its two longitudinal sides (2a, 2b) for lateral guiding of the segment cage (4), wherein each guiding strip (5, 6) is aligned perpendicular to the track (2c) of the bearing shell (2), wherein each guiding strip (5, 6) has at least one incision (7) at each of its two ends (5', 5''; 6', 6''), said incision being formed perpendicular to the longitudinal side (2a, 2b) of the bearing shell (2) in such a way that guiding strip sections (5a, 5b; 6a, 6b) are formed on one or both sides on the two ends (20, 21) of the bearing shell (2), and wherein the guiding strip sections (5a, 5b; 6a, 6b) are bent in the direction of the track (2c) and form end stops for the segment cage (4). The invention further relates to a disk brake device comprising a segment rolling bearing (1, 1', 1'') of this type.

Description

technical field [0001] The invention relates to a segmented rolling bearing comprising a bearing sleeve with arched raceways for rolling elements and a segmented cage comprising several rolling elements, wherein the bearing On its two longitudinal sides, the sleeve each has a guide web for laterally guiding the segmented cage, and each guide web is oriented substantially perpendicularly to the raceway of the bearing sleeve. The invention also relates to a disc brake system with such a segmented rolling bearing. Background technique [0002] Segmented rolling bearings and disc brake systems of the type mentioned at the outset are already known. They are used to support the levers in pneumatically operated disc brakes. These segmented rolling bearings also work with low friction under high loads and are necessary to minimize hysteresis in the system. [0003] Thus, EP 2312173 describes such a segmented rolling bearing and an air disc brake device with such a segmented rolli...
