Housing for a rolling-element bearing and drive-train segment for a vehicle having the housing

Abstract

A shaft bearing assembly including a housing, in which a bearing is arranged, is disclosed. The housing includes a first and second flange part. The first and second flange parts can be connected to each other, wherein the two flange parts jointly form a receptacle for the rolling-element bearing, wherein one of the flange parts has at least one securing interface and the other has at least one securing counter-interface, wherein the first and second flange parts can be connected to each other and/or fixed to each other in a positive-locking manner by the securing interface and the securing counter-interface that prevents the two flange parts from detaching from each other in an axial direction established by projecting the axis of rotation of the rolling-element bearing onto the housing. The first and second flange parts are hooked to each other by the securing interface and the securing counter-interface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) As shown in FIG. 1, a drive train portion 100 for a vehicle having a gearbox 101, a connection shaft 102, at least one joint 106, an additional connection shaft 103 and having a shaft bearing arrangement 1 for the connection shaft 102 is shown. The shaft bearing arrangement 1 is arranged in a stationary manner with respect to the gearbox 101, and the connection shaft 102 extends from the gearbox to the joint 106 and is supported in the shaft bearing arrangement 1.

(14) As shown in FIGS. 2, 3, 4A and 4B, in one embodiment the shaft bearing arrangement (comprises a housing 10 in which a roller bearing 104 can be arranged. The housing 10 comprises a first flange portion 2 and a second flange portion 3. The first and second flange portions 2; 3 can be connected to each other, and the two flange portions 2; 3 together form a receiving member 5 for the roller bearing 104.

(15) One of the flange portions 2; 3 has at least one securing interface 7 and the other has at least one securing counter-interface 8. The first and second flange portions 2; 3 can be connected to each other and/or can be fixed to each other in a positive-locking manner by the securing interface 7 and the securing counter-interface 8, and the positive-locking connection prevents the two flange portions from becoming disengaged from each other in an axial projection direction with respect to the rotation axis of the roller bearing 104 on the housing 10.

(16) The first and second flange portions 2; 3 can be hooked, locked and/or clip-fitted to each other by the securing interface 7 and the securing counter-interface 8.

(17) The housing 10 comprises a plastics material and/or is formed therefrom.

(18) The securing interface 7 is formed on and/or integrated in one of the flange portions 2; 3 and the securing counter-interface 8 is formed on and/or integrated in the other flange portion 2; 3. See FIGS. 2-9B.

(19) The first flange portion 2 has a first receiving portion 51 and the second flange portion has a second receiving portion 53, as shown in FIGS. 3 and 6. The first and second receiving portions 51; 53 complement each other when the two flange portions 2; 3 are connected and together form the receiving member 5 for the roller bearing 104.

(20) The roller bearing 104 is arranged in a rotatable and/or pivotable manner in the receiving member 5.

(21) The first and/or second receiving portion 51; 53 has/have at least partially and/or in regions a spherical and/or crown-like receiving contour 52; 54, as shown in FIGS. 3 and 6, so that the receiving member 5 in the connected state of the two flange portions 2; 3 has a spherical and/or crown-like overall receiving contour.

(22) The housing 10 has a standing base 4, and the standing base 4 has at least one aperture and/or at least one recess 6 for introducing a securing element. The securing element is constructed to secure the housing 10 to a surrounding construction 9.

(23) As shown in FIGS. 2, 3, 4A and 4B, only one of the flange portions 2; 3 may include the standing base 4.

(24) Alternatively, as shown in FIGS. 5, 6, 7A and 7B, the standing base 4 can be constructed in two parts and has a first standing base portion 41 and a second standing base portion 42, and the first flange portion 2 comprises the first standing base portion 41 and the second flange portion 3 comprises the second standing base portion. The two standing base portions 41; 42 in the connected state of the flange portions 2; 3 are assembled to form the standing base 4.
