Embodiment Construction

[0032] figure 1 A bearing cap according to the invention is shown in . The bearing cap is used to isolate the bearing inner area from the surrounding environment. The bearing cover comprises an annular edge section 1 spaced apart from the bearing axis X, here in particular concentric with the bearing axis X, which can be seated sealingly in a connection region of the bearing bracket not shown in detail here superior. Furthermore, the bearing cap comprises a cap section 2 which extends in the region surrounded by the annular edge section 1 and is connected to the annular edge section 1 .

[0033] The bearing cover is equipped with a membrane element 3 embodied as a gas-permeable membrane, which enables a pressure equalization between the inner area of ​​the bearing and the surrounding environment. The membrane element is arranged on the opening section 4 . In the cover section 2 , the opening section 4 is formed at a point radially offset from the bearing axis X in the dire...

Abstract

The invention concerns a bearing cover for separating the inner region of a bearing from the environment. The bearing cover according to the invention comprises: an annular edge section (1) which is at spacing from a bearing axis (X) and can be mounted in sealing manner on a connection region; a cover section (2) which extends in a region surrounded by the annular edge section and adjoins the latter; and a membrane element (3) which is designed as a gas-permeable membrane and enables pressure to be equalized between the bearing inner region and the environment. According to the invention, an opening section (4) is formed in the cover section at a location offset radially from the bearing axis and towards the annular edge, and the membrane element is disposed in this opening section which is radially offset from the bearing axis.

Description

technical field [0001] The invention relates to a bearing cover, in particular in the form of an ABS sensor cover, which is itself arranged in the region of the wheel bearing and which, on the one hand, covers the multipole ring which rotates with the wheel hub side when the vehicle is running, and on the other hand An aspect has a sensor that detects the alternating magnetic field emitted by the multipole ring. Background technique [0002] Bearing arrangements, in particular wheel bearing arrangements, are widely implemented as permanently lubricated rolling bearing arrangements. The sealing of such permanently lubricated rolling-element bearing arrangements is usually achieved by an elastic sealing ring, optionally forming a plurality of sealing lips, which is arranged in the immediate vicinity of the rolling-element track region. Furthermore, the sealing ring can be covered by a disk-shaped or annular cover in order to prevent dirt and moisture from entering the sealing...
