Embodiment Construction

[0027] figure 1 A sealing device of a wheel bearing of a motor vehicle, indicated as a whole by the reference numeral 100 , is shown.

[0028] The wheel hub 12 is mounted rotatably on a wheel bearing housing 16 via a rolling bearing 14 in a known manner. The hub part 12 is itself in driving connection with a cardan shaft 18 .

[0029] The sealing device 100 comprises a main seal 110, here designed in the form of a cassette seal, arranged between the bearing device outer ring 14-1 and the bearing device inner ring 14-2, and spaced apart from the main seal 110. A front seal 120 is provided which is arranged between the stationary wheel bearing housing 16 and the rotating cardan shaft 18 .

[0030] like figure 1 It can be further known that the front seal is designed as a centrifugal seal 120 vulcanized on the cardan shaft 18, and the sealing lip 120-1 of the centrifugal seal abuts against the fixed wheel support device housing formed on 16 on the stopper 16-1.

Abstract

The invention relates to a sealing device (100) for a wheel bearing of a motor vehicle, the sealing device having a main seal (110) and a front seal (120) for sealing the The rolling bearing (14) between the main seal (16) and the rotating bearing (18) is sealed, the front seal is spaced apart from the main seal (110) and arranged between the fixed bearing (16) and the rotating bearing (18). between the supports (18). The invention is characterized in that the front seal is designed in the form of a centrifugal seal (120), which is arranged on the rotary support (18), the sealing lip (120‑1) of which It rests against a stop (16-1) formed on the fixed support (16).

Description

technical field [0001] The invention relates to a sealing device for a wheel bearing of a motor vehicle. Background technique [0002] Wheel bearings of motor vehicles usually have one or more main seals which are arranged primarily between the outer ring and the inner ring of the rolling bearing and seal the gap between the outer ring and the inner ring. Primary seals of this type which directly seal against wheel bearings are sufficiently known from the prior art. Reference is made only for example from document DE 10 2013 015 911 A1. [0003] It is known from document DE 196 00 125 A1 to arrange a main seal with a sealing lip relieved by centrifugal force between the inner ring and the outer ring for sealing the rolling bearing. However, the installation space usually available at this point is very narrow, which correspondingly limits the setting parameters of the centrifugal seal. [0004] In order to enhance the sealing effect of the seal of the wheel bearing, it is...
