Problems solved by technology

[0008] However, such a design is often impossible or difficult to implement due to the narrow positional relationship and possible undesired interactions with the bearing element or other elements of the system comprising the bearing

Embodiment Construction

[0050] The same reference numerals denote the same or similar elements in the following description of the accompanying figures. In addition, summative reference numerals are used to designate elements and objects which appear several times in one exemplary embodiment or in one illustration, but describe one or more features together. Elements or objects described with the same or general reference signs may be the same in one, more or all features, such as their dimensions, but may also be designed differently if necessary, as long as the description does not other clarifications or explanations.

[0051] As briefly stated at the outset, in many designs in the field of machinery, plant and vehicle construction there is the challenge that when supporting parts and elements that move relative to each other, the same support is achieved by means of bearings, for example due to the presence of The work and / or environmental conditions are sealed to carry out the work. An example...

Abstract

The volume balancing component (400) according to an embodiment includes a housing (410) designed to be fixed on the bearing ring (120), a sealing component (430) that seals the internal volume (440) of the housing (410) The first partial volume (470) is sealed against the second partial volume (480) of the inner volume (440) of the housing (410), located in the opening (490) in the housing (410), which is arranged and designed to allow The first partial volume (470) is fluidically accessible, and a further opening (500) is arranged and designed to enable the second partial volume (480) to be fluidically accessible and to enable fluidic communication with the pressure reservoir. Technology is connected. The housing (410) and the sealing component (430) are designed to cause a volume change of the second partial volume (480) when the first partial volume (470) undergoes a pressure change and / or a volume change. Using this embodiment, it may be necessary, for example, to achieve a better compromise between higher operating reliability of the bearing ( 100 ), smaller installation space requirements and easier implementation of the concept.

Description

technical field [0001] Embodiments relate to a volume balancing element, a bearing and a method for reducing pressure changes in a bearing when operating parameters of the bearing change. Such a bearing can be, for example, a motor vehicle bearing, for example a wheel bearing or a wheel bearing unit of a motor vehicle. Background technique [0002] In many areas of machine, plant and vehicle construction there is the technical challenge of relative guidance of mutually moving components or objects. There should be as low friction as possible, ideally even frictionless movement of the participating elements or objects with respect to each other in one direction of movement, whereas in a direction of movement different from this direction it should be possible to transfer forces from one of the A component or object is passed to another component or object. Such guidance can be realized, for example, by means of bearings. With bearings for rotary motion, for example, low-fr...
