Embodiment Construction

[0034] In the following description, identical or functionally equivalent elements are denoted by the same reference numerals.

[0035] figure 1 A bearing assembly 100 is shown. Bearing assembly 100 may be a wheel bearing assembly for a motor vehicle. exist figure 1 In the exemplary embodiment shown, the bearing assembly comprises two bearings, each bearing comprising a first bearing ring 1 and a second bearing ring 2 arranged rotatably relative to each other. The (both) bearings are arranged on an axle 5 and each bearing comprises (located) a rolling body 3 between the first bearing ring 1 and the second bearing ring 2 . Lubricant 4 is provided in a sealed space that may be referred to as inside the bearing, including around the axle 5 and around the bearing (comprising the first bearing ring 1, the second bearing ring 2 and the rolling elements 3) ( around) area. Said lubricant is sealed with respect to the exterior by a housing 9 and a hub cover 8 which at least partia...

Abstract

A wheel bearing assembly for a motor vehicle includes a housing having an interior, at least one bearing in the interior including a first bearing ring and a second bearing ring rotatably disposed relative to the first bearing ring, a plurality of rolling elements disposed between the first bearing ring and the second bearing ring, a lubricant in the housing interior in contact with at least a part of the at least one bearing, an axle connected to the at least one bearing, a sensor in the housing interior in contact with the lubricant, the sensor being configured to sense at least one propertyof the lubricant and to output a signal indicative of the at least one property of the lubricant, and a display unit outside the housing interior and in communication with the sensor, the display unit being configured to produce an output based on the signal.

Description

technical field [0001] The present disclosure relates to a bearing assembly, in particular a wheel bearing assembly for a motor vehicle, comprising at least one bearing and an axle within a housing containing a lubricant. Background technique [0002] The bearing assembly is frequently lubricated with oil or other suitable lubricant to ensure its optimal functioning. However, for some applications, the lubricant used must be monitored regularly and changed or replaced if necessary. A change ( / replacement) may be necessary eg if the lubricant breaks down or becomes contaminated with dirt or metal particles etc. Especially in the case of wheel bearing assemblies, especially for trucks, determining the condition of the lubricant is expensive because the hubcap has to be removed in order to access the lubricant. In some cases, a hubcap (also referred to as a hubcap) may be firmly connected to the hub, eg by screws. This is the case, for example, when the lubricant is located ...
