Abstract

A wheel bearing assembly includes a wheel hub which is mounted on an axle element by at least one wheel bearing, and a temperature-measuring device, visible from outside the wheel bearing assembly, configured to measure and display the exceeding of a limit temperature in the wheel bearing, wherein the temperature-measuring device comprises at least two separate temperature-measuring elements, each of which is connected to the wheel bearing in a heat-conducting manner along a heat-conducting path and undergoes a visually identifiable change at a predetermined trigger temperature. The at least two temperature-measuring elements are disposed in such a way that, when the wheel bearing heats up, the elements heat up at different rates, and/or the temperature-measuring elements have different trigger temperatures.
