Disclosed is a device for estimating a load in a bearing, including a receiving unit for receiving a sensor signal waveform. The sensor signal waveform is provided by at least one sensor probe arranged at the bearing. The at least one sensor probe is configured to measure a displacement and/or strain of the bearing. The sensor signal waveform is a product of a carrier waveform and a load waveform, and an electronic control unit configured for processing the received measured sensor signal waveform, by determining a rolling element frequency from the measured sensor signal waveform, determining the carrier waveform based on the determined rolling element frequency and the measured sensor signal waveform, determining the load waveform based on determined carrier waveform and the measured sensor signal waveform, and estimating the load in the bearing from the determined load waveform.

A hub assembly includes an inner rotatable hub having inboard and outboard axial ends, a radial flange extending outwardly from the outboard axial end and connectable with the wheel, an inner circumferential surface, and an opposing outer circumferential surface providing inboard and outboard inner races. An outer hub is disposed about the inner hub, connectable with the chassis and has inboard and outboard axial ends, an outer circumferential surface and an inner circumferential surface. The inner surface provides inboard and outboard outer races and a central surface section extending between the two outer races. First and second sets of rolling elements are disposed between the inner and outer races. One or more sensors are each disposed on the central surface section of the outer hub and are each configured to sense strain within the outer hub generated by the rolling elements.
