Wheel hub bearing module for a suspension upright or knuckle

A hub bearing module for a lightweight suspension upright or knuckle of a vehicle, the hub bearing module comprising:

• a wheel bearing, and
• a bearing connection interface for connecting the wheel bearing to the suspension upright or knuckle, the bearing connection interface being arranged coaxial with the rolling bearing and including a first sleeve element;
• wherein
• the bearing connection interface further comprises a second sleeve element arranged radially outside the first sleeve element and comprising an annular body having a radially outer lateral surface and a radially inner lateral surface and made of a composite material including reinforcing fibers dispersed in a polymer matrix, and wherein
• the individual reinforcing fibers form groups of fibers aligned with respect to each other, and the groups are uniformly dispersed randomly in the polymer matrix, in order to give rise to a nearly isotropic material, the composite material being preferably selected from the group consisting of BMC (Bulk Molding Compound), LFT (Long Fiber Thermoplastic) and DLFT (Direct Long Fiber Thermoplastic);
• and
• the radially inner lateral surface being mechanically coupled to the first sleeve element and the radially outer lateral surface being configured to mechanically and chemically couple with the suspension upright or knuckle.
