A SYSTEM AND A METHOD FOR USE IN CONNECTION WITH A WHEEL TORQUE GENERATING COMPONENT IN A HEAVY-DUTY VEHICLE

The invention relates to a system (10a) for use in connection with a wheel torque generating component (20) in a heavy-duty vehicle (1). The system comprises a fluid conduit (26), a compressor (22) configured to provide a pressurized air flow trough said fluid conduit, a mass flow adding arrangement (28) configured to add a fluid to the pressurized air flow in the fluid conduit, thereby increasing the mass flow of the pressurized air flow, and a flow directing device (32) arranged downstream of the mass flow adding arrangement and configured to direct the pressurized air flow, including the added fluid, from the fluid conduit to the wheel torque generating component so as to control the temperature of the wheel torque generating component. The invention also relates to a method for use in connection with a wheel torque generating component in a heavy-duty vehicle.
