Cooling device for arrangement in or at wheel hub motor of motor car for cooling electric power train, has fan supplying cooling air to power train, and centrifugal separator separating particles from cooling air
The device (1) has a fan (2) supplying cooling air to an electric power train of a motor car. A centrifugal separator (3) separates undesired particles (7) e.g. dirt particles, from the cooling air. The separator comprises a tangential inlet region (4), a cone-shaped separation section and/or a collecting container (6) for separating the particles. The container comprises a closable aperture and a paper filter. The container is formed as a plastic injection molded part. The separator comprises magnets and/or magnetic particles, which are arranged in or on a wall of the separator. An independent claim is also included for a motor car comprising a wheel hub motor.
