ABSTRACT:
A wheel assembly for large off-road mining vehicles wherein an electric motor and drive system for each wheel is combined with a hydrodynamic retarder. The hydrodynamic retarder is mounted such that a rotor is directly connected to an electric motor shaft where typically a disc-type parking brake is mounted. This arrangement eliminates any possible mechanical failure of a gear train or other power reduction or increasing device which would otherwise result in the loss of braking.
