  • Patent number: 12103401
    Abstract: A braking system for a vehicle at least partially propelled by an electric traction motor electrically connected to an electric power system. The braking system comprises an electric machine configured to be electrically connected to the electric power system, the electric machine comprising a first output shaft and a second output shaft, an air blower controllably connected to the first output shaft by a clutch, the clutch being controllable between an open position in which no power is transmitted from the electric machine to the air blower, and a closed position in which power is transmitted from the electric machine to the air blower, and a fluid pump operatively connected to the electric machine via the second output shaft, wherein the fluid pump is arranged in upstream fluid communication with a fluidly operated member and in downstream fluid communication with a fluid tank.
