  • Mobile machine with an electric traction motor of a traction drive, an electric pump motor of a hydraulic work system, and fluid cooling
    Patent number: 7565943
    Abstract: A mobile machine, such as an industrial truck, has heat-emitting drive components (K) of a traction drive and a hydraulic work system. The traction drive includes at least one electric traction motor (3) and a traction motor control system (7). The hydraulic work system includes at least one electric pump motor (5) and a pump motor control system (6). At least some of the drive components (K) are located in a cooling circuit. The cooling circuit has a cooling device (1), to which, on the output side, the traction motor (3), the pump motor (5), the traction motor control (7), and the pump motor control system (6) are connected, and which can be connected on the input side, depending on the fluid temperature in a reservoir (9) of the hydraulic work system, to the reservoir (9) or to a return line of the heat-emitting drive components (K).
