Title: ELECTRICALLY DRIVEN UNDERGROUND VEHICLE, IN PARTICULAR A MOBILE LOADER
Abstract:
The invention relates to an electrically driven mobile underground vehicle, comprising: a chassis having at least two driven drive wheels (22); an electric trailing cable (26) for connection to an electrical supply network; an electric drive motor (42) that is electrically connected to the trailing cable (26) for driving the drive wheels (22); an energy store (28); an auxiliary drive motor (32) followed by a hydraulic fluid transmission; a switchgear assembly (50) and a processor for controlling the supply of the electric drive motor (42) and the electric auxiliary drive motor (32) with electrical energy, wherein the drive motor (42) drives the drive wheels (22) directly while bypassing the hydraulic fluid transmission; the energy provided by the energy store (28) for driving the drive wheels (22) and for temporarily moving the mobile loader (20) independently of the supply network is sufficient. The invention further relates to a method for operating an electrically driven mobile underground vehicle.
