The present invention relates to a support mechanism for a charging cable for electric vehicles. The charging cable comprises, at its distal end, a charging plug connectable to a charging inlet of an electric vehicle. The support mechanism comprises at least one joint and at least one spring element for facilitating movement of the support mechanism at least in vertical dimension between an idle position and an operation position. In the idle position, the entire support mechanism and the charging plug are placed above a space reserved for parking the electric vehicles. In the operation position, the charging plug is provided within the space reserved for the electric vehicles during charging, and the charging plug is approximately at the same horizontal level as the charging inlet of an electric vehicle.

A rotating current collector includes a current collecting unit, an electrode unit, an upper gear unit and a lower gear unit. The current collecting unit makes contact with an overhead contact line. The electrode unit is connected to a lower portion of the current collecting unit. The upper gear unit is fixed to a lower portion of the electrode unit and has an upper gear. The lower gear unit has a lower gear meshing with the upper gear. The current collecting unit rotates in one direction as the upper gear and the lower gear mesh with each other.

A road-guided motor vehicle includes a power collector for an overhead line and an actuator arrangement. The power collector is controlled by the actuator arrangement from a first, pantograph-lowered into a second, pantograph-raised position or vice versa. The power collector is assigned a sensor arrangement having a data connection to a control unit of the actuator arrangement. The control unit is configured such that a contact pressure of power collector against overhead line is detected or determined using sensor arrangement data, a memory with spatially resolved contact pressures for the power collector and a position ascertaining unit. At a motor vehicle position determined by the position ascertaining unit, an associated contact pressure is read out from the memory and automatically set by the control unit or signaled to a motor vehicle driver. A method for raising a power collector pantograph onto an overhead line is also provided.
