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.

A vehicle power supply device is provided. The vehicle power supply device includes: a fixed base; a scissor-fork lifting mechanism, where the scissor-fork lifting mechanism is configured to be driven by a drive device to ascend or descend; and the scissor-fork lifting mechanism includes at least one scissor-fork swing rod set, the scissor-fork swing rod set includes at least one pair of swing rods, each pair of swing rods includes two swing rods that are cross-arranged and are hinged with each other, and two swing rods in a pair of swing rods that is closest to the fixed base are separately mounted on the fixed base; and a power supply head, where the power supply head is mounted on two swing rods in a pair of swing rods that is farthest from the fixed base, and the power supply head is driven by the scissor-fork lifting mechanism to ascend or descend.

This rapid descent device comprises a valve comprising two chambers, at least one rub strip fastened to the body of the current-collector bow of the pantograph, intended to come into contact with the overhead wire and equipped with degradation detection circuit, at least one supply line of fluid to the main chamber of the valve, at least one feed line intended to feed this fluid to the pilot chamber of the valve, as well as at least one detection line extending from the pilot chamber of the valve, to feed a respective detection circuit. The rapid descent device comprises means for temporary shut out of the feeding of fluid of the main chamber, which reliably ensures the initial raising of the pantograph until the pantograph comes into contact with the overhead wire.

An energy transfer device is configured for electrically connecting an electrical vehicle to a charging station. The energy transfer device includes a lengthwise link having an upper end and lower end and a crosswise link having an upper end and lower end. The lower ends of the lengthwise link and the crosswise link are configured to be arranged on the electrical vehicle slidably in crosswise direction of the electrical vehicle. The upper end of the crosswise link is connected to the lengthwise link between its ends such that, by sliding the lower ends of the lengthwise link and the crosswise link towards each other, the upper end of the lengthwise link will be moved away from the electrical vehicle for connecting to the charging station.

Said pantograph comprises a chassis, a bow, an articulated arm (210) comprising at least one main rod (216) and at least one auxiliary rod (220), an aileron assembly comprising at least one aileron (10) which is movable relative to the articulated arm, means (3) for supporting the movable aileron (10) which are movably mounted on one of the rods, which is to say either the main rod or the auxiliary rod, which is referred to as the support rod (216), means for immobilizing (4, 7) the support means relative to the support rod, and orienting means (8) which are mounted on the other rod, which is to say either the main rod or the auxiliary rod, which is referred to as the orienting rod (220). Said orienting means are designed such that, over a first range of extension of the articulated arm (210) in which the bow moves between a lower position and an intermediate position, said orienting means do not act on the support means, such that a characteristic angle (α10) of the aileron, which is formed in the vertical plane by the movable aileron and the main axis (A216) of the support rod, is substantially constant; and over a second range of extension of the articulated arm (210) in which the bow (208) moves between the intermediate position and a high position, said orienting means act on the support means, such that the characteristic angle of the aileron varies continuously.

A control system includes an interface device having a body extending between a first end and a second end and that provides power to a vehicle system from an external power source. Sensors may be coupled with the interface device and detect sensor data associated with the coupling of the external power source with the interface device. A controller receives the sensor data from the sensors and determines a coupling location at which the external power source is coupled with the interface device. The coupling location may be at a first position between the first end and the second end of the interface device. The controller controls movement of the vehicle system to change the coupling location between the external power source and the interface device from the first position to a second position between the first and second ends of the body.
