A motor vehicle has a control device, a first sensor and a global positioning device. The control device has a control unit and a data memory. At least one item of information about an arrangement of an overhead line is stored on the data memory. The control unit is connected to the first sensor and to the global positioning device. The first sensor determines a position of the overhead line relative to the motor vehicle and provides the control unit with the relative position. The global positioning device determines a global position of the motor vehicle and provides the control unit with it. The control unit, on the basis of the established relative position, the established global position and the information about the arrangement of the overhead line, calculates a position of the motor vehicle.

A method for monitoring a pantograph. The method includes acquiring an impulse response of the pantograph, extracting a natural frequency and a damping coefficient of the pantograph from the impulse response, obtaining a similarity factor of a plurality of similarity factors, and detecting a fault in the pantograph from the plurality of fault types based on the plurality of the similarity factors. Acquiring an impulse response of the pantograph includes generating the impulse response by tapping the head of the pantograph and recording the impulse response utilizing a recording equipment.

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 current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

A current collector for a non-rail-bound, electric traction vehicle has an articulated support linkage, which, on the contact wire side, supports rocker assemblies with contact strips and, on the vehicle side, has a base joint for articulation to the traction vehicle. A pneumatic reciprocating drive is coupled to the support linkage for raising the rocker assemblies from a lower parking position into an upper contact position when the reciprocating drive is pressurized and for lowering into the parking position under its own weight when depressurization occurs. An exhaust air line connects the reciprocating drive to the environment to lower the rocker assemblies. An air accumulator and a downstream throttle valve are connected between the reciprocating drive and an environment opening of the exhaust air line. The rocker assemblies can be quickly lowered and nevertheless brought into the parking position without damage in order to disengage the current collector.

A train includes: a body, a pantagraph current collector and an ice scraper, wherein the pantagraph current collector is provided on the body; and the ice scraper is mounted on the pantagraph current collector, and the ice scraper is in contact with a power supply rail, so as to remove ice on the power supply rail during the movement of the body. Thus, it is ensured that the pantagraph current collector can be in effective contact with the power supply rail during the running of the train, and normal power supply of the train is ensured. The problem in the conventional art in which the current receiving performance of a current receiver of a train is greatly reduced when a power supply rail is frozen or suffers from heavy snow is solved.
