摘要： 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.

摘要： A drive arrangement for displacing a contacting device from a raised position to a lowered position includes a four-joint linkage having first, second and third arms interconnected such as to displace the contacting device as the first, second and third arms pivot. An actuator is connected via an actuating lever to the first arm and acted upon by a spring force which counteracts an actuating force applied by the actuator on the actuating lever. The actuating lever is pivotally connected to the first arm and supportable on the first arm via a catch when the first arm is displaced into a raised position and detachable from the first arm when the first arm is displaced into a lowered position, so that the actuating lever assumes a release position in the lowered position of the contacting device, with the contacting device maintained in the lowered position by its weight force.

摘要： A non-rail-bound vehicle, in particular a truck, includes a current collector for supplying electric energy from a two-pole overhead conductor. A rocker can be vertically lifted or lowered by a rocking movement of a support extension arm about horizontal tilting axes of lower hinge assemblies and can be laterally displaced by a tilting movement of a support extension arm about vertical pivot axes of the lower hinge assemblies. The lower hinge assemblies are supported on a lifting device which is connected to a vehicle frame of the vehicle and through which the current collector can be vertically moved between a lower parked position and an upper operating position. In this manner, overhead conductors with an extended height range can be contacted without the current collector influencing the entire length of the vehicle.

摘要： An electric drive dump truck travels by contacting, with trolley lines, power collection units configured to be moved up and down by lifting devices and receiving electrical power from the trolley lines. A position detection device is configured to detect a position of the electric drive dump truck; a vehicle speed detection device is configured to detect a vehicle speed of the electric drive dump truck; and a storage section is configured to store a position of the trolley lines and a time (hereinafter referred to as a moving-up time) until the power collection units contact with the trolley lines since the power collection units start moving up. A control device is configured to output a signal indicating that the power collection units can be moved up based on the position and vehicle speed of the electric drive dump truck, the position of the trolley lines, and the moving-up time.

摘要： 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.

摘要： A current collector (15) is provided for transmitting energy between a contact wire (2) and a motor coach. The current collector comprises at least one collector shoe (1) and a support arm (11) constructed and arranged to lift the collector shoe, and to apply a contact force in which the collector shoe lies below and against the contact wire. The support arm is rotatably connected to the motor coach about a horizontal axis (17) and raiseable about the axis by a lifting device (3). The lifting device includes a fast actuator (23) which is constructed and arranged to be controlled by a control device (22) in dependence on a signal (20, 21) of at least one displacement sensor, force sensor (18), or acceleration sensor (19) located on the current collector to maintain the contact force of the collector shoe against the contact wire.

摘要： 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.
