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.

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.

Drag Detection is provided. A system includes one or more processors of a vehicle, coupled with memory. The one or more processors can determine, for a vehicle, rolling drag based on energy input to one or more motors of the vehicle and a speed of the vehicle. The one or more processors can select, based on the rolling drag and a friction level associated with a surface on which the vehicle traverses, a slip target for the vehicle. The one or more processors can provide the slip target to a traction control system of the vehicle to control the one or more motors.

The invention relates to a device for fastening a sliding element to a current collector or to a rocker mounted thereto, to draw electrical energy from an overhead contact line to an electrically driven vehicle. The device comprises a sliding element, a carrier, a carbon contact piece arranged on the carrier, and a fastening point for fastening the sliding element to the current collector is formed between the sliding element and the current collector. At each fastening point between the sliding element and the current collector, a detent assembly is arranged on the side of the sliding element and, for each detent assembly, a receptacle for the detent assembly is arranged on the side of the current collector. Each detent assembly and the receptacle associated therewith are releasably brought into engagement with each other by inserting and locking the detent assembly in the receptacle.

In a power conversion device, a distance between an output terminal of a first switching module and a cathode terminal of a first diode module in a first direction is arranged to be substantially equal to a distance between an output terminal of a second switching module and an anode terminal of a second diode module in the first direction.

An overhead wire mutual separating situation measuring apparatus detects separation of overhead wires with high accuracy in a manner that the overhead wires are placed with a predetermined amount of deviation. A light projecting unit irradiates overhead wires above a railway with a measuring light spreading in a strip shape in the width direction of the railway. Light receiving units receive light reflected by all or a portion of the overhead wires from the measuring light to output a measurement signal indicative of a contour of the overhead wires. Each light receiving unit mutually partially overlaps a measurement area such that the overhead wires within a predetermined measurement area fall within the measurement visual area of at least one light receiving unit. The processing device processes the measurement signal from each light receiving unit to detect a mutual separation of the overhead wires and the positional deviation thereof.

The present disclosure relates to a novel high-performance repairable sliding plate of a pantograph of an electric locomotive and a manufacturing method thereof. The sliding plate includes a monometallic substrate and a conductive, wear-resistant, anticorrosion and self-lubricating coating integrated with the substrate. The coating is formed by plasma spraying CuTiO.sub.2 core-shell composite powder on the monometallic substrate directly, and includes the following components by mass percent: 60-70% of Ti.sub.4O.sub.7, 15-25% of Cu, 10-15% of Ti.sub.xO.sub.(2x1) and 5-10% of TiO.sub.2, where 5x10. The multifunctional composite coating is the working layer of the sliding plate of the present disclosure, and the damage of the coating can be repaired by plasma spraying with the composite powder, thereby recovering dimensional accuracy and service performance.
