Abstract: A pantograph assembly for a vehicle includes a linkage configured to be mounted to the vehicle and movable relative to the vehicle between a stowed position and a deployed position. A current-collecting rail is supported by the linkage. The current-collecting rail includes a first end, a second end opposite the first end, a top surface extending between the first end and the second end, and a bottom surface. The current-collecting rail is configured to slidingly contact an overhead wire when the linkage is in the deployed position, and wherein the current-collecting rail is spaced apart from the overhead wire when the linkage is in the stowed position. An end adapter is attached to one of the first end and the second end of the current-collecting rail. A sensor assembly is mounted to the end adapter and configured to detect a distance from the overhead wire.

Abstract: A trolley auto-guided steering is provided to maintain pantographs centered under the power lines, allowing it to achieve higher speeds on grade and reduce wear on a pantograph shoe and/or a carbon brush by moving the contact area within the acceptable constraint limits. The pantograph includes a linkage configured to be mounted to the vehicle and movable relative to the vehicle between a stowed position and a deployed position. A current-collecting rail is supported by the linkage. A sensor assembly is mounted to the pantograph assembly and configured to detect a distance from the overhead wire. Data from the sensor assembly allows for continuous dynamic variable steering toward an aim point determined based on vehicle speed. This helps maintain the work vehicle's position underneath the overhead trolley lines and reduces operator fatigue.

Abstract: A work vehicle includes a pantograph assembly disposed above a cab where an operator rides, a sensor assembly mounted to the pantograph, a control module that includes a guidance system, and steering control system. A visual display is provided in the cab and is configured to display visual indicia of the position of the work vehicle relative to trolley wires by a plurality of lights based on the data received from the sensor assembly. By the steering control system manually or automatically, the pantograph assembly is able to align with the trolley lines so that electric power can be supplied to the work vehicle.

Abstract: An internal combustion engine includes a plurality of combustion cylinders, at least one turbocharger, an exhaust gas line and an exhaust gas recirculation system. A compressor bypass may fluidly connect a compressed air line to the exhaust gas line. If the internal combustion engine has dual cylinder banks, an exhaust gas balance tube may extend between exhaust gas lines of the cylinder banks. A wastegate may fluidly connect the exhaust gas balance tube to an exhaust gas outlet. A compressor bypass may fluidly connect the compressed air line to the exhaust gas balance tube.
