An active track-chain sag management system for usage in conjunction with crawler vehicles having tracked undercarriages includes a movable track-engaging member positioned for physical engagement into a track-chain of the tracked undercarriage, an electric drive assembly controllable to adjust a track-tensioning position of the movable track-engaging member relative to the track-chain, and a controller operatively coupled to the electric drive assembly. The controller is configured to command the electric drive assembly to repeatedly adjust the track-chain sag of the track-chain by varying the track-tensioning position of the movable track-engaging member during operation of the tracked undercarriage.

A sensor data processing and control system acquires data from multiple, disparate sources on a worksite. A plurality of different data pipes are generated for different action systems. The action systems receive data through a corresponding data pipe and generate action signals, based upon aggregated and fused data received through the data pipe.

Control and mapping based on multi-vehicle sensor fusion

A rotary heat exchanger includes a hub configured to be rotatably driven by a shaft, a fan including a plurality of fan blades integrally coupled to the hub and extending radially outwardly therefrom, and a heat exchanger including a plurality of heat exchanger sections. The heat exchanger includes a plurality of cooling fins for receiving air from the fan. Each of the plurality of heat exchanger sections is located between two of the plurality of fan blades. The hub, the fan, and the heat exchanger are integrally formed as a single body by a three-dimensional printing process.

Rotary heat exchanger and system thereof

A powered axle for a work vehicle with a dual wheel arrangement includes an axle housing, an axle hub mounted to the axle housing, and an output hub having opposite axial ends supported by one or more wheel bearings for rotation about the axle hub along a rotation axis. An electric drive is disposed, at least in part, within the axle housing, and a hub gear set is disposed, at least in part, within the axle hub and configured to transmit power from the electric drive to the output hub for rotation of the dual wheel arrangement. A wheel brake disposed radially between the axle hub and the output hub and axially between the ends of the output hub is configured to selectively permit and arrest rotation of the output hub.

Powered axle for dual wheel work vehicle

An axle cooling system for a vehicle that has a first axle hydraulic circuit that passes through a first axle assembly, a second axle hydraulic circuit that passes through a second axle assembly, a first pump that circulates axle oil through the first axle hydraulic circuit, a second pump that circulates axle oil through the second axle hydraulic circuit, a first temperature sensor that monitors a first axle temperature of the first axle assembly, and a second temperature sensor that monitors a second axle temperature of the second axle assembly. The first pump and the second pump are independently controlled from one another to circulate axle oil through the corresponding first or second axle hydraulic circuit.

A power shift transmission includes an input shaft and a gear housing including a gear assembly disposed therein. The gear assembly is driven by the input shaft. The transmission also includes an output shaft rotated by the gear assembly. The transmission also includes an auxiliary shaft extending through a portion of the gear housing. The auxiliary shaft is rotated by an internal combustion engine. The transmission also includes a clutch assembly movable from a disengaged position to an engaged position. The clutch assembly includes a first clutch portion coupled to the input shaft and a second clutch portion coupled to the auxiliary shaft. The second clutch portion transmits rotational force to the first clutch portion only with the clutch assembly in the engaged position. The transmission also includes an electric motor including an electric motor shaft in geared relationship with the first clutch portion.

A pattern recognition system receives an image captured by an image capture device, of an operator and the operator is identified. Operator information is accessed, based upon the identified operator, and a control signal is generated to control a mobile machine, based upon the operator information.

Machine control using biometric recognition

A rotational drive unit having an input rotatable about a first axis of rotation and configured to be driven by a power source in a single rotational direction. The rotational drive unit including a first shaft in operable communication with the input and configured to rotate in a first direction, a second shaft in operable communication with the input and configured to rotate in a second direction opposite the first direction, an output rotatable about a second axis of rotation, and a clutch assembly in operable communication with the first shaft, the second shaft, and the output. Where the clutch assembly is operable in a first configuration in which force is transmitted between the first shaft and the output, and a second configuration in which force is transmitted between the second shaft and the output.

An electric drive system for mechanical machinery. The electric drive system includes a first electrical bus and a second electrical bus each configured to operate at different voltages. A first generator is configured to provide electric current to the first electrical bus at a first voltage. A second generator is configured to provide electric current to the second electrical bus at a second voltage that is different from the first voltage. A first electric motor is coupled to the first electrical bus and configured to operate on electrical power from the first electrical bus at the first voltage. A second electric motor is coupled to the second electrical bus and configured to operate on electrical power from the second electrical bus at the second voltage. Mechanical power used to drive the mechanical machinery is generated by both the first electric motor and the second electric motor.

A power train and related vehicle have a multi-mode power transmission with a first continuously variable power source ('CVP') that may convert rotational power received by the engine for transmission to a second CVP. A variator assembly may receive rotational power from the second CVP at a first input and directly from the engine at a second input. A control assembly may include one or more output components and a plurality of clutch devices arranged between the one or more output components and the variator assembly and engine. In a first state of the control assembly, the plurality of clutch devices may collectively provide direct power transmission between the engine and the one or more output components. In a second state of the control assembly, the plurality of clutches may collectively provide power transmission between the variator and the one or more output components.

A power train and related vehicle provides multi-mode power transmission. A first continuously variable power source ('CVP') may convert rotational power received by the engine for transmission to a second CVP. A variator assembly may receive rotational power from the second CVP at a first input and directly from the engine at a second input. A control assembly may allow the power train to shift between multiple modes, such as a series mode, a split-path mode, and a direct mode. The control assembly may provide seamless shifting between at least two of these modes.
