A work vehicle includes: an engine; a hydraulic pump that is driven by the engine; hydraulic cylinders that are extended and contracted by pressurized fluid delivered from the hydraulic pump; a work device that is moved according to the extension/contraction operations of the hydraulic cylinders; a travel device that is driven independently of the work device; an electrically driven motor that is driven by electric power generated by the engine to operate the travel device; and a controller that controls the hydraulic cylinders and the electrically driven motor. The controller controls the output power of the hydraulic pump and the output power of the electrically driven motor by changing the distribution ratios of a first torque consumed by the work device and a second torque consumed by the travel device among torques output by the engine, on the basis of a reaction force received by the vehicle body.

An integrated hybrid energy recovery and storage system for recovering and storing energy from multiple energy sources is disclosed. The system includes an accumulator unit having a high pressure accumulator and a low pressure accumulator. At least one piston is mounted for reciprocation in the high pressure accumulator. The accumulator unit is configured to receive, store, and transfer energy from the hydraulic fluid to the energy storage media. The system further includes two or more rotational directional control valves, in which at least one rotational directional control valve is positioned on each side of the accumulator unit. Each rotational directional control valve includes multiple ports. The system also includes two or more variable displacement hydraulic rotational units. At least one variable displacement hydraulic rotational unit is positioned adjacent each of the rotational directional control valves.

Disclosed embodiments include power machines having doors with a display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., allowing the operator of the machine to see the displayed information closer to the line of sight with the work area.

A control method for a work vehicle, includes: acquiring a signal for changing a state of a traveling device, to which power is transmitted via a transmission and a clutch, between forward, neutral, and reverse states; outputting a command for reducing a torque of an output shaft connected to the traveling device in a state where a first clutch is engaged, before a specified time elapses from a time point at which the signal for changing to the neutral state is acquired in a state where the first clutch is engaged; outputting a command for releasing the first clutch after the specified time elapses; and outputting a command for controlling the transmission so that a rotation speed of an input-side element of a second clutch to be engaged next coincides with that of an output-side element of the second clutch in a state where the first clutch is released.

A working machine includes a machine body having a front-rear direction and a right-left direction perpendicular to the front-rear direction and having a rear part in the front-rear direction, a right side, and a left side opposite to the right side in the right-left direction. A boom has a front end part and a rear end part opposite to the front end part of the boom in the front-rear direction. The rear end part of the boom is rotatably supported at the rear part of the machine body. The front end part of the boom is to be connected to a working tool. An engine is mounted in the rear part of the machine body. A urea aqueous solution tank is provided on one side of the engine in the right-left direction and a rear side of the engine in the front-rear direction to store a urea aqueous solution.

A single chain drive is disclosed that includes a drive sprocket, a drive motor, idler sprockets, front and rear axle sprockets, and a single chain. The drive motor rotates the drive sprocket, which rotates the idler sprockets, which rotate the single chain, which rotates the front and rear axle sprockets. The drive sprocket can be a lantern gear with covers, and pins that connect the cover, and the idler sprockets can have teeth that mesh with the pins between the covers of the drive sprocket. A drive shaft can couple the drive motor and drive sprocket, and an integrated parking brake can prevent rotation of the drive shaft when engaged. A chain case with lubricant can enclose the drive sprocket, idler sprockets, chain, and axle sprockets. The drive sprocket, idler sprockets and axle sprockets can be sized to provide a desired gear reduction.

The controller determines whether the vehicle is in a shuttle motion from the operating position of the forward/reverse travel operating member and the actual traveling direction of the vehicle. The controller determines a target braking force when the vehicle is in the shuttle motion. The controller determines at least one of a target displacement of the travel pump and a target displacement of the travel motor based on the target braking force.
