WORK VEHICLE AND CONTROL METHOD FOR WORK VEHICLE
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.
Arrangement and a method for controlling the temperature of air being fed to a vehicle engine
An arrangement for controlling the temperature of air being fed to a vehicle engine includes an engine compartment in which the engine is arranged. The engine compartment is provided with an ambient air intake allowing an airflow into the engine compartment. The engine is provided with an engine air intake arranged inside the engine compartment. The arrangement further includes an air fan for forcing the airflow via the ambient air intake into the inside of the engine compartment. The engine air intake is arranged in a position allowing at least a substantial part of the airflow to enter the engine air intake.
Working machine and a method for operating a working machine
A working machine includes a prime mover for supplying torque to the driving wheels of the working machine, and a transmission line arranged between the prime mover and the driving wheels for transmitting torque from the prime mover to the driving wheels. The transmission line includes a gearbox arranged between the prime mover and the wheels, and the working machine further includes at least one hydraulic machine in a hydraulic system for moving an implement arranged on the working machine and/or steering the working machine, and an electric machine for driving or braking the driving wheels and/or for driving or braking the at least one hydraulic machine. The electric machine is arranged in parallel with the prime mover with respect to the transmission line and is mechanically connected to the transmission line between the prime mover and the gearbox. The gearbox is a continuously variable transmission having a variator unit, and the gearbox has an operation mode where the rotation speed of the output shaft of the gearbox is zero or close to zero independently of the rotation speed of the input shaft of the gearbox at the same time as torque can be transmitted from the input shaft to the output shaft.
TRANSMISSION, AND CONTROL SYSTEM FOR WORK VEHICLE
A second element fixing clutch is switchable between a released state and an engaged state. In the released state, the second element fixing clutch releases a second element of a planetary gear mechanism so that the second element is rotatable. In the engaged state, the second element fixing clutch fixes the second element of the planetary gear mechanism so that the second element is non-rotatable. A transmission is switchable between at least two modes of a first continuously variable transmission mode, a second continuously variable transmission mode, and a direct mode, by the second element fixing clutch being switched between the released state and the engaged state.
WORK VEHICLE AND CONTROL METHOD FOR WORK VEHICLE
A controller determines a target rotation speed of an engine from an operation amount of an accelerator operating member. The controller determines whether a vehicle is in coasting deceleration. The controller decreases a differential pressure between a first circuit and a second circuit of a hydraulic circuit according to a deviation between an actual rotation speed of the engine and the target rotation speed, or the operation amount of the accelerator operating member when the vehicle is in the coasting deceleration.
Work vehicle
A work vehicle includes a vehicle body that includes a heat exchange room in which an opening portion facing a rear side is formed, and a rear passage extending in a width direction along a lower edge portion of the opening portion behind the opening portion, a cooling unit that is provided in the heat exchange room and includes a rear surface facing the rear side, and a blower unit that includes a fan rotationally driven and a movable shroud covering the fan from an outer peripheral side, and that is movable with respect to the vehicle body so that a movement region of the blower unit overlaps the rear passage between a closed position at which the blower unit faces the rear surface of the cooling unit from the rear side and an open position at which the blower unit exposes the rear surface of the cooling unit.
FUEL TANK DRAIN PLUG
Power machine fuel tanks include a plug receptacle and a cover for the plug receptacle which seals the plug receptacle from an interior of the fuel tank. A receptacle insert positioned within the plug receptacle allows a fuel plug to be removably secured to the fuel tank. The cover prevents leakage from inside the fuel tank through the plug receptacle, regardless of whether the plug is secured within the receptacle insert, unless the cover has been removed from a sealing position.
Wheel hub unit
A wheel hub unit is provided including at least one planetary gear set, including a sun gear, one set of planet gears, a carrier, and a ring gear, wherein each of the planet gears of the set of planet gears is provided with an engagement arrangement adapted for engagement with a corresponding engagement arrangement of the ring gear, wherein the engagement is provided at an engagement area in which the engagement arrangement of the planet gears overlap the engagement arrangement of the ring gear, a bearing, including an inner bearing ring, an outer bearing ring and rolling elements, wherein the inner bearing ring constitutes the ring gear of the planetary gear set, and wherein a center of each of the respective rolling elements is axially displaced in relation to the engagement area. A vehicle including such a wheel hub unit is also provided.
Work machine and method for controlling work machine
A work machine includes an engine, a motor-generator, a battery, a power detector, a temperature detector, and circuitry. The engine is to move the work machine. The motor-generator is to move the work machine and to generate electric power. The battery is to store the electric power generated by the motor-generator. The power detector is to detect a charge level of the electric power stored in the battery. The temperature detector is to detect a temperature of the battery. The circuitry is configured to control the motor-generator in accordance with the charge level selectively to move the work machine or to generate electric power when the temperature of the battery detected by the temperature detector is within a temperature range.
MINING MACHINE AND ENERGY STORAGE SYSTEM FOR SAME
A mobile mining machine includes a plurality of traction elements, a plurality of motors, a power source in electrical communication with the plurality of motors, and an energy storage system in electrical communication with the plurality of motors and the power source. Each of the motors is coupled to an associated one of the plurality of traction elements. Each of the motors is driven by the associated traction element in a first mode, and drives the associated traction element in a second mode. The energy storage system includes a shaft, a rotor secured to the shaft, a stator extending around the rotor, and a flywheel coupled to the shaft for rotation therewith. In the first mode, rotation of the motors causes rotation of the flywheel to store kinetic energy. In the second mode, rotation of the rotor and the flywheel discharges kinetic energy to drive the motors.
