According to an embodiment, a three-section hydraulic mechanical stepless transmission device for a loader includes a casing, a hydraulic speed control circuit, an ahead and astern mechanism, a split-collecting mechanism, a hydraulic section fixed shaft gear transmission system, a first hydraulic mechanical section fixed shaft gear transmission system, a second hydraulic mechanical section fixed shaft gear transmission system, and an output portion. According to another embodiment, the three-section hydraulic mechanical compound stepless transmission device includes a hydraulic circuit which transmits only part of power.

To provide a technique for reliably acquiring a required braking power during travel and for efficiently using a regenerative power generated during braking. A work vehicle calculates a regenerative power outputted from an electric motor and a target hydraulic driving power for driving a hydraulic pump, supplies the regenerative power to the generator motor operating as a motor and makes the generator motor consume the regenerative power in a case where the regenerative power is equal to or smaller than the target hydraulic driving power, and supplies the regenerative power to the generator motor operating as the motor and makes an exhaust brake consume a power equivalent to a difference between the regenerative power and the target hydraulic driving power in a case where the regenerative power is larger than the target hydraulic driving power.

Provided is a loading vehicle in which a control characteristic of traction force can be easily and finely set and changed while a configuration of a hydraulic circuit is simple. An HST traveling driven wheel loader includes an electronically controlled HST pump and HST motor, including a solenoid proportional pressure reducing valve to control displacement volume of the HST pump based on a control signal output from a controller. The controller stores characteristic tables indicating a correlation between discharge pressure of a loading hydraulic pump or an operation state of an engine and a maximum discharge pressure of the HST pump, and when the vehicle speed corresponds to work requiring traction force, outputs a control signal to the solenoid proportional pressure reducing valve so as to obtain the maximum discharge pressure Pm of the HST pump that corresponds to one of the characteristic tables.

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.

Provided is a work machine capable of notifying that maintenance is necessary due to continuation of clogging in a cooling device or decrease in cooling performance. A wheel loader 1 including a radiator 31 and an oil cooler 32 comprises a controller 5, 5A configured to determine a clogging continuation state of the radiator 31 or the oil cooler 32. The controller 5, 5A determines whether clogging is occurring in the radiator 31 or the oil cooler 32 based on outside air temperature AW and cooling water temperature CW or hydraulic oil temperature HW, determines whether the clogging continues based on a clogging occurrence ratio R1, R2 while an engine 30 is operating, and outputs a notification command signal for providing the alarm buzzer 61 and the user management system 62 with a command to notify that maintenance is necessary when it is determined that the clogging continues.

Provided is a loading work vehicle capable of improving work efficiency even when working on a slippery road surface. An HST-traveling-drive wheel loader 1 comprises a step-on amount detection sensor 610, a discharge pressure detection sensor 75, a mode switch device 60, and a controller 5. The controller 5 is configured to: determine whether a limit mode is selected by the mode switch device 60; specify an operation state of the wheel loader 1 when determining that the limit mode is selected; limit maximum traction force to a first set value which is set based on a static friction coefficient μ and vehicle weight when specifying that a bucket 23 is pushed into a natural ground 100; and increase the maximum traction force from the first set value when specifying that excavation of the natural ground 100 is started.

A method for predicating a service life of a fuel filter includes causing a fuel pump of a fuel system to direct fuel through a fuel filter of a fuel system. The method also includes receiving work cycle data from machines that implement a same or similar fuel system. The method further includes receiving, via sensors of the fuel system, fuel system data and determining, from the fuel system data, a pressure difference across the fuel filter. The method further includes determining, based on the work cycle data, predicted load cycle data for the fuel system and determining, via a filter life model, a filter service interval representing an amount of time the fuel filter is operable in the fuel system prior to the pressure difference reaching a predetermined value.

A work vehicle including an articulated vehicle chassis having a front frame portion and a rear frame portion pivotally coupled together at a generally vertical pivot axis. The front frame portion carries a front axle and the rear frame portion carries a rear axle. A steering system includes at least one steering cylinder connected between the front frame portion and the rear frame portion. A power plant provides motive power to the work vehicle, and a transmission receives power from the power plant and provides power to the front axle and rear axle. The work vehicle further includes a secondary clutch interconnected between the transmission and the rear axle. The steering system is configured to disengage the secondary clutch to provide reactive steering, whereby the front frame portion tows the rear frame portion. The rear frame portion freely articulates relative to the front frame portion.

An electric drive arrangement for a drive train of a work machine includes a multi gear transmission. The multi gear transmission includes at least two gears that provide different transmission ratios for various driving modes of the work machine, a multi gear transmission drive, and a multi gear transmission output configured to be mechanically coupled to an axle of the drive train. The electric drive arrangement further includes an electric motor configured to drive a driving movement of the work machine via a shaft that is mechanically coupled to the multi gear transmission drive of the multi gear transmission.
