A method for operating a drive train for a mobile machine, including a first electric motor driving a working drive of the mobile machine via a first transmission arrangement, and a second electric motor driving a propulsion drive of the mobile machine via a second transmission arrangement, wherein a rotational speed of the second electric motor increases during a shifting operation of the second transmission arrangement out of a higher gear stage into a lower gear stage, and wherein during the shifting operation, a drive connection is established via a first clutch between the first electric motor and the propulsion drive, such that the propulsion drive is driven by the first electric motor during the shifting operation.

A drive axle for a work machine for driving wheels that are coupled to the drive axle. The drive axle includes a spur gear stage with an input shaft. A differential gear unit couples to the spur gear stage and to the wheels via wheel drive shafts. The drive axle further includes a reduction gear unit with an output element couples to the input shaft of the spur gear stage—and an input element which couples to an output shaft of an electric drive machine.

An electric work vehicle includes a battery, a motor positioned under the battery and drivable on electric power supplied by the battery, a travel device drivable by the motor, an inverter positioned under the battery and forward of the motor to convert direct-current electric power from the battery into alternating-current electric power and supply the alternating-current electric power to the motor, and a transmission positioned backward of the battery to transmit a driving force of the motor to the travel device, wherein the motor and the inverter are arranged in a front-back direction of a machine body.

An electric work vehicle includes a travel battery, an auxiliary battery, a motor drivable on electric power supplied by the travel battery, a travel device drivable by the motor, a voltage converter positioned forward of the travel battery to step down a voltage of electric power from the travel battery and supply the electric power to the auxiliary battery, and a radiator positioned forward of the travel battery, wherein the voltage converter and the radiator are laterally next to each other in a plan view.

A cooler for a work vehicle includes at least one cooler core, a cooling fan associated with the at least one cooler core to produce a stream of air across the at least one cooler core, and a dust removal assembly including a filter associated with the at least one cooler core such that the stream of air passes through at least one collection surface of the filter. The dust removal assembly includes a suction channel placed such that it does not substantially interfere with the stream of air passing across the at least one cooler core, a blower fluidly coupled to the suction channel and configured to produce a suction region in and adjacent to the suction channel, and a filter carrier configured to carry at least a portion of the filter through the suction region such that particles captured by the filter are pulled into the suction channel.

A drive axle of an electric vehicle has first and a second drive wheels (R1, R2) with wheel axles (a1, a2), a first electric machine (EM1) and a second electric machine (EM2) with a common rotation axis (m), a transmission (G3) with a transmission input shaft (EW) and a transmission output shaft (AW), and an axle differential (DI) with a differential input (DIK) and two differential output shafts (3a, 3b). The first electric machine (EM1) is connected to the transmission input shaft (EW) and the transmission output shaft (AW) is connected to the differential input (DIK). The second electric machine (EM2) can be connected as an additional drive when necessary.

A transmission subassembly for a working vehicle includes an engageable front wheel drive, a transmission housing, a clutch module, and a hydraulic module. The hydraulic module is received between the clutch module and the transmission housing.

The invention relates to a hydraulic device including: a stator and a rotor, in which the rotor can rotate relative to the stator about a first axis of rotation; and a shaft mounted on the rotor such as to rotate therewith. The shaft has a wheel carrier provided at a proximal end thereof and designed to receive a rim and a tire. The shaft includes a through-channel extending from the proximal end to an opposing distal end. The hydraulic device includes an air chamber formed at the distal end of the shaft and connected to the through-channel. The through-channel and air chamber are produced such as to allow a flow of air in order to control the pressure of a tire.

A work vehicle capable of traveling on a public road and in a working field includes: a public road traveling determination unit configured to generate vehicle body position information regarding a position at which the vehicle body is located, determine based on the vehicle body position information whether or not the vehicle body is traveling on the public road, and output a determination result; and a vehicle speed limiter configured to limit a vehicle speed in accordance with the determination result.

A tandem wheel assembly for a work vehicle includes a tandem wheel housing, a center drive member rotatably disposed within the housing, first and second wheel end assemblies, a coupler between each wheel end drive member and the center drive member, and a brake assembly. Each wheel end assembly includes an input shaft, a wheel end drive member mounted thereon, a wheel end gear train coupled to the input shaft, an output shaft coupled to the wheel end gear train, and a wheel end hub coupled to the output shaft for supporting one of the wheels. The brake assembly is coupled to the tandem wheel housing and to the input shaft or the output shaft of at least one of the first wheel end assembly or the second wheel end assembly and reduces the amount of backlash.
