Differential side gears (344, 345) geared with a differential pinion gear are disposed inside a differential gear case (347) coupled with a crown wheel (341) of the differential unit, and the brake unit (360) includes a main brake (380) for restricting and stopping the differential gear case (347), and a subsidiary brake (390) for stopping the rotation of the power shaft (349).

A vehicle (10) for a driver (14) of the vehicle (10) and a display device (16) are provided. The display device (16) includes a projection surface (18) extending in the horizontal and vertical direction and a projector (20) that is configured so as to project a projection (24) onto the projection surface (18). The projection surface (18) is curved in the horizontal direction and surrounds the driver (14) in the horizontal direction by at least one hundred degrees. A method for displaying a projection (24) on a projection surface (18) for a driver (14) of a vehicle (10) is also provided. The method includes: d) determining a viewing direction and/or head orientation (26) of the driver (14) towards the projection surface (18); and f) projecting the projection (24) onto the projection surface (18) in the viewing direction and/or head orientation (26) of the driver (14).

The integrated transmission gearbox includes a drive motor transmission mechanism and an oil pump motor transmission mechanism. The integrated motor controller includes a drive motor control unit and an oil pump motor control unit. The integrated transmission gearbox, the integrated motor controller, the drive motor, the oil pump motor, the oil pump and the vehicle controller are completely integrated and mounted to form the liquid-cooled integrative power system for electric forklift.

A steering axle for steering the wheels on the axle of a four-wheel forklift truck by a hydraulic or electric steering device. The steering axle has an axle beam with first and second wheel carriers. The wheel carriers are arranged pivotably on the axle beam. A steering rod is connected, in articulated fashion, to the two wheel carriers in order to transmit steering movements. A steering actuator produces the steering movement and has an actuator housing. The actuator housing has at least one guide section for the passage of the steering rod through the actuator housing. The steering actuator has at least one sliding bearing device for the radial support of the steering rod on the at least one guide section.

A mobile work system and methods for operationally receiving a work performing and/or energy delivering attachment. A work platform is powered by a power output device and includes a source of electricity for powering the attachment. The platform has a first end and a second end generally opposite the first end. A first attachment interface is connected to the first end, and a second attachment interface, substantially operationally equivalent to the first attachment interface, is connected to the second end. The first end of the platform also includes a first steering mechanism, and the second end includes a second steering mechanism substantially operationally equivalent to the first steering mechanism, whereby the platform is configured to be propelled and steered in a first direction and propelled and steered in a second direction generally opposite the first direction by the first and second steering mechanisms, respectively.

An operating method for an industrial truck. The industrial truck includes a hydraulic pump which provides a hydraulic output, an output setpoint value generator which controls the hydraulic output to influence a traveling speed, two drive wheels which respectively comprise a hydraulic drive unit driven via the hydraulic pump, and a hydraulic device. The hydraulic device is switchable between a first switching state, where the hydraulic drive units are supplied with hydraulic outputs which are different, and a second switching state, where the hydraulic drive units are supplied with hydraulic outputs that have a particular ratio with respect to each other. The operating method includes detecting at least one operating parameter of the output setpoint value generator, comparing the at least one operating parameter with a predefined threshold value, and moving the hydraulic device from the first switching state to the second switching state based on the comparison.

The invention relates to a metal hydride hydrogen storage and supply arrangement integrated for use in a fuel cell utility vehicle. The storage arrangement includes a plurality of metal hydride containers suitable to be filled with a metal hydride material, the containers being connectable in parallel to a gas manifold; heat transfer means located between the metal hydride containers; and a filler body located in a space between the metal hydride containers and the heat transfer means.
