The present disclosure provides an electric vehicle comprising a chassis, a front axle and a rear axle spaced apart and coupled to the chassis, and a battery frame assembly coupled to the chassis between the front axle and the rear axle. The battery frame assembly comprises a plurality of transversely extending members and a plurality of longitudinally extending members, wherein the plurality of transversely extending members and the plurality of longitudinally extending members define a matrix of battery pack receptacles configured to receive at least one battery pack. The battery frame assembly is configured to deflect torsionally in response to torsional deflection of the front axle relative to the rear axle.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

The invention relates to a commercial vehicle, in particular a heavy-duty vehicle, comprising a plurality of wheel assemblies mounted on a vehicle frame. At least one of the wheel assemblies comprises an elongate wheel carrier, a wheel at each of the longitudinal ends of the wheel carrier, a drive unit for driving the wheels, and a transmission device. According to the invention, the at least one wheel assembly further comprises a clutch device which selectively interrupts or establishes a power transmission connection between the drive unit and the wheels, and a brake device which is approved for the operation of the commercial vehicle on public roads up to speeds of more than 25 km/h.

The invention relates to a vehicle comprising a chassis having an upper frame plate and a lower frame plate. Between the upper frame plate and the lower frame plate there is provided a traction battery pack arrangement comprising one or more battery modules, and a hydrogen tank structure comprising one or more hydrogen tanks. The hydrogen tank structure is vertically tightened to the traction battery pack arrangement, so that one of the hydrogen tank structure and said traction battery pack arrangement is located on top of the other. At least one of the hydrogen tank structure and the traction battery pack arrangement is tightened to one of the upper and lower frame plates.

The present invention relates to a method for moving a heavy object into a confined space. The method comprises providing the heavy object in an initial position, the heavy object having an underside resting on a ground surface and comprising an inducible gas-cushion arrangement which in its inactive state causes the underside of the heavy object to maintain contact with the ground surface; activating the inducible gas-cushion arrangement by forming a gas cushion between the underside of the heavy object and the ground surface, the gas cushion generating a lifting force causing the underside of the heavy object to lose contact with the ground surface; moving the heavy object relative to the confined space until the underside of the heavy object at least levels with the supporting surface of the confined space; and moving the heavy object into its final position utilizing the lifting force of the gas-cushion.

A dump body includes: a side plate; a flow path which is provided in the side plate and through which an exhaust gas of an engine flows; an exhaust port of the exhaust gas which is provided in an outer surface of the side plate; and a guide surface which has a first inner end portion and a first outer end portion and is inclined downward toward the first outer end portion, the first inner end portion being connected to an outer surface of the side plate below the exhaust port.

A traveling device (11) is provided with an electric motor (16) provided in a vehicle body (2) of a dump truck (1), an output shaft (17) an axial base end of which is connected to the electric motor (16) and which outputs rotation of the electric motor (16), a bottomed hole spline (53) formed in an axial front end of the output shaft (17), and an input shaft (42) which has a shaft spline (54) spline-coupled to the hole spline (53), and inputs the rotation of the output shaft (17) to a reduction gear mechanism (27). The output shaft (17) is provided with an oil reservoir space (55) formed in the innermost part of the hole spline (53), an annular oil groove (56) and an oil path (57) providing communication between the oil reservoir space (55) and the annual oil groove (56). Lubricant oil (100) supplied to the annular oil groove (56) is supplied via the oil path (57) to the oil reservoir space (55), and is supplied to a spline joint between the hole spline (53) and the shaft spline (54) with rotation of the output shaft (17).

The present disclosure relates to a battery assembly for a vehicle comprising a pair of longitudinally extending frame rails, the battery assembly comprising a first and a second vehicle battery module, the first vehicle battery module being stacked vertically on top of the second vehicle battery, wherein the battery assembly is configured to be connected to the vehicle vertically below the frame rails by attaching an upper surface of the first vehicle battery module to a horizontally extending portion of a pair of brackets, the pair of brackets being attachable to a respective one of the longitudinally extending frame rails.

An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section. An antilock braking system sensor bracket engages the antilock braking system sensor bracket locator nub for proper positioning of an antilock braking system sensor.

A work vehicle includes an override operation sensor that senses override operation to carry out switching between an automatic driving mode and a manual driving mode and a selection device for selecting any one of the manual driving mode, a manned automatic driving mode, and an unmanned automatic driving mode, as the driving mode of a dump truck. A controller carries out switching from the manned automatic driving mode to the manual driving mode when override operation is sensed by the override operation sensor in the case in which the manned automatic driving mode is selected by the selection device, and continues the unmanned automatic driving mode when override operation is sensed by the override operation sensor in the case in which the unmanned automatic driving mode is selected by the selection device.
