The invention relates to an axle assembly and a heavy-duty vehicle having such an axle assembly, which comprises a pivot bearing having a substantially vertically extending steering axis of rotation, a bogie rotatably arranged about the steering axis of rotation, a rocker mounted on the bogie so as to be pivotable about a substantially horizontal pivot axis, a wheel carrier operatively connected to the rocker having at least one wheel rotatably mounted thereon about a wheel axis of rotation, the wheel axis of rotation extending substantially horizontally and, when driving straight ahead, substantially transversely to the direction of travel, and a pneumatically actuatable power device, which is arranged between the rocker and the bogie.

Axle assembly for a heavy-duty vehicle and heavy duty-vehicle having at least one such axle 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.

Commercial vehicle, in particular heavy-duty vehicle, and wheel assembly for such a commercial vehicle

A heavy goods vehicle () having a vehicle frame () and at least one driving axis (A), which has on either longitudinal side () of the vehicle () a bogie () comprising a wheel assembly (), each wheel assembly () comprising at least two wheels arranged symmetrically in relation to a central axis (S), and a wheel suspension () by means of which said wheel assembly is fastened to a rotary plate () of the bogie (), this rotary plate () being mounted on a rotary bearing () of the bogie () which is engaged with the vehicle frame () so as to be rotatable about a steering swivel axis (X). According to the invention, the rotary bearing () of the bogie () can be adjusted in the width direction (B) of the vehicle relative to the vehicle frame () and can be detachably connected to the vehicle frame () in an operationally stable manner.

Width-adjustable heavy-goods vehicle

The invention relates to a heavy goods vehicle in which the steering system () comprises, in addition to a normal steering mode steering device () that transfers steering power purely mechanically by means of connecting rods () from axle to axle, a crab steering mode steering device () that also transfers steering power purely mechanically by means of connecting rods () from axle to axle. The individual wheel assemblies () can be connected by means of coupling devices () either to the normal steering mode steering device () or to the crab steering mode steering device ().
