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

A heavy-duty vehicle having at least one axle assembly, wherein the at least one axle assembly 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 horizontally extending 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 the heavy-duty vehicle straight ahead, substantially transversely to a direction of travel of the heavy-duty vehicle, the wheel carrier being arranged on a portion of the rocker which is located between a free end of the rocker and an additional end of the rocker that is pivotably connected to the bogie;
• and
• a pneumatically actuatable power device, which is supported, at a first end of the pneumatically actuatable power device, on the bogie or on a part connected thereto and, at a second end of the pneumatically actuatable power device, on or adjacent to the free end of the rocker, wherein the pneumatically actuatable power device is arranged behind the steering axis of rotation of the pivot bearing relative to a forward direction of travel.

An axle assembly which is designed and intended to be used in a heavy-duty vehicle, the axle assembly comprising:

• 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 horizontally extending 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 a direction of travel;
• and
• a pneumatically actuatable power device, which is supported, at a first end of the pneumatically actuatable power device, on the bogie or on a part connected thereto and, at a second end of the pneumatically actuatable power device, on the rocker or on a part connected thereto, wherein the second end of the pneumatically actuatable power device is supported on a reversing lever, which is connected to the rocker in an operatively fixed manner and protrudes substantially orthogonally therefrom.

• 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 horizontally extending 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 a direction of travel, wherein the wheel carrier comprises a bearing unit having bearing rings which are separable in a circumferential direction of the bearing unit and which are adapted for a radial bearing assembly on the rocker;
• and
• a pneumatically actuatable power device, which is supported, at a first end of the pneumatically actuatable power device, on the bogie or on a part connected thereto and, at a second end of the pneumatically actuatable power device, on the rocker or on a part connected thereto.
