| 摘要 |
The invention relates to a heavy goods vehicle in which the steering system (12) comprises, in addition to a normal steering mode steering device (26) that transfers steering power purely mechanically by means of connecting rods (34) from axle to axle, a crab steering mode steering device (28) that also transfers steering power purely mechanically by means of connecting rods (46) from axle to axle. The individual wheel assemblies (14, 16, 18, 20, 22, 24) can be connected by means of coupling devices (56) either to the normal steering mode steering device (26) or to the crab steering mode steering device (28). |

1. Heavy goods vehicle (10) comprising
a plurality of axles, each of which comprises at least one left wheel assembly (16, 20, 24) and at least one right wheel assembly (14, 18, 22), a steering system (12), which is configured so that it enables both a normal steering mode in which the left wheel assemblies (16, 20, 24) and the right wheel assemblies (14, 18, 22) each have a steering angle which is dependent on the position of the respective axle in the longitudinal direction (L) of the vehicle (10), the wheel assemblies of adjacent axles having a different steering angle from one another, and a crab steering mode in which the wheel assemblies (14, 16, 18, 20, 22, 24) assigned to the plurality of axles all have the same steering angle, characterised in that the steering system (12) comprises for each axle:
at least one steering rotary element (52) which is rotatable about an axis of rotation (D) and is in steering connection with the at least one left wheel assembly (16, 20, 24) and/or the at least one right wheel assembly (14, 18, 22) of the axle,for each steering rotary element (52) a normal steering mode steering power introduction unit (38) assigned thereto,for each steering rotary element (52) a crab steering mode steering power introduction unit (42) assigned thereto,for each steering rotary element (52) a coupling device (56), which connects the steering rotary element (52) either to the normal steering mode steering power introduction unit (38) or to the crab steering mode steering power introduction unit (42) in a rotationally engaged manner, the steering system (12) also comprising:
at least one normal steering mode connecting element (34), which connects the normal steering mode steering power introduction units (38) of axles that are adjacent to one another in the longitudinal direction (L) of the vehicle (10),at least one crab steering mode connecting element (46), which connects the crab steering mode steering power introduction units (42) of axles that are adjacent to one another in the longitudinal direction (L) of the vehicle (10), andat least one power device (32, 84) which is arranged on the vehicle and is connected to at least one of the steering power introduction units (38, 42) and provides the steering power. |
