A steering assembly for a vehicle comprising a first, a second, a third, and a fourth wheel, a first steering actuator comprising a first actuating member, and a second steering actuator comprising a second actuating member. The first actuating member is connected to each of the first wheel and the second wheel. The second actuating member is connected to each of the third wheel and the fourth wheel. The steering assembly comprises a connection arrangement. The first and second steering actuators are connected to each other via the connection arrangement such that the first actuating member and the second actuating member move independently of each other when a relative movement parameter is within a predetermined relative movement range and the connection arrangement transfers movement between the first actuating member and the second actuating member when the relative movement parameter is outside the predetermined relative movement range.

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).

A motor vehicle for piloted driving including a front axle steering system and a rear axle steering system. In the active, trouble-free driving state with a piloted driving, the driving task for steering the front axle is performed by a front axle steering control which automatically controls the front axle steering system. A failure of the automatic front axle steering control is automatically recognized with a failure recognition device and the vehicle steering is taken over by the rear axle steering system. The motor vehicle is equipped with a device for controlled wheel-selective brake intervention. In case of a failure of the automatic front axle steering control, this device is controlled in such a way that an automatic centering of the front axle steering system is performed by wheel-selective braking interventions.

A mobility vehicle includes a body part, a movement part, and at least one variable frame. The movement part includes a wheel configured to move the body part, and a steering region configured to rotate the wheel about a steering rotation axis relative to the body part and steer the wheel. The at least one variable frame is configured to connect the body part and the movement part, move relative to the body part in a guide direction intersecting the steering rotation axis, and change a spacing distance between one region of the body part and the movement part.
