A transport vehicle includes a vehicle body, a drive unit, and a coupling device coupling the vehicle body with the drive unit. The drive unit includes a wheel, a travel drive source configured to drive the wheel in such a manner as to rotate the wheel, and a steering device configured to turn the wheel around a steering axis along an up-down direction. The coupling device includes an attachment section attached to the vehicle body, and an adjustment mechanism allowing a reference direction to be changed around the steering axis relative to a front-rear direction of the vehicle body by changing an attachment orientation of the attachment section relative to the vehicle body.

A floor structure (1) of a motor vehicle has a vehicle floor (2). A central tunnel (3) extends in a longitudinal direction of the motor vehicle and is connected to the vehicle floor (2). Two seat crossmembers (4a, 4b) are spaced apart from one another in a transverse direction of the motor vehicle and the central tunnel (3) extends between the seat crossmembers (4a, 4b) in sections. The floor structure (1) has regions of attachment to the central tunnel (3) on both sides of the central tunnel (3) and cast bridges (5a, 5b) are inserted into the floor structure (1) in the regions of attachment to the central tunnel (3).

An axle assembly includes an axle, an axle mount configured to be attached to the axle, a positional locater that projects from an outer surface of the axle and is configured to locate an initial position of the axle relative to the axle mount, and an axle adjustment device comprising an inclined surface that contacts the positional locater. A compressive force is exerted between the axle mount and the axle adjustment device when the axle adjustment device is placed in contact with the positional locater to maintain the initial position of the axle.

A drill rig with a steering system may include a substructure having a wheelhouse, a drill floor arranged atop the substructure, a mast extending upwardly and above the drill floor, and a steering system arranged within the wheelhouse. The steering system may include a wheel assembly comprising an electric motor configured for driving rotational motion of a wheel, a deployment device configuring for deploying the wheel assembly to carry the drill rig, and a steering mechanism configured for selective engagement with the wheel assembly and rotating the wheel assembly.
