A utility vehicle steering system has a steering gear for transmitting a manual torque that is applied to a steering wheel to a pitman arm. The steering gear has an electric motor for providing an auxiliary torque. The electric motor is arranged around a steering shaft. In addition, the electric motor has a stator with at least two electrically separated winding groups, each of which is controlled by a separate electronic control device. An especially compact utility vehicle steering system results, which enables the provision of large auxiliary torques by way of a single electric-motor drive while a limited installation space is achieved. The drive can be operated from a vehicle electrical system by a supply voltage of 24 V.

A portable storage device to contain fuel. The device is designed to be relatively light-weight to allow for movement around a fueling facility, and to be delivered to the fueling facility through the air. The device includes a number of separate tanks each configured to contain fuel. A suspension protects the tanks by absorbing external forces that could occur in the event the device is dropped during air delivery.

A bearing arrangement for a motor vehicle steering system includes a sleeve arranged between an outer bearing ring and a housing. The sleeve includes an inner contact surface in contact with an outer circumferential surface of the outer bearing ring, and an outer contact surface in contact with a seat surface of the housing, wherein either of the inner contact surface or the outer contact surface of the sleeve are convex shaped.
