An I-shaft assembly includes an upper shaft extending along an axis between a first upper end and a first lower end bounding a first hollow bore. An intermediate shaft extends along the axis between a second upper end and a second lower end bounding a second hollow bore. The second upper end is disposed in the first hollow bore. A lower shaft extends along the axis between a third upper end and a third lower end disposed in the second hollow bore. The upper shaft is releasably fixed for controlled movement along the axis relative to the intermediate shaft, and the lower shaft is releasably fixed against movement along the axis relative to the intermediate shaft during a normal operating condition. The upper shaft moves along the axis relative to the intermediate shaft and the lower shaft moves along the axis relative to the intermediate shaft during an abnormal operating condition.

A power steering assembly for an electro-mechanical power steering system of motor vehicles, in particular utility vehicles, includes a steering gear. The steering gear is designed to transmit a rotational movement introduced by a steering element, in particular by a steering wheel, via an input side of the steering gear, in particular via an input shaft of the steering gear, to an output side of the steering gear. The power steering assembly is designed to convert a movement derived from the output side of the steering gear into a rotational movement of at least one wheel of the motor vehicle about a steering axis. The power steering assembly is characterized in that the power steering assembly has an absorption unit for at least partial absorption of roadside shocks from the wheel of the motor vehicle.

The present disclosure relates to an assembly for a steering system of a vehicle, the assembly comprising an axle part having a coupling recess, and a steering cylinder having a coupling projection. The coupling projection is received in the coupling recess and an interference fit is formed between the coupling projection and the coupling recess.
