  • Patent number: 12545318
    Abstract: 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.

  • Patent number: 12179858
    Abstract: A shaft arrangement for a steering gear has an input shaft, an output shaft and a torsion rod. The torsion rod is connected in a rotationally secure manner to the input shaft in an input-side connection region of the shaft arrangement. The torsion rod is connected in a rotationally secure manner to the output shaft in an output-side connection region of the shaft arrangement. The input-side connection region is spaced apart from the output-side connection region. The shaft arrangement has a rotation prevention member, wherein the rotation prevention member limits a rotation of the input shaft relative to the output shaft to a maximum rotation angle and, when the maximum rotation angle is reached, can transmit a torque from the input shaft to the output shaft.

  • Publication number: 20240199119
    Abstract: A power steering assembly for an electromechanical power steering system of motor vehicles, in particular utility vehicles, includes a steering gear, the steering gear being designed to transmit a rotational movement introduced by a steering element such as a steering wheel, via an input side of the steering gear, to an output side of the steering gear. The power steering assembly converts 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. An adjustable absorption unit is provided for at least partially absorbing roadside shocks which have been absorbed via the wheel of the motor vehicle. A separate preloading unit is designed to interact with the adjustable absorption unit such that a predetermined preloading force is exerted onto the adjustable absorption unit.
