Abstract: A device for exposing at least one opening in a housing part of a steering gear in a vehicle steering system is provided with a closure element, which closes the opening, and an operating element. At least one of the properties of the operating element changes when coming in contact with a liquid so that the opening can be exposed by the closure element after cooperation of the operating element with the closure element. The closure element is at least partially covered by a cover part and is designed as a buoyant body, or is provided with one or more buoyant bodies, wherein the cover part completely exposes the opening when liquid makes contact with the cover part.

Abstract: In an electric auxiliary power steering system a rotating component driven by a servomotor includes a rolling bearing for axially and radially supporting the component. At least one inner race or one outer race of the rolling bearing is split into two race parts along a parting plane that runs approximately perpendicular to a longitudinal axis of the rotating component. The two parts are axially spring-loaded against one another. The ends of the race parts facing one another are aligned at an angle from the radial outer side thereof to the radial inner side thereof. The element with a conical cross section and having a higher coefficient of thermal expansion than the coefficient of thermal expansion of the outer ring or the inner ring is placed between the ends so that when heat is introduced, the element expands and the race parts are able to move toward one another. When the element cools the race parts can move apart axially.

Abstract: An electric auxiliary power steering system for a vehicle, comprises a rotating component driven by a servomotor and comprises a rolling bearing for axially and radially supporting the component in the frame. At least one inner race or one outer race of the rolling bearing is split into two race parts along a parting plane that runs approximately perpendicular to a longitudinal axis of the rotating component, the two parts being axially spring-loaded against one another, wherein the ends of the race parts facing one another are aligned at an angle from the radial outer side thereof to the radial inner side thereof, and an element with a conical cross section and having a higher coefficient of thermal expansion than the coefficient of thermal expansion of the outer ring or the inner ring is placed between the ends so that when heat is introduced, the element expands and the race parts are able to move toward one another, and when the element cools the race parts can move apart axially.

Abstract: A toothed belt gearing includes a toothed pulley including pulley teeth having a first configuration and a toothed belt including belt teeth having a second configuration. The belt teeth are meshable with the pulley teeth, the first configuration and the second configuration being different from one another and being selected so as to minimize air present in tooth spaces between meshed ones of the belt and pulley teeth as compared to other toothed belt and pulley combinations which share a substantially same tooth configuration, thereby reducing noise radiation resulting from a resonance behavior of the toothed belt normally present in the other toothed belt and pulley combinations.

Abstract: An electromechanical steering system for a vehicle comprises a steering shaft, which is mounted rotatably in an accommodating space of a steering housing, and an electric motor, which, acts upon steering shaft over a transmission. Furthermore, a coil spring housing with a coil spring is provided in the accommodating space. The accommodating space is divided by a partition into a section accommodating the coil spring and a section accommodating the transmission. A damping almond is integrated in the partition. The housing of the coil spring forms part of the partition.

Abstract: In a method for fastening a torque measurement device for detecting a relative torque between an input shaft and an output shaft of a steering system, e.g., of a rack-and-pinion power-assisted steering system, the torque measurement device is integrally formed locally into the input shaft and/or the output shaft by deformation elements.
