摘要： 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.

摘要： 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.

摘要： A steering gear comprises a helical pinion and a helical gear which are mounted in the gear housing and driven by an electric motor, wherein a control unit and a sensor system connected thereto are also disposed in or on the steering gear so as to detect and control the rotor position and/or rotation of the rotor of the electric motor. A section of the shaft of the worm located on the drive side extends in the axial direction and protrudes from the gear housing, wherein the protruding end of the section on the drive side is designed as a rotor shaft of the electric motor, and the control unit and/or the sensor system are disposed on the gear housing. The control unit and the sensor system are preferably disposed on differing sections of the gear housing. This allows a very compact, cost-saving and flexible implementation of the design.

摘要： A vehicle power steering system suppresses chattering, i.e., unpleasant noises in the form of mechanical and generally higher frequency oscillations resulting from backlash in a gear connection transmitting the torque from the motor to the steering wheel mechanics, produced under certain driving conditions. A control system is provided which evaluates the rotor rpm of the electric motor, and increases the dynamic response time of the rotor in the event that the evaluation of the rotor rpm indicates an unstable state of the control system. As a result, chattering is suppressed only when a critical driving situation arises in which the control system becomes unstable, while, in the normal state, the steering system exhibits all properties thereof, and is neither delayed nor limited in a dynamic behavior thereof.
