A steering column may include a casing pipe disposed longitudinally movably in a casing unit, a steering spindle rotatably supported about a longitudinal axis in the casing pipe, and a clamping device configurable in a fixing position for securing the casing unit relative to the casing pipe. The clamping device may have an engagement element supported on the casing pipe, having an upper side parallel to the longitudinal axis, and having lateral edge sides. The clamping device may have a locking element supported in the longitudinal direction on the casing unit and that can be moved to adjust the fixing position in a normal direction of the upper side against the engagement element. Positive-locking elements on the locking and engagement elements are engageable to produce a positive-locking connection in the longitudinal direction, at least some of which are disposed on an edge side of the engagement element.

Steering column for a motor vehicle

A plain bearing for a steering spindle of a steering column for a motor vehicle. The bearing includes an inner ring with an axially continuous bearing opening for slidably receiving the steering spindle. A prestressing element is configured to exert a prestressing force on the inner ring to clamp the inner ring on the steering spindle and thereby to assign a defined, uniform braking torque.

Sliding bearing for a steering spindle and steering column for a motor vehicle

A steering column for a motor vehicle, having an inner casing tube which rotatably supports a steering shaft, and an outer casing unit in which the inner casing tube is received movably in the axial direction and is fixable, also having an energy absorption device which is arranged functionally between the casing tube and the casing unit, in which a portion of the energy occurring in the event of a crash can be absorbed when the casing tube is moved telescopically relative to the casing unit, wherein the energy absorption device comprises at least one deformation strip, which is pulled through a brake element and thereby deformed, is improved according to the invention in order to reduce the installation space of the overall steering column in that the deformation strip is fastened on a carrier plate, which in turn is fastened to the casing tube and projects in the axial direction beyond the casing tube.

Steering column having an energy absorption device

A steering column may include an outer casing unit in which an inner casing tube that rotatably mounts a steering shaft is received such that the inner casing tube is displaceable and fixable in an axial direction. An energy absorption device operatively disposed between the casing tube and the casing unit may absorb at least some energy in a crash event where the casing tube is telescopically displaced relative to the casing unit. The energy absorption device may include a deformation strip fastened to but spaced apart from the casing tube, fixed in a radial direction by a spacer on the casing tube, to which deformation strip a deformation slide that is connected to the casing unit is disposed. The deformation slide may encompass and jam outer narrow sides of the deformation strip such that the deformation slide deforms the deformation strip in a crash event.

Steering column comprising an energy absorption device for a motor vehicle

A steering column may include an inner casing tube that rotatably mounts a steering shaft, an outer casing unit in which the inner casing tube is displaceable and fixable in an axial direction, and an energy absorption device operatively disposed between the casing tube and the casing unit. The energy absorption device absorbs at least some energy in a crash event when the casing tube is telescopically displaced relative to the casing unit. The energy absorption device may have at least two deformation strips fastened to the casing tube, and a deformation slide may be disposed on each strip. Each deformation slide may be connected to the casing unit and may encompass and jam external narrow sides of the respective deformation strip so that each deformation slide deforms the respective deformation strip when the deformation slide in a crash event is displaced in the axial direction on the deformation strip.

A steering column with an inner casing tube rotatably mounts a steering shaft. An outer casing unit is connected to a vehicle chassis and the inner casing tube is displaceably received therein and configured to be axially fixable. An energy absorption device is operatively disposed between the casing tube and the casing unit and in which part of the energy arising in the event of a crash is absorbed when the casing tube is telescopically displaced in relation to the casing unit. The energy absorption device is configured to adapt the absorbed energy to the circumstances of the crash event.

Steering column comprising an adaptive energy absorption device for a motor vehicle

A plug-on body for a clamping bolt of an adjustable steering column for a motor vehicle. The plug-on body includes at least one opening for guiding the clamping bolt through the opening of the plug-on body and at least one or two damped elongated hole stops for damping an impact of the clamping bolt on an end of an elongated hole.

Plug-on body for a clamping bolt

A steering column for a motor vehicle, with a bracket unit for fastening the steering column to the motor vehicle bodywork, and with at least one steering spindle bearing unit for the rotatable mounting of a steering spindle of the steering column, and with at least one bending clip for absorbing energy during a movement of the steering spindle bearing unit relative to the bracket unit by means of deformation of the bending tab. At least two bending limbs of the bending tab are connected to one another by at least one bent-over portion of the bending tab. One of the bending limbs is fastened to the steering spindle bearing unit, and the other bending limb is fastened or can be fastened to the bracket unit by at least one connecting device which can be released without being destroyed.

In a plain bearing for a steering spindle of a steering column for a motor vehicle having an inner ring for receiving and slidingly mounting the steering spindle, the inner ring is surrounded by an outer ring, and elastic intermediate pieces are arranged between the inner ring and the outer ring . A respective elastic intermediate piece holds the inner ring at the location of the intermediate piece at a spacing from the outer ring in relation to the radial direction in the unloaded state of the plain bearing and can be compressed in the case of a force which acts on the inner ring and is directed outwards in the radial direction, the inner ring bearing against the outer ring if a limiting value of the radial force is exceeded.
