A front axle of a vehicle, configured for reducing vibration, which is connected to a knuckle having a front wheel disposed thereon through a king pin, in which a gap may be formed between the knuckle and the king pin passing through the front axle and the knuckle, and filled with lubricant oil, and at least one of the king pin and the knuckle may include a plurality of rollers disposed therein, the rollers having an axis parallel to an axial direction of the king pin while circumferences of the rollers are partially buried in at least one of the king pin and the knuckle.

A bearing holder includes an inner portion and an outer portion, wherein the inner portion includes a receiving contour for receiving the bearing and the outer portion is configured to be mounted on a housing. A transition area between the inner portion and the outer portion includes a spring. The transition area is at least partly in a plane perpendicular to an axial axis of the receiving contour and is at least partly in a plane with at least one part of the inner and the outer portion. The transition area includes an attenuator and the attenuator is configured to attenuate a vibration of the inner portion to reduce a transfer of the vibration from the inner portion to the outer portion. Further, an electric motor, a method for producing a bearing holder and a method for operating a bearing holder are described.

This aerodynamic foil bearing has a sleeve (4) inside which are arranged: a foil referred to as the top foil (16), and a bump foil (14) arranged between the top foil (16) and the sleeve (4), a foil (12) of viscoelastic material arranged between an inner face of the sleeve (4) and the bump foil (14).

A bearing system and method may include a bearing element that may have a first surface. A mating element may have a second surface that may face the first surface. A fluid film interface may be defined between the first and the second surfaces. The mating element may rotate about an axis and relative to the bearing element. An axial direction may be defined parallel to the axis. A radial direction may be defined perpendicular to the axis. The first surface may have a profile that may vary in the axial direction and that may varies in the radial direction. The profile may direct a fluid present in the fluid film interface in a direction or directions having circumferential and/or axial components.

A tolerance ring for a torque transmission device is arranged in an annular space between an inner shaft member and an outer shaft member. The tolerance ring has a ring-shaped portion and a plurality of protrusions. The ring-shaped portion has a cylindrical shape and is brought into contact with one of the shaft members. The plurality of protrusions undergo elastic deformation and are arranged in a peripheral direction. The ring-shaped portion has seat portions formed between the protrusions that are adjacent to each other in the peripheral direction. The plurality of protrusions include selected protrusions that have the same shape and that are situated at the same axial position and unselected protrusions other than the selected protrusions. The selected protrusions and the unselected protrusions differ from each other in axial position of center point in a length direction.
