Expandable stacked thrust bearing assembly

A double row axial roller bearing assembly includes a compressible ring between the two rows. This compressible ring prevents excessive axial forces if the respective shafts impact one another after becoming axially separated. One embodiment is fully unitized such that all parts of the bearing assembly remain with one of the two shafts if the shafts become axially separated. Another embodiment is semi-unitized such that one row of rollers and the compressible ring remain with one of the shafts while the other row of rollers remains with the other shaft. In both cases, all bearing components are prevented from falling out of position such that they return to their proper axial and radial position when the shafts come back together.

Housing element with axially movable bearing unit

A housing element having a casing provided with a cylindrical seat, a bearing unit located inside the cylindrical seat of the casing, a metal ring arranged between the casing and the bearing unit and provided with a spherical seat. The metal ring is assembled inside the cylindrical seat of the casing and is axially movable along the cylindrical seat. The bearing unit is coupled with the metal ring by its spherical seat and is axially movable together with the metal ring. The metal ring is provided with a first groove, which is radially external, and a first radial hole in fluid communication with the first groove so as to allow a supply of grease to the bearing unit.

Axial damper and displacement limit for turbomachine with rolling element bearings

In accordance with one aspect of the present disclosure, a turbocharger having a rolling element bearing (REB) assembly contained within a bearing housing includes an axial damper configured to dampen and limit axial displacement of the REB assembly. The axial damper can include different embodiments, including an elastomeric axial damper, wire mesh, or oil film, for interrupting contact between the bearing assembly and a displacement limit when an axial displacement force exceeds a preload force. Further, the axial damper can include an apparatus having at least two axially compressible rings, where one of the axially compressible rings includes a displacement limit feature.

DRIVE DEVICE FOR A MOTOR VEHICLE HAVING A DRIVE UNIT
20220112945 · 2022-04-14 ·

A drive device for a motor vehicle includes a drive unit with a driveshaft, a housing, and a planetary gear set disposed in the housing with a sun gear. A connection device allows relative movements, running in an axial direction of the driveshaft, between the sun gear and the driveshaft, via which the sun gear is drivable by the driveshaft. An axial bearing has a roller bearing for axially mounting the sun gear where the axial bearing is disposed in the axial direction between the drive unit and the planetary gear set. A bearing casing formed separately from the housing supports the roller bearing in the axial direction via an outer ring of the roller bearing non-rotationally connected to the bearing casing and the bearing casing is connected axially fixedly to the housing.

Suspension thrust bearing device with dust boot retainer

A suspension thrust bearing device provides a lower support cap, an upper bearing cap and at least one bearing arranged between the caps. The lower support cap includes a rigid main body in contact with the bearing, and a flexible vibration damping seat delimiting a bearing surface for the upper end of a suspension ring. The vibration damping seat of the lower support cap is secured to the main body and is provided with at least one retaining hook extending at least in the radial direction and axially offset with respect to the bearing surface on the side opposite to the bearing.

Device for level adjustment for a motor vehicle

A device for level adjustment for a motor vehicle includes a ball screw. The screw nut of the ball screw is driven by an electric motor. The spindle of the ball screw is displaceable with respect to a housing. The ball screw is supported with respect to the housing using two axial self-aligning bearings with a common pivot point such that the housing can pivot with respect to the spindle, thereby avoiding loads on the balls of the ball screw.

HOUSING ELEMENT WITH AXIALLY MOVABLE BEARING UNIT

A housing element having a casing provided with a cylindrical seat, a bearing unit located inside the cylindrical seat of the casing, a metal ring arranged between the casing and the bearing unit and provided with a spherical seat. The metal ring is assembled inside the cylindrical seat of the casing and is axially movable along the cylindrical seat. The bearing unit is coupled with the metal ring by its spherical seat and is axially movable together with the metal ring. The metal ring is provided with a first groove, which is radially external, and a first radial hole in fluid communication with the first groove so as to allow a supply of grease to the bearing unit.

Strut mount bearing unit

A strut mount and bearing assembly includes a strut mount having upper and lower ends, a central bore for receiving a shock absorber end and an annular upper race surface between the upper and lower ends and extending circumferentially about the bore. The upper end is fixedly connectable with a vehicle body and has a flat attachment surface disposeable against a vehicle surface of the vehicle body. A first bearing race is disposed on the mount and a spring seat having a second bearing race is movably coupled with the strut mount.
