Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a rotational force and/or a thrust force is applied between the assemblies.

A rolling bearing includes an outer ring, an inner ring, a plurality of rolling bodies, and a seal member. An outer peripheral portion of the seal member is fixed by a retaining ring to a groove portion formed on an inner peripheral surface of the outer ring and an inner peripheral portion of the seal member is elastically deformable. The seal member includes an inclined portion. The seal member satisfies 0.25≤Skn/Skt≤2.5 when Skn is a radial length from an inclination start part of the inclined portion on an inside in an axial direction to an outermost diameter position of a part of contact of the seal member with an outer peripheral surface of the inner ring and Skt is a thickness of the inclined portion in a direction perpendicular to an inclination direction.

A flexible cartridge assembly can include a flexible shell that includes a flexible portion disposed between a compressor-side portion and a turbine-side portion, where the flexible portion includes a series of arc-shaped cutouts disposed axially along at least a portion of the flexible portion; a compressor-side bearing assembly; and a turbine-side bearing assembly.

A bush pin is provided for a V-stay presenting two arms adapted to structurally connect an axle casing for a vehicle wheel axle to a respective of a left and right vehicle frame member, including a central bush portion and a fastening portion on each side of the central bush portion, wherein each of the fastening portions is adapted to be connected to a bracket by a fastening arrangement, wherein the bush pin includes a first contact surface on each side of the central bush portion, and displaced from the fastening portions, for contacting a corresponding contact surface of the bracket in order to transfer loads.

A rolling bearing includes a cage constructed by coupling a pair of split members that are split into halves in an axial direction of the rolling bearing. At least one of the split members has an engagement portion that protrudes in the axial direction toward the other one of the split members. The other one of the split members has an engagement groove that extends along the axial direction and houses the engagement portion. The engagement groove has an insertion port through which the engagement portion is inserted in the axial direction. The insertion port is formed at an end of the engagement groove that is closer to the one of the split members. At least one circumferential face of the engagement groove includes a first inclined surface that increases a circumferential width of the insertion port toward the one of the split members.

A bearing unit having a radially outer ring, a radially inner ring, a row of rolling elements interposed between the outer ring and the inner ring, a shaped sealing screen interposed between the inner ring and the outer ring and stably inserted inside a first seat of the outer ring, and a snap ring stably inserted inside a second seat of the radially outer ring and interacting with the shaped screen so as to lock it in the first seat.

Systems, apparatuses, and methods of a variable position ball joint with dynamic length are disclosed and include a ball, and a seat with a guide surface; an arc of the ball defines endpoints of an arc path for revolving the ball in the guide surface; a center point of the ball is concentric with a center of rotation of the seat so that the center point of the ball and the seat move in a single axis of movement; and an interface that guides the ball along the guide surface, wherein the guide surface is parallel to the single axis of movement to cause the ball to traverse the seat travel arc while maintaining a center of rotation concentric with the seat resulting in a change in length of an attached component with respect to a concentric center point of rotation during an articulation action of the ball joint.

A crankshaft assembly for a motor vehicle drive train, including a crankshaft segment and a centrifugal pendulum secured thereon, which has a carrier secured to the crankshaft segment and at least one pendulum mass that moves relative to the carrier along a predetermined track. The crankshaft assembly has a friction unit connected to the carrier, which rests on the at least one pendulum mass such that, with a relative movement of the pendulum mass in relation to the carrier, the friction unit applies a frictional torque on the pendulum mass counteracting the relative movement, wherein the friction unit extends over a peripheral section of less than 360°.

A torque transmitting ball joint can include a spherical ball, a stem extending from the spherical ball, one or more pins coupled to the spherical ball, and a socket. The socket can define an opening sized to contain the spherical ball within the socket and one or more slots sized to accommodate a pin of the one or more pins. The one or more pins can be contained by the one or more slots and can translate within the slot as the spherical ball rotates relative to the socket about a pivot center. At least one of the one or more pins can abut a sidewall of its slot and transmit torque from the stem to the socket via the spherical ball when the stem and spherical ball rotates relative to the socket.

A sliding member includes a resin overlay layer on a sliding-surface side of a bearing alloy layer. The resin layer includes a resin binder and 20% by volume or more of solid lubricant particles with an anisotropic shape dispersed in the resin binder. The sliding surface is located at 0° and has a virtual axis perpendicular to the sliding surface at 90°. An angle θ is formed by a straight line and a major axis of the particles. The total number of the particles in a observation region is N. A rate R1=N1/N of the number N1 of first particles at the angle θ of 70°≤θ≤90° from among the particles is 3%≤R1≤20%, and a rate R2=N2/N of the number N2 of second particles with the angle θ being θ≤20° is 35%≤R2≤65%.
