摘要： A sealing device of a bearing. The sealing device includes a framework, a sealing component and a plurality of elastic members, wherein the framework and the sealing component are both annular and connected to each other, and the framework is configured to be fixed to a first ring of a bearing. The sealing component is configured to abut against a second ring of the bearing the plurality of elastic members are distributed at intervals in the circumferential direction of the sealing component, and the elastic members are used for applying an elastic force to the sealing component such that the sealing component is pressed against the second ring. A bearing is also provided.

摘要： An electric drive unit includes an electric motor and a housing that houses the electric motor. The housing includes a heat exchanging wall portion that includes an inner surface that defines a fluid jacket cavity for conveying a first fluid and an outer surface that is opposite the inner surface and that defines a fluid chamber for conveying a second fluid. The heat is transferred between the first and second fluids through the heat exchanging wall portion.

摘要： In one aspect, an improved electric transmission assembly is provided that includes a hydrodynamic bearing. The electric transmission assembly includes a stator arranged inside of an outer housing. A rotor is configured to be rotatably driven by the stator. The rotor can include a rotor shaft having a first gear configured to driveably engage with a differential. A hydrodynamic bearing is arranged between the rotor shaft and the outer housing. The hydrodynamic bearing is formed from a non-conductive material. Specifically, the hydrodynamic bearing can be formed from a polymeric or plastic material. In one aspect, the hydrodynamic bearing is formed from a non-metallic material.

摘要： A stator for an electric machine having a winding and a connection ring which can be placed axially on the winding and is intended for connecting the winding of the stator. The connection ring has a ring-shaped or ring-segment-shaped plastics body with at least three conductors which are each associated with a phase and are interconnected, and the ends of at least some of the conductors protrude axially beyond the winding. The connection ring has a connector terminal which can be interlockingly connected to the ring and which has at least three electrical connector portions. When the connection ring and the connector terminal are joined together, each contact a conductor of the connection ring that is associated with a phase and each electrically conductively connect to a connector of the connector terminal by the connection ring and the connector terminal having interlocking structure which define a defined position of the connection ring and the connector terminal relative to one another.

摘要： A drive assembly including a primary inertia plate and clutch. The primary inertia plate is configured to be rotationally driven via a crankshaft. The clutch plate includes a body with a rotational axis (X). The clutch plate is configured to be rotationally driven by the primary inertia plate. The clutch plate includes at least one imbalance feature such that a center of gravity of the clutch plate is positioned away from the rotational axis (X). The imbalance feature generates a centrifugal force that counteracts or prevents rattling from being imparted to the clutch plate via engine vibrations through the primary inertia plate.

摘要： A centrifugal pendulum for a motor vehicle drivetrain includes a carrier, a pendulum mass, mounting for pivoting relative to the carrier, and a roller body. The carrier has a carrier roller track and the pendulum mass has a pendulum mass roller track. The roller body has a first rolling region arranged in the carrier roller track and a second rolling region arranged in the pendulum mass roller track. The carrier roller track is formed at least partially by an axially formed sheet-metal portion having a free edge, and the free edge faces away from the pendulum mass.

摘要： A valve includes a valve axis extending in an axial direction, a valve housing, a ring that surrounds the valve axis, a seal, a spring for exerting a spring force, and a piston arranged in the valve housing. The valve housing includes a first valve housing opening through which a flow medium can pass. The ring is secured to the first valve housing opening. The seal is held on the valve housing by the ring. The piston is coaxial to the valve housing on the valve axis and axially faces the first valve housing opening. The piston is axially movable in the valve housing against the spring force, and the first valve housing opening can be closed by the piston.
