    摘要: A damper device is disposed between an engine and a transmission and has a torque distribution mechanism that is provided with a first input element connected to the engine, a second input element connected to the engine via an elastic member, a first output element connected to the transmission, and a second output element connected to the transmission. The damper device further has a first clutch that is disposed between the first output element and the transmission, and is switched between an engaged state of connecting the first output element to the transmission and a released state of disconnecting the first output element from the transmission, and a second clutch that is disposed between the second output element and the transmission, and is switched between an engaged state of connecting the second output element to the transmission and a released state of disconnecting the second output element from the transmission.

    摘要: A technique facilitates protection of a sensitive component, e.g. a well tool component, against shock and vibration. The sensitive component may be positioned in a mechanical chassis which is mounted in a housing. The mechanical chassis is mounted in the housing via a damper system which may comprise various vibration and shock absorbing components, such as a vibration damper, a transverse shock damper, and/or an axial damper. In drilling applications, the housing may be coupled into a drill string although the damper system may be used in other types of applications.

    摘要: A damper assembly for a motor vehicle drive train is provided. The damper assembly includes a spring retainer retaining arc springs; an engine-side cover for connecting to an engine crankshaft, the spring retainer being fixed to the engine-side cover; and a seal configuration between the engine-side cover and the spring retainer. The seal configuration, the engine-side cover and the spring retainer define an arc spring cavity for lubricating fluid to lubricate the arc springs. The seal configuration is configured to prevent lubricating fluid from radially exiting the arc spring cavity during rotation of the damper assembly about a center axis thereof. A method of forming a damper assembly is also provided.
