  • Patent number: 9964169
    Abstract: A damper includes an outer cover having a front cover and a rear cover. The covers are joined to form a lubricant oil accommodation chamber for accommodating liquid. A damper device, a limiter mechanism, a first plate including a first collar portion located toward the front of the limiter mechanism, and a second plate including a second collar portion located toward the rear of the limiter mechanism are arranged in the outer cover. The limiter mechanism includes a first limiter plate, which is an input side on the torque transmission path, a second limiter plate, which is an output side on the torque transmission path, and a limiter disc spring, which presses the limiter plates.
    Type: Grant

  • Patent number: 8439762
    Abstract: A torsional damper includes a torque limiter and a damper. The torque limiter includes at least two friction members, allows transmission of torque, and prohibits transmission of excessive torque. The damper absorbs torsional vibration through resilient deformation of a spring. The torque limiter is a wet torque limiter in which the friction members are arranged in an oil chamber filled with lubricating oil. The damper is a dry damper in which the spring is not immersed in the lubricating oil.
