摘要： Attenuation strips are provided for use in driveshaft dampers, and driveshaft dampers are provided for use in driveshafts to dampen or attenuate aspects of noise, vibration, and harshness (NVH). Systems and methods for making and using driveshaft dampers are further provided. The driveshaft dampers may be made using a helical-winding process and include attenuation strips with elongate protrusions. Various embodiments of helically-wound driveshaft dampers include a core and one or more attenuation strips helically wound around the core.

摘要： A damper device includes an input-side rotor, an output-side rotor, a plurality of elastic members, an intermediate rotor and a hysteresis generating mechanism. The input-side rotor and the output-side rotor are rotatable relative to each other. The plurality of elastic members elastically couple the input-side rotor and the output-side rotor in a circumferential direction. The intermediate rotor is rotatable relative to the input-side rotor and the output-side rotor, and actuates at least two of the plurality of elastic members in series. The hysteresis generating mechanism includes a friction member slidable in contact with the input-side rotor, the output-side rotor and the intermediate rotor, and generates a hysteresis torque in elastic deformation of the plurality of elastic members.

摘要： A power transmission device includes a flywheel and a torque limiter unit fixed to the flywheel. The flywheel includes an annular portion and an accommodation portion provided on an inner peripheral side of the annular portion to accommodate the torque limiter unit. The torque limiter unit includes a first plate, a second plate, a friction disc disposed between the first and second plates, and a pressing member. A torque is inputted to the first plate. The first plate includes first engaging portions. The second plate is axially opposed to and non-rotatable relative to the first plate. The second plate includes second engaging portions engaged with the first engaging portions. The pressing member presses the second plate onto the friction disc. The annular portion of the flywheel is provided with recesses on the inner peripheral surface thereof. The recesses are recessed radially outward in opposed positions to the second engaging portions.

摘要： A torque limiter embedded damper device is provided between a power source-side member and an output-side member. The torque limiter embedded damper device includes a damper unit coupled to the output-side member, and a torque limiter unit that limits torque transmitted between the power source-side member and the damper unit. The damper unit includes first and second plates opposed to each other. The first and second plates have a disc shape. The first plate includes a first coupling portion in an outer peripheral end thereof. The second plate includes a second coupling portion in an outer peripheral end thereof. The first and second coupling portions are coupled to each other. The torque limiter unit includes a friction disc including a third coupling portion in an inner peripheral part thereof. The third coupling portion is coupled to the damper unit and disposed radially inside the first and second coupling portions.

摘要： A torsion shaft assembly includes a torque carrying shaft including a driven end configured for receiving torque input to the torque carrying shaft and a driving end configured for outputting torque output from the toque carrying shaft. The torque carrying shaft includes an axial facing damping interface surface axially between the driven end and the driving end. A friction tube is disposed outboard of the torque carrying shaft. The friction tube is connected at a first axial location to be driven by the torque carrying shaft. The friction tube includes an axial facing damping interface surface that abuts the axial facing damping interface surface of the torque carrying shaft, forming a damping interface to provide frictional dampening against angular vibrations occurring as differential angular displacement between the driven end and the driving end of the torque carrying shaft.

摘要： A torsional vibration damper comprising an input part arranged about an axis of rotation and an output part arranged such that it can rotate relative to same, about the axis of rotation and against the effect of a spring unit is provided. The spring unit is impacted in the peripheral direction respectively on the input side and the output side, and a torque-limiting unit, including a flange part impacting the spring unit on the output side and lateral parts arranged on both sides of the flange part and forming a frictional connection with same by means of an axial clamping, is arranged between the spring unit and a driven part of the output part. The flange part is clamped between a first and a second lateral part by a disc spring axially supported on a counter bearing of the first lateral part and axially pretensioning the second lateral par against the flange part.

摘要： Vehicles that are relatively heavy and/or configured to transport heavy loads may utilize a powertrain comprising an electric machine capable of operating at high speeds and a multispeed transmission to propel the vehicle. An interface module is configured to modulate torque between the electric machine and the multispeed transmission allowing the electric machine to smoothly match speed as the multispeed transmission shifts between gears. The interface module facilitates efficient, predictable, and reliable modulation of torque between an input and an output of the powertrain of the vehicle.
