Abstract:
1. A vibration damping device, comprising: an inertial body, which is configured to dampen torsional vibrations of a rotary shaft transmitting a power of a prime mover to a transmission by an inertia force; an elastic damping mechanism, which is configured to dampen the torsional vibrations by an elastic force of an elastic member thereof; a torque limiter mechanism, which is configured to limit a power transmission in case the power inputted to the rotary shaft exceeds a predetermined value; and a pendulum damping mechanism having a mass adapted to dampen the torsional vibrations by an oscillating motion thereof resulting from the torsional vibrations; wherein the inertial body is arranged in the prime mover side of the rotary shaft, wherein the elastic damping mechanism is connected with a transmission side of the inertial body in a power transmittable manner, wherein the pendulum damping mechanism is connected with the transmission side of the elastic damping mechanism in a power transmittable manner, wherein the torque limiter mechanism is connected with the transmission side of the pendulum damping mechanism in a power transmittable manner, wherein the pendulum damping mechanism is situated outside of the torque limiter mechanism in a radial direction of the rotary shaft, and wherein the pendulum damping mechanism and the torque limiter mechanism are overlapped with each other in the radial direction of the rotary shaft.
