摘要： PURPOSE:To provide desirable power transmission structure enabling vibration, generated between transmission members, to be damped over a wide frequency area and also enabling rotatory-driving force to be partially transmitted to the driven side even in the case of an elastic body being ruptured. CONSTITUTION:A rubber body 16 is interposed in the opposed area of a nearly half part between a cylindrical outer cylinder member 11 with a propeller blade 12 erected thereon, and a cylindrical inner cylinder member 13 driven being disposed on the same rotation axis inside the outer cylinder member 11. An operating chamber 31 with silicone oil filled therein is formed at the opposed area of the remaining half part between the outer cylinder member 11 and the inner cylinder member 13. Outer plates 34 and inner plates 35 respectively spline-engaged with the outer cylinder member 11 and the inner cylinder member 13 are alternately disposed in the operating chamber 31.

摘要： PURPOSE: To improve vibrating and damping characteristics by providing flywheel portions and a spring group, consisting of coil springs and setting the spring constants of the springs to be in a range, where vibration generated at the low rotating speed of an engine exceeds a critical point. CONSTITUTION: A torque transmission 1 has a fly wheel 2 divided into two fly wheel portions 3, 4. The fly wheel portion 3 defines a casing for limiting a ring chamber 30, where dampers 13, 14 are stored. Both dampers 13, 14 have a common output in the form of a radial flange 41 arranged between casing portions 31, 32 in the axial direction, and they carry a coil spring 45 of the outside damper 13 at its radially swollen portion 44 extending to the outer periphery of the flange 41 and store a coil spring 48 of the inside damper 14 in a circular window thereof. The spring constants of the springs 35, 48 are set to be in a range where vibration generated at the low rotating speed of the engine exceeds a critical point.

摘要： PURPOSE: To adapt the damping effect of a buffer mechanism to an optimum, in accordance with various operating conditions of an internal combustion engine by forming a spring device supported on a supporting plane which supports the axis of a flywheel at its outside in the radial direction with coil spring groups having long spring strokes. CONSTITUTION: A torque transmission between a motor and a power transmission has a flywheel 2 divided into two flywheel elements 3, 4. The flywheel element 3, on which a friction clutch is mounted forms a casing for limiting an annular chamber 30 accepting dampers 13, 14. Both dampers 13, 14 have a common output portion as a radial flange 41, arranged between both casing halves 31, 32 in the axial direction. A projection on the outer periphery of the flange 41 defines a load accepting range for a coil spring 45 of the outside damper 13. A coil spring 48 of the inside damper 14 is received in a circular window provided on the flange 41.

摘要： PURPOSE: To adapt the damping effect of a buffer mechanism between two mass fly wheels to various operating conditions of an internal combustion engine and to the conditions of different vibrations and noises based on other factors and provide a low manufacturing cost, long service life and less power loss of a drive system with the least wear. CONSTITUTION: Pressure accumulating members of buffer apparatuses 1513, 1513a are accepted and supported in annular chambers 1551, 1551a and flanges 1541, 1541a engaged with a second mass element 1504 in a relatively incapable of turning are moved into the annular chambers, the flange defining the other supporting rage for the pressure accumulating members. The annular chambers are defined by casing portions 1531, 1532 at both sides of the flanges and at least two pressure accumulating member groups for the buffer apparatuses 1513, 1513a which are arranged in parallel in almost substantially the axial direction are provided in the annular chamber.
