【発明の名称】ねじり振動を減衰するための装置
Document Type and Number:
Japanese Patent JP3159994
Kind Code:
B2
Abstract:
That flywheel of a torsional vibration damping apparatus which is connected to the crankshaft of an internal combustion engine in a motor vehicle has a concentric annular lubricant-containing compartment for a relatively small number of elongated arcuate coil springs which bear against the teeth of a flange secured to a second flywheel which is coaxial with the first wheel and carries a friction clutch. The latter can be engaged to transmit torque from the second flywheel to the input element of a variable-speed transmission in the power train of the motor vehicle. The compartment of the first flywheel is lined by resilient shells which are installed in stressed condition and at least substantially surround the coil springs. The shells have integral abutments for the end portions of the springs, or the abutments are fixed to or alternate with arcuate portions of the shells. When the magnitude of torque which is transmitted by the first flywheel exceeds a preselected value, the first flywheel slips relative to the shells to thus prevent the transmission of torque peaks or surges to the second flywheel.
