Torque transmission device for use in drive train of vehicle for transmitting torque of crankshaft of internal combustion engine to gear input shaft, has compression spring pre-stressed between components about radius around rotary axis

摘要

The device (1) has a dual-mass flywheel (4) and a decoupler (5) serially arranged between a crankshaft (2) of an internal combustion engine and a gear input shaft (3) and connected with each other by a releasable connection using a clutch disk (18). The releasable connection is formed by two components of the respective flywheel and decoupler, and a helical compression spring is pre-stressed between the components about a radius around a rotary axis (R), where front sides of the spring are arranged along the radius.
