ABSTRACT:
A dual clutch engine coupling damper includes a slipping ECCC clutch in series with a plurality of damper springs, and a bypass clutch in parallel with the damper springs. The ECCC is adapted for use when the vehicle engine is running and the bypass clutch is adapted for use when the vehicle engine is being started. The dual clutch engine coupling damper incorporates a single pressure plate design adapted to actuate both the ECCC clutch and the bypass clutch. The single pressure plate design is compact and minimizes axial space requirements for the apparatus. Additionally, the components of the present invention are primarily stamped parts which may be produced in an inexpensive and efficient manner.
