Title: DRIVE PLATE FOR TORQUE TRANSMISSION
Abstract:
The invention relates to a drive plate for torque transmission between a driving part, in particular the output shaft of a drive engine, and a driven part, in particular a torsional vibration damper, a clutch and/or a torque converter in motor vehicles. The drive plate is mounted to a drive flange in a radially inner area by means of several fastening bores which are offset from the circumference and to the driven part by means of at least three, radially outer fastening bores. Between the mounting areas, the drive plate is provided with circumferentially distributed recesses in the shape of elongated holes, which are essentially oriented in the circumferential direction. In order to obtain improved strength properties of the drive plate, the recesses (24, 26) are arranged inside and outside of virtual connection lines (28) of the radially outer fastening bores (18).
