Abstract: A powertrain mechanism in a vehicle having an internal combustion engine. The powertrain mechanism is provided for transmitting power from the engine to a gearbox. The mechanism includes at least one drive plate and at least one connection hub. The hub has an assembly section disposed in at least one assembly opening provided in the vicinity of the center of the drive plate. At least one protrusion upper section defines at an uppermost section of at least one protrusion provided mutually on an inner wall of the assembly opening and on an outer wall of the assembly section. At least one recess base defines at a lowermost section of at least one recess wherein the at least one protrusion is at least partially placed. The powertrain mechanism further includes at least one movement gap provided between the protrusion upper section and the recess base.

Abstract: A powertrain mechanism (10) in order to transfer the power, received from the engine, to the gearbox in vehicles having internal combustion engine and comprising at least one drive plate (70) and at least one connection hub (30) having an assembly section (40) placed into at least one assembly opening (71) provided in vicinity of the center of the drive plate (70). As an improvement, the subject matter powertrain mechanism (10) comprises at least one movement gap (90) provided between at least one protrusion upper section (51) defined at the uppermost section of at least one protrusion (50) provided mutually on inner wall (72) of the assembly opening (71) and on outer wall (41) of the assembly section (40), and at least one recess base (61) defined at the lowermost section of at least one recess (60) wherein the protrusion (50) is at least partially placed.
