Problems solved by technology

This construction has the disadvantage that during operation of the torque coupling not only the spacer pins or the riveted connection are subjected to shear stresses, but also bending forces also act additionally which can reduce the service life of the connection

Abstract

A torque coupler comprises an input side and an output side, which are rotatably disposed about a rotational axis, further an intermediate disk for coupling to the input side, an output flange for coupling to the output side, a spring damper for coupling the intermediate disk to the output flange and a centrifugal-force pendulum having a pendulum flange and a pendulum mass. The pendulum flange extends between a first region, in which the pendulum flange is fastened to the intermediate disk, and a second region, in which the pendulum mass is mounted on the pendulum flange. The output flange has a cutout section through which a portion of the pendulum flange connecting the two regions runs.

Description

Technical field [0001] The invention relates to a torque coupler, especially used in the drive train of a motor vehicle. Background technique [0002] Torque couplers are used for torque transmission in the drive train of motor vehicles. The torque coupling provides, on the one hand, a torque-locked connection between the driven shaft of the drive motor and the drive shaft of the transmission, and on the other hand is provided for damping or eliminating torsional vibrations that are superimposed on the transmitted torque. To this end, the torque coupler includes a spring damper and a centrifugal force pendulum. The spring damper includes an elastic element whose end is connected to the input side or the output side of the torque coupler so as to compress or decompress the spring damper under the influence of the torque change. The centrifugal force pendulum includes a pendulum flange, and the pendulum mass is arranged on the pendulum flange in a manner that can move in the plan...
