Torsionally elastic connection between a spoked output wheel and a pump impeller of a hydrodynamic torque converter operating with power division

摘要

In a torsionally elastic connection between the outer ring of a spoked driving wheel, which can be coupled via its hub to an output shaft, and an inner shell of a pump impeller of a hydrodynamic torque converter, spring stop fingers connected in a fixed manner, in terms of motion, to the outer ring are arranged parallel to the axis in the inner torus, and torsion springs inserted between motionally fixed spring stops of the inner shell are arranged tangentially in the inner torus, the terms "parallel to the axis" and "tangentially" each relating to the axis of rotation of the converter. In the event of relative rotations of the outer ring and the inner shell, the torsion springs are each compressed by one of the two spring stop fingers adjacent to one another in the circumferential directions. To achieve low-friction spring guidance, at least one spring cage taking the form of a ring sector with a hollow profile and having the spring stop faces for the insertion of at least one torsion spring is connected to the inner shell and provided with an opening on each of its ends.
