DUAL SHIFT COUPLING

摘要

The invention relates to a dual shift coupling comprising two operatively connected coupling units, which are mounted on a shared, integrally formed inner body in a rotationally fixed and axially movable manner. The invention further comprises a multi-part pressure disk, which is arranged between the coupling units in an axially fixed manner and is supported by the inner body, and having two axially movable pressure pistons, which can be ventilated by respective pressure spring assemblies arranged in the inner body. According to the invention, a radial notch for accommodating the pressure disk is provided in the inner body, wherein the radial depth of said notch extends at least to radial inner wall segments of recesses for the pressure spring assemblies. Each pressure spring assembly comprises a plurality of pressure springs, which rest on the inner side of the pressure disk relative to the axis. The invention can be used in the manufacture of machine tools.
