US 2010/0140037 A1 · COUPLING ARRANGEMENT

Abstract

The invention relates to a coupling arrangement comprising a component (6) fixed to a housing, a piston (2) that is located rotatably about an axis of rotation (ω) relative to the component (6) fixed to a housing, a rotatable component (1) designed as a component mounted rotatably about the axis of rotation (ω) relative to the component fixed to a housing and having a chamber (8) in the front region of the piston (2), a line arrangement (4) forming a communication line through the component (6) fixed to a housing and the rotatable component (1) to the chamber (8) for a pressure medium, and a rotary feedthrough seal (3) sealing the line arrangement (4) between the component (6) fixed to a housing and the rotatable component (1), wherein a radial inner distance (ri) and/or a radial outer distance (ra) of the piston (2) from the axis of rotation (ω) is less than a radial seal distance (r0) of the rotary feedthrough seal (3).

Dependent claims

A clutch arrangement comprising:

a housing-fixed component (6);
a piston (2) that is arranged so as to be rotatable about a rotational axis (ω) relative to said housing-fixed component (6);
a rotatable component (1) that is, relative to said housing-fixed component (6), arranged around said rotational axis (ω) and has a chamber (8) in an end-side region of said piston (2);
and
a line arrangement (4) that, for a pressure medium, forms a communication line through said housing-fixed component (6) and rotatable component (1) to said chamber (8), wherein, proceeding from said rotational axis (ω), at least one of a radial inside distance (ri) and a radial outside distance (ra, ra*) of said piston (2) is smaller than a radial seal distance (r0) of a rotary leadthrough seal (3).
