Abstract
A decoupling device for separating a motor from a powertrain, having a piston which is movably mounted in a housing parallel to a longitudinal axis L of the housing and which has an arm for directly or indirectly actuating a coupling element. A first region of the piston is operatively connected to a first pressure chamber such that when pressure is applied to the first pressure chamber, the piston is moved in a first direction parallel to the longitudinal axis L. A second pressure chamber is provided which is operatively connected to a second region of the piston such that when pressure is applied to the second pressure chamber, the piston is moved in a second direction parallel to the longitudinal axis L, the second direction being opposite the first direction.
Claims14
A decoupling device for separating a motor from a drive train, the decoupling device comprising:
- a housing;
- a springless piston movably mounted in the housing parallel to a longitudinal axis of the housing, the piston having an arm for actuating a coupling element;
- a first region of the piston is operatively connected to a first pressure chamber such that when pressure is applied to the first pressure chamber, the piston is moved in a first direction parallel to the longitudinal axis, the first region including a first seal coupled to a first axial end face of the springless piston;
- and
- a second pressure chamber which is operatively connected to a second region of the piston such that when pressure is applied to the second pressure chamber, the piston is moved in a second direction parallel to the longitudinal axis, said second direction being opposite the first direction, the second region including a second seal coupled to a second axial end face of the springless piston.
A decoupling device for separating a motor from a drive train, the decoupling device comprising:
- a housing;
- an annular piston movably mounted in the housing parallel to a longitudinal axis of the housing, the annular piston having a radially extending arm for actuating a coupling element;
- a first region of the piston is operatively connected to a first pressure chamber such that when pressure is applied to the first pressure chamber, the piston is moved in a first direction parallel to the longitudinal axis;
- and
- a second pressure chamber which is operatively connected to a second region of the piston such that when pressure is applied to the second pressure chamber, the piston is moved in a second direction parallel to the longitudinal axis, said second direction being opposite the first direction;
- wherein the first region is located at a first longitudinal end of the piston, and the second region is formed by an indentation in a lateral surface of the piston at the first longitudinal end of the piston;
- and
- wherein each of the first and second pressure chambers is equipped with one respective pressure connection, and the first pressure connection of the first pressure chamber is oriented non-parallel with the second pressure connection of the second pressure chamber.
