Abstract
The present disclosure relates to an adjusting device for adjusting the swash plate of an axial piston machine comprising an adjusting piston, which is connected to the swash plate of the axial piston machine via an adjusting lever, and a regulator for adjusting the adjusting pressure acting on the adjusting piston in dependence on a control force acting on a control piston of the regulator, wherein the adjusting piston is connected to the control piston via a feedback spring.
Claims21
An adjusting device for adjusting a swash plate of an axial piston machine comprising:
- an adjusting piston, which is connected to the swash plate of the axial piston machine via an adjusting lever, and
- a regulator which adjusts adjusting pressure acting on the adjusting piston in dependence on a control force acting on a pot-shaped control piston of the regulator, wherein the adjusting piston is connected to the pot-shaped control piston via a feedback spring, wherein the feedback spring is at least partly received in a cylindrical recess of the pot-shaped control piston.
A method of assembling an adjusting device for adjusting a swash plate of an axial piston machine comprising:
- an adjusting piston, which is connected to the swash plate of the axial piston machine via an adjusting lever, and
- a regulator which adjusts adjusting pressure acting on the adjusting piston in dependence on a control force acting on a control piston of the regulator,
- inserting the adjusting piston into an adjusting piston receiving bore from one side and inserting the control piston into a control piston receiving bore from another side;
- connecting the adjusting piston receiving bore to the control piston via a feedback spring, which is at least partly received in a pot-shaped recess of the control piston;
- and
- wherein the control piston receiving bore and the adjusting piston receiving bore merge into each other, and the adjusting piston receiving bore has a larger diameter than the control piston receiving so that a shoulder is formed.
