Abstract
An electromechanical motor vehicle steering system includes an electric motor and an electronic control unit. The electromechanical motor vehicle steering system is at least partially surrounded by housing parts. At least two of the housing parts are connected to one another by interference fit, wherein the interference fit is at least partly a tapered interference fit.
Claims11
An electromechanical motor vehicle steering system, comprising:
- an electric motor,
- an electronic control unit, and
- housing parts at least partially surrounding the electromechanical motor vehicle steering system,
- wherein at least two of the housing parts are connected to one another by interference fit, wherein the interference fit is at least partly a tapered interference fit, and wherein an internal part of the housing parts connected by means of the interference fit has a peripheral shoulder which delimits the joining distance.
An electromechanical motor vehicle steering system, comprising:
- an electric motor,
- an electronic control unit, and
- housing parts at least partially surrounding the electromechanical motor vehicle steering system,
- wherein at least two of the housing parts are connected to one another by interference fit, wherein the interference fit is at least partly a tapered interference fit, and wherein in a longitudinal direction the interference fit is a combination of a cylindrical interference fit and a tapered interference fit, and wherein an annular groove with an inserted O-ring is provided in the region of the interference fit for sealing between the housing parts.
A method for connecting housing parts of an electromechanical motor vehicle steering system comprising an electric motor and an electronic control unit, comprising:
- providing an internal housing part and an external housing part, wherein the external housing part has an opening with an at least partially tapered internal surface, and wherein the internal housing part has a corresponding taper with a tapered seat surface, wherein the corresponding tapered surfaces form a setting angle;
- and
- positioning the external housing part on the internal housing part and pressing the external housing part onto the internal housing part with a defined axial joining force, and wherein the internal housing part has a peripheral shoulder which delimits a joining distance.
