Steering device and method for producing a steering device
A steering device includes a steering housing configured to receive and/or to hold at least one steering component, the steering housing including at least one housing section that is made from synthetic material, and a sensor unit which is configured to detect at least one detection variable. The sensor unit is configured to detect a surface characteristic of the at least one steering component and/or to detect a foreign substance penetrating the steering housing. The sensor unit is connected in a bonded manner to the at least one housing section and is integrated and/or embedded at least to a large extent in the synthetic material of the at least one housing section.
1. A steering device, comprising
a steering housing configured to receive and/or to hold at least one steering component, the steering housing including at least one housing section that is made from synthetic material; and
a sensor unit configured to detect at least one detection variable, wherein
the sensor unit is configured to detect a surface characteristic of the at least one steering component and/or to detect a foreign substance penetrating the steering housing, and
the sensor unit is embedded in the synthetic material of the at least one housing section, in a surface of the at least one housing section facing the at least one steering component, with the sensor unit facing the at least one steering component.
2. The steering device as claimed in claim 1 , further comprising:
a connector unit having at least one connecting line configured to contact the sensor unit, wherein the connecting line is integrated and/or embedded in the synthetic material of the housing section.
3. The steering device as claimed in claim 1 , wherein the at least one housing section is arranged in a region of a coupling gear and configured to connect an electric motor.
4. The steering device as claimed in claim 1 , wherein:
the steering housing has a base body, which is made at least to a large extent from the synthetic material; and
the housing section is designed in one piece with the base body.
5. The steering device as claimed in claim 1 , wherein:
the steering housing has a base body, which is made at least to a large extent from metal; and
the housing section is designed as a separate housing element that is connected to the base body in at least one of a non-positive locking manner, a positive locking manner, and a bonded manner.
6. The steering device as claimed in claim 5 , wherein:
the steering housing has the base body, which is made at least to the large extent from metal; and
the housing section is designed as the separate housing element that is connected to the base body in a non-positive-locking manner.
7. The steering device as claimed in claim 5 , wherein:
the steering housing has the base body, which is made at least to the large extent from metal; and
the housing section is designed as the separate housing element that is connected to the base body in a positive-locking manner.
8. The steering device as claimed in claim 5 , wherein:
the steering housing has the base body, which is made at least to the large extent from metal; and
the housing section is designed as the separate housing element that is connected to the base body in a bonded manner.
9. The steering device as claimed in claim 1 , wherein the sensor unit comprises at least one sensor element that is designed as a moisture sensor and/or a corrosion sensor and configured to detect the at least one detection variable.
10. A steering system having at least one steering device as claimed in claim 1 .
11. A method for producing a steering device as claimed in claim 1 , comprising:
producing the at least one housing section of the steering housing from the synthetic material;
integrating and/or embedding the sensor unit at least to a large extent in the synthetic material of the at least one housing section during the producing of the at least one housing section; and
configuring the sensor unit to detect at least one detection variable.
12. The method as claimed in claim 11 , wherein the at least one housing section is produced in an injection molding process and the synthetic material of the housing section is injection molded over the sensor unit.
13. The method as claimed in claim 11 , wherein the at least one housing section is produced and/or is connected to the sensor unit using a molded interconnect devices (MID) method.
