Switching shaft for changing rotary position of e.g. switching flap, of intake system of internal combustion engine of motor vehicle, has functional and drive sections comprising non-circular cross-section wider than that of bearing section
Switching shaft for changing rotary position of e.g. switching flap, of intake system of internal combustion engine of motor vehicle, has functional and drive sections comprising non-circular cross-section wider than that of bearing section
The shaft (1) has a functional section (2) at which a component e.g. switching flap (6), is rotationally fixed, where the shaft is supported in a bearing block (7) of a bearing section with a round cross-section. A drive section is provided for fastening a rotary drive to the shaft. The functional section and the drive section have a non-circular cross-section, which is flat and is wider than the cross-section of the bearing section. The functional section is expanded over an elongate region of the component. An independent claim is also included for a method for producing a switching shaft.
