초록 ▼

A throttle body for an automobile includes a throttle shaft defining a rotational axis. The throttle shaft includes deformable members integrally formed about an exterior surface of the throttle shaft. A housing includes a bore. The throttle shaft extends through the bore with the deformable member partially-located within the bore. A bearing includes an inner surface and an outer surface. The bearing inner surface forms a press-fit connection with the deformable members to substantially prevent movement between the throttle shaft and the bearing in a direction parallel to the rotational axis.

What is claimed is: 1. A method of forming a throttle shaft for a throttle body of an automobile, said method comprising the steps of: providing a shaft member defining a rotational axis; providing a forming tool having a split die having a plurality of contact points and uncompressed regions; inserting said shaft member in said forming tool; compressing said forming tool against said shaft member for displacing material to said uncompressed regions for forming a plurality of protruding splines; press-fitting said shaft member into a bearing of said throttle body; measuring a press-fit force applied to said shaft member for inserting said shaft member into said bearing; providing feedback indicative of said press-fit force applied to said shaft member; and adjusting said compression force of said forming tool applied to said shaft member in response to said feedback. 2. The method of claim 1 wherein said forming tool forms said plurality of splines of at least a minimum axial length. 3. The method of claim 1 wherein said forming tool applies a predetermined compression force to said shaft member for forming said plurality of protruding splines. 4. The method of claim 1 wherein said step of compressing said forming tool is restricted by hard stops mounted to said forming tool, said hard stops limiting a travel of said forming tool.
