Abstract
A body connection and a method of manufacturing the body connection is disclosed. A body connecting sleeve is formed in two parts from a spacer sleeve arranged in an axle auxiliary frame and from a body connecting sleeve which is coupled only to the upper shell of the axle auxiliary frame and substantially corresponds to the length of the centering extension. The body connecting sleeve is coupled exclusively in a form-fitting manner to the upper shell.
Claims11
A body connection for an axle auxiliary frame of a motor vehicle, the body connection comprising:
- an axle auxiliary frame including a hollow two-part shell component having an upper shell and a lower shell, and
- a body connecting sleeve protruding in relation to the upper shell with a centering extension in the direction of the body,
- wherein the body connecting sleeve includes two parts such that
- a spacer sleeve is arranged between the upper shell and the lower shell of the axle auxiliary frame, and
- an upper body connecting sleeve which is separate from the spacer sleeve, is coupled in a form-fitting manner only to the upper shell,
- wherein the body connecting sleeve has a collar protruding in a radially encircling manner, and
- wherein the collar has an outer diameter which is identical to or greater than an outer diameter of the spacer sleeve.
A method of manufacturing a body connection,
- the body connection comprising:
- an axle auxiliary frame including a hollow two-part shell component having an upper shell and a lower shell, and
- a body connecting sleeve protruding in relation to the upper shell with a centering extension in the direction of the body,
- wherein the body connecting sleeve includes two parts such that
- a spacer sleeve is arranged between the upper shell and the lower shell of the axle auxiliary frame, and
- an upper body connecting sleeve, which is separate from the spacer sleeve, is coupled in a form-fitting manner only to the upper shell,
- wherein the body connecting sleeve has a collar protruding in a radially encircling manner, and
- wherein the collar has an outer diameter which is identical to or greater than an outer diameter of the spacer sleeve,
- the method comprising:
- producing the upper shell as a sheet-metal formed component in a forming die,
- introducing the body connecting sleeve into the upper shell in the forming die, and
- coupling the body connecting sleeve to the upper shell in a form-fitting manner.
