Abstract

A suspension strut fork that has an upper portion which is constructed in an integral, materially uniform manner in the form of a suspension strut receiving member. Members and fork arms protrude therefrom in an integral, materially uniform manner. A gap is provided between the members. Via this gap, the members can be moved toward each other so that a resilient and/or damper element which is arranged in the suspension strut receiving member is securely clamped.

First claim

The invention claimed is:

1. A method of producing a suspension strut fork, wherein the method comprises:
processing a tubular member using cutting technology into two semi-finished products, wherein each of the two semi-finished products has a cylindrical upper portion and two parallel members protruding from the upper portion, and
for a semi-finished product of the two semi-finished products,
producing an outer fold on the upper portion by reducing a diameter of the upper portion, to obtain the two parallel members protruding from the upper portion,
separating the two parallel members, and
bending the two parallel members.

2. The method according to claim 1 , further comprising producing the tubular member by extrusion from a light metal material.

3. The method according to claim 1 , wherein the tubular member comprises a circular cross-section.

4. The method according to claim 1 , wherein the processing of the two parallel members using the bending comprises at least one of
shaping the two parallel members over a longitudinal extent thereof, or
shaping a cross-section of the two parallel members.

5. The method according to claim 1 , further comprising reprocessing, in a machining manner, faces of the two parallel members which face each other.

6. The method according to claim 1 , further comprising reprocessing individual faces or holes of the suspension strut fork.

7. A method of producing a suspension strut fork, the method comprising:
cutting a tubular member into two semi-finished products, wherein each of the two semi-finished products has a cylindrical upper portion and two arms protruding from the upper portion, and
for a semi-finished product of the two semi-finished products,
producing an outer fold on the upper portion by reducing a diameter of the upper portion, to obtain two parallel members protruding from the upper portion,
separating the two parallel members, and
bending the arms into fork arms, to obtain the suspension strut fork.
