Shock absorber with one-piece fixing component
Damping element between two masses, consisting of a container tube, a piston mounted slidably therein in a damping medium, a piston rod connected to this piston, and a fastening part for connecting the container tube to the first of the two masses which are to be isolated from each other with respect to vibration, where the piston rod is connected to one of the masses. The fastening part, consisting of a stem and a fork and serving to connect the fastening part to the first mass, is manufactured as a one-piece component, preferably by forging.
1 . A shock absorber for installation between two masses, said shock absorber comprising:
a container tube containing a damping medium;
a base fixed to said container tube;
a piston arranged in said container tube for displacement in said damping medium;
a piston rod connected to said piston and being connectable to one of said masses; and
a fixing component comprising a stem and a fork which are made as a single piece, said stem being fixed to said base, said fork being connectable to the other of said masses.
2 . The shock absorber of claim 1 wherein the fixing component is a forged component.
3 . The shock absorber of claim 1 wherein the fixing component is made of steel.
4 . The shock absorber of claim 1 wherein the stem has a double-T cross-section.
5 . The shock absorber of claim 1 wherein the base comprises an extension which is received in the container tube and a shoulder which abuts the container tube.
6 . The shock absorber of claim 5 wherein the extension is received in the container tube in a press fit.
7 . The shock absorber of claim 1 wherein the base is welded to the container tube.
8 . The shock absorber of claim 1 wherein the fixing part consists of the stem and the fork.
9 . The shock absorber of claim 8 wherein the stem is welded to the base.
10 . The shock absorber of claim 8 wherein the base comprises a central bore, the stem being received in the central bore and welded to the base.
11 . The shock absorber of claim 8 wherein the base is formed as one piece with the container tube.
12 . The shock absorber of claim 8 wherein the base is formed with a cup which receives the stem.
13 . The shock absorber of claim 8 wherein the base is formed with a pin and the stem is formed with a bore which receives the pin.
14 . The shock absorber of claim 13 wherein the pin and the stem having mating threads.
