Method of casting metal anti-shift collars for stabilizer bar
A method of processing a stabilizer bar assembly includes casting a metal anti-shift collar onto a prefabricated stabilizer bar. The metal anti-shift collar may be a zinc alloy, an aluminum alloy, or a magnesium alloy, for example.
1. A method of processing a stabilizer bar assembly, comprising:
casting a first metal anti-shift collar onto a prefabricated stabilizer bar, wherein the first metal anti-shift collar has a uniform diameter between terminal ends and includes a first collar surface for contacting a first bushing; and
casting a second metal anti-shift collar having a second collar surface for contacting the first bushing onto the prefabricated stabilizer bar.
2. The method as recited in claim 1 , including casting a zinc alloy as the first and second metal anti-shift collar.
3. The method as recited in claim 1 , including casting an aluminum alloy as the first and second metal anti-shift collar.
4. The method as recited in claim 1 , including casting a magnesium alloy as the first and second metal anti-shift collar.
5. The method as recited in claim 1 , including casting the first and second metal anti-shift collar in an annular shape.
6. The method as recited in claim 1 , including casting the first and second metal anti-shift collar onto a painted surface of the prefabricated stabilizer bar.
7. The method as recited in claim 1 , wherein the casting includes injecting molten metal into a cavity having a shape corresponding to at least one the metal anti-shift collars, solidifying the molten metal into at least one the metal anti-shift collars, and cooling the at least one metal anti-shift collar to cause shrinkage of the at least one metal anti-shift collar around the prefabricated stabilizer bar.
8. The method as recited in claim 1 , wherein the casting includes locating a section of the prefabricated stabilizer bar in a casting die having a cavity with a shape that corresponds to at least one of the metal anti-shift collars, closing the casting die around the section of the prefabricated stabilizer bar, and injecting a molten metal into the cavity.
9. The method as recited in claim 1 , wherein the terminal ends of the metal first anti-shift collar are axially opposing.
10. A method of processing a stabilizer bar assembly, comprising:
casting a first metal anti-shift collar and a second metal anti-shift collar onto a stabilizer bar, wherein the first metal anti-shift collar includes a first collar surface oriented to contact a first bushing and the second metal anti-shift collar includes a second collar surface oriented for contacting the first bushing.
11. The method as recited in claim 10 , wherein the first metal anti-shift collar is symmetric about a plane perpendicular to an axis of the stabilizer bar.
