Damper assembly with accumulator
A method for assembling a damper assembly includes securing a damper interface to an external surface of a pressure tube. The method includes securing an accumulator interface to an external surface of an accumulator tube. The method includes, after the damper interface is secured to the pressure tube and the accumulator interface is secured to the accumulator tube, securing the pressure tube to the accumulator tube by press fitting the damper interface to the accumulator interface.
1. A method for assembling a damper assembly, the method comprising:
securing a damper interface to an external surface of a pressure tube;
securing an accumulator interface to an external surface of an accumulator tube; and
then, after securing the damper interface to the pressure tube and securing the accumulator interface to the accumulator tube, securing the pressure tube to the accumulator tube by press fitting the damper interface to the accumulator interface.
2. The method of claim 1 , further comprising welding the damper interface to the accumulator interface after press fitting the damper interface on the accumulator interface.
3. The method of claim 2 , wherein the press fitting provides sufficient securement to maintain a position of the pressure tube relative to the accumulator tube while welding the damper interface to the accumulator interface.
4. The method of claim 2 , wherein welding the damper interface to the accumulator interface includes laser welding.
5. The method of claim 1 , wherein the damper interface and the accumulator interface each include a conical interface surface, and press fitting the damper interface on the accumulator interface includes pressing the conical interface surfaces into abutment.
6. The method of claim 1 , wherein the press fitting includes an interference fit between the damper interface and the accumulator interface.
7. The method of claim 1 , wherein securing the damper interface to the external surface of the pressure tube includes securing a damper cap to the damper interface and to the external surface of the pressure tube.
8. The method of claim 7 , wherein the damper cap is secured to the damper interface before the damper cap is secured to the pressure tube.
9. The method of claim 8 , wherein securing the damper cap to the external surface of the pressure tube includes welding the damper cap to the external surface of the pressure tube.
10. The method of claim 9 , wherein securing the damper cap to the damper interface includes welding the damper cap to the damper interface.
