Abstract

An upper mounting system for a MacPherson strut includes a shock absorber mount and an air spring mount. The air spring mount is disposed coaxially around the shock absorber mount. A curved spherical interface of the air spring mount permits pivotal movement of the air spring such that it maintains a coaxial relationship with the shock absorber. The curved spherical interface also provides a seal for sealing the gas chamber of the air spring.
