  • Dynamic pierce point centering spring seat
    Patent number: 7624973
    Abstract: A shock absorber assembly includes a coil spring that reacts between first and second spring seats. The first spring seat is fixed to a shock cylinder and the second spring seat is fixed to a rod that is slidably received within the shock cylinder. An isolator is positioned between an end coil of the spring and at least one of the first and second spring seats. The isolator comprises an annular ring that defines a cavity that is at least partially filled with fluid. The isolator evenly distributes non-centered spring end forces through the fluid to reduce the effects of side load forces.

  • Static pierce point centering spring seat
    Publication number: 20070158925
    Abstract: A shock absorber assembly includes a coil spring that reacts between first and second spring seats. The first spring seat is fixed to a shock cylinder and the second spring support is fixed to a rod that is slidably received within the shock cylinder. At least one of the first and second spring seats comprises an adjustable two-pierce spring seat. First and second spring seat pieces are initially movable relative to each other to achieve a desired spring pierce point location for a selected operational position. Once the first and second spring seat pieces are adjusted to a desired position, the first and second spring seat pieces are permanently attached to each other.
