Abstract
A spring rear isolator has a base to couple the isolator with a suspension module. A spring seat, coupled with the base, has an index pilot hub to receive a pig tail end of a coil spring. The index pilot hub has an overall circular cylindrical shape with a lobe that peripherally extends from a portion of the cylinder. The lobe fixes position of the coil spring in the spring seat. The index pilot hub extends axially from the base into a second revolution of the coil spring.
Claims18
A spring rear isolator comprising:
- a base for coupling the isolator with a suspension;
- a spring seat including a plate configured to mate with the base and having an axially outwardly extending index pilot hub for receiving a pig tail end of a coil spring, the index pilot hub having an overall circular cylindrical shaped cylinder with a lobe extending from a peripheral portion of the cylinder and defining a stop that is configured to abut a terminal end of the pig tail end,
- wherein the lobe fixes a position of the coil spring in the spring seat;
- and
- the index pilot hub axially outwardly extending from the base through a second revolution of the coil spring and defining a height relative to the plate, and the stop extends along an entirety of the height of the index pilot hub.
