Hydraulic bushing with springs in series

A hydraulic bushing forms a mount between a first component and a second component by including a first spring portion connected between a core and an inner support structure and a second spring portion surrounding the inner support structure. The first spring portion is formed of rubber and defines hydraulic fluid cavities and a fluid channel extending between the cavities, while the second spring portion is formed of microcellular polyurethane. The first spring portion and the second spring portion are located so they operate in series with one another. In this way, vibrations of a load transferred through the hydraulic bushing can be damped at a predetermined low frequency by the rubber with hydraulic fluid cavities, while still allowing for isolating of higher frequencies by the microcellular polyurethane.
