Abstract
An improved and tight package vibration isolator assembly increases the strength of the mount structure without compromising the efficiency of the damping features. An exo-skeleton bracket design provides a rigid structural strength able to withstand extreme loads. The bracket also allows forces to bypass the fluid components of the damping assembly that are otherwise subject to potential passage of forces therethrough. The exo-skeleton bracket provides a stiff structure that substantially surrounds the damping assembly. Tuning of the assembly is also simplified through use of a travel limiter assembly, the cross-section of which may change in shape, or characteristics of a surrounding resilient sleeve selectively altered, to tune the damping characteristics of the damping assembly.
Claims20
A vibration isolator assembly interposed between associated first and second surfaces of a vehicle, the assembly comprising:
- a structural exo-skeleton bracket dimensioned to extend between the associated first and second surfaces for transferring forces therethrough, the bracket including means for securing the bracket to one of the associated first and second surfaces;
- and
- a damping assembly received in the exo-skeleton that is protected from the transferred forces by the exo-skeleton bracket, the damping assembly including means for securing the damping assembly to the other of the associated first and second surfaces.
