A hydro bushing includes an outer pipe, an inner pipe disposed within the outer pipe and spaced apart from the outer pipe, an elastic body disposed between the outer pipe and the inner pipe and provided with a liquid chamber portion accommodating liquid therein, and a nozzle disposed between the outer pipe and the elastic body and including a stopper extending toward the liquid chamber portion such that a portion of an internal surface of the nozzle protrudes to be in contact with the liquid chamber portion. A contact end of the stopper is formed to have a surface corresponding to deformation of the elastic body caused by conical movement.

A void bush for a vehicle suspension includes: inside bumps formed in an inside stopper and outside bumps formed in an outside stopper. In particular, the inside bumps and the outside bumps are configured to cross perpendicularly to each other to allow the inside bumps and the outside bumps to be brought into point-contact with each other during behavior of the suspension. The inside bumps are not arranged in parallel to each other and the outside bumps are not arranged in parallel to each other. Accordingly, contact area between the inside bumps and the outside bumps is greatly reduced and contact abrasion positions therebetween are diversified so that durability and lifespan of the void bush are improved.
