A wheel suspension system for a vehicle includes a mounting base and a striking base spaced from each other and moveable relative to each other along an arced line of motion. An insulator is coupled to and extends from the mounting base. The insulator is formed of an elastomeric material for compression between the mounting base and the striking base, i.e., the insulator is compressed along the arced line of motion between the mounting base and the striking base. The insulator includes a core portion extending along an axis and a ridge portion extending laterally from the core portion about the axis. The ridge portion extends circumferentially along the core portion at an acute angle relative to the base plane for guiding the compression of the insulator along the arced line of motion to uniformly distribute compressive forces within the insulator thereby increasing the durability and reliability of the insulator. |
