POWERTRAIN MOUNT

WIPO Patent Application WO2005015050

A3

A vibration isolation mount (10) is provided including a bracket member (12) including a base portion (18) having a pair of side wing portions (24, 26) extending from a pair of bends in the base portion (18). At least one pair of end wing portions (28, 30) extend from opposite ends of the bracket member (12). A core element (14) including a body portion (46) is disposed between the pair of side wing portions (24, 26). An elastomeric spring member (16) is disposed between the body portion of the core element (14) and the pair of side wing portions of the bracket member (12). The at least one pair of end wing portions (28, 30) are bent towards the elastomeric spring member (16) so as to oppose opposite ends of the spring member so as to provide a lateral travel restrictor for the elastomeric spring member (16) without the necessity of additional components. According to yet another aspect of the present invention, a travel restrictor pin (52) is provided extending between the pair of end wing portions (28, 30) and through an opening in the body portion (46) of the core element (14). The travel restrictor pin (52) provides additional longitudinal travel restriction in order to limit the amount of stresses applied to the elastomeric spring member (16).
