Powertrain mount
First Claim
1. A vibration isolator mount, comprising:
- a bracket member including a base portion having a pair of side wing portions extending from a pair of bends in said base portion and at least one pair of end wing portions extending from opposite ends of at least one of said base portion and said pair of side wing portions;
a core element including a body portion disposed between said pair of side wing portions and a mounting portion attached to said body portion; and
an elastomeric spring member disposed between said body portion of said core element and said pair of side wing portions of said bracket member, said at least one pair of end wing portions being bent toward said elastomeric spring member so as to oppose opposite ends of said spring member.

Abstract
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).
