Abstract

A transmission mount for a vehicle may include a bracket which accommodates an insulator having an external core coupled with an internal core, and includes an upper housing that covers an upper portion of the insulator, and a plate that supports a lower portion of the insulator; and the external core which includes, based on the inserted internal core, a lower portion, an upper portion, both lateral portions, both bridge portions that support a body of the external core, and a lower main stopper formed on an upper surface of the plate, in which a space portion is formed in a body of the external core wherein a strut, which protrudes from a rear surface of an upper housing of the bracket, is inserted into the space portion, and internal wall surfaces of the space portion come into contact with an upper portion, a lower portion, and a front portion of the strut, respectively.

First claim

1 . A transmission mount for a vehicle, comprising:
a bracket which accommodates an insulator having an external core coupled with an internal core, and includes an upper housing that covers an upper portion of the insulator, and a plate that supports a lower portion of the insulator; and the external core which includes, based on the inserted internal core, a lower portion, an upper portion, both lateral portions, both bridge portions that support a body of the external core, and a lower main stopper formed on an upper surface of the plate, wherein a space portion is formed in a body of the external core wherein a strut, which protrudes from a rear surface of an upper housing of the bracket, is configured to be inserted into the space portion, and internal wall surfaces of the space portion contact with an upper portion, a lower portion, and a front portion of the strut, respectively, and wherein a lower auxiliary stopper is formed to protrude upward from an upper surface of the lower portion of the external core.

2 . The transmission mount of claim 1 , wherein the upper housing includes an upper surface which covers the upper portion of the insulator, a rear surface which covers a rear surface of the insulator, and lateral surfaces which cover left and right surfaces of the insulator, respectively.

3 . (canceled)

4 . The transmission mount of claim 1 , wherein an upper auxiliary stopper is formed to protrude downward from a bottom surface of the upper portion of the external core.

5 . The transmission mount of claim 1 , wherein lateral auxiliary stoppers are formed in a direction toward a center from internal walls of the lateral portions of the external core.

6 . The transmission mount of claim 1 , wherein an internal wall surface auxiliary stopper is formed toward an end surface of the strut from an internal wall surface of the space portion formed in the external core which faces the end surface of the strut.
