Abstract

Disclosed is a side-assembly-type transmission mount, in which a powertrain-rotation-preventing unit is mounted to a case, which is coupled to the upper portion of a transmission bracket, thereby preventing a powertrain from falling when a bolt is fractured. The powertrain-rotation-preventing unit includes a rotation-preventing pipe configured to allow the bolt to be inserted therethrough and to have rotation-preventing protrusions protruding from the upper and lower portions thereof, first rotation-preventing recesses formed in a core so as to have shapes corresponding to the rotation-preventing protrusions on the rotation-preventing pipe, and second rotation-preventing recesses formed in a space formed in a transmission support bracket. The rotation-preventing protrusions on the rotation-preventing pipe are inserted into the first and second rotation-preventing recesses formed in the core and the transmission support bracket.

First claim

What is claimed is:

1 . A side-assembly-type transmission mount comprising:
a core inserted into an insulator and having a through-hole formed therethrough; a plate stopper coupled to the core, and having a though-hole; a case accommodating the core and the insulator; a bolt formed to be longer than the case and to be inserted through the through-hole formed in the core and the plate stopper from a side so as to protrude outside the case; a transmission support bracket having an upper portion directly coupled to the bolt protruding outside the case and a lower portion coupled to a transmission; a rotation-preventing cage and a rotation-preventing nut, mounted to the upper portion of the transmission support bracket to mesh with the bolt; and a powertrain-rotation-preventing unit mounted between the rotation-preventing cage and the core.

2 . The side-assembly-type transmission mount according to claim 1 , wherein the powertrain-rotation-preventing unit comprises:
a rotation-preventing pipe configured to allow the bolt to be inserted therethrough and to have rotation-preventing protrusions protruding therefrom; first rotation-preventing recesses formed in the core having shapes corresponding to the shape of the rotation-preventing protrusions on the rotation-preventing pipe; and second rotation-preventing recesses formed in a space formed in the transmission support bracket.

3 . The side-assembly-type transmission mount according to claim 2 , wherein the rotation-preventing pipe is inserted through the core in an interference-fit manner and is coupled to the transmission support bracket in a sliding manner.

4 . The side-assembly-type transmission mount according to claim 2 , wherein the rotation-preventing pipe further comprises a slanted surface formed at an end thereof so as to facilitate assembly of the rotation-preventing pipe with the transmission support bracket.

5 . The side-assembly-type transmission mount according to claim 1 , wherein the rotation-preventing nut is a square nut, and the transmission support bracket has therein a space formed to receive the rotation-preventing nut, the space being formed in a square shape.

6 . The side-assembly-type transmission mount according to claim 1 , wherein the case is cylindrical.

7 . The side-assembly-type transmission mount according to claim one wherein the through-hole in the core extends in a longitudinal direction.

8 . The side-assembly-type transmission mount according to claim 2 , wherein the rotation-preventing protrusions on the rotation-preventing pipe are inserted into the first and second rotation-preventing recesses formed in the core and the transmission support bracket.
