Abstract

A torque rod apparatus for a vehicle may include a damper supported at an outer circumference thereof by a lower frame of the vehicle, with a first hollow portion being axially formed in the damper, an inner core inserted into the first hollow portion of the damper, with a second hollow portion being axially formed in the inner core, an insert opening formed partially through the damper and the inner core in a radial direction to allow an interior of the inner core and an exterior of the damper to be bored through, and a linkage connected at a first end thereof to a drive unit, with a through hole formed in a second end thereof, the second end being inserted into the insert opening to allow the linkage to be integrally coupled to the lower frame of the vehicle and the inner core.

First claim

What is claimed is:

1. A torque rod apparatus for a vehicle, comprising:
a damper supported at an outer circumference thereof by a lower frame of the vehicle, with a first hollow portion being axially formed in the damper;
an inner core inserted into the first hollow portion of the damper, with a second hollow portion being axially formed in the inner core;
an insert opening formed partially through the damper and the inner core in a radial direction to allow an interior of the inner core and an exterior of the damper to be bored through; and
a linkage connected at a first end thereof to a drive unit, with a through hole formed in a second end thereof, the second end being inserted into the insert opening to allow the linkage to be integrally coupled to the lower frame of the vehicle and the inner core.

2. The torque rod apparatus as set forth in claim 1 , wherein the damper comprises an upper damper and a lower damper that are independently provided to be separate from each other, the upper and lower dampers being located to be spaced apart from each other by a predetermined interval.

3. The torque rod apparatus as set forth in claim 2 , wherein facing portions of the upper and lower dampers extend towards each other to be coupled in a single structure.

4. The torque rod apparatus as set forth in claim 3 , wherein the second end of the linkage is inserted to a position of a connected portion of the upper and lower dampers, which faces the second end of the linkage, thus defining a guide groove that allows the through hole to be aligned with the second hollow portion of the inner core.

5. The torque rod apparatus as set forth in claim 1 , wherein a plurality of recesses is formed on an outer circumference of the inner core, and a plurality of protrusions is formed on an inner circumference of the damper to engage with the recesses.

6. The torque rod apparatus as set forth in claim 1 , wherein the insert opening has a shape of a hole and is located in an axially central portion of the inner core.

7. The torque rod apparatus as set forth in claim 1 , wherein the insert opening is formed to allow the second end of the linkage to pass through the inner core.

8. The torque rod apparatus as set forth in claim 1 , wherein the insert opening is formed only in an insert-side direction of the linkage to prevent the second end of the linkage, inserted into the hollow portion of the inner core, from passing therethrough.

9. The torque rod apparatus as set forth in claim 2 , wherein an outer race is provided between the damper and the lower frame of the vehicle to surround the damper.

10. The torque rod apparatus as set forth in claim 9 , wherein an upper outer race and a lower outer race are provided, respectively, on an outer circumference of the upper damper and an outer circumference of the lower damper to surround the respective outer circumferences of the upper and lower dampers.

11. The torque rod apparatus as set forth in claim 10 , wherein a support casing is provided on the lower frame in such a way that an inner circumference of the support casing is formed according to a shape of the outer circumferences of the upper and lower dampers, so that the upper and lower dampers and the upper and lower outer races are press fitted therein, and, when the upper and lower dampers are press fitted into the support casing, the upper and lower dampers are compressed against each other, and a compressive force is generated on each of the upper and lower dampers in a radial direction thereof.

12. The torque rod apparatus as set forth in claim 1 , wherein the inner core has a shape of a cylinder in which the insert opening is formed, and the damper has a doughnut shape such that an inner circumference thereof comes into contact with an outer circumference of the inner core.

13. The torque rod apparatus as set forth in claim 1 , wherein the inner core and the linkage are integrally coupled to each other via a bolt passing through the through hole and the second hollow portion of the inner core.

14. The torque rod apparatus as set forth in claim 1 , wherein the inner core comprises an upper inner core and a lower inner core, the upper and lower inner cores being independently separated from each other to define a space therebetween, thus forming the insert opening.

15. The torque rod apparatus as set forth in claim 14 , wherein a bolt is provided to pass through the through hole and the second hollow portion of the inner core and thereby integrally couple them with each other.

16. The torque rod apparatus as set forth in claim 15 , wherein the lower inner core is coupled with the bolt in a single structure and the upper inner core is selectively coupled to the bolt.
