Abstract

A mount to couple a transmission to a vehicle body includes a first body with at least one first body connector, and a second body with at least one coupler connected to the first body and which includes a damping material arranged to damp vibrations between the first body and second body. A retainer is carried by the first body and has a portion that overlaps part of the second body to prevent separation of the second body from the first body in a first state of the retainer. The retainer is broken or removed from the first body in a second state to permit separation of the second body from the first body, and the retainer breaks or is removed from the first body under a force less than the force needed to break or remove the at least one first body connector from the vehicle body.

First claim

What is claimed is:

1. A mount to couple a transmission to a vehicle body, comprising:
a first body having at least one first body connector adapted to be coupled to the vehicle body to retain the first body relative to the vehicle body;
a second body having at least one coupler that is connected to the first body and which includes a damping material arranged to damp vibrations between the first body and second body;
and a retainer carried by the first body and having a portion that overlaps part of the second body to prevent separation of the second body from the first body in a first state of the retainer, and wherein the retainer is broken or removed from the first body in a second state to permit separation of the second body from the first body, and wherein the retainer breaks or is removed from the first body under a force less than the force needed to break or remove the at least one first body connector from the vehicle body.

2. The mount of claim 1 , wherein the retainer includes a main body coupled to the first body and wherein the portion that overlaps part of the second body is defined by a flange extending outwardly from the main body.

3. The mount of claim 2 wherein the flange is defined by a washer and the main body includes a fastener having a head that overlies part of the washer and a threaded shank that extends through an opening in the washer and is coupled to the first body.

4. The mount of claim 1 wherein the retainer includes a threaded shank and the first body includes a threaded bore in which the threaded shank is received.

5. The mount of claim 4 wherein the threaded bore is a blind bore.

6. The mount of claim 1 wherein multiple first body connectors are provided and wherein the retainer is coaxial with one of the first body connectors.

7. The mount of claim 1 wherein the first body includes a first end with a first one of the at least one first body connectors coupled to the first body at the first end, the first body includes a second end with a second one of the at least one first body connectors coupled the first body at the second end, and with a third one of the at least one first body connectors located between the first end and the second end.

8. The mount of claim 7 wherein the at least one coupler includes a first coupler connected to the first body adjacent to the first end and a second coupler connected to the first body adjacent to the second end and wherein the retainer is located between the first coupler and second coupler.

9. The mount of claim 1 wherein the first body includes two opposed side surfaces and the at least one coupler includes a body formed over the opposed side surfaces and clamping the coupler to the first body to resist separation of the second body from the first body.

10. The mount of claim 9 wherein the damping material is provided between the coupler body and the first body.

11. The mount of claim 8 wherein the first coupler includes a body formed over opposed side surfaces of a portion of the first body closer to the first end than to the second end, and the second coupler includes a body formed over opposed side surfaces of a portion of the first body closer to the second end than to the first end.

12. The mount of claim 1 wherein the retainer breaks or is removed from the first body under a force greater than the force needed to separate the at least one coupler from the first body.

13. A mount to couple a transmission to a vehicle body, comprising:
a first body adapted to be coupled to the vehicle body;
a second body having multiple couplers that are mechanically connected to the first body without an adhesive or chemical bond between them, and wherein the couplers include a damping material arranged to damp vibrations between the first body and second body; and
a retainer secured to the first body and having a portion that overlaps part of the second body to permit limited relative movement between the second body and the first body and to prevent separation of the second body from the first body in a first state of the retainer, and wherein the retainer is broken or removed from the first body in a second state to permit separation of the second body from the first body, and wherein the retainer breaks or is removed from the first body under a force greater than the force needed to separate the couplers from the first body.

14. The mount of claim 13 which also includes one or more first body connectors adapted to connect the first body to the vehicle body and wherein the retainer breaks or is removed from the first body under a force less than the force needed to break the first body connectors or separate the first body connectors from the vehicle body.

15. The mount of claim 13 wherein the couplers include a coupler body that is pressed onto the first body.

16. The mount of claim 15 wherein spaced apart portions of the coupler are bent around portions of the first body.

17. The mount of claim 15 wherein the coupler body is bonded to or embedded in the damping material of the second body.

18. The mount of claim 13 wherein the first body includes a threaded opening and the retainer includes a threaded portion received in the threaded opening.

19. The mount of claim 13 which also includes one or more second body connectors adapted to connect the second body to the transmission and wherein the retainer breaks or is removed from the first body under a force less than the force needed to break the second body connectors or separate the second body connectors from the transmission.

20. The mount of claim 14 wherein the retainer is separate from each of the first body connectors.
