Abstract

A mount (100) for an exhaust system includes a support (110) configured for being fixed to a component of the exhaust system (200) or an underbody of a vehicle, and a mounting mandrel supported by the support (110). The support (110) has a first plate (111) and a second plate (112) spaced apart from the first plate (111). The first plate (111) and the second plate (112) each include a fixing section (113, 114) for fixing the support (110) to a component of the exhaust system (200) or an underbody of a vehicle. The first plate (111) and the second plate (112) each includes an opening (115, 116). The mounting mandrel (120) includes a first section (121) configured for penetrating through an exhaust system rubber (300). The mounting mandrel (120) has a second section (122) that passes through the openings (115, 116) in the first and second plates (111, 112).

First claim

What is claimed is:

1. A mount for an exhaust system, the mount comprising:
a support configured for being fixed to a component of the exhaust system or to an underbody of a vehicle, the support comprising a first plate and a second plate spaced apart from the first plate, each of the first plate and the second plate comprising a fixing section for fixing the support to the component of the exhaust system or to the underbody of a vehicle, each of the first plate and the second plate comprising an opening; and
a mounting mandrel supported by the support, the mounting mandrel comprising a first section configured to penetrate through an exhaust system rubber, and a second section in which the mounting mandrel penetrates the opening in the first plate and the opening of the second plate, the opening in the first plate and the opening in the second plate having a diameter that is by at least 10% greater than a diameter of the mounting mandrel at a region of the mounting mandrel, the region of the mounting mandrel being located at a position, where the mounting mandrel penetrates through a respective opening, wherein the mounting mandrel comprises two spaced apart metal disks in the second section, each of the metal disks surrounding the mounting mandrel, the opening in the first plate being offset from the opening in the second plate in an axial direction with respect to a longitudinal axis of the mounting mandrel, wherein at least one of:
the first plate and the second plate of the support are located between the two metal disks; and
each one of the first plate and the second plate of the support is located directly adjacent to one of the two metal disks.

2. A mount according to claim 1 , wherein the opening in the first plate and the opening in the second plate of the support have a diameter that is by not more than 150% greater than the diameter of the mounting mandrel at the region of the mounting mandrel, the region of the mounting mandrel being located at a position, where the mounting mandrel penetrates through the respective opening.

3. The mount according to claim 1 , wherein the mounting mandrel is welded to the first plate and the second plate of the support at the regions of the mounting mandrel, the regions of the mounting mandrel being located at positions of the opening in the first plate and the opening in the second plate.

4. The mount according to claim 1 , wherein one of the metal disks located closer to the first section of the mounting mandrel than another one of the metal disks is formed integrally with the mounting mandrel.

5. The mount according to claim 1 , wherein one or more of:
at least one of the metal disks is joined to the mounting mandrel by a frictional connection;
at least one of the metal disks is joined to the mounting mandrel by a welded connection;
at least one of the metal disks is joined to the mounting mandrel by a brazed connection; and
at least one of the metal disks is joined to the mounting mandrel by an adhesive bonding connection.

6. The mount according to claim 1 , wherein each of the metal disks is welded to one of the first plate and the second plate, each of the metal disks being located adjacent to one of the first plate and the second plate.

7. The mount according to claim 1 , wherein a hole normal of the opening in the first plate and a hole normal of the opening in the second plate are spaced apart, the mounting mandrel extending straight in the first section and the mounting mandrel extending S-shaped in the second section.

8. The mount according to claim 1 , wherein one of:
the first plate is parallel to the second plate; and
the first plate and the second plate are in planes that confine an angle of less than 20°.

9. The mount according to claim 1 , wherein one of:
the mounting mandrel and the opening in the first plate and the opening in the second plate have a circular cross-section;
the mounting mandrel and the opening in the first plate and the opening in the second plate have an oval cross-section;
the mounting mandrel and the opening in the first plate and the opening in the second plate have a triangular cross-section;
the mounting mandrel and the opening in the first plate and the opening in the second plate have a tetragonal cross-section; and
the mounting mandrel and the opening in the first plate and the opening in the second plate have a polygonal cross-section.

10. The mount according to claim 1 , wherein the mounting mandrel comprises two spaced apart protrusions in the first section, one of the protrusions being arranged farther from the second section of the mounting mandrel than another one of the protrusions, the one of the protrusions arranged farther from the second section of the mounting mandrel comprising a ramp at a side of the one of the protrusions facing away from the second section of the mounting mandrel.

11. The mount according to claim 1 , wherein the support is formed in one piece from a metal sheet, and a connecting section interconnects the first plate and the second plate of the support.

12. The mount according to claim 1 , wherein the fixing section of the first plate of the support is oriented parallel to the first plate, the first plate being located closer to the first section of the mounting mandrel than the second plate of the support, wherein the fixing section of the second plate of the support confines together with the second plate an angle of more than 60° or an angle of more than 80° or an angle of 90° , said second plate being spaced farther away from the first section of the mounting mandrel than the first plate of the support.

13. The mount according to claim 1 , wherein the fixing section of the first plate of the support is spaced apart at least as twice as far from the opening in the first plate than the fixing section of the second plate of the support is spaced apart from the opening in the second plate, whereby the first plate is located closer to the first section of the mounting mandrel than the second plate of the support.

14. A mount for an exhaust system, the mount comprising:
a support configured for being fixed to a component of the exhaust system or to an underbody of a vehicle, the support comprising a first plate and a second plate spaced apart from the first plate, the first plate comprising a first plate fixing section for fixing the support to the component of the exhaust system or to the underbody of a vehicle, the first plate further comprising a first plate opening, the second plate comprising a second plate fixing section for fixing the support to the component of the exhaust system or to the underbody of a vehicle, the second plate further comprising a second plate opening; and
a mounting mandrel supported by the support, the mounting mandrel comprising a first section configured to extend through an exhaust system rubber, and said mounting mandrel comprising a second section, one portion of the second section arranged at or adjacent to the first plate opening and another portion of the second section being arranged at or adjacent to the second plate opening, the first plate opening and the second plate opening having a diameter that is by at least 10% greater than a diameter of each of the one portion of the second section of the mounting mandrel and the another portion of the second section of the mounting mandrel, wherein the mounting mandrel comprises two spaced apart metal disks in the second section, each of the metal disks surrounding the mounting mandrel, the opening in the first plate being offset from the opening in the second plate in an axial direction with respect to a longitudinal axis of the
