## Abstract

The invention relates to a hydraulic mount, including a hydraulic mount for mounting a motor vehicle engine on a vehicle body. In embodiments, the hydraulic mount includes: a hydraulic module with a support spring that supports a mount core, surrounds a working chamber, and is supported on an outer ring on which a cover is fixed, a compensation chamber which is separated from the working chamber by an intermediate plate and is delimited by a compensation membrane, wherein the compensation chamber and the working chamber are filled with a damping liquid and are connected with each other in a liquid-conducting manner via a damping channel arranged in the intermediate plate; and a housing accommodating the hydraulic module. In embodiments, the outer ring includes a radial projection with a rubber-lined axial abutment surface and a non-rubber-lined radial outer surface.

## Claims

### Claim at position 1

-9. (canceled)

### Claim 10

A hydraulic mount for mounting a motor vehicle engine on a vehicle body, comprising:
a hydraulic module with a support spring that supports a mount core, surrounds a working chamber, and is supported on an outer ring on which a cover is fixed, a compensation chamber which is separated from the working chamber by an intermediate plate and is delimited by a compensation membrane, wherein the compensation chamber and the working chamber are filled with a damping liquid and are connected with each other in a liquid-conducting manner via a damping channel arranged in the intermediate plate; and
a housing accommodating the hydraulic module,
wherein the outer ring has a radial projection, and the radial projection is provided with a rubber-lined axial abutment surface and a non-rubber-lined radial outer surface.

### Claim 11 (depends on 10)

The hydraulic mount according to claim 10, wherein the outer ring has an axially projecting flange with an annular groove for clipping in the cover.

### Claim 12 (depends on 10)

The hydraulic mount according to claim 10, wherein the housing reaching around the outer ring and a clip of the cover abuts against the axial abutment surface of the outer ring.

### Claim 13 (depends on 10)

The hydraulic mount according to claim 10, wherein the outer ring is made from a plastic.

### Claim 14 (depends on 10)

The hydraulic mount according to claim 10, wherein the outer ring is made from polyamide.

### Claim 15 (depends on 10)

The hydraulic mount according to claim 10, wherein a thickness of a rubber lining of the axial abutment surface is between 0.5 mm and 2 mm.

### Claim 16 (depends on 10)

The hydraulic mount according to claim 10, wherein a radial clearance is provided between the hydraulic module and the housing.

### Claim 17 (depends on 16)

The hydraulic mount according to claim 16, wherein the hydraulic module is fixed in the housing by means of a rotary movement.

### Claim 18 (depends on 10)

The hydraulic mount according to claim 10, wherein the hydraulic module is fixed to the housing by means of crimping.

### Claim 19

A method for assembly of a hydraulic mount comprising a pre-assembled hydraulic module and a housing accommodating the hydraulic module, the method comprising:
(a) inserting the pre-assembled hydraulic module into the housing in such a manner that bump stops can be guided through a connecting opening;
(b) rotating the hydraulic module relative to the housing by an installation angle so that the housing abuts against an axial abutment surface and reaches around an outer ring and a clip of a cover; and
(c) crimping the housing for fixing and securing the hydraulic module in the housing in an axial direction.
