## Abstract

The invention is directed to a spring strut support mount, including a damper element and a mount housing having a first and a second housing member, wherein the housing members can be threadably engaged by a thread so as to encompass the damping element. The housing members have a detent arrangement which permits a screwing action but prevents a loosening of the thread connection. The invention provides for improving a spring strut support mount such that the housing members cannot loosen from one another during operation. The housing members have a detent arrangement which permits a screwing action but prevents a loosening of the thread connection.

## Claims

### Claim 1

A spring strut support mount including a housing having first and second housing members that can be screwed together in an axial direction to form a threaded connection, the spring strut support mount further comprising:
a detent arrangement permitting a screwing action in said axial direction and preventing a loosening of said threaded connection in a second direction of rotation opposite said axial direction of rotation;
said first and second housing members conjointly defining an interface;
said detent arrangement being disposed at said interface and being a two-part detent arrangement including a first part on one of said first and second housing members and a second part on an other one of said first and second housing members;
said first part including a first periphery at said interface and a lug having a predetermined peripheral shape and said lug being disposed on said first periphery directed toward said second part;
said second part including a second periphery at said interface and having first and second grooves formed in said second periphery arranged one behind an other along said second periphery with said first and second grooves being acted upon by said lug in response to a rotation of said housing members relative to each other;
said first groove being defined by a first flank having a first slope and a second flank having a second slope opposite to said first slope;
said second groove being a detent groove defining a shape corresponding at least in part to said peripheral shape of said lug;
said first and second parts of said two-part detent arrangement being matched to each other so as to cause said lug to successively contact and engage said first and second flanks and then slip into said detent groove as said first and second housing members are rotated relative to each other in said axial direction of rotation when assembling the spring strut support mount; and,
said detent groove and said lug conjointly defining a steep slope interface so as to permanently prevent the rotation of said first and second housing members relative to each other in said second direction of rotation thereby preventing a loosening of the threaded connection.

### Claim 2 (depends on 1)

The spring strut support mount of claim 1, wherein the first and second housing members include a damping element clamped between the first housing member and the second housing member.

### Claim 3 (depends on 1)

The spring strut support mount of claim 1, wherein the first housing member and the second housing member have an elasticity that permits movement of the first housing member and the second housing member in the axial direction.

### Claim 4 (depends on 1)

The spring strut support mount of claim 1, wherein the lug has a steep slope in the axial direction and a second slope in the second direction.

### Claim 5

In a spring strut support mount including a housing having first and second housing members that can be screwed together in an axial direction to form a threaded connection, a detent arrangement permitting a screwing action in said axial direction of rotation and preventing a loosening of said threaded connection in a second direction of rotation opposite said axial direction of rotation; the detent arrangement comprising:
an interface conjointly defined by said first and second housing members;
a first part on one of said first and second housing members and a second part on an other one of said first and second housing members;
said first part including a first periphery at said interface and a lug having a predetermined peripheral shape and said lug being disposed on said first periphery directed toward said second part;
said second part including a second periphery at said interface and having first and second grooves formed in said second periphery arranged one behind an other along said second periphery with said first and second grooves being acted upon by said lug in response to a rotation of said housing members relative to each other;
said first groove being defined by a first flank having a first slope corresponding to said thread pitch and a second flank having a second slope opposite to said first slope;
said second groove being a detent groove defining a shape corresponding at least in part to said peripheral shape of said lug;
said first and second parts of said two-part detent arrangement being matched to each other so as to cause said lug to successively contact and engage said first and second flanks and then slip into said detent groove as said first and second housing members are rotated relative to each other in said axial direction of rotation when assembling the spring strut support mount; and,
said detent groove and said lug conjointly defining a steep slope interface so as to permanently prevent the rotation of said first and second housing members relative to each other in said second direction of rotation thereby preventing a loosening of the threaded connection.
