SPRING STRUT SUPPORT MOUNT

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

1. A spring strut support mount including a damping element and a housing having first and second housing members mutually threadably engageable to form a threaded connection and encompass the damping element, the spring strut support mount further comprising: a detent arrangement permitting a screwing action in a first circumferential direction of rotation and preventing a loosening of said threaded connection in a second circumferential direction of rotation opposite said first circumferential direction of rotation.

2. The spring strut support mount of claim 1, wherein: said first and second housing members conjointly define an interface; said detent arrangement is disposed at said interface and is a two-part detent arrangement including a first part on said first housing member and a second part on said second housing member; said first part includes a first periphery at said interface and has a lug disposed on said first periphery directed into the interior of said housing; said second part includes a second periphery at said interface and has a groove formed in said second periphery directed radially inwardly with said groove corresponding to said lug of said first part of said detent arrangement; said first and second parts of said two-part detent arrangement are matched to each other so as to cause said lug of said first part to engage in said groove of said second part when assembling said housing members; and, said groove has at one side thereof an increasing slope rising from inside to outside viewed in one of said first and second circumferential directions.

3. The spring strut support mount of claim 2, wherein: said first part includes a plurality of said lugs disposed on said first periphery in spaced relationship to each other; said second part includes a plurality of said grooves formed in said second periphery corresponding to respective ones of said lugs of said first part; and, each of said grooves, on one side thereof, includes said increasing slope rising from inside to outside viewed in said one of said first and second circumferential directions.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0009] The invention will now be described with reference to the single FIGURE of the drawing (FIG. 1) which shows a lower section of a spring strut support mount 1 in a partial section.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0010] The spring strut support mount 1 has an upper housing member 2 and a lower housing member 3. The housing members 2 and 3 can be screwed together in an axial direction and include a damping element (not visible here) which is clamped between the housing members 2 and 3. The upper housing member 2 has a detent profile 5 on its lower end 4.

[0011] The lower housing member 3 has a further detent profile 7 on its upper end 6. The detent profile 7 exhibits substantially a lug 8, which faces toward the upper housing member 2 and which has a slope 9 and a steep face 10.

[0012] The detent profile 5 of the upper housing member 2 has a first sloping flank 11, which corresponds to the gradient of the thread (not shown here). The sloping flank 11 is followed by a slope 12, the gradient of which is opposite to that of the sloping flank 11. There subsequently follows a detent groove 13, the shape of which corresponds to the lug 8 of the detent profile 7.

[0013] During the screwing movement of the housing members 2 and 3, the housing members 2 and 3 move toward one another. Here, the lug 8 can come into contact with the sloping flank 11 until it abuts with its slope 9 against the slope 12. During a further screwing movement, the slopes 9 and 12 slide on one another, which is possible owing to elasticity of the housing members 2 and 3 and of the play, which is to be maintained exactly, in the thread turns. At the end of the screwing movement, the lug 8 slides into the corresponding detent groove 13. Owing to the shape of the detent groove 13 and the steep face 10 of the lug 8, a backward rotation of the housing member 2 relative to the housing member 3 is no longer possible, which prevents an inadvertent opening of the spring strut support mount.

[0014] It is understood that the foregoing description is that of the preferred embodiments of the invention and that various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
