Connecting element for releasably and vibration damping connection of a first component to a second component
View Patent ↗A connecting element for separably connecting a first component to a second component in a vibration damping fashion and, optionally, for compensating tolerances between the first and the second component in a compensation direction, wherein the connecting element comprises a damping ring with an inner sleeve that can be fixed in the first component, as well as a spring element with an oblong hole arranged therein, and wherein a retaining bolt can be snapped between two spring surfaces of the spring element essentially parallel to a snap-in direction. The inner sleeve comprises an insert which comprises either a cylindrical bore or an oblong hole. Alternatively, the connecting element can be respectively realized for producing connections between the components with or without tolerance compensation by selecting the appropriate insert that comprises either a cylindrical bore or an oblong hole.
1. A connecting element for separably connecting a first component to a second component in a vibration damping fashion, wherein the connecting element comprises:
a damping ring,
an inner sleeve, and
a spring element with an oblong spring element hole,
wherein the damping ring can be fixed in the first component,
wherein a retaining bolt can be snapped between a first and a second spring surfaces of the spring element essentially parallel to a snap-in direction,
wherein the inner sleeve comprises an insert; and
wherein the insert is exchangeable;
wherein the insert comprises a bore with circular dimensions for realizing a connection without tolerance compensation or oblong hole dimensions for realizing a connection with tolerance compensation;
wherein a base plate of the spring element is rigidly connected in contact with a safety plate and an upper collar of the inner sleeve is arranged between the base plate of the spring element and the safety plate; and
wherein the spring element is fixed on the safety plate.
2. The connecting element of claim 1 , wherein the insert is manufactured from a plastic material.
3. The connecting element of claim 1 ,
wherein the insert is rigidly connected to the inner sleeve, by the means of bonding, vulcanization, pressing or clamping therein.
4. The connecting element of claim 1 , wherein the damping ring comprises a peripheral outer recess in which recess an outer sleeve with a retaining collar is arranged in order to create a contact surface for the connecting element in an edge region of a mounting bore within the first component, and wherein the damping ring is held in the mounting bore by a locking ring.
5. The connecting element of claim 4 , wherein the outer sleeve is adapted for being rigidly connected to the damping ring, particularly by bonding, pressing, clamping or vulcanizing.
6. The connecting element of claim 1 , wherein the spring element is realized with the first and second spring surfaces that are located essentially parallel to and opposite of one another.
7. The connecting element of claim 1 ,
wherein the inner sleeve has an essentially annular cross-sectional geometry with an inner sleeve diameter.
8. The connecting element of claim 1 ,
wherein an outside diameter of the safety plate is larger than a mounting bore diameter.
9. The connecting element of claim 1 , wherein the first and the second spring surface comprise first and second snap-in tabs that are respectively directed toward one another and can be snapped into corresponding recesses on both sides of the retaining bolt.
10. The connecting element of claim 1 , wherein the inner sleeve is adapted for being rigidly connected to the damping ring particularly by bonding, pressing, clamping or vulcanizing.
11. The connecting element of claim 1 ,
wherein the spring element is riveted, welded or bonded to the safety plate.
