RU95102850A - Upper support of automobile suspension spring strut guide - Google Patents

Abstract

FIELD: transport engineering; vehicle suspensions. SUBSTANCE: upper support 1 of suspension spring strut guide has outer housing 2 and inner housing 4 cured to outer housing through layer of ring rubber insert 3. Bearing 5 is installed and rolled in inner housing 4. Groove is made in lower portion of inner race 6 of bearing 5 at side of its inner surface. Upper cup 8 of spring 9 is fitted-in flush with surface by its support-and-centering flange 7. Ring-shaped rubber joint 10 with bushing 11 cured to its inner wall is press-fitted in seat formed by inner surface of inner race 6 and inner surface of support-and-centering flange 7 of upper cup 8 of spring 9. Shank 12 of rod 13 is secured in bushing 11. Support rebound stroke limiter 14 is mounted on shank 12 and pressed to upper end of joint 10. Lower end of joint 10 and lower end of bushing 11 thrust against washer 15 installed on step 16 made on rod 13. Compression buffer 17 is installed on rod 13 below washer 15. EFFECT: improved rigidity characteristics of support when fully laden automobiles operates under heavy road conditions (at maximum strokes of wheel suspension). 1 cl, 1 dwg

Claims (1)

The invention relates to a transport mechanical engineering, namely to car suspensions. The objective of the invention is to improve the stiffness characteristics of the support, especially when operating a car with its full load in difficult road conditions (i.e., at maximum travels of the wheel suspension). The upper support 1 of the guide spring strut of the vehicle suspension bracket contains an outer casing 2, to which an inner casing 4 with a bearing 5 mounted and rolled in it 5 is vulcanized through a layer of an annular rubber insert 3. A groove is made in the lower part of the inner ring 6 of the bearing 5 from its inner surface, into which the upper cup 8 of the spring 9 is flush-pressed by the support-centering flange 7. The support center is formed into the seat formed by the inner surface of the inner ring 6 and the inner surface the flange 7 of the upper cup 8 of the spring 9, a ring-shaped rubber hinge 10 is pressed in with a sleeve 11 vulcanized to its inner wall, in which a shank 12 of the rod 13 is fixed with its upper end pressed against the upper end of the hinge 10, the limiter of the support rebound 14. The lower the end face of the hinge 10 and the lower end of the sleeve 11 are based on the washer 15 mounted on the protrusion 16, made on the rod 13. And below the washer 15 on the rod 13 is mounted a compression buffer 17.
