The main patent relates to a permanently lubricated * "bearing in which the shaft link moves especially long" in the socket link and "smell the socket link and skin * £ song an ouaoi link is arranged, with both the ÖUEnai | li _e d ale as well as at least one of the two mentioned Storage surface which has a bearing surface and provides space or space for a lubricant to the bearing surfaces pouring out onto one another.

According to the invention, this becomes even further as a result better that the Raus sur Aufnmhae des Sohralenaittele In an era eleven ouianl link aagabrachter, by Stete is formed by separate Auanebaangen. Hach one further SrfindusgeaerkBai, these webs are rounded off

Other features, parts of the gate and possibilities of grazing The invention can be found in the enclosed sections 28-33 and in the description of exemplary embodiments below.

When the Chuualarael has been cast and before it is inserted between the inner and outer metal bearing members, its separating webs 53 and the load-absorbing and abtrageadec hips 23 (S ¹ Xg. 31) have been rounded off

pre-assembled facility, this represents the presence of lubricant between each of the load bearing rings and bars and the load bearing member during operation secure.

«Run the guinmi sleeve ready>; is mounted, then there is a Fit with oversize between the rings and the webs and the metal body. The size of this fit oversize should be such that the total; itatisehe burden and the Maximum value of the dynamic Laet that can be expected from the unit is not the consequence ·: has that some part of a. load-bearing ring or web of its touching one Tearing away pipe section. With other varieties, it is important that alls load support ring odev -stege with the tubular member to each Time to stay connected. Load changes change the area of contact between rubber and ear, and that change depends on the supply of fresh lubricant to those parts of the rubber that come into contact with the tubular member are. The webs 23 prevent or prevent a free circulation of 4es viacose lubricant all around the ansel link. This (correction is important in installations in which the bearing bush is intended to have a certain Period of time not being used, like one Automobile that is not used for several months. With such users; it is important to have a large number of distributed relaxation abocies in the practice area of the to have sleeved G-ummiglledeo, each ^ * district © ine Recess 25 delimited in order to take viscous lubricants and hold on. You dl. ”Pig. 30, 31, 32 and 33 sstigen, different forms can be provided.

One of the main problems solved by the invention described above, particularly in connection with mife applications in cars, the problem is "stiction".

909811/0536

"Suction ^M is the highly undesirable tendency to stick an unslminated rubber limb to another limb against which it is pressed * which leads to correspondingly increased frictional forces when the rubber is to be pulled away from the other limb. In short, aan finds a high static Frictional force occurs when attempting to tear the rubber sleeve away from the metal bin. "Stiction ™ causes early wear of rubber on" metal bearings in which relative movement between the rubber surface and the metal surface is desired. In order to reduce or eliminate this "stiction", a large number of lubricating recesses 25 are distributed around the rubber member, and all load-bearing surfaces are rounded (in their unloaded state) to facilitate the lubricant, the load-bearing effects of the ring 53 and the To reach ridges or ribs. Even after assembly, it's like Pig. 34 shows advisable that the loaded bars or rings retain their rounded shape somewhat.

Another factor that can be used to reduce or eliminate the term The "stiction" thing that matters is the stiffness of the Gunmie. The stiffer the rubber »the more it is torn away the result of better lubrication and lower stiction ^ -JBrscbeinunj. Jedooh must have the stiffness of the rubber in the Rings and bars in a corresponding relationship to the thickness of the Rubber "stand" around which forms the bottom of the recesses to prevent the rubber in the rings and ridges from getting underneath The load acts on the recesses to an extent flows that it drives out the lubricant. The thinner the gumni that forms the bottom of the recesses, the heavier it is it is for the Rinp, - and otege ^ umnii, ia the pockets to flow, and to drive out the Schm.ierniitt.fr I "Ss has therefore shown that -äaü to prefer i:; t, the ßodon of the recesses like this

au make thin as possible because 4 ^e thinner the rubber is, the faster the tearing away takes place. Bach these general instructions can be an inexpensive, im. In general, produce permanent, dense-on-metal bearings that have a long life, low friction and a low Peder constant.

Its further development of the bearing according to the invention is in? Ig. 28, the outer socket member is shown as two different ones Has diameter 26 and 27 ^ Eia such bearing can s.B. in the field of automobile end face support systems to be dispensed. Furthermore, a rubber bearing of the type shown in FIG. 29 The type shown can be used «It has a sealing Iistabstützring 28 between the two end rings 29 from £ * and this intermediate ring 28 is adjacent to the inequality conveyor @ .H The outer bearing links are arranged in the inner bolt arm to prevent the viscous lubricant from flowing off migrates at one end of the storage area to the other end.
