■ Elastic bearing

The invention relates to an elastic bearing for the lowering cylinder of magnetic rail brakes for rail vehicles, which is arranged at the end of the cylinder and / or the piston rod and from between the vehicle and the cylinder or brake magnet and Piston rod arranged elastic parts consists.

Bearings in which elastic elements are interposed, were known from DE-PS 97 / * 92o and AT-PS 175 599, but either a layer of rubber is pressed between the two parts or a metal-rubber-metal element is used. From DE-OS 21 43 o76 is a storage for a lowering cylinder known, which is characterized by the double cone shape of the elastic layer pressed between the parts to be stored is. However, these known bearings have the disadvantage that the rubber parts and the assembly must have special shapes requires some care so that the right rubber parts are in the right place. Can also be adjacent to each other When installed, surfaces execute movements relative to one another, which leads to the destruction of the rubber elements.

The present invention is therefore based on the object of avoiding the disadvantages of the known bearings, and in particular to provide a simply constructed warehouse using commercially available parts that still have all the advantages of the known Has camp, especially with regard to the freedom of movement.

The solution to the problem is that each bearing consists of two rubber rings arranged on one part (vehicle or cylinder or brake magnet or piston rod) and lying between abutments attached to this part, between which a flange arranged on the other part extends, with between there is a clearance between the inner periphery of the flange and the other part.

A lying on the part is advantageous between the abutments Sleeve o.a. provided and the distance is between the outer circumference the sleeve and the inner circumference of the flange.

The advantage of the invention is that as rubber parts Commercially available rubber rings with, for example, a rectangular or square cross-section can be used, so that a Mixing up the two rubber rings present in a bearing does not lead to the bearing becoming unusable. Still leaves such a bearing movements of the two parts to each other in all axes, whereby by the size of the bias of the Rubber rings the bearing is harder or softer adjustable «

In the drawing is an example embodiment of the Invention shown, according to which the bearing 1 consists of two formed in the form of discs abutments 2 and 3, between which have two rubber rings if with a rectangular cross-section. A flange 5 extends between the two rubber rings If, the inner circumference 6 a distance 8 from the part 7 or the over this part 7 has pushed sleeve 11. Above and below of the flange 5, surfaces 12 running essentially concentrically are provided, the flange 5 and the surfaces 12 Part of a mounting plate 9 are. On the end of the part 7, which is cylindrical, there is a nut 1o, which rests against the upper abutment 2.

To assemble the bearing 1, the lower abutment disk 3 is first pushed over the part 7 until this disk 3 rests against the collar 13 of the part 7. Then the sleeve 11 is inserted, through which the lower rubber ring if is then pressed in. Then the flange 5 is placed on the lower rubber ring k <and the upper rubber ring if inserted, on which the upper abutment 2 is then placed and the rubber rings if \ are pressed together with the nut 1o until the two abutments 2 and at the two ends the sleeve 11 rest, as shown in the drawing. The mother Io is then secured in the usual way. That

Part 7 is part of the piston rod of the Abeenk cylinder or is attached to the cylinder base in a manner known per se or consists of one piece with the cylinder base, so that After assembling the bearing 1 of the actuating cylinder by attaching the plate 9 to the vehicle and attaching the lower Plate 9 is brought into its working position on the brake magnet. Due to the two bearings, the brake magnet can be opposite to the Actuating cylinder as well as moving in all three axes in relation to the vehicle (together with the actuating cylinder) and thereby the on rail joints etc., when driving in curves etc. adapt to any shifts that occur * The brake magnets are therefore supported on the rail surface in all states.

The camp also has the further advantage of being different Length of the sleeve 11, the size of the compression of the rubber rings can be changed so that the bearing all external conditions can be adapted, which a different Require hardness of the camp "

If the rubber rings are given an approximately oval cross-section _t, this can be selected so that the rubber rings in the compressed state have approximately the rectangular cross-section shown in the drawing, which is essential for the effectiveness of the bearing.

Instead of the sleeve 11 one can also use the part 7 approximately at the same height of the upper end of the sleeve screw on another collar on which the upper abutment 2 rests when the nut 1o is tightened launches, whereby the distance between the two abutments 2 and 3 is set to the desired level.

The height of the concentric surfaces 12 is known in a known manner chosen so that the plate 9 also occurs in the largest Deflections does not touch one of the abutments.

Of course, rings can also be used instead of the rubber rings 4 made of other elastic materials can be used, with the damping effect inherent in some elastic plastics can take effect, the part 7 can also be something other than round Have cross-section, thereby adjusting the abutment opening a stooping around the longitudinal axis is possible.
