"Shock absorber"

For this filing, the priority will be Czechoslovakian Patent application PV 7958-67 dated November 9, 1967 to claim taken.

The invention deals with a cylindrical shock absorber for Disc couplings τοη Masohinenanlagen, for hanging hook τοη Leaf springs and for semi-axles in motor vehicles.

So far, such dampers were made of solid rubber, leather or swing metal.

Due to the effect of atmospheric influences, oil and extreme stress, the rubber from which the dampers are recovered is devalued in the course of the tent, and by replacing the damaged, used dampers with new ones, machines and vehicles create countless stagnation conditions. In the case of anti-vibration mounts, in addition to aging, there is also mechanical wear and tear and damage to the surface of the outer metal sleeve.

You object after the invention is based on these disadvantages to eliminate. The solution to this problem is based according to the invention on a shock absorber made of elastic tough material, which consists of a cylindrical body having a central passage «are in this cylindrical body resilient segments formed in that a number of parallel and axially extending openings to the central passage in the cylindrical body is connected to the central passage through spaces. These radially formed Gaps divide the cylindrical body into individual resilient segments.

Shock absorbers designed in this way, made of elastic tough material, allows constant pressure compensation with minimal wear and tear and much smaller More susceptibility to defects than can be achieved with dampers in the previous version.

Disc clutch exactly «to be delimited. This arrangement makes the assembly and disassembly of the damper much easier, because it is possible to manufacture the damper with a smaller Durohmesser, and the necessary preload, i.e. the required Enlargement of the diameter of the cylindrical body in the opening of the elastic disc coupling by actuating the Adjust the screw nut on the drive pin. The delimitation of the clearance of the cylindrical body (the degree of pre-tensioning) can be followed with the naked eye.

Another advantage of the shock absorber according to the invention is the resistance to surface wear, to mechanical stress and to the effects of atmospheric influences and mineral oils, all of these properties of the damper resulting in a much longer shelf life have consequence.

They are mainly used for disc clutches on heavy machinery such as excavators, truck cranes, diesel Locomotives, compressors, and normal motor vehicles were worn to blow off steps and vadial dmok during aioppv ± ngen of the Ireleteiles and ven vibrations uni. Vibrations on the Connection point serves two bodies.

Pig. 1 shows a longitudinal section through the damper

and
FIG. 2 shows a cross section through the plane AwA in FIG. 1.

The damper 1 has a cylindrical body 1 which has a number of openings 3 which run parallel to its axis. These openings 3 or only some of them are connected radially to the central passage 2 by intermediate spaces 4 which subdivide the central part of the damper between the central passage 2 and the openings 3 into resilient segments 5.

The openings 3 can be round or geometrical others have shaped cross-sections. In each individual segment 5 there can be one or more openings.

The body of the damper 1 is made of plastic, a.B. made of polyamide or any other material that has the same technological properties.
