Definitions

• the invention relates to a sleeve buffer according to the preamble
• Such a sleeve buffer is from DE-PS 462
• the known sleeve buffers have a buffer housing
• the pestle Component and a plunger movable relative to the guide sleeve front buffer plate as a movable component.
• the buffer housing arranged either a spring element or a spring damper element.
• Part of the total length can be used as spring travel to shorten the buffer. In the event of a strong shock load that exceeds the energy absorption capacity of the buffer, it can cause the buffer to penetrate
• DE-PS 462 539 is already a sleeve buffer for rail vehicles
• buffer housing which consists of a fixed base plate attached to the support structure, one attached to the base plate
• Movement member exists.
• the movement member is guided by the guide sleeve during its displacement movement.
• the known sleeve buffer has a force transmission member in the form of a spring
• Wall of the movement member is weakened at one point, which means that a controlled when the movement member strikes the base plate
• Movement member shortens the guide sleeve by the deformation path
• the object of the invention is to design a sleeve buffer of the type mentioned at the outset in such a way that with significantly increased energy consumption the additional shortening of the buffer is of the order of magnitude of the spring travel and the displacement of the

• Inner wall is slidable.
• the end face of the movement member 13 which protrudes from the guide sleeve 12 is provided with a buffer plate 14
• the movement member 13 and the guide sleeve 12 need one to limit the friction and to protect against self-locking by tilting
• Has sleeve buffer
• ring springs for example ring springs, elastomer springs, rubber springs with or without parallel arranged
• the coupling member 23 is designed so that when a limit load is exceeded e.g. shears off at a predetermined breaking point and thus allows the two spring elements 21, 22 to slide into one another telescopically without transmitting longitudinal forces.
• the coupling member 23 has in the example shown ( Figures 1 to 3)
