Problems solved by technology

However, the solution known from this prior art has the disadvantage that it only makes sense for push operations
[0005] The disadvantage of the solution known from DE 3630360 A1 is that in particular two separate coil springs are always required, which make the tension / impact damping device long and complex
Furthermore, it is disadvantageous that the helical springs hit the housing undamped, causing loud noises when the load alternates

Embodiment approach

[0051] The structure of the damping mechanism 2 , which in this exemplary embodiment of the tension / impact damping device according to the invention is accommodated and formed at least partially in the damper housing 4 and which damps all The movement of the force transmission element 3 relative to the damper housing 4 when transmitting tension / compression is described.

[0052] Specifically, as only schematically shown in the figures, for this purpose, the damping mechanism has a spring system, which is particularly configured so that both the tensile force and the impact force are transmitted by pneumatic and / or hydraulic means. Can realize the function of cushioning and shock absorption.

[0053] For example, it is conceivable that the spring system of the damping mechanism 2 has a piston rod arrangement with a piston 6 and a cylinder arrangement 7, the piston 6 of the piston rod arrangement being movable relative to the cylinder arrangement 7, so that in this way The pist...

Abstract

The invention relates to a traction / impact device (1), in particular for medium buffer couplings of track-guided vehicles, in particular rail vehicles. The traction / impact device (1) comprises a damper housing (4), which is connected or connectable to a car body of the vehicle, and a force transmission element (3) for transferring tensile or impact forces onto the damper housing (4) Force transmission element (3) is movable relative to the damper housing (4) both in the pulling direction (A) and in the pushing direction (B). Furthermore, a damping mechanism (2) is provided, which is at least partially accommodated in the damper housing (4) and is designed to dampen the movement of the force transmission element relative to the damper housing (4) during traction / impact force transmission.

Description

technical field [0001] The invention relates to a tension / impact damping device, in particular a tension / impact damping device for a central damping coupler of a rail-mounted vehicle, in particular a rail vehicle. Background technique [0002] In particular, tension / impact damping arrangements for central damping couplers of rail vehicles are known from railway technology. Such a tension / impact device is used to absorb tension and compression forces during load switching, in particular in the pulling or pushing operation of long rail trains. This pull and impact dampener has been used for a long time. [0003] For example, DE 36 30 360 A1 discloses a tension / impact damper in which two friction springs are arranged tensioned relative to one another in a force balance. One of the two friction springs is designed for tension and the other friction spring is designed for compression. A friction spring under tension relaxes in the direction of pressure when pressure occurs. C...
