Product description

The P110 telescopic hydraulic damper is designed for damping sprung masses on track vehicles: it enables reliable operation at temperatures from -40ºC to +50ºC up to a speed of 0.5m.s-1.

Technical parameters

Main parameters:

Damper diameter:
110 mm
Maximum damping force:
1 9 kN
Stroke range:
70-120 mm
Attenuation characteristics:
with bounding box

This damper was developed as a replacement for the friction dampers. Its main application is the primary chassis suspension of vehicles for passenger traffic. The working flow system consists of flow nozzles and plate (planchette) valves. Its simplicity is a prerequisite for good operational reliability.

By adjusting the flow system inside the steamer, different damping forces can be achieved. The most commonly used damping characteristic is 16.16 in kN.s.m-1. A maximum of 45.45 can be set.

The damping characteristics are set in such a way that the damping effects are limited at higher speeds. This ensures that the damper is protected against mechanical stress.
The Pl 1 0 damper is designed for use on vehicles where a large working stroke with minimum installation dimensions is required. This was achieved by relieving the main damper parts. The damper has a subtle design and its force load is limited to a maximum of 19 kN. The P110 dampers are manufactured in standard stroke lengths of 70 to 120 mm (10 mm each). The internal arrangement means that the P110 damper only operates in a vertical position with a maximum inclination of 30°.

ST-OS offers a wide range of end brackets for vehicles. As a standard, dampers are supplied with the piston rod mounted via rubber plates and with the lower mounting via rubber plates or by means of rubber buffers with a sleeve or with a pin.
