TwinStroke buffers |
|
TheTwinStroke buffer is a sophisticated regenerative energy absorption system based on the gas-hydraulic working principle.
It consists of
- A casing
- A piston transmitting the tension and compression loads
- Gas and nitrogen chamber
The damping effect is achieved by
- Compression of the gas volume in the nitrogen chambers (static)
- Throttled overflow of oil between the oil chambers (dynamic)
Benefits
- Reliable absorption of the tension and compression loads (with-out the need of using a friction spring)
- Reduced size
- Low weight
- Reduced cost of purchase
- Reduced number of wearing parts
- Freedom of maintenance for at least 8 years
- Reduced life cycle costs
- Increased energy absorption
(dynamic energy absorption on tension even in case of load change stress)
Working principle
The TwinStroke buffer is the first gas-hydraulic buffer in the world that is able to dampen both tension and compression loads without the need of using additional absorption features.
Depending on the tension and compression stress, a piston moves forward and backward within a certrain stroke range thus compressing the gas volumes. The pressure produced in the oil chambers by the effect of the piston is compensated in such a manner that the oil is by-passed into an adjoining chamber through over-flow channels. By this way any stress produced along the buffer's longitudinal axis is immmediately compensated and wear is minimised. Shocks are dampened and impact loads are absorbed. |
