SA3 Coupler with Energy Absorption
Freight applications are characterized by high strength requirements and rough conditions. Bulk material in particular may cause tenacious soiling, which drives specialized high-tech couplers out of the market. What is needed here is a simple and robust coupler that requires hardly any maintenance even in rough environment. Another aspect that becomes increasingly important is energy absorption. An update of the DIN EN 15227 will define crash worthiness requirements for locomotives for the first time.
SA3 couplers are the perfect example of all freight couplers. SA3 coupler heads are extremely robust and designed for heavy load applications, like those in coals or iron ore transportation.
Voith has developed an advanced, modular type of the SA3 coupler head. Integrated in air pipe connections, electric heads or sensors, the SA3 couplers allow a higher degree of automation which particularly is appealing for locomotives. Voith will show the first serial SA3 coupler with energy absorption worldwide.
AAR couplers are the standard for railcars in the American market. They transmit large mechanical forces and couple automatically. Connection of compressed air or electricity, however, is not a standard feature. Because of the large amount of play between the coupled heads, this is not easily accomplished. In the context of crash energy management, we have developed an energy-absorbing system that can also be used with AAR couplers. This provides greater functionality and safety.
The Type 55 Scharfenberg coupler has proven its flexibility and reliability in shunting applications for decades. It has been designed specifically for high loads in rough environments. Our coupler permits safe shunting and automatic assembly of trainsets. This means fewer accidents. An additional benefit - it is very easy to service and requires minimal maintenance.
