    Connecting any application

      Perfect Match

      Our couplers and articulations are ideally matched to their application. They permit automatic and simultaneous coupling of mechanical, pneumatic and electrical components. We also provide solutions for connecting vehicles with different coupler types of coupling heights.

      Solutions for Light Rails and Trams

      Scharfenberg Couplers

      Type 330

      The Type 330 is used primarily in light rail and tram applications. It is small yet strong. Locating the electrical coupling underneath at the head is also possible. The coupler can transmit a buff load of 800 kN and a draft load of up to 600 kN.

      Type 430/530

      Its especially compact and lightweight construction makes the Type 430/530 Scharfenberg coupler the ideal type of coupler for low-floor trams and monorails. As a folding coupler, it also fits behind front covers. It can transmit compressive and tensile forces of up to 300 kN. The type 530 was mainly developed for the Eastern German market and is compatible to the TGL couplers that used to be very common there.

      Adapter Couplers

      Modular adapter coupler

      Adapter couplers are used when vehicles have different types of couplers or coupling heights, e.g. when shunting and towing. Until now, this frequently required special designs. The new, modular adapter coupler separates the different components into two separate heads and an adapter that forms the step. The two separate heads can also be connected to one another directly. This makes it possible to combine coupler heads of any kind and at different heights easily into an adapter coupler.

      Albert Couplers

      Albert couplers are used primarily on vehicles that are coupled only infrequently. The connection is made by means of pins. The coupler's drawbar can be provided with a folding knuckle (joint) which allows the uncoupled drawbar to be folded under the car.

      Solutions for Metros

      Scharfenberg Couplers

      Typ 35

      The Type 35 is especially well-suited for vehicles without a compressed-air system. On these fully electrified vehicles, the coupler can transmit a buff load of 1,300 kN and a draft load of up to 850 kN. The Type 35 is used primarily in light rail and tram, metro and regional transportation applications.  

      Typ 330

      The Type 330 is used primarily in light rail and tram applications. It is small yet strong. Locating the electrical coupling underneath at the head is also possible. The coupler can transmit a buff load of 800 kN and a draft load of up to 600 kN.

      Semi-Permanent Couplers

      Semi-permanent coupler with air couplings, electrical coupling, impact absorber and gangway support

      Semi-Permanent Coupler Principle

      Scharfenberg semi-permanent couplers provide secure and safe connections within a trainset. Since coupling and uncoupling do not take place during normal operation, automatic operation is not necessary. Semi-permanent couplers can be equipped with impact-absorbing elements as well as with electrical and pneumatic couplings. 

      Semi-permanent coupler with anti-climbing feature

      For the first time, a semi-permanent coupler for metro vehicles assumes anti-climbing function. Contrary to conventional systems, this coupler has a stabilising effect even before any overriding occurs. The dimensions of the coupler remain unaffected by this new technology.

       

      Anti-Climbing Feature: Working Principle

      During a train crash or heavy impact, the longitudinal forces are converted into vertical swerving movements leading to an overriding of the cars once a critical momentum has been exceeded. This may cause the wagon to disconnect from its Jacobs bogie and damage softer structures.

      The anti-climbing feature has been designed to prevent this overriding right from the start. To do so, it uses a simple, yet highly efficient principle: The rear end of the coupler shank features a special geometry. As soon as the reversible stroke of the coupler has been utilised, this geometry interlocks with the bearing bracket, building a counter-momentum that holds the wagons down.

      Additional energy absorbing components of the semi-permanent coupler, e.g. deformation tubes or hydrostatic dampers, convert kinetic energy and help to keep the load on a controllable level.

The new, modular adapter coupler separates the different components into two separate heads and an adapter that forms the step. The two separate heads can also be connected to one another directly. This makes it possible to combine coupler heads of any kind and at different heights easily into an adapter coupler.

      Additional Couplers

      Wedgelock coupler

      The operating principle of the automatic Wedgelock coupler is based on mechanical wedging of the coupler locks. During mechanical coupling, the coupler hooks engage automatically. They are then locked in position upon pneumatic actuation of the wedges by the vehicle operator. Safe and full coupling is maintained even in the event of air failure. Coupling of air and electrical lines takes place simultaneously with mechanical coupling. The simple and proven design ensures a compact, reliable product.

      Tomlinson coupler

      The operating principle of the automatic Tomlinson coupler is similar to that of the Wedgelock coupler. During coupling, the hooks on the two coupler heads engage one another and are held in position by springs. Different hook sizes are used, depending on the application. Because of the small amount of play between the coupler heads, the Tomlinson coupler can also be provided with electrical and air couplings. Couplers of this type are common on metro rail cars in the USA.

      SA3 Coupler with Energy Absorption

      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. The coupler can be perfectly adapted to customer requirements and combined with Voith energy absorption systems. Furthermore, automation features can be integrated.

      AAR couplers

      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.

      Type GF


      The Type GF automatic coupler is very common in Belgium and Switzerland. During coupling, the conical elements engage their their funnel-shaped counterparts in the mating coupler and are locked in place. The couplers can be provided with air and electrical couplings and transmit a buff load of 1,500 kN and a draft load of 1,000 kN in the standard design.

      Solutions for Locomotives

      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.
