Coupling heads and stabiliser couplings for trailers and caravans
Secure connection between towing vehicle and trailer
The coupling securely connects the trailer or caravan to the towing vehicle. With a coupling head, the coupling mechanism encloses the towball of the vehicle's towbar. This connection transfers the towing and support forces that occur during driving.
Depending on the vehicle and application, different coupling systems are possible. While classic coupling heads primarily ensure a reliable mechanical link, stabiliser couplings provide an additional stabilising function. They reduce unwanted trailer movements and can particularly help to promote a smoother ride with a caravan.
AL-KO VT offers solutions for various braked and unbraked trailers as well as for caravans. Key factors when choosing a suitable coupling for your trailer include permissible gross weight, noseweight, drawbar connection and the type of coupling head arrangement.
Greater safety and control for your outfit
The benefits of a suitable coupling for your trailer
A reliable coupling must match the individual trailer and its technical requirements. Depending on the system, further advantages may be included in addition to a secure connection:
- Secure connection: Reliable transfer of forces between towing vehicle and trailer.
- Application-specific: Various versions for braked and unbraked trailers, as well as different weight classes.
- Increased driving stability: Stabiliser couplings reduce unwanted snaking and pitching movements.
- Smoother handling: Mechanical damping can help to stabilise the outfit, especially during caravan journeys.
- Range of installation options: Couplings are available for a variety of drawbar types, weights and noseweights.
How does a coupling head work?
Mechanical connection to the towing vehicle
The coupling head provides the mechanical connection between trailer and towing vehicle, transmitting both the towing and support forces that occur during driving. At the same time, it enables the necessary articulation of the outfit while on the move.
The correct coupling head for your needs depends on the specific trailer and its technical requirements. Decisive factors include the permissible gross weight, noseweight and type of drawbar connection. The coupling should always be selected to match both the trailer and the intended use.
What is a stabiliser coupling?
Additional stabilisation while driving
A stabiliser coupling not only ensures a safe connection between towing vehicle and trailer, but also actively supports the stability of the outfit while driving. Integrated friction pads counteract undesirable snaking and pitching movements, helping to keep the trailer smoothly on course.
In situations such as crosswinds, evasive manoeuvres or overtaking, trailer movements can be damped before they become more pronounced. This leads to a more stable ride and greater control over the trailer and vehicle combination.
With the AKS 3004, AL-KO VT offers a proven stabiliser coupling for caravans.
Frequently asked questions about coupling heads and stabiliser couplings
A coupling head connects the trailer drawbar to the towball of the towing vehicle. The coupling mechanism encloses the towball and transfers the towing and support forces between trailer and vehicle.
A coupling head provides the mechanical connection between towing vehicle and trailer. A stabiliser coupling also features friction pads that dampen snaking and pitching movements, improving the driving behaviour of the outfit.
Friction pads create a defined resistance on the towball against movements of the trailer. As a result, lateral snaking and pitching movements are particularly well dampened. The AKS 3004 uses this principle to reduce snaking motions.
The right coupling depends on the technical data and design of the trailer. Key factors to consider are the permissible gross weight, noseweight, type of drawbar connection and the corresponding coupling head arrangement.
Stabiliser couplings are mainly used where increased driving stability is required. The decisive factor is that the particular coupling is approved for the respective trailer in terms of weight, noseweight and connection.
There are different couplings for various drawbar types and trailer designs. Whether a specific coupling can be used on an existing trailer must be checked according to the technical requirements and the relevant product approval.
After hitching, the coupling must engage fully and securely on the towball. The operation and check indicators of the respective coupling and the instructions in the relevant manual are decisive here.
