Electronic steering system with electric pump

Electronic steering system with electric pump

VSE Advanced Steering is an electrohydraulic steering system with an electrically driven pump. This pump is mounted on the trailer. The truck supplies electrical power for the steering system via a 24 V connection. In some cases the system is equipped with batteries, which are charged via the connection to the truck.

THE SYSTEM

THE SYSTEM

Because a trailer with VSE Advanced Steering has its own energy supply, it can easily be switched from one truck to another. All the truck needs is a suitable 24 V connection, such as a NATO socket.

For long trailers or trailers that have to make many steering movements in a short time, the system can be equipped with batteries. These would be maintenance-free AGM batteries that have very low self-discharge, which means they will still be well-charged even if the trailer has not been used for a long time. The energy supply for VSE Advanced Steering can optionally be used for other consumers at standstill, such as hydraulic ramps.

TECHNICAL POSSIBILITIES

TECHNICAL POSSIBILITIES

  • With electric pump on the trailer
  • Various versions with 1, 2 or 3 Ackermann-steered axles
  • Comes with a standard stainless steel system locker. In addition, a steering cylinder and angle sensor are supplied for each steered axle, plus a kingpin and various cables. Customisation is possible
  • With VSE Steering a steering angle of up to 45 degrees can be achieved
  • The system can be supplied with an axle included
  • The system weighs between 160 and 470 kg
  • Customised software
  • Can be used with any brand of axle and an axle load of up to 10 tonnes

ENERGY SUPPLY

ENERGY SUPPLY

If the system is not equipped with batteries, the electrically driven pump is powered by the truck’s batteries. Important condition: The truck must be equipped with an alternator with a continuously available surplus capacity of at least 20 A (intercity deployment). The truck’s batteries and the VSE system locker must be connected with a power cable, possibly in combination with a spiral cable.

If the system is equipped with batteries, the batteries will have to be charged by the truck’s alternator. It is important that the truck is equipped with an alternator having a continuously available extra capacity of at least 20 A (intercity deployment).

INSTALLATION

INSTALLATION

  • Installation of the special kingpin with sensor. This is just as simple as installing one without a sensor.
  • Fitting the ready-to-use stainless steel system locker, supplied by VSE.
  • Fitting one or more Ackermann-steered axles with a VSE steering cylinder.
  • Making the electrical and hydraulic connections between the system locker, kingpin and axles.
  • Calibration of the VSE system via the intuitive VSE diagnostic program. No bleeding required!

SAFETY

SAFETY

The steering is gradually reduced above 25 km/h, axles are rigid above 55 km/h. This ensures optimum stability!

The system is self-correcting, so hitting an obstacle such as a kerb will not cause tracking misalignment. This is not possible with mechanical and hydraulic systems.

When VSE Steering is switched off, the wheels will always be locked in the straight-ahead position. In the case of mechanical or hydraulic systems, when problems occur it is often no longer possible to drive.
