Electric Power Steering uses mainly Koyo and NSK units for our conversions, the same as used in modern cars. Both brands are Japanese. The advantage of these units is that various safety features are built-in, making it easy to obtain T?V approval. If the electronics fail, the car will steer exactly as before the conversion. Moreover, in the improbable case that this should happen, the assistance will fade gradually, like an old tube radio (after 1 to 2 seconds); Therefore, the power steering assistance decreases gently and there is no startle reaction at the wheel if the unit were to fail when driving through a low speed turn. In the unlikely event that an electric motor should jam, a magnetic clutch in the transmission ensures that the steering will not seize and make the car uncontrollable. We use new units, but some kits are produced with remanufactured units for power steering kits we designed 10-15 years ago and new units are no longer available. Our company and the products we produce are certified by the German T?V Nord, a guarantee for a safe, high quality product.
The manufacturer develops a metal mounting frame for each type of car. For the prototype, this frame is bent, drilled and welded by hand (just the frame, not the car!) after which a CAD drawing of the final design is made. Then the frame is laser cut and set at the correct angles. The final frame then has several adjustment options to accommodate the large tolerances in classic cars.The input and output shafts have the original external spline joints at the ends, allowing the use of the original steering wheel and steering rack. The other side of the shafts have internal splines that connect to the power steering unit. This ensures a reliable, safe connection at all times. The ECU (Electronic Control Unit) and torsion sensor, which controls the amount of assistance, are modified by us to perfectly match the steering character of the car for which we develop the kit. Modern ECUs work with CAN (Controller Area Network) bus data signals that are not present in a classic car. For this purpose, the manufacturer has developed an interface that mimics the engine speed, speed signal and steering angle from the CAN-bus and thus controls the ECU. The speed signal can be realized artificially, via GPS or by a speed adapter on the odometer. What makes this Electric Power Steering special is the fact that we produce a completely new steering column (in most cases) that replaces the original. The strength of the torsion rod is selected to best suit the vehicle it is designed for and we have our own unique method to reduce the internal drag of the power steering unit, which greatly improves the steering feel and self-centering properties of the power steering unit.
