JEFA TRANSMISSION STEERING SYSTEMS

The Transmission Steering System (TSS) is based on the same principals as a rack and pinion system with a direct and solid connection to the rudder. The rotation of the wheel is transferred to a push pull movement via gearbox and levers. With the TSS system, the distance between the wheel to the rudder shaft can be much larger and the routing more complex, which makes it the ideal system for center cockpit sailboats. Via torque tubes, universal joints, and bevel gearboxes, the rotation is transmitted to the reduction gearbox next to the rudder shaft. The reduction gearbox transfers the rotating movement into a push and pull movement on the tiller lever. As all rotating parts use roller bearings, and the system can be easily back driven by the rudder, the steering system provides the same precision and feel as a tiller steered boat, but with a helm that can be placed away from the rudder.
