The function of the complete rod on the vehicle can be described as long tie-rod and short tie-rod in the systems that are defined as rigid axle system.

Long tie-rod
Long tie-rod transmits the actions transmitted by short tie-rod to the axle located on the other side. Long tie-road connected to selector lever and right/left rods transmits the action of selector level to the rods. It is used for transmission of steering actions to the front wheels and for optimum handling. Long tie-rod provides a precise direction and secure driving. A centrally located part allows for optimal adjustment of both wheels.

Short tie rod
Short tie rod directs the steering action initiated in the steering gearbox, finally transmitting action of steering arm to the wheel. Short tie rot connects the joint to the gooseneck. It acts like a joint which transmits left or right action of selector lever backwards and forwards.

Has the same features of bogie arm. Uncontrolled movements of the vehicle wheels depending on the road conditions are transmitted to axle body. In commercial vehicles, V stay arm used for connecting the axes to the chassis enables a part of such uncontrolled movements and vibrations to be absorbed by the wheels, while large parts of them are transmitted to axle.

V Stay Arm differs from Stay Arm by being technologically more advanced and being connected to one joint.

Uncontrolled movements, which occurred on the wheels depending on the form of the road as a result of motion of the vehicle, are transmitted to axle body. In commercial vehicles, stay arm used for connecting the axes to the chassis dampens on the wheels a part of such uncontrolled movements and vibrations, while large parts of them are transmitted to axle.

Repair kits are located in the bodies of V stay arm and torque rod in order to minimize the forceful vibrations occurring due to road conditions.

ROTA produce steering system hydraulic cylinders for commercial vehicles and tractors. Also ROTA added top-link hydraulic cylinders for tractors and mechanical motion cylinders for agricultural equipment to its production portfolio.

ROTA produces its hydraulic cylinder through a production process, where each step is standardized and validated. Products are validated after field tests which are carried out under the real-life conditions. Once produced, products undergo a tightness test and controlled for sizes before shipment.
