The C-330 tractor is one of the most widely used agricultural machines in Poland. Although it is a sturdy and reliable model, many farmers are opting for a modification, which is the installation of a power steering system. This system helps turn the wheels more precisely and easily, which is especially useful in difficult working conditions.
What is an orbitrol?
An orbitrol is a hydraulic control valve that is a key component of the power steering system in agricultural machinery. It works by transferring hydraulic fluid that affects the actuator to facilitate turning. The orbitrol translates the rotary motion of the steering wheel into a corresponding force in the steering system, resulting in easier maneuvering, even on difficult terrain or under heavy loads.
Types of orbitrols in power steering systems
- Orbitrol type ON
- Operating principle: In this system, the pump supplying the orbitrol pumps oil through a valve, and the power steering is activated only when the steering wheel is moved.
- Features: The ON-type orbitrol does not transfer response from the vehicle’s steering to the steering wheel. It is an unresponsive system, which means no perceptible forces on the steering wheel.
- Advantages: Precise operation thanks to an additional pressure regulating valve that maintains the correct level.
- orbitrol type OR
- Operating principle: Similar to the ON orbitrol, a pump pumps oil into the system. The difference is that the hydraulic power steering transmits the reactions from the wheels to the steering wheel, resulting in noticeable forces when turning.
- Features: The OR-type orbitrol has no additional pressure control valves, since the transfer of response from the steering to the steering wheel eliminates the need for such valves.
- Advantages: Better steering response feel, more dynamic system operation.
- orbitrol type CN
- Operating principle: In this case, the flow of oil through the valve occurs only when a movement of the steering wheel is made. In the neutral (straight ahead) position, no oil flow occurs.
- Features: The orbitrol maintains oil flow to precisely hold the steering components in position.
- Advantages: Allows precise steering without unnecessary oil flow, improving system efficiency.
- orbitrol type LS
- Operating principle: LS-type hydraulic orbitrols adjust the pump output according to the current needs of the system, based on the signal from the receivers.
- Features: It has an additional signal port to adjust pump operation according to demand.
- Advantages: Optimization of pump operation, better control over pressure and performance, energy savings.
Examples of orbitrol models for C-330
The choice of an orbitrol for the URSUS C-330 tractor depends on the type of use. Here are examples of popular models:
- Orbitrol 80 cm³/rev. – Designed for light use. Provides minimal power assistance, suitable for simple agricultural work on smaller areas.
- Orbitrol 100 cm³/rev. – The most commonly selected model for the C-330. It offers adequate booster power for medium-duty use, providing comfort for typical agricultural work.
- Orbitrol 125 cm³/rev. – For more demanding tasks, such as transporting larger loads. Increased power assist, but can be too sensitive in precise maneuvers.
- Orbitrol 160 cm³/rev. – A model dedicated to intensive use, such as in more difficult off-road conditions. It offers a lot of power, but may be too powerful for everyday agricultural work.
What kind of orbitrol to choose for URSUS C-330?
For the URSUS C-330 tractor, the most common solution for the power steering system is the ON orbitrol. Its reliability and simple design make it perfect for this type of hydraulic system, ensuring precise operation on smaller agricultural machines such as the URSUS C-330.
The optimum choice is the orbitrol 100, which perfectly matches the requirements of this tractor, offering adequate power and performance. Smaller orbitrols, such as the 80, may be too weak, while the 125 orbitrol will be too sensitive, which may affect comfort and steering precision. An orbitrol 160, on the other hand, is too powerful, making the system overly sensitive and not precise enough.
Choosing an orbitrol 100 provides the optimal balance between power and precision, making it the best option for the URSUSA C-330.
Summary
Choosing the right orbitrol for a C-330 tractor is crucial to ensure comfortable and efficient operation. This will make the power steering system significantly easier to maneuver the tractor, even under heavy loads or difficult conditions. Remember to pay attention to the compatibility of the orbitrol with the tractor’s hydraulic system and to adjust the capacity of the orbitrol to the type of work to be performed.
