The KFBD series Constant Fluid Couplings are used on all industrial equipment driven by internal combustion engines up to 500 kW. By transmitting power through a fluid, they improve overall performance and protect both driving and driven machines.

THE BENEFITS OF CONSTANT FILL FLUID COUPLINGS

When you drive through KFBD Constant Fluid Couplings you profit from these Basic Benefits.

1 – Frees engine during heavy starts.
During heavy starts and sudden running load increases, engine lugging is prevented. The Fluid Coupling simply “slip” while it smoothly picks up the load.

2 – Provides smoothly drive
The mechanical connection is eliminated; power and torque are transmitted entirely through the fluid. The result is a smooth, sustained flow of energy minus the shocks and strains which, with mechanical drives, cut equipment life.

3 – Prevents transmission of shock loads
Fluid Couplings protect both driving and driven equipment by smoothing out shock loads and preventing them from striking solid resistance.

4 – Assures damping effects
Torsional vibrations from the engine are drastically dampened by Fluid Coupling, increasing the life of the entire driveline.

5 – Transmits full input torque
The patented Transfluid Circuit design delivers output torque always equal to the input torque. The engine can turn at its max torque-rpm, even when driven is at stall.

6 – High radial load capability
The KFBD hydraulic coupling series has also been designed for applications requiring pulley installation, particularly heavy-duty service.

TPO air clutches are powerful and reliable components, the technical development of which has been achieved with years of experience in transmissions.
Their performance range can fulfill the most different applications, with transmittable torques up to 1170 daNm, remaining constant without requiring any further regulation.
While having the great advantage of being modulated with air pressure variation, their compressed air feeding system can be remote controlled and automatically self compensate for wear.
The main technical features of TPO air clutches are:

• All the operating discs are made of high-quality cast iron, with large surfaces from where heat generated with friction is easily dissipated without creating dangerous tensile stresses.
• The friction discs are made of a composite compound without asbestos and are provided with external gear teeth to engage into the driving ring’s internal gears.
• The external dimensions are very small and for this reason the assembly phase is facilitated.
• The wide dimensions of the bores allow shafts with large diameters to be mounted.

In normal and medium operating conditions, clutches with 2 or 3 discs can be used, transmitting a torque twice or three times more than the corresponding one with a single disc, and leaving external dimensions unchanged.

TPH AIR CLUTCHES

The TPH air clutches model is designed for in-line drives and is based on the standard TPO clutch pack with a self-contained stationary thruster operating with 9 bar (130 Psi) air pressure.

TRANSFLUID has developed the HFO-HFR clutches to meet the growing market demand for power take-offs for high speed, high horsepower industrial engines, and remote-control operation.
HFO consists of an oil actuated clutch assembly (dry plates) with shaft and bearings suitable for high radial loads mounted in a cast iron housing that provides easy engine installation.

The connecting flange and housing to the engine are SAE standard. A rotating union provides the oil actuation mounted on the shaft end allowing the oil to engage and disengage the clutch.

This system allows the use of HFO clutches for belt-driven applications only. The oil actuation allows remote control as well as a larger transmittable torque compared to the traditional over-center PTOs. Due to the continuous pressure applied to the clutch plates, the HFO is a self-adjusting clutch that drastically reduces maintenance costs, especially on heavy-duty applications where plate wear is typical.
The HFR clutches have identical performances as HFO but it is designed for in-line applications. The oil actuation is provided by radial oil inlet in the bearing carrier allowing the same operation as HFO clutches.

CLUTCHES ACCESSORIES

MPCB

The MPCB controller is a dedicated printed circuit board entirely developed by TRANSFLUID, to monitor and control all functions of TRANSFLUID’s dry clutches, such as input and output speed, oil temperature and oil pressure. Our controller allows the soft engagement of the driven machine preventing nclutch overload and engine stalling;  therefore HF clutch and TowerClutch transmission are fully protected by unexpected failure due to misuse or abuse of the product.
The MPCB has been designed to continuously operate in heavy duty conditions; the most common applications are crushers, wood chippers, road milling machines, metal shredders, compressors and volumetric pumps.
The proprietary software is personalized according to the specific application and a separate Display can be integrated for a better view of all above mentioned parameters.
The MPCB  can be linked to the the engine control box via CAN BUS SAE J1939 protocol (or CAN BUS Open), consequently warning, alarm messages and any clutch status are transmitted via a single IP67 bus cable.
The MPCB enclosure is installed and wired on board the clutch through rubber mountings to dampen vibrations and shorten electric harnesses length.

With the exception of the MFO 110 power take-off, all remaining models are assembled with KEVLAR® DISCS for heavy-duty and torsionally active applications.
MFO mechanical power take-offs will allow:
– to simplify installation time (no pilot bearing alignment required)
– to increase uptime and engine life
– to reduce inventory

• with or without hub
• with spline or keyway
• with conical locking coupling
• with housing for hydrostatic drives

TECHNICAL CONSTRUCTION OF TRANSFLUID’S SHAFT COUPLINGS

The drive principle uses internal and external teeth; the only difference is that the external teeth are blocks of special rubber molded compounds.
The external ring, in aluminum, has a profile corresponding to the rubber molded compound and can be directly mounted on the output flange of the prime mover.
By this method it is also possible to absorb small angular and radial misalignments.

The spring-loaded SL brakes are designed for all applications where a fail-safe brake is required.
The brake consists of a hydraulic assembly, a plate assembly and a driven hub supplied by TRANSFLUID upon request or manufactured by the Customer.

SL BRAKES OPERATION

SL brake is a hydro-mechanical device that is Spring Loaded and hydraulically released.
A spring load exerts a compressive force between steel plates, which are mounted on the rotating shaft, and sintered plates mounted in the gear tooth ring.
When oil pressure is applied, the spring load is relieved and the plates are free to move axially on the shaft hub allowing free rotation of the shaft.
The brake is re-applied by releasing the oil pressure.
