ZF PowerDivide, the engine-dependent PTO, is installed as a sandwich between vehicle engine and transmission.
With this modular system, ZF replaces and extends the proven engine-dependent PTOs which have so far only been available for the manual commercial vehicle transmissions Ecosplit and Ecomid. Its modular design allows ZF PowerDivide to also be combined with the TraXon, AS Tronic and AS Tronic mid automatic transmission systems.
Engine-dependent PTOs are particularly attractive for applications which require high torques for their auxiliary power units, such as concrete pumps, mobile cranes, airport crash tenders, or drilling and winch drives.
The new ZF PowerDivide is generously dimensioned with an output of 316 kW and a maximum torque of 2,000 Nm. It is available for different installation positions and with two different ratios. Moreover, it has a cooling circuit of its own. The integrated power-shiftable clutch combines the auxiliary system which is connected to the PowerDivide with the engine. This clutch is independent from the dry clutch that shifts between the PowerDivide and the transmission. For the first time it is also possible to combine the automatic and fuel-saving transmission systems of the TraXon and AS Tronic model ranges with a ZF PowerDivide. An SAE 1 interface allows the PTO to be connected to all common commercial vehicle diesel engines.
Many special vehicles depend on transmissions which can be combined with such an engine-dependent PTO, for example concrete pumps, sewer cleaning vehicles, airport crash tenders and mobile cranes. All of these applications require a rather high output for operating their pumps. With cranes, for example, there is a correlation between torque and setup times. With the new engine-dependent PTO, setup times can be reduced by half – a significant contribution to increased cost-effectiveness in operation.
Another advantage of ZF PowerDivide is the fact that it is designed for longer operating times. This is ensured by a separate oil and cooling circuit. A powerful torsional vibration damper is essential, since it balances the shocks caused by the irregular rotation of the crankshaft at the engine output.
