Hybrid and dual clutch transmission modules are now offered to the heavy truck sector as options with ZF’s TraXon modular platform. In addition to the conventional torque converter and dry clutch modules, this basic, compact transmission can be specified with TraXon Hybrid, integrating a 120 kW, 1000 Nm electric motor, and the TraXon Dual module, promised to deliver barely-perceptible gearshifts plus enhanced fuel economy and driver comfort.
The basic TraXon transmission can transmit torque of over 3000Nm, and can be ordered with 12 or 16 forward gears and two or four reverse gears; overdrive is an additional option. TraXon is said to emit 6 dB less noise than ZF’s previous AS Tronic system, thanks to its new design, improved housing and anti-rattling damper. ZF claims efficiency of 99.7%.
