The heart of the new development is a universal basic transmission in a very compact, robust design – featuring he top transmission efficiency of its class. The space-saving design and newly developed gearsets make TraXon a benchmark in power-to-weight ratio.
It can transmit torques of up to 2,800 newton meters. Thanks to various engineering features such as optimized housing geometry, ground gears and an integrated rattle damper in reverse gear, the noise level is one third below that of its predecessor model.
Modular in design, TraXon can be combined with additional systems. The wear-free ZF transmission brake intarder with a brake torque of up to 4,000 newton meters is integrated in the transmission housing and can be included in the vehicle's brake management system. Due to the common oil circuit, the intarder can cool the transmission oil or rapidly heat it to the optimal operating temperature.
The PreVision GPS predictive shifting strategy offers the option of linking the transmission to GPS data and digital maps. This avoids unnecessary shifting. As a result, the bus drives on average more economically and simultaneously faster.
Thanks to the clutch with integrated torsional vibration damper, fewer vibrations are transmitted from the engine to the transmission. The ConAct concentric clutch actuation system operates gently for reduced stresses on the driveline. Because ConAct contains fewer parts than conventional clutch actuation systems, it weighs less and also comes with less risk of failure.
