Infinitely variable efficiency: New transmission, proven features
CLAAS has been using Eccom transmission technology for the continuously variable, power-split CMATIC drive in the XERION ZF since 2003. In addition to their high level of efficiency, the transmissons are characterized by enormous resilience, high reliability under all operating conditions and a long service life. Thanks to the low input speed, the XERION can work in numerous areas of application with a low rpm speed concept and therefore extremely economically. The modern Stage V Mercedes-Benz six-cylinder engines deliver high torque even at low engine speeds, so that the maximum torque of 2,200 (XERION 4200) to 2,600 Nm (XERION 5000) is readily available at 1,300 rpm. Most work can therefore be carried out in an efficient and quiet speed range of 1,150 to 1,300 rpm.
A major innovation in the XERION for model year 2023 is the change from the previous ZF Eccom 5.0 and Eccom 4.5 continuously variable transmissions to the new Eccom 5.5. Like the previous models, the new transmission offers four automatic range changes forward, with the mechanical drive area being further optimized. A maximum forward speed of 40 or 50 kph can be achieved at a fuel-saving 1,246 or 1,558 rpm. When reversing, a maximum of 30 kph is possible with three automatic driving ranges. The drives of the front and rear axles are rigidly coupled with each other, so that no longitudinal differential is required.
