Claas Industrietechnik (CIT) in Paderborn (Germany) recently produced the 10.000th unit of its EQ 2XX stepless transmission series. The EQ technology was introduced in 2015 and Claas has been using this successfully since then in its own Arion 500 CMATIC and Arion 600 CMATIC tractor series.
An automatic anti-jackknifing system has been available for these series since 2021, which is based on a precise coordination of engine speed, air brake and gear ratio and can be used for road transport with trailers as well as field use with square balers, vacuum tankers and manure spreaders, heavy trailed crop protection sprayers and fertilizer spreaders on slopes.
The mechanical-hydraulic power-split transmissions are characterized by two mechanical driving ranges and a consequently high, uniform overall efficiency over the whole speed range. The driving areas change automatically depending on the driving speed and the required load and allow to work in different driving modes. “The EQ 200 and the EQ 220, which was introduced in 2017, have proven their efficiency and fatigue strength in several thousand Arion tractors around the world over the past few years,” explains Dr. Ulf Leinhäuser, Managing Director of Claas Industrietechnik. “To date, thanks to the robust construction and manufacturing quality of our transmissions, some of these tractors have run up to 10,000 operating hours without any problems. The quality of each individual EQ transmission is assured by a computer-guided “zero-defect” assembly line and then additionally confirmed by a 100 percent test on a dynamometer. We are pleased that its performance is being honored by the growing interest shown by our customers. “
Claas Industrietechnik GmbH is part of the Claas Group and certified according to DIN ISO 9001-2015.
Strategic agreement with SDF Group
The cooperation of CIT and the SDF Group in Italy in the area of development, includes in particular the implementation of EQ 200, EQ 220 and EQ 260 continuously variable transmissions in the TTV drive train of higher horse power SDF tractors, as well as the joint coordination of the engine-transmission management.
