Two new powershift transmsision series were launched recently. The WG 100 tranmsmits 50-80 KW (85-110 hp), the WG 250 about 150-250 KW (200-370 hp) depending on the type of application. Helical gearing with high contact ratios results in a low noise level. High oil flow was provided to achieve good cooling, lubrication and shift quality. New methods of electric and/or automatic control modes are described. Options such as a retarder, integrated inter-axle differential, and an additional crawler gear were developed. An intense test program was necessary to achieve the high reliability goal.
