Komatsu has developed such a complex way hydraulic drive transmission, already used in the loaders, bulldozers and other construction machinery. Germany Fendt Vario tractors manufactured using type continuously variable transmission equipment, agricultural tractors Weinan Road mixing machine hydraulic repair prices in 2003 sold more than 30,000 units. "Wheel hydraulic drive means" the hydraulic motor is mounted directly in the wheels is an auxiliary hydraulic drive system, can solve the engineering machinery need to improve traction, but can not use all-wheel drive mode Weinan Road mixing machine hydraulic repair prices, difficult Layout Problem traditional mechanical transmission. Variable speed hydraulic transmission performance in different ways so that the drive wheels can coordination between synchronous Weinan Road mixing machine hydraulic service prices, which can also be seen as a power split transmission, in a sense: the power machine power is allocated to several groups of wheels, traction vehicle motion generating promote ground after coupling. Currently, many construction machinery manufacturers will use this technology for a partial self-propelled drive capability, such as the self-propelled graders and scrapers such machinery.
