Features
1、The YL254ET pure electric tractor is driven by a motor and uses a lithium iron phosphate battery as the power source. It is energy-saving and environmentally friendly. It is a new energy tractor. The launch of this model indicates that the Yellow Sea Golden Horse tractor has achieved initial results in the exploration of new energy applications.
2、YL254ET pure electric tractor adopts Dual-Motor working mode. It has significant advantages such as high peak power and strong obstacle crossing function, and can withstand short-term overload operations
3、YL254ET pure electric tractor, innovatively developed a special transmission system for electric tractors, the power motor is directly connected with the gearbox, and the transmission efficiency and installation accuracy are high. The main variable speed power motor has stepless speed regulation, and is equipped with a two-speed auxiliary transmission with a meshing sleeve or synchronizer shifting, which can meet the operating speed requirements of different machines.YL254ET纯
4、The power output system innovatively adopts an overrunning clutch, which can ensure that the power output shaft will not reverse when the motor is reversed. A standard 540/1000 Rpm Pto output is set, which can be applied to farmland operations and gardening operations.
5、Using CAN bus technology, key technologies such as central integrated control and overall machine control strategy, energy management in power mode and economic mode, stepless speed regulation, power matching under different working conditions of operating units, and overall machine integration are studied.
6、The control system adopts digital signals, and the tractor's forward and backward operation are operated by one key. Through further research on the automation, intelligence, and networking of smart electric tractors, it will gradually transition to the future unmanned operation of tractors and the grouping operation of multiple tractors.
7、YL254ET pure electric tractor has an overall flat floor, large space, and all control handles are placed on the side, with good operating comfort and excellent ergonomics of the whole machine
8、The launch of YL254ET pure electric tractor coincides with the formulation of national electric tractor industry standards. The acquisition of basic data such as PTO power test, traction power test, hydraulic lifting power test, field test, etc., provides a reference for determining the standard parameters of the electric tractor industry .
