Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, the motor grader variable power control system includes a gearbox gear selection unit 1, an electronic control module 2, a transmission power selection unit 5, an engine ECU 6, and a manual / automatic switch 9. The engine ECU 6 can recognize the position signal of the electronic throttle sensor, and according to the sensor The signal controls the cycle fuel injection quantity of the electronically controlled engine 8, and the power selection unit 5 can realize the operation of the engine in different power modes by controlling the engine ECU6 through the power selection unit 5 and the manual and automatic switching switch 9. In the automatic control mode, the electronic control module 2 can receive and identify the shifting Gear position selection signal, the gear position information is transmitted to the engine ECU 6, and the engine ECU 6 ...

Abstract

The invention discloses a land lever variable-power control system, which belongs to the field of engineering machinery, and overcomes the weakness of the lever power control system in the prior art that the power loss is high due to the control of one power curve. The technical scheme is as follows: the land lever variable-power control system comprises an engine ECU (electronic control unit), a power selecting unit, a transmission gear selecting unit, an electronic control module and a manual-automatic switching switch, wherein the engine ECU can recognize a position signal of an electronic accelerator sensor, the engine ECU is controlled through the power selecting unit and the manual-automatic switching switch, so that the engine can work under different power modes, the electronic control module can receive a signal for recognizing the gear selection of a transmission, and the gear information is transmitted to the engine ECU. By adopting the land lever variable-power control system, a lever can output different power requirements which adapt to the different working condition, so that the energy is saved, and the labor intensity can be greatly alleviated.

Description

technical field [0001] The invention relates to a construction machinery control system, in particular to a variable power control system for a grader. Background technique [0002] Motor graders are typical traction-type operating machines. The working device is driven by the traction force of the machine. When the load is heavy, a large output torque is pursued, and a high driving speed is required when the load is small. The speed adjustment range of the grader is usually 0-40km / h, and the speed range for operation is usually 3-10km / h. At present, most of the domestic motor graders are hydraulic mechanical motor graders and the engine is a mechanical motor, which can only realize one power curve control. The engine power curve is designed for the maximum required power, but when working at low speeds, the traction force provided by the motor grader according to the maximum power is much greater than the maximum traction force determined by the ground adhesion conditions,...
