Problems solved by technology

The working environment of bulldozers is generally harsh, and its electronically controlled traveling system is prone to various faults. In the existing technology, there is no effective detection method for the faults of the electronically controlled traveling system. There is no predictability for the occurrence of faults, and it is impossible to make preparations in advance , leading to abnormal damage to hydraulic components, clutch friction plates and other hardware, reducing the life of the whole machine

Abstract

The invention relates to a health detection method of a walking system, the walking system and a bulldozer. The health detection method of the walking system comprises the steps that after an engine is started, a controller controls electromagnetic valves of all gears to be powered on for a first preset time, then the pressure of clutches corresponding to the electromagnetic valves of all gears is detected, and whether the clutches corresponding to all gears have clutches with abnormal pressure or not is judged; if yes, it is displayed that the pressure of a certain gear is abnormal on a display; and if not, it is displayed that the system pressure is normal on the display. According to the invention, pressure self-inspection can be carried out on the clutches of all gears after the engine is started, so that abnormity can be found in advance, a driver can timely process the clutches of corresponding gears according to the prompt information of pressure abnormity of a certain gear displayed on the display, the pressure of the clutches of all gears is ensured to be in a normal state during operation, all-gear clutch friction plates are effectively protected, and the service life of the whole machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of bulldozers, in particular to a health detection method of a walking system, a walking system and a bulldozer. Background technique [0002] A bulldozer is an earthwork machine capable of excavating, transporting, and discharging rock and soil. The working environment of bulldozers is generally harsh, and its electronically controlled traveling system is prone to various faults. In the existing technology, there is no effective detection method for the faults of the electronically controlled traveling system. There is no predictability for the occurrence of faults, and it is impossible to make preparations in advance , leading to abnormal damage to hydraulic components, clutch friction plates and other hardware, reducing the life of the whole machine. Contents of the invention [0003] The purpose of the present invention is to provide a health detection method of the walking system, the walking system ...
