Description

TECHNICAL FIELD

[0001] The utility model relates to loader variable torque converter turbine shaft speed measuring structure technical field, concretely relates to 3 tons loader variable torque converter turbine shaft speed measuring structure. BACKGROUND

[0002] China introduced 3 tons loader technology from abroad in the 60s of last century and began to research and produce. 3 tons loader variable torque converter assembly because of its reliable quality, in the structure aspect does not change too much, has been used until now, but with the increasingly fierce competition of engineering machinery market, the optimization of product function will make the product more competitive. At present, the steering hydraulic system and the loading hydraulic system of 3 tons loader share the same variable pump, when loading, the whole machine is in parking state, at this time, the variable pump mainly uses hydraulic energy for loading system, when the whole machine walks, the variable pump mainly uses hydraulic energy for steering system. Therefore, if the hydraulic energy can be reasonably distributed, the working efficiency of the whole machine will be greatly improved, but the existing problem is that the turbine shaft of the existing 3 tons loader variable torque converter does not set speed measuring structure, and the dynamic information of the whole machine cannot be transmitted to the variable pump in real time to reasonably distribute hydraulic energy. SUMMARY
