AI Technical Summary

Technical Problem

The lack of a turbine speed measurement structure in the transmissions of existing excavator loaders leads to unreasonable engine power distribution and low overall machine operating efficiency.

Method used

A turbine speed measuring structure is added to the transmission to obtain the turbine speed in real time by monitoring the rotational speed of the pinion on the forward shaft, and to distribute power in combination with the overall vehicle speed.

Benefits of technology

It enables monitoring of the overall machine status, improves the rationality of engine power distribution, and thus enhances the overall machine operating efficiency.
