摘要:Variable-capacity matching of continuously variable-capacity double-impeller torque converter applied to a loader was studied in the article. Static variable-capacity matching of continuously variable-capacity double-impeller torque converter was performed under the two-impeller state and slipping state. Dynamic variable-capacity matching based on the V-shaped operating cycle was simulated in order to reflect the matching performance of the double-impeller torque converter more intuitively. The working speed of double-impeller torque converter together with engine was analyzed when the loader shoveled different materials, and the power performance and fuel economy of the whole machine were calculated. The continuously variable-capacity double-impeller torque converter applied to a loader could not only meet the requirements of matching different loader working conditions but also enhances the power performance and fuel economy of the whole machine in running condition compared with the original torque converter.
