Description
Technical Field
The invention relates to a turbine structure of a hydraulic torque converter, in particular to a novel turbine structure of a hydraulic torque converter with a round wheel circle and a space three-dimensional streamline blade structure.
Background
The turbine of the hydraulic torque converter is driven by kinetic energy and pressure energy transmitted by the pump impeller to rotate, meanwhile, the turbine converts the transmitted liquid energy into mechanical energy in the rotating process, and the mechanical energy is transmitted to a transmission device such as a transmission connected at the back through an output shaft of the hydraulic torque converter. Part of working oil flowing out of the turbine enters a circulation system of the hydraulic torque converter to dissipate heat, and part of working oil passes through a fixed and non-rotating guide wheel to convert part of pressure energy into kinetic energy, and the kinetic energy returns to an inlet of the pump wheel after the rotation degree is increased. Working oil circularly flows in the circular space cavity of the hydraulic torque converter in this way, so that the normal operation of the hydraulic torque converter is formed.
The turbine of the hydraulic torque converter has larger three-dimensional distortion degree of the blade space due to larger angle difference between the inlet and the outlet, and has certain difficulty in design and manufacture. At present, in order to improve the torsion degree of turbine blades, the domestic hydraulic torque converters have different circular formulas and larger space three-dimensional blade structure differences. Circular, egg-shaped, half egg-shaped, rectangular and other types of circulations are available. In order to adapt to various circulations, the blades are designed into cylindrical blades similar to streamline, equal-thickness blades with smaller twisting degree and the like, and the blades with complete streamline are fewer. Under the same blade inlet and outlet angle, the hydraulic torque converter has larger difference in performance level due to the difference of the circulation circle and the space three-dimensional blade structure of the hydraulic torque converter, and particularly, the influence on the transmission efficiency is most obvious. In all structures, the hydraulic torque converter with the circular cycle and the approximate streamline blade structure has the advantages of best performance, stable whole working condition transition, wide high-efficiency range, best matching of the high-efficiency point speed ratio and the rated working condition of the engine, and improved processing and manufacturing difficulty. The other structures adopt cylindrical blades, so that the overall performance is reduced, the highest efficiency of the individual hydraulic torque converter is improved, but the high-efficiency point is moved backwards, the high-efficiency range is narrowed, the whole machine with performance requirements on the whole working condition is not suitable, and the machine with coupling working condition is suitable for the machine type with coupling working condition. The invention combines the actual use working condition of the hydraulic torque converter, considers the difficulty of the simulation manufacturing processing of the blade mould and the blade casting parting, develops a circular structure and a space three-dimensional streamline blade structure which are approximate to a circle, improves the integral transmission efficiency of the hydraulic torque converter obviously through repeated optimization design and test verification, and has stable trend of integral transmission performance from a braking working condition to a high-speed working condition, wide high-efficiency range and perfect matching of a high-efficiency point speed ratio and the rated working condition of the whole machine. The performance of the hydraulic torque converter should be at a leading level in China.
