Embodiment Construction

[0051] Such as figure 1 As shown, the YJSW335 twin-turbine hydraulic torque converter includes a pump wheel 1 , a pump wheel outer ring 11 , a pump wheel inner ring 12 , a first turbine 2 , a guide wheel 3 , and a second turbine 4 .

[0052] The vane measurement parameters of each component in the twin-turbine hydraulic torque converter are as follows: figure 2 As shown, including the chord length, thickness, maximum camber, entrance angle, exit angle, etc. of the section.

[0053] 1. Bionic blade

[0054] 1.1 Second turbine bionic blade,

[0055] The present invention uses bionic technology to change its circulation distribution function on the basis of not changing other structural parameters of the second turbine blade, and the circulation distribution function polynomial is: y=ax 2 +bx+c. Among them, x is the abscissa of each equal point on the middle arc, and y is the corresponding distribution value of circulation. The value ranges of parameters a, b, c are as foll...

Abstract

The invention relates to a coupling bionic double-turbine hydraulic torque converter. The coupling bionic double-turbine hydraulic torque converter comprises a pump wheel, a pump wheel outer ring, a pump wheel inner ring, a first turbine, a guide wheel and a second turbine. Vanes of the pump wheel are bionic wheels. The polynomial of the circular rector distribution function of the pump wheel is y=ax4+bx3+cx2+dx+e, wherein x is the transverse coordinate of each equal diversion point on an arc line, y is the corresponding circular rector distribution value, 3.0619<=a<=6.0894, -6.0787<=b<=-3.8151, -0.406<=c<=0.0147, -0.1814<=d<=0.4725, and 0.5972<=e<=1.5149. The vanes of the pump wheel are bionic wheels. Compared with a traditional common double-turbine hydraulic torque converter, the starting torque ratio and efficiency are increased, and the capacity factor of the pump wheel is larger than that of a hydraulic torque converter with common vanes.

Description

technical field [0001] The invention relates to a twin-turbine hydraulic torque converter, in particular to a YJSW335 coupling bionic twin-turbine hydraulic torque converter. Background technique [0002] The hydraulic torque converter is a transmission device that uses liquid as the working medium and uses the change of kinetic energy to realize the conversion and transmission of torque and speed. It has the advantages of load self-adaptation, stepless speed change, vibration reduction and vibration isolation, and stable low-speed performance. At present, among all kinds of construction machinery, hydraulic transmission has occupied an absolute dominant position, and is widely used in construction machinery, automobiles, military industry and petroleum machinery, etc., and is a key component of vehicle transmission system. The efficiency of its operation has an important and direct impact on the economy and emissions of the vehicle. However, the efficiency of the existing ...
