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 bionic double-turbine hydraulic torque converter which comprises a pump wheel, a pump wheel outer ring, a pump wheel inner ring, a first turbine, a guide wheel and a second turbine. Blades of the guide wheel are bionic blades; a momentum distribution function polynomial of the blades is y=ax<3>+bx<2>+cx+d, the x is horizontal coordinates of equal division points on a mean camber line, and the y is a corresponding momentum distribution value; and the a is larger than or equal to 0.6044 and smaller than or equal to 1.4151, the b is larger than or equal to -0.5792 and smaller than or equal to -0.1698, the c is larger than or equal to -0.1989 and smaller than or equal to 0.581, and the d is larger than or equal to -0.4221 and smaller than or equal to 0.3746. Due to the fact that the blades of the guide wheel are bionic blades, the starting torque ratio and the efficiency of the bionic double-turbine hydraulic torque converter are improved compared with an original double-turbine hydraulic torque converter. Furthermore, the capacity coefficient of the pump wheel is larger than that of a hydraulic torque converter using general blades.

Description

technical field [0001] The invention relates to a twin-turbine hydraulic torque converter, in particular to a YJSW335 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 construct...
