Axial flow type guide vane adjustable hydraulic torque converter and guide vane adjusting method

The invention discloses an axial flow type guide vane adjustable hydraulic torque converter and a guide vane adjusting method. The axial flow type guide vane adjustable hydraulic torque converter comprises a pump impeller, a turbine, a guide wheel assembly and a casing, wherein an output shaft of the engine drives the driving wheel and the pump impeller to rotate, and further drives working liquid in the casing to flow, the mechanic energy of an input shaft is converted into kinetic energy of liquid, the working liquid enters the turbine and a guide wheel of the guide wheel assembly from the pump impeller, and flows back into the pump impeller to form liquid circulation, the working liquid drives the turbine and the output shaft to rotate, the kinetic energy of the liquid is converted into the mechanic energy of the output shaft, and a vane of the guide wheel assembly is connected with an adjusting mechanism, and is an adjustable vane. The axial flow type guide vane adjustable hydraulic torque converter has the advantages that by adjusting the opening degree of a guide vane, the capacity value of the hydraulic torque converter is changed, the property of the hydraulic torque converter is improved, and the dynamic matching between the engine and the hydraulic torque converter is realized; the operation productivity is improved, the dynamics and economy properties are improved, and the energy-saving and emission-reduction effects are realized.
