Abstract

The invention proposes a vehicle hydraulic torque converter pump wheel optimal design method. Firstly, the parametric design is performed for a pump wheel; then, the arrangement simplification, the DOE analysis and the CCD analysis are performed for parameters of the pump wheel; and finally, results obtained by CCD are optimized. The vehicle hydraulic torque converter pump wheel optimal design method not only can shorten the research and development period of a hydraulic torque converter, but also is higher in precision, largely reduces the product research and development and production costs, and achieves important significance on hydraulic performance of the vehicle hydraulic torque converter.

Description

technical field [0001] An optimal design method for a pump wheel of an automobile hydraulic torque converter. technical field [0002] The invention relates to a method for optimizing the performance of an automobile hydraulic torque converter, in particular to a method for optimizing the design of a pump wheel of an automobile hydraulic torque converter. Background technique [0003] The hydraulic torque converter is a device used to transmit power between the engine and the transmission in the hydromechanical automatic transmission and some continuously variable transmissions. Vehicles equipped with hydraulic torque converters have the advantages of strong adaptability, high low-speed driving performance and good stability, and improve the comfort of the car and the service life of the vehicle. But compared with the mechanical transmission, the hydraulic torque converter has the disadvantage of low transmission efficiency, so it is necessary to optimize the performance ...
