Porous flow guide type power blade for hydraulic torque converter

Abstract

The invention discloses a porous flow guide type power blade for a hydraulic torque converter, and relates to the technical field of power blades, in particular to the porous flow guide type power blade for the hydraulic torque converter, which comprises a shell, a driving disc is mounted on the inner side of the shell, and power blades are fixedly mounted on the surface of the driving disc. Mounting grooves are formed in the peripheries of the interiors of the power blades. According to the porous flow guide type power blade for the hydraulic torque converter, through the bending shape of the power blade, when the power blade makes contact with gearbox oil, the gearbox oil can be blocked through the bending position of the power blade, and the problem that the gearbox oil is prone to being separated from the power blade can be effectively solved; by means of the driving grooves formed in the power blades, the contact area between gearbox oil and the power blades can be increased, so that hydraulic loss can be effectively reduced, and the working efficiency of the power blades is improved.

[0002] The working principle of the hydraulic torque converter is: the hydraulic torque converter is composed of the pump wheel turbine and the guide wheel. There is transmission oil in the hydraulic torque converter. After starting the engine, the pump wheel will rotate, so that the transmission oil will From the guide wheel to the wheel, the guide wheel will also rotate under the action of the transmission oil. The pump wheel is connected to the flywheel of the engine, and the turbine is connected to the power input shaft of the gearbox. The guide wheel is sandwiched between the pump wheel and the turbine wheel, and the pump wheel and There is a special structural design on the turbine, so that the transmission oil can be used to transmit power. The hydraulic torque converter is composed of a pump wheel, a turbine, and a guide wheel. It is installed between the engine and the transmission, and the hydraulic oil ( ATF) is the working medium, which plays the role of torque transmission, torque conversion, speed change and clutch, while the impeller is the core of the hydraulic torque converter, its type, arrangement position and blade shape determine the performance of the torque converter Function, the traditional rectangular power blades have a short contact time with the transmission oil during use, and the contact area is small, resulting in a lot of hydraulic loss, and the faster the impeller rotates, the more hydraulic loss, and when the speed changes When the tank oil is driven by centrifugal force, the transmission oil will leave the power blades. At this time, the blades are not cooled by the transmission oil, and the temperature will rise rapidly, increasing the loss of the blades and reducing the service life of the blades. In view of this, here is a proposal A porous guide type power blade for hydraulic torque converter to solve the above problems
