Abstract

The invention relates to a hydraulic torque converter for a low-speed diesel engine, a cover wheel (1), a first turbine (2), a second turbine (3), a pump wheel (4) and a guide wheel (5) form a liquid flow circulation circle, the diameter of the liquid flow circulation circle is 338-342mm, and the height is 147-153mm; the blade inlet angle of the first turbine (2) is 101-110 degrees, and the blade outlet angle is 145-155 degrees; the blade inlet angle of the second turbine (3) is 30-42 degrees, and the blade outlet angle is 140-152 degrees; the blade inlet angle of the pump wheel (4) is 100-110 degrees, and the blade outlet angle is 94-106 degrees; and the blade inlet angle of the guide wheel (5) is 80-87 degrees, and the blade outlet angle is 19.5-25 degrees. The hydraulic torque converter can overcome the technical problem that the existing hydraulic torque converter can not be reasonably matched with the low-speed diesel engine, meet the need of being matched with the low-speed diesel engine, realize the reasonable structure, improve the output torque and the like.

Description

technical field [0001] The invention relates to a hydraulic torque converter, in particular to a hydraulic torque converter for a low-speed diesel engine. Background technique [0002] In order to meet the fierce market competition, the loader needs to reduce fuel consumption to save costs, which requires reducing the speed of the diesel engine used by the loader to reduce fuel consumption. However, the reduction in the speed of the diesel engine will cause the existing hydraulic torque converter to be unable to match it reasonably, which in turn will cause the power performance of the loader to decrease. While improving the fuel economy of the loader vehicle, it is ensured that the power performance of the loader vehicle is not reduced. Contents of the invention [0003] The object of the present invention is to provide a hydraulic torque converter for a low-speed diesel engine to overcome the technical problem that the existing hydraulic torque converter cannot be reaso...
