Problems solved by technology
[0003] The purpose of the present invention is to provide a twin-turbine hydraulic torque converter, which can solve the problem of the circulation circle of the twin-turbine hydraulic torque converter. Transition connection, the liquid flow direction changes sharply during the liquid circulation process, which increases the impact loss of the liquid flow and reduces the efficiency of the torque converter

The invention discloses a dual-turbine hydrodynamic torque converter, and relates to the technical field of machine manufacturing. The dual-turbine hydrodynamic torque converter comprises a pump wheel, a primary turbine, a secondary turbine and a guide wheel which are sequentially and coaxially arranged. The inlet and the outlet of a runner of the pump wheel, the inlet and the outlet of a runner of the primary turbine, the inlet and the outlet of a runner of the secondary turbine and the inlet and the outlet of a runner of the guide wheel are sequentially connected end to end to form a liquid flow circulating cavity. Streamline continuous transition linkage is achieved between a secondary turbine outlet of the liquid flow circulating cavity and a guide wheel inlet of the liquid flow circulating cavity and between a guide wheel outlet and a pump wheel inlet of the liquid flow circulating cavity. An inner ring of the guide wheel and an outer ring of the guide wheel are in a smooth-transition arc shape, the radius of the outer circle of the guide wheel is R, the radius r1 of the outer ring ranges from 0.7R to R, and the radius r2 of the inner ring ranges from 0.3R to 0.5R. By means of the dual-turbine hydrodynamic torque converter, the problem that liquid flow impact loss is caused when non-streamline linkage is achieved between a secondary turbine outlet and a guide wheel inlet of a liquid flow circulating cavity of an existing dual-turbine hydrodynamic torque converter and between a guide wheel outlet and a pump wheel inlet of the liquid flow circulating cavity of the existing dual-turbine hydrodynamic torque converter, and then efficiency of the existing dual-turbine hydrodynamic torque converter is reduced can be solved.
Description
technical field [0001] The present invention relates to the technical field of mechanical manufacturing, in particular to a twin-turbine hydraulic torque converter applied to construction machinery. The circulation circle of the twin-turbine hydraulic torque converter is a streamlined continuous transition between the outlet of the secondary turbine and the inlet of the guide wheel. The connection between the outlet of the guide wheel and the inlet of the pump wheel is a streamlined continuous transition; the inner ring and outer ring of the guide wheel of the twin-turbine hydraulic torque converter are circular arcs with a smooth transition. Background technique [0002] In the twin-turbine torque converter, the inlets and outlets of the flow passages of the pump wheel, the first-stage turbine, the second-stage turbine, and the guide wheel are connected end-to-end in sequence to form the circulation circle of the twin-turbine torque converter. The twin-turbine torque convert...
