Abstract

Disclosed is a power transmission unit. The power transmission unit comprises a pump impeller and a turbine, wherein the pump impeller and the turbine are correspondingly arranged, the stage of the turbine is set to be more than two stages, and a fluid loop is formed by the pump impeller and the turbine to transmit the power. The power transmission unit is simple in structure, wide in variable torque range and high in efficiency.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a power transmission unit. Background technique [0002] Hydraulic transmission devices, such as hydraulic torque converters, are widely used, but the torque range is narrow and the efficiency is low. Therefore, it is necessary to invent a new hydraulic transmission device. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] A power transmission unit includes a pump wheel and a turbine, the pump wheel and the turbine are arranged correspondingly, the turbine is set in more than two stages, and the pump wheel and the turbine form a fluid circuit to transmit power. [0005] A power transmission unit includes a pump wheel and a turbine, the pump wheel and the turbine are connected in series, the turbines are arranged in more than two stages, and the pump wheel and the turbin...
