Abstract

The invention discloses a hydraulic driving component comprising a torque converter and a coupler. The hydraulic driving component comprises an input shaft, an intermediate shaft, an output shaft, the coupler and the torque converter, wherein the coupler and the torque converter are arranged at two ends of the intermediate shaft respectively. The coupler comprises a coupler pump wheel, a coupler worm gear, and a coupler back shell. One end of the input shaft is connected with the coupler pump wheel. One end of the intermediate shaft is provided with a shaft sleeve which is in interference fit with the intermediate shaft. The coupler back shell is connected with both the shaft sleeve and the coupler worm gear. The torque converter comprises a converter pump wheel, a converter worm gear and a guide wheel. The converter worm gear is connected with the intermediate shaft. The other end of the input shaft is connected with the converter pump wheel. The intermediate shaft and the output shaft are interconnected and coaxially located. The hydraulic driving component has the advantages that driving efficiency is improved, power loss is decreased and resources are saved.

Description

technical field [0001] The invention relates to a hydraulic transmission element including a torque converter and a coupling. Background technique [0002] The hydraulic transmission element is a blade-type transmission machine with liquid as the working medium. It mainly includes two types of hydraulic coupling and hydraulic torque converter. The hydraulic coupling is a non-rigid coupling with high transmission efficiency. Usually It can reach about 97%; the hydraulic torque converter is a torque amplifying device, its maximum output torque is about 6 to 7 times of the rated input torque, and the transmission efficiency can reach about 87% of the rated working condition. The hydraulic transmission has automatic Adaptability, stepless speed regulation, anti-vibration and vibration isolation, good starting performance, torque limit protection performance and other advantages, so it is widely used in transmission devices such as rail vehicles, construction machinery, lifting a...
