Abstract

The invention relates to a double-turbine hydraulic torque converter. The double-turbine hydraulic torque converter aims to solve the problem that in an existing double-turbine hydraulic torque converter, a first-stage input gear shaft and a second-stage input gear shaft are of cantilever structures, so that the service life of bearings is affected, and the stability and reliability of gear transmission are affected. The double-turbine hydraulic torque converter is characterized in that a fifth bearing capable of bearing radial loads and axial loads at the same time is arranged between a second-stage input gear and a first-stage input gear, and the fifth bearing is located at the right end of the second-stage input gear. According to the double-turbine hydraulic torque converter, the first-stage input gear and the second-stage input gear are of double-point-supported simply supported beam structures, so that the stress on the first-stage input gear, the second-stage input gear, a firstbearing and a second bearing is improved, the service life of the bearings and the gears is prolonged, and the rotation stability and reliability are higher.

Description

technical field [0001] The present invention relates to a hydraulic torque converter, more specifically, to a twin-turbine hydraulic torque converter. Background technique [0002] The hydraulic torque converter is an important variable speed transmission part of the loader, among which the twin-turbine hydraulic torque converter is mostly installed on the 5-ton loader. [0003] Such as figure 1 As shown, the twin-turbine hydraulic torque converter consists of II-stage turbine 1, I-stage turbine 2, pump wheel 3, guide wheel 4, housing 5, input secondary gear 6, guide wheel seat 7, first bearing 8, input The primary gear 9, the second bearing 10, the casing 11, the thrust bearing 12, the overrunning clutch outer ring gear 13, the overrunning clutch intermediate shaft gear 14, the double bearing 15, and the cover wheel 16 form. [0004] The torque converter core is composed of a pump wheel 3, a stage I turbine 2, a stage II turbine 1, a guide wheel 4, a cover wheel 16, and d...
