Hydraulic torque converter

Abstract

The invention discloses a hydraulic torque converter. The hydraulic torque converter comprises a box body, a movement assembly, an oil insulating plate, an output shaft, a turbine shaft and a power take-off shaft. The movement assembly, the oil insulating plate and the box body are sequentially assembled in the axial length direction of the turbine shaft, the box body is formed by a large box bodyand a biasing small box body cast integrally, the oil insulating plate is located between the movement assembly and the large box body, and the power take-off shaft and the output shaft are assembledon one side of the biasing small box body and located on the two sides of the turbine shaft correspondingly. A matching adaptation technology in which the same torque converter is compatible with different rated rotating speeds can be achieved, and the requirements for the whole machine traction power performance at different rotating speeds can be met.

Description

technical field [0001] The invention belongs to the field of large-tonnage torque converters, and in particular relates to a hydraulic torque converter. Background technique [0002] In the prior art, the large-tonnage hydraulic torque converter is one of the core components of large-scale construction machinery, and its comprehensive performance determines the life of the complete machine. The existing large-tonnage hydraulic torque converter cannot take into account the traction power performance of the complete machine at a certain speed between 1850 and 2050 rpm, and has defects such as high fuel consumption and low vehicle speed. The main reasons affecting its performance include the following points: 1. The connecting shaft of the cover wheel and the output shaft head are connected by bolts, and there is a possibility of loosening; 2. Oil leakage at the joint between the offset small box and the large box Problem; 3. The space between the offset small box and the larg...

The existing large-tonnage hydraulic torque converter cannot take into account the traction power performance of the complete machine at a certain speed between 1850-2050 rpm, and has defects such as high fuel consumption and low vehicle speed

The main reasons affecting its performance include the following points: 1. The connecting shaft of the cover wheel and the output shaft head are connected by bolts, and there is a possibility of loosening; 2. Oil leakage at the joint between the offset small box and the large box Problem; 3. The space between the offset small box and the large box and the middle section is limited, and there is no installation space for the free guide wheel. Moreover, the current product torque converter movement assembly and the large box have limited space and cannot be installed. Locking mechanism, it is difficult to upgrade and optimize the torque converter
