Problems solved by technology

However, the electronically controlled clutch of the dual-clutch automatic transmission is complicated and unstable, which makes the car equipped with the dual-clutch automatic transmission prone to vibration when starting, and a sense of frustration when driving at low gear and low speed, which affects driving comfort.
At present, traditional hydraulic torque converters cannot be used in dual-clutch transmissions, and hydraulic torque converters have very strict requirements on axial space

Abstract

The invention discloses a hydraulic torque converter integrated with double radially nested type gear shifting clutches. The double gear shifting clutches arranged in the hydraulic torque converter are disposed in the hydraulic torque converter in a radially nested mode. The hydraulic torque converter has the advantages that the double gear shifting clutches are integrated in the hydraulic torque converter in the radially nested mode, so that the structure is simplified, the cost is lowered, and the axial structure of the hydraulic torque converter is more compact; starting is smoother, the comfort level is high, and the defect of obvious abrupt sense during low-gear low-speed forward moving is overcome.

Description

technical field [0001] The invention relates to a hydraulic torque converter, in particular to a hydraulic torque converter with integrated radially nested shifting dual clutches applied to a dual-clutch automatic transmission. Background technique [0002] The hydraulic torque converter is a device used in automatic transmissions to establish a flexible connection and transmission between the drive train and the engine, so that the car starts smoothly, accelerates uniformly, and softly. Due to its higher transmission efficiency, good fuel economy, and faster operating speed, dual-clutch automatic transmissions have been rapidly developed. However, the electronically controlled clutch of the dual-clutch automatic transmission is complicated and unstable, which makes the car equipped with the dual-clutch automatic transmission prone to shaking when starting, and a sense of frustration when driving in low gear and low speed, which affects driving comfort. At present, the trad...
