Problems solved by technology

In the starting stage of the vehicle, the engine speed and torque are relatively low, which cannot meet the high torque demand of the vehicle in the starting stage
The cover assembly of the existing hydraulic torque converter is directly fixed to the flywheel plate of the flywheel assembly, and it adopts a hard connection method. This method is easy to make the engine and clutch be affected by vibration and reduce the service life
On the other hand, the torsional damper in the traditional hydraulic torque converter only plays the role of isolating the vibration of the engine. The torsional damping effect after locking is limited by the structure, so it cannot meet the requirements of low stiffness and large torsion angle.

Abstract

The invention provides an automobile dual-mass hydraulic torque converter which belongs to the technical field of machinery and solves the technical problem that the traditional hydraulic torque converter easily causes sympathetic vibration between an engine and a speed variator. The automobile dual-mass hydraulic torque converter is arranged between the engine and the speed variator and comprises a first-mass flywheel assembly and a second-mass hydraulic torque converter, wherein an elastic damping mechanism which can reduce the sympathetic vibration is arranged between the first-mass flywheel assembly and the second-mass hydraulic torque converter. The invention has the advantages of long service life and lower cost and can effectively reduce the sympathetic vibration between the engine and the speed variator.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a dual-mass hydraulic torque converter, in particular to an automobile dual-mass hydraulic torque converter. Background technique [0002] The existing dual-clutch power transmission route consists of engine → flywheel assembly → clutch 1 / clutch 2 → various transmission gears → final drive → differential → drive wheel. The size of the wheel driving force depends on the transmission ratio of each gear change gear and the size of the engine torque. In the starting stage of the vehicle, the engine speed and torque are relatively low, which cannot meet the high torque demand of the vehicle in the starting stage. The cover assembly of the existing hydraulic torque converter is directly fixed to the flywheel plate of the flywheel assembly, and it adopts a hard connection method. This method is easy to make the engine and clutch be affected by vibration and reduce the service life . ...
