Description

Technical Field

[0002] The torque converter is a device that converts a prime mover, such as an internal combustion engine, into a load that is driven by rotation. In vehicles equipped with an automatic transmission, the torque converter connects the power source to the load. It is usually located between the engine's flex plate and the gearbox. The main characteristic of the torque converter is that it can increase torque when the output speed is very low, thereby allowing the fluid flowing from the turbine curved blades to deflect from the stator when locked with the one-way clutch, thereby providing the equivalent of a reduction gear. This is a feature that goes beyond a simple fluid coupling, which can match the speed but does not increase the torque, thereby reducing power. Therefore, the power output interface of the torque converter is a very important structure, and how to withstand the large axial, radial loads and torque transmitted by the engine is very important. The power input interface of the existing torque converter is complex in structure and inconvenient to install, resulting in low production efficiency, poor structural stability, and unstable power transmission. Therefore, it is necessary to provide a torque converter power input interface device with a new connection structure to solve the problem of complex structure and inconvenient installation of the existing torque converter power input interface.
