A torque converter consists of the hydrodynamic clutch device and the lock-up clutch device. The lock-up clutch connects directly between an engine and an automatic transmission for the high efficiency and the low fuel consumption. Recently, lock-up clutch is changed slip control instead of on-off control. The slip control of lock-up clutch is necessary for the better fuel economy. But slip control of lock-up clutch system has high thermal resistance and durability problem. The lock-up capacity and cooling flux are very important for solution of high temperature and durability. This test evaluates noise characteristics by the cooling hole of the slip controlled torque converter.

This test evaluates noise characteristics of a torque converter for different types of drive plates. The torque converter consists of the hydrodynamic clutch device and the lock-up clutch device. This prat is connected directly between an engine and an automatic transmission for the high efficiency and the low fuel consumption. Engine and torque converter are combined by a flexible drive plate, and engine power is passed to an automatic transmission. By applying different types of drive plates of torque converter, we can be found a change of the noise characteristics. As a result, the torque converter with the drive plate optimization is good for noise reduction.
