Coincidence and torque converter belong to "soft connection" organization, they have many advantages. But the cohesive device has obvious disadvantages, high speed, pump wheel and turbine, larger slip happens between transmission power dropped substantially, especially reflected in coincidence point, after a long time, the configuration of automatic transmission car fuel consumption high primary crux lies in this. So what is the effect of locking clutch?


When the car traveling resistance hour, the engine speed is higher, at the moment there is no need to increase the torque, lock the clutch will torque converter pump wheel and turbine lock, can improve the transmission power, can save about 5%.


In the car when the moving resistance is large, the engine speed decreases, now lock the clutch separation, to increase the torque.


Torque converter lock clutch's primary function is: in the car low speed, the use of torque converter low speed increase characteristics, improve the car start and bad road acceleration; At high speeds, the torque converter locks the clutch effect, enabling hydraulic coincidence (" soft connection ") to allow for direct mechanical transmission (" hard connection "), improving transmission power and reducing fuel consumption.


Torque converter locking has a clutch pressure plate, when applying pressure oil, engine and transmission has become rigid. Low speed, the torque demand, and hydraulic coincidence effect. However, when the speed reach cannot achieve increase torque converter (generally greater than the speed of 50 km/h), effect of locking clutch, hydraulic coincidence effect failure.
