The Role of One-way Clutch in Automatic Transmission
1. Introduction of one-way clutch
One-way clutch, commonly known as one-way bearing, is also a mechanical transmission basic part that can only be driven in a single direction (clockwise or counterclockwise). Its function is to make a component only rotate in a certain direction and lock in another direction. When the power source drives the passive element, it can only be driven in a single direction. If the power source changes direction, the passive element will automatically separate without generating any power transmission.
Since 1982, one-way clutches in automatic transmissions have become more and more popular, especially in middle and high-end models. The role of the one-way clutch is mainly to solve the problem of slipping caused by insufficient oil pressure due to the low oil pump speed when the vehicle starts, and to solve the problem of shift shock caused by the mismatch of speed. Although the hydraulic torque converter can play an important role in eliminating the shock of shifting, the one-way clutch is still the most effective way used to eliminate the shifting shock, especially in downshifting shock.
