AUTOMATIC TRANSAXLE SYSTEM


  1. CONSTRUCTION


    1. For the following reason, a centrifugal fluid pressure canceling mechanism is used on the C1 and C2 clutches.

    2. Gear shifting operations are affected not only by the valve body controlling fluid pressure but also by centrifugal fluid pressure from the fluid that is present in the clutch piston oil pressure chamber (chamber A). The centrifugal fluid pressure canceling mechanism uses chamber B to reduce the effects of the centrifugal fluid pressure due to the fluid in chamber A. As a result, smooth shifting with excellent response is achieved.

    3. Chamber B is filled by fluid supplied to the shaft for lubrication. As a result of filling chamber B, there is the same amount of fluid pressure due to centrifugal force on both sides of the piston. This cancels the effect of fluid pressure on the piston due to centrifugal force. Accordingly, it is not necessary to discharge the fluid through the use of a check ball, and highly responsive and smooth shifting characteristics are achieved.
