One-Way Clutch
One-Way ClutchLow one-way clutch
Structure
^ The low one-way clutch locks the clockwise rotation (seen from the side cover side) of the front planetary carrier. The low one-way clutch operates in D range of the 1GR.
^ The low one-way clutch inner race is integrated with the front planetary carrier, and the low one-way clutch outer race is fixed to the transaxle case.
Operation
^ The low one-way clutch inner race (front planetary carrier) rotates counterclockwise (seen from the side cover side) freely, but the rollers move to the shallower grooves and enter between the races to the rotation when the inner race tries to rotate clockwise.
^ The low one-way clutch locks the clockwise rotation of the front planetary carrier, and also locks the clockwise revolution of the rear planetary carrier via the low clutch.
Note: All direction of rotation are viewed from the side cover.
Reduction one-way clutch
Structure
^ The reduction one-way clutch counterclockwise rotation (seen from the side cover side) of the reduction sun gear.
^ The reduction one-way clutch outer race is integrated with the reduction sun gear, and the reduction one-way clutch inner race is fixed to the transaxle case.
Operation
^ The reduction one-way clutch outer race (reduction sun gear) rotates clockwise (seen from the side cover) freely, but the sprags rise to lock the rotation when the outer race tries to rotate counterclockwise.
^ The reduction one-way clutch locks the counterclockwise rotation of the reduction sun gear
Note: All direction of rotation are viewed from the side cover.
