Forward and Reverse Changeover System

ECVT Switching Mechanism:

FORWARD AND REVERSE SWITCHING MECHANISM
A synchromesh forward and reverse switching mechanism is installed between the electromagnetic powder clutch and primary pulley. This mechanism prevents gear squeaks while shifting from the "N" to the "R" position. It also permits gears to be shifted from the "N" to the "D" position, or vice versa, during operation.

ECVT "N" Position:

"N" position
This is the neutral state. The sleeve is at the center position and the main drive gear power is not transmitted to the hub.

ECVT "D" Position:

"D" position
This is the state in which the sleeve is shifted to the right at forward operation. In this state, the main drive gear power is transmitted from the sleeve to the primary pulley through the hub.

ECVT "R" Position:

"R" position
This is the state in which the sleeve is shifted to the left at reverse operation. In this state, the main drive gear power is transmitted from the counter gear to the primary pulley through the reverse idler gear. The direction of rotation is opposite that at forward operation.

OTHER SELECTOR POSITION MECHANISMS

"Ds" position
In this position, the sleeve position is the same as that of the "D" position. However, when the selector lever is set to the "Ds" position, the engine brake valve inside the hydraulic control valve operates and the shift characteristic changes to the "Ds" position speed change characteristic.

"P" position
In this position the parking rod is moved through the shift arm and selector cam, and the parking rod cam pushes the parking pawl in the arrow direction. Therefore, the parking pawl meshes with the parking gear at the side of the secondary pulley and the pulley, which is connected to the axle shaft, is mechanically locked. The sleeve remains meshed at the reverse side.
