MECHANICAL SYSTEM

Planet gear

“N” position

• Driving force from input shaft is not transmitted to primary pulley because of idling caused by poor engage-

ment of forward clutch and reverse brake.

• Torque from wheel is not transmitted to input shaft because of idling of planetary carrier caused by poor

engagement of forward clutch and reverse brake.

• Since the Forward clutch is engaged, driving force from Input shaft rotates Sun gear in the positive direction

via Forward clutch.

• Therefore primary pulley rotates in the positive direction, and driving force is outputted in the forward direc-

tion.

Function

Torque converter

The torque converter is the device that increases the engine torque as well as the conventional CVT 
and transmits it to the transaxle.

Oil pump

This is a trochoid type oil pump directly driven by the engine. Discharged oil from oil pump is con-
veyed to control valve to be used for operating oil for primary and secondary pulleys, clutch, and for 
lubricant for each part.

Forward clutch

The forward clutch is wet and multiple plate type clutch that consists of clutch drum, piston, drive 
plate, and driven plate. It is a clutch to move the vehicle forward by activating piston hydraulically, 
engaging plates, and directly connecting sun gear and input shaft.

Reverse brake

The reverse brake is a wet and multiple plate type brake that consists of transaxle case, piston, drive 
plate, and driven plate. It is a brake to move the vehicle in reverse by activating piston hydraulically, 
engaging plates, and fixing internal gear.

Internal gear

The internal gear is directly connected to reverse brake drum. It is a gear that moves the outer edge 
of outer pinion gear of planetary carrier. It performs switching of forwards, reverse and others by fix-
ing or releasing internal gear.

Planetary carrier

The planetary carrier consists of carrier, inner pinion gear, outer pinion gear, and pinion shaft. It 
transmits traction force to move the vehicle in reverse when internal gear is fixed.

Sun gear

 Sun gear is a set part of planetary carrier and internal gear. It transmits transmitted traction force to 
primary fix pulley (FIX). It rotates in same or opposite direction according to activation of either for-
ward clutch or reverse brake.

Input shaft

The input shaft is directly connected to forward clutch drum and transmits traction force from torque 
converter. In shaft center, there are holes for hydraulic distribution to primary pulley and hydraulic 
distribution for lock-up ON/OFF.

Primary pulley

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the 
steel belt (the steel star wheels are placed continuously and the belt is guided with the multilayer 
steel rings on both sides). The groove width changes according to wrapping radius of steel belt and 
pulley from low status to overdrive status continuously with non-step. It is controlled with the oil pres-
sures of primary pulley and secondary pulley.

Secondary pulley

Steel belt

Manual shaft

The parking rod rotates the parking pole and the parking pole engages with the parking gear when 
the manual shaft is in “P” position. As a result the parking gear and the output axis are fixed.

Parking gear

Output gear

Reduction gear consists of primary deceleration (output gear and idler gear in pair) and secondary 
deceleration (reduction gear and final gear in pair). Each of them uses a helical gear.
