STRUCTURE AND OPERATION

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 pressures of primary pulley and secondary pulley.

Steel Belt

It is composed of multiple steel plates   and two steel rings 

stacked to a several number. The feature of this steel belt transmits

power with compression of the steel plate in contrast with transmis-

sion of power in pulling with a rubber belt. Friction force is required

with the pulley slope to transmit power from the steel plate. The force

is generated with the following mechanism:

Oil pressure applies to the secondary pulley to nip the plate. 

⇒The

plate is pushed and extended outward. 

⇒The steel ring shows with-

stands. 

⇒Pulling force is generated on the steel ring. ⇒The plate of

the primary pulley is nipped between the pulley. 

⇒Friction force is

generated between the steel belt and the pulley. 

Therefore, responsibilities are divided by the steel plate that trans-

mits the power with compression and the steel ring that maintains necessary friction force.   In this way, the

tension of the steel ring is distributed on the entire surface and stress variation is limited, resulting in good

durability. 

Pulley

The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope

(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-

sure chamber at the back of the movable sheave.

The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine load

(accelerator pedal opening), primary pulley speed and secondary pulley speed change the operation pres-

sures of the primary pulley and the secondary pulley, and controls the pulley groove width. 

FINAL DRIVE AND DIFFERENTIAL

The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and sec-

ondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.

STRUCTURE AND OPERATION

The lubrication oil is the same as the CVT fluid which lubricates the entire transaxle.

TRANSAXLE : Oil Pressure System 

INFOID:0000000011279266

Oil pressure required for operation of the transaxle transmission mechanism is generated by oil pump, oil

pressure control valve, solenoid valve, etc.

Part name

Function

Torque converter

Increases engine torque and transmits it to the transaxle.

Oil pump

Utilizes a vane-type oil pump that is driven by the engine through the oil pump drive chain in order to 
increase efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume 
in high-speed zone. Discharged oil from oil pump is transmitted to control valve. It is used as the oil of 
primary and secondary pulley operation, the oil of clutch operation, and the 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 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 planetary gear.

Internal gear

The internal gear is directly connected to forward clutch drum. It is a gear that moves the outer edge of 
pinion planet of planet carrier. It transmits power to move the vehicle in reverse when the planet carrier 
is fixed.

Planet carrier

Composed of a carrier, pinion planet, and pinion shaft. This gear fixes and releases the planet carrier in 
order to switch between forward and reverse driving.

Sun gear

Sun gear is a set part with planet carrier and internal gear. It transmits transmitted force to primary fixed 
sheave. It rotates in forward or reverse direction according to activation of either forward clutch or re-
verse brake.

Input shaft

The input shaft is directly connected to forward clutch drum and transmits traction force from torque con-
verter. In shaft center, there are holes for hydraulic distribution to primary pulley and hydraulic distribution 
for lockup 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 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 pressures of primary pulley and 
secondary pulley.

Secondary pulley

Steel belt

Manual shaft

When the manual shaft is in the P position, the parking rod that is linked to the manual shaft rotates the 
parking pole. When the parking pole rotates, it engages with the parking gear, fixing the parking gear. As 
a result, the secondary pulley that is integrated with the parking gear is fixed.

Parking rod

Parking pawl

Parking gear

Output gear

The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and 
secondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.

Idler gear

Reduction gear

Differential 

Torque converter regulator 
valve

Adjusts the feed pressure to the torque converter to the optimum pressure corresponding to the driving 
condition.

Pressure regulator valve

Adjusts the discharge pressure from the oil pump to the optimum pressure (line pressure) corresponding 
to the driving condition.

Torque converter clutch 
control valve

Adjusts the torque converter engage and disengage pressures.

Manual valve

Distributes the clutch operation pressure to each circuit according to the selector lever position.

Secondary reducing valve

Reduces line pressure and adjusts secondary pressure.

Primary reducing valve

Reduces line pressure and adjusts primary pressure.

Pilot valve A

• Primary pressure solenoid valve
• Secondary pressure solenoid valve
• Select solenoid valve
• Line pressure solenoid valve

Pilot valve B

Reduces pilot pressure and adjusts pilot pressure to the torque converter clutch solenoid valve.
