[CVT: RE0F10B]

COMPONENT PARTS

• When pressure is applied to the ceramic device in the secondary pressure sensor, the ceramic device is

deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Volt-

age is increased along with pressure increase.

CVT CONTROL SYSTEM : Line Pressure Solenoid Valve

INFOID:0000000012200859

• The line pressure solenoid valve is installed to control valve.

• The line pressure solenoid valve controls the pressure regulator valve. For information about the pressure

regulator valve, refer to

TM-173, "MECHANICAL SYSTEM : Component Description"

• The line pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].

NOTE:

• The principle of the linear solenoid valve utilizes the fact that the force pressing on the valve spool installed

inside the coil increases nearly in proportion to the current. This allows it to produce a fluid pressure that is

proportional to this pressing force.

• The N/H (normal high) produces hydraulic control when the coil is not energized.

CVT CONTROL SYSTEM : Secondary Pressure Solenoid Valve

INFOID:0000000012200860

• The secondary pressure solenoid valve is installed to control valve.

• The secondary pressure solenoid valve controls the secondary valve. For information about the secondary

valve, refer to

TM-173, "MECHANICAL SYSTEM : Component Description"

• The secondary pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].

NOTE:

• The principle of the linear solenoid valve utilizes the fact that the force pressing on the valve spool installed

inside the coil increases nearly in proportion to the current. This allows it to produce a fluid pressure that is

proportional to this pressing force.

• The N/H (normal high) produces hydraulic control when the coil is not energized.

CVT CONTROL SYSTEM : Torque Converter Clutch Solenoid Valve

INFOID:0000000012200861

• The torque converter clutch solenoid valve is installed to control valve.

• The torque converter clutch solenoid valve controls the torque converter clutch control valve. For information

about the torque converter clutch control valve, refer to

TM-173, "MECHANICAL SYSTEM : Component

Description"

• The torque converter clutch solenoid valve utilizes a linear solenoid valve [N/L (normal low) type].

NOTE:

• The principle of the linear solenoid valve utilizes the fact that the force pressing on the valve spool installed

inside the coil increases nearly in proportion to the current. This allows it to produce a fluid pressure that is

proportional to this pressing force.

• The N/L (normal low) type does not produce hydraulic control when the coil is not energized.

CVT CONTROL SYSTEM : Lock-up Select Solenoid Valve

INFOID:0000000012200862

• The lock-up select solenoid valve is installed to control valve.

• The lock-up select solenoid valve controls the select switch valve. For information about the select switch

valve, refer to

TM-173, "MECHANICAL SYSTEM : Component Description"

NOTE:

• The only operations of the valve spool installed inside the coil are pressing or not pressing the ball which

seals the hydraulic supply section into the seat. This A/T uses N/L (normal low) type.

• When voltage is not applied to the coil, the force of the pilot pressure presses the ball against the seat,

stopping the pilot pressure at that point.

• When voltage is applied to the coil, the valve is pulled in the direction of the coil, disengaging the hydraulic

seal which the ball creates. This supplies pilot pressure to the operating locations.

CVT CONTROL SYSTEM : Step Motor

INFOID:0000000012200863

The step motor changes the step with turning 4 coils ON/OFF according to the signal from TCM. As a result,

the flow of line pressure to primary pulley is changed and pulley ratio is controlled.

CVT CONTROL SYSTEM : Manual Mode Switch

INFOID:0000000012200864

• The manual mode switch [mode select switch and position select switch (shift-up/shift-down)] is installed in

the CVT shift selector assembly.

• The mode select switch detects the position (the main shift gate side or manual shift gate side) of the selec-

tor lever and transmits a manual mode signal or a not manual mode signal to the combination meter. Then,

the TCM receives a manual mode signal or non-manual mode signal from the combination meter.

• The position select switch (shift-up) detects that the selector lever is shifted to the shift-up side of the manual

shift gate and transmits a manual mode shift up signal to the combination meter. Then, the TCM receives a

manual mode shift up signal from the combination meter.

• The position select switch (shift-down) detects that the selector lever is shifted to the shift-down side of the

manual shift gate and transmits a manual mode shift down signal to the combination meter. Then, the TCM

receives a manual mode shift down signal from the combination meter.

CVT CONTROL SYSTEM : CVT Indicator

INFOID:0000000012200865

• CVT indicator is positioned on the combination meter.

• CVT indicator turns on for a certain period of time when the ignition switch turns ON, and then turns OFF.

CVT CONTROL SYSTEM : Shift Position Indicator

INFOID:0000000012200866

TCM transmits shift position signal to combination meter via CAN communication. The actual shift position is

displayed on combination meter according to the signal.

CVT CONTROL SYSTEM : Manual Mode Indicator

INFOID:0000000012200867

• Manual mode indicator (A) is positioned on the combination meter.

• The manual mode indicator illuminates when the selector lever is

operated to the manual shift gate side. It also displays the gear

position (M1

⇔

M8) when the selector lever is operated to the +

side or – side. (Operates only during driving.)

TRANSAXLE : Main Component Elements

INFOID:0000000012200872

TORQUE CONVERTER (WITH LOCK-UP FUNCTION)

In the same way as a conventional A/T, the torque converter is a system that increases the engine torque and

transmits the torque to the transaxle. A symmetrical 3-element, 1-stage, 2-phase type is used here.

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 second-

ary pulley operation, the oil of clutch operation, and the lubricant for each part.

FORWARD/REVERSE SELECTION UNIT

• A planetary gear type of forward/reverse selector mechanism is installed between the torque converter and

primary pulley.

• The power from the torque converter is input via the input shaft, operating a wet multi-plate clutch by means

of hydraulic pressure to switch between forward and reverse driving.

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.

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

STRUCTURE AND OPERATION

TRANSAXLE : Belt & Pulley

INFOID:0000000012200873

STRUCTURE

MECHANISM

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt

(the steel plates 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 pressures of primary pulley and secondary pulley.

STEEL BELT

It is composed of multiple steel plates (A) and two steel rings (B)

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.
