Nissan Juke F15. Manual - part 1245

TM-170

< SYSTEM DESCRIPTION >

[CVT: RE0F10B]

STRUCTURE AND OPERATION

Planetary gear

“R” position

• Traction force from input shaft rotates sun gear in opposite direction of input shaft rotation because reverse

brake is engaged and planetary gear is fixed.

• Therefore primary pulley rotates in opposite direction of input shaft rotation and traction force output is in

opposite direction rotation.

“N” position

• Traction force from input shaft is not transmitted to primary pulley because forward clutch and reverse brake

are not engaged and run idle.

• Torque from wheel is not transmitted to input shaft because forward clutch and reverse brake are not

engaged and planetary carrier runs idle.

STRUCTURE AND OPERATION

Planetary gear

“D” position

• Traction force from input shaft rotates sun gear via forward clutch in the same direction of input shaft

because forward clutch is engaged.

• Therefore primary pulley rotates in the same direction of input shaft rotation and traction force output is in the

same direction rotation.

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 distribu-
tion for lockup ON/OFF.
