Applying Our Core Technologies Focused on Size and Weight Reduction, and Hydraulic and Electronic Control Technologies
The driving force generated at the engine is transmitted to four tires with this mechanism.
The driving force must be distributed to four tires according to the terrain and traveling state to realize low fuel consumption and stable travel.
JTEKT applies multiple core technologies while centering on the bearing technologies and hydraulic/electronic control technologies, so that we have products boasting the top share.
The drive line maintains the vehicle speed and transmits the driving force even when the axle or tire is placed at an odd angle.
Engine rotation is transmitted to the differential.
Torsen LSD (Limited Slip Differential)
The driving force transmitted from the propeller shaft is redirected 90 degrees and distributed between left and right axles according to the terrain and traveling circumstances.
The torque distribution ratio used for the rear differential and so on of the rear-drive sports vehicles is high with this model.
The high-speed cornering and bad-terrain driving limit performance is improved to achieve generous high-dimensional drivability.
Immediate torque distribution suitable for the terrain not available with open differentials is possible.
While the advantage of the original response of Torsen is enjoyed, this multi-purpose model supports various applications with wide adaptability ranging from the front differential to the rear differential.
Through adoption of a planetary gear type, size reduction and weight reduction are aimed at and, with uneven torque distribution between the front and rear, high driving stability is brought to the vehicle with the center differential devoted to four-wheel-drive vehicles.

Installed in an FF vehicle, it distributes the driving force to the front and rear axles.
Intelligent torque controlled coupling(ITCC)
Difference in rotation between the front and rear axles is detected and electronic control makes it possible to distribute the torque optimally for the driving state and terrain between the front and rear axles.
Because the center differential mainly adopted in full-time four-wheel-drive vehicles becomes unnecessary, size reduction and weight reduction can be realized, contributing to improved fuel consumption.
