Automatic Transmission

Unique friction materials produce an excellent and smooth shift quality.

Lightweight, compact, and reliable shifting can be achieved.

The compact design for high torque capacity is established.

An optimal design to maximize functionality of the clutch.

A traction control system is achieved with high anti-shudder performance.

The action of roller and spring reduce drag torque remarkably.

Selection of the raceway washer and retainer type can be according to operating conditions, such as load, rotation speed, and lubrication.

A bearing and a raceway washer with anti-rotation function have been unified for easy assembly and high capacity.

For coping with increasingly high-speed rotations and low-friction torque while maintaining durability.

From sliding bearings to rolling bearings, low friction torque has been achieved by the technology of thin cross section drawn-cup bearings.

Smoother shifting is achieved by replacing sliding bearing with rolling bearing.

Special arrangement of balls achieves a reduction of rotational torque and sliding friction torque.

Reduced weight and costs have been achieved by using of PA46 plastic cage with superior oil and heat resistance. Initial internal clearance is used to provide optimum preload.

Original materials and heat treatment have been developed for longer life. Initial internal clearance is used to provide optimum preload.

The number of parts is reduced by unitization of the housing and outer ring, which also allows for easier assembly.

The outer ring has a mounting flange and splines, which attach to the one-way clutch. This affords greater compactness of FF-type automatic transmissions.

Reduced weight and costs have been achieved by using PA46 plastic cage with superior oil and heat resistance.

Maximum capacity in a limited space (thin section) has been achieved by high-level design technology, which promotes greater compactness of FF-type automatic transmissions.
