A Computer Controlled Transfer for Four-Wheel Drive Vehicles 850354

The purpose of this paper is to outline a new computer controlled transfer for four-wheel drive vehicles, which AISIN-WARNER LIMITED of Japan has developed in cooperation with TOYOTA MOTOR CORPORATION.
Certain difficulties still remain with shafting of a conventional transfer. Coupled with a 4-speed automatic transmission, the new transfer discussed in this paper consists of 3 wet clutches, a simple planetary gear set, a chain for front drive and a control unit. This transmission-transfer combination (30-80LE) has realized “ON THE GO SHIFT” for easier operations of the 4WD applications.
