Abstract
A direct-coupling/differential changeover apparatus is provided with a speed change gear function and includes an input member, two output members, a reaction member, a planetary gear set, and a engage/disengage changeover apparatus for effecting engagement/disengagement between elements of the planetary gear set and the members and between two of the elements of the planetary gear set. The engage/disengage changeover apparatus establishes a direct-coupled power train between all input and output members by engaging any one of the elements of the planetary gear set with the reaction member and by engaging one of the two other elements of the planetary gear set with the input member and the remaining element of the gear set with two output members. A differential power train is established between the input member and the two output members and a differential relationship between the two output members by engaging any one of the elements of the planetary gear set with the input member and by engaging the other two elements with the two output members, independently of each other. Transfer between direct-coupling/differential modes in four wheel drive is attained, optionally with two wheel drive modes or with the neutral mode. The direct-coupling mode may have a different speed change ratio from the differential mode.
