ABSTRACT:
A hub clutch assembly mounted between an axle and a hub of a four-wheel drive vehicle and having a 2WD/4WD position indicator that is simple in structure. A slide ring is axially slidably mounted on the axle. The slide ring is biased by a spring to a position in which an external gear formed on the slide ring engages an internal gear of an outer ring to maintain 4WD position. A magnet fixed to a cover attracts the slide ring to a 2WD position and keeps it in the 2WD position. The drive mode is changed between the 2WD mode and the 4WD mode by supplying pressure fluid only for a limited time period set by timers. A pressure gauge is provided in a passage for pressure fluid to indicate whether the current drive mode is the 2WD mode or the 4WD mode.
