ABSTRACT:
To prevent dust or muddy water from entering a hub housing or to prevent a hub clutch from being allowed to be inoperative, a hub clutch for selectively coupling or decoupling a wheel shaft to or from a clutch housing (to which a wheel is fixed), the hub clutch comprises a drive gear fixed to the wheel drive shaft; a slide gear axially slidably coupled to the clutch housing; a diaphragm fixed to the slide gear so as to partition an inner space of the clutch housing into an inner enclosed chamber and an outer enclosed chamber; and a control valve connected to an engine intake manifold vacuum, for selectively applying vacuum into the inner chamber and atmospheric pressure into the outer chamber or vice versa to move the diaphragm. Further, a piston plate and a spring can be used instead of the diaphragm.
