1. A free wheel hub clutch device comprising:
- a cylindrical body having a first end connected to a wheel hub and a second end connected to a cover, said cylindrical body including an inner spline;
an inner sleeve installed in said cylindrical body and fitted to a drive shaft extending through an axle tube, said inner sleeve including an outer spline;
a slidable clutch member having an outer spline fitted to said inner spline of said cylindrical body and an inner spline selectively connectable to said outer spline of said inner sleeve;
a handle including a cam surface and a handle sleeve which is rotatably supported by said cover;
a cam follower having a first end formed with a pawl which slides on said cam surface and a second end which impinges upon said clutch member for causing the clutch member to slide, said cam follower being secured to said handle sleeve;
a first tension spring arranged between said handle and said cam follower to bias the handle and cam follower toward one another;
a second tension spring arranged between said cam follower and said clutch member to bias the cam follower and the clutch member toward one another;
a motor fixed to the device including driving means comprising a motor shaft and a gear for selectively rotating said handle; and
control means for controlling said motor.

Abstract
A free wheel hub clutch device includes a cylindrical body, an inner sleeve, a clutch member, a handle, a cam follower, a first tension spring, a second tension spring, a motor and a control. The control has an electrical charging apparatus and controls the motor which is attached to the free wheel hub clutch device. A sealing member is interposed between a wheel hub and an axle tube. With this construction, it is feasible to change from a two-wheel driving system to a four-wheel driving system and vice versa by manipulating a switch at the driver seat and further to prevent an outflow of grease from a bearing.
