  • Patent number: 5056634
    Abstract: A control apparatus of a remote type free wheel hub clutch includes an inner sleeve integrally rotatable with a wheel axle, a clutch ring integrally rotatable with the free wheel hub clutch, an actuating arrangement for changing the two-wheel and four-wheel driving operations by engaging or disengaging the clutch ring with the inner sleeve in response to a transfer shift position. The transfer shift position actuates a discriminating circuit for changing over from two-wheel driving operation to four-wheel driving operation or vice verse.

  • Patent number: 4991680
    Abstract: A control device of a remote free wheel hub mechanism includes a free wheel hub mechanism, an actuator and a control circuit. The control circuit further includes a two-wheel-drive circuit, a four-wheel-drive circuit, a transfer shift position detecting sensor, and an engine rotation drive detecting sensor. One of the two-wheel-drive circuit and the four-wheel-drive circuit in the transfer shift position detecting sensor moves to a closed condition independently of the shift position when the engine is stopped, and the transfer shift position detecting sensor correspondingly produces a signal of one of the two-wheel-drive and four-wheel-drive conditions, respectively. The engine rotation drive detecting sensor detects a rotational condition of an engine and produces a signal which closes one of the two-wheel-drive and the four-wheel-drive circuits when the engine is stopped.

  • Patent number: 4776441
    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.
