Abstract
PURPOSE: To obtain a switchable steering device operable either by a left or a right steering wheel by a clutch pedal operation, by inserting and electromagnetic direction changeover valve between a pair of hydraulic power steering device and a hydraulic pressure source and by providing a pair of normally opened and normally closed contacts and a relay.
CONSTITUTION: Stepping-down a clutch 11a opens a normally closed switch 10a and closes a normally opened switch 12a, by a fluid pressure in a passage 22a. Then, closing a starter switch 17 actuates an electromagnetic coil 21a to connect a passage 4 to a passage 20. This makes a right steering wheel 9a operable, while a passage 7 of a left steering device 8 becomes idle as connected to a tank 1. On the contrary, stepping down a clutch 11 opens a normally closed switch 10 and closed a normally opened switch 12, by a fluid pressure in a passage 22. Then, the electromagetic coil 21a is not powered and an electromagnetic coil 21 is actuated. Thus, the left steering device 8 becomes operable while the right steering device becomes idle.
