TRAVELLING DEVICE OF UNMANNED TRANSFER VEHICLE
Document Type and Number:
Japanese Patent JPH01223028
Kind Code:
A
Abstract:
PURPOSE:To simplify the construction and reduce the size and cost by connecting an operating disk turning integrally with rear wheels to a steering mechanism via a rod operating part having both transverse running and spin turn rods. CONSTITUTION:There is provided a steering mechanism 25 which steers both a connection gear 43 attached to a front wheel and an interlocker 50. On the other hand, a receival groove 53 which engages with the interlocker 50 is cut on an interlocking support board 51 axially mounted on a shaft pin 55. The interlocking board 57 and the change-over operation board 58 are overlapped on each other and axially mounted on a shaft pin 59 to turn together. A rod operating part which is able to selectively project a transverse running and spin turn rod 61 or 62 is mounted at the free end of the interlocking board 57. On the other hand, a receival groove 64 in which the rods 61 or 62 is inserted is cut in the middle position of the change-over operating board 58 corresponding to the rod operating part. The change-over operating board 58 is connected via a joint rod 65 to an operating disk 99 integrally turning with rear wheels.
