DRIVING CONTROL SYSTEM FOR TRAVELING TRUCK

Japanese Patent JPS61229680

A

PURPOSE:To prevent driving wheels from racing, by making an auxiliary wheel at the front side of a running direction separable from a floor surface or the like all the time at the specified clearance, in case of a traveling truck which installs auxiliary wheels, for assisting a traveling attitude, in each leg jutting out in front and in the rear of the running direction. CONSTITUTION:Each driving wheels 3 is installed at both sides of a truck body 2, while each two of legs 4 are projected in front and in the rear of a running direction, and each auxiliary wheel 5 is installed in a tip end of each of these legs 4. Each leg 4 is rotated and moved in vertical directions by shifting devices 7a and 7b of a motor and the like. In a traveling truck 1 aforesaid, distance detectors 8a and 8b, which detect a distance of clearances with projections on a floor surface F or a projection on this floor surface F, are installed in a tip end of each of these legs 4, while a tilt detector 9 is installed in an upper position of the center of gravity O of the body 2. And, each output of these detectors 8a, 8b and 9 is inputted into a command operation processor 10, whereby these shifting devices 7a and 7b are controlled so as to cause the auxiliary wheel 5 at the front side to be floated with a minute clearance to the floor surface F.
