METHOD FOR CONTROLLING DIFFERENCE BETWEEN LEFT AND RIGHT ROTATION OF SIDE GEAR OF WORKING MACHINE

摘要

PURPOSE:To prevent only one wheel from rotation and stop by setting a necessary rotational difference between left and right wheels with a transmission to carry out a controlling action when energy acts which is going to exceed the set rotational difference. CONSTITUTION:The rotational frequency of a pinion gear shaft 3 is controlled by the rotational frequency of a working machine to control the rotational difference between left and right side gears 2. If the rotational frequency of the working machine is equalized to that of gear in the same row as the side gear 2 for converting 90 deg. the rotation of the pinion gear shaft 3, the rotation of the pinion gear 3 is controlled to zero without generating the rotational difference between the left and right side gears 2. Thus, by incorporating a transmission between the rotating working machine and the 90 deg. converting gear in the same row as the side gear can be obtained a necessary control valve of the rotational frequency of the pinion shaft 3.
