Title:
DIFFERENTIAL TYPE MULTIPLE SPINDLE DRIVE MECHANISM
Document Type and Number:
Japanese Patent JP2016037268
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a system for controlling plural drive systems, in which at least one back-up drive motor is used by plural drive systems in common, for minimizing a number of drive motors.SOLUTION: Drive systems are respectively connected to a wheel 5 via a motor 1 and a differential gear 8, and are connected to a wheel 15 via a motor 16 and a differential gear 18. Between the differential gear 8 and the differential gear 18, a central side motor 9 is connected as a back-up motor. When any of the motors is broken, a normal motor maintains rotation of both wheels 5, 15 via the differential gears 8, 18.SELECTED DRAWING: Figure 5
