Title:
SUSPENSION MECHANISM FOR OMNIDIRECTIONAL MOVING WHEEL AND SELF-PROPELLED TRANSPORT BOGIE USING THE MECHANISM
Document Type and Number:
Japanese Patent JP2019209896
Kind Code:
A
Abstract:
To provide a self-propelled transport bogie using omnidirectional moving wheels having a suspension for enhancing a degree of freedom of the selection of a size of a constituent member such as a damper and a parallel link without imposing an excess load to a drive component such as a motor.SOLUTION: The transport bogie having omnidirectional moving wheels 21, motors 11 and parallel links 3 comprises: wheel-side blocks 2 for supporting the omnidirectional moving wheels 21; motor-side blocks 1 for supporting the motors 11; rotation connecting parts 5 arranged on side-face upper parts of the motor-side blocks 1; transmission rods 6 connected to side-face lower parts of the wheel-side blocks 2 at lower ends, connected to the rotation connecting parts 5 at upper ends so as to be rotatable, respectively, and arranged in diagonal directions of the parallel links 3; dampers 7 connected to side-face lower parts of the motor-side blocks 1 at lower ends, and connected to the rotation connecting parts 5 at upper ends so as to be rotatable, respectively; and transmission shafts 4 having universal joints for connecting drive shafts 12 of the motors 11 and wheel shafts 22 of the omnidirectional moving wheels 21.SELECTED DRAWING: Figure 1
