Title: POWER TRANSMISSION DEVICE AND CONSTRUCTION MACHINE
Abstract:
A first planetary gear set (126) includes a first sun gear (130) to which power is input from a hydraulic motor (124). The first planetary gear set (126) includes a first carrier (132) and a first ring gear (133). The first carrier (132) and the first ring gear (133) are able to rotate in conjunction with rotation of the first sun gear (130). A second planetary gear set (127) includes a second sun gear (135) configured so as to rotate integrally with the first carrier (132). A hydraulic clutch mechanism (128) allows or prohibits the rotation of the first ring gear (133).
