Title:
HYDRAULIC TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/065118
Kind Code:
A1
Abstract:
Hydraulic servo mechanisms 205, 208 for actuating hydraulic continuously variable transmissions 64, 70 are arranged within a continuously variable transmission case 323 so as to be separated to either side of the hydraulic continuously variable transmissions 64, 70. In an oil path block 401 are formed closed-loop oil paths 201, 202 for the hydraulic continuously variable transmissions 64, 70, and a charge oil path 219 connecting the closed-loop oil paths 201, 202. Servo oil paths 402, 403 connecting the charge oil path 219 and the hydraulic servo mechanisms 205, 208 are formed from the oil path block 401 toward the continuously variable transmission case 323 so as to cross the charge oil path 219 at a right angle and extend parallel to each other.
