Title:
DRIVE FORCE DISTRIBUTION DEVICE FOR AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2015/125390
Kind Code:
A1
Abstract:
In the drive force distribution device for automobiles, the inner wall surfaces of clutch oil chambers (26R, 26L) in the hydraulic clutches (21R, 21L) are provided with circular oil grooves (33R, 33L, 34R, 34L) that face the clutch pistons (25R, 25L). The positions of the hydraulic oil supply ports (35R, 35L) and the hydraulic oil discharge ports (36R, 36L) that communicate with the oil grooves (33R, 33L, 34R, 34L) differ in the left and right hydraulic clutches (21R, 21L). Because the cross-sections of the oil grooves (33R, 33L, 34R, 34L) are set to be larger for greater distances between the hydraulic oil supply port (35R, 35L) and the hydraulic oil discharge port (36R, 36L) at the two ends, the flow channel resistances in the oil grooves (33R, 33L, 34R, 34L) of the respective hydraulic clutches (21R, 21L) are equalized. As a result, it is possible to achieve smooth operation of the hydraulic clutches (21R, 21L), improve engagement responsiveness, and equalize engagement responsiveness.
