Title:
FOUR-WHEEL-DRIVE VEHICULAR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2018154206
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a four-wheel-drive vehicular control apparatus for suppressing noise generated in first and second meshing gear teeth and improving the durability of an elastic body.SOLUTION: In a case where variation of torque input from an engine 12 to a first clutch 24 is higher than a given value, causing noise to be likely generated between an inner spline tooth 54f of a ring gear 54 and an inner spline tooth 58a of a connect-disconnect sleeve 58, the connect-disconnect sleeve 58 is moved to a second meshing position to contact with an elastic body 62, and therefore the elastic body 62 suppresses force of the inner spline tooth 54f abutting the inner spline tooth 58a, thus reducing the noise generated between the inner spline tooth 54f and inner spline tooth 58a. Further, in the case of variation of the torque is equal to or less than the given value, with noise unlikely generated between the inner spline tooth 54f and inner spline tooth 58a, the connect-disconnect sleeve 58 is moved to the first meshing position so as to not contact with the elastic body 62, thus improving the durability of the elastic body 62.SELECTED DRAWING: Figure 3
