Driving force transmission control apparatus
First Claim
1. A driving force transmission control apparatus comprising:
- an outer rotary member having an inner peripheral surface in which a plurality of inner peripheral spline teeth is formed, the inner peripheral spline teeth extending in a direction of a rotation axis;
an inner rotary member supported inside the outer rotary member so as to be coaxially rotatable relative to the outer rotary member, and having an outer peripheral surface in which a plurality of outer peripheral spline teeth is formed, the outer peripheral spline teeth extending in the direction of the rotation axis;
a multiple disc clutch including a plurality of outer clutch plates engaged with the inner peripheral spline teeth so as to be axially movable, and a plurality of inner clutch plates engaged with the outer peripheral spline teeth so as to be axially movable, the outer clutch plates and the inner clutch plates being alternately arranged in the direction of the rotation axis;
a pressing mechanism that presses the multiple disc clutch in the direction of the rotation axis; and
a control portion that controls the pressing mechanism, wherein the control portion makes a determination as to whether the multiple disc clutch is in a first operating condition in which the multiple disc clutch is pressed with a relative rotation speed between the outer rotary member and the inner rotary member being equal to or higher than a predetermined value, or in a second operating condition in which the multiple disc clutch is pressed with the relative rotation speed being lower than the predetermined value, and the control portion controls the pressing mechanism based on a result of the determination.

Abstract
A driving force transmission control apparatus includes a multiple disc clutch including a plurality of outer clutch plates, and a plurality of inner clutch plates; a pressing mechanism that presses the multiple disc clutch; and a control portion that controls the pressing mechanism. The outer clutch plates and inner clutch plates are engaged with an intermediate shaft and an inner shaft respectively. The control portion makes a determination as to whether the multiple disc clutch is in a first operating condition in which the multiple disc clutch is pressed with a relative rotation speed between the intermediate and the inner shafts being equal to or higher than a predetermined value, or in a second operating condition in which the multiple disc clutch is pressed with the relative rotation speed being lower than the predetermined value, and the control portion controls the pressing mechanism based on a result of the determination.
