Title:
LUBRICATION DEVICE OF AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JP3669648
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To correct the either too much or too little of a lubrication amount at an upperstream side and lower streamside in the longitudinal direction of a rotary shaft, while ensuring durability, reliability or assembly workability sufficiently, in the lubrication device of an automatic transmission for supplying a lubrication oil supplied from a lubrication supply circuit to each lubrication required part arranged in the outer periphery side of the rotary shaft through an axial center oil passage in the rotary shaft.
SOLUTION: The flow rate of a lubrication oil discharged from a branch circuit 403 of the most upper streamside is made reasonable by installing a flow rate reasonable means 410 consisting of an auxiliary circuit 411, whose one end side is connected to a lubrication oil supply circuit 401, formed by crossing to the branch circuit 403 in the support members 13, 15 for supporting the outer periphery surface of a rotary shaft 120 rotarably, a spool installed slidably in this auxiliary circuit 411 and an elastic body by which this spool is energized to the one end side against the pressure P1 of the lubrication supply circuit 401 and which allows that the spool moves to the other end side for blocking the branch circuit 403 partially when the pressure P1 becomes more than a prescribed value.
