METHOD AND APPARATUS FOR SUPPLYING COOLANT FOR MULTIPLE DISC CLUTCH AND MULTIPLE DISC BRAKE FOR AUTOMATIC TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To improve the efficiency of cooling a multiple disc clutch and a multiple disc brake for an automatic transmission.

SOLUTION: Within a range of a method for supplying a coolant to the multiple disc clutch and multiple disc brake for the automatic transmission of an automobile, the coolant flows through the multiple disc clutch or multiple disc brake 1 in a predefined manner toward the rotational center from the radially outer side or in a reverse direction, and at this time, a prescribed flow through the clutch or brake packet is ensured through the prescribed pressure difference of the coolant between an coolant inlet and a coolant outlet. The apparatus for supplying the coolant is formed as an annular passage 2 that partially or fully encloses the clutch or the brake 1.
