Hydraulic servo of friction engaging device of automatic speed changing gear

Abstract

Abstract PURPOSE:To simplify the constitution of a one-way clutch and reduce the size of an automatic speed changing gear by engaging a circular drum, in which a fixed member inside a case is to be subjected to reaction of one-way clutch, on the sleeve part of the clutch through spline grooves and mounting a hydraulic servo inside said drum. CONSTITUTION:In this automatic transmission gear, a circular drum 4 is engaged through spline grooves on the sleeve part 2b of the inner race 2a of a one-way clutch F2 as to have the fixed member 3a inside the automatic transmission gear case 3 subjected to the reaction of the one-way clutch F2. A hydraulic servo which consists of both a piston 4P and a return spring 4a is mounted inside said drum 4. The end bearing of the one-way clutch may therefore be made compact so that the size of the automatic transmission gear can be reduced.
