【産業上の利用分野】本発明は自動変速機の変速制御に
用いられる摩擦要素のドラムを軸部に支持するための構
造に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting a drum of a friction element used for a shift control of an automatic transmission on a shaft.

である。2. Description of the Related Art Automatic transmissions selectively operate (fasten) various friction elements (clutches, brakes, etc.) by operating pressure.
Thus, the power transmission path (gear stage) is determined, and the gear can be shifted to another gear stage by switching the friction element to be engaged.

これら内外筒部間に上記ピストンｄを摺動自在に嵌合
し、内筒部ｆを軸部ｇ上に回転自在に支持する。As shown in FIG. 3, for example, a friction element, particularly a clutch, includes a clutch drum a and a clutch hub b which are respectively rotationally connected to both rotating bodies to be driven and connected thereto, and which are rotationally engaged with these. In general, the clutch packs in which the clutch plates c are alternately arranged are pressed by a piston d that responds to the operating pressure so as to be in a fastened state in which the two rotating bodies are drive-coupled. The drum a has inner and outer cylindrical portions e and f,
The piston d is slidably fitted between the inner and outer cylinders, and the inner cylinder f is rotatably supported on the shaft g.

不合理である。On the other hand, when the drum inner cylinder f is rotatably supported on the shaft g, the drum inner cylinder f is directly connected to the shaft g.
When fitted on the upper part, the entire shaft portion needs to be made of a wear-resistant material, which is not preferable in terms of weight and is unreasonable in terms of cost.

う。Conventionally, as described in “Toyota A341E Automatic Transmission Repair Manual” (No. 63231), issued by Toyota Motor Corporation in November 1989, and as shown in FIG. A configuration has been proposed and put into practical use in which a sleeve h made of a wear material is fitted, and the drum inner cylindrical portion f is rotatably supported on the shaft portion g via the sleeve h. When the working pressure is supplied to the piston d fitted between the inner and outer drum parts e and f, this is performed via the operating pressure transfer part i between the inner drum part f and the sleeve h made of a wear-resistant material.

In the entire area including the delivery section area k, the structure is such that the shaft section g is press-fitted.

も抜本的な解決策とはなり得ない。In other words, according to the entire-area press-fitting of the sleeve h made of a wear-resistant material, the diameter of the sleeve is expanded also in the region of the operating pressure transfer section, and this causes the seal ring m to be inserted into the seal ring m before and after the operating pressure transfer section i. So-called hoop stress is generated, and its durability is impaired. The problem is that, at high temperatures, the hoop stress is originally applied to the seal ring m due to the difference in thermal expansion due to the difference in the material of the related parts.
It becomes even more noticeable. In order to solve this problem, it is conceivable to increase the wall thickness of the wear-resistant material sleeve h or to increase the press-fitting allowance for the shaft portion g in the operating pressure transfer area to increase the strength. Since the size of the sleeve h is increased, and the size of the drum support structure is increased, this is not a good solution. However, in the measures for increasing the strength of the wear-resistant material sleeve h by heat treatment, it is difficult to grind and finish the groove forming the working pressure transfer portion i to be performed thereafter. Cannot be a drastic solution.

It is an object of the present invention to solve the problem relating to the hoop stress of the seal ring without causing the above-mentioned problems.

するのを防止し得る。By the way, the bearing portion of the wear-resistant material sleeve that rotatably supports the drum inner cylinder portion and the working pressure transfer portion are separated in the axial direction, and the area of the wear-resistant material sleeve in the working pressure transfer portion is separated. Since the shaft inner periphery is fitted in a clearance fit type, the sleeve of the wear-resistant material does not expand in the operating pressure transfer region while reliably supporting the drum inner cylinder portion by the bearing portion, Hoop stress can be prevented from being generated in the seal ring before and after the operating pressure transfer section.

ともない。Therefore, in order to solve the problem relating to the hoop stress of the seal ring, the thickness of the wear-resistant material sleeve is increased in the operating pressure transfer region or the wear-resistant material sleeve with respect to the shaft portion as in the conventional structure. It is not necessary to increase the press-fitting allowance, and it is possible to avoid an increase in the size of the sleeve made of wear-resistant material, and hence an increase in the size of the drum support structure. Further, the sleeve made of the wear-resistant material does not need to be made to have a high strength by heat treatment, and the finish forming of the groove forming the working pressure transfer portion is easy, and the productivity does not decrease.
