Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art As shown in FIG. 6, as one type of a stator 1 used for a torque converter of an automatic transmission for a vehicle, a notch plate 3 is attached to an inner diameter side of a stator body 2 and is provided between the stator body 2 and the notch plate. Some support plates 4 are rotatably supported. Conventionally, the support plate 4 is entirely formed of resin.

However, if the support plate 4 is made of only resin as described above, the rigidity of the support plate 4 may be insufficient.

That is, in the support plate 4, a thrust load acting from the turbine side or the impeller side at the time of its operation is applied to the inner step portion 2 a of the stator main body 2.
Received at the end face 4b of the flange portion 4a, but the notch plate 3 must be rotatably supported.
Even when a load is applied to the sliding surface 4c of the support plate 4 due to the assembly structure, the load is applied to the end surface 4b of the flange portion 4a.
Will receive it. The sliding surface 4c is a portion that slides with a partner member (not shown). Therefore, as a result,
A load is applied to a portion 4d on the inner diameter side of the end face 4b of the flange portion 4a, and the bending moment of the inner diameter portion 4d increases.

[0005] When the amount of deflection of the inner diameter portion 4d of the support plate 4 increases in this manner, the inner diameter portion 4d becomes larger.
d interferes with the notch plate 3 to apply a thrust load to the notch plate 3, and when the stator body 2 idles with the notch side surface of the notch plate 3 subjected to the thrust load, the surface slides. In addition, there is a possibility that the resistance at the time of idling increases, or abnormal wear occurs in the thin plate 5 inserted into the stator 1 or the resin portion near the pocket portion 6 of the stator body 2.

On the other hand, when the amount of deflection of the support plate 4 is large, the actual contact surface of the support plate 4 that slides with the mating component only on the outer peripheral side is reduced, and the contact area is reduced. There is a possibility that the friction coefficient becomes large and the wear becomes large, so that the required sliding characteristics cannot be satisfied.
