する際の摩耗を抑制するようにしている。In this type of V-belt type automatic transmission, a weight interposed between a movable pulley and a cam plate constantly moves in the radial direction in response to fluctuations in rotational speed to perform gear changes.
Weight wear becomes a problem. For this reason, as disclosed in JP-A-61-180057, a thin film layer made of a resin composite mixed with a solid lubricant is provided on the outer circumferential surface of the weight, so that the weight can be moved. This is to suppress the wear and tear.

に鑑みなされたもので、ウェイトの偏摩耗が低減できる
Ｖベルト式自動変速機を提供するものである。However, such a structure has a problem in that uneven wear of the weights cannot necessarily be reduced. This is because the weight is lubricated by a thin film layer provided on the weight, and the lubrication conditions for the weight's movable pulley are equal to the lubrication conditions for the cam plate, so the frictional force acting on the weight's contact area with them is approximately equal. Similarly, it is thought that this is because the weight moves in the radial direction without changing its posture, and the movable pulley and cam plate are always in contact with the same part of the outer peripheral surface of the weight. The present invention was made in view of the above circumstances, and it is an object of the present invention to provide a V-belt type automatic transmission that can reduce uneven wear of weights.

のである。In the V-belt automatic transmission according to the present invention, only either the cam surface of the movable pulley or the cam surface of the cam plate that the weight comes into contact with has a coefficient of friction smaller than that of the other cam surface in terms of sliding friction with the weight. A thin film layer is provided.

。In the present invention, the magnitude of the frictional force acting on the portion of the weight that contacts the movable pulley is different from the magnitude of the frictional force acting on the portion that contacts the cam plate, so that when the weight moves in the radial direction, It will start to rotate.

ことができる。Therefore, the coefficient of friction between the weight 11 and the solid film lubricant 14 is smaller than the coefficient of friction between the weight 11 and the cam surface 12, which acts on the portion of the weight 11 that contacts the movable pulley 3b. The frictional force acting on the portion of the weight 11 that contacts the cam plate 6 is smaller than the frictional force acting on the portion of the weight 11 that contacts the cam plate 6. As a result, the side of the weight 11 that contacts the cam plate 6 can be slid, and the side that contacts the movable pulley 3b can be rolled, and the weight 11 can be rotated when moving in the radial direction. That is, weight 1
The entire outer peripheral surface of 1 is covered with movable pulley 3b and cam plate 6.
It is possible to suppress uneven wear in which the outer peripheral surface is locally worn.

ので、より摩擦力を小さくしやすい構造となっている。Further, in the embodiment, since the solid film lubricant 14 is provided on the cam plate 6, the solid film lubricant 1
Processing steps such as coating No. 4 can be facilitated. This is because the cam plate 6 is not only smaller in shape and lighter in weight than the movable pulley 3b, but also has fewer restrictions than the movable pulley 3b, which requires smooth wall surfaces of the heddle. Moreover, the cam surface 13 of the cam plate 6
Since the angle of inclination is smaller than that of the cam surface 12 of the movable pulley 3b, the structure is such that it is easier to reduce the frictional force.

工程などを容易に行うことができる。The content of the present invention is that by providing a thin film layer only on either the cam surface 12 or the cam surface 13, the coefficient of friction of the weight 11 with respect to each cam surface is made different. Therefore, in addition to the solid film lubricant 14 described above, the thin film layer includes:
For example, a hard plating layer of di-Nokel phosphorus alloy obtained by Kanigen plating (registered trademark: Kanigen J), which is a type of chemical plating, can be used. In this case too,
It is preferable to perform a plating treatment on the cam plate 6, and a pretreatment process can be easily performed.

Although an example has been described in which the cam surface 13 of the movable pulley 3b is provided, the present invention is not limited thereto, and may be provided on the cam surface 12 of the movable pulley 3b. Further, the thin film layer may be applied to the entire surface of the cam plate 6 on the cam surface side, and in this way, the work of providing the thin film layer is facilitated.

摩擦力の大きさとを異ならせることができる。As explained above, according to the present invention, a thin film is formed on either the cam surface of the movable pulley or the cam surface of the cam plate that the weight comes into contact with, which has a smaller friction coefficient than the other cam surface in terms of sliding friction with the weight. Since the layers are provided, the magnitude of the frictional force acting on the portion of the weight that contacts the movable pulley can be made different from the magnitude of the frictional force that acts on the portion that contacts the cam plate.

As a result, it is possible to prevent the shift characteristics from changing over a long period of time.
