On the outer circumferential surface 10b of the belt main body 10, which has a plurality of V-belt sections 11 formed on the inner circumferential surface 10a, magnetic members 20 are arranged in a row in the width direction at intervals in the longitudinal direction of the belt main body 10. Magnetic member 20
Embedded portions 21 are formed in the belt body 10, respectively, and the pulley F and idler G are formed on the outer circumferential surfaces of their respective side portions Fa and Ga.
Fb and Gb are configured so as not to come into contact with the inner circumferential surface 10c of the buried portion 21a of the buried portion 21 of each magnetic member 20 in the belt main body 10.

To further explain this structure, the pulley F

By providing this, a frictional force for driving the present magnetic belt E is obtained, so that the shape of each V-belt portion 11 can be reduced in size. As a result, not only can a large tractive force be secured, but also the bending rigidity of the magnetic belt E can be reduced, making it possible to reduce the diameter of the pulley F. Furthermore, the heat generation of the belt during driving can be reduced, making it durable. can significantly improve performance.

Further, as shown in FIG. 4 in this embodiment, the magnetic members 20 described above are arranged in rows in the width direction on the outer circumferential surface 10b of the belt body 10 at regular intervals in the longitudinal direction of the belt body 10. As shown,
A strip-shaped piece of iron with the required dimensions of length, width, and height is used, and a belt body 1 is placed on each side of the piece.
0 is formed.

To attach each magnetic member 20 to the belt body 10, as shown in FIG. 2, FIG. 3, and FIG. By arranging a side reinforcing layer 30b, which will be described later, on the upper surface side of the portion 21, that is, on the outer circumferential surface 10b side of the belt body 10, over the entire circumference of the belt body 10, both buried portions 21
is firmly held on the belt body 10, and the magnetic member 20 is firmly attached to the belt body 10.

Therefore, even when a large traction force and centrifugal force are applied to each magnetic member 20 when the vehicle is running, there is no fear that the magnetic member 20 will separate from the belt body 10.

In addition, as shown in FIG. 5, both the buried portions 21
They may be fastened to each other by a string-like locking member 40 made of a rubberized blind cord (about 4 cords).

As described above, the string-shaped locking member 40 works in conjunction with the side reinforcing layer 30b to prevent the magnetic member 20 from separating from the belt body 10 during operation of the magnetic belt E, and furthermore, This has the effect of firmly fixing each magnetic member 20 so that it can maintain a predetermined position during manufacturing of the present magnetic belt E, that is, during molding and vulcanization.

Further, as described above, since the magnetic members 20 are arranged in a row in the width direction at regular intervals in the longitudinal direction of the belt main body 10, the magnetic belt E is subjected to a bending action on the pulley during operation. At this time, the bending stress of the magnetic belt E can be minimized. As a result, the bending rigidity of the present magnetic belt E can be reduced, and the diameter of the pulley can be reduced.

The main reinforcing layer 31 mentioned above is formed to have a thickness of about 5 mm in this embodiment, and the reinforcing cords 31a are made of steel cords with a diameter of 2.8 mm and a tensile strength of 800 kg per piece. ing.

However, it goes without saying that a synthetic resin cord such as a polyester cord, nylon cord, or Kevlar cord may be used as the reinforcing cord 31a.

Further, the breaker layer 32 is formed to have a thickness of about 1 mm in this embodiment, and the reinforcing cord 32a
840D/2, 40 pieces/50mm nylon cord (polyester cord, textile cord, etc. may also be used) is used, and this reinforcing cord 3
The cord angle (crossing angle) of the reinforcing cord 2a with respect to the reinforcing cord 31a is set at 45 to 70 degrees.

This breaker layer 32 is a main reinforcing layer 31 constituting the reinforcing layer 30 when manufacturing the magnetic belt E.
The reinforcing cord 31a forming the main reinforcing layer 31 acts as a stabilizing layer to prevent the reinforcing cord 31a from being disturbed by external forces, etc., and furthermore, the reinforcing cord 3 constituting the main reinforcing layer 31 is
It has the effect of acting as a buffer band that prevents separation between 1a and the rubber compound 31b. Therefore, when used under low load and low stress, it is not necessarily necessary to use the breaker layer 32.

That is, (a) the pulley and the idler are constructed so that the outer circumferential surfaces of their respective opposite sides do not come into contact with the inner circumferential surface of the buried portion of the buried portion of each magnetic member in the belt body; When the magnetic belt is in operation, the vicinity of each buried part of the magnetic member is
The stress received from the pulley of the drive motor that drives the magnetic belt and the idler that guides the magnetic belt can be significantly alleviated, and the interference of the pulley and idler in the vicinity of each buried portion of the magnetic member can be reduced. As a result, the durability of the vicinity of each buried portion of the magnetic member can be greatly improved, and noise can also be reduced.

(b) Since the belt main body has a plurality of V-belt sections formed on its inner circumferential surface, it is not only possible to ensure a large traction force, but also to reduce the bending rigidity of the magnetic belt, making it possible to reduce the diameter of the pulley. Furthermore, the heat generation of the belt during driving can be reduced, and durability can be greatly improved.

(c) Since each magnetic member is arranged in a row in the width direction at regular intervals in the longitudinal direction of the belt body, when the magnetic belt is subjected to a bending action on the pulley during operation, the bending stress of the magnetic belt is can be minimized. Therefore, the bending rigidity of the magnetic belt can be reduced.
