Abstract

PURPOSE:To increase the binding force of a V type metallic member onto a belt member, by installing a stopper member being opposed to a circumferential surface of the belt member in the V type metallic member, while pressing this stopper member to the top of the circumferential surface under pressure. CONSTITUTION:An elastic metallic member 9 is engaged with concave surfaces 10 and 10 made up between V type metallic members 8 and 8 and simultaneously fastened tight by a metallic member 7 from the circumference whereby mutual binding force between these members 7, 8 and 9 is made so as to be given. In addition, a stopper member 12 being opposed to a circumferential surface of the belt member 7 is installed in the V type metallic member 8, and with this stopper member 12 pressed forcibly to the circumferential surface, the V type metallic member 8 is bound onto the belt member 7, through which binding by the belt member 7 is made so as to be yet more reinforced.

Description

[Detailed description of the invention] The present invention relates to a metal belt type power transmission device.

The applicant of the present invention has previously developed this hammer device by sequentially placing a plurality of V-shaped metal members and a plurality of elastic metal members in contact with each other on a metal belt member made of an endless steel band or the like. A type in which the belts are arranged alternately to form a V-belt as a whole, and this belt is stretched between the driving side ■ pulley and the driven side ■ pulley to transmit power between both pulleys. In this step, each elastic metal member is formed into a hollow roller, which is engaged with each concave surface of the opposing surface of each pair of the square metal members on both sides, and is tightened from the outer periphery with the metal belt member. proposed a method in which each v-shaped metal member is bonded to the metal belt member via each elastic metal member, but in this case, the mutual bonding between each v-shaped metal member and the metal belt is There is a need to further increase the

The object of the present invention is to obtain a device that meets these requirements, and includes a plurality of V-shaped metal members and a plurality of elastic metal members in a metal belt member made of an endless copper band or other material. are arranged alternately in contact with each other to form a V-belt as a whole, and this is stretched between the V-pulley on the driving side and the V-pulley on the driven side to transmit power between both pulleys. Further, each elastic metal member is formed into a hollow roller and is engaged with each concave surface formed on the opposing surfaces of each pair of V-shaped metal members on both sides, and the belt member Each V-shaped metal member is fastened to the belt member by tightening from the outer periphery, and each V-shaped metal member is provided with a stopper member facing the outer circumferential surface of the belt member, The belt member is characterized in that the square metal member is fixed onto the belt member by pressing a stopper member onto the outer circumferential surface.

Embodiments of the present invention will be described with reference to attached drawings.

In the drawing, reference numeral 10 indicates a continuously variable transmission for a combined vehicle. (5) between the V-belt (
It consists of a type in which power is transmitted between both pulleys (2) (41) by tensioning the pulleys (6).

The V-belt (6) has a plurality of V-shaped metal members (8) and a plurality of elastic metal members (9) on a metal belt member (7) consisting of an endless plow board. In this case, each elastic metal member (9
) is composed of a hollow roller, which is engaged with each arcuate concave surface α0) (10)K formed on the opposing surface of each pair of said V-shaped metal members (8) t8) on both sides thereof. The metal belt member (7) is tightened from the outer circumference by a knife, and thus, according to the tightening, the belt member (7) is tightened by each elastic metal member (9).
), through which each V-shaped metal member (8) was pressed so that mutual bonding was provided between the members (7), (9), and (8). To put it simply, each V-shaped metal member (8) is positioned and fixed on the belt member (7), and thus, due to its engagement with the drive-side bushing (2), When the belt member (7) rotates, a tension-side driving force is applied to the belt member (7) accordingly.

Each V-shaped metal member (8) is made of a relatively thick plate-like block, and is provided with a substantially U-shaped groove αυ that opens outward, and is inserted into the belt member (7) at the groove aυ. I made it so that it would be done.

In this case, the height position of the belt member (7) is approximately at the center of the engagement surfaces with the pulleys on both sides of the V-shaped metal member (8).

Although the above is not particularly different from the previous KW proposal, according to the present invention, each V-shaped metal member (8) is provided with a stopper member α facing the outer peripheral surface of the belt member (7), and the stopper member α By pressing the member (121) against the outer peripheral surface, the ■-shaped metal member (8) is bound onto the belt member (7), and the binding by tightening the belt member (7) as described above is achieved. This strengthens each V.
The shaped metal member (8) is stably fixed on the belt member (7) by being fastened by tightening the belt member (7) and by being pressed by the stopper member. .

The stopper member 02) is inserted into and engaged with a pair of left and right retaining grooves 03) α3) at the upper part of the above-mentioned concave groove 0]), and has an arc-shaped surface at its tip. A convex surface α41 is provided so that the convex surface a4J is pressed against the outer circumferential direction of the belt member (7).

In the ones shown in FIGS. 1 to 5, each stopper member U is of a type that is always in pressure contact with the outer peripheral surface of the belt member (7), but this is not always in pressure contact as shown in FIGS. 6 and 7, for example. It is possible to make it a model. That is, in the one shown in FIGS. 6 and 7, the stopper member a2 is allowed to move up and down slightly within the left and right engaging grooves 03) (f3), and the belt member (While ensuring that the member (L2) is not pressed against the force, the tail end of the member (L2) extends rearward (
In 12a), the inner surface of the receiving seat member (8a) (8,a) extending forward from the top of the ■-shaped metal member (8) located behind it is exposed to the inner surface of the seat member (8a), and thus each V
When the shaped metal member (8) sequentially engages the pulley (2) and tilts, the stopper member 02 is brought into contact with the seat member (8a) (8a) at the tail end (12a). Pushed by this, it tilted downward in the drawing, so that the member was brought into contact with the convex surface (141) on the belt member (7).More specifically, the member ( 12+ tilts downward in the drawing with the tip point A as the axis to form the convex surface 0 (a)
The ■-shaped metal member (8) is pressed onto the belt member (7) at the upper point B, and the ■-shaped metal member (8) is pressed onto the belt member (7) by the pressure contact.
It was made to be in a state where it was tied to the top.

In this way, according to the present invention, each V
The shaped metal member is bound onto the belt member, and has the effect of increasing the binding compared to the conventional method using only the tightening.
