Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting member arranged on the innermost side of a vibration-proof rubber body such as a tubular engine mount or a vibration-proof bush of an automobile. More specifically, it relates to a mounting member having flat plate-shaped mounting portions at both ends in the axial direction.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, for example, a cylindrical bracket (not shown) of an automobile suspension arm.
The anti-vibration bush 50 press-fitted to has an elastic body 52 between the outer cylinder 53 and the mounting member 51 arranged in the innermost portion, and the mounting member 51 is fixed to the inner peripheral surface of the cylindrical elastic body 52. It is composed of a solid cylindrical central portion 51a and mounting portions 51b and 51c formed into a flat plate by cutting both ends of the central portion 51a. The mounting portions 51b and 51c respectively have mounting holes 54,
55, and bolts can be inserted into the mounting holes 54, 55 to be mounted on a vehicle body (not shown).

However, since the mounting member 51 is solid, it has a drawback that the weight is heavy and the cutting process requires a long time and is expensive.

In addition, in order to reduce the weight, it is known that the mounting member is formed by plastically deforming the both ends of a tubular member into a flat plate shape by forging, but the mounting member is located at the center. There is a problem that the hollow central portion is deformed during forging, and the accuracy of the mounting member is impaired.

A second joint end that is substantially joined in the circumferential direction and has a second bent portion adjacent to the first joint end at the other end in the circumferential direction of the second joint end. The plate piece includes a tubular portion that is a semi-cylindrical portion, and a flat plate portion that extends in the centripetal direction from the first bent portion and that is linearly connected to the second bent portion and that traverses the inside of the tubular portion. Has a wide portion in the central portion in the axial direction of the other, the width in the width direction of the other is wider than the width of both ends in the one width direction, the flat plate portion at the axial ends of the respective semi-cylindrical body portion. Axial direction It is obtained by constituting the mounting member, characterized in that is provided with a mounting portion formed in the protruding portions at both ends of the wide width portion which protrudes from both ends of the.

A third means is a mounting member made of a metal plate piece which is integrally fixedly disposed inside the rubber member of the vibration-proof rubber body to form the vibration-proof rubber body. A tubular portion having a pair of adjacent portions facing each other in the circumferential direction, and a joining end substantially joined to one adjacent portion of the tubular portion in the circumferential direction consisting of one end in the width direction of the plate piece. And a flat plate portion having a bent portion in the adjacent portion on the other side and extending the bent portion and traversing the inside of the tubular portion, the other end of the plate piece in the width direction on the other side. Has a wide width portion whose width in the width direction is wider than the width in the other width direction on the one end side, and the flat width portion protrudes at both axial ends from both axial ends of the tubular portion.

[0009]

The first means is, as described above, from a metal plate piece,
Since the mounting member can form a tubular portion, and the flat plate portion having the mounting portions projecting from both ends in the axial direction of the tubular portion at both ends in the axial direction is formed across the inside of the tubular portion, The weight can be reduced, and the structure can be configured accurately and inexpensively.

Since the second means is constructed as described above, the wide portion in which the width in the width direction of the other is wider than the width of both ends in the one axial direction is made of metal. A first half-cylindrical portion and a second semi-cylindrical portion to form a cylinder upper portion from a plate piece having a., And the other end of the first semi-cylindrical portion in the circumferential direction and the circumferential direction of the second semi-cylinder. The bent portions at the other end are linearly connected to each other to form a flat plate portion that traverses the inside of the cylinder upper portion, and a pair of mounting portions can be formed at both ends of the flat plate portion by the wide portions.

Since the third means is configured as described above, the width of the other width direction of one side of one width direction of the other side of one width direction of the other side made of metal is the same as that of the other width direction. From a plate piece having a wide portion wider than the width, a tubular portion is formed at one end side in the width direction, and the other end side having the wide portion is formed as a flat plate portion that traverses the inside of the tubular portion through a bent portion. Therefore, both end portions of the flat plate portion can be integrally formed with the attachment member as attachment portions.
