Abstract

PURPOSE:To bond both a strip-shaped metal material and a lining material to each other with uniform surface pressure by providing a hole on the lining material larger than a projection in diameter at a position corresponding to a projection formed on the bonding surface of the strip-shaped metal material. CONSTITUTION:A bracket 14 is fitted to both ends of a strip-shaped steel material 10 with a rivet 12, thereby enabling braking operation. According to the constitution, the head 12a of the rivet 12 is formed as a projection on the bonding surface of a lining material 16 at the opposite side of the strip shaped metal material 10 where the bracket 14 is fitted. At a position corresponding to the projection 12a of the lining material 16, a hole 16a larger than the projection 12a in diameter is formed and the thickness of the lining material 16 is made larger than the height of the projection 12a. When the lining material 16 is pressed and bonded to the strip-shaped metal material 10, therefore, the pressing force is uniformly distributed all over without any hindrance by the projection 12a and lining density becomes uniform, thereby preventing the occurrence of separation and the like.

(b) Conventional technology As an example of a brake band used in a band brake device, brackets are attached to both ends of a flexible metal band using, for example, rivets, and the brackets are attached to the metal band on the opposite side. Some have lining material pasted on the sides.

When such a bracket is attached to a band-shaped metal material using a rivet as described above, one end of the rivet protrudes toward the surface of the lining. Since the lining material is attached to the entire surface of the band-shaped metal material, the lining material is also attached to the convex portion so as to cover it.

(c) Problems to be Solved by the Invention However, in the conventional brake band as described above, the lining material is pasted on the convex part that protrudes from the band-shaped metal material, so the lining material on the convex part is Since it is thin, the load concentrates on this part, causing the problem that the lining material around the protrusion may peel off. In addition, the lining material above the convex portion is compressed more strongly than other parts, so it has a higher density and has a lower oil content than other parts, so there is a problem that it is easily burnt out. That is,
The lining material around the protrusion has the lowest durability. The present invention aims to solve such problems.

(d) Means for Solving the Problems The present invention solves the above problems by not providing a lining material at the position of the convex portion. That is, the brake band according to the present invention is a brake band that includes a band-shaped metal material and a lining material attached to one side of the band-shaped metal material, and the lining material of the band-shaped metal material is provided with a convex portion on the surface side. A hole larger than the size of the protrusion is provided at a position corresponding to the protrusion of the lining material, and the thickness of the lining material is greater than the protrusion height of the protrusion. It is characterized by its large size.

(E) A hole in the lining material is arranged on the convex portion protruding from the functional band-shaped metal material, and no lining material is provided. Therefore,
The surface pressure of the lining material does not increase around the convex portion, and a uniform blood pressure state is achieved over the entire surface of the lining material. Furthermore, the density of the lining material becomes uniform over the entire surface. This prevents the lining material from peeling off, burning, etc., and improves durability.

(F) Embodiment Figures 1 and 2 show an embodiment of the present invention. This brake band is composed of a band-shaped metal material 10, a bracket 14 attached to the band-shaped metal material 10 with a rivet 12, and a lining material 16 attached to the side opposite to the side where the bracket 14 of the band-shaped metal material 10 is attached. The caulked portion of the rivet 12 becomes a convex portion t2a that protrudes toward the upper surface of the band-shaped metal material 10 in FIG. However, a hole 16a is provided in the lining material 16 at a position corresponding to the convex portion 12a, and no lining material is pasted on the convex portion 12a. Note that the thickness of the lining material 16 is greater than the protruding height of the convex portion 12a. The edge of the hole 16a is chamfered.

When the brake band is in use, it is wrapped around the drum and brought into a fastened state by the force of the hydraulic servo acting on the bracket 14. At this time, the blood pressure acting on the lining material 16 becomes uniform over the entire surface. This is because the hole 16a is provided at the position of the convex portion 12a, and the surface of the belt-shaped metal material 10 other than this is flat, so that the load is evenly borne. Furthermore, since the lining material 16 has a uniform thickness and a constant density, the oil content is also uniform, making it difficult for burns to occur. Also, hole 16
The edge of a is chamfered to prevent peeling from this area.
