Abstract

PURPOSE:To improve the yield of friction board by forming the friction board with a plurality of arched boards sticked in circumferential direction on the sideface of disc brake body. CONSTITUTION:A disc brake 9 is provided with a disc brake body 13 tightened through a screw to a disc wheel 6. An annular friction board 15 composed of a plurality of arched boards 18 is sticked in the circumferential direction on each sideface of the outercircumferential section of disc body 13. The adjoining joint 19 of said board is inclined radially. The arched boards 18 can be punched while bringing near each other thereby the yield is improved. While since the joint 19 is inclined, it can slide smoothly.

Description

ーキパッドとを有している。(Prior Art) A disc brake installed in a motorcycle or the like has a brake disc that rotates together with the wheel, and a brake pad that slides against the side surface of the brake disc and performs a braking action when the brake is operated.

却される。]-The brake disc may be constructed as follows in order to prevent high temperatures due to friction with the brake pad. That is, a brake disc main body is supported on the wheel side, and a large number of protrusions projecting approximately radially outward are formed on the outer circumference of the brake disc main body. An annular friction plate that can slide into contact with the brake pad is attached to each side of the outer circumference of the brake disc body. The space surrounded by the adjacent protruding pieces and the friction plates is an air circulation hole, and the centrifugal force caused by the rotation of the brake disk causes air to flow through the circulation hole to cool the brake disk.

ところで従来、上記摩擦板は環状に一体成形されている
ため、この摩擦板を成形する際の板取り面積は大きくな
るものであり、これは歩留りの点で好ましくない。Conventionally, the friction plate has been integrally molded into an annular shape, so the area of the cutout when molding the friction plate becomes large, which is unfavorable from the viewpoint of yield.

。Therefore, it is conceivable to improve the yield by constructing a friction plate by sequentially joining arc-shaped plates that require a small cutting area. However, with this configuration, even if there is a slight difference in the joint between adjacent arcuate plates, when this joint slides on the brake pant, the difference in height will cause abnormal noise and rattling. There is a possibility that this may occur.

The purpose is to prevent problems such as abnormalities occurring during brake operation.

It is formed of arc-shaped plates, and the joining portions of these adjacent arc-shaped plates are formed to be inclined with respect to the radial direction.

伺けられている。To explain the brake disc 9 shown in I-, the brake disc 9 has a brake disc main body 13 that is threaded onto the disc wheel 6. A large number of protrusions 15 are formed on the outer circumferential portion of the brake disc body 13 and protrude radially outward and rearward in the rotational direction of the front wheel 4 (arrow A in the figure).

Since the plates can be cut close to each other so as to suppress the friction plates, an improvement in yield can be achieved compared to conventional methods in which friction plates are integrally molded into an annular shape.

As a result, the joint between the adjacent arcuate plates that are inclined toward the brake pad i can smoothly slide. Therefore, in the case where a plurality of arc-shaped plates are formed, even if a slight difference in level occurs at the joint of these arc-shaped plates, problems such as generation of abnormal noise during brake operation can be prevented.
