本考案はブレーキのライニング摩耗警報装置に
関する。より詳しくは、ばね性警報接片を利用し
たライニング摩耗警報装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a brake lining wear warning device. More specifically, the present invention relates to a lining wear alarm device that uses a spring alarm contact.
［従来技術］
ブレーキ・ライニングの摩耗が使用限界に達し
たとき可聴音を発生させて運転者にライニングの
交換時期を知られせるライニング摩耗警報装置に
関して、従来から、種々の提案がなされており、
そのひとつとして、ばね性警報接片を利用したラ
イニング摩耗警報装置が知られている。[Prior Art] Various proposals have been made in the past regarding lining wear warning devices that generate an audible sound when the wear of the brake lining reaches its service limit to notify the driver that it is time to replace the lining.
One known example is a lining wear alarm device that uses a spring alarm contact.
この種のライニング摩耗警報装置は、リムの周

部を経て延びる該警報接片の自由端部をリムのラ
イニング貼着側に突出させ、警報接片の摺接縁が
ライニングの使用限界の位置に適合するように構
成されている。 This type of lining wear warning device has a spring alarm contact piece attached to the end of the rim in the circumferential direction, and a free end of the alarm contact piece extending through the bent portion protrudes toward the side of the rim where the lining is attached. The sliding edge of the alarm contact piece is configured to match the position of the lining's use limit.

運転者はこの異音を聞くことにより、ライニング
が使用限界まで摩耗したこと知ることができる。 With this configuration, when the lining wears down to its usable limit, the sliding end (the end of the part protruding from the rim) of the spring alarm contact, which had been retracted from the lining, will protrude from the lining. As a result, when the brakes are applied, this comes into contact with the inner circumference of the drum, causing an abnormal noise.
By hearing this abnormal noise, the driver can know that the lining has been worn to the limit of its use.

ことを第２の特徴とする。 That is, the first feature is that the alarm contact piece can be easily attached and detached by utilizing the springiness exhibited by the bent portion of the spring alarm contact piece. on the other hand,
Among the displacements of the spring alarm contact piece after insertion, displacement in the rim width direction is regulated by engagement between the web and the legs of the alarm contact piece extending across the web. In addition, the displacement in the radial direction is regulated and positioned by the engagement between the insertion part of the alarm contact piece and the reception recess of the shoe that matches the thickness of the insertion part, and the displacement in the circumferential direction is determined by The positioning is controlled by the cooperative action of the elastic contact between the back surface of the bent portion and the end edge of the web, and the engagement of the tongue piece provided in the leg portion of the alarm contact piece and the rim with the hole. The second feature is that this makes it possible to fix the position of the spring alarm contact after insertion, that is, to ensure the insertion of the spring alarm contact in addition to the ease described above.
