【考案の詳細な説明】
この考案は自動車のブレーキ装置を構成するブ
レーキシユーに関する。[Detailed Description of the Invention] This invention relates to a brake shoe constituting a brake device for an automobile.
自動車が急停車する場合等しばしば鋭い音を発
する。ブレーキドラムにブレーキシユーを押圧し
てブレーキする場合、ブレーキシユーが振動する
ことによる振動音で、いわゆるブレーキの「鳴
き」である。この発明は「鳴かない」ブレーキシ
ユーを提供することを目的としている。 A sharp sound is often emitted when a car suddenly stops. When a brake shoe is pressed against a brake drum to apply the brakes, the brake shoe vibrates, producing a vibration noise that is called brake squeal. The purpose of this invention is to provide a brake shoe that does not make noise.
ブレーキの鳴き防止機構を設けたブレーキシユ
ーに関する考案として、実公昭49−39755号並び
に実開昭54−140186号公報記載の考案がある。 As an idea for a brake shoe equipped with a brake squeal prevention mechanism, there are ideas described in Japanese Utility Model Publication No. 49-39755 and Japanese Utility Model Application Publication No. 54-140186.
実公昭49−39755号の考案は、ブレーキシユー
のライニングが最初にドラムに接触する部分に、
Ｌ型に形成した押え板を固着するように構成され
ている。つまり、前記部分が最大の振動を提する
との前提に立つて、この部分に振動吸収材を固設
して、鳴きを防止しようとする。 The idea of Utility Model Publication No. 49-39755 is that the lining of the brake shoe first contacts the drum,
It is configured to fix an L-shaped presser plate. That is, on the premise that the above-mentioned part exhibits the maximum vibration, a vibration absorbing material is fixedly attached to this part in an attempt to prevent squealing.
また実開昭54−140186号の考案は、シユーのブ
レーキドラム開口側内周面に制振材を接合して鳴
きを防止しようとする。 Moreover, the invention of Utility Model Application Publication No. 140186/1986 attempts to prevent squeal by bonding a damping material to the inner circumferential surface of the shoe on the opening side of the brake drum.
前者の考案では最大振巾点に押え板を固設する
ため、シユーの振動系が変り、押え板を固設した
後は、この点に最大振巾が生じなくなるので充分
な鳴き防止ができない欠点がある。 In the former design, the holding plate is fixed at the point of maximum swing, which changes the vibration system of the shoe, and after the holding plate is fixed, the maximum swing does not occur at this point, so it cannot sufficiently prevent squealing. There is.
また後者の考案では、ブレーキシユー自体が必
要以上に重くなり、実用に供し難い欠点がある。 Furthermore, the latter idea has the disadvantage that the brake shoe itself becomes heavier than necessary, making it difficult to put it to practical use.

のでは押付け場所の選択が極めて困難である欠点
を包含している。 Also, unlike the above two, a suitable number of discontinuous weights are provided on the outer periphery of the bucking plate, and this weight also has a damping effect due to friction with the bucking plate. There is
No. 46567). In other words, the weight itself is curved into an arc,
The center part is pressed to fix it to the bucking plate, and both edges are strongly pressed to the bucking plate to prevent slippage caused by the strong friction between the both edges of the weight and the bucking plate. It is formed to attenuate as a result. However, brake squeal during braking is caused by vibration of the shoe itself caused by strong mutual pressure contact between the lining provided on the outer surface of the shoe rim and the inner peripheral surface of the rotating brake drum. There is an inherent drawback that brake squeal cannot be sufficiently prevented only by damping the resonance of the bucking plate. In addition, pressing only the edge of the weight has the disadvantage that it is extremely difficult to select the pressing location.

するものである。 This idea was originally proposed by the applicant in 1974.
An improvement on the idea of No. 139224, a curved friction plate is provided at the node of the shoe's vibration when the brake is applied, and the relative slip between the shoe's vibration surface and the contact surface of the friction plate is increased to reduce vibration. The object of the present invention is to provide a brake shoe that absorbs energy and effectively prevents brake shoe squeal.

The web 2 of the brake shoe is a rim of the brake shoe, 3 is a lining, and 4 is a friction plate according to the present invention. Numerals 5 and 6 are studs for fixing the friction plate 4 to the brake shoe. As shown in FIG. 2, the friction plate 4 is formed by curving a friction plate main body 41 made of a flat plate with a rectangular cross section into an arc shape, and a mounting portion 42 fixed to the web 1 is formed into a linear shape. At the same time, the friction portion that contacts the edge portion of the inner surface of the rim with mutual pressure is also formed into a curved beam with a slightly straight portion so as to provide a width-like contact portion 43.

As disclosed in the applicant's Utility Model Application No. 140186/1986, the brake shoe vibrates when the brake system is operated. Provided at points that form vibration nodes.

と共に減衰効果を併有させるように形成する。 In other words, the brake shoe in a vibrating state has a length corresponding to approximately 1/4 of the total length of the arcuate curved periphery of the rim 2 from both side edges of the rim 2 as a node, and a position in the center and on the rim 2. It vibrates with the edges on both sides as antinodes. Near the inner peripheral edge of the web 1 at this vibration node, a mounting portion 42 of a friction plate 4 whose side surface is formed into an arc-shaped curved shape following the web 1 and whose cross-sectional shape is curved is fixed, The contact portion 43 having a flat edge portion of the friction plate 4 fixed at a non-vibrating point is brought into contact with the inner surface edge portion of the rim 2 having a large amplitude so as to have both a braking effect and a damping effect. to form.

状に形成する。 Depending on the type of vehicle equipped with this brake device, the cross-sectional shape of the friction plate 4 may be changed between the mounting portion 43 and the mounting portion 43, as shown in FIG. It is formed into a truncated triangular shape tapering toward the contact portion 43.

成する。 In addition, the contact portion 43 due to vibration of the brake shoe 1
In order to eliminate local vibrations and maintain a larger relative slip, the cross-sectional shape of the friction plate 4 is tapered from the contact portion 43 toward the attachment portion 42, contrary to the previous embodiment. Form into a truncated triangular shape.

抑制する。 In any of the above cases, the attachment portion of the friction plate main body 41 formed at one end of the curved beam is fixed to a vibration node near the inner peripheral edge of the web 1. In this case, the web 1 and the rim portion 2 vibrate together and have the same "nodes" and "antinodes." However, the neutral line of this vibration exists on a line that is slightly closer to the attachment part 42 than the inner edge of the rim part 2 in FIGS. 1, 2, and 3, that is, on a parallel line that is closer to the inner edge of the rim part 2 at the node. . In other words, even at the nodal point of the shoe's vibration, the friction plate main body 41 fixed to the inner peripheral edge of the web 1 belongs to a vibration system different from the web 1 and the rim 2, but the vibration is the same as that of the inner peripheral edge of the web 1 at the nodal point. This causes a relative slip on the contact surface of the rim portion 2. Further, at the antinode, a large relative slip occurs on the abutting surfaces, suppressing the vibration of the shoe as a whole.

に「鳴き」を防止することができる。 This invention is constructed as claimed in the utility model registration based on the above-mentioned embodiment, so that the elastic pressing force of the friction plate and the solid friction between the edge of the inner surface of the rim and the contact area of the friction plate are synergistic. Brake shoe squeal can be prevented. Furthermore, since the friction plate is fixed to the so-called "knots" of the brake shoe, the relative slip on the contact surface becomes large, and therefore "squeal" can be effectively prevented.

This embodiment has the practical benefit of absorbing a large amount of energy and increasing the rigidity of the rim periphery.
