Abstract

PURPOSE:To improve a heat insulating property and a vibration absorbing property and to facilitate machining by forming a rear metal pressing the friction material to a rotor while supporting it in a double plate structure in the width direction at least within the range of the fixed surface of the friction material. CONSTITUTION:A friction pad is comprised of a friction material pressed to a rotor and a rear metal which conveys the pressing force applied by the reaction claw portion of a hydraulic cylinder unit or a caliper to the friction material and presses the friction material while supporting it firmly. In this case, the rear metal is formed in a double plate structure in the width direction at least within the range of the fixed surface of the friction material by bending the metal plate of the rear metal raw material. For example, the rear metal raw material 1 punched in a predetermined shape is bent in two and machined so as to form the rear metal 2 with a double plate structure as a whole. Accordingly, the heat conductivity and vibration property can be improved as compared with those of a single plate structure and also the machining can be made easy.

ある。In general, the friction pad of a disc brake consists of a friction material (generally called a lining) that is pressed against the rotor, and a pressure force applied by a hydraulic cylinder device or a reaction pawl of a carino 9, which is transmitted to the friction material. It consists of a backing metal that presses against the rotor while firmly supporting the material. The former is usually made by hardening and molding metal fibers, natural fibers, etc., or other mixed materials with synthetic resin, and semi-metallic ones are also used. The latter is usually formed by punching a metal plate such as a steel plate.

点が挙げられている。The problems that have been faced in the past when constructing such a friction pad are: firstly, frictional heat is generated on the sliding surface between the rotor and the friction material, and this heat is transferred to the friction pad. If the heat is transmitted to the hydraulic system such as a hydraulic cylinder device through the piston or brake piston, it may cause so-called paper lock, which increases the temperature of the brake fluid in the cylinder. prevention, etc.)
ff: To reduce as much as possible, or by reducing heat conduction, to reduce thermal deterioration of the rubber seal member and improve resistance and manpower.Secondly, to reduce the transmission of vibrations caused by braking to the hydraulic cylinder device, etc. Thirdly, the friction material must be firmly fixed and supported by the backing metal to resist the shearing action on the backing metal caused by the friction material being pressed against the rotor. Points such as:

擦材の接着面に凹凸嵌合部を形成せしめたりする工夫の
施されたものが提案されている。Regarding these various issues, in the conventional friction/9-piece structure described above, since the back metal itself is a member with good thermal conductivity, it is necessary to, for example, apply a heat conductor to the back metal adhesive layer by straining the friction material. In order to prevent vibration transmission, a shim plate to prevent squealing is further interposed on the back of the back metal of the friction pad, and a concave-convex fitting part is provided on the bonding surface of the back metal and the friction material to increase shear strength. There have been proposals for devices that allow the formation of such a structure.

る。However, even if these various ideas were effective for individual tasks, they were either ineffective for other tasks or resulted in a score of 4 points. For example, if the back metal and friction material are placed on an uneven stand, the relatively porous nature of the friction material exposed on the back surface of the back metal may cause water absorption, rusting, and even peeling, as well as separate component parts. There are some problems, such as the need for additional parts, which increases the number of parts to assemble.

Accordingly, it is an object of the present invention to provide a disc brake armature/seventh pad having a backing plate configured to suitably deal with the various problems described above.

A case is shown in which a punched backing metal material 1 (steel plate, etc., omitted hereinafter) is bent in half to form a backing metal 2 having a double plate structure as a whole as shown in Fig. 1←), Figures 2 (() and (b) show that the back metal material 3, which has also been press punched into a predetermined shape, is bent symmetrically at both the left and right M4A (corresponding to both sides in the circumferential direction of the rotor), resulting in a total of two angles. It shows the case where it is formed as a plate-structured back metal 4, and furthermore, Fig. 3 ((), (B), (C)) shows
A case is shown in which a similar back metal material 5 is partially formed with protrusions, and then the entire back metal 6, 6' has a double plate structure (see #3 (c)).

It forms the fixed surface. In addition, although an example in which the engaging hole 8 of the bottle for hanging the bottle is formed and an example in which the engaging hole 8 is not formed are shown separately, these may be formed individually depending on the brake device to which it is applied.

利となる。According to the wear pad with this structure, since the back metal has a double plate structure, the two plate parts (hereinafter referred to as the front plate and the rear plate) are substantially separated by the double layering of the plates. This makes it advantageous in terms of thermal conductivity and vibration performance compared to a single-plate structure.

ないようにしたものを示している。In addition, in the examples shown in Figures (E) and (F), a protrusion is formed on the front plate of the two-mug plate structure, so that the fixed friction material can easily resist the shearing force generated between it and the implant due to the force received during braking. This shows a product that is designed to prevent peeling.

両者の要求を前板のみを加工ｔｔＣ↓って満足できるこ
とになる。It should be noted that such protrusion processing is not necessary on the rear plate of the back metal, and it is better not to process it in order to make the contact surface of the piston that engages with the rear plate one-sided.
Both requirements can be satisfied by processing only the front plate ttC↓.

る。In the example shown in Figure 6, the front and rear plates are brought into contact at multiple points, but this is because a support (not shown) engages with the metal surface of the friction pad to generate a brake torque. This is intended to effectively prevent deformation of the backing plate in cases where the friction material is subjected to pressure, and the engagement is localized to the front plate due to the four defects of the friction material. It is.

*The member inserted between 10m effectively prevents the heat generated on the friction material and the rotor's rhinoceros-engraved engagement surface from being transmitted to the piston side, which is connected to the back surface of the metal Mk metal.
You can always keep in mind the vibration reduction effect of the AlIT plate, and if you use a cutting metal material for the sign, you can use the metal plate between the FiIl plate and the back plate.
Since it is possible to form smoky air based on the shape of the member, it is effective in terms of reduced heat insulation and IJJ absorption. In this example, a part of the different material 13 inserted between the front plate 12 and the back plate 12 of the back plate 12, which has a double plate structure, is
By positioning this extending portion 14 between the back surface of the back plate 12 and the piston 15 that engages with it, the effects of heat insulation and photographic absorption are further enhanced. This is what I did. Note that 16 is the front plate 12 of the back metal 12.
The figure shows the friction material completely stuck to the front.

Compared to the base metal, it has various advantages such as selective processing of only the necessary parts of the back metal, easy insertion of insulation materials such as glass sheets and rubber, and insertion of absorbing materials. Its usefulness is extremely unique.
