Definitions
- the present invention relates to a brake shoe excellent in mass productivity and cost, and a method for manufacturing the brake shoe.
- a lining material used in combination with a shoe main body for a brake shoe used in a drum brake for a vehicle includes a base material, a lubricant, a friction modifier, a binder, and a filler.
- the lining material usually uses phenol resin as a binder, and after dry mixing, it is preformed and thermoformed into an arc shape, and only the lining is passed through a heat treatment process for curing and a polishing process for finishing. I'm making it.
- the lining is pressure-bonded to the main body of the shoe through an adhesive, and then subjected to further heat treatment to produce a brake shoe.
- Patent Document 1 describes a method for obtaining a belt-shaped friction material having a constant thickness by kneading a mixture for a friction material containing a water-soluble thickener and water into a clay by kneading with a mixer and then extruding the mixture with an extruder. Is disclosed. In this method, however, the belt-shaped friction material is then cut into a predetermined length, the cut material plate is formed into a curved plate, and the formed material plate is formed into a weight body corresponding to the shaw body. Since the joining method is adopted, the number of processes increases because the forming process of the material plate and the bonding process to the weight body are separated.
- Patent Document 2 integrally forms a shoot body and a temporarily formed lining, and at that time, temporarily forms a lining of a temporary molded product, and cures at the same time as forming, and bonds the lining to the shoot body.
- this method is a method of temporarily forming a lining and Since it adheres to the body, the press process for temporary molding increases.
- Patent Document 1 Japanese Patent Laid-Open No. 2003-156090
- Patent Document 2 Japanese Patent No. 3677235
- an object of the present invention is to provide a brake and a brake shoe manufacturing method that can be manufactured with a reduced number of processes.
- an extrusion-molded or calender-sheet-formed lining material sheet is cut into a strip having a predetermined length to form an arc shape and stacked on a main body of a shoe. Then, it is cured after being molded and bonded integrally with the main body. As a result, a brake shoe in which the shoe main body and the arc-shaped lining are integrated is obtained. Since the brake lining is formed on the shoe main body by a mold, a taper for mold release is formed at both ends.
- the binder contained in the material composition of the lining may be rubber or a material mainly composed of rubber.
- the rubber used as the binder is ebony by vulcanization. If rubber containing 20 to 40 parts by weight of sulfur is used per 100 parts by weight (phr) of rubber, the rubber will be ebonyized by the vulcanization process.
- the types of rubber used include butadiene rubber (BR), styrene rubber (SBR), nitrile rubber (NBR), and isoprene rubber (IR).
- Gen rubbers such as natural rubber (NR) can be used if the heat resistance requirement is not high.
- the binder may be a combination of a rubber that is ebonyized by vulcanization and a thermosetting resin such as phenol resin.
- the raw material sheet for lining formed by extrusion molding or calender sheet is cut into strips of a predetermined length and stacked on the shear main body, and this is used as a molding die for the molding machine.
- Brake shoe manufacturing method in which the upper die and the lower die are clamped to form an arc shape and a taper for punching is formed at both ends. Also provided. According to this manufacturing method, it is possible to obtain a brake shoe in which an arc-shaped lining is adhered to the outer periphery of an arcuate main body without the arc-forming step prior to the lining.
- the brake shoe and the method of manufacturing the brake shoe according to the present invention are formed by integrally forming a lining material sheet which has been extruded or calendered and cut into a predetermined length and then cured into a body before curing. Because it adheres to the main body, there is no need to shape the lining into an arc in advance. Therefore, the molding process is reduced, and the lining polishing process is also reduced, thereby improving productivity. In addition, labor and energy consumption can be reduced by reducing processes.
- FIG. 1 is a side view showing an example of a brake shoe according to the present invention.
- Figure 2 Front view of the brake shoe shown in Figure 1
- FIG. 3 is a diagram showing a manufacturing process of the brake shoe of the present invention.
- the brake shoe 1 includes a shoe body 2 and an arc-shaped lining 3 bonded to the outer periphery of the shoe body 2.
- the shear main body 2 is composed of a rim 2a bent into an arc shape and a web 2b joined to the inner periphery of the rim, and a lining 3 is bonded to the outer periphery of the rim 2a.
- the lining 3 is formed of a composition in which a base material, a lubricant, a friction modifier, a filler, and a binder are mixed.
- the base material, the lubricant, the friction modifier, and the filler may be materials employed in general friction material compositions.
- fiber base materials such as metal fibers, synthetic resin fibers, and inorganic material fibers are used as base materials, and graphite and the like as friction materials include friction modifiers and fillers.
- Metal oxides, metal salts (such as barium sulfate), and organic powders (such as ash dust) are used as these.
- the material of lining 3 of this invention may be such.
- the binding material is not a general one but a rubber or a material mainly composed of rubber.
- gen-based rubbers such as butadiene rubber (BR), styrene rubber (SBR), nitrile rubber (NBR), isoprene rubber (IR) and natural rubber (NR) can be used.
- this rubber is used with 20 to 40 parts by weight of sulfur added to 100 parts by weight of rubber.
- the rubber to which a large amount of sulfur is added becomes ebony and hardened by the vulcanization treatment, so that the heat resistance and wear resistance required for the lining can be sufficiently ensured.
- Rubber can be added using a general method of rubber kneading. For example, it can be added using an open roll, a bun nori mixer, a pressure kneader, an etastruder or the like.
- thermosetting resin such as phenol resin may also be used as a binder!
- the composition used as a lining material is kneaded and extruded or calendered with an extruder 6 to obtain a material sheet 3A having a constant thickness.
- the calender sheet is formed using a calender roll machine 12 as shown in FIG.
- the calendar roll machine 12 shown in the figure is configured by vertically arranging three rolls 12a to 12c. Materials are sequentially passed between the rolls 12a and 12b and between the rolls 12b and 12c. Obtain material sheet 3A.
- the material sheet 3A is cut into strips of a predetermined length by a cutting machine 7 and molded with the main body 2 Send out toward the bonded part. Also, the end material after punching out a strip of a predetermined size from the material sheet is reused for extrusion molding or calendar sheet molding again.
- the preparation main body 2 that has been prepared is applied to the outer peripheral surface of the rim 2a with an adhesive and set in the mold of the molding machine, and a strip is formed on the outer peripheral surface of the rim 2a.
- Put material sheet 3A cut into a shape and pressurize and heat mold it.
- the shear main body 2 becomes a molding mold and the material sheet 3A extends along the outer peripheral surface of the rim 2a. Bend and adhere to the rim. Bonding is also performed at the same time by heating during molding.
- the molded main body and the material sheet 3A are introduced into the furnace 9 and subjected to heat treatment for curing the lining. Finally, the lining 3 is polished with a polishing machine 10 and finished to make a finished product.
- FIG. 4 shows a conventional method for manufacturing a conventional brake shoe shown for comparison.
- the manufacturing method of the present invention is completely different from the conventional method, but there is a clear difference in the manufacturing process of the lining.
- the manufacturing method of the present invention the bending process of the lining and the adhesion to the shoe body are simultaneously performed, so that the pressing process is reduced to one time. Also, the polishing of the lining before bonding is omitted and the polishing process is reduced to one.
