Abstract

PURPOSE:To obtain a lightweight inexpensive cast wheel, by providing a plurality of respective torque locks on a bracke drum and a bearing boss which are welded to each other, and fixing the brake drum to a cast wheel rim with molten metal. CONSTITUTION:A brake drum 2 is formed by pressing a steel plate and providing torque lock portions 7, 9 and 10 at plural positions of the pressed steel plate. A boss 1 is fitted in a central portion of the brake drum 2, and is fixed to the brake drum 2 at a welding portion 6. Then, the welded member is die-cast to produce a cast wheel having a rim 3 and a spoke 4 which are integrally formed. According to this method, it is possible to easily obtain a cast wheel which is strong, light-weight and inexpensive.

る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a cast wheel in which a brake drum and a bearing boss are fixed by bath bonding, and a flake tram and a wheel rim are fixed by molten metal. The purpose of this was to manufacture cast wheels at low cost as well as at the same time.

めになされた・ものである。Conventional wheel knobs are made by molding a cast iron ring on the brake drum, whitening it, and casting the same material into a boss part, which is then implanted into a fixed mold placed in a casting machine, and a movable mold. After mold matching and mold clamping, pour the aluminum die-casting from the sprue and take out the cooling sample 9. After casting, the inner and outer diameters of the bearing, the drum +79 diameter, and the rim fitting part are machined and finished, and furthermore, in order to integrate the rim and the wheel hub, assembly work is performed by tightening bolts. That is, as mentioned above, after casting, q) processing and finishing the inner diameter of the drum, assembling and finishing the wheel rim, and assembling the wheel and rim by attaching bolts, etc. has the disadvantage of high manufacturing costs, and furthermore, in the case of a steel plate wheel hub. However, the present invention has the disadvantage that when an internal pressure brake is applied to a structure that is bent by the drum breakage and the welded muscle on the spoke side, the phenomenon of flake noise occurs. This was done to improve these shortcomings.

点も解消するなど多くの効果を奏する。The present invention will be described below with reference to the drawings. The cast wheel of the present invention is shown in FIG.
- Shown in Figure a. In Fig. 1-a, the brake drum 2 is formed by press-molding a steel plate, and has torque prongs 7, 9, and 9 at multiple locations. The brake drum 2 is fitted with a bosse whose inner and outer diameter finishing blades are finished using a copper phase at the center of the drum, and the wheel hub welded at the welding part 6 is fixed to a die-casting machine. After the movable mold is placed in a mold and the mold is clamped, molten metal is poured through the sprue, and after cooling, an integrated wheel is obtained. The brake drum boss to be implanted in this manufacturing method is press-finished before implantation. Even if casting is performed with one-stroke finishing, there is no need to perform one-stroke finishing after that, and the outside of the brake drum is finished with a die gas one-stroke finish. The VC1 strength also increases because of the grains. Furthermore, since it is a cast wheel, there is no need for thread 1-6 thread bolts, which has excellent effects such as weight reduction. Along with this light weight ratio, the manufacturing cost can also be reduced. It also has many effects, such as eliminating the drawbacks of dual brakes.
