ヤリパーの改良に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention applies pressure to a friction pad on the rotor using a caliper having a structure in which a hydraulic cylinder is attached to one end of a U-shaped caliper member that straddles the rotor. This invention relates to an improvement of a caliper for a disc brake, which is comprised of a U-shaped part made of steel and a cylinder part made of cast aluminum.

Generally, the caliper of a caliper-type disc brake is made of either ductile cast iron or aluminum casting, but in the case of the former, the material cost is high and the material's Young's modulus is small, so it depends on the hydraulic pressure of the cylinder. The deformation of the U-shaped portion is large, and in order to reduce the deformation, it is necessary to increase the wall thickness, which is disadvantageous in terms of weight and economy. On the other hand, in the case of the latter, the absolute level of weight is lower than in the former, but since the Young's modulus is even smaller, the wall thickness must be increased accordingly, which has the disadvantage of significantly increasing the overall cost.
本発明はこのような欠点を除去すべく提供され

The gist of the present invention is a caliper-type disc brake having a U-shaped caliper that straddles the rotor, which is engaged with a U-shaped portion made of steel and a circular hole drilled at one end of the U-shaped portion. This disc brake caliper is characterized by consisting of a cylinder part made of cast aluminum with an annular groove on the outer periphery, and the assembly of the U-shaped member made of steel and the cylinder part made of cast aluminum is different from the former. It is distinctive in that it is carried out through a circular hole drilled at one end.

１と一体構造としたキヤリパーＡである。 As shown in Fig. 1, a steel material with a large Young's modulus is used for the U-shaped caliper member 1 that straddles the rotor of the disc brake, and the cylinder part 5, which is fixed to one end of the caliper member 1, is made of lightweight aluminum casting. This is what I did. To elaborate further,
As shown in FIG. 2, first, a U-shaped caliper member 1 is formed from a sheet metal, and one end of the caliper member 1 is provided with a cylinder locking hole 3, and the protruding portions 1' on both sides of the hole 3 are provided with caliper slide pins. The caliper A has a holding hole 4, and a cylinder part 5 is cast from aluminum so as to be engaged with the hole 3, and is integrally formed with the U-shaped member 1.

As mentioned above, the caliper A of the present invention uses a press-formed steel plate with a large Young's modulus for the U-shaped member 1, which is susceptible to deformation due to hydraulic pressure during brake operation, and uses an expensive but lightweight aluminum casting. By using this in the cylinder portion 5, it is possible to provide a lightweight caliper with small hydraulic deformation. Further, in the present invention, the U-shaped caliper member 1
The cylinder part 5 is assembled by casting molten aluminum into a steel caliper member as a cylinder part through the combination of the circular hole 3 of the former and the annular groove 3' of the latter. 5
There is no risk of the brakes falling off when braking, and the structure is simple and requires fewer parts.
In addition, unlike conventional products, this disc brake caliper does not require a complicated mold and is extremely practical, as it can reduce processing costs.
