Construction of double-layer brake disc

The present invention relates to a double-layer brake disc structure, in particular to a plurality of corresponding heat dissipation holes for a double-layer brake disc; connecting the connecting member to the heat dissipation hole position of the two friction plates, and forming a heat dissipation The channel can improve the bonding strength and heat dissipation effect, and at the same time, it has light weight and can be quickly produced by stamping.

The steam locomotive is the most important transportation tool today. It has the advantages of fast driving speed and high maneuverability. With the development of steam locomotives, the sense of distance between the two places is shortened, and people's living circles are expanded. However, the steam locomotive is driving at high speed. In order to cope with various emergencies on the road, the most important safety mechanism is the brake mechanism that can stop the steam locomotive at any time.

The principle of steam locomotive braking is to use the film to clamp the brake disc, and the friction between the two can quickly convert the kinetic energy of the locomotive into heat dissipation, and stop the locomotive.

It can be seen from the foregoing description that the brake disc needs to withstand extremely high friction and therefore needs sufficient strength. And converting the kinetic energy of the high-speed driving of the steam locomotive into thermal energy is bound to make the brake disc need to withstand high temperature. Therefore, the high structural strength and high heat dissipation speed are the two most important characteristics of the brake disc.

The brake disc structure is, for example, the "brake disc" of the Republic of China Patent No. I274818. The case discloses that there are a plurality of fins between the inner and outer edges of the surface of the disc, and at least one pair of fins has a plurality of flow passages. Each flow channel includes a first flow channel opening, an inlet near the central portion, and a second flow channel opening adjacent the periphery of the brake disk as an outlet. Through the arrangement of the aforementioned flow channels, the heat convection effect is more obvious, and the heat dissipation speed is faster. There is also a "Lightweight brake rotor with a thin, heat resistant ceramic coating" in U.S. Patent No. 5,224,572, which discloses a light-duty and ceramic-coated heat-dissipating brake disc, and the case discloses "a plurality of circumferentially spaced The spaced cooling aperture means that there are a plurality of cooling holes arranged in the circumferential direction to accelerate the heat dissipation speed.

The two friction plates are separated by contact, and the friction surfaces of the two friction plates are recessed to form a concave portion by punching at the position of the spacer block.

Further, the aforementioned connector types have the following two types:

1. punching the connecting member on one of the friction plates, the connecting member is located on the spacer block and at the periphery of the heat dissipation hole, and the connecting member protrudes from the heat dissipation hole of the other friction plate to the friction of the other friction plate Further, the end portion of the connecting member is bent to form a concave portion of the bent portion against the friction surface of the other friction plate.

2. The connecting member has a cylindrical shape, and the connecting member is inserted into the heat dissipating holes of the two friction plates, and then the two ends of the connecting member are bent to form a bent portion to abut against the concave portion of the friction surface.

Further, at least one of the friction plates is provided with at least one through hole, and when the two friction plates are correspondingly connected, one or more other gaps are formed between the two friction plates at the periphery of the through hole to communicate with the hollow region.

Further, the aforementioned connecting member is coupled to the position of the heat dissipation hole of the two friction plate portions.

Further, a spacer is disposed at a central position between the two friction plates.

The advantages of this creation include:

1. Connect the connecting member to the position of the heat dissipation hole of the two friction plates, and form a heat dissipation channel between the heat dissipation holes of the two friction plates, thereby improving the bonding strength and heat dissipation effect of the two friction plates, and simultaneously forming a plurality of hollow heat dissipation. The channel has the advantage of being lightweight.

2. The two friction plates of the double-layer brake disc can be produced and combined once by stamping, and the production speed is fast.
