Abstract

PROBLEM TO BE SOLVED: To simultaneously provide both advantages of a servo effect provided by a conventional drum brake and a high radiation effect provided by a disc brake. SOLUTION: This system is formed of a ventilated ring 1 formed of a rotary disc 2 and a ring plate 3 having partitioning plates 4 and air holes 5 with double plates structure, a friction material 6, and a friction material 7. Both the outer wall and inner wall of the ring plate 3 of the ventilated ring 1 are simultaneously nipped by the friction material 6 and the friction material 7, respectively, and pressure-connected thereto to stop the rotation of the ventilated ring 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake device,
Ventilated ring brake system that can be used as a stopping device for rotary motion in all fields.

[0002]

2. Description of the Related Art Conventional braking devices mainly include a drum brake system with a high servo effect and a disc brake system with a high heat radiation effect. In the drum brake system, the heat radiation effect is poor and a fade phenomenon or The braking effect in continuous use is low due to the effect of thermal expansion. In the disc brake system, the servo effect cannot be obtained, and the braking effect in the low speed range is low.

[0003]

However, the conventional braking systems of both types cannot solve their respective drawbacks due to the structural reason that they are constructed.

[0004]

In consideration of these points, the advantages of both can be provided by adopting a structure incorporating structural elements obtained by both. In other words, by having a structure that has a drum surface that obtains the servo effect (self-boosting) and also has a friction surface of a two-layer structure that has partitions that enhance the heat dissipation effect, and crimping them with a friction material, To solve the problem, a ring-shaped plate 3 having a two-part structure and a radial partition plate 4 in the gap is provided on the outer periphery of the rotating disk 2 to form a ventilated ring, which has a structure of both sides. The braking system has a dynamic element.

[0005]

Thus, according to the present invention, as shown in FIG. 1, a ring-shaped structure having a two-piece structure on the outer circumference of a rotary disk 2 which rotates about an axis and a ventilation hole 5 is provided in the gap by a radial partition plate 4. The outer wall of the ring-shaped plate 3 of the ventilated ring 1 having the plate 3 of 3 is the friction material 6, the inner wall of the ring-shaped plate 3 is the friction material 7, and both friction materials are in the direction of arrow a. Then, they are pressed at the same time, and by the force, they are pressed against each other by sandwiching both wall surfaces of the ring-shaped plate 3 to rub. As a result, the friction material 6 is attached to the wall surface of the ring-shaped plate 3.
7 is sucked and the servo effect is also obtained, and the rotary kinetic energy is converted into heat energy, and the ventilated ring 1
Stop the rotation of. When the friction materials 6 and 7 are separated from both the wall surfaces, the pressure contact is released and the ventilated ring 1 can be rotated again. The degree to which the friction materials 6 and 7 are sucked on each wall surface of the ring-shaped plate 3 varies depending on the positions of the left and right force points and the fulcrums that press the friction materials 6 and 7. Figure 1 shows 2
This is a diagram of a leading trailing type, in which both friction materials are simultaneously extruded in the direction of arrow a with the left and right as force points, where the servo effect can be obtained by forward and reverse rotation braking. The generated frictional heat is forcibly air-cooled by the partition plate 4 and the ventilation hole 5 of the ring-shaped plate 3 having a two-layer structure by the rotation of the ventilated ring 1 and is obtained by the disc brake. Obtains high braking effect in continuous use.

[0006]

[Example] The rotary disk 2 constituting the ventilated ring 1 has a strong rotary disk so that the rotary disk 2 is not twisted because frictional resistance to both wall surfaces of the ring-shaped plate 3 increases. Do. The cooling capacity is enhanced by considering the gap width of the ring-shaped plate 3 and the mounting angle of the partition plate 4. Also, depending on the purpose of use, the servo effect with each characteristic was obtained by considering the positions of the force points and fulcrums that push the brake shoe with friction material, and the structures and configurations such as the wheel cylinder and piston floating that push them out. It becomes a ventilated ring brake system. FIG.
Then, the brake shoes attached to the friction material, the push-out operation device, the return device, etc. are omitted for the sake of convenience of explanation, and the size, attachment position, number, materials, etc. of the parts of each part constituting the whole are omitted. , Ventilated ring brake system that is optimal depending on various purposes in practice.

[0007]

As described above, by eliminating the drawbacks of the conventional drum brakes and disc brakes, a device having the advantages of both can be obtained, and a braking effect that has not been obtained until now can be obtained, so that it can be used from bicycles to large automobiles. It is a new braking system that can be used for braking devices in various other fields.
