Disc structure

This creation relates to the technical field of brake braking, and in particular to an innovative structural type revealer of the disc structure.

For a long time, bicycles have always played a pivotal role in human short-distance movement. In recent years, the trend of energy saving, carbon reduction and leisure has been blown up, making bicycles that do not consume energy and energy are more popular and deeper into every family.

Although bicycles are non-mainstream vehicles, they are equipped with brake devices as well as other vehicles to improve driving safety. Regardless of the type of vehicle, the brake device is an integral part of driving safety. The traditional brake devices are two types of drum brakes and disc brakes. These two brake devices are used to make the blades to rub the brake drum or the brake disc, and then use the increasing friction to achieve the deceleration or The effect of parking. In general, the brake effect of the disc brakes is more reliable than that of the drum brakes. Therefore, the high-grade bicycles on the market or the bicycles with special safety considerations have been greatly adopted by the disc brakes to increase the added value of the bicycles.

However, the conventional disc-type brake structure has found that the following problems still exist in the actual use experience: 1. The structure is complicated: the structure of the disc is too complicated, in addition to the material cost, the assembly cost is also high, of course, consumers buy After returning home, the cost of repairs will of course become higher. 2. In the above, in a limited space, it is necessary to accommodate a complicated structure at the same time. The size of many components must be reduced in size, resulting in a spring wire diameter that provides resilience, so that after the braking action is completed, The speed of resetting the film is slow, causing unnecessary friction and shortening the life of the film. 3. It is not easy to assemble: the assembly sequence of the traditional disc structure is installed from the outside to the inside. Therefore, the working space for the transfer will gradually become smaller as the assembled parts are described. Of course, the assembly difficulty will also follow. Becomes high.

In view of this, the creator has improved the structure and assembly of the above-mentioned conventional disc brakes, and developed a butterfly-type brake with a novel structure, and proposed a new patent case No. 104209130 according to the law, although the case can be To improve the lack of the aforementioned butterfly-type brakes, the design of the structure is still not perfect. The reason is that the spring force providing the restoring force is sleeved on the outer periphery of the first cylinder of the first propulsion column. However, in order to take into account the structural strength of the first propulsion column itself, the diameter of the first cylinder has a limitation. The accommodating space between the first cylinder and the screw sleeve and the screw hole is compressed, which indirectly affects the wire diameter of the spring wire. In contrast, the restoring force that the spring can provide is also limited. Furthermore, depending on the characteristics of the compression spring, the smaller the outer diameter of the spring, the greater the elastic force that can be provided under the condition that the wire diameter is the same. Therefore, if the spring sleeved on the outer periphery of the first cylinder of the first propulsion column is designed to be accommodated in the first propulsion column, the same outer diameter can be used to make the spring of the smaller outer diameter and provide a larger The elastic force will inevitably reduce the cost of the spring.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

The second rotary propulsion structure 723 and the first rotary propulsion structure 713 push the first propulsion column 71 inwardly, thereby driving to urge the piece 60 against the brake disc 40 and compressing the spring 51 for the purpose of deceleration or stopping. When the pulling force provided by the brake line is lost, the restoring force of the spring 51 pushes the first propulsion column 71 and the second propulsion column 72 in the reverse direction to return it to the position before the operation, and at the same time, the piece 60 is also separated from the brake disc. 40 ends the brake deceleration action. The second push column 72 is formed with a receiving hole 724 extending in the axis thereof, and the protrusion 714 is screwed in the receiving hole 724 to maintain the concentricity between the first push column 71 and the second push column 72. .

Efficacy Description: The "disc structure" disclosed in the present application mainly uses the innovative unique structural patterns and technical features of the first and second housings to make the present design contrast with the conventional structure proposed in [Prior Art]. In other words, it mainly uses the space configuration formed in each of the perforations and the screw holes, and then the use of the screw sleeve can simplify the structure of the traditional disc brake, and at the same time, the assembly direction of the disc structure is assembled by the traditional inner side. Changing to the outer assembly can greatly reduce the assembly difficulty of the disc structure. Furthermore, since the screw hole must be locked with a screw sleeve, the space between the housings is formed in the first propulsion column when the same specification structure is installed. The space is larger than the traditional disc structure, so it can be used (installed) with a large diameter spring, and provides a strong propulsion force and a faster reset speed, so it can provide accurate braking effect and quick reset action. It can be extended to make the life of the film. Therefore, this creation has a novel structure and functional enhancement compared to the traditional dish structure.
