Description

Sprocket structure with disc

This creation is related to the disc brake system, especially a sprocket structure with discs.

Brake calipers are commonly used in vehicles that use disc brake systems as brakes, such as automobiles and motorcycles. The conventional brake caliper has a caliper body, two pads and two pistons. When the driver steps on the brake pedal or presses the brake handle At the same time, the piston in the brake caliper is driven hydraulically to push the disc to clamp a brake disc, and the brake disc is stopped by friction, thereby stopping the rotation of the tire.

The above-mentioned common disc brake systems are often applied to a single brake disc. However, with the continuous advancement of technology, the engine power of automobiles and motorcycles has become more and more powerful. When a locomotive is running at high speed, relatively high braking performance is required to ensure driving safety and provide vehicle stability. At this time, if only a single brake disc is used for braking, the above objective may not be achieved.

In order to solve the above-mentioned problems, a dual-disc brake system has also been developed and designed, but the conventional dual-disc brake system only arranges the common single caliper bodies side by side, which is relatively large. In the case of locomotives, most of them can only be installed on the front wheels of the locomotive, and the rear wheels of the locomotives can only be installed with a single brake disc, which makes the braking performance of the front and rear wheels prone to imbalance, so how to improve the braking performance of the locomotive And to solve the problem of brake balance, it is a problem that needs to be overcome at present.

Therefore, how to develop a more ideal and practical innovative structure in response to the above-mentioned problems in the braking performance of locomotives is also the goal and direction that the relevant industry must strive to develop and break through.

It can be seen that there are still many shortcomings in the above-mentioned conventional brake structure, which is not a good designer and needs to be improved urgently.

In view of the various shortcomings derived from the above-mentioned conventional brake structure, the creator of this case is eager to improve and innovate, and after years of painstaking research, finally successfully completed the development of this sprocket structure with discs.

The purpose of this creation is to provide a sprocket structure with discs.

At present, the common heavy-duty locomotives mostly drive the rear wheels to rotate through the cooperation of sprocket and chain. Although the rear wheel has a disc brake system, it is only installed on the other side of the sprocket to form a single-disc brake system. ; However, with the increasing power, if there is only a single-disc brake system, the overall braking force may be insufficient, which will affect driving safety.

In order to achieve the purpose of this creation, the sprocket structure with discs in this creation includes a sprocket, which is arranged on the driving wheel (such as the rear wheel of a locomotive). A disc is provided on both sides of the sprocket, and the disc A heat dissipation gap is formed between the disc and the sprocket, and the disc and the sprocket can be connected in an integrated manner or assembled.

In addition, in order to reduce the volume, only a single disc can be integrally formed between the sprockets, and the same effect as the above structure can also be achieved.

When the sprocket of this creation is set on the driving wheel, it can cooperate with a brake caliper to form a disc brake system, and match the original disc on the other side to form a double disc. The brake system of the disc effectively improves the braking performance and driving safety.

In order to make the above and other purposes, features and advantages of this creation more obvious and easy to understand, the following specifically enumerates the preferred embodiments, in conjunction with the accompanying drawings, which are described in detail as follows.

Please refer to the first to fourth pictures, the sprocket structure with discs of this creation includes:

A sprocket 1 is arranged on the driving wheel. In this embodiment, it is arranged on the rim of the rear wheel of the locomotive. The sprocket 1 is formed with a plurality of sprocket teeth 11 on its periphery, so that it can mutually tooth with the chain 3 Close, and drive the sprocket to rotate through the chain 3;

A plurality of discs 2 are respectively arranged on both sides of the sprocket 1. In this embodiment, the sprocket 1 and the disc 2 are integrally formed, and a space is formed between the disc 2 and the sprocket 1. The heat dissipation gap 21. Furthermore, the structure of the disc 2 can be a conventional ventilated disc. Therefore, a plurality of air guide fins 22 are provided between the heat dissipation gap between the disc 2 and the sprocket 1, and the disc 2 2 on A heat dissipation hole 23 is provided for providing heat dissipation effect. It is only necessary to pay special attention that the disc 2 is not limited to a ventilated disc, and it can also be a solid disc.

Please refer to Figure 5, which is a schematic diagram of the implementation of this creation set on the driving wheel (rear wheel of a locomotive). The sprocket 1 of this creation is set on the drive wheel and driven by the toothing of a chain 3 to make the rear wheel Driven to rotate, the frame is provided with a brake caliper 4, which can be arranged outside the disc 2 on both sides of the sprocket 1, and the disc can be clamped and rubbed by the disc The deceleration further forms a disc brake system, which effectively improves the braking performance.

In addition, when the brake is activated, the high temperature generated by the disc 2 can be dissipated through the heat dissipation gap 21 and the heat dissipation hole 23, which can prevent the sprocket 1 from affecting its transmission performance due to high temperature, and further avoid the deformation of the sprocket 11 .

Please refer to the sixth figure. In this embodiment, a plurality of fixing holes 6 are provided on the disc 2 and the sprocket 1 at corresponding positions, and the fixing holes 6 are connected by plural numbers. The arrangement of the piece 5 allows the disc 2 to be fixed on the sprocket 1. The connection arrangement of the connecting piece 5 not only achieves the same braking effect as the above embodiment, but also provides convenience for the replacement of the disc 2 when worn It can also further reduce the cost of maintenance and replacement.

Please refer to Figure 7 again. In this embodiment, the disc 2 is formed integrally with the sprocket 1 and is accommodated between the sprocket 1. This structure can reduce the amount of the sprocket 1. The volume is further applied to the driving wheel with limited accommodating space. In addition, since this structure only includes one disc 2, the production cost will be relatively low, which can expand the application range and field.

The above detailed description is a specific description of a feasible embodiment of this creation. However, this embodiment is not used to limit the scope of patents of this creation. Any equivalent implementation or modification that does not deviate from the spirit of this creation technique should be included in In the scope of the patent in this case. The right protection of this creation The scope should be as described in the scope of patent application described later.
