Description

Technical Field

[0001] This utility model relates to the field of motorcycle braking system technology, and in particular to a front disc brake assembly. Background Technology

[0002] As a widely used mode of transportation, motorcycle safety is of paramount importance, and the braking system is one of the core components ensuring safety. Disc brake systems, due to their stable braking performance and excellent heat dissipation, have become the mainstream configuration for motorcycle front wheel braking. The brake disc (or disc brake disc) is the component in this system that directly rubs against the brake pads, and its performance directly affects the overall braking effect of the motorcycle.

[0003] Currently, common motorcycle front disc brake discs on the market are typically steel discs with ventilation slots, or discs with a few simple heat dissipation holes. These structures can achieve heat dissipation and weight reduction to some extent. However, with the continuous improvement of motorcycle performance and the increasing demands of users for braking performance and safety, existing brake disc technology has gradually revealed the following shortcomings: The heat dissipation efficiency is still insufficient: traditional heat dissipation hole designs are simple, lacking effective heat conduction connections between holes, and the heat dissipation area is limited. During continuous, frequent, or high-intensity braking (such as long slopes or aggressive driving), the large amount of heat generated by friction cannot be quickly dissipated, easily causing the brake disc temperature to rise sharply, triggering the "heat fade" phenomenon of braking force, that is, a significant decrease in braking performance, which seriously threatens riding safety.

[0004] The contradiction between structural strength and heat dissipation design: In pursuit of better heat dissipation, excessive opening or thinning of the disc may weaken the overall structural strength of the brake disc, especially in critical areas such as the edge of the disc and the mounting position, which poses potential structural risks and affects its service life and reliability.

[0005] Wind resistance and noise issues: Brake discs rotate at high speeds with the wheels during vehicle operation, and their structural design creates resistance to airflow. The shape design of traditional brake discs is not fully optimized for wind resistance, which not only increases driving resistance and affects vehicle power and fuel economy, but may also produce unpleasant wind noise or whistling sounds in some situations.

[0006] Installation alignment difficulties: When installing brake discs, the mounting holes on the disc body need to be precisely aligned with the screw holes on the wheel hub before bolts can be inserted for fixation. This process usually requires manual support and alignment by the operator, which is often cumbersome without auxiliary positioning, especially in confined spaces or with poor visibility, reducing the efficiency of maintenance and installation.

[0007] Therefore, there is an urgent need in this field for a new type of front disc brake assembly that can effectively improve heat dissipation to prevent heat fade, optimize wind resistance while ensuring structural strength, and simplify the installation process, thereby comprehensively improving the braking safety and ease of use of motorcycles. Utility Model Content

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A front disc brake assembly includes a disc body with mounting holes for securing it to a wheel hub. Its improvement lies in: The outer periphery of the disk is provided with a plurality of heat dissipation holes evenly distributed, and adjacent heat dissipation holes are connected by heat dissipation grooves to form an efficient heat dissipation channel. The disc body is provided with a magnetic reinforcing rib in the area of ​​the mounting hole, which uses magnetic adsorption to facilitate quick alignment and installation with the iron screw holes on the wheel hub. In addition, the disc body is also provided with weight-reducing grooves to reduce the overall weight, air vents to reduce rotational wind resistance, and heat dissipation vents to further enhance the heat dissipation effect.

[0009] As a preferred embodiment of this utility model, the inner surface of the heat dissipation hole is uniformly provided with a number of heat dissipation protrusions to increase the heat dissipation area and strengthen the structural strength of the edge of the disk.

[0010] As a preferred embodiment of this utility model, the air vent is located on the outer edge of the disc body.

[0011] As a preferred embodiment of this utility model, the heat dissipation slot is formed on the surface of the disk body.

[0012] As a preferred embodiment of this utility model, the magnetic reinforcing ribs are arranged around the mounting hole.

[0013] Beneficial effects of this utility model Compared with the prior art, the present invention has the following beneficial effects: 1. Excellent heat dissipation performance: Through the multi-coordinated design of heat dissipation holes, interconnected heat dissipation grooves, heat dissipation protrusions inside the heat dissipation holes, and heat dissipation strip openings, the heat dissipation surface area of ​​the brake disc is greatly increased, forming an effective air circulation channel. This can quickly dissipate the heat generated during braking, significantly suppress brake fade, and ensure the stability of braking performance.

[0014] 2. Convenient and accurate installation: By setting up magnetic reinforcing ribs, it can automatically adhere to the iron screw holes of the wheel hub during installation, realizing the initial positioning and fixation of the disc body, solving the pain point of difficulty in drilling during installation, and greatly improving the convenience and accuracy of installation.

[0015] 3. Low wind resistance and high stability: The air vents set on the outer edge of the brake disc can effectively reduce the wind resistance faced by the brake disc when it rotates at high speed, which helps to improve the stability of the vehicle, especially during high-speed braking.

[0016] 4. High structural strength and light weight: The optimized heat dissipation protrusions not only enhance heat dissipation but also act as reinforcing ribs, improving the rigidity of the disc edge. The weight-reducing grooves, while ensuring structural strength, reasonably reduce the rotational inertia of the brake disc, achieving a balance between lightweight and high strength.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 The diagram shows a front disc brake assembly, including a disc body 1. The disc body 1 has mounting holes 21 for fixing it to the wheel hub. Multiple heat dissipation holes 4 are evenly distributed on the outer periphery of the disc body 1. Adjacent heat dissipation holes 4 are connected by heat dissipation grooves 5. A magnetic reinforcing rib 2 is provided on the disc body 1 in the area of ​​the mounting holes 21. The disc body 1 also has a weight reduction groove 3, an air vent 6, and a heat dissipation strip 7. The disc body 1 is usually forged or cast from high-strength steel to ensure its wear resistance and high temperature resistance.

[0021] In the central area of ​​the disc body 1, multiple mounting holes 21 are evenly distributed around its axis. These mounting holes 21 are used to pass bolts through, firmly fixing the disc body 1 to the hub of the motorcycle's front wheel. To greatly facilitate installation, a magnetic reinforcing rib 2 is integrally formed or fixedly embedded on the disc body 1 at the position corresponding to the mounting holes 21. The magnetic reinforcing rib 2 is preferably made of a strong permanent magnet material (such as neodymium iron boron) and is set around each mounting hole 21. During installation, the magnetism of the magnetic reinforcing rib 2 can automatically attract and initially fix the disc body 1 to the iron mounting surface of the hub, so that the mounting holes 21 of the disc body 1 are quickly and accurately aligned with the screw holes on the hub. Then, the bolts can be easily screwed in to complete the fastening, greatly improving the installation efficiency.

[0022] Multiple heat dissipation holes 4 are evenly distributed in the outer peripheral area of ​​the disk body 1. These heat dissipation holes 4 are arranged in a ring array. The key point is that adjacent heat dissipation holes 4 are interconnected by shallow groove-shaped heat dissipation channels 5. This design allows the individual heat dissipation holes 4 to be connected into a continuous mesh heat dissipation channel, which not only significantly increases the heat dissipation surface area, but also facilitates the smoother flow of air when the disk body rotates, forming a "chimney effect", thereby efficiently carrying away heat from the center of the disk body to the outer edge.

[0023] To further improve the heat dissipation effect, several inwardly protruding heat dissipation protrusions 41 are evenly arranged on the inner surface of each heat dissipation hole 4. These heat dissipation protrusions 41 further increase the inner wall area of ​​the heat dissipation hole 4, enhance local turbulence, strengthen heat exchange, and at the same time, these protrusions also act as reinforcing ribs, effectively compensating for the weakening of the outer edge strength of the disc body 1 caused by the opening, and ensuring the structural integrity of the brake disc under harsh working conditions.

[0024] To optimize the aerodynamic performance of the brake disc during high-speed rotation, multiple air-breaking openings 6 are provided at the outer edge of the disc body 1. These air-breaking openings 6 can effectively disrupt the stable air wall formed on the windward side when the brake disc rotates, and destroy the generation of vortices, thereby significantly reducing wind resistance and possible wind noise.

[0025] In addition, several weight-reducing grooves 3 and heat dissipation slots 7 are provided on the surface of the disc body 1. The weight-reducing grooves 3 are usually located in the middle of the disc body 1 where the stress is relatively small. The purpose is to reduce the weight of the brake disc as much as possible and reduce the moment of inertia while ensuring the structural strength. The heat dissipation slots 7 are long strip-shaped openings. They further increase the heat dissipation area of ​​the disc body and together with the heat dissipation holes 4 and heat dissipation grooves 5, they form a multi-layered and highly efficient heat dissipation system.

[0026] Working principle: When the motorcycle brakes, the brake caliper pushes the brake pads to clamp the rotating disc 1, generating braking force through friction. At the same time, a large amount of heat is generated. The disc 1 dissipates the heat into the air quickly through the heat dissipation holes 4, heat dissipation grooves 5, heat dissipation protrusions 41 and heat dissipation slots 7. The magnetic reinforcing ribs 2 ensure convenient and precise installation, the air vents 6 reduce wind resistance during high-speed rotation, and the weight reduction grooves 3 achieve lightweighting.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
