Description

Technical Field

[0001] This utility model relates to the field of motorcycle brake disc technology, and in particular to a motorcycle brake disc that is easy to replace. Background Technology

[0002] As the core component of the braking system, the technological development of motorcycle brake discs revolves around riding safety and handling stability. To adapt to the braking needs of different riding scenarios, brake discs have been continuously optimized in terms of structural design and material application, resulting in mainstream structural forms such as split-type designs. By separating the braking function from the installation function of the components, braking performance, heat dissipation performance, and structural strength are balanced. Its core technology has always focused on improving the stability of braking response and reducing safety hazards during riding, making it a key link in ensuring the reliable operation of the motorcycle braking system.

[0003] Existing motorcycle brake discs mostly use a multi-component splicing connection method, requiring the cooperation of multiple parts such as rivets, fasteners, and auxiliary shims for fixation. This results in a complex connection structure, which directly leads to a cumbersome replacement process, requiring the disassembly of multiple related components and relying on special tools, making the operation steps redundant. At the same time, under the long-term effects of braking impact and riding vibration, the complex connection structure is prone to loosening of the connecting parts, affecting braking safety. In addition, the dense layout of connecting parts and the precision assembly requirements restrict disassembly operations during routine maintenance, increasing the difficulty and time consumption of maintenance, and causing many inconveniences to users. Utility Model Content

[0004] In order to overcome the problems of existing motorcycle brake discs, which are complicated by their connection structure, making replacement cumbersome, connections prone to loosening, and maintenance and disassembly inconvenient.

[0005] The technical solution of this utility model is as follows: a replaceable motorcycle brake disc, comprising a brake disc, wherein a connecting lug is provided around the inner side of the hole of the brake disc, and the connecting lug is integrally formed with the brake disc; a connecting plate is provided at the front end of the brake disc; an embedding groove is provided around the outer side of the connecting plate; an insert is provided inside the embedding groove; a screw is provided inside the insert; a clamping plate is provided at the front end of the insert; a washer is provided at the front end of the clamping plate; and a nut is provided at the front end of the washer.

[0006] Preferably, the embedding slots are arranged at equal intervals, and the embedding slots are integrally formed with the connecting plate.

[0007] Preferably, the insert is inserted into the internal connection of the insert groove; the screw passes through the connecting ear and the hole inside the insert from back to front.

[0008] Preferably, the insert has an H-shaped cross-section.

[0009] Preferably, the screw passes through a hole in the washer; the nut and the screw are connected by a thread.

[0010] Preferably, bolt holes are provided around the central hole of the connecting plate, and the bolt holes are integrally formed with the connecting plate.

[0011] Preferably, the brake disc has heat dissipation holes on both its front and back ends, and the heat dissipation holes are integrally formed with the brake disc.

[0012] The beneficial effects of this utility model are:

[0013] 1. The design of inserting the insert into the groove of the connecting disc, with the screw passing through the connecting lug and the insert in sequence, and then fixing it with the nut and the screw thread, greatly simplifies the brake disc disassembly and assembly process. The brake disc can be replaced quickly without complicated tools, solving the problem of cumbersome replacement of traditional brake discs.

[0014] 2. Through the equidistant arrangement of the embedded slots, the H-shaped cross-section of the embedded parts, and the synergistic effect of the screw, clamping plate and gasket, the contact area and connection tightness between the components are increased, making the connection between the brake disc and the connecting disc more stable, the force is evenly distributed, and the structural loosening during braking is avoided.

[0015] 3. The integrated heat dissipation holes on both sides of the brake disc can efficiently dissipate the heat generated by braking, preventing the brake disc from deforming due to high temperature. At the same time, the gasket can prevent the nut from loosening, which significantly improves the reliability and service life of the brake disc. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] refer to Figure 1-5 The structure shown is a replaceable motorcycle brake disc, including a brake disc 101. A connecting lug 102 is provided around the inner side of the hole in the brake disc 101, and the connecting lug 102 is integrally formed with the brake disc 101. A connecting plate 201 is provided at the front end of the brake disc 101. An insert groove 203 is provided around the outer side of the connecting plate 201. An insert 302 is provided inside the insert groove 203. A screw 303 is provided inside the insert 302. A clamping piece 301 is provided at the front end of the insert 302. A washer 304 is provided at the front end of the clamping piece 301. A nut 305 is provided at the front end of the washer 304.

[0024] This utility model solves the problems of cumbersome disassembly steps, low replacement efficiency, and easy loosening of the connection structure in traditional motorcycle brake discs. Its complete workflow is as follows: First, the connecting disc 201 is fixed to the corresponding installation position of the motorcycle brake through the bolt holes 202 around the central hole; then, the insert 302 is inserted into the corresponding insertion groove 203 around the outer perimeter of the connecting disc 201; next, the screw 303 is passed from back to front through the connecting lug 102 of the brake disc 101 and the hole inside the insert 302; subsequently… Clamping plate 301 and washer 304 are sequentially fitted onto the front end of screw 303. Finally, nut 305 is tightened onto screw 303 via threads to complete the stable assembly of brake disc 101 and connecting disc 201. When brake disc 101 needs to be replaced, simply unscrew nut 305, remove washer 304 and clamping plate 301, and pull out screw 303 to remove insert 302 from insert groove 203, thereby achieving quick separation of brake disc 101 and connecting disc 201, greatly simplifying the replacement steps and improving replacement efficiency.

[0025] To address the issues of uneven stress distribution, poor connection stability, inadequate heat dissipation during braking, and easy loosening of fixing components in traditional brake disc embedding structures, reference was made to... Figures 2-5 The structure shown is as follows:

[0026] Furthermore, the embedding slots 203 are arranged at equal intervals, and the embedding slots 203 and the connecting plate 201 are integrally formed.

[0027] The design of the equidistantly spaced embedding grooves 203 allows the embedding parts 302 to be evenly distributed around the outer circumference of the connecting disc 201 after installation in the embedding grooves 203. This ensures that the force transmitted from the brake disc 101 through the connecting ears 102 is evenly distributed to various parts of the connecting disc 201. At the same time, the embedding grooves 203 and the connecting disc 201 are integrally formed, ensuring the structural strength between the embedding grooves 203 and the connecting disc 201 and preventing the embedding grooves 203 from falling off or deforming during use.

[0028] Furthermore, the insert 302 is inserted into the internal connection of the insert groove 203; the screw 303 passes through the connecting ear 102 and the hole inside the insert 302 from back to front.

[0029] The insertion of the insert 302 into the insert groove 203 enables quick positioning and installation of the insert 302 and the connecting disc 201. In addition, the screw 303 passes through the connecting ear 102 and the internal hole of the insert 302 from back to front, firmly connecting the connecting ear 102 and the insert 302 together, thus achieving a tight connection between the brake disc 101 and the connecting disc 201. At the same time, this interlocking connection structure allows for easy disassembly by simply pulling out the screw 303, which releases the fixed relationship between the brake disc 101 and the connecting disc 201.

[0030] Furthermore, the cross-section of the insert 302 is an H-shaped structure.

[0031] The H-shaped cross-section of the insert 302 allows the protruding parts on the upper and lower sides of the H-shaped structure to fit against the outer wall of the insert groove 203 and the connecting ear 102 of the brake disc 101, respectively. This increases the contact area between the insert 302 and the insert groove 203 and the connecting ear 102, which not only improves the installation stability of the insert 302 in the insert groove 203, but also effectively disperses pressure when subjected to force, avoiding excessive local stress that could lead to structural damage.

[0032] Furthermore, the screw 303 passes through the hole in the washer 304 for connection; the nut 305 is connected to the screw 303 by a thread.

[0033] The connection method of the screw 303 passing through the hole of the washer 304 allows the washer 304 to be placed between the clamping plate 301 and the nut 305, increasing the force-bearing area between the nut 305 and the clamping plate 301, and preventing the nut 305 from falling into the clamping plate 301 due to the vibration of the brake disc 101 after tightening; at the same time, the threaded connection between the nut 305 and the screw 303 enables the quick tightening and loosening of both, providing a convenient operation method for the installation and removal of the brake disc 101.

[0034] Furthermore, bolt holes 202 are provided around the central hole of the connecting plate 201, and the bolt holes 202 are integrally formed with the connecting plate 201.

[0035] The connecting disc 201 can be precisely fixed to the corresponding installation position of the motorcycle brake through the bolt holes 202 around the central hole of the connecting disc 201. The design of the bolt holes 202 and the connecting disc 201 being integrally formed ensures the structural integrity of the bolt holes 202 and the connecting disc 201, improves the stability of the connecting disc 201 after installation, and avoids the braking effect being affected by the loosening of the connecting disc 201 during braking.

[0036] Furthermore, heat dissipation holes 103 are provided on both the front and back ends of the brake disc 101, and the heat dissipation holes 103 are integrally formed with the brake disc 101.

[0037] The heat dissipation holes 103 provided on both the front and back ends of the brake disc 101 can quickly dissipate the large amount of heat generated by friction during braking, preventing the brake disc 101 from deforming or cracking due to long-term high temperature, thus extending the service life of the brake disc 101. At the same time, the heat dissipation holes 103 are integrally formed with the brake disc 101, so they will not damage the overall structural strength of the brake disc 101.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
