Description

Technical Field

[0001] The utility model relates to the field of braking, and more specifically, to a split brake disc. Background Art

[0002] The brake disc is installed on the shaft and cooperates with the friction plate to dissipate the kinetic energy on the shaft, brake, slow down, position and park the shaft.

[0003] The brake disc mainly transmits torque and absorbs the kinetic energy of the friction plate.

[0004] Existing brake discs are generally of an integrated structure, which is difficult to manufacture and has poor heat dissipation effect. After being worn out during use, the brake disc can only be replaced as a whole.

[0005] The present application aims to provide a split brake disc to address the defects of the existing integrated brake disc. Summary of the Invention

[0006] The utility model provides a split brake disc, which can reduce manufacturing difficulty, improve heat dissipation effect and solve the loss of the entire brake disc being scrapped after uneven wear of the brake disc.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A split brake disc includes a first plate and a second plate, the first plate and the second plate being detachably connected, the first plate having a fitting surface I, the second plate having a fitting surface II, the fitting surface I and the fitting surface II being fitted together, the fitting surface I and the fitting surface II both being provided with a plurality of protruding heat dissipation bumps, the heat dissipation bumps of the fitting surface I and the fitting surface II being arranged correspondingly, and the top surfaces of the heat dissipation bumps being fitted together to form a hollow channel, and the hollow channel being connected to the outside atmosphere.

[0009] The first and second plates have identical axial cross-sections, and their end surfaces form abutment surfaces I and II. The first and second plates combine to form the brake disc. Separate manufacturing reduces manufacturing complexity. Another purpose of the separate first and second plates is to create a hollow passageway between the first and second plates. As the brake disc rotates about its axis, airflow can pass through the hollow passageway, exchanging heat with the first and second plates, thereby reducing the temperature of the brake disc and maintaining its proper function.

[0010] The formation of the hollow channel depends on the heat dissipation bumps. The first sheet and the second sheet are in contact through the corresponding heat dissipation bumps, so that the bonding surface I and the bonding surface II are suspended in the air, and the surface area of ​​the heat dissipation bumps is relied upon to expand the heat dissipation area and improve the heat dissipation efficiency.

[0011] Preferably, a plurality of virtual closed rings centered on the disk center are provided on the bonding surface I or bonding surface II, and the virtual closed rings are expanded in a stepwise manner. Heat dissipation bumps are arranged at equal intervals on the virtual closed rings, forming a regular hexagon. The hexagonal distribution of the heat dissipation bumps can reduce air resistance and improve heat dissipation efficiency.

[0012] Preferably, the first and second plates are detachably connected via a plurality of fasteners, which are evenly spaced around the axis of the brake disc. Specifically, the fasteners include bolts and nuts. The bolts pass through the first and second plates and are threadedly connected to the nuts at their ends distal from the nuts. Equally spaced around the axis can reduce stress.

[0013] Preferably, the first sheet is detachably connected to a positioning pin, and the second sheet is provided with a positioning hole, into which the positioning pin is inserted. The positioning pin and the positioning hole can guide the connection between the first sheet and the second sheet and prevent misalignment during braking.

[0014] Preferably, the positioning pins are distributed at equal intervals around the axis of the brake disc.

[0015] Preferably, a positioning ring column is provided on the first sheet, and a positioning ring hole is provided on the second sheet, and the positioning ring column is inserted into the positioning ring hole. This structure prevents dislocation during braking.

[0016] Preferably, the positioning ring column is located on the periphery of the fastener.

[0017] Preferably, the axial cross-section of the heat dissipation protrusion is circular.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The split structure can reduce production difficulty and reduce costs;

[0020] (2) A hollow channel is formed in the middle through the heat dissipation convex point, and the air flow is formed by the rotation of the brake disc. Heat is exchanged through the air flow, which can improve the braking performance;

[0021] (3) When one side of the structure is excessively worn, the cost can be reduced by replacing it. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example:

[0034] A split brake disc, Figures 1 to 2 As shown, it comprises a first sheet 1 and a second sheet 2. The first sheet 1 and the second sheet 2 are detachably connected.

[0035] The first and second plates 1 and 2 are detachably connected by a number of fasteners, evenly spaced around the axis of the brake disc. Specifically, the fasteners include bolts 3 and nuts 4. Bolts 3 pass through the first and second plates 1 and 2, with the ends distal from the nuts threadedly connected to the nuts 4. This evenly spaced arrangement around the axis reduces stress.

[0036] The mounting nut 4 and the nut are set as countersunk holes. The screw nut 4 is made of high-strength soft material. When the brake pad is worn and contacts after the brake disc is worn, it will not damage the brake pad. The soft material can be rubber. The specific selection of soft material is common knowledge in this field. Those skilled in the art can choose and set appropriate materials according to the teachings of the present invention and actual use requirements.

[0037] In some embodiments, the fasteners are arranged in a hexagonal pattern.

[0038] The first sheet 1 is provided with a fitting surface I5, and the second sheet 2 is provided with a fitting surface II6. The fitting surface I5 and the fitting surface II6 are fitted together, and both the fitting surface I5 and the fitting surface II6 are provided with a plurality of protruding heat dissipation bumps 8.

[0039] The heat dissipation bumps 8 on the bonding surface I5 and the bonding surface II6 are correspondingly arranged and the top surfaces of the heat dissipation bumps 8 are bonded to form a hollow channel 7, which is connected to the outside atmosphere.

[0040] The mating surface I5 or II6 is provided with a plurality of virtual closed rings, each centered on the disk center, that gradually expand. Heat dissipation bumps 8 are evenly spaced within these virtual closed rings, forming a regular hexagonal shape. The hexagonal distribution of heat dissipation bumps 8 reduces air resistance and improves heat dissipation efficiency. The axial cross-section of the heat dissipation bumps 8 is circular, achieving maximum strength and support with minimal surface area, thus leaving more space for the hollow channels 7.

[0041] Ginseng Figure 3 、 4 As shown, a locating pin 9 is detachably attached to the first plate 1, and a locating hole 10 is provided in the second plate 2, into which the locating pin 9 is inserted. The locating pin 9 and the locating hole 10 provide guidance when connecting the first and second plates 1, 2, and also prevent misalignment during braking. The locating pin 9 is mounted on the first plate 1 using an interference fit. The locating pins 9 are evenly spaced around the axis of the brake disc. In some embodiments, the locating pins 9 are also arranged in a hexagonal pattern.

[0042] The first sheet 1 is provided with a positioning ring column 11, and the second sheet 2 is provided with a positioning ring hole 12, into which the positioning ring column 11 is inserted. This structure prevents misalignment during braking. The positioning ring column 11 is located on the periphery of the fastener.

[0043] The first and second plates 1 and 2 have identical axial cross-sections, and their end surfaces form abutment surfaces I5 and II6. The first and second plates 1 and 2 combine to form the brake disc. Separate manufacturing reduces manufacturing complexity. Another purpose of the separate structure of the first and second plates 1 and 2 is to create a hollow passage 7 between the first and second plates 1 and 2. As the brake disc rotates about its axis, airflow can pass through the hollow passage 7, exchanging heat with the first and second plates 1 and 2, thereby reducing the temperature of the brake disc and maintaining its proper function.

[0044] The formation of the hollow channel 7 depends on the heat dissipation bumps 8. The first sheet 1 and the second sheet 2 are in contact through the corresponding heat dissipation bumps 8, so that the bonding surface I5 and the bonding surface II6 are suspended in the air, and the surface area of ​​the heat dissipation bumps 8 is relied upon to expand the heat dissipation area and improve the heat dissipation efficiency.
