DETAILED DESCRIPTION
[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0029] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the relative "upper" and "lower" in the direction of gravity when the corresponding components are in use. Figures 1 to 6 The directions of the drawings shown; "inside" and "outside" refer to the "inside" and "outside" relative to the corresponding component's own contour. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.
[0030] The connecting member, the connecting assembly and the brake disc assembly in exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings.
[0031] refer to Figures 1 to 6As shown, in the first aspect of the present disclosure, there is provided a connecting member, which includes a main body 1 and an elastic member 3, wherein the main body 1 includes a mounting portion 12, the mounting portion 12 has a first stop portion 121 and a second stop portion 122 spaced apart along a first direction A, an installation space 2 for accommodating at least a portion of a first workpiece is formed between the first stop portion 121 and the second stop portion 122, an outer wall of at least one of the first stop portion 121 and the second stop portion 122 is used to abut against the second workpiece, and at least one elastic member 3 is provided on the inner wall of at least one of the first stop portion 121 and the second stop portion 122, and the elastic member 3 is used to abut against the first workpiece. The elastic member 3 on the first stopper 121 and / or the second stopper 122 can allow a certain floating area to exist in the installation space 2. The floating area is the area where the elastic member 3 can be compressed in the installation space 2 after the first workpiece is installed in the installation space 2. In this way, when the first workpiece and / or the second workpiece expands due to heat, the first workpiece and the elastic member 3 will be squeezed against each other, thereby compressing the elastic member 3. For example, when the first workpiece expands due to heat, the first workpiece is in direct contact with the elastic member 3, which will directly compress the elastic member 3, or when the second workpiece expands due to heat, the second workpiece will squeeze the first stopper 121 and / or the second stopper 122. , so that the first stop portion 121 and / or the second stop portion 122 squeeze the elastic member 3 together with the first workpiece to compress the elastic member 3; or, the first workpiece and the second workpiece are both expanded by heat, and the elastic member 3 is compressed by the direct force of the first workpiece or the indirect force of the second workpiece, thereby, the first workpiece can produce relative movement in the floating area, thereby reducing or even avoiding mechanical damage caused by mutual squeezing between the first workpiece, the second workpiece and the connecting member, based on this, it is ensured that each component can be used normally, and the safety and stability of the assembly formed by the components (such as the brake disc assembly) are improved.
[0032] In addition, it should be noted that the second workpiece can have a variety of installation positions as required, for example, Figure 6 As shown, the second workpiece can be arranged below the first workpiece, that is, the second workpiece abuts against the bottom of the second stop portion 122, or, in some embodiments not shown, the second workpiece can also be arranged above the first workpiece, that is, the second workpiece abuts against the top of the first stop portion 121, or, the second workpiece can have a lateral U-shaped groove, and at least part of the first workpiece is inserted in the U-shaped groove. At this time, after the connecting member connects the first workpiece and the second workpiece in the up and down directions, the two inner side walls of the lateral U-shaped groove in the up and down directions will respectively abut against the top of the first stop portion 121 and the bottom of the second stop portion 122, that is, the second workpiece abuts against both the first stop portion 121 and the second stop portion 122.
[0033] In some embodiments of the present disclosure, Figures 1 to 4 as well as Figure 6 As shown, a connecting piece 4 is provided at one end of the elastic member 3 away from the inner side wall of the installation space 2, and at least part of the connecting piece 4 can abut against the first workpiece. The connecting piece 4 is provided at the end of the elastic member 3, and under the action of the connecting piece 4, the connection area between the elastic member 3 and the first workpiece is increased, so that on the one hand, it can ensure that when the first workpiece and / or the second workpiece compresses the elastic member 3 due to thermal expansion, the elastic member 3 can be more stable during the compression process, and on the other hand, it can also reduce or even avoid the damage to the elastic member 3 caused by the long-term compression of the elastic member 3 by the first workpiece.
[0034] In some embodiments, Figures 1 to 4 as well as Figure 6 As shown, the body 1 further includes a rod portion 11 connected to the mounting portion 12 , the rod portion 11 extends along a first direction A to be inserted into the second workpiece, and the rod portion 11 extends the length of the connecting member to facilitate the connecting member to connect the first workpiece and the second workpiece.
[0035] Specifically, Figures 1 to 4 as well as Figure 6 As shown, in the installation space 2, the elastic member 3 can have a variety of settings, and the staff can adjust the settings of the elastic member 3 as needed. For example, one end of the elastic member 3 is connected to the first stop portion 121, and the other end is against the first workpiece. When the first workpiece and / or the second workpiece is at room temperature, that is, the first workpiece and / or the second workpiece has not expanded due to high temperature, the elastic member 3 can, under the action of its elastic force, give the first workpiece a force to move downward to ensure the stability of the first workpiece in the installation space 2. When the first workpiece and / or the second workpiece expands due to heat, the first workpiece will squeeze the elastic member 3 upward to compress the elastic member 3, so that the first workpiece can produce relative movement in the floating area. As a result, the mutual extrusion between the first workpiece, the second workpiece and the connecting member can be reduced to a certain extent, and the mechanical damage caused by mutual extrusion between the first workpiece, the second workpiece and the connecting member can be reduced or even avoided.
[0036] Alternatively, one end of the elastic member 3 can be connected to the second stop portion 122, and the other end can be against the first workpiece; when the first workpiece and / or the second workpiece are at room temperature, that is, when the first workpiece and / or the second workpiece have not expanded due to high temperature, the elastic member 3 can, under the action of its elastic force, give the first workpiece a force to move upward to ensure the stability of the first workpiece in the installation space 2, and when the first workpiece and / or the second workpiece expands due to heat, the first workpiece will squeeze the elastic member 3 downward to compress the elastic member 3 so that the first workpiece can produce relative movement within the floating area, thereby reducing the mutual extrusion between the first workpiece, the second workpiece and the connecting member to a certain extent, reducing or even avoiding the mechanical damage caused by mutual extrusion between the first workpiece, the second workpiece and the connecting member.
[0037] Alternatively, one end of at least one of the multiple elastic members 3 is connected to the first stop portion 121, and the other end is against the first workpiece; one end of at least another one is connected to the second stop portion 122, and the other end is against the first workpiece, that is, the first stop portion 121 and the second stop portion 122 are both provided with elastic members 3, and one end of the first workpiece is against the elastic member 3 provided on the first stop portion 121, and the other end is against the elastic member 3 provided on the second stop portion 122. When the first workpiece and / or the second workpiece are at room temperature, that is, when the first workpiece and / or the second workpiece are not expanded due to high temperature, the elastic member 3 located on the first stop portion 121 will give the first workpiece a force to move downward, and the elastic member 3 located on the second stop portion 122 will exert a force on the first workpiece to move downward. The elastic member 3 on the second stop portion 122 will exert a force on the first workpiece to move upward, so as to ensure the stability of the first workpiece after being connected in the installation space 2. When the first workpiece and / or the second workpiece expands due to heat, the elastic member 3 on the first stop portion 121 will move upward under the extrusion of the first workpiece, and the elastic member 3 on the second stop portion 122 will move downward under the extrusion on the first workpiece, so that the first workpiece will produce relative movement in the floating area, which can reduce the mutual extrusion between the first workpiece, the second workpiece and the connecting member to a certain extent, and reduce or even avoid the mechanical damage caused by mutual extrusion between the first workpiece, the second workpiece and the connecting member.
[0038] In some embodiments of the present disclosure, Figures 1 to 4 as well as Figure 6 As shown, the mounting portion 12 has a plurality of first stoppers 121 and second stoppers 122, and the plurality of first stoppers 121 and second stoppers 122 are arranged at intervals along the circumferential direction to form a plurality of mounting spaces 2. Increasing the number of mounting spaces 2 can ensure the stability of the first workpiece and the second workpiece after connection, while minimizing the mechanical damage caused by mutual extrusion between the first workpiece, the second workpiece and the connecting member.
[0039] In some embodiments, Figures 1 to 4 as well as Figure 6 As shown, the elastic member 3 can be configured as a spring 31. The spring 31 is not easy to age and has a certain temperature resistance. Using the spring 31 as the elastic member 3 can increase the service life of the elastic member 3.
[0040] Among them, Figures 1 to 4 as well as Figure 6As shown, the number of supporting circles of the spring 31 can be 1.5-2.5 circles, which can ensure the strength and stiffness of the spring 31 when it is connected to the first stop portion 121 or the second stop portion 122, ensure the stability of the elastic member 3 after being connected to the stop portion, and reduce the wear on the elastic member 3 caused by the mutual extrusion between the first workpiece, the second workpiece and the connecting member, thereby increasing the service life of the spring 31.
[0041] In addition, if Figures 1 to 4 as well as Figure 6 As shown, the effective number of turns of the spring 31 is configured to be at least 2 turns, which can make the spring 31 have higher stability during compression and extension and help the spring 31 to distribute stress more evenly when subjected to force, thereby reducing local fatigue damage caused by stress concentration.
[0042] In addition, if Figures 1 to 4 as well as Figure 6 As shown, the free length of the spring 31 is greater than or equal to 0.65 mm, and the length of the spring 31 in the installed state when the connecting member is installed on the first workpiece is greater than or equal to 0.5 mm, so as to ensure that there is a certain gap between the components to prevent mechanical damage between the components due to excessive extrusion.
[0043] In the second aspect of the present disclosure, Figure 4 and Figure 6 As shown, a connection assembly is provided, including a first fastener 5, a second fastener 8 and the above-mentioned connection member, the connection member is provided with a through hole 9, and the first fastener 5 is connected to the second fastener 8 through the through hole 9. Specifically, the first fastener 5 can be configured as a bolt, the second fastener 8 can be a fastening nut, the connection member can be a sleeve, the through hole 9 can penetrate the mounting portion 12 and the rod portion 11 of the sleeve, the bolt passes through the mounting portion 12 and the rod portion 11 in sequence through the through hole 9 so that the sleeve is sleeved on the outside of the bolt, and at the same time, the bolt also passes through the connection structure (such as a connection hole or a connection groove structure) on the first workpiece and the second workpiece, and connects the first workpiece and the second workpiece through the fastening nut. In this process, part of the first workpiece is located in the installation space 2 of the mounting portion 12 of the sleeve, so that when the first workpiece and / or the second workpiece expands due to heat, the first workpiece can generate relative movement in the floating area to reduce the extrusion between the components.
[0044] The third aspect of the present disclosure is as follows Figure 5As shown, a brake disc assembly is provided, comprising a central connecting disc 6, a brake disc 7 and the above-mentioned connecting assembly, wherein the central connecting disc 6 is a first workpiece, the brake disc 7 is a second workpiece, and the brake disc 7 is connected to the central connecting disc 6 through a plurality of connecting assemblies. The brake disc 7 will heat up and expand under continuous braking to squeeze the surrounding components, specifically, the brake disc 7 abuts against the outer wall of the second stopper 122, and after the brake disc 7 heats up and expands, it squeezes the outer wall of the second stopper 122, thereby compressing the elastic member 3, and the central connecting disc 6 located in the installation space 2 generates relative movement in the floating area, thereby reducing the squeezing of other surrounding components, thereby reducing or even avoiding the mechanical damage caused by mutual squeezing between the components.
[0045] A fourth aspect of the present disclosure provides a vehicle, comprising the above brake disc assembly. In addition, the vehicle has all the beneficial effects of the above brake disc assembly, which will not be described in detail in the present disclosure.
[0046] In summary, the present disclosure exemplarily illustrates the working principles of a connector, a connector assembly, and a brake disc assembly.
[0047] The brake disc 7 and the center connecting disc 6 of the brake disc assembly are provided with connecting structures correspondingly, wherein the outer peripheral side of the center connecting disc 6 may be provided with a connecting groove extending toward the central area of the center connecting disc 6, and the brake disc 7 may be provided with a connecting hole corresponding to the connecting groove. When the center connecting disc 6 and the brake disc 7 are connected, part of the mounting portion 12 of the connecting member of the connecting assembly is located in the connecting groove, and the first stop portion 121 and the second stop portion 122 are located outside the connecting groove, so that at least one of the upper and lower end surfaces of the center connecting disc 6 is against the spring 31 in the installation space 2, and the rod portion 11 of the connecting member is inserted into the connecting hole of the brake disc 7, and the bolt can pass through the through holes 9 on the mounting portion 12 and the rod portion 11 through the center connecting disc 6 and the brake disc 7, and use a fastening nut The brake disc 7 and the center connecting disc 6 are connected. At this time, part of the center connecting disc 6 is located in the installation space 2 of the sleeve sleeved outside the bolt. When the brake disc 7 expands due to heat, the second stop portion 122 will be squeezed, so that the spring 31 located in the installation space 2 is compressed under the squeezing of the first stop portion 121, the second stop portion 122 and the center connecting disc 6, so that the center connecting disc 6 can produce relative movement in the floating area, thereby reducing the squeezing of the brake disc 7 on the connecting assembly and / or the center connecting disc 6. Therefore, the present disclosure can reduce or even avoid the situation where the brake disc 7, the center connecting disc 6 and the connecting assembly are mechanically damaged due to mutual squeezing. Based on this, it is ensured that each component can be used normally, and the safety and stability of the brake disc assembly are improved.
