The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0046] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0047] In a vehicle's braking system, friction between the brake disc and brake pads often triggers Metallic Pick-Up (MPU), affecting the brake disc's appearance. Therefore, after the brake disc is manufactured, it is typically inspected for MPU to assess its appearance quality. However, existing inspection methods primarily focus on independently testing the brake disc and brake pads, lacking consideration of actual factors affecting the brake disc during actual operation after assembly, resulting in lower accuracy and reliability of the inspection results.

[0048] The present invention discloses a method for testing a brake disc, which can be applied to a testing mechanism for performing braking operations on the brake disc. Specifically, the testing mechanism may include an inertia testing bench, which may include a mounting base, a brake caliper, and friction pads. The mounting base is used to mount the brake disc, the friction pads are spaced apart from the brake disc, and the brake caliper can drive the brake disc to move toward and contact the brake disc, thereby realizing the braking operation on the brake disc.

[0049] Reference Figure 1 As shown, in this embodiment of the invention, the detection method may include:

[0050] Step S101: Obtain first operation information based on preset reference information.

[0051] It should be noted that, in this embodiment of the invention, the preset reference information may include, but is not limited to, data such as: initial braking speed, final braking speed, friction pad temperature, ambient temperature, and number of braking operations. The preset reference information serves as a reference standard for operating condition data, which can be derived by operators based on the basic parameters of the brake disc, or it can be compiled from data obtained by sensors installed on the vehicle after road testing of the brake disc. This embodiment does not limit this. It is understood that the preset reference information can serve as a reference standard for the first operating information; therefore, the first operating information can be selected by operators based on the preset reference information. For example, the preset reference information may be: initial braking speed 60 km / h, final braking speed 10 km / h, friction pad temperature 80°C, and number of braking operations 180. The first operating information can be operating condition data that is more stringent than the preset reference information, such as: initial braking speed 80 km / h, final braking speed 0 km / h, friction pad temperature 100°C, and number of braking operations 200. The first operating information provides the brake disc with operating conditions that are more stringent than actual operating conditions, thereby simulating various real-world factors that arise during actual operation after the brake disc is installed in the vehicle.

[0052] Step S102: Control the detection mechanism to perform the first braking operation on the brake disc according to the first operation information.

[0053] In this embodiment of the invention, the detection mechanism can perform a first braking operation on the brake disc according to the first operation information, so that the brake disc runs for a certain period of time under simulated actual working conditions, thereby realizing the break-in of the brake disc.

[0054] Step S103: Obtain second operation information based on preset reference information and first operation information.

[0055] Understandably, the second operational information can be the operating conditions of the brake disc under harsh conditions. The preset reference information and the first operational information can serve as a common reference standard for the second operational information. Therefore, the second operational information can be selected by the operator based on the preset reference information and the first operational information. For example, the preset reference information might be: initial braking speed 60 km / h, final braking speed 10 km / h, friction pad temperature 80℃, and 180 braking operations. The first operational information might be: initial braking speed 80 km / h, final braking speed 0 km / h, friction pad temperature 100℃, and 200 braking operations. The second operational information could be even more stringent operating conditions than the first two, such as: initial braking speed 100 km / h, final braking speed 0 km / h, friction pad temperature 200℃, and 250 braking operations.

[0056] Step S104: Control the detection mechanism to perform a second braking operation on the brake disc according to the second operation information.

[0057] In this embodiment of the invention, the testing mechanism can perform a second braking operation on the brake disc according to the second operation information, thereby causing the brake disc to operate for a period of time under the working conditions provided by the second operation information. It is understood that the quality performance exhibited by the brake disc after operating under the working conditions provided by the second operation information can serve as an expectation of the operator regarding factors such as the strength, performance, and durability of the brake disc.

[0058] Step S105: Determine the surface features of the brake disc after the second braking operation to assess the quality of the brake disc.

[0059] In this embodiment of the invention, the surface features of the brake disc can be used as a manifestation of its MPU phenomenon. Specifically, the surface features of the brake disc can include scratches. Operators can confirm the surface features of the brake disc by observing them or by visually identifying them using equipment, thereby enabling quality assessment of the brake disc.

[0060] The detection mechanism disclosed in this invention is used to perform braking operations on a brake disc. The detection method involves: acquiring first operation information based on preset reference information; controlling the detection mechanism to perform a first braking operation on the brake disc based on the first operation information; acquiring second operation information based on the preset reference information and the first operation information; controlling the detection mechanism to perform a second braking operation on the brake disc based on the second operation information; determining the surface characteristics of the brake disc after the second braking operation to assess the quality of the brake disc; achieving brake disc break-in through the first braking operation, placing the brake disc under the same operating conditions as when it is installed on the vehicle, making the brake disc more closely resemble the actual operating conditions, thus solving the technical problem of lacking consideration of actual factors generated during the actual operation of the brake disc after it is assembled into the vehicle; and then, by determining the surface characteristics of the brake disc after performing the second braking operation, the detection of the brake disc MPU phenomenon is achieved, thereby enabling quality assessment of the brake disc, greatly improving the accuracy and authenticity of brake disc detection.

[0061] The present invention discloses a method for detecting a brake disc, which can be applied to a detection mechanism for performing braking operations on the brake disc. The detection mechanism may include a first sensor and a first temperature control unit. The first sensor can be used to detect the ambient temperature, and the first temperature control unit can be used to control the ambient temperature. The first operation information may include a first initial velocity, a first final velocity, and a first deceleration. The second operation information may include a second initial velocity, a second final velocity, and a second deceleration. The detection mechanism may include a brake caliper and a friction pad. The brake caliper can be used to drive the friction pad to move and contact the brake disc to brake the brake disc. The detection mechanism may also include a second sensor and a second temperature control unit. The second sensor can be used to detect the temperature of the friction pad, and the second temperature control unit can be used to control the temperature of the friction pad.

[0062] Reference Figure 2 As shown, in this embodiment of the invention, the detection method may include:

[0063] Step S201: Obtain first operation information based on preset reference information.

[0064] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0065] Step S202: Control the second temperature control unit to heat the current temperature of the first friction plate to the second target temperature value.

[0066] In this embodiment of the invention, before performing the first braking operation, the second temperature control unit can heat the current temperature of the friction pad to a second target temperature value, so that the friction pad is at the required operating temperature before performing the first braking operation. It should be noted that the second target temperature value can be selected and set by the operator according to the actual situation; this embodiment does not limit this setting.

[0067] Step S203: Control the detection mechanism to brake the brake disc so that the brake disc brakes from the first initial velocity to the first final velocity with a first deceleration.

[0068] In this embodiment of the invention, the detection mechanism can perform a first braking operation on the brake disc. Specifically, the brake disc can be braked from a first initial velocity to a first final velocity with a first deceleration. In this embodiment, the first initial velocity can be the vehicle's speed when the driver is driving at a constant speed, the first deceleration can be the vehicle's deceleration when the driver is braking normally, and the first final velocity can be the vehicle's speed when driving at a low speed, or it can be the speed corresponding to the vehicle coming to a stop, which is 0.

[0069] Step S204: Obtain second operation information based on preset reference information and first operation information.

[0070] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0071] Step S205: Control the second temperature control unit to heat the current temperature of the second friction plate to the third target temperature value.

[0072] In this embodiment of the invention, before performing the second braking operation, the second temperature control unit can heat the current temperature of the friction pad to a third target temperature value, so that the friction pad is at the required operating temperature for the second braking operation. It should be noted that the third target temperature value can be selected and set by the operator according to the actual situation; this embodiment does not limit this setting.

[0073] Step S206: Control the first temperature control unit to heat the current ambient temperature to the first target temperature value.

[0074] In this embodiment of the invention, before performing the second braking operation, the current ambient temperature can be heated to a first target temperature value by the first temperature control unit, so that the brake disc is at the required operating temperature before performing the second braking operation. It should be noted that the first target temperature value can be selected and set by the operator according to the actual situation; this embodiment does not limit this setting.

[0075] Step S207: Control the detection mechanism to brake the brake disc so that the brake disc brakes from the second initial velocity to the second final velocity with the second deceleration.

[0076] In this embodiment of the invention, the detection mechanism can perform a second braking operation on the brake disc. Specifically, the brake disc can be braked from a second initial velocity to a second final velocity with a second deceleration. In this embodiment, the second initial velocity can be the vehicle's speed when the driver is driving at a high speed, the second deceleration can be the vehicle's deceleration when the driver brakes suddenly, and the first final velocity can be the vehicle's speed when traveling at a low speed, or it can be the speed corresponding to the vehicle coming to a stop, which is 0. It is understood that the second braking operation can be a more intense braking action than the first braking operation; therefore, the second initial velocity can be higher than the first initial velocity, and the second deceleration can be greater than the first deceleration.

[0077] Step S208: Determine the surface features of the brake disc after the second braking operation to assess the quality of the brake disc.

[0078] In this embodiment of the invention, surface features may include, but are not limited to, scratch depth and scratch number. Operators can assess the MPU phenomenon of the brake disc based on the scratch depth and scratch number on the surface of the brake disc after the second braking operation, and then conduct a quality assessment of the brake disc.

[0079] In this embodiment of the invention, the step S208 may further include:

[0080] Step S209: Obtain third operation information based on preset reference information, first operation information, and second operation information.

[0081] Understandably, the third operational information can be the operating conditions of the brake disc under extreme conditions. The preset reference information, the first operational information, and the second operational information can serve as a common reference standard for the third operational information. Therefore, the third operational information can be selected by the operator based on the preset reference information, the first operational information, and the second operational information. For example, the preset reference information might be: initial braking speed 60 km / h, final braking speed 10 km / h, friction pad temperature 80℃, and 180 braking operations. The first operational information might be: initial braking speed 80 km / h, final braking speed 0 km / h, friction pad temperature 100℃, and 200 braking operations. The second operational information might be: initial braking speed 100 km / h, final braking speed 0 km / h, friction pad temperature 200℃, and 250 braking operations. The third operational information can then be more stringent operating conditions than the preset reference information, the first operational information, and the second operational information, such as: initial braking speed 120 km / h, final braking speed 0 km / h, friction pad temperature 2500℃, and 280 braking operations.

[0082] Step S210: Control the detection mechanism to perform a third braking operation on the brake disc according to the third operation information.

[0083] In this embodiment of the invention, the testing mechanism can perform a third braking operation on the brake disc according to the third operating information, thereby causing the brake disc to operate for a period of time under the working conditions provided by the third operating information. It is understood that the quality performance exhibited by the brake disc after operating under the working conditions provided by the third operating information can serve as an expectation of the operator regarding factors such as the strength, performance, and durability of the brake disc.
