[0037] In order to better understand the schemes provided by the embodiments of the present application, the brake drum cracking detection device and the vehicle provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Figure 9 A structural schematic diagram of a vehicle provided by the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the vehicle 200 can at least include a vehicle body 210 and a brake drum cracking detection device 100. Figure 8 As shown in FIG. 1, the vehicle 200 can at least include a vehicle body 210 and a brake drum cracking detection device 100.

[0039] The cracking detection device 100 of the brake drum is arranged on the vehicle body 210, so that the driver or other personnel can find the cracking problem of the brake drum on the vehicle in time, and the safety and reliability of the vehicle are improved.

[0040] The vehicle provided by the application is at least composed of a vehicle body and a cracking detection device of a brake drum arranged on the vehicle body. Therefore, the driver or other personnel can find the cracking problem of the brake drum on the vehicle in time, and the safety and reliability of the vehicle are improved.

[0041] The cracking detection device of the brake drum provided by the embodiment of the application will be described in detail below with reference to the accompanying drawings. Figure 1 The structure of the cracking detection device of the brake drum provided by the embodiment of the application Figure 1 As shown in the figure, Figure 2 The cracking detection device 100 can include an electromagnetic sensor 110 and an information processor 120 arranged in the cab of the vehicle.

[0042] The probe of the electromagnetic sensor 110 is fixedly arranged at a preset position of the brake drum, and is used to collect the electric signal on the brake drum. The preset position can be selected according to the actual situation, for example, the preset position can be selected as 2mm≤preset position≤5mm.

[0043] Further, for the purpose of clearly illustrating the positional relationship between the electromagnetic sensor 110 and the brake drum, reference can be made to the following figure, Figure 1 The structure of the cracking detection device of the brake drum provided by the embodiment of the application Figure 2 As shown in the figure, Figure 3 The probe of the electromagnetic sensor 110 is fixedly arranged at a preset position of the brake drum (for example, 2mm≤preset position≤5mm), and is used to collect the electric signal on the brake drum during the driving of the vehicle.

[0044] The wiring end of the electromagnetic sensor 110 is connected to the signal input port of the information processor 120 in a wired manner, and is used to transmit the electric signal collected by the electromagnetic sensor 110 to the information processor 120, so as to be analyzed and processed. The wired connection mode between the electromagnetic sensor 110 and the information processor 120 can be selected according to the actual situation. For example, the wired connection mode can be selected as a low-voltage signal line.

[0045] The information processor 120 can be arranged at a position where it can be fixedly placed on the instrument desk or the driver's cabin of the cab of the vehicle.

[0046] In one possible implementation, since the probe of the electromagnetic sensor 110 is fixedly installed at a preset position on the brake drum, the electromagnetic sensor 110 can be used to continuously collect electrical signals on the brake drum during vehicle operation and transmit the electrical signals to the information processor 120. The information processor 120 can be used to analyze the electrical signals. If the electrical signals are continuous during vehicle operation, it indicates that the brake drum is smooth and not cracked; if the electrical signals are a clearly fluctuating signal during vehicle operation, it indicates that the brake drum has a cracking problem (such as cracks or fissures on the surface of the brake drum).

[0047] This application provides a brake drum crack detection device, which comprises an electromagnetic sensor and an information processor installed in the vehicle's cab. The probe of the electromagnetic sensor is fixedly positioned at a predetermined location on the brake drum, and the sensor's terminals are wired to the signal input port of the information processor. Therefore, by analyzing the electrical signals collected by the electromagnetic sensor and processing them through the information processor, it can be determined whether the brake drum on the vehicle has a crack problem. Compared to existing technologies, this allows for early and effective detection of brake drum cracks, preventing potential safety hazards during vehicle operation and improving vehicle safety, stability, and reliability.

[0048] The following description, in conjunction with the accompanying drawings, illustrates the brake drum crack detection device provided in the embodiments of this application. Figure 2 A schematic diagram of the structure of a brake drum crack detection device provided in this application embodiment. Figure 3 .like Figure 4 As shown, the crack detection device 100 may further include a dust cover 130 disposed on one side of the brake drum.

[0049] The probe of the electromagnetic sensor 110 extends through a preset through-hole on the dust cover 130 and is positioned at a preset location inside the brake drum (e.g., 2mm ≤ preset location ≤ 5mm). The preset through-hole can be selected according to the actual situation.

[0050] It should be noted that the dust cover 130 is stationary relative to the moving vehicle. Additionally, it should be noted that the dust cover 130 is also installed on one side of the brake drum to prevent dust or other impurities from falling into the brake drum, thereby preventing inaccurate electrical signals from the brake drum during vehicle operation.

[0051] The crack detection device of the brake drum provided by the application can also be provided at the dust cover of the preset opening of the brake drum, and is used for protecting the preset opening of the brake drum from dust or other impurities, and the probe of the electromagnetic sensor is extended to the preset position in the interior of the brake drum through the preset through hole of the dust cover, so that the electrical signal of the brake drum during driving can be effectively collected, and the brake drum is prevented from being damaged by dust and stones.

[0052] On the basis of Figure 3 , the crack detection device of the brake drum provided by the embodiment of the application is further illustrated below in combination with the accompanying drawings.

As shown in Figure 5 , the crack detection device 100 can also include a rubber plug 140.

[0053] The probe of the electromagnetic sensor 110 extends through the preset through hole of the dust cover 130 through the rubber plug 140 and is fixed with the dust cover 130. The rubber plug 140 is used for sealing protection and fixing the probe of the electromagnetic sensor 110, so as to prevent the probe from being eroded by moisture and dust.

[0054] Further, the positional relationship diagram between the rubber plug 140 and the electromagnetic sensor 110 is provided by the application, Figure 4 The structure diagram of the crack detection device of the brake drum provided by the embodiment of the application is shown in Figure 5 . As shown in Figure 6 , the probe of the electromagnetic sensor 110 can pass through the rubber plug 140.

[0055] The crack detection device of the brake drum provided by the application can also be composed of the rubber plug. The probe of the electromagnetic sensor extends through the preset through hole of the dust cover through the rubber plug and is fixed with the dust cover, so that the probe of the electromagnetic sensor can be fixed on the dust cover, is prevented from loosening due to driving of the vehicle, and is further prevented from being unable to effectively collect the electrical signal of the brake drum during driving.

[0056] Optionally, in a possible implementation, the probe of the electromagnetic sensor 110 is fixed with the dust cover 130 through interference fit of the rubber plug 140 and the preset through hole of the dust cover 130, so that the probe of the electromagnetic sensor can be fixed on the dust cover, is prevented from loosening due to driving of the vehicle, and is further prevented from being unable to effectively collect the electrical signal of the brake drum during driving.

[0057] Optionally, in a possible implementation, the probe of the electromagnetic sensor 110 extends through a preset through hole on the dust cover 130 and is fixed at a preset position of the dust cover 130 inside the brake drum, so that the probe of the electromagnetic sensor is fixed on the dust cover and is not loosened due to driving of the vehicle, thereby avoiding ineffective collection of the electric signal of the brake drum during driving.

[0058] It should be noted that in the embodiments of the present application, the preset position between the probe of the electromagnetic sensor 110 and the dust cover 130 is not limited, but it is required to ensure that the probe of the electromagnetic sensor 110 can pass through the dust cover 130 and be at a preset distance (such as 2 mm≤preset position≤5 mm) from the brake drum.

[0059] Optionally, in a possible implementation, the probe of the electromagnetic sensor 110 is fixed at a preset position (such as 2 mm≤preset position≤5 mm) inside the brake drum, so that the probe of the electromagnetic sensor can effectively collect the electric signal of the brake drum during driving of the vehicle.
