Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing equipment, and in particular to a brake corrosion resistance testing device. Background Technology

[0002] Automotive brakes are critical components related to driving safety, and their performance stability and reliability are of paramount importance. Since brakes are constantly exposed to the vehicle's exterior, they are subjected to corrosion from harsh environments such as rain, mud, and winter de-icing agents; therefore, their corrosion resistance is an important indicator of their quality.

[0003] Currently, corrosion resistance testing of brake components such as brake discs and calipers is generally conducted using traditional salt spray chambers. However, traditional salt spray chambers can only provide a constant temperature and humidity environment, which is far removed from the complex cyclical conditions of "humidity-dryness-high and low temperature alternation" experienced by vehicles in the real world. Furthermore, existing testing methods are mostly static tests and cannot simulate the micro-movements of components, ventilation, and the dynamic adhesion and erosion processes of corrosive media during vehicle operation. After testing, the samples must be removed for functional evaluation, a cumbersome and inefficient process. Therefore, this application provides a brake corrosion resistance testing device to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a brake corrosion resistance testing device, which aims to solve the problems of the existing technology's single corrosion testing environment and inability to truly simulate complex working conditions such as alternating wet and dry conditions of vehicles.

[0005] To achieve the above objectives, this application provides the following technical solution: a brake corrosion resistance testing device, comprising a base and a shield; The base is equipped with a mounting plate and a soaking water tank; The mounting plate is provided with a rotating mechanism for mounting brake components; The soaking water tank is located below the rotating mechanism; The shield is positioned above the rotating mechanism, and the shield is equipped with a spray pipe; It also includes a circulating water pipe system that connects a liquid source to the spray pipe, thereby enabling the integration of multiple corrosion modes and more realistically simulating actual working conditions.

[0006] Preferably, the rotating mechanism is replaceably equipped with a flange for fixing the brake disc component, which improves the adaptability and versatility of the device for brake components of different specifications.

[0007] Preferably, the mounting plate is replaceably provided with a fixing plate for mounting the brake pad assembly. The fixing plate is located near the rotating mechanism, thereby enabling collaborative corrosion testing under combined working conditions and making the test scenario more realistic.

[0008] Preferably, the rotating mechanism further includes a drive shaft, one end of which passes through a through hole in the mounting plate and is connected to the flange, and the other end of which is connected to a drive wheel. The mounting plate is provided with a support platform, and the support platform is provided with a bearing seat for rotatably supporting the drive shaft, thereby ensuring the stability and reliability of the rotating mechanism.

[0009] Preferably, the base is further provided with a camera, the lens of which faces the installation area of ​​the rotating mechanism, so as to facilitate continuous dynamic recording and analysis of the corrosion process.

[0010] Preferably, the liquid source is a circulating water tank, which is mounted on the base; the circulating water pipe system includes a water pump, which pumps the liquid in the circulating water tank to the spray pipe, ensuring the independence and stability of the spray system medium.

[0011] Preferably, the shield is also provided with an air duct for forced drying and a sensor module for monitoring the internal environmental parameters of the shield, making it possible to conduct wet-dry alternating cycle tests and precise environmental control, which greatly improves the scientific nature of the test.

[0012] In summary, the technical effects and advantages of this utility model are as follows: This invention integrates immersion, spraying, rotation, and forced drying functions into one unit, and uses a sensor module for environmental monitoring. It can simulate the alternating process of components being immersed, rinsed, and dried by salt water during operation, which is closer to real corrosion conditions than traditional static salt spray testing.

[0013] In this invention, by using replaceable flanges and fixing plates, one set of equipment can be adapted to brake discs and brake pad assemblies of different specifications, realizing the coordinated testing of individual components or combinations of components, and has a wide range of applications.

[0014] In this invention, the mechanical structure is designed to be stable and reliable. Through an independent camera and sensor module, the corrosion process and environmental parameters can be continuously and dynamically recorded, which facilitates the analysis of corrosion mechanism and the evaluation of product performance.

Example

[0019] refer to Figure 1-5The device shown comprises a base 1 and a mounting plate 2 vertically fixed thereon. The base 1 provides a stable foundation for the entire device, and an immersion tank 4 for holding corrosive liquid is installed on it. The immersion tank 4 is located at the front of the device, providing the necessary conditions for subsequent immersion corrosion testing. This device integrates rotary drive, immersion corrosion, spray corrosion, forced drying, and real-time monitoring functions to provide a comprehensive corrosion testing platform for brake components. By combining multiple corrosion modes with dynamic simulation, this solution aims to solve the shortcomings of existing technologies, such as the single corrosion testing environment and the inability to realistically simulate complex working conditions such as alternating wet and dry conditions of vehicles. This provides a more realistic and reliable comprehensive corrosion testing platform for brake components.

[0020] As one implementation method in this embodiment, the rotating mechanism 3 is the core of realizing dynamic testing. The precision mechanical structure of the rotating mechanism 3 includes a drive shaft that passes through a through hole opened on the mounting plate 2. The drive shaft is rotatably supported by a bearing seat set on the support platform 33, ensuring the smoothness of rotation. The front end of the drive shaft is connected to a flange 31, and the rear end is connected to a drive wheel 32 for receiving external power. To improve the versatility of the device, the flange 31 is designed as a replaceable structure to adapt to brake disc components of different specifications.

[0021] As one implementation method in this embodiment, in order to simulate the actual working conditions of the brake assembly, the device is also provided with a replaceable fixing plate 21 on the mounting plate 2. The fixing plate 21 is located near the flange 31. Its design purpose is to install the brake pad component assembly, thereby enabling collaborative corrosion testing of the brake disc and brake pad in combination, making the test scenario more realistic.

[0022] As one implementation method in this embodiment, the shield 5 creates a controllable microenvironment for the device. The shield 5 is placed above the rotating mechanism 3 and the immersion tank 4. For easy real-time observation, the shield 5 is made of a transparent and corrosion-resistant material such as acrylic sheet. To achieve advanced cyclic corrosion testing, the shield 5 integrates multiple functional units: a spray pipe 62 for spraying is fixed on its top inner wall; an air duct 51 for connecting an external fan to achieve forced drying is opened on its wall; and a sensor module for monitoring the internal environment, such as temperature and humidity sensors, is also installed on its inner wall.

[0023] As one implementation method in this embodiment, the circulating water pipe 6 system is the guarantee for realizing the spraying function. The system includes a circulating water tank 41 independently set on the base 1, a water pump 63 and a conduit 61 connecting the two. The system pumps the liquid in the circulating water tank 41 to the spray pipe 62 in the shield 5 through the water pump 63 and the conduit 61 to spray the rotating sample evenly.

[0024] As one embodiment of this invention, the device also includes a camera 7 mounted on the base 1, with its lens precisely aimed at the sample mounting area, for unattended dynamic video recording of the entire testing process, providing intuitive data for subsequent corrosion analysis.

[0025] The working principle of this device is as follows: First, the brake disc and brake pad assembly to be tested are installed on the device using the replaceable flange 31 and fixing plate 21; then, a cyclical test program including steps such as immersion, spraying, and drying is set through an external controller. After the program is started, the rotating mechanism 3 drives the brake disc to rotate at a low speed, and the controller can instruct the device to execute the following: During the soaking stage, the lower half of the rotating brake disc is periodically immersed in the liquid in the soaking tank 4. During the spraying stage, the water pump 63 is started, and the sample is sprayed through the spray pipe 62; During the drying stage, the liquid supply is stopped, and air is blown in through the air duct 51 for forced drying. Throughout the entire cycle, sensor module 52 monitors the environmental parameters inside the enclosure in real time and feeds them back to the controller to form a closed-loop control, while camera 7 records the entire process. Through multiple cycles, the harsh corrosive environment experienced by the brake on a real road can be highly reproduced.
