[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] An embodiment of the present application provides a brake hose durability testing device.

[0024] In one embodiment, referring to Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the brake hose durability test device of this application. Figure 1 As shown, the brake hose durability testing device includes: a body 1, a rotating platform 2, a functional module 3 and a driving mechanism 4.

[0025] The main body 1 is provided with a guide rail 11 ; the rotating platform 2 is arranged on the guide rail 11 ; and the rotating platform 2 is further provided with a second pressure interface 21 .

[0026] The functional module 3 includes at least one functional unit, which includes a corresponding first replacement module 31 and a second replacement module 32. The first replacement module 31 is detachably arranged on the main body 1, and the first replacement module 31 is also provided with a first pressure interface 311 and a first brake hose interface 312. The second replacement module 32 is detachably arranged on the rotating table 2 and can be flipped on the rotating table 2, and the second replacement module 32 is also provided with a second brake hose interface 321.

[0027] The driving mechanism 4 is disposed on the main body 1 , and is connected to the rotating platform 2 , and is used to drive the rotating platform 2 to reciprocate along the guide rail 11 .

[0028] It should be noted that the first pressure port 311 and the second pressure port 21 are used to connect to a pressure device, which provides air pressure or hydraulic power to drive the corresponding components. When a brake hose is connected between the first brake hose port 312 and the second brake hose port 321, air pressure or hydraulic power provided by the first pressure port 311 can be used to rotate the second replacement module 32, while air pressure or hydraulic power provided by the second pressure port 21 can be used to rotate the turntable 2.

[0029] Specifically, based on the plane where the guide rail 11 is located, an XYZ coordinate system is established with the longitudinal direction of the guide rail 11 as the X-axis, the direction perpendicular to the X-axis as the Y-axis, and the direction perpendicular to the plane as the Z-axis. The rotating table 2 can then rotate about the Z-axis, and the second replacement module 32 can flip about the Y-axis.

[0030] That is to say, the guide rail 11 and the driving mechanism 4 can be used to test the brake hose under linear reciprocating conditions, the rotation of the turntable 2 itself can be used to test the brake hose under rotation conditions, and the flipping of the second replacement module 32 on the turntable 2 can be used to test the brake hose under flipping conditions, thereby providing endurance motion under multiple conditions in a simulated test on one test device.

[0031] Furthermore, since the first and second replacement modules 31 and 32 can be replaced according to actual needs, for example, modules with different brake hose interface diameters can be replaced to test brake hoses of different sizes. Different types of brake hose interfaces can also be replaced to accommodate hydraulic brake hoses, pneumatic rubber brake hoses, vacuum brake hoses, or pneumatic plastic brake hoses. This allows for different test scenarios by installing different functional modules, reducing the use of fixtures, shortening auxiliary work hours, and improving test efficiency.

[0032] For specific implementation, see Figure 2 and Figure 3 As shown, the rotating platform 2 includes a base 22 , a turntable 23 and a connecting assembly 24 .

[0033] Among them, the base 22 is arranged on the guide rail 11, and the second pressure interface 21 is provided on the base 22; the turntable 23 is rotatably connected to the base 22; the connecting component 24 is fixed on the turntable 23 and is detachably connected to the second replacement module 32.

[0034] Furthermore, the connecting assembly 24 includes a first connecting member 241 and a second connecting member 242 .

[0035] The first connecting member 241 is connected to the turntable 23, and a dovetail structure is provided on the first connecting member 241; the second connecting member 242 is connected to the second replacement module 32, and a dovetail groove adapted to the dovetail structure is provided on the second connecting member 242.

[0036] That is to say, in this embodiment, the detachable connection between the second replacement module 32 and the rotating platform 2 is achieved by cooperating with the dovetail tenon and the dovetail groove. Figure 4 As shown, during use, the dovetail groove is slidably clamped onto the dovetail tenon structure, and then the second replacement module 32 is fixed to the second connecting member 242 via bolts 244. In addition, to prevent the first connecting member 241 and the second connecting member 242 from moving relative to each other, the connecting assembly 24 also includes a first locking pin 243. The first locking pin 243 is inserted into the second connecting member 242 and is used to lock the second connecting member 242 to the first connecting member 241. Specifically, in this embodiment, the lower portion of the second connecting member 242 has a reserved hole. When the dovetail tenon structure and the dovetail groove are tightly fitted, the first locking pin 243 can be inserted into the reserved hole, at which point the dovetail mating portion is locked.

[0037] At the same time, the main body 1 is also provided with a mounting base 12, which is located at one end of the guide rail 11 and is detachably connected to the first replacement module 31. Similar to the connecting component 24 described above, the mounting base 12 is also provided with a dovetail structure, and the first replacement module 31 is provided with a dovetail groove that is compatible with the dovetail structure. Therefore, by replacing the first replacement module 31 and cooperating with the second replacement module 32, switching between hydraulic pressure testing, air pressure testing, and negative pressure testing can be achieved. Preferably, the mounting base 12 is also provided with a second locking pin 13, which can be used to lock the first replacement module 31 and the mounting base 12.

[0038] Furthermore, a pressure gauge 313 is provided on the first replacement module 31. The pressure gauge 313 can monitor the pressure change during the test in real time.

[0039] It is worth noting that conventional endurance dynamic ozone test benches, due to the use of a connecting rod mechanism, are subject to sudden acceleration and deceleration, resulting in significant fluctuations in the test state of the test piece. Therefore, the drive mechanism 4 in this embodiment uses a servo motor to effectively avoid sudden acceleration and deceleration during the test.

[0040] To sum up, the brake hose durability test device in the present application includes a main body 1, which is provided with a guide rail 11; a rotating table 2, which is arranged on the guide rail 11, and the rotating table 2 is also provided with a second pressure interface 21; a functional module 3, which includes at least one functional unit, the functional unit includes a first replacement module 31 and a second replacement module 32 that are adapted, the first replacement module 31 is detachably arranged on the main body 1, and the first replacement module 31 is also provided with a first pressure interface 311 and a first brake hose interface 312, the second replacement module 32 is detachably arranged on the rotating table 2 and can be flipped on the rotating table 2, and the second replacement module 32 is also provided with a second brake hose interface 321; a driving mechanism 4, which is arranged on the main body 1, the driving mechanism 4 is connected to the rotating table 2, and is used to drive the rotating table 2 to move back and forth along the guide rail 11.

[0041] This application enables testing of the brake hose under linear reciprocating conditions through the guide rail 11 and drive mechanism 4, testing under rotational conditions through the rotation of the turntable 2 itself, and testing under reversal conditions through the flipping of the second replacement module 32 on the turntable 2. This allows for endurance testing under multiple conditions in simulated tests using a single test device. Furthermore, since the first replacement module 31 and the second replacement module 32 can be replaced as needed, different test contents can be implemented by installing different functional modules, reducing the use of fixtures, shortening auxiliary work hours, and improving test efficiency.
