[0027] Combination Figure 1-4 As shown, an embodiment of the present disclosure provides a universal brake assembly 6 drag torque detection device, including a base 1, a fixed plate 2, a first adapter plate 3, a synchronization mechanism 4 and a driving member 5, wherein the fixed plate 2 is arranged on the base 1, the fixed plate 2 includes a main body 21 and a fixing portion 22, the fixing portion 22 is movably connected to the main body 21, the brake assembly 6 is fixed between the main body 21 and the fixing portion 22, the first adapter plate 3 is arranged on a side of the brake assembly 6 away from the fixed plate 2, and is connected to the brake assembly 6, the driving member 5 is arranged on the base 1, one end of the synchronization mechanism 4 is connected to the driving member 5, and the other end is connected to the first adapter plate 3.

[0028] The universal brake assembly 6 drag torque detection device provided by the embodiment of the present disclosure is adopted. The brake assembly 6 is fixed to the fixed plate 2, and the fixed portion 22 of the fixed plate 2 is movably connected to the main body 21. When the fixed portion 22 fixes the brake assembly 6, the position of the fixed portion 22 relative to the main body 21 can be adjusted according to the corresponding dimensions of different types of brake assemblies 6, so as to realize the fixation of different types of brake assemblies 6, thereby improving the versatility of the detection device. The first adapter plate 3 is arranged between the brake assembly 6 and the synchronization mechanism 4, so as to realize the connection between different types of brake assemblies 6 and the synchronization mechanism 4, thereby improving the versatility of the detection device of the present application to a certain extent.

[0029] Based on the above technical solution, Figure 1 and Figure 2 As shown, the fixing plate 2 also includes a fixing fitting portion 23 , which is connected to the main body 21 and arranged opposite to the fixing portion 22 . The brake assembly 6 includes a steering knuckle 61 , which is fixed between the fixing portion 22 and the fixing fitting portion 23 .

[0030] The fixed fitting portion 23 is arranged opposite to the fixed portion 22, and the fixed portion 22 is movably connected to the main body 21, so that the steering knuckle 61 of the brake assembly 6 is fixed between the fixed portion 22 and the fixed fitting portion 23. By adjusting the position of the fixed portion 22 relative to the main body 21, the distance between the fixed portion 22 and the fixed fitting portion 23 is adjusted to adapt to different sizes corresponding to steering knuckles 61 of different structures, so as to realize the fixation of steering knuckles 61 of different models, thereby realizing the fixation of the brake assembly 6.

[0031] Specifically, the fixing portion 22 is provided with a first through hole, the fixing matching portion 23 is provided with a second through hole, and the steering knuckle 61 is provided with a third through hole. The detection device also includes a fixing bolt and a nut. The fixing bolt passes through the first through hole, the third through hole and the second through hole in sequence, and the nut is sleeved on one end of the fixing bolt to achieve the fixation of the steering knuckle 61.

[0032] Based on the above technical solution, Figure 2 As shown, the main body 21 is provided with a first slot 211 , and the first slot 211 extends in a horizontal direction. The fixing portion 22 is provided in the first slot 211 and can slide in the first slot 211 relative to the main body 21 .

[0033] The fixing portion 22 slides in the first slot 211 to adjust its position relative to the main body 21 , so as to adjust the distance between the fixing portion 23 and the fixing portion 23 , thereby fixing the steering knuckle 61 .

[0034] Specifically, Figure 2 As shown, the first slot 211 extends horizontally along the width direction of the fixing plate 2, and penetrates the fixing plate 2 along the thickness of the fixing plate 2. The fixing portion 22 is provided with an extension structure 221, and the extension structure 221 is inserted into the first slot 211. The main body 21 is also provided with a sub-slot 213. The sub-slot 213 is provided on the top wall of the main body 21, extends along the width direction of the main body 21, and extends toward the direction of the first slot 211, and is connected to the first slot 211. The detection device also includes a small bolt 214, which is inserted into the sub-slot 213, and the end of the small bolt 214 abuts against the extension structure 221 to fix the fixing portion 22 to the main body 21. The small bolt 214 can move along the sub-slot 213 to follow the fixing portion 22 to slide along the first slot 211, thereby achieving the fixing effect of the fixing portion 22.

[0035] Based on the above technical solution, Figure 3 and Figure 4 As shown, the fixing plate 2 also includes a steering knuckle 61 support member 24, and the main body 21 is also provided with a second slot 212, which extends in the vertical direction. One end of the steering knuckle 61 support member 24 is provided in the second slot 212 and can slide in the second slot 212 relative to the main body 21, and the other end abuts against the steering knuckle 61.

[0036] Different models of steering knuckles 61 have corresponding structures and sizes that are different. One end of the steering knuckle 61 support member 24 is arranged in the second slot 212, and can slide in the second slot 212 relative to the main body 21 to adjust the position of the steering knuckle 61 support member 24 relative to the main body 21, and relative to the position of the steering knuckle 61 as a support point. When detecting the drag torque, the detection device of the present application requires the brake assembly 6 to be in a vertical state with the ground. Therefore, the other end of the steering knuckle 61 support member 24 is abutted against the steering knuckle 61 to support the brake assembly 6 in a state suitable for detection.

[0037] Alternatively, if Figure 4 As shown, the steering knuckle 61 support member 24 includes a support rod 241, an adjusting bolt 242 and a limit block 243. The limit block 243 is arranged in the second slot 212. The support rod 241 passes through the limit block 243 in a direction close to the brake assembly 6, and one end abuts against the steering knuckle 61. The adjusting bolt 242 passes through the limit block 243 for adjusting the position of the limit block 243 relative to the second slot 212.

[0038] The limit block 243 is arranged at the second slot 212 and can move along the second slot 212 relative to the main body 21. During the movement, the position of the support rod 241 relative to the brake assembly 6 is adjusted to adjust the support point position of the support rod 241 relative to the steering knuckle 61, so that when the support rod 241 abuts against the steering knuckle 61, the brake assembly 6 is vertical to the ground, and the position of the limit block 243 relative to the second slot 212 is determined. The position of the limit block 243 is fixed by tightening the adjustment bolt 242. When the position of the support rod 241 needs to be adjusted again, the adjustment bolt 242 can be loosened to make the limit block 243 move relative to the second slot 212 to adjust the position of the support rod 241. In this way, the steering knuckle 61 support member 24 can be applicable to different models of steering knuckles 61, thereby improving the versatility of the detection device.

[0039] Based on the above technical solution, Figure 1As shown, the synchronous mechanism 4 includes a first synchronous pulley 41, a second synchronous pulley 42 and a synchronous belt 43, the first synchronous pulley 41 is connected to the driving member 5, the second synchronous pulley 42 is connected to the first connecting disk, and the synchronous belt 43 is transmission-connected to the first synchronous pulley 41 and the second synchronous pulley 42.

[0040] Specifically, when the drag torque of the brake assembly 6 is detected, the driving member 5 drives the first synchronous pulley 41 to rotate, and during the rotation process, drives the second synchronous pulley 42 to rotate through the synchronous belt 43 to perform a subsequent detection process.

[0041] Based on the above technical solution, Figure 1 As shown, the universal brake assembly 6 drag torque detection device further includes a second adapter plate 7 , and the second adapter plate 7 is arranged between the first synchronous pulley 41 and the driving member 5 .

[0042] The provision of the second adapter plate 7 can make the connection between the first synchronous pulley 41 and the driving member 5 more compatible and more stable.

[0043] Alternatively, if Figure 1 As shown, the universal brake assembly 6 drag torque detection device also includes a sleeve column 8, and the number of the sleeve columns 8 is multiple, one end of the multiple sleeve columns 8 is connected to the brake assembly 6, and the other end is connected to the first adapter plate 3.

[0044] Specifically, multiple sleeves 8 are evenly distributed between the brake assembly 6 and the first adapter plate 3 along the circumference of the first adapter plate 3, and play a connecting role between the brake assembly 6 and the first adapter plate 3. The number of sleeves 8 is multiple and evenly distributed, so that the force of the brake assembly 6 on the first adapter plate 3, that is, the second synchronous pulley 42 is evenly distributed, which can better simulate the state of the brake assembly 6 during the operation of the automobile, and can make the final measured drag torque more accurate.

[0045] Alternatively, if Figure 1 As shown, the universal brake assembly 6 drag torque detection device also includes a slide 9, which is arranged on the base 1, and the fixed plate 2 is arranged on the slide 9 to adjust the position of the fixed plate 2.

[0046] Specifically, the setting of the slide 9 enables the fixed plate 2 to move in a direction close to or away from the driving member 5 to adjust the distance between the first synchronous pulley 41 and the second synchronous pulley 42 so that the synchronous belt 43 is in a taut state.

[0047] Alternatively, if Figure 1As shown, the base 1 includes a first base 111 and a second base 121, the driving member 5 is arranged on the first base 111, and the slide 9 is arranged on the second base 121. The second base 121 can move relative to the first base 111, and is used to adjust the radial directions of the first synchronous pulley 41 and the second synchronous pulley 42 to be on the same straight line, so as to improve the accuracy of subsequent detection.

[0048] Optionally, the drag torque detection device of the universal brake assembly 6 further includes a torque sensor, which is disposed on the driving member 5 .

[0049] The setting of the torque sensor can test the torque of the synchronous mechanism 4 during the rotation process to detect the drag torque of the brake assembly 6. The above embodiment mentions that the synchronous belt 43 needs to be in a tight state, and the tight state can be detected by the torque sensor, so that the driving member 5 is idling to detect its idling torque. When the torque sensor detects that the idling torque is less than 0.5N·m, it means that the synchronous belt 43 is in a tight state and can be tested; the zero point torque can also be adjusted to remove the idling torque, which can improve the accuracy of the detection result.

[0050] Specifically, before testing the drag torque of the brake assembly 6, connect the oil pipe to the brake oil inlet hole, and exhaust the air in the brake by manual pressurization. During the test, the hydraulic cylinder is pressurized with 7 MPa hydraulic pressure, pushing the brake piston to the braking state, and releasing the pressure after 5 seconds. This operation is repeated ten times; it is placed statically for 120 seconds in a pressure-free state; after 120 seconds, the driving member 5 rotates at a speed of 50 r / min, driving the first synchronous pulley 41 to rotate, and at the same time driving the second synchronous pulley 42 to rotate through the synchronous belt 43. At this time, the maximum torque of the first and tenth circles during the rotation process is detected, which is the drag torque of the brake assembly 6.

[0051] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
