Technical Field

[0001] This utility model relates to the field of testing technology for electromechanical braking systems of commercial vehicles, specifically a tensile testing fixture for testing electromechanical braking systems of commercial vehicles. Background Technology

[0002] Commercial vehicle electromechanical braking system (EMB) testing is a process of verifying the performance, functional safety, and environmental adaptability of the EMB system using specialized equipment and methods. Its core objective is to ensure the reliability and stability of the EMB in scenarios such as service braking and parking braking, while meeting the requirements of regulations (such as GB 38900) and industry standards (such as group standard T / CATSI 02-2023).

[0003] Conventional tensile testing fixtures often suffer from insufficient structural stability, inadequate protective measures, and poor adjustment flexibility when used in testing electromechanical braking systems for commercial vehicles. For example, some traditional fixtures are prone to displacement or loosening during testing, which not only affects the accuracy of test results but may also pose safety hazards to testing personnel. Furthermore, the lack of effective physical protective devices means that under extreme testing conditions, accidental splashes or fragments could injure operators. Utility Model Content

[0004] The purpose of this invention is to provide a tensile testing fixture for testing the electromechanical braking system of commercial vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing fixture for testing the electromechanical braking system of commercial vehicles, comprising an electronically controlled test bench and a protective component. A gantry frame is vertically mounted on one end of the top of the electronically controlled test bench. The protective component is vertically installed on the front side of the gantry frame. Adjustable frame components are symmetrically mounted vertically on the left and right sides of the gantry frame near its vertical central axis. A traction component is vertically installed in the middle of the lower part of the gantry frame. The protective component includes a protective plate, an explosion-proof film, a reinforcing frame, and a fixing frame. The front and rear surfaces of the protective plate are covered with an explosion-proof film, and a reinforcing frame is provided on the side of the protective plate. Fixing frames are connected and installed at the four opposite corners of the reinforcing frame near the gantry frame.

[0006] Furthermore, the gantry frame components include a main frame, fixed seats, support angle plates, and anchor bolts. Fixed seats are symmetrically installed on the bottom of the main frame, and support angle plates are symmetrically connected to the lower side of the upper end of the main frame. Anchor bolts are symmetrically installed vertically on the bottom side of the middle upper part of the main frame.

[0007] Furthermore, the main frame, the fixed base, and the supporting corner plate are welded together, and the fixed base has vertical holes for bolt installation at the four opposite corners. The anchor bolts, together with external metal wires, are used to assist in fixing the test object.

[0008] Furthermore, the fixing frame has multiple sets of holes for bolt installation on the side away from the reinforcing frame, and is connected to the front surface of the left and right ends of the main frame. The protective plate and the reinforcing frame are integrated into one structure.

[0009] Furthermore, the adjustment structure includes a support rail, a slider, a positioning bolt, a stabilizing bracket, and an upper tension sensor. The slider is connected to and installed on the surface of the support rail, and positioning bolts are threaded horizontally installed on both sides of the slider. The stabilizing bracket is horizontally connected and installed on the side of the slider away from the support rail, and an upper tension sensor is installed on the top of the end of the stabilizing bracket away from the slider.

[0010] Furthermore, the support guide rail and the slider are connected and combined with each other using a slotted embedded structure.

[0011] Furthermore, the traction component includes a support frame, a lifting traction machine, a traction seat, and a pull-down force sensor. The lifting traction machine is vertically mounted on the front side of the support frame, and the traction seat is connected to the power output of the lifting traction machine in the middle.

[0013] This utility model provides a tensile testing fixture for testing electromechanical braking systems of commercial vehicles, which has the following advantages: 1. This utility model features a protective component installed on the front side of the gantry frame. The protective plate is made of transparent, high-strength material, and explosion-proof films are applied to both sides of the protective plate. This design ensures the operator's safe visibility during testing and effectively prevents injury from accidental debris splashes.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1 to 5As shown, a tensile testing fixture for testing the electromechanical braking system of a commercial vehicle includes an electronically controlled test bench 1 and a protective component 3. A gantry frame 2 is vertically mounted on one end of the top of the electronically controlled test bench 1. The protective component 3 is vertically installed on the front side of the gantry frame 2. Adjustable frame components 4 are symmetrically mounted vertically on the side of the gantry frame 2 closest to its vertical central axis. A traction component 5 is vertically installed in the middle of the lower part of the gantry frame 2. The protective component 3 includes a protective plate 301, an explosion-proof film 302, a reinforcing frame 303, and a fixing bracket 304. The front and rear surfaces of the protective plate 301 are covered with... The explosion-proof membrane 302 and the protective plate 301 are provided with a reinforcing frame 303 on the side. The reinforcing frame 303 has four opposite corners connected to and installed with fixing brackets 304. The fixing brackets 304 have multiple sets of holes for bolt installation on the side away from the reinforcing frame 303, connecting to the front surfaces of the left and right ends of the main frame 201. The protective plate 301 and the reinforcing frame 303 are integrally formed. The gantry frame 2 includes the main frame 201, fixing bases 202, support corner plates 203, and anchor bolts 204. The bottom of the main frame 201 is symmetrically equipped with fixing brackets 204. The main frame 201 has a fixed base 202, and the upper and lower sides of the main frame 201 are symmetrically connected with support angle plates 203. Anchor bolts 204 are symmetrically and vertically threaded onto the lower side of the upper middle part of the main frame 201. The main frame 201, fixed base 202, and support angle plates 203 are welded together. The fixed base 202 has vertical holes at its four opposite corners for bolt installation. The anchor bolts 204, in conjunction with external metal wires, assist in fixing the test object. The use of anchor bolts 204 in conjunction with external metal wires allows for flexible adjustment according to the specific shape and size of the test object. The overall structure ensures that the test object remains stable throughout the test, improving the accuracy and reliability of the test. At the same time, the welded connection between the main frame 201, the fixed seat 202 and the support corner plate 203, as well as the bolt mounting hole structure on the fixed seat 202, further enhance the overall stability and load-bearing capacity of the gantry frame component 2. The explosion-proof film 302 covering the front and rear surfaces of the protective plate 301 can not only effectively prevent injury caused by accidental fragments, but its special material can also absorb and disperse the impact force to a certain extent, providing more reliable safety protection for operators.

[0019] like Figures 1 to 5As shown, the adjusting frame component 4 includes a support guide rail 401, a slider 402, a positioning bolt 403, a stabilizing bracket 404, and an upper tension sensor 405. The slider 402 is mounted on the surface of the support guide rail 401, and positioning bolts 403 are threaded horizontally mounted on both sides of the slider 402. The stabilizing bracket 404 is horizontally mounted on the side of the slider 402 away from the support guide rail 401, and the upper tension sensor 405 is mounted on the top of the end of the stabilizing bracket 404 away from the slider 402. The support guide rail 401 and the slider 402 are interconnected using a slotted embedded structure. The upper tension sensor 405 has multiple sets of holes for bolt mounting on one side of its surface near the vertical central axis of the gantry frame component 2, thus connecting the workpiece being tested. The traction component 5 includes a support frame 501, a lifting traction machine 502, a traction seat 503, and a lower... The tension sensor 504 is mounted vertically on the front of the support frame 501 with a lifting traction machine 502. The middle power output of the lifting traction machine 502 is connected to the traction seat 503, and the tension sensor 504 is mounted on the bottom of the traction seat 503. The support frame 501 has four vertical holes at the four opposite corners for bolt installation. The traction seat 503 has multiple sets of holes for bolt installation to connect the workpiece to be tested. The slotted embedded structure of the support guide rail 401 and the slider 402 allows the stable bracket 404 to move smoothly vertically along the support guide rail 401. This design not only ensures the stability of the upper tension sensor 405 during movement, but also ensures the accuracy of the position of the upper tension sensor 405 during testing through the precise fixing of the positioning bolt 403, thereby improving the reliability of the test data.

[0020] In summary, as Figures 1 to 5 As shown, the tensile testing fixture used for testing the electromechanical braking system of commercial vehicles is first used to securely install the relevant workpieces of the electromechanical braking system of the commercial vehicle to be tested in the hole structure on the surface of the upper tensile sensor 405 near the vertical central axis of the gantry frame 2 and the hole structure on the surface of the traction seat 503 by means of bolt connection to ensure that the connection is firm and reliable and to avoid loosening or falling off during the test. Next, according to the test requirements, by adjusting the position of the slider 402 on the support rail 401, the slider 402 is fixed at a suitable height using the positioning bolt 403, thereby adjusting the vertical position of the upper tension sensor 405 so that it accurately corresponds to the force point of the workpiece being tested. This step ensures that the direction of force transmission during the test is consistent with the actual force direction of the workpiece, thus improving the accuracy of the test. Subsequently, the electric control test bench 1 is started, and the required test parameters, such as tensile force and test time, are set. The electric control test bench 1 will control the lifting traction machine 502 to start working according to the preset program. The lifting traction machine 502 drives the downward force sensor 504 to move upward through the traction seat 503, and applies tensile force to the workpiece being tested. During the test, the upper tension sensor 405 and the lower tension sensor 504 monitor and record the tension data of the workpiece in real time. This data is processed and analyzed by the electronic control test bench 1 to generate a detailed test report. Testers can evaluate the performance of the commercial vehicle's electromechanical braking system based on the data in the report, such as the stability of braking force and response time. Meanwhile, the protective component 3 plays an important safety protection role throughout the testing process. The protective plate 301 and its surface explosion-proof film 302 can effectively block the flying of fragments that may be caused by workpiece breakage or loosening, protecting the personal safety of operators. The reinforcing frame 303 and the fixing frame 304 provide stable support for the protective plate 301, ensuring that it will not deform or shift when subjected to external forces. After the test is completed, the electronic control test bench 1 is turned off, the test workpiece is removed from the tensile test fixture, and the entire test process is summarized and analyzed to provide strong data support for the subsequent design and optimization of the commercial vehicle electromechanical braking system.
