Torque test shelter for transfer case

Abstract

This utility model belongs to the field of transfer case torque testing, specifically relating to a transfer case torque testing protective chamber, including a test workbench. A transfer case is mounted on the top of the test workbench, and a mounting plate is fixedly connected to the bottom of the test workbench. A transmission assembly is mounted on the top of the mounting plate. When testing the transfer case, the user places the transfer case on the top of the test workbench and simultaneously starts the servo motor. The servo motor drives the screw to transmit power, and the large screw drives the synchronous pulley and synchronous belt to rotate, causing both screws to rotate simultaneously. This allows the two gear plates to rotate stably, simultaneously transmitting power to the gear plates, causing the gear plates to drive the gears to rotate. The gear rotation drives the metal rod to rotate, which in turn drives the metal sleeve to rotate. The metal sleeve then drives the protective cover to rotate, allowing the protective cover to close for effective protection.

Description

Technical Field

[0001] This utility model relates to the field of transfer case torque testing technology, specifically a transfer case torque testing protective chamber. Background Technology

[0002] Transfer case torque testing is a specialized test of a vehicle's transfer case's ability to transmit torque under different operating conditions, primarily evaluating its power distribution efficiency, structural strength, and reliability. The test typically simulates various load conditions experienced by the vehicle while driving on a dedicated test bench, such as torque output in low-speed four-wheel drive and high-speed four-wheel drive modes, as well as durability performance under extreme conditions.

[0003] In related technologies, during the current transfer case torque test, strict protective measures must be taken for the outer part of the transfer case to ensure that the transfer case does not experience abnormal shaking due to external forces during the application of torque. Such abnormal shaking may not only affect the accuracy of the test results, but more importantly, it may cause a series of safety hazards and threaten the safety of the operators. Since torque testing itself has a certain degree of risk, if proper protection is not taken, unforeseen dangerous situations may occur during the test.

[0004] Therefore, it is necessary to provide a protective chamber for testing the transfer case torque to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a protective chamber for transfer case torque testing. In current transfer case torque testing, it is necessary to protect the outside of the transfer case to avoid the safety hazard of abnormal shaking during torque testing, which poses a certain degree of danger in the testing process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention relates to a test procedure for a transfer case. The user places the transfer case on top of the test bench and simultaneously starts the servo motor.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The transfer case torque test protective chamber includes a test workbench 1, a transfer case 2 is installed on the top of the test workbench 1, a mounting plate 3 is fixedly connected to the bottom of the test workbench 1, a transmission assembly 4 is installed on the top of the mounting plate 3, a protective cover 5 is installed on the top of the test workbench 1, a metal sleeve 6 is fixedly connected to the rear side of the protective cover 5, a metal rod 7 is fixedly connected inside the metal sleeve 6, a limit plate 8 is fixedly connected to the rear side of the top of the test workbench 1, the limit plate 8 is rotatably connected to the metal rod 7, and a connecting assembly 9 is provided on the surface of the metal rod 7.

[0023] The connecting component 9 is used to rotate the metal rod 7.

[0024] Please see Figure 3 The transmission component 4 includes a servo motor 41, which is fixedly connected to the bottom of the mounting plate 3. Screws 42 are rotatably connected to both sides of the top of the mounting plate 3. Synchronous pulleys 43 are fixedly connected to the bottom of the surface of the screws 42. A synchronous belt 44 is provided on the top of the mounting plate 3 and is connected to the synchronous pulleys 43 for transmission.

[0025] Furthermore, by setting up the transmission component 4, precise and synchronous transmission operations can be achieved for the two screws 42, ensuring that the two screws 42 can stably and efficiently transmit the gear plate 91 during operation. This synchronous transmission mechanism not only greatly improves the working stability of the gear plate 91, but also fundamentally guarantees the smoothness of the gear plate 91 during operation, thus providing users with a convenient and reliable user experience.

[0026] Please see Figure 4 The connecting component 9 includes a toothed plate 91, which is threaded onto the surface of the screw 42. Both ends of the metal rod 7 are fixedly connected to gears 92, and the toothed plate 91 meshes with the gears 92.

[0027] Furthermore, through the reasonable configuration of the connecting component 9, the metal rod 7 can be synchronously and precisely connected and rotated, so that the metal rod 7 remains stable and smooth during rotation. This synchronous connection and rotation mechanism not only enables the metal rod 7 to rotate stably, but also makes it easy for the user to open the protective cover 5, thereby facilitating various tests on the transfer case 2, greatly improving the user's operational convenience.

[0028] Please see Figure 4 Both sides of the top of the test workbench 1 are fixedly connected to the stabilizer 10, and the stabilizer 10 is rotatably connected to the top of the screw 42.

[0029] Furthermore, the stable and reliable stabilizer 10 effectively limits the top of the screw 42, ensuring that the screw 42 maintains high stability during operation and effectively preventing the screw 42 from shaking. This limiting mechanism not only improves the working stability of the screw 42, but also provides users with a safe and reliable operating environment.

[0030] Please see Figure 3 A support plate 11 is fixedly connected to the bottom of the surface of the screw 42, and the support plate 11 is located outside the synchronous pulley.

[0031] Furthermore, the robust and durable support plate 11 provides strong support to the surface of the synchronous pulley, ensuring a high level of support efficiency and effectively preventing the synchronous pulley from detaching from the synchronous belt 44 during operation. This support mechanism not only ensures stable cooperation between the synchronous pulley and the synchronous belt 44 but also provides users with a smooth and efficient user experience.

[0032] Please see Figure 2 The protective cover 5 has several heat dissipation vents 12 on its surface.

[0033] Furthermore, the efficient heat dissipation vents 12 effectively dissipate heat from the surface of the protective cover 5, while also providing good protection for the outside of the transfer case 2. This dual mechanism of heat dissipation and protection not only improves the heat dissipation efficiency of the transfer case 2, but also extends its service life, providing users with more reliable usage assurance.

[0034] Please see Figure 3 A support wheel 13 is rotatably connected to the top of the mounting plate 3, and the support wheel 13 is slidably connected to the timing belt 44.

[0035] Furthermore, the stable and reliable support wheel 13 can effectively tighten the timing belt 44, ensuring that the timing belt 44 maintains good tension during operation and effectively preventing the timing belt 44 from becoming loose. This tightening mechanism not only improves the working stability of the timing belt 44, but also provides users with a stable and efficient operating environment.

[0036] The specific implementation process of this utility model is as follows: To ensure that the performance of the transfer case 2 meets the expected standards, a series of rigorous tests must be conducted on it. First, the user needs to carefully place the transfer case 2 on the top of the test workbench 1 to ensure that it is installed securely. Next, the servo motor 41 is started. The servo motor 41 drives the screw 42 for efficient transmission through precise control. In this process, the transmission role of the large screw 42 is crucial. It can drive the synchronous pulley and the synchronous belt 44 to rotate in a coordinated manner. This rotation mechanism enables the two screws 42 to rotate synchronously, thereby ensuring that the two toothed plates 91 can rotate stably and evenly. Through this synchronous transmission method, two [devices] can be rotated simultaneously. The gear plate 91 performs precise transmission control, enabling it to drive the gear 92 to rotate smoothly. The rotation of the gear 92 further drives the metal rod 7 to rotate, which in turn effectively drives the metal sleeve 6 to rotate. Finally, the rotation of the metal sleeve 6 drives the protective cover 5 to rotate, allowing the protective cover 5 to close smoothly, forming a complete protective system. This design not only ensures the coordinated operation between various components but also provides efficient protection during testing, avoiding damage or safety hazards caused by accidents. In this way, the testing process of the transfer case 2 is not only efficient but also safe and reliable, ultimately achieving the ideal protective effect and ensuring the stability and durability of the equipment in subsequent use.
