By changing the shift lever, it can choose to mesh with different gears so that the two shafts can output different speeds, directions and torques. In the car, the intermediate shaft transfers the rotational force from the engine or transmission to the wheels, and evenly distributes the torque between the two wheels to ensure balanced power transmission and traction. In addition, it provides additional support and stability for the transmission system, helping to minimize vibration and noise. During the production process, the torque performance of the intermediate shaft needs to be tested to ensure the torque performance of the product.

A support frame 4 is fixedly installed on the right side of the top of the detection platform 1, and a detection motor 5 is fixedly installed on the top of the support frame 4. The detection motor 5 provides torque power to the device, and the output end of the detection motor 5 is fixedly connected to a first coupling 6, and the end of the first coupling 6 away from the output end of the detection motor 5 is connected to a torque sensor 7, and the end of the torque sensor 7 away from the first coupling 6 is connected to a second coupling 8, and the end of the second coupling 8 away from the torque sensor 7 is fixedly connected to the right end of the fixed frame 11, and motion and torque are transmitted through the first coupling 6 and the second coupling 8 to ensure that power is effectively transmitted to the intermediate shaft, and at the same time, it plays a role of buffering and vibration reduction to protect the intermediate shaft and other related components from damage, and the torque value transmitted is directly detected by the torque sensor 7 to measure the data, and a fixing plate 9 is fixedly installed on the left side of the top of the detection platform 1.
[0021] Furthermore, two fixing components 10 are fixedly connected at equal distances to the left end of the testing platform 1, a fixing frame 11 is fixedly connected to the middle part of the left end of the testing platform 1, a fixing groove 12 is opened in the middle part of the top of the fixing frame 11, the intermediate shaft is fixed by the fixing frame 11 and the fixing groove 12, a connecting groove 13 is opened in the middle of the fixing plate 9, the position of the second coupling 8 corresponds to the position of the connecting groove 13, the connecting groove 13 ensures the accuracy of the connection position between the intermediate shaft and the second coupling 8, a mounting block 14 is fixedly connected to the left end of the fixing frame 11, a mounting groove 15 is opened at the left end of the mounting block 14, and it is supported and reinforced by the mounting block 14 and the mounting groove 15.
[0022] Further, such as Figure 3 As shown, the fixing assembly 10 includes a connecting block 101, a cylinder 102 is fixedly mounted on the top of the connecting block 101, the stability of the cylinder 102 during installation is ensured by the connecting block 101, and a clamping block 103 is fixedly connected to the output end of the cylinder 102, and the clamping block 103 is moved by the push of the cylinder 102.
[0023] Further, such as Figure 4 As shown, the connecting block 101 is fixedly connected to the left end of the detection platform 1, and the clamping block 103 is located between the fixing frame 11 and the fixing plate 9.
