[0018] Example 1

[0019] like Figure 1 As shown, an AMT clutch and pneumatic actuator test device includes a clutch mounting plate 5 and a pneumatic actuator mounting plate 7. The clutch mounting plate 5 is used to assemble the clutch, and the pneumatic actuator mounting plate 7 is used to assemble the pneumatic actuator. In this embodiment, the clutch and the pneumatic actuator are not shown.

[0020] like Figure 1 As shown, the clutch mounting plate 5 is mounted on the base plate 10, and the pneumatic actuator mounting plate 7 is mounted on the adjustment plate 9. The mounting position of the adjustment plate 9 on the base plate 10 is adjustable, so that the distance between the clutch mounting plate 5 and the pneumatic actuator mounting plate 7 is adjustable.

[0021] Among them, when the adjustment plate 9 drives the pneumatic actuator mounting plate 7 away from the clutch mounting plate 5, the distance between the clutch mounting plate 5 and the pneumatic actuator mounting plate 7 is expanded, which can facilitate the disassembly and assembly operations during the clutch and pneumatic actuator testing; in addition, when the adjustment plate 9 drives the pneumatic actuator mounting plate 7 close to the clutch mounting plate 5, the axial fitting dimensions between the clutch and the pneumatic actuator can be controlled, which is convenient for testing.

[0022] Specifically, such as Figure 1 As shown, the clutch mounting plate 5 is connected to the base plate 10 through the fixing seat 6. The fixing seat 6 includes an L-shaped plate and a reinforcing plate. One end of the L-shaped plate of the fixing seat 6 is connected to the clutch mounting plate 5 through a fixing bolt, and the other end is connected to the base plate 10 through a fixing bolt. The reinforcing plate of the fixing seat 6 is triangular in shape and is connected to the bending part of the L-shaped plate of the fixing seat 6 to improve the stability of the L-shaped plate.

[0023] In addition, if Figure 3 As shown, a pad 14 is disposed on the clutch mounting plate 5 , and the performance of the clutch assembly under different wear conditions is simulated by adjusting the thickness of the pad 14 .

[0024] like Figure 1As shown, the adjustment plate 9 is connected to the base plate 10 through the adjustment seat 12. The adjustment seat 12 includes an L-shaped plate and a reinforcement plate. One end of the L-shaped plate of the adjustment seat 12 is connected to the adjustment plate 9 through a fixing bolt, and the other end is connected to the base plate 10 through a fixing bolt. The reinforcement plate of the adjustment seat 12 is triangular and connected to the bending part of the L-shaped plate of the adjustment seat 12 to improve the stability of the L-shaped plate. Specifically, as Figure 2 As shown, the bottom of the adjustment seat 12 is connected to a guide block 13, and an L-shaped slot is provided on the guide block 13. Correspondingly, a guide groove 11 adapted to the L-shaped slot is opened on the base plate 10, so that the adjustment plate 9 drives the pneumatic actuator mounting plate 7 to adjust its position on the base plate 10, thereby adjusting the distance between the pneumatic actuator mounting plate 7 and the clutch mounting plate 5.

[0025] In addition, an upper air hole 8 for communicating with an air source is provided on the pneumatic actuator mounting plate 7, which is used to adjust the internal pressure of the pneumatic actuator to enable the pneumatic actuator to push the clutch to disengage and engage.

[0026] like Figure 1 As shown, a screw rod 2 is further disposed between the clutch mounting plate 5 and the pneumatic actuator mounting plate 7. The screw rod 2 is sequentially inserted into the center hole of the adjustment plate 9, the center hole of the pneumatic actuator mounting plate 7, the center hole of the clutch mounting plate 5, and the center hole of the screw adjustment support 1. A limit nut 4 is sleeved on the screw rod 2 between the clutch mounting plate 5 and the screw adjustment support 1 to adjust the position of the screw rod 2. Separation nuts 3 are sleeved on the screw rod 2 on both sides of the screw adjustment support 1. One end of the screw rod 2 is connected to the adjustment plate 9 via a fixing bolt, and the other end is connected to the screw adjustment support 1 via a separation nut 3.

[0027] Working principle: Before the test starts, the AMT clutch and pneumatic actuator test device fixes the clutch to the clutch mounting plate 5 and the pneumatic actuator to the pneumatic actuator mounting plate 7. When installing the clutch, a pad 14 is set between the clutch and the clutch mounting plate 5.

[0028] Then, insert the screw 2 in sequence through the center hole of the adjustment plate 9, the center hole of the pneumatic actuator mounting plate 7, the center hole of the clutch mounting plate 5, and the center hole of the screw adjustment support 1. A limit nut 4 is fitted onto the screw 2 between the screw adjustment support 1 and the clutch mounting plate 5. Separation nuts 3 are fitted onto the screw 2 on both sides of the screw adjustment support 1. One end of the screw 2 is connected to the adjustment plate 9 via a fixing bolt, and the other end is secured to the screw adjustment support 1 by tightening the separation nuts 3. The limit nut 4 is used to adjust the position of the screw 2 so that the pneumatic actuator is installed in place.

[0029] During the test, the upper air hole 8 on the pneumatic actuator mounting plate 7 is connected to the air source, and the test software receives the position sensor signal from the pneumatic actuator and realizes the process of the pneumatic actuator pushing the clutch to disengage and engage by adjusting the internal pressure of the pneumatic actuator.
