The convex block on the back of the annular push plate collides with the extrusion block during the rotation process, so that the elastic rod is extended, the annular push plate is pushed forward, and the annular push plate slides on the inner wall of the annular bellows to achieve the purpose of squeezing out the air, thereby guiding the air inside the shell, promoting the air flow exchange inside the shell, and achieving the purpose of preventing the torque converter from overheating during rotation, and avoiding the overheating of the oil during use, resulting in the liquid being too low, which will also affect the conversion efficiency; the special-shaped connecting block, the semi-circular plate 1, the small cylinder and the semi-circular plate 2 cooperate with each other. When the convex block on the back of the annular push plate is squeezed forward by the extrusion block, the special-shaped connecting block moves forward under the action of the spring force, and the special-shaped connecting block drives the semi-circular plate 1 to move forward, so that the semi-circular plate 1 and the semi-circular plate 2 are separated, so that the ventilation channel of the small cylinder is opened, so as to further promote the ventilation effect, so that the corners inside the shell can also have airflow passing through, and the heat dissipation effect of the torque converter is comprehensively improved.

[0017] (4) The present invention sets an anti-shrinkage device to make the hollow cylinder, damping rod and annular sealing plate cooperate. In some high or low temperature weather, the oil pipeline used for a long time may cause deformation or material strength due to thermal expansion and contraction, and then rupture and leak. When deformation occurs, the oil pipeline will move closer or separate accordingly, and the oil pipeline will drive the annular sealing plate to move closer or separate accordingly.

Therefore, an expansion joint is added to the oil pipeline 14, and the damping rod 52 is used to control the space between the annular sealing plate 53 and the hollow cylinder 51. Distance, when deformation occurs, the oil pipeline 14 will move closer or separate accordingly, and the oil pipeline 14 will drive the annular sealing plate 53 to move closer or separate accordingly, one end of the damping rod 52 is fixed to the inner wall of the hollow cylinder 51, and the other end of the damping rod 52 is fixed to the side of the annular sealing plate 53 away from the cut-off point, and the deformation is controlled by the extension and contraction of the damping rod 52, so that the process of separation and approach of the oil pipeline 14 is smoother, and the hollow cylinder 51 and the annular sealing plate 53 are used to cooperate and seal to avoid leakage at the cut-off point of the oil pipeline 14.

[0031] The anti-shrinkage device 5 also includes a long screw 54, a pressure plate 55 and an annular rubber 56; the long screw 54 passes through the outer wall of the hollow cylinder 51 and the top surface of the annular sealing plate 53, and the bottom of the long screw 54 is threadedly connected to the top surface of the annular sealing plate 53. When installing the torque converter control system, the long screw 54 can be twisted, and the pressure plate 55 is rotatably installed at the bottom of the long screw 54. The long screw 54 pushes the pressure plate 55, and the pressure plate 55 is slidably installed on the inner wall of the annular sealing plate 53. The annular rubber 56 is fixed on the inner wall of the annular sealing plate 53, and the annular rubber 56 is located on the movement trajectory of the pressure plate 55. The pressure plate 55 squeezes the annular rubber 56, causing the annular rubber 56 to be slightly deformed, and the annular rubber 56 is used to fill the gap between the annular sealing plate 53 and the hollow cylinder 51, so that the sealing effect is better and the leakage is further avoided.

[0032] When in use, the swivel 32 drives the elastic rod 41 to rotate, and the elastic rod 41 drives the annular push plate 42 to rotate. The convex block on the back of the annular push plate 42 collides with the extrusion block 44 during the rotation process, so that the elastic rod 41 is extended, and the annular push plate 42 is pushed forward. The annular push plate 42 slides on the inner wall of the annular bellows 45 to achieve the purpose of squeezing out air, thereby guiding the air inside the shell 31, promoting the air flow exchange inside the shell 31, and achieving the purpose of preventing the torque converter from overheating during rotation, avoiding overheating of the oil during use, resulting in too low a liquid, which will also affect the conversion efficiency; at the same time, when the convex block on the back of the annular push plate 42 rotates to the extrusion block 44 When there is a gap, the elastic rod 41 pulls the annular push plate 42 to retract, the annular push plate 42 pushes the special-shaped connecting block 46, and the special-shaped connecting block 46 pushes the semicircular plate 1 47, so that the semicircular plate 1 47 and the semicircular plate 2 49 are combined and closed. When the convex block on the back of the annular push plate 42 is squeezed forward by the squeezing block 44, the special-shaped connecting block 46 moves forward under the action of the spring force, and the special-shaped connecting block 46 drives the semicircular plate 1 47 to move forward, so that the semicircular plate 1 47 and the semicircular plate 2 49 are separated, so that the ventilation channel of the small cylinder 48 is opened, so as to further promote the ventilation effect, so that air can also pass through the corners inside the shell 31, and the heat dissipation effect of the torque converter is comprehensively improved.

[0033] In some high or low temperature weather conditions, the oil pipeline 14 that has been used for a long time may cause deformation or material strength due to thermal expansion and contraction, and then rupture and leak. Therefore, an expansion joint is added to the oil pipeline 14, and the damping rod 52 is used to control the distance between the annular sealing plate 53 and the hollow cylinder 51. When deformation occurs, the oil pipeline 14 will move closer or separate accordingly, and the oil pipeline 14 will drive the annular sealing plate 53 to move closer or separate accordingly. The deformation is controlled by the extension and contraction of the damping rod 52, so that the separation and approach process of the oil pipeline 14 is smoother, and the hollow cylinder 51 and the annular sealing plate 53 are used to cooperate and seal to avoid leakage at the cutoff point of the oil pipeline 14; when installing the torque converter control system, the long screw 54 can be screwed, and the long screw 54 pushes the pressure plate 55, and the pressure plate 55 squeezes the annular rubber 56, so that the annular rubber 56 is slightly deformed, and the annular rubber 56 is used to fill the gap between the annular sealing plate 53 and the hollow cylinder 51, so that the sealing effect is better and leakage is further avoided.
