[0037] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0038] See also Figure 1-Figure 4 This embodiment discloses a torque converter fixing structure, including a torque converter body 101 and a flywheel 102 connected to the torque converter body 101, and further comprising:

[0039] A connecting portion 103, wherein the connecting portion 103 is fixedly connected to the torque converter body 101, and a first thread groove is provided in the connecting portion 103;

[0040] A threaded column 104, one end of which is connected to the torque converter body 101 through a first thread groove, and the other end of which is used to pass through a mounting hole provided on the flywheel 102 and then extend to the outside of the flywheel 102;

[0041] A locking nut 105, wherein the locking nut 105 is used to be threadedly connected to an end of the threaded column 104 away from the torque converter body 101 so that the torque converter body 101 is fixedly mounted on the flywheel 102;

[0042] The fixing mechanism 114 is installed on a side of the flywheel 102 away from the torque converter body 101 and is used to limit the locking nut 105 .

[0043] In the present invention, when assembling the flywheel 102 and the torque converter body 101, one end of the threaded column 104 is connected to the torque converter body 101 through the first threaded groove, and then the threaded column 104 is extended to the outside of the flywheel 102 through the mounting hole provided on the flywheel 102, and finally the locking nut 105 is matched with the threaded column 104 to connect the torque converter body 101 to the flywheel 102; the threaded column 104 connected to the torque converter body 101 can guide the torque converter body 101 during the process of passing through the mounting hole, and the whole process is easy to operate and does not require centering; it avoids the problem of welding nuts on the torque converter body 101 in the prior art. When assembling the flywheel 102 with a through hole, the through hole and the threaded hole of the welding nut need to be aligned. If the through hole and the threaded hole are not aligned, the hole wall of the through hole and the thread will interfere with each other to a certain extent, causing difficulty for workers to operate and reducing the workers' operating efficiency. By setting the fixing mechanism 114, the locking nut 105 that cooperates with the threaded column 104 to fix the flywheel 102 can be further limited, thereby preventing the locking nut 105 from being loosened under the action of a rotating load for a long time, thereby reducing the connection stability between the flywheel 102 and the torque converter body 101, and easily causing the torque converter to fall off, affecting the safety of the device when in use.

[0044] Among them, the fixing mechanism 114 includes a limiting portion 106 and a clamping block 107. The limiting portion 106 is provided with a fixing groove 108 for fixing the locking nut 105, and the clamping block 107 is fixedly connected to the flywheel 102; one end of the limiting portion 106 is rotatably installed on the flywheel 102 through a rotating shaft, and the clamping block 107 is provided with a clamping groove 109, which is used to limit the end of the limiting portion 106 away from the rotating shaft. The rotating shaft is rotatably installed on the flywheel 102 through a bearing. When the locking nut 105 is matched with the threaded column 104, the rotating limiting part 106 makes the limiting part 106 move away from one end of the rotating shaft to the slot 109. The slot 109 limits and fixes the limiting part 106. After the limiting part 106 contacts the slot 109, the fixing groove 108 arranged on the limiting part 106 contacts the locking nut 105 to further fix it. The limiting part 106 is made of a thin metal with a certain elasticity in the prior art.

[0045] Further optimization, the slot 109 is fixedly connected with an arc-shaped protrusion 110, and the end of the limiting part 106 away from the rotating shaft is provided with an arc-shaped groove, and the arc-shaped protrusion 110 is used to limit the limiting part 106 after cooperating with the arc-shaped groove. After the limiting part 106 is rotated so that the end of the limiting part 106 away from the rotating shaft enters the slot 109, the arc-shaped protrusion 110 fixedly connected to the slot 109 contacts the arc-shaped groove provided on the limiting part 106, and the limiting part 106 is further limited and fixed.

[0046] A rubber pad is fixedly connected in the fixing groove 108. After the fixing groove 108 contacts the locking nut 105, the rubber pad can increase the friction between the fixing groove 108 and the locking nut 105, thereby further improving the limiting effect of the fixing groove 108 on the locking nut 105.

[0047] Further optimization, the end of the threaded column 104 away from the torque converter body 101 is fixedly connected with a screw block 111, and the screw block 111 is a polygonal protrusion structure. The provision of the screw block 111 with a polygonal structure can facilitate the connection between the threaded column 104 and the connecting portion 103.

[0048] The screw block 111 is provided with a groove, which can facilitate positioning of the screw block 111 during the rotation of the screw block 111, so that the operator can rotate the screw block 111 more conveniently and labor-savingly to connect the screw block 111 to the connecting portion 103.

[0049] Further optimization is that the diameter of the screw block 111 is smaller than the diameter of the threaded column 104. By making the diameter of the screw block 111 smaller than the diameter of the threaded column 104, it is convenient for the operator to rotate the screw block 111 to connect the screw block 111 with the connecting portion 103, and it is also convenient for the locking nut 105 to cooperate with the threaded column 104.

[0050] A limiting platform 112 is fixedly connected to the threaded column 104 for limiting the position of the threaded column 104. The limiting platform 112 can prevent the threaded column 104 from being excessively screwed into the connecting portion 103 during the process of rotating the threaded column 104 to connect the threaded column 104 with the connecting portion 103, causing the threaded column 104 to excessively squeeze the torque converter body 101, resulting in the torque converter body 101 being damaged by the threaded column 104.

[0051] Further optimization, a clearance hole 113 is provided on the flywheel 102, and after the flywheel 102 is connected to the torque converter body 101, the limit platform 112 is arranged in the clearance hole 113. By providing the clearance hole 113, the torque converter body 101 and the flywheel 102 can be connected more tightly.

[0052] The width of the limiting platform 112 is smaller than the thickness of the flywheel 102. By making the width of the limiting platform 112 smaller than the thickness of the flywheel 102, there is no interference between the connecting portion 103 and the flywheel 102, and the connecting portion 103 is close to the flywheel 102 to fix the flywheel 102.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
