[0033] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a new type of hydraulic torque converter, the new type of hydraulic torque converter comprises a front cover 1, a rear cover 5, a friction plate 4 installed inside the front cover 1 and the rear cover 5, an impeller 2 installed at one end of the friction plate 4, and a one-way wheel 3 installed inside the impeller 2, a mounting member 6 is installed between the front cover 1 and the rear cover 5, and a connecting member 7 is installed inside the friction plate 4;

[0034] The mounting member 6 includes a first mounting groove 61 provided on the outer surface of the front cover 1 and a second mounting groove 62 provided on the outer surface of the rear cover 5. The first mounting groove 61 and the second mounting groove 62 are symmetrically arranged. A mounting plate 63 is installed inside the first mounting groove 61 and the second mounting groove 62. The mounting plate 63 is arranged in an arc shape. Positioning bolts 64 are installed at both ends of the mounting plate 63. The positioning bolts 64 penetrate the mounting plate 63 and extend to the outer surfaces of the front cover 1 and the rear cover 5 and are threadedly connected. Grooves are provided on the inner sides of both ends of the mounting plate 63, and the diameter of the grooves is consistent with the diameter of the positioning bolts 64, which can facilitate the insertion of the positioning bolts 64. At the same time, a groove is provided at one end of the groove. A circular groove is provided, and its diameter is larger than the groove diameter and consistent with the driving member diameter of the positioning bolt 64, which can facilitate the positioning of the positioning bolt 64, and one end of the positioning bolt 64 is threadedly connected to the outer surface of the front cover 1 and the rear cover 5, and does not extend to the inner side of the two. In this way, it can be prevented from penetrating into the interior of the two, causing internal liquid leakage and causing the work to be unable to proceed normally. The front cover 1 and the rear cover 5 can be initially positioned by corresponding the first mounting groove 61 to the second mounting groove 62, and then the mounting plate 63 is installed, and the purpose of fastening connection can be achieved by the positioning bolt 64. One end of the mounting plate 63 is a protruding middle end, and the other end is a protruding end end.

[0035] The end of the positioning bolt 64 away from the mounting plate 63 is fixedly connected to a knob 65, and the surface of the knob 65 is fixedly connected to rubber blocks 66 arranged equidistantly, which can facilitate the staff to rotate the positioning bolt 64. At the same time, the rubber blocks 66 can increase the friction with the hand, thereby facilitating its rotation, thereby facilitating the installation and disassembly of the mounting plate 63, and at the same time, it can facilitate the installation and disassembly of the front cover 1 and the rear cover 5, further achieving the purpose of fastening the installation and facilitating disassembly. The surface of the mounting plate 63 is provided with a groove, and a handle is installed inside it, which can facilitate the removal of the mounting plate 63.

[0036] During use, the front cover 1 and the rear cover 5 are engaged, and the first mounting groove 61 and the second mounting groove 62 are aligned, and then the mounting plate 63 is pressed into the inside of the first mounting groove 61 and the second mounting groove 62. Due to their consistent shapes, the front cover 1 and the rear cover 5 can be preliminarily positioned, and then the knob 65 is turned to make the positioning bolt 64 pass through the mounting plate 63 and be threadedly connected with the first mounting groove 61 and the second mounting groove 62 to complete the installation operation. When repairing it, the reverse operation can be performed, thereby achieving the purpose of tight installation and simple disassembly, further facilitating the maintenance operation.

[0037] Reference Figure 1-6The connecting member 7 includes a cavity 77 opened inside the friction plate 4, a connecting bolt 71 is installed inside the cavity 77, a retaining ring 72 and a driving ring 75 are threadedly connected on the surface of the connecting bolt 71, and the driving ring 75 is located at the bottom of the retaining ring 72. The setting of the cavity 77 allows the connecting bolt 71 to be located inside the friction plate 4, preventing it from protruding to the outer surface of the friction plate 4, preventing it from being stuck with the impeller 2, and preventing it from causing damage to the impeller 2. The diameter of the cavity 77 is consistent with the diameter of the retaining ring 72, and the retaining ring 72 is located inside the cavity 77.

[0038] The bottom of the retaining ring 72 is movably connected with the first hinge block 73, and the end of the first hinge block 73 away from the retaining ring 72 is movably connected with the second hinge block 74. The second hinge block 74 is movably connected to the driving ring 75. The retaining ring 72 and the driving ring 75 are connected with the first hinge block 73 and the second hinge block 74 through the first hinge block 73. The angle between the first hinge block 73 and the second hinge block 74 can change with the rotation of the connecting bolt 71. When the driving ring 75 is threadedly connected with the connecting bolt 71, it will slowly move toward the retaining ring 72 with the rotation of the connecting bolt 71. At the same time, the corner between the first hinge block 73 and the second hinge block 74 will become an acute angle, and the outer surface of the first hinge block 73 will be stuck with the inner side of the rear cover 5, thereby achieving the purpose of connecting the rear cover 5 and the friction plate 4.

[0039] The interior of the rear cover 5 is fixedly connected with a nut 76, and the bottom of the connecting bolt 71 extends to the interior of the rear cover 5 and is threadedly connected to the nut 76, thereby achieving the purpose of triple connection. First, the friction plate 4 and the rear cover 5 are directly connected by an adhesive, and then the outer surface of the first hinge block 73 is engaged with the inner side of the rear cover 5, and finally, the connecting bolt 71 is threadedly connected with the nut 76 to achieve the purpose of tight connection, thereby further strengthening the connection between the friction plate 4 and the rear cover 5. In addition, the first hinge block 73, the second hinge block 74, and the drive ring 75 all extend to the interior of the rear cover 5.

[0040] The surfaces of the friction plate 4 and the rear cover 5 are coated with adhesive, and the two are adhesively connected. The adhesive is one of epoxy resin and acrylic acid materials.

[0041] A positioning block 78 is fixedly connected to the bottom of the friction plate 4, and a positioning groove 79 is opened on the surface of the rear cover 5. The positioning block 78 is located inside the positioning groove 79 and is movably connected thereto, and can prevent the friction plate 4 from rotating along the surface of the rear cover 5 when the connecting member 7 is installed.

[0042] During use, the friction plate 4 is adhesively connected to the rear cover 5 by an adhesive, and then the connecting bolt 71 is inserted into the interior of the cavity 77 so that the bottom of the retaining ring 72 fits with the interior of the cavity 77, and the connecting bolt 71 is rotated to slowly extend into the interior of the rear cover 5. When the connecting bolt 71 is threadedly connected to the driving ring 75, it will slowly move toward the retaining ring 72 as the connecting bolt 71 rotates, and at the same time drive the second hinge block 74 and the first hinge block 73 to slowly approach each other, and form an acute angle between the two. At this time, the diameter of the outer surface of the first hinge block 73 will be larger than the hole in the rear cover 5, and then the connecting bolt 71 is continued to be rotated to make it threadedly connected with the nut 76, so that the installation of the friction plate 4 can be completed. This method can strengthen the connection between the friction plate 4 and the rear cover 5, and the adhesive can prevent loosening caused by high temperature, thereby prolonging the service life of the friction plate 4 and improving the connection and stability of the friction plate 4 and the rear cover 5. When replacing the friction plate 4, the operation is reversed, thereby simplifying the maintenance and replacement of the friction plate 4.

[0043] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
