[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5 As shown, it relates to an automobile clutch which is easy to install, including a housing 1 and a flywheel 3. A mounting plate 2 is fixedly connected to the side of the housing 1, and the mounting plate 2 and the housing 1 are an integral structure. Two symmetrical clamping hole structures 4 are opened on the side of the mounting plate 2, and two positioning components 5 inserted into the clamping hole structures 4 are arranged on the side of the flywheel 3. A diaphragm spring 6, a pressure plate 8 and a friction plate 9 are arranged inside the housing 1.

[0023] The clamping hole structure 4 includes a first circular hole 41 and a second circular hole 42, and the diameter of the first circular hole 41 is larger than that of the second circular hole 42. A connecting groove is provided between the first circular hole 41 and the second circular hole 42. The positioning assembly 5 includes a positioning column 51 fixed to the side of the flywheel 3, and the positioning column 51 can be inserted into the first circular hole 41 and the second circular hole 42. The diameter of the positioning column 51 is the same as that of the second circular hole 42 and smaller than that of the first circular hole 41.

[0024] The positioning post 51 can be first inserted into the first circular hole 41 , and then the housing 1 and the mounting plate 2 are rotated to move the positioning post 51 into the second circular hole 42 , so that the mounting plate 2 can be positioned.

[0025] A circular card 52 is fixed on one end of the positioning column 51 away from the flywheel 3 . The diameter of the card 52 is smaller than the diameter of the first circular hole 41 and larger than the diameter of the second circular hole 42 .

[0026] Since the diameter of the card 52 is smaller than the first circular hole 41, it will not affect the insertion of the positioning column 51 into the first circular hole 41. When the positioning column 51 moves into the second circular hole 42, since the diameter of the card 52 is larger than the diameter of the second circular hole 42, the mounting plate 2 cannot be separated from the positioning column 51, thereby achieving the pre-fixation of the mounting plate 2 and the housing 1. In this embodiment, the length of the positioning column 51 is the same as or slightly smaller than the thickness of the mounting plate 2, so that the mounting plate 2 can be fixed after being stuck between the flywheel 3 and the card 52, which is conducive to the subsequent installation of the bolts.

[0027] The diaphragm spring 6 is fixedly connected to the housing 1 through rivets and spring steel sheets, and a release hook 7 is fixed to the side of the diaphragm spring 6, and the other end of the release hook 7 is fixedly connected to the side of the pressure plate 8, and the friction plate 9 is located between the pressure plate 8 and the flywheel 3.

[0028] After the housing 1 is fixed on the surface of the flywheel 3, the diaphragm spring 6 squeezes the pressure plate 8, and the pressure plate 8 squeezes the friction plate 9 to fit the flywheel 3, so that the flywheel 3 can drive the friction plate 9 to rotate.

[0029] A spline groove is provided in the middle of the friction plate 9. The spline groove is used to pass through the input shaft of the gearbox so that the friction plate 9 can drive the input shaft of the gearbox to rotate.

[0030] The side of the mounting plate 2 is provided with a plurality of first connection holes 10, and the side of the flywheel 3 is provided with a plurality of second connection holes 11 matching the first connection holes 10. By screwing bolts into the first connection holes 10 and the corresponding second connection holes 11, the mounting plate 2 and the flywheel 3 are finally fixedly connected.

[0031] Working principle: When installing the clutch, first fit the housing 1 and the mounting plate 2 with the flywheel 3, and let the positioning column 51 and the card 52 pass through the first circular hole 41 on the mounting plate 2, then rotate the mounting plate 2 and the housing 1 so that the positioning column 51 is stuck in the second circular hole 42, thereby pre-fixing the mounting plate 2 and the housing 1. At this time, the first connecting hole 10 on the mounting plate 2 is just aligned with the second connecting hole 11 on the flywheel 3, and then the mounting plate 2 and the flywheel 3 are fixedly connected by bolts. The clutch can be operated by one person during installation, and the installation is simpler and more convenient. The working principle of the clutch is the same as that of the prior art, which will not be repeated here.

[0032] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
