[0002] The engine clutch driven plate is one of the key components of the clutch, also known as the friction plate. It mainly transfers the engine's torque to the transmission through friction conversion, thereby reducing the vibration and impact of the transmission system. This component is an indispensable and consumable part in automobiles, especially manual transmission step-speed vehicles. In order to make the clutch engage smoothly and ensure smooth car start-up, the driven plate should have axial elasticity. When installing the clutch driven plate, the driven plate and the flywheel plate need to be installed coaxially, and therefore the engine clutch driven plate installation coaxial tooling is required.

The clutch installation auxiliary centering tool according to the embodiment of the utility model is not only simple in structure and easy to use, and can improve installation efficiency, but also has accurate positioning, and can improve the assembly quality of the whole vehicle."

[0004] However, the clutch installation auxiliary centering tooling in the above-mentioned public document mainly considers improving the installation efficiency and accurate positioning, which can improve the assembly quality of the whole vehicle. It is not convenient to lubricate the clutch flywheel disc and reduce the friction. Because the existing tooling does not have the function of lubricating the clutch flywheel disc, it is unable to reduce the friction resistance of the flywheel disc during operation, and accelerates the wear of the flywheel disc.

[0005] In view of this, it is necessary to develop a lubrication mechanism so as to lubricate the clutch flywheel disc and reduce friction. Utility Model Content

[0016] 1. The utility model lubricates the clutch flywheel disc and reduces friction by installing a lubrication mechanism. The existing tooling does not have the function of lubricating the clutch flywheel disc, and is unable to reduce the friction resistance of the flywheel disc when working, but accelerates the wear of the flywheel disc. Therefore, it is necessary to improve this, and then reduce the friction resistance to help the engine flywheel disc start more smoothly, especially in cold start or heavy load conditions. At the same time, it can reduce the direct contact between the flywheel disc and other components, thereby reducing wear. First, the plug is removed from the oil filling hole, and then the lubricating oil flows through the oil filling hole to the bottom of the oil outlet partition, and then the plug is adsorbed by the first magnetic block and the second magnetic block to seal the oil filling hole. When installing the driven disc, the staff can press the control button to make the solenoid valve work, so that the oil outlet hole is in circulation, and the lubricating oil flows into the inner wall of the clutch flywheel disc through the oil outlet hole, thereby reducing the friction between the clutch flywheel disc and other components and increasing the service life of the flywheel disc.

[0017] 2. The utility model is provided with a convenient installation mechanism, which makes it convenient to coaxially install the engine clutch driven plate and the flywheel plate. The handle is used for the staff to hold the driven plate for installation, and the length of the handle is fixed. When the clutch flywheel plate is far away at a specific position, the handle is not long enough, which makes it difficult for the staff to conveniently install the driven plate. Therefore, it is necessary to facilitate the installation of the driven plate. Then, one end of the extension rod is pulled, and the moving block moves in the extension groove, so that the moving block fits with the anti-drop block. The locking rod of the part is fixed to the locking groove through the corresponding locking through hole, so that the position of the extension rod is fixed, and the length of the handle is lengthened, which makes it convenient for the staff to hold it. At the same time, the lighting pole drives the lighting lamp board to move, and the lighting lamp board can be used to illuminate the installation position of the clutch driven plate and the flywheel plate under insufficient light conditions, thereby further improving the convenience of installation of the driven plate for observation.
