[0002] Reducing the friction of the engine timing guide is the key to ensuring the engine efficiency and extending its service life. To achieve this goal, first, it is necessary to ensure proper lubrication between the guide and the chain or belt, and use high-quality engine oil. Second, it is necessary to regularly clean the guide and the chain or belt, remove sludge and dirt, check and maintain the appropriate tension of the timing chain, select materials with a low coefficient of friction to manufacture the guide, perform regular maintenance, check and replace worn parts, and ensure the dynamic balance of the engine rotating parts, which can significantly reduce the friction of the engine timing guide and improve the engine performance;

[0003] To further reduce friction losses, it is necessary to apply lubricating oil to the chain in a timely manner. However, as the usage time of the oil-injected chain increases, the oil will gradually dry out and become ineffective, making it difficult to lubricate the chain for a long time. Therefore, the utility model provides an oil storage friction lining plate to solve the above problems. Summary of the Utility Model

[0022] The following further describes the present utility model in conjunction with embodiments.

[0023] Please refer to Figures 1-4 , this utility model provides an oil storage type friction lining, which includes a guide rail bracket 1 and a friction lining 2. An installation groove 11 is provided on the guide rail bracket 1, and the friction lining 2 is installed in the installation groove 11. Plug-in slots 111 are provided on both sides at the end of the installation groove 11, and avoidance grooves 112 are provided on one side of the plug-in slots 111 far from the middle of the guide rail bracket 1;

[0024] Specifically, the plug-in slot 111 can allow the plug-in strip 21 to move to a position aligned with the avoidance groove 112 to achieve the plugging of the plug-in strip 21 and the avoidance groove 112.

[0025] Furthermore, plug-in strips 21 corresponding to the avoidance grooves 112 are provided on both sides at the end of the friction lining 2;

[0026] Specifically, when the plug-in strip 21 is embedded in the avoidance groove 112, it can prevent the friction lining 2 from directly slipping out of the installation groove 11.

[0027] Furthermore, a slope surface 211 for guiding the plug-in strip 21 to be embedded in the avoidance groove 112 is provided at one end of the plug-in strip 21 far from the middle of the friction lining 2;

[0028] Specifically, the slope surface 211 can reduce the resistance when the plug-in strip 21 is embedded in the avoidance groove 112 and avoid damage during the assembly process.

[0029] Furthermore, a guiding slope surface 22 for guiding the friction lining 2 to be embedded in the installation groove 11 is provided at the corners of the friction lining 2;

[0030] Specifically, by providing the guiding slope surface 22 at the corners of the friction lining 2, the friction resistance during assembly can be effectively reduced, making it easier for the friction lining 2 to be embedded in the installation groove 11. At the same time, it also helps to protect the surfaces of the friction lining 2 and the installation groove 11 and avoid damage during the assembly process.

[0031] Furthermore, chamfered surfaces 23 for guiding the friction lining 2 to be embedded in the installation groove 11 are provided at the lower edges on both sides of the friction lining 2;

[0032] Specifically, the design of the chamfered surface 23 helps to reduce the friction force between the friction lining 2 and the installation groove 11, enabling the friction lining 2 to slide into the installation groove 11 more smoothly.

[0033] Furthermore, the upper side of the friction lining 2 is gradually narrowed from the central axis to both sides;

[0034] Specifically, the middle of the friction lining 2 bulges, which is beneficial to the dispersion of the oil from the central axis of the friction lining 2 to both sides, enabling the outer link plates of the chain to fully contact the oil.

[0035] Further, a plurality of oil storage holes 24 are provided at the edge of the friction lining plate 2, and the oil storage holes 24 are located in the area between the outer link plate of the chain and the edge 12 of the guide rail bracket 1;

[0036] Specifically, during the transmission of the chain, the oil will be carried by the movement of the chain into the oil storage holes 24 for storage. It should be noted that since the edge 12 of the guide rail bracket 1 contacts the outer link plate of the chain first, and the outer link plate is smaller than a normal chain, even if the guide rail bracket 1 and the chain come into contact due to swinging during use, there will still be a certain distance between the edge of the friction lining plate 2 and the chain that does not come into contact. Adding the oil storage holes 24 in this area will not affect the normal operation of the chain.

[0037] Further, the oil storage holes 24 are in a circular, oval, diamond or strip structure;

[0038] Specifically, the circular oil storage holes 24 can evenly distribute the oil, reducing the situation of too little or too much local oil. The oval oil storage holes 24 can provide a longer contact area, which helps to more effectively distribute the oil in a specific direction. The diamond oil storage holes 24 can provide better structural stability in some cases, especially in applications where it is necessary to maximize the oil storage area in a limited space. The strip oil storage holes 24 can provide a continuous oil supply and are suitable for situations where continuous lubrication is required along a specific direction.

[0039] Working principle: During use, oil is injected onto the friction lining plate 2. The oil flows downward along the direction of the friction lining plate 2 under the action of gravity. Moreover, the middle part of the friction lining plate 2 bulges, which is beneficial to the dispersion of the oil from the central axis of the friction lining plate 2 to both sides, enabling the outer link plate of the chain to fully contact the oil. The oil will be carried by the movement of the chain into the oil storage holes 24 for storage, so that the chain is fully lubricated, playing a role in reducing friction. And during the process of the oil on the chain gradually drying up, the stored oil can be timely supplemented under the action of tension, extending the duration of effective lubrication.
