Technical Field
[0001] This utility model belongs to the field of automotive technology, and more specifically, it relates to an engine timing cover. Background Technology
[0002] The timing cover is typically installed at the front of the engine, forming a sealed space with the cylinder head and cylinder head cover to protect the timing system from contamination or impact. The structural design and bolt hole distribution of the timing cover are particularly important for the engine's stability and reliability. Currently, timing covers in use have a lower mounting platform mode, and many of the reinforcing ribs on the timing cover use a through-type reinforcing rib structure, making the timing cover's structure relatively complex and its weight heavier.

[0005] Furthermore, the top of the cover body is provided with an upper mounting surface, which has three upper mounting holes; the bottom of the cover body is provided with a lower mounting surface, which has four lower mounting holes.
[0006] Furthermore, the cover body has side mounting surfaces on its left and right sides, and side mounting holes are respectively opened on the side mounting surfaces.
[0007] Furthermore, the outer side of the suspension mounting platform is provided with arc-shaped surfaces on the left and right sides respectively.
[0008] Furthermore, the lower reinforcing rib includes an arc-shaped rib plate disposed on one side of the pulley mounting hole, the arc-shaped rib plate being connected with a plurality of straight rib plates at intervals along its length, and the arc-shaped connecting plate being connected to the outer wall of the pulley mounting hole through the plurality of straight rib plates.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can effectively improve the modality of the suspension mounting platform by installing reinforcing ribs, fixing columns and connecting columns in the inner groove of the suspension mounting platform. At the same time, this utility model further improves the modality of the suspension mounting platform by providing arc-shaped surfaces on the left and right sides of the outer side of the suspension mounting platform.
[0010] 2. The structure of this utility model is simple. It does not use a through-type reinforcing rib structure. By setting upper and lower reinforcing ribs, the mode and strength of the suspension mounting platform and pulley mounting hole are guaranteed, thereby effectively enhancing the overall structural strength of the cover body. At the same time, this utility model is lighter in weight. Attached Figure Description
