[0027] like Figure 1-Figure 4 As shown together, this embodiment provides a combined static sealing gasket suitable for a T-shaped area, comprising an oil pan 1, an engine housing 2 being provided on one side of the upper end of the oil pan 1, a motor housing 3 being provided on the end of the upper end of the oil pan 1 close to the engine housing 2, a sealing assembly 4 being provided on the upper end of the oil pan 1 between the engine housing 2 and the motor housing 3, the sealing assembly 4 comprising a first sealing gasket 41 provided on the upper end of the oil pan 1, a plurality of groups of mutually symmetrical first through holes 42 being evenly provided on the upper end surface of the first sealing gasket 41, a second sealing gasket 44 being provided in the middle of the upper end of the first through hole 42, mutually symmetrical metal protrusions 45 being fixed at both ends of the second sealing gasket 44, intermittent grooves 48 being provided on both sides of the outer wall of the upper end of the metal protrusion 45 of the second sealing gasket 44, and a plurality of groups of mutually symmetrical second through holes 46 being provided on the outer wall of the second sealing gasket 44.

[0028] The engine housing 2 is formed by wrapping a metal thin steel plate with damping paint.

[0029] The first sealing gasket 41 and the second sealing gasket 44 are made of metal aluminum cabinet.

[0030] The first sealing gasket 41 and the second sealing gasket 44 are assembled together by vertical interference fitting to form a T-shaped sealing area.

[0031] A sealing area is provided between the upper surface of the oil pan 1 and the lower surface of the engine housing 2. Sealing areas are provided between the right surface of the motor housing 3 and the upper surface of the oil pan 1 and the left surface of the engine housing 2 respectively. The sealing assembly 4 seals the sealing areas. The inner edge of the first sealing gasket 41 is filled with vulcanized rubber 43, and the inner edge of the second sealing gasket 44 is filled with rubber ribs 47. Several groups of threaded holes matching the first through hole 42 are provided at the lower ends of the motor housing 3 and the engine housing 2. A threaded hole matching the first through hole 42 is provided at the lower end of the oil pan 1. The threaded holes provided in the motor housing 3 and the engine housing 2 correspond to the threaded holes provided in the oil pan 1.

[0032] The inner walls of the engine housing 2 and the motor housing 3 are both provided with threaded holes that match the second through hole 46 , and the threaded holes provided in the engine housing 2 and the motor housing 3 correspond to each other.

[0033] A vulcanization groove 49 is formed on one side of the upper end of the first sealing gasket 41 .

[0034] The sealing area between the oil pan 1, the engine housing 2 and the motor housing 3 can be sealed by the sealing assembly 4. By setting the rubber rib 47, the contact area can be increased and the sealing reliability can be improved. The engine housing 2 and the motor housing 3 are connected by bolts, and the bolts pass through the engine housing 2, the second through hole 46 and the motor housing 3 in sequence. Similarly, the engine housing 2, the motor housing 3 and the oil pan 1 are also connected by bolts, thereby achieving the effect of sealing the fluid in the cavity. When the second sealing gasket 44 is connected to the engine housing 2 and the motor housing 3, the rubber rib 47 on the edge of the second sealing gasket 44 is squeezed between the two housings, and then the oil pan 1 is installed. The rubber rib 47 on the edge of the second sealing gasket 44 is squeezed and sealed again by the vulcanized rubber 43 on the first sealing gasket 41 and the aluminum frame. After multiple compressions, the sealing reliability is improved. During the vulcanization process of the rubber 43, part of the vulcanized rubber 43 flows into the vulcanization groove 49 opened in the first sealing gasket 41, so that the combination of the vulcanized rubber 43 and the first sealing gasket 41 is tighter. The main bodies of the first sealing gasket 41 and the second sealing gasket 44 are metal aluminum frames, and the rubber is filled on the inner wall of the metal aluminum frame by vulcanization, wherein the first sealing gasket 41 and the second sealing gasket 44 are combined into one by assembly. When the engine housing 2 and the motor housing 3 are assembled by bolt locking, the rubber rib 47 at the edge of the second sealing gasket 44 is squeezed and squeezed out. When the motor housing 3 and the oil pan 1 are assembled by bolt locking, a part of the rubber rib 47 extruded at the edge of the second sealing gasket 44 is squeezed again by the vulcanized rubber 43 and the aluminum frame on the second sealing gasket 44, and its sealing reliability is significantly higher than other forms of planar sealing.

In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
