Embodiment Construction

[0020] The cylinder block skirt 3 of the present invention is fixed on the lower bottom surface of the cast iron cylinder block by bolts, and the bottom surface of the cylinder body and the top surface of the skirt frame pass through the sealant groove 14 and rely on the sealant to ensure good sealing. As shown in Figures 2 to 4, in addition to being connected to the cylinder block 1, the cylinder block skirt frame 3 is also connected with the oil pump 6 and the rear oil seal cover assembly 7 to form a whole with the rear oil seal cover bolt hole 11 and is provided with The engine oil inlet hole 5; the cylinder block skirt frame 3 is provided with a bolt hole 17 for connecting the oil pump oil pan, and an oil collector bolt hole 16 is installed to connect the oil collector and the oil pan 8. Constitute the crankcase system of engine like this, and the cylinder body skirt frame 3 has played the effect of linking up and down. The cylinder block 1 part supported by the upper part...

Abstract

The invention relates to a new skirt frame for gas cylinder of internal combustion engine, which can be fixed at the bottom face of gas cylinder body of internal combustion engine, whose top face is connected with the bottom face of gas cylinder body by sealing structure, whose bottom face is connected with oil collector and oil bottom shell, and which is integrated with the oil pump and back oil sealing cover assembly. It also comprises that reinforced rib set round bolts connected with bearing cap and gas cylinder in it; reinforced rib set at the back end connected with vehicle gearbox out of it. it also comprises a ribbed plate, by which it is integrated, whose thickness is 2. 5-3. 0mm, which is made of aluminum alloy. The invention can ensure the stability of engine, decrease the engine weight, decrease vibration and noise of engine and decrease producing and repairing cost of engine.

Description

technical field [0001] The invention belongs to the field of power devices, and relates to an internal combustion engine, in particular to the structure of a skirt frame of a cylinder block. Background technique [0002] Cylinder blocks of traditional internal combustion engines are divided into two types: one is the cylinder block made of cast iron, and the crankcase structure of the cylinder block made of cast iron can generally be divided into: gantry type (as shown in Figure 1a), bisected type (as shown in Figure 1b) and Tunnel type (as shown in Figure 1c). The bisected cylinder block means that the center line of the crankshaft and the bottom plane of the cylinder block are on the same plane; the gantry type cylinder block means that the center line of the crankshaft and the bottom plane of the cylinder block are not on the same plane; the tunnel type cylinder block means that the center hole of the crankshaft is completely placed in the cylinder body interior. In ter...
