A control system combining dynamic and static devices in the technical field of mechanical design, including a control body, a centrifugal shaft, a centrifugal chamber, a centrifugal body, a centrifugal spring, an arc plate, and an elastic band. One end of the rod is consolidated with the upper end of the valve body. The centrifugal chamber, centrifugal body, centrifugal spring, arc plate and elastic band are all arranged in the control body. One end of the centrifugal body is arranged in the centrifugal chamber and connected to the centrifugal shaft through the centrifugal spring. Connection, the other end of the centrifugal body is a circular arc structure, the other end of the centrifugal body is in sealing contact with the circular arc plate, and the elastic band is arranged on the outer surface of the circular arc plate. When the engine speed is high, the valve body moves up, the main oil passage is separated from the oil return pipe, and the oil pressure in the main oil passage increases; when the engine speed is low, the valve body moves down, and the main oil passage is connected with the oil return pipe. The oil pressure in the main oil gallery decreases. The invention has reasonable design and simple structure, and is suitable for the optimized design of the mechanical lubricating system.
Description
technical field [0001] The invention relates to a lubricating adjustment system in the technical field of mechanical design, in particular to a dynamic and static device combination control system suitable for supercharged engines. Background technique [0002] When the engine is working, the speed is very high, and the parts between the piston and the cylinder wall, between the connecting rod bearing bush and the crankshaft are tightly matched. If these matching parts are not fully lubricated, dry friction will occur. The heat generated by dry friction in a short period of time is enough to melt the metal, causing damage or even jamming of the parts (piston scuffing, crankshaft pads, etc.), so the matching parts in the engine must be well lubricated. When the lubricating oil flows to the mating part, an oil film will be formed on the friction surface. In order to ensure that the lubricating oil can reach the mating surface smoothly, the engine lubricating oil must have a c...
