Problems solved by technology
[0003] The existing engine piston-and-rod mechanism is mainly composed of a piston assembly and a connecting rod. The piston assembly includes a piston, a piston ring, and a piston pin. The piston ring plays a sealing role, including an oil ring and a gas ring. The reciprocating linear motion of the piston is converted into the rotational motion of the crankshaft. During the operation of the engine, the reaction force of the crankshaft to the piston causes the piston to generate alternating stress on the cylinder wall, which wastes energy while reducing the engine speed and reduces the contact between the piston and the cylinder wall. service life

The invention discloses a symmetrical link type engine piston link mechanism, and belongs to the technical field of engine piston links. The symmetrical link type engine piston link mechanism comprises a crankshaft link hinge, a first piston link, a piston, a second piston link, a piston link guide hinge, a piston link guide rod, a crankshaft and a crankshaft link, wherein the piston is arranged in an air cylinder, one end of the first piston link and one end of the second piston link are correspondingly connected with the tail end of the piston guide rod of the piston correspondingly throughpins, the other end of the second piston link is in hole shaft fit with the other end of the piston link guide rod through the crankshaft link hinge, the other end of the second piston link is in holeshaft fit with the other end of the piston link guide rod through the piston link guide hinge, one end of the crankshaft link is in pin connection with to the crankshaft link hinge, and the other endof the crankshaft link is in pin connection with a crankshaft journal of the crankshaft. According to the symmetrical link type engine piston link mechanism, the resultant force applied on the pistonin the operation process of an engine only comprises axial force so that the alternating stress between the piston and the cylinder wall can be eliminated, the friction loss can be reduced, and the service life of the engine can be prolonged.
Description
technical field [0001] The invention belongs to the technical field of engine piston connecting rods, and in particular relates to a symmetrical connecting rod type engine piston connecting rod mechanism. Background technique [0002] In the existing engine technology, the generally used energy conversion mechanism is the crank-link mechanism. The function of the crank-link mechanism is to provide a combustion place, and convert the expansion pressure of the gas generated by the combustion of the fuel on the top of the piston into the rotational speed of the crankshaft. Torque, continuously output power. The specific implementation methods are divided into: changing the pressure of the gas into the torque of the crankshaft; changing the reciprocating motion of the piston into the rotational motion of the crankshaft; converting the force of combustion on the top of the piston into the torque of the crankshaft to output to the working machine Mechanical energy. [0003] The ...
