Crankshaft-free hydraulic transmission engine

Abstract

The invention discloses a crankshaft-free hydraulic transmission engine and relates to the field of internal combustion engine engineering. The crankshaft-free hydraulic transmission engine comprisesa cylinder body, and further comprises at least two input parts, a transmission part and a transmission part arranged in the cylinder body, wherein each input part comprises a piston, a cylinder liner, a piston pin, elastic check rings and a pressure plunger, wherein the piston pin is in sliding connection with the piston, and both ends of the piston pin are provided with the elastic check rings mounted in mounting holes of the piston. An output part comprises a power plunger, a sliding shoe and a swash plate flywheel. The transmission part comprises a pressure cylinder arranged in the cylinder body, a power cylinder arranged in the cylinder body and an oil supplementing system arranged in the cylinder body. The crankshaft-free hydraulic transmission engine has the advantages that heat energy is converted into mechanical energy, the structure is compact, the feedback is timely, the transmission is more steady, the industrialization prospect is good, and the application demand is wide;and the scratching to the cylinder liner caused by the movement of the piston pin in the piston is reduced.

Description

technical field [0001] The invention relates to the field of internal combustion engine engineering, in particular to a crankshaftless hydraulic transmission engine. Background technique [0002] An engine is a power device that converts other energy into mechanical energy. In the automotive field, an internal combustion piston engine is widely used as a power output device, which converts combustion heat energy into rotational mechanical energy for output. The traditional engine mainly releases heat energy through fuel combustion, pushes the piston to reciprocate linear motion, converts heat energy into linear motion mechanical power, and then converts the reciprocating linear motion of the piston into continuous rotation of the crankshaft through the connecting rod, so that the reciprocating linear motion mechanical power conversion In order to continuously rotate the mechanical power, one end of the crankshaft is connected with the flywheel, and then the rotating mechanic...
