Description
technical field
The utility model relates to a kind of swashplate engine.
background technique
Present crank-connecting rod four stroke engine, with connecting rod, by changing the to-and-fro motion of piston into bent axle rotatablely move, is effect that the power on piston changes the externally torque of output of bent axle into simultaneously.Near the shortcoming of this motor: motor is ignition point top dead center, gas blow-through power in cylinder is maximum, but piston is minimum at the arm of force of top dead center position, the torque efficiency obtaining is minimum, connecting rod is maximum to the impact of bent axle, now, maximum at each transmission bound fraction pressure, surface friction drag is maximum, and the power of loss is maximum.In addition, the crankshaft-and-connecting-rod of crank-connecting rod motor is complex-shaped, quality and volume are large, and the cylinder doing work during work produces the moment of forward to bent axle, and the cylinder not doing work produces negative moment to bent axle, thereby cause that crankshaft eccentric is large, vibration is strong, and noise is large, and balance is poor, and the manufacturing process of crankshaft-and-connecting-rod is complicated, cost is relatively high.Bent axle is difficult for repairing after being distorted and being out of shape.
summary of the invention
The purpose of this utility model is to provide a kind of swashplate engine, overcomes the shortcoming that engine friction resistance is large, noise is large and balance is poor of traditional crank linkage mechanism.
A swashplate engine, is characterized in that: comprise swash plate, output shaft, piston, steel ball bearing, left and right cylinder block, left and right cylinder head, intake valve, exhaust valve, inlet hole and exhaust port, left, right cylinder block rigidity symmetry links together, each cylinder is arranged centered by output shaft, left, right cylinder head is rigidly attached to respectively a left side, in right cylinder block, in cylinder head, there is inlet hole, exhaust port and intake valve, exhaust valve, intake valve, exhaust valve can the valve in cylinder head falls motion opening and closing inlet hole in hole, exhaust port, piston and swash plate are converted into rotatablely moving of swash plate by steel ball bearing by the transverse movement of piston, 720 ° of each each left sides of cylinder piston of swash plate rotation, twice of right motion, each cylinder intake valve, each switch of exhaust valve once, complete intake stroke, compression stroke, the work cycle of working stroke and four strokes of exhaust stroke.
A kind of swashplate engine, it is characterized in that: cylinder block is to be arranged symmetrically with, piston movement direction is parallel with output shaft, and piston is two symmetrical fit pistons, two of piston in cylinder block is simultaneously in two cylinder block that are arranged symmetrically with, so cylinder number is into twice increase.
Compared with prior art, its advantage is the utility model: swash plate has replaced connecting rod, and structure is simpler; The chemical energy of fuel is converted into the kinetic energy of piston, the transverse reciprocating motion of piston is converted into rotatablely moving of swash plate, by swash plate, drive externally output torque of output shaft rotation, and output shaft is straight, while deforming, easily repair; When a cylinder is in expansion stroke, piston can carry out directly acting to the cylinder being arranged symmetrically with reduces energy loss; Engine friction is little, stable drive, and balance is good, vibrates littlely, and noise is little, and transformation efficiency is higher than available engine; Inclined disc type new work engine valve adopts electronics valve, in automatically controlled mode, drives, so there is no camshaft, rocking arm set etc., makes that engine structure is compact, volume is less.
