Abstract
The utility model relates to a novel crank shaft and a piston connecting rod for an engine. The crank shaft and the connecting rod are optimized based on the crank shaft of straight crank arms and the connecting rod of straight arms of the original engine; each crank arm of the crank shaft is formed in an independent way or in a common combination way via a mode that a curve edge or a folding edge or a curve folding edge simultaneously comprises a straight edge, and moreover, the whole crank arms are bent towards one side; and each rod of the piston connecting rod is formed in the independent way or in the common combination way via the mode that the curve edge or the folding edge or the curve folding edge simultaneously comprises the straight edge, and moreover, the whole rods of the connecting rod are bent towards one side. The engine with the application of the design solves the problem of insufficient momentary power during the working of the piston of the original engine at a lowest point.
Description
Technical field: the utility model relates to engine art.
Background technique: since at present the crankweb of available engine bent axle and piston rod be straight-arm type and straight rod type substantially, just because of the defective of this structure, so that when engine operation, the moment of cylinder detonation, piston rod, the crankweb of bent axle at this moment just point-blank, and the thrust direction of piston rod and the moving direction of check of crankshaft are in a vertical angle, this is the maximum drawback that said structure causes, although compole is short when above-mentioned, but still be unfavorable for conversion and the motor smooth operation that power is initial.
Summary of the invention: the purpose of this utility model is to finish by the crankweb that changes the available engine bent axle and the structure of piston rod.Be about to existing straight-arm bent axle and straight-bar connecting rod and change crank arm bent axle or folding arm bent axle and curved arm rod or folding arm connecting rod into, it is specially: 1, crankweb comprises straight flange separately simultaneously by bent limit or flanging or common combination forms, and crankweb integral body is to the bent axle of curving.2, the bar of piston rod comprises straight flange separately simultaneously by bent limit or flanging or common combination forms, and the bar integral body of connecting rod is to the piston rod of curving.By above-mentioned change, original motor, the problem that the cylinder operation starting efficiency is not high will get a promotion, thereby reach the purpose that improves power, energy saving.
Description of drawings: legend shown in the accompanying drawing is described, just all multi-form middle representative forms under the design principle.Fig. 1 is curved crankweb bent axle; Fig. 2 is broken line type crankweb bent axle; Fig. 3 is the curved connecting rod; Fig. 4 is the broken line type connecting rod.
Embodiment: the purpose of this utility model is achieved in that bent axle and the piston rod that the crankweb of Novel engine crankshaft and piston rod is designed to the crankweb that is made of the identical bent limit arm of bending direction or flanging arm.Shown in Figure of description, the thrust that the cylinder detonation produces when engine operation like this by the crankweb of piston rod crankshaft, can be converted to the torsion of bent axle smoothly, thereby improves the working efficiency of motor, and the running of motor also can be more steady simultaneously.
Claims (2)
1. the bent axle of a new work engine is characterized in that: the crankweb of bent axle is by bent limit or flanging or tortuous limit comprises straight flange separately simultaneously or common combination forms, and crankweb integral body is to curving.
2. the piston rod of a new work engine is characterized in that: the bar of piston rod is by bent limit or flanging or tortuous limit comprises straight flange separately simultaneously or common combination forms, and the bar integral body of connecting rod is to curving.
