Description
Technical field
The present invention relates to internal combustion engine parts, a kind of do not increase engine displacement in the case of can increase acting moment, reduce the internal combustion engine power output structure of use cost.
Background technology
Bent axle [bent axle is commonly referred to as power output structure] in currently used internal combustion engine is the bottleneck to utilization of energy.Such as Fig. 1, in figure, the length of A, B 2 determines the moment length of this internal combustion engine acting, also determines the size of cylinder bore, and the degree of depth of cylinder simultaneously.If strengthening the length of A, B 2, so cylinder diameter of cylinder also to strengthen, guarantee connecting rod is in operation and does not collides with cylinder wall, also to deepen with the seasonal epidemic pathogens degree of depth, guarantee compression ratio is in the reasonable scope, thus causing engine displacement to strengthen the most therewith, influence each other between they threes mutually restriction, and has inevitable cause effect relation.
Existing internal combustion engine power output structure all uses bent axle, and cylinder arrangement can only be along crankshaft length direction linear array, if acting moment to be increased, in the case of not increasing auxiliary device [turbo charging installation], can only increase engine displacement.
Summary of the invention
It is an object of the invention to provide a kind of do not increase engine displacement in the case of can increase acting moment, reduce use cost internal combustion engine power output structure.
Employed technical scheme comprise that such for achieving the above object, i.e. a kind of internal combustion engine power output structure, including the power output shaft being arranged in output shaft mounting seat；Wherein:
It is fixed with disk on described power output shaft, 2N curved surface boss A it is symmetrically arranged with on the outer wall of this disk, it is arranged on the curved surface boss B below curved surface boss A, curved surface boss B is consistent with the quantity of curved surface boss A, distance between outer wall and the circle disk center of described curved surface boss A, more than the distance between outer wall and the circle disk center of curved surface boss B, makes to be formed with curved surface track between curved surface boss A and curved surface boss B；
Being fixed with position limiting structure on the outer wall of disk, this position limiting structure and curved surface boss A, curved surface boss B integrally make curved surface track form closed circuit on the outer wall of disk；
The lower section of disk is provided with link supports seat, and this link supports seat is fixed in link supports seat mounting seat；
Being provided with at least connecting rod below the curved surface of each curved surface boss A, the lower end of this connecting rod and the lower end of described power output shaft are through link supports seat, and each connecting rod has the stroke of a low spot lofty perch on the curved surface of corresponding curved surface boss A；
The lower end of described connecting rod is promoted connecting rod to move up by cylinder, the top of connecting rod is tight against on the curved surface of curved surface boss A, connecting rod moves to peak from the minimum point of this connecting rod stroke on the curved surface of curved surface boss A, thus promote whole disk rotational, disk drives power output shaft acting, and its downward pressure is resetted by this connecting rod by the curved sections of the high point on the curved surface of curved surface boss A corresponding to the stroke of next connecting rod to low spot.
Due to the fact that said structure has the advantage, that acting moment, cylinder diameter size, the cause effect relation of certainty is not had between compression ratio three, three parameters can separately design i.e. achieve do not increase engine displacement in the case of can increase acting moment, i.e. increase disk diameter just can realize, also without increasing auxiliary device, reduce use cost.
