Abstract
A reciprocating plunger engine which the distance of the plunger is less than the two times of the crank, is composed of the connecting rod with the eccentric wheel and the crank link, the two-in-one crankshaft connecting rod system with a plunger. The mechanics is to change the distance of the plunger by rotating the setover of the gyration centre and the geometrical center to save energy and increase the torque. The engine can be used to carburetor engine and the diesel engine.
Description
Technical field:
The present invention relates to the knockdown conventional engine of connecting rod and eccentric mechanism, particularly a kind of piston stroke is less than the engine at twice engine of crank length.
Background technique:
Conventional engine adopts connecting rod more at present, in this mechanism, pitman shaft on the crank is columniform optical axis, what be connected with this pitman shaft is an end of the connecting rod of a rigidity, the other end of connecting rod then is connected with piston by wrist pin, this makes connecting rod in running or when static, and piston and pitman shaft distance in the heart remains constant, so cause piston stroke to equal the twice situation of crank length.Thus, when the torque that provides the bent axle that has than big crank length (the torque arm of force) to make motor output at needs increases, must correspondingly increase piston stroke, thereby also can increase volume of cylinder makes fuel consume more, otherwise, shortening piston stroke when volume of cylinder is diminished for reducing fuel consumption, also must corresponding shortening crank length (the torque arm of force), thus the torque of motor output is diminished.
Summary of the invention:
The object of the present invention is to provide a kind of simple in structure, piston stroke is less than the twice of crank length, can under the situation that does not increase piston stroke, increase the length of crank, or under the situation that does not reduce crank length, shorten the conventional engine of piston stroke, thereby make motor accomplish under the situation that does not increase fuel consumption, to increase torque, or under the situation that does not reduce the output torque, reduce the consumption of fuel.
For achieving the above object, the pitman shaft and the gyration center in the eccentric mechanism that in the connecting rod are geometrical center is coaxial, make connecting rod and eccentric mechanism be combined into totally one connecting rod and a piston and be to make the two-in-one crankshaft ﹠ connecting that rotates in the same way synchronously, allow the crank of the connecting rod in this two-in-one crankshaft ﹠ connecting point to the gyration center of (offset distance sensings) and eccentric mechanism and the sensing of the offset distance between geometrical center setting point-blank, both are put in opposite directions, do in the synchronous rotation in the same way with crank by eccentric mechanism, when utilizing offset distance between eccentric gyration center and geometrical center each point rotating on circumference and the change between cylinder centerline realize making the variation of rigidity length of connecting rod, thereby the stroke that control piston moves up and down makes the twice of piston stroke less than crank length.

Embodiment:
For realizing the present invention, the axle journal (6) of bent axle in the connecting rod being made pitman shaft (5) is eccentric bent axle (4), axle journal circle (6) diameter of eccentric journal pitman shaft (5) on this bent axle (4) is greater than spindle nose circle (7) diameter, the position of these two circles is set to incircle (8), in shaping bent axle (4) process, the axle journal center of circle (9) of eccentric journal pitman shaft (5) is placed between the spindle nose center of circle (10) of bent axle (4) and eccentric journal pitman shaft (5), make the point of contact (8) of axle journal circle (6) with the spindle nose circle (7) of eccentric journal pitman shaft (5), the spindle nose heart (10) of eccentric journal pitman shaft (5), the axle journal center of circle (9) of eccentric journal pitman shaft (5) is sequentially arranged on bent axle (4) central line (14) with bent axle (4) axle center (11), in addition, two shaft shoulders (12) on the eccentric journal pitman shaft (5) respectively and leave space (13) between crank (4).By above enforcement, make bent axle (4) become the eccentric bent axle (4) of rod journal (6).
For realizing the present invention, be connected with connecting rod (3) rotationally on the axle journal (6) of the eccentric journal pitman shaft (5) on the bent axle (4), the piston (2) that an end of connecting rod (3) then slides movably by wrist pin (15) in cylinder (1)
When the axle journal of the eccentric journal pitman shaft (5) on the bent axle of the present invention (4) circle (6) be incircle (8) structure shape with spindle nose circle (7), the relationship change of the axle journal circle (6) of crank (4) length, eccentric journal pitman shaft (5), the spindle nose circle (7) of eccentric journal pitman shaft (5) and piston (2) stroke was with such D
1+ D
3-D
2The calculating formula of=S can be explained out flat-out.
In the formula, D
1Twice for crank (4) length
D
2Axle journal circle (6) diameter for eccentric journal pitman shaft (5)
D
3Spindle nose circle (7) diameter for eccentric journal pitman shaft (5)
S is the stroke of piston (2)
Example 1, work as D
1=90mm, D
3=55mm, S=D
1/ 2 o'clock, ask D
2
By the calculating formula cover be: 90+55-D
2=90/2
D
2＝90+55-90/2＝100mm
Example 2, work as D
1=90mm, D
2=80, D
3During=55mm, ask S
Then get S=90+55-80=65mm by calculating formula
Example 3, work as D
1=90mm, D
2=80mm, D
3During=50mm, ask S
Then get S=90+50+80=60mm by calculating formula
Example 4, as S=70mm, D
2=90mm, D
3During=60mm, ask D
1
Then get D by calculating formula
1+ 60-90=70
D
1＝70+90-60＝100mm
By example 1, example 2, example 3, can understand the D on the bent axle of the present invention (4)
2Compare D
3Big more, stroke S is then more little for piston (2); As D
2More little, then piston (2) stroke S is big more; As D
3More little, then S is more little for piston (2) stroke.In addition, from calculate, as can be known, realize the object of the invention, must D
2＞D3 and D
2＜D
1+ D

Work as D
2=D
1+ D
3S=0 then
The present invention can also implement like this: by the axle journal circle (6) of the eccentric journal pitman shaft (5) on the handle (4) and the circle that includes that is set to decentraction of spindle nose circle (7).
By the enforcement of above scheme, can realize the present invention.
The situation of the present invention's running is as follows:
When piston (2) during at top dead center, crank (4) forwards 0 ° of crank center line of circumference (4) and cylinder centerline conllinear to, turn to downwards because of the offset distance of gyration center (10) in the big stomidium of connecting rod (3) and geometrical center (9) this moment, and with the cylinder centerline conllinear, make that the spindle nose heart (10) and the distance between wrist pin (15) of eccentric journal pitman shaft (5) are recently, thereby allow the length of connecting rod (3) shaft be condensed to the shortest (as Fig. 4) at this moment.
When piston by top dead center in lower dead center is divided a word with a hyphen at the end of a line, because the gyration center (10) in the big stomidium of connecting rod (3) and the offset distance of geometrical center (9) from the bottom to top rotation gradually, make the spindle nose heart (10) and the distance between wrist pin (15) of eccentric journal pitman shaft (5) also enlarge gradually, thereby also allow the length of connecting rod (3) shaft extend (as Fig. 5) gradually.
When piston during in lower dead center, crank (4) forwards 180 ° of circumference to, crank center line (14) and cylinder centerline conllinear, because of the gyration center (10) in the big stomidium of connecting rod (3) and the offset distance between geometrical center (9) turns at this moment and with the cylinder centerline conllinear, make that at this moment the length of connecting rod (3) shaft is stretched to maximum at this moment, the distance between the spindle nose heart (10) of eccentric journal pitman shaft (5) and wrist pin (15) then is (as Fig. 6) farthest at this moment.
When piston by lower dead center in the dividing a word with a hyphen at the end of a line of top dead center, gyration center (10) in the big stomidium of rotation lower link (3) of bent axle (4) and the offset distance between geometrical center (9) are also by upwards rotating gradually, make the length of connecting rod (3) shaft shorten gradually, and the spindle nose heart (10) of eccentric journal pitman shaft (5) and the distance between wrist pin (15) also move closer to (as Fig. 7) by the longest.
