One end of each connecting rod 4 is connected with a piston 3, and the other end is connected with an annular bracket 6 which is combined with a crank 5 into one body; one of main connecting rods 7 is fixedly connected with the annular bracket 6, and the others are movably hinged with the annular bracket 6; the arranged position of each connecting rod 4 is corresponding to the arranged mode of the air cylinder 2 on the circumferential surface, and the crank 5 is fixedly connected with the main shaft. In the utility model the volume of the contour of an engine is more compact, a crankshaft is shortened, the inertia force is decrease d, the torsional oscillation is comparatively light, the speed is increased, and the operation is stable.
Description
The utility model relates to a kind of motor, particularly a kind of cylinder swing-lined motor.
Traditional lap siding cylinder engine is that file has several cylinder units on the different cross section of main shaft, utilize connecting rod that the to-and-fro motion of piston is become rotatablely moving of bent axle, but arranging of this cylinder lap siding cause the effective rate of utilization of motor gabarit volume lower on the one hand; On the other hand, many reciprocating mechanisms such as piston, the valve mechanism etc. of this motor, owing to the restriction of this file structure makes crankshaft-link rod longer, if further improve engine speed, the inertial force of reciprocating member is increased, thereby increase the load of parts such as crankshaft bearing and influence the life-span, the proper functioning of valve mechanism also can suffer damage simultaneously, thereby this motor one is that volume is compact greatly and not, the 2nd, and further speed-raising difficulty relatively.
The purpose of this utility model is to overcome above-mentioned defective, and a kind of both compact structures are provided, and can improve the swing-lined cylinder engine of speed again than prior art.
The purpose of this utility model is achieved in that
A kind of swing-lined cylinder engine, comprise engine cylinder-body, main shaft, air distributing device, cylinder and piston thereof, connecting rod, crank, it is characterized in that in cylinder body the cylinder crank connection rod set is by forming at cylinder and the connecting rod by more than two covers arranged on circumferential surface or the covering of the fan perpendicular on the different circumferential surfacies of engine spindle and show several cylinder crank connection rod set; Connecting rod one end and piston link, the other end and one and the loop bracket of crank one link, wherein master connecting rod and loop bracket fixedly link, all the other are movably hinged, the mode that connecting rod is arranged on circumferential surface at the arrangement position on the loop bracket and cylinder is corresponding, and crank and main shaft are fixedly linked.
Another improvement project of the present utility model is that all connecting rods all are movably hinged with loop bracket, also be provided with a unidirectional rotary steering device of forming by sliding sleeve, loop bar therein between a countercylinder, the connecting rod, loop bar is through within the sliding sleeve, one of any being fixed on the cylinder body in sliding sleeve, the loop bar, another is fixed on the loop bracket, and both are slidingly matched.
Angle distributions such as cylinder and connecting rod are on circumferential surface or in its some sector.
The further improvement of doing of the utility model is that to contain the valve train corresponding with number of cylinders in the air distributing device be plunger type valve mechanism.
A plurality of cylinders, crank-connecting rod group on a circumferential surface or circumference covering of the fan, both can have been arranged owing to adopted said structure to make, and can with main shaft concentric a plurality of circumference arranged side by side on several cylinder crank connection rod set are set, thereby make that motor verandah volume is more compact, under equal conditions, motor length is shorter, the also corresponding shortening of bent axle, and inertial force reduces, can obtain balance preferably with inertia couple, thereby torsional vibration makes gently engine running more steady smooth.
Below in conjunction with accompanying drawing 1 to 5 and embodiment the utility model is carried out more careful description.
Fig. 1 arranges schematic representation for the swing-lined cylinder engine cylinder body of establishing four cylinders is arranged on a circumference.
Fig. 2 is the swing-lined motor schematic representation of the single arrangement of Fig. 1.
Fig. 3 is the schematic representation (inferior part of the cylinder block omission) that the cylinder crank-connecting rod group 2 of double swing-lined cylinder engine arranged side by side is arranged vertically.
The cylinder body arranging structure schematic representation of Fig. 4 is arranged with two cylinders for being in the shape of the letter V on a circumference covering of the fan swing-lined cylinder engine.
Fig. 5 is the structural representation of plunger type valve valve.
Embodiment 1:
A kind of swing-lined cylinder engine of single arrangement is (referring to Fig. 1, Fig. 2), in cylinder body 1, with engine spindle 10 is on the circumferential surface at center, be provided with quadruplet cylinder 2 and connecting rod 4 by the angle of circumference quartering, cylinder 2 fixedly links with cylinder body 1, piston 3 in the cylinder 2 is hinged with an end of connecting rod 4, wherein three the other end and the loop bracket 6 of connecting rod 4 are hinged and connected, the respective end of another connecting rod 4 fixedly links as master connecting rod 7 and loop bracket 6, the same with common engine, has unidirectional rotary steering effect, the arrangement position of connecting rod 4 on loop bracket 6 is corresponding with cylinder 2 mode of arranging on circumferential surface, crank 5 promptly was fixed as one with being connected with common engine of main shaft, and 20 is the flywheel that links to each other with motor among Fig. 2.
Embodiment 2:
Described swing-lined cylinder engine (referring to Fig. 3), be on embodiment 1 basis, be provided with a cylinder crank connection rod set 12 more side by side on parallel another circumferential surface arranged side by side on the identical main shaft, promptly on two concentric circumferential surfacies respectively the quartering be provided with quadruplet cylinder 2, connecting rod 4, loop bracket 6 and crank 5, two swing-lined motors that promptly are equivalent among the embodiment 1 are arranged along the main shaft file.
Embodiment 4: the swing-lined cylinder engine that is in the shape of the letter V and is arranged with two cylinders on a circumference covering of the fan.
Different with the foregoing description is that all connecting rods 4 are all hinged with loop bracket 6, other has a sliding sleeve 8 fixedly to link with loop bracket 6, loop bar 9 is connected with cylinder body 1 hinge, loop bar 9 is through within the sleeve pipe 8, the effect of loop bar 9, sleeve pipe 8 is master connecting rods 7 that replacement and loop bracket 6 are fixedly linked, play unidirectional rotary steering effect, advantage is to make each length of piston travel unanimity.
The porthole valve is the important component part in the cylinder air distributing device 11, but the porthole valve in the available engine generally all is the hard sealing of horn mouth formula, and this porthole valve arrangement complexity often needs to adjust the valve clearance, impact load is also bigger, and is unfavorable to improving engine speed.Another improvements of the present utility model are that the horn porthole valve that passes through usefulness in will existing air distributing device 11 changes plunger type valve shown in Figure 5 into and is made up of piston 13, suction port 14, air outlet 15, rocking arm 16, pitman arm shaft 17 and general cammingly distributing valve tappet 18 etc., and improved advantage like this is to make that sealing is more soft to be beneficial to adapt to engine speed and to improve.
The similar prior art lap siding of distribution course of action motor in the foregoing description, and the distribution process of lap siding V-type engine, general those skilled in the art should be able to analogize, only needing to do an accommodation according to concrete structure gets final product, in addition, around the cylinder body upper piston, be provided with cooling jacket 19 as motor.
