Description
Technical field
The utility model relates to a kind of engine piston connecting rod group, is exactly that a kind of reciprocating piston chain type connecting rod is without dead point engine piston connecting rod group.
Background technique
In current engine piston connecting rod group, piston pumps while moving up and down and promoting connecting rod swing, thus driving crank rotates.But existing piston connecting rod unit has the following disadvantages: 1, when piston is dynamic walk to top dead center and lower dead center time, all there will be dead point, and existing motor all thoroughly cannot solve the problem at motor dead point.2, easily wear and tear in piston and connecting rod joint, and damage back piston and cannot continue to use, can only change piston, and piston only has and wear and tear with connecting rod joint, so replacing piston can cause the wasting of resources, cost is high.
Model utility content
For solving the problem, the purpose of this utility model is to provide a kind of reciprocating piston chain type connecting rod without dead point engine piston connecting rod group, piston adopts Split type structure, removable parts component is only needed after wearing and tearing, avoid the wasting of resources, the more important thing is the problem that can solve motor dead point, make the effect that energy-conservation increasing is turned round.
The utility model for achieving the above object, be achieved through the following technical solutions: reciprocating piston chain type connecting rod is without dead point engine piston connecting rod group, comprise piston, piston base hollow, below piston, movable sheath is set, first stationary axle is set in movable sheath, the microcephaly of articulated linkage on first stationary axle, the microcephaly side of connecting rod is provided with shifting block, shifting block is offered groove or pin-and-hole, groove or pin-and-hole are positioned at the first stationary axle side, one end of push rod is equipped with in groove or pin-and-hole, hinged second stationary axle of the other end of push rod, second stationary axle is arranged in the inner chamber of piston, movable sheath can move back and forth by axis in inner chamber.
In order to realize the purpose of this utility model further: described periphery, movable sheath upper end offers mating groove, piston lower portion periphery arranges the coordinating block identical with mating groove quantity, and mating groove matches with corresponding coordinating block.The axis of described second stationary axle crosses the medial axis of piston.The top of described piston is provided with air drain.
The utility model has the advantage of: it is combined up and down by piston and movable sheath, can utilize its distinctive shifting block, movable sheath and push rod that connecting rod can be forced to swing at top dead center or lower dead center place, thus can fundamentally eliminate motor dead point, to reduce energy consumption, reduce the loss of piston connecting rod unit and bent axle.Piston and movable sheath are Split type structure, and this split-type structural makes movable sheath directly and cylinder contact, and by cylinder guidance, its heat radiation and lubrication effect better, run more stable, intensity is higher.Piston head seals, and movable sheath is positioned at the inner chamber of piston base, the problem that itself can effectively avoid high-temperature fuel gas to leak between piston and movable sheath, effectively can guarantee engine operating efficiency.Directly be connected with connecting rod by movable sheath, in running, movable sheath bears larger wearing and tearing, thus, change after can conveniently wearing and tearing, reduce the expense of operation maintenance.Owing to there is no direct annexation between piston and movable sheath, therefore, conveniently upgrading is carried out to the piston rod part of available engine.
Accompanying drawing explanation

Reference character: 1 cylinder 2 piston 3 movable sheath 4 connecting rod 5 first stationary axle 6 groove or pin-and-hole 7 push rod 8 second stationary axle 9 coupling shaft 10 mating groove 11 coordinating block 12 air drain 13 inner chamber 14 shifting block 15 bent axle.
Embodiment
Reciprocating piston chain type connecting rod described in the utility model is without dead point engine piston connecting rod group, and as shown in the figure, comprise connecting rod 4 and piston 2, piston 2 lower hollow, arranges movable sheath 3 below piston 2.Movable sheath 3 and piston 2 are all positioned at cylinder 1, arrange the first stationary axle 5 in movable sheath 3.The microcephaly of articulated linkage 4 on first stationary axle 5.The microcephaly side of connecting rod 4 is provided with shifting block 14.Shifting block 14 is offered groove or pin-and-hole 6, groove or pin-and-hole 6 are positioned at the first stationary axle 5 side.Be equipped with one end of push rod 7 in groove or pin-and-hole 6, hinged second stationary axle 8, second stationary axle 8 of the other end of push rod 7 is arranged in the inner chamber 13 of piston 2.Movable sheath 3 can move back and forth by axis in inner chamber 13.Arrange seal ring between cylinder 1 and piston 2, seal ring is arranged in piston 2 external wall of upper portion.Described seal ring is compression ring and oil ring.If shifting block 10 is offered for groove, then groove directly coordinates with push rod 7, if what offer is pin-and-hole, by a bearing pin and push rod 7 hinged.
At the beginning of expansion space stroke, high-temperature fuel gas is to the work done of piston 2 end face, and piston 2 is by push rod 7 pairs of connecting rod 4 side forces.Because the movable sheath 3 little head that is connecting rod 4 provides the fulcrum of swing, therefore, connecting rod 4 can be forced during piston work done to swing to cross dead center position, namely eliminate dead point.Distance change between the first stationary axle 5 caused because of the little head oscillation of connecting rod 4 and the second stationary axle 8, is moved up and down by movable sheath 3 opposing pistons 2 and makes up.
Movable sheath 3 can slide up and down by opposing pistons 2, and piston 2 is coordinated with connecting rod 4 by push rod 7, and connecting rod 4 is coordinated with movable sheath 3 by the first stationary axle 5, after first stationary axle 5 or movable sheath 3 wear and tear, can directly change, cost is lower, and effectively can avoid the waste that causes because changing piston.And because piston 2 adopts split-type structural, its intensity is higher, and radiating effect is better.Piston 2, push rod 7, movable sheath 3 and connecting rod 4 connect and compose chain structure successively.
For the wearing and tearing taken in sail between cover 3 and cylinder 1, facilitate piston to carry out auxiliary guiding to movable sheath 3 simultaneously, described periphery, movable sheath 3 upper end offers mating groove 10, and piston 2 lower, outer perimeter arranges the coordinating block 11 identical with mating groove 10 quantity, and mating groove 10 matches with corresponding coordinating block 11.This structure plays the effect of leading to movable sheath 3, can effectively avoid producing relative rotation between movable sheath 3 and piston 2.
For avoiding the appearance at dead point further, also can by the following technical solutions: the axis of described second stationary axle 8 crosses the medial axis of piston 2, namely, the axis of the second stationary axle 8 and the center line of piston 2 are positioned on same vertical plane, first stationary axle 5 and shifting block 10 lay respectively at the vertical plane both sides at the center line place of crank, thus, can guarantee that the second stationary axle 8 has certain initial angle with the line relative centre line of push rod 7 lower end mid point.When the stressed work done of piston 2 moves down, push rod 7 can produce the component promoting connecting rod 4 and swing, and connecting rod 4 is rotated along the first stationary axle 5, and when avoiding connecting rod 4 to be positioned at upper and lower stop, dead point appears in connecting rod 4.
For making high-temperature fuel gas more concentrate effectively pistons end force, as shown in Figure 1, the top of described piston 2 is provided with air drain 12.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The technology contents of the not detailed description of the utility model is known technology.
