Description
Technical field
The present invention relates to auto parts machinery field, particularly portable type piston of automobile connecting bar and crankshaft group.
Background technique
Piston rod group is the driving component of motor car engine, and it passes to bent axle the pressure of combustion gas, makes crankshaft rotating outputting power, and piston rod group is mainly made up of piston, piston ring, wrist pin and connecting rod etc.
In traditional wrist pin key seat hole, there is the annular groove that snap ring is installed, be used for preventing that wrist pin from axial motion occurring at work, but this elastic circlip is shorter working life, and easily damage and cause fault, traditional connecting rod is directly connected in bent axle in addition, in the time of work, easily because causing wearing and tearing, strenuous exercise even comes off like this, 201220066873.9 files that are as China Patent No. disclose a kind of new work engine bent axle and piston rod, this crankshaft-and-connecting-rod is the optimization of carrying out on the basis of original engine direct crankweb bent axle and straight-arm connecting rod, 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 entirety is to curving, be used for solving original engine piston in the minimum point work moment problem that is short of power, but still there are the problems referred to above in this bent axle piston rod group.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of portable type piston of automobile connecting bar and crankshaft group, to solve the above-mentioned multinomial defect causing in prior art.
For achieving the above object, the invention provides following technological scheme: portable type piston of automobile connecting bar and crankshaft group, comprise piston, connecting rod, bent axle, described connecting rod one end is connected in piston, the other end is connected in bent axle, described piston is provided with compression ring He Er road compression ring one, on described piston, be also provided with wrist pin, described bent axle one end is connected with bearing, the other end is connected with driving gear and timing sprocket, is also provided with woodruff key on described bent axle, and described wrist pin two ends are provided with jump ring, described bent axle bottom is provided with connecting rod cap, and described connecting rod cap is connected with connecting rod by flange.
Preferably, be also provided with oil ring on described piston, described oil ring is located at two compression ring belows, road.
Preferably, described oil ring is alloy cast iron material.
Preferably, described flange is flat brain type.
Preferably, described connecting rod is that alloyed steel is made.
Preferably, described wrist pin is wholly floating.
Adopt the beneficial effect of above technological scheme to be: simple in structure, easy to use, by being set at wrist pin two ends, jump ring provide protection against wear evenly, wear extent is little, the little axial motion that occurs at work of bending deformation quantity, and this jump ring has good rigidity, can ensure to prevent vibration, can there is again higher working life, connecting rod cap is connected with in the below of bent axle can play certain protection buffer function to connecting rod, can crankshaft-and-connecting-rod be separated by turning on flange simultaneously, be convenient to dismounting dimension, on piston, be also provided with oil ring and can play frizing, cloth oil and auxiliary seal effect, there is better sealing and frizing effect although alloy cast iron cost is slightly high, flat brain type flange can be allowed to condition at engine interior and avoid the nonuniformity of wearing and tearing, fully floating wrist pin has advantages of that bending deformation quantity is little.
Brief description of the drawings
Fig. 1 is the structural representation of portable type piston of automobile connecting bar and crankshaft group of the present invention;
In figure, be labeled as: 1, piston; 2, connecting rod; 3, bent axle; 4, woodruff key; 5, bearing; 6, one compression ring; 7, two road compression rings; 8, oil ring; 9, jump ring; 10, wrist pin; 11, driving gear; 12, timing sprocket; 13, connecting rod cap; 14, flange.
