Abstract
The utility model relates to a crankshaft and connecting rod structure of a C-series motor cycle engine, which comprises a crankshaft and a connecting rod. The crankshaft eccentricity is 27mm, with a permitted error of 1mm; and the center distance between the crank pin hole of the connecting rod and the piston pin hole of the connecting rod is 90.7mm, with a permitted error of 1mm. Therefore, the crankshaft eccentricity becomes larger, the reciprocating stroke of the piston becomes longer, and the compression ratio of the piston becomes larger, so that in the working process of the engine, the burning oil is fully burnt, the oil consumption is reduced, and the reliability of the engine is improved.
Description
Technical field
The utility model relates to a kind of motorcycle engine crankshaft bar linkage structure, relates in particular to a kind of C series motorcycle engine crankshaft bar linkage structure.
Background technique
At present, in the crankshaft rod structure of the C series motorcycle motor on the market, the throw of eccentric of bent axle is less, cause the reciprocating stroke of piston short, the compression ratio of piston is little, and when engine operation, it is insufficient oil inflame to occur, cause the functional reliability of motor to descend the phenomenon that oil consumption is high.
Summary of the invention
The utility model is in order to overcome the deficiencies in the prior art, to provide a kind of oil inflame abundant, reducing the C series motorcycle engine crankshaft bar linkage structure of oil consumption.
Technological scheme
The purpose of this utility model is achieved in that a kind of C series motorcycle engine crankshaft bar linkage structure, comprise bent axle, connecting rod, its special way is: crankshaft eccentric is apart from being 27 ± 1mm, and the bent axle pin-and-hole of connecting rod and the piston pin hole centre distance of connecting rod are 90.7 ± 1mm.
Beneficial effect
Owing to adopted technological scheme described in the utility model: crankshaft eccentric is apart from becoming big, and the reciprocating stroke of piston is elongated, and it is big that the compression ratio of piston becomes, and in engine working process, oil inflame is abundant, has reduced oil consumption, has improved the reliability of motor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the cut-away view of the described C series motorcycle of the utility model embodiment engine crankshaft bar linkage structure.
Embodiment
Described C series motorcycle engine crankshaft bar linkage structure comprises bent axle 1 and connecting rod 2.
With reference to Fig. 1, the center of bent axle 1 11 is 27 ± 1mm with the distance at crank pin center 12, and the bent axle pin-and-hole 21 of connecting rod is crank pin center 12, with piston pin hole 22 centre distance of connecting rod be 90.7 ± 1mm.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.All foundations technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (1)
1. a C series motorcycle engine crankshaft bar linkage structure comprises bent axle, connecting rod, and its special way is: crankshaft eccentric is apart from being 27 ± 1mm, and the bent axle pin-and-hole of connecting rod and the piston pin hole centre distance of connecting rod are 90.7 ± 1mm.
