Abstract
The present invention relates to crankshaft front-end output structure for internal combustion engine, comprise bent axle, master gear and crank pulley, be characterized in: between described master gear and bent axle, be provided with the first locating stud, the second locating stud is provided with between described master gear and crank pulley, described second locating stud is located at master gear and crank pulley central position, and described master gear is fixedly connected with bent axle by circumferentially uniform several bolts with crank pulley.Bent axle, master gear and crank pulley are fixed together by two locating studs and several bolt by the present invention, form crankshaft front end export structure.The axial force of bolt is changed into the exportable moment of torsion of bent axle by this crankshaft front end export structure, thus substantially increases the output torque of crankshaft front end; In addition, this export structure, compared to existing structure, has the advantages that structure is simple, easy to assembly.
Description
Technical field
The present invention relates to technical field of internal combustion engines, particularly crankshaft front-end output structure for internal combustion engine.
Background technique
In technical field of internal combustion engines, the output of the front end and back end moment of internal-combustion engine completes by bent axle.And how to increase the output torque of bent axle front end and back end, thus increasing combustion engine moment of torsion is the problem that internal-combustion engine industry is forever studied.At present, crankshaft front end exports due to structural limitations, and the connection of master gear adopts the structure of key or interference fit to realize usually, but the connection of key there will be obvious dangerouse cross-section, and interference fit difficulty, cost is high.In addition, above-mentioned Placement limits the output torque of crankshaft front end.
Summary of the invention
The present invention provides a kind of crankshaft front-end output structure for internal combustion engine for solving in known technology the technical problem that exists, and it is simple, easy to assembly that this export structure has structure, and the feature that output torque is large.
The technological scheme that the present invention takes for the technical problem existed in solution known technology is:
Crankshaft front-end output structure for internal combustion engine, comprise bent axle, master gear and crank pulley, it is characterized in that: between described master gear and bent axle, be provided with the first locating stud, the second locating stud is provided with between described master gear and crank pulley, described second locating stud is located at master gear and crank pulley central alignment position, and described master gear is fixedly connected with bent axle by circumferentially uniform several bolts with crank pulley.
The technological scheme that the present invention can also take is:
Described bent axle be provided with the positioning spigot matched between master gear, described positioning spigot is located at both central alignment position.
The advantage that the present invention has and good effect are:
Bent axle, master gear and crank pulley are fixed together by two locating studs and several bolt by the present invention, form crankshaft front end export structure.The axial force of bolt is changed into the exportable moment of torsion of bent axle by this crankshaft front end export structure, thus substantially increases the output torque of crankshaft front end; In addition, this export structure, compared to existing structure, has the advantages that structure is simple, easy to assembly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, bent axle; 1-1, projection; 2, master gear; 2-1, groove; 3, crank pulley; 4, the first locating stud; 5, the second locating stud; 6, bolt.
Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, crankshaft front-end output structure for internal combustion engine, comprise bent axle 1, master gear 2 and crank pulley 3.Be provided with the first locating stud 4 between described master gear and bent axle, be provided with the second locating stud 5 between described master gear and crank pulley, described master gear is fixedly connected with bent axle by circumferentially uniform several bolts 6 with crank pulley.Concrete, bolt, through after the bolt hole on master gear and crank pulley, is locked in the tapped hole on bent axle.Above-mentioned first bearing pin is for ensureing the accuracy of master gear timing position, and this locating stud is located at the non-central location of master gear and bent axle.
In technique scheme: when not hindering bolt to be connected and fixed, in order to the stability of the axial runout precision and connection that ensure crank pulley, the position of described second locating stud is located at master gear and crank pulley central alignment position.In order to ensure that master gear is beated relative to the flank of tooth of crankshaft center, described bent axle be provided with the positioning spigot matched between master gear further, described positioning spigot is located at both central alignment position.Concrete, protruding 1-1 can be set on the end face of bent axle, the corresponding end face of master gear arranges the groove 2-1 matched.
The foregoing is only of the present invention and goodly execute example, be not used for limiting practical range of the present invention.Namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, and all fall into technical scope of the present invention.
