Abstract
The utility model provides a time correction system of an engine. The time correction system of the engine comprises a crankshaft sprocket (1), a first level chain (2), a high-pressure oil pump sprocket (3), a second level chain (4) and a camshaft sprocket (5). Due to the fact that widened design of the crankshaft sprocket and the high-pressure oil pump sprocket is adopted, arrangement space is reserved for replacement of a single row chain transmission system with a double-row chain transmission system, and requirements of a basic type of the engine and the engine after a later stage upgrade are satisfied. The time correction system for the engine is simple in structure, and easy to implement.
Description
Technical field
The utility model relates to engine art, relates in particular to a kind of engine timing system.
Background technique
The function of engine timing system is mainly that the power in engine operation, bent axle transmitted is delivered on camshaft by timing tooth-like belt or chain, to reach, drives valve mechanism opening and closing on time, makes motor be able to continuous work.Consider that chaindriven transmission distance is longer, the characteristics that structure is light, at present increasing diesel timing system adopts the chain transmission.Because the Environmental Conditions of diesel engine is severe, the operating mode complexity.Bearing capacity to timing system requires also more and more higher.
The LD-diesel of 2.0L left and right adopts single-row chain transmission or double strand chain transmission at present.The single-row chain transmission is had relatively high expectations to the bearing capacity of chain, if later stage motor upgrading, the load of chain also can be corresponding honest, need to be redesigned timing system.Directly adopt the double strand chain transmission, although can meet the requirement of later stage motor upgrading, for the basic model of engine design, caused a kind of waste of resource.
The model utility content
The purpose of this utility model has been to provide a kind of single-row chain transmission system that can upgrade to double white silk, to meet motor basic model and later stage upgrading needs simultaneously.
The utility model embodiment provides following technological scheme:
A kind of engine timing system, comprise crankshaft sprocket, one-level chain, high pressure oil pump sprocket wheel, secondary chain and camshaft sprocket, crankshaft sprocket is connected with the hinge wheel of high pressure oil pump sprocket wheel by the one-level chain, the minor sprocket of high pressure oil pump sprocket wheel is connected with camshaft sprocket by the secondary chain, centre of sprocket on described crankshaft sprocket is 20.1-32.1mm apart from the scope of the distance of crankshaft sprocket front-end face, and the scope of the hinge wheel on described high pressure oil pump sprocket wheel and the centre distance of minor sprocket is 23-34mm.
Alternatively, described crankshaft sprocket width is 40mm, and centre of sprocket is apart from crankshaft sprocket front-end face 22.1mm, and described high pressure oil pump sprocket wheel width is 54.1mm, and the centre distance of hinge wheel and minor sprocket is 28.1mm.
Can learn that by technique scheme the utility model beneficial effect is: after the upgrading of motor basic model, without timing system is carried out from new design, Widening Design by crankshaft sprocket and high pressure oil pump sprocket wheel, leave arrangement space for the single-row chain transmission system is replaced by the double strand chain transmission system, can directly change crankshaft sprocket and the high pressure oil pump sprocket wheel that can be complementary with double strand chain.

Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model crankshaft sprocket structural representation.
Fig. 3 is the utility model high pressure oil pump structural representation.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can be in the situation that do similar popularization without prejudice to the utility model intension, so the utility model is not subject to the restriction of following public specific embodiment.
As the description in the above-mentioned background technology, in order to meet the requirement of motor basic model and later stage upgrading simultaneously, reduce development cost.The utility model proposes a kind of timing system, this system is for upgrading to the single-row chain transmission system of double strand chain.
Specific embodiment of the present utility model is as follows:
As shown in Figure 1, it is the structural representation of the engine timing system of a 2.0L diesel engine, in this embodiment, the crankshaft sprocket 1 of timing system is connected with the hinge wheel C of high pressure oil pump sprocket wheel 3 by one-level chain 2, and the minor sprocket D of high pressure oil pump sprocket wheel 3 is connected with camshaft sprocket 5 by secondary chain 4.
As shown in Figure 2, structural representation for the crankshaft sprocket in this embodiment, the scope of the distance of the sprocket wheel A centre distance crankshaft sprocket 1 front-end face B on crankshaft sprocket 1 is 20.1-32.1mm, preferably crankshaft sprocket 1 width is 40mm in the present embodiment, sprocket wheel A centre distance crankshaft sprocket 1 front-end face B 22.1mm.And common single-row chain crankshaft sprocket width is 20mm, centre of sprocket is apart from crankshaft sprocket front-end face 10mm.Designed crankshaft sprocket 1 than common centre of sprocket apart from the crankshaft sprocket front-end face apart from increasing 12.1mm.
As shown in Figure 3, structural representation for the high pressure oil pump sprocket wheel in this embodiment, the scope of the hinge wheel C on high pressure oil pump sprocket wheel 3 and the centre distance of minor sprocket D is 23-34mm, and in the present embodiment, preferred high pressure oil pump sprocket wheel 3 width are 54.1mm, and hinge wheel C and minor sprocket D centre distance are 28.1mm.And common single-row chain high pressure oil pump sprocket wheel width is 43.5mm, hinge wheel and minor sprocket centre distance are 22.5mm.Designed high pressure oil pump sprocket wheel increases 5.6mm than common high pressure oil pump sprocket wheel hinge wheel and minor sprocket centre distance.
The utility model carries out Widening Design to crankshaft sprocket 1 and high pressure oil pump sprocket wheel 3, for being replaced by the double strand chain transmission system, the single-row chain transmission system leaves arrangement space, on the one hand, can be used as basic model uses, on the other hand, after to the upgrading of motor basic model, crankshaft sprocket 1 and high pressure oil pump sprocket wheel 3 can be changed to upgrading, change and upgrade to duplex structure, just can meet the bearing capacity demand, avoid timing system is redesigned, reduce development cost, and simple in structure, easy to implement.
Although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model.Any those of ordinary skill in the art, do not breaking away from technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from technical solutions of the utility model, do any simple modification, equivalent variations and modification according to technical spirit of the present utility model to above embodiment, all still belongs in the scope of technical solutions of the utility model protection.
