Abstract
The utility model provides an automobile engine variable valve governing system in right time, this system configuration of in engine cylinder block lateral part, its technical essential is: engine variable valve governing system in right time is admitting air in first assembly respectively of cylinder body including setting up, what exhaust cam shaft was last admits air, exhaust VVT sprocket, the setting is in the assembly of cylinder body lower half at the epaxial sprocket in right time of song, admit air, exhaust VVT control valve, be used for admitting air in step, exhaust VVT sprocket, right time the sprocket timing chain, admit air, be equipped with respectively on the cylinder body between exhaust VVT sprocket and the right time sprocket and be used for that spacing timing chain's move rail assembly and orbit determination assembly, admit air, cylinder body top between the exhaust VVT sprocket is equipped with the guide rail assembly, it is equipped with the tensioning ware to move rail assembly bottom. Fundamentally has solved the problem that the current assembling process of engine timing system is loaded down with trivial details, the fault rate is high, the energy consumption is high.
Description
Technical field
The utility model belongs to motor car engine and manufactures field, specifically a kind of motor car engine Variable Valve Time regulating system.
Background technique
Along with the update of automobile product, automobile production enterprise, in constantly competing, constantly accelerates the exploitation of car load product.From the configuration design of car load, material and hardware support kit equipment improve input and also strengthen accordingly, above improvement all will be able to have an impact to the performance of Motor Vehicle and travelling comfort, but the heart-motor of automobile, the most vital for performance, no matter should measure from the supply of material, the aspect such as price and Performance Match, all directly can affect the performance index of vehicle newly developed.As a rule, camshaft assembles sprocket wheel, built-up crankshaft timing sprocket on bent axle, by timing chain camshaft sprocket is connected with crankshaft timing sprocket and carries out work, and chain there is timing marks, corresponding with the timing marks of cam shaft timing chain wheel and crankshaft timing sprocket, assembly process is complicated, assemble incorrect by the timing system of the whole motor of impact, affect the performance of motor, and Variable Valve Time regulating system can regulate valve to arrive best aperture as required at any time, plays the effect of fuel-economizing.
Summary of the invention
The object of model utility is to provide a kind of motor car engine Variable Valve Time regulating system, fundamentally solves the problem that available engine timing system assembly process is loaded down with trivial details, rate of fault is high, energy consumption is high.
For achieving the above object, the utility model provides following technological scheme: this motor car engine Variable Valve Time regulating system, this Operation system setting is at engine cylinder-body sidepiece, its technological points is: described engine variable-valve timing regulating system comprise be arranged on the cylinder body first half be assemblied in air inlet respectively, air inlet on exhaust cam shaft, exhaust VVT sprocket wheel, be arranged on the timing sprocket be assemblied on bent axle of cylinder body Lower Half, air inlet, exhaust VVT control valve, for synchronous air inlet, exhaust VVT sprocket wheel, the timing chain of timing sprocket, air inlet, cylinder body between exhaust VVT sprocket wheel and timing sprocket is respectively equipped with the dynamic rail assembly for spacing timing chain and orbit determination assembly, air inlet, cylinder body top between exhaust VVT sprocket wheel is provided with upper rail assembly, stretcher is provided with bottom dynamic rail assembly.
The beneficial effects of the utility model: timing chain and inlet and outlet VVT, crankshaft timing sprocket are without the need to there being timing marks, air inlet, exhaust VVT sprocket wheel only need by bolts assemblies on air inlet, exhaust cam shaft, without the need to adopting key to locate, structure is simple, fast easy to assembly.The direction of upper rail assembly and the spacing timing chain of orbit determination assembly, prevents timing chain trembling at work, and dynamic rail assembly and the tensioning degree of the common adjusting chain of hydraulic tensioner, prevent chain lax.Without the need to timing marks on chain, be easier to assembling.Side assembling hydraulic tensioner, can the degree of tightness of adjusting chain as required, without the need to carrying out timing assembling and can reaching the object of fuel-economizing.Have employed the two VVT of inlet and outlet, valve opening can be regulated as requested at any time, the improvement of engine consumption reduction, power performance is all improved a lot.
