Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of lubricating fitting of automobile timing chain.
Background technique
In the motor car engine working procedure; Air inlet, compression, acting, four processes of exhaust constantly take place in cylinder; And all will match with the motion state position of piston the opportunity of each step; The up-down of air inlet and exhaust and piston is coordinated each other, and this just must regulate through timing system.Timing system is given camshaft with energy transfer under the drive of engine crankshaft; Make the inlet and outlet door of motor open in due course or close; Guarantee cylinder ability normal suction and exhaust; Make fresh mixed gas or air be able in time get into cylinder, waste gas is able in time remove from inblock cylinder.
Chain drive system is generally all adopted in the transmission in correct time of motor car engine now, and chain-driven can have advantages such as transmitted power height, reliability and wear resistance are high, design type is various, and chain-driven has demonstrated its wide market application prospect day by day.The friction of each kinematic pair is very big in the engine timing chain system, needs the enough lubricated usability and life-spans that could guarantee the timing chain system.The lubricated of conventional engines timing chain all is through drawing a special oil duct from upper end cap or cylinder body; Cylinder cap, outer surface of cylinder block slowly flow on the sprocket wheel that is installed in bent axle in the effect lower edge of gravity; Engagement through sprocket wheel and chain is lubricated chain, and through chain lubricant oil is sent on other part of timing chain system.This traditional mode is very high to the requirement on machining accuracy of oil leab, and needs extra increase by one oil spout bend pipe to come support system work.Simultaneously, owing to consider the relation of oil pressure, can not be too many from the oil that oil outlet releases, and machine oil easy evaporation in process of flowing, the oil level that arrives sprocket wheel like this is insufficient.If the motor storage period is long, lubricant oil evaporates, in case engine start, machine oil needs the long period could arrive sprocket wheel, can cause in a period of time that chain is bringing into operation unlubricatedly like this, makes the aggravation of chain, sprocket wheel and rail friction.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of efficiently while lower cost ground provides lubricated automobile timing chain to the engine timing chain system lubricating fitting.
The purpose of the utility model can realize through following technical proposal: a kind of lubricating fitting of automobile timing chain; Comprise that one is arranged on above-mentioned timing chain one side and can makes the tensioning rail of timing chain tensioning also can make tensioning rail be resisted against the actuator on the above-mentioned timing chain with being supported on the tensioning rail; It is characterized in that; On actuator, offer the nozzle opening of working oil path in the connection actuator; Actuator contact offer on the tensioning rail in the apical grafting place on the tensioning rail outside one can lubricate above-mentioned timing chain oil through, above-mentioned nozzle opening is positioned at actuator one side and is right against above-mentioned oil through.
Above-mentioned actuator is the timing chain hydraulic tensioner of automobile, and working oil path is the lubricant oil oil circuit that hydraulic tensioner produces oil pressure.The lubricating fitting of this automobile timing chain changes the lubricating structure of traditional timing chain; Make the required lubricant oil of timing chain assembly need from cylinder block and head, not increase oil duct especially; But directly on the timing chain hydraulic tensioner, offer nozzle opening; Extreme pressure lubricant in the working oil path is sprayed by this nozzle opening, is ejected on the timing chain through oil through timing chain is lubricated.At engine start in a flash, hydraulic tensioner just can be lubricated chain in oil spout, prevents to guarantee that timing chain all has sufficient lubricating at any time.When engine stop working, the hydraulic tensioner oil spout stops.
In the lubricating fitting of above-mentioned automobile timing chain, the curved shape of described tensioning rail, an end of tensioning rail is hinged on the housing of motor, and the other end is resisted against on the above-mentioned timing chain described tensioning rail through the support of above-mentioned actuator.One end of tensioning rail is hinged on the motor body through a bearing pin, and tensioning rail can be swung the rate of tension of adjustment tensioning rail to timing chain on bearing pin under the support force effect of actuator.Because the oil through of the lubricating fitting of this automobile timing chain is arranged on actuator and contacts on the tensioning rail in the outside, the apical grafting place on the tensioning rail; Therefore the oil through of tensioning rail can have been avoided the force bearing point of chain, bearing pin and actuator; Guarantee that tensioning rail has enough strength characters, prevent tensioning rail because stressed excessive generation is out of shape even is fractureed.
In the lubricating fitting of above-mentioned automobile timing chain, described oil through runs through above-mentioned tensioning rail both sides of the edge, and the outlet of this oil through faces above-mentioned timing chain.
In the lubricating fitting of above-mentioned automobile timing chain, offer attachment hole on the described actuator, this actuator passes on the housing that above-mentioned attachment hole is fixed in motor through a bolt.
In the lubricating fitting of above-mentioned automobile timing chain, the filler opening of described nozzle opening is connected with the interior working oil path of above-mentioned actuator, and the oil outlet of this nozzle opening is communicated with above-mentioned oil through through above-mentioned attachment hole.
In the lubricating fitting of above-mentioned automobile timing chain, the diameter of described nozzle opening outlet end is less than the diameter of above-mentioned oil through oil inlet end.Nozzle opening than minor diameter forms higher oil pressure easily, and the machine oil of ejection can be arrived on the timing chain.Because the diameter of oil through is relatively large, require lowlyer with the quality of fit of the nozzle opening of actuator, so the requirement on machining accuracy of the two is low, especially directly molding and forming of the oil through of tensioning rail need not to reprocess, and has so just practiced thrift the cost of motor.
Compared with prior art, the lubricating fitting of this automobile timing chain has the following advantages:
1, the lubricating fitting of this automobile timing chain just increases by a nozzle opening on the stretcher that has the timing chain hydraulic tensioner now, and direct molding and forming one oil through on tensioning rail improves simply simultaneously, is fit to extensively promote the use.This lubricating fitting can guarantee that not only the engine timing chain has enough lubricating; And need not process independently oil duct fuel feeding, and reduced the cylinder body process step, also saved the oil spout bend pipe simultaneously; No longer need additional parts to support the timing chain lubrication system, improve the efficiency of assembling of complete machine.
2, the force bearing point of chain, bearing pin and actuator has been avoided in the setting of oil through on the tensioning rail, so can guarantee that tensioning rail has enough strength characters.
3, the lubricating fitting of this automobile timing chain has simple, the advantages such as cost of production is low, good reliability of processing.
