Description
Technical field
The utility model relates to engine art, specifically, relates to a kind of engine timing system.
Background technique
At present, most of motors adopt gear or chain to carry out the transmission in correct time, and gear and chain transmission all have its drawback separately: because DENG generally is the camshaft overhead at present; Camshaft and bent axle distance are far away; Single employing gear transmission needs the bigger or a plurality of gears of size, can have backlash between two engaging gears, can produce impact during transmission; Thereby can produce bigger noise, and gear transmission is had relatively high expectations to environment and lubricating condition.Single employing chain transmission mode, chain distortion easy to wear and make chain elongation, thus cause the jumping tooth, even take off chain, cause timing error.
The model utility content
To the problems referred to above; The purpose of the utility model is to provide a kind of engine timing system, adopts gear to add the structure of chain transmission, and this combined type drive mechanism has been brought into play the advantage of transmission separately; And remedied the deficiency of single drive mechanism, effectively carried out the transmission in correct time.
In order to realize the purpose of the utility model, the technological scheme that the utility model adopts is:
A kind of engine timing system; Oil pump gear and crankshaft gear engagement, crankshaft gear and idle gear A engagement, idle gear A and oil feed pump gear engagement, idle gear A and idle gear C engagement, idle gear C and power steering pump gear engagement, idle gear A and vacuum pump gear engagement, idle gear D and exhaust cam shaft gear engagement, idle gear D and admission cam shaft gear engagement; Idle gear D sprocket wheel is overlapping to be installed on the idle gear D, the oil feed pump gear is overlapping is installed on the oil feed pump sprocket wheel, and timing chain is surrounded on the outside of idle gear D sprocket wheel and oil feed pump sprocket wheel.
Said idle gear D sprocket wheel is provided with timing marks A, aligns with the carrier bar of said timing chain.
Said oil feed pump sprocket wheel is provided with timing marks B, and timing marks aligns with the carrier bar of said timing chain.
Said timing chain adopts single bushed chain, and chain pitch is 9.525mm.
Said idle gear D sprocket wheel is provided with timing marks C, and said exhaust cam shaftgear is provided with timing marks D, and timing marks C aligns with timing marks D.
Said idle gear D sprocket wheel is provided with timing marks E, and said intake cam shaftgear is provided with timing marks F, and timing marks E aligns with timing marks F.

Said idle gear A is provided with timing marks I, and said crankshaft gear is provided with timing marks J, and timing marks I aligns with timing marks J.
The beneficial effect of the utility model is:
The utility model adopts gear to add the structure of chain transmission.Gear-driven advantage is the moment transmission, and stability is high, structural stability, the advantage that transmission power is big, efficient is high; The advantage of chain transmission is or not very high to using environmental requirement, can be used on the bigger environment of high temperature, heavy duty, low speed, dust and is fit to the transmission of two between centers far away.This combined type drive mechanism has been brought into play gear or the chain advantage of transmission separately, and has remedied the deficiency of single drive mechanism, effectively carries out the transmission in correct time.
