Abstract
The utility model relates to an engine attachment driving chain system which consists of a crank shaft sprocket wheel, a high pressure fuel pump sprocket wheel and an engine oil pump sprocket wheel. The crank shaft sprocket wheel is connected with the high pressure fuel pump sprocket wheel and the engine oil pump sprocket wheel by a chain. An oil pump chain damper component I, an oil pump chain damper component II and an engine oil pump chain tension board are respectively arranged at each corresponding position at the outer side of the chain. The engine attachment driving chain system has the characteristics of simple and compact structure, fulfilling same task while saving a chain and a set of tension mechanism, shortening the axial size of the engine, saving assembly space and being convenient for installing, improving assembling efficiency, etc. The engine attachment driving chain system reduces the manufacturing cost of the engine further and improves the cost performance and the market competition advantage of the engine.
Description
Technical field
The utility model relates to a kind of diesel engine, particularly a kind of engine accessory power rating chain drive-belt system.It is the accessory drive chain system of co-rail diesel engine first-selection.
Background technique
Motor is the heart of automobile, and the organization plan of motor has determined performance, reliability, manufacture cost of motor etc.Wherein, the accessory drive chain system of motor is the important component part of motor, and the organization plan of this system is for aspect important influence such as the reliability of motor, volume, manufacture costs.Usually, the accessory drive chain system of co-rail diesel engine mainly is the oil pump that is used to drive motor, high pressure fuel pump etc.In traditional diesel engine for automobile, the layout scheme of accessory drive chain system is complicated, and the chain drive-belt of fuel pump only drives the sprocket wheel of fuel pump; The sprocket wheel of the chain drive-belt of an oil pump driving machine oil pump.Two chains are sleeved on the crankshaft sprocket simultaneously, and are furnished with corresponding chain guide plate, tensioning plate, each cover of stretcher respectively.Drive fuel pump and oil pump respectively by two chains, cause the layout difficulty of chain big, when the consumption expenses of labour is installed, make the engine structure complexity, the axial dimension of motor is bigger, and manufacture cost is than problems such as height.
The model utility content
The utility model is at above-mentioned problems of the prior art, provide a kind of simple and compact for structure, transmission of power accurately and reliably, save assembly space, reduce manufacture cost, the engine accessory power rating chain drive-belt system of being convenient to install.
The purpose of this utility model realizes by the following technical solutions:
Form by crankshaft sprocket, high pressure fuel pump sprocket and oil pump sprocket wheel, its described crankshaft sprocket links to each other with high pressure fuel pump sprocket, oil pump sprocket wheel by a chain, and oil pump chain damper assembly I, oil pump chain damper assembly II and oil pump chain tension plate are located at corresponding separately position, the chain outside respectively.
The utility model has the advantages of as follows:
The utility model compared with prior art owing to adopt a chain, a cover tensioning mechanism, drives the technical measures of high pressure fuel pump and oil pump simultaneously, makes the characteristics simple and compact for structure that the utlity model has.Omit a chain and one the cover tensioning mechanism finish same task, shorten the axial dimension of motor, saved assembly space, be convenient to install and improve efficiency of assembling, and then reduced the manufacture cost of motor, improved motor cost performance and market competition advantage.
