Abstract
An accessory gear train layout structure at the front end of an automobile engine comprises a crankshaft pulley, an automatic tensioning pulley, an alternating-current generator belt pulley, an idler pulley, a water pump belt pulley, an air conditioner compressor belt pulley and a multi-wedge belt. The gear train only contains single-layer gear trains, and the air conditioner compressor belt pulley and the water pump belt pulley are respectively arranged on the same side of the crankshaft pulley and close to the side of an exhaust manifold; the alternating-current generator belt pulley is arranged above the crankshaft pulley and close to the side of an inlet manifold; the air conditioner compressor belt pulley and the alternating-current generator belt pulley are arranged on the two sides of the crankshaft pulley respectively; the automatic tensioning pulley is located between the crankshaft pulley and the alternating-current generator belt pulley; the idler pulley is located between the alternating-current generator belt pulley and the water pump belt pulley. The accessory gear train layout structure at the front end of the automobile engine meets the requirement of a condition machine through which a finished automobile selects or does not select air conditioner compression, the cost of the engine and the requirement for compact size of the finished machine are also taken into consideration, and a series of waste of manpower and development expenses caused by changes of an accessory gear train system at the front end is greatly reduced.
Description
Technical field
The present invention relates to a kind of engine for automobile, relate in particular a kind of engine for automobile front end accessory gear system.
Background technique
At present air condition compressor is used by large size, and air condition compressor provides refrigeration, heating capacity for whole-vehicle air-conditioner, but in the applicable area of some temperature, is reduction integral vehicle cost, and car load can be cancelled air condition compressor.And motor head accessory wheel system system has two kinds of forms at conventional steps: the belt wheel one of first air condition compressor and other frontal attachments is reinstated a belt and driven, size of engine is compacter like this, but for various reasons, as front end wheel train is arranged the situations such as increase and decrease that reckon without air condition compressor, motor front-end wheel system can not be in car load demand or non-demand air condition compressor while, front end wheel train is unchanged except belt, this will carry out development and Design again to existing motor head accessory wheel system system, will bring so a series of design and develop expense and human resources etc. waste.
It two is that air condition compressor is driven by an independent belt, though considered like this switching of air condition compressor, but motor can increase belt, bracket, Idle wheel and a crank pulley from one deck, become two-layer, this can cause the increase of motor cost and motor and motor large in the change of axial dimension.
Summary of the invention
The object of the present invention is to provide a kind of automobile engine front end accessory gear system, the conveniently while when considering that car load switches air condition compressor more can make motor cost lower, and space is compacter.
For solving the problems of the technologies described above, the present invention takes following technological scheme;
An automobile engine front end accessory gear layout, it comprises crank pulley, automatic tensioner, alternator belt wheel, idle pulley, Water-pump belt wheel, air condition compressor belt wheel and poly Vbelt.It is characterized in that: this train is only containing individual layer train, and described crank pulley is individual layer belt wheel; Accessory wheel system is connected successively crank pulley, automatic tensioner, alternator belt wheel, idle pulley, Water-pump belt wheel, air condition compressor belt wheel and form along crank pulley clockwise direction by poly Vbelt.
Described air condition compressor belt wheel, Water-pump belt wheel are arranged in crank pulley homonymy, near gas exhaust manifold side.
Described alternator belt wheel is arranged in crankshaft pulley top, near intake manifold side.
Described air condition compressor belt wheel and alternator belt wheel are arranged in crank pulley both sides.
Described automatic tensioner is between crank pulley and alternator belt wheel.
Described idle pulley is between alternator belt wheel and Water-pump belt wheel.
The present invention had both met car load and had selected or do not selected air conditioner compressed condition machine, also taken into account the compact requirement of the size of motor cost, complete machine, greatly reduced because changing a series of manpowers that front end accessory gear system brings and the waste of development cost.
Accompanying drawing explanation
Fig. 1 is that front end accessory gear system accessory wheel system of the present invention is arranged schematic diagram;
Fig. 2 is that front end accessory gear system of the present invention removes air condition compressor belt pulley layout schematic diagram;
In figure: crank pulley 1, automatic tensioner 2, alternator belt wheel 3, idle pulley 4, Water-pump belt wheel 5, air condition compressor belt wheel 6, poly Vbelt 7.
Embodiment
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Referring to Fig. 1, a kind of automobile engine front end accessory gear layout, it comprises crank pulley 1, automatic tensioner 2, alternator belt wheel 3, idle pulley 4, Water-pump belt wheel 5 and air condition compressor belt wheel 6, poly Vbelt 7.Described air condition compressor belt wheel 6, Water-pump belt wheel 5 are arranged in crank pulley 1 homonymy, alternator belt wheel 3 is arranged in crankshaft pulley 1 top with Water-pump belt wheel 5, alternator belt wheel 3 is positioned at intake manifold one side, Water-pump belt wheel 5 and air condition compressor belt wheel 6 are positioned at gas exhaust manifold one side, air condition compressor belt wheel 6 is arranged in crankshaft pulley both sides with alternator belt wheel 3, automatic tensioner 2 is between crank pulley 1 and alternator belt wheel 3, and idle pulley 4 is between alternator belt wheel 3 and Water-pump belt wheel 5.Described crank pulley 1 is individual layer belt wheel.It connects crank pulley 1, automatic tensioner 2, alternator belt wheel 3, idle pulley 4, Water-pump belt wheel 5 successively described poly Vbelt 7, and air condition compressor belt wheel 6, forms accessory wheel system, and it is by automatic tensioner 2 tensioning poly Vbelts 7.
Referring to Fig. 2, as remove air condition compressor belt pulley, it connects crank pulley 1, automatic tensioner 2, alternator belt wheel 3, idle pulley 4, Water-pump belt wheel 5 successively described poly Vbelt 7, form accessory wheel system, it is by automatic tensioner 2 tensioning poly Vbelts 7, and it met car load and selected or do not select the condition of air condition compressor also to take into account the compact requirement of the size of motor cost, complete machine.
