Abstract
The utility model relates to a wheel train structure at the front end of gasoline engine, which comprises a belt, a belt wheel for generator, a belt wheel for water pump, a belt wheel for power steering pump, two idler wheels and an automatic tensioner which is used to ensure the invariableness of multi-wedge belt extension or shortening tension. The working surfaces of all the above wheels are arranged in the same plane and the crankshaft belt wheel, the water pump belt, the compressor belt wheel, the No.1 idler wheel, the generator belt wheel, power steering pump belt wheel, the No.2 idler wheel, the water pump belt wheel and the automatic tensioner are surrounded orderly by a belt to realize the connection. The main components of the engine-generator, the water pump, the compressor and the power steering pump are driven by a belt, the working surfaces of all the wheels are in the same plane, the axial dimensions of the crankshaft belt wheel is reduced, so the arrangement of the wheel train is compact, the volume of the engine is reduced so that the operation of the wheel train is more reliable and belt driving efficiency of the engine is improved, also the installation process is more convenient, rapid and accurate.
Description
Technical field:
The utility model belongs to the petrol engine machine technology, is specifically related to the front end train mounting structure of multi cylinder petrol engine.
Background technique:
The layout of available engine front end train, adopt grading type mostly, referring to Fig. 1, it adopts two belt 12A and 12B to realize, article one, belt 12A connects crank pulley 14, Water-pump belt wheel 11 and generator belt wheel 16, and another belt 12B connects crank pulley 14, compressor belt wheel 15 and boost pump belt wheel 13, and their working surface does not in one plane all drive its running work by crank pulley simultaneously.So just need axially doing crank pulley thick especially, both increased the axial dimension of motor, increased the motor total quality, and made motor become huge, be unfavorable for the layout of motor on car load, the development trend of run counter to the motor miniaturization, gently changing most.Increase mounting process and labor intensity simultaneously, thereby increased exploitation and manufacture cost greatly.
Summary of the invention:
The purpose of this utility model is at existing petrol engine front end train the problem that exists to be installed, a kind of petrol engine front end train mounting structure is provided, train is carried out the layout of compact and reasonable, improve the reliability and the motor band transmission efficiency of train wheel operation, make the easier, quick, accurate of mounting process.
In order to realize this purpose, the utility model has adopted following technological scheme:
Petrol engine front end train mounting structure includes belt, generator belt wheel, Water-pump belt wheel, compressor belt wheel, boost pump belt wheel, two idle pulleys and one and is used to guarantee that poly Vbelt elongates or shortens all constant automatic tensioner of tension force.Working surface design of above-mentioned each wheel in a plane, and is walked around crank pulley, compressor belt wheel, No. 1 idle pulley, generator belt wheel, boost pump belt wheel, No. 2 idle pulleys, Water-pump belt wheel and auto-tensionings successively with a belt and taken turns, they are connected.
The utility model is with the primary component of motor---and generator, water pump, compressor and boost pump etc. are with a belt transmission, the working surface of each wheel is in a plane, reduced crank pulley at axial dimension, make the layout compactness of train, the motor volume reduces, thereby makes train wheel operation more reliable.Improved motor band transmission efficiency, also made mounting process easier, quick, accurate simultaneously.
Description of drawings
Fig. 1 is existing petrol engine front end train mounting structure schematic representation
Fig. 2 is the petrol engine front end train mounting structure schematic representation that the utility model proposes
Embodiment:
Referring to Fig. 2, this petrol engine front end train mounting structure includes generator belt wheel 24, Water-pump belt wheel 26, compressor belt wheel 22, boost pump belt wheel 25, two idle pulleys, 27 and belts 28 of an auto-tensioning wheel.The working surface of above-mentioned each wheel is designed in the plane, and belt 28 is walked around crank pulley 21,22, No. 1 idle pulley 23A of compressor belt wheel, generator belt wheel 24,25, No. 2 idle pulley 23B of boost pump belt wheel, Water-pump belt wheel 26 and auto-tensioning wheel 27 successively.
Installation process:
1, crank pulley 21 is installed on the bent axle, and uses bolton;
2, Water-pump belt wheel 26 is installed on the water pump links to each other, and guarantee that it installs reliable, fastening with engine cylinder-body;
3, generator, No. 1 idle pulley 23A, boost pump, auto-tensioning wheel 27 and a compressor that is used to change the belt trend are installed in generator support bracket, and all use corresponding bolts fastening;
4, another No. 2 idle pulley 23B that regulate trend are installed on the motor head carriage, and use bolton;
5, last, with front end train belt 28 from crank pulley 21, after walking around 22, No. 1 idle pulley 23A of compressor belt wheel, generator belt wheel 24,25, No. 2 idle pulley 23B of boost pump belt wheel, Water-pump belt wheel 26 and auto-tensioning wheel 27 successively more by hand, the tension arms lock pin of auto-tensioning wheel 27 is extracted, thus the auto-tensioning of realization belt 28.
Correct and reliable for guaranteeing that train is installed, in rotatable 2 to 3 weeks of engine crankshaft, check whether the relation between belt and each belt wheel reaches the design and installation requirement.
