Abstract
The utility model relates to a natural gas engine flywheel casing. The whole casing adopts HT250 or ZL104 liquid pressure casting aluminum blanks; the average wall thickness of a natural gas engine flywheel casing chamber is 6mm; a plurality of reinforcing ribs are arranged on the walls on the front surface and the back surface of the chamber; and a spindle rotation speed sensor mounting hole and an idle speed sensor mounting hole are arranged on the natural gas engine flywheel casing chamber. As the average wall thickness of the natural gas engine flywheel casing chamber is 6mm and the strength is ensured by the aid of the reinforcing ribs, compared with an existing flywheel casing, the weight of the natural gas engine flywheel casing is lightened by about 4kg, thereby manufacturing cost is reduced. The spindle rotation speed sensor mounting hole and the idle speed sensor mounting hole are arranged on the natural gas engine flywheel casing chamber to realize rotation speed detection and achieve the purpose of application to a natural gas engine. The natural gas engine flywheel casing can also be used for an electronic injection double-fuel engine, an electric control air supplementing engine and a large-power engine adopting Renault technology.
Description
Technical field
The utility model relates to flywheel shell of engine, especially the natural gas engine flywheel casing.
Background technique
Along with the develop rapidly of World Economics, automobile pollution sharply increases, and has consumed a large amount of petroleum resources, has discharged a large amount of harmful gases, and environment for human survival is caused bigger harm, becomes the primary pollution source of municipal pollution.For addressing this problem, people are seeking to restructure the use of energy always, adopt the approach of the alternative motor fuels of low public hazards.Some big motor corporations develop electric vehicle, alcohols automobile, gas-fueled vehicles in succession in the world.From aspect factors such as technology maturity, Economy, easy popularity, resources, gas-fueled vehicles are better than electric vehicle, alcohols automobile.The development of gas-fueled vehicles helps alleviating the energy-intensive imbalance between supply and demand and prolongs engine life, and natural gas engine has vast market prospect.The natural gas engine flywheel casing is effective part that connects of realizing natural gas engine and speed changer, and by its variation, the natural gas engine of same model can carry the automobile of different model, meets the need of market.
Summary of the invention
The utility model purpose is to provide the flywheel casing that can apply to electrospray duel fuel engine and natural gas engine, simultaneously by architecture advances, lowers the manufacture cost of product.
For this reason, the technical solution of the utility model is: natural gas engine flywheel casing, whole housing adopt HT250 or the liquid die casting aluminium blank of ZL104, and it is characterized in that: the average wall thickness of natural gas engine flywheel casing chamber is 6mm; On the double-edged wall of chamber, be provided with several stiffening ribs; On natural gas engine flywheel casing chamber, be provided with spindle speed sensor mounting hole and idling sensor mounting hole.
Beneficial effect: the average wall thickness of natural gas engine flywheel casing chamber is 6mm, by the stiffening rib proof strength, compares with existing flywheel casing, and average wall thickness reduces 2mm, and product weight reduces about 4kg, thereby has reduced manufacture cost; On natural gas engine flywheel casing chamber, be provided with spindle speed sensor and idling sensor mounting hole, realize that rotating speed detects, and reaches the purpose of using on natural gas engine.The utility model is compared with the freewheel shell, and it is lighter to have weight, rational in infrastructure, antivibration, fatigue resistance height, few, the few cutting of processing surplus capacity, the characteristics that performance is more excellent.The utility model also can be used for electrospray duel fuel engine, electric controlled gas-compensation motor and adopt the high-powered engine of Reynolds technology.
