Abstract
The utility model relates to an exhaust pipe device of the power system of traffic vehicles. An improved vehicle exhaust pipe primarily comprises a front-section exhaust pipe 10, an adapter ring 20, a gasket 21, and a rear-section exhaust pipe 30. The front-section exhaust pipe and the rear-section exhaust pipe are matched to abut and install, and the adapter ring and the gasket are additionally arranged between the both. By the alteration of the width of the adapter ring, the exhaust gas displacement of the vehicle exhaust pipe is stochastically altered, which enables the vehicle exhaust pipe to generally use on a plurality of vehicles whose displacements are similar. Meanwhile, a spiral rifling is arranged at the inner hole of the rear-section exhaust pipe in order to guide exhaust gas to be easily exhausted, which reduces noise. The utility model simplifies assembly, and enlarges efficiency.
Description
The utility model relates to the exhausting waste gas pipe arrangement of vehicular traffic power system.
Selecting for use of general vehicular traffic waste gas exhaust pipe, depend on this car engine volume and air displacement thereof, so each not isometric engine, all need outlet pipe with the air displacement coupling, could bring into play the optimum efficiency of engine power effectively, when the air displacement of blast duct for vehicle is obviously hanged down, then can't bring into play engine power fully, cause whole horsepower not enough, the volume class interval difference of existing engine that plurality of vehicles adopts is less, 80 liters for example, 90 liters, the locomotive of 100 liters, about therebetween only have ten, the difference of 20 liter air displacemenies, if still use and the waste gas exhaust pipe that conforms to separately, then owing to the reason in the parts manufacturing need be made many group moulds, thereby the burden that causes cost to increase.
Vehicular traffic waste gas exhaust pipe commonly used is a single constant fixedly body, adopt this outlet pipe commonly used, the exhaust pipe volume that just differs surely with different vehicle is complementary fully, even user or maintenance person are found this blast duct for vehicle and are had situation about not conforming to its air displacement, also can only adopt the way of changing outlet pipe, have nothing for it, this just causes meaningless waste.Simultaneously; vehicle exhaust outlet pipe commonly used all is that the filling glass fibre is used filtering exhaust in its pipe; any supplementary structure that has exhaust gas routing to discharge is not set in its outlet pipe; thereby waste gas regular meeting accumulates in to form in the outlet pipe and circles round the bump air-flow and produce bigger noise, influences environmental quality.
The purpose of this utility model is at the above-mentioned deficiency of existing vehicular traffic waste gas exhaust pipe, and intending provides a kind of modified model blast duct for vehicle, and it is made of front exhaust pipe, adapter ring, packing ring, back segment outlet pipe.Front exhaust pipe and the butt joint of back segment outlet pipe coupling are installed, add adapter ring and packing ring therebetween, by means of the change of adapter ring width, and the exhausting waste gas amount of randomly changing blast duct for vehicle makes it be common to the outlet pipe of the close several various vehicleses of air displacement.Simultaneously be shaped on the spiral rifling,, and lower the circle round phenomenon of bump of air-flow so that exhaust gas routing discharges smoothly at back segment outlet pipe endoporus place car.Both enlarge the effect of blast duct for vehicle, reduced cost again, reduced noise, improved use value.
Realization of the present utility model is a kind of modified model blast duct for vehicle of design, and it is made of front exhaust pipe, adapter ring, packing ring, back segment outlet pipe;
The rear portion car of front exhaust pipe is shaped on outside thread, and its head end still is original fixed interface.
Anterior car is shaped on internal thread in the pipe of back segment outlet pipe, and the outside thread of internal thread and front exhaust pipe is complementary, and its afterbody still is original tailpipe.
Adapter ring with threaded interior hole, behind each suit one packing ring, spiral shell is solid on the outside thread position of front exhaust pipe on its front/rear end, then the back segment outlet pipe is docked spiral shell Guan County dress with front exhaust pipe.
In design, the width of adapter ring can change, and promptly can increase or shorten its width, so as to changing the exhausting waste gas amount of blast duct for vehicle, makes it be common to the outlet pipe of the close several various vehicleses of air displacement.
Simultaneously, car is shaped on the spiral rifling at back segment outlet pipe endoporus place, the noise that bump causes so that exhaust gas routing is discharged smoothly and the attenuating air-flow circles round.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model structure is elaborated:
Fig. 1 is the utility model combination back structure sectional view
Fig. 2 is the utility model STRUCTURE DECOMPOSITION stereogram
10-front exhaust pipe 11-outside thread 12-fixed interface
20-adapter ring 21-packing ring 22-threaded interior hole
30-back segment outlet pipe 31-internal thread 32-tailpipe
33-endoporus 34-spiral rifling
During enforcement, see also Fig. 1, Fig. 2, make each assembly of the utility model earlier, the utility model structure is made of front exhaust pipe 10, adapter ring 20, packing ring 21, back segment outlet pipe 30.
The rear portion car of front exhaust pipe 10 is shaped on outside thread 11, and its head end still is original fixed interface 12.
Anterior car is shaped on internal thread 31 in the pipe of back segment outlet pipe 30, and internal thread 31 is complementary with the outside thread 11 of front exhaust pipe 10, and afterbody still is original tailpipe 32.
In the enforcement, can can change the width of adapter ring 20 according to the difference of vehicular traffic engine and air displacement thereof, promptly increase or shorten its width, use the exhausting waste gas amount that changes blast duct for vehicle, so that to the exhausting waste gas amount that should blast duct for vehicle sets, particularly more suitable for the close several various vehicles outlet pipes of vehicle exhaust amount, the air displacement of the vehicular traffic engine of 80 liters, 90 liters, 100 liters for example, the general better effects if of the utility model.Certainly, also can be by design proposal in advance, in implementing to make, can be divided into the wide cut class interval of several adapter rings 20, so as in as installed to planting the conversion demand of car engine volume.
Simultaneously, car is shaped on the spiral rifling at the endoporus place of back segment outlet pipe 30, uses exhaust gas routing and discharges smoothly, is used for lowering waste gas and accumulates in the noise that the air-flow that is caused in the outlet pipe circles round and clashes into and produce.
The utility model has the advantages that:
1, reduced cost, economical and practical. Because the utility model is common to several close cars Blast pipe, thus original many groups mould of making different single constant blast duct for vehicle reduced Tool has been saved manufacturing cost, has increased practical usefulness.
2. it is more convenient, easily assembled that user and maintenance person are changed blast duct for vehicle, only needs The replacing adapter ring gets final product, and has practical value.
3. reduce waste gas and discharged noise, improved environmental quality.
