Abstract
Novel low windage freight train shell. This car adopts the streamline form excessive at the afterbody, can reduce the windage that receives among the goods vehicle driving process, has reduced the freight train oil consumption, draw that the clearance should be very little between locomotive and the trailer, can reduce the vortex that draws between locomotive and the trailer, reduce the windage, reduce the oil consumption, the trailer afterbody is equipped with the strengthening rib to the intensity and the rigidity of reinforcing trailer afterbody improve stability and security, draw and set up the aluminum alloy spoiler between locomotive and the trailer, aluminum alloy spoiler external coating one deck polyether type TPU, polyether type TPU has tough and ageing -resistant characteristic, is the tasteless environmental protection material of a maturity.
Description
Technical field
The utility model relates to lorry shell, the streamlined truck shell of particularly low oil consumption.
Background technology
The competition in commercial truck market requires that producer constantly reduces oil consumption, improves its transport capacity, reduces lorry windage.Have research to confirm, when high vehicle speeds time, maximum drag sources is in air, and the speed of a motor vehicle is higher, and the air resistance that vehicle is subject to is larger, square being directly proportional of the added value of air resistance and speed of a motor vehicle added value.Experiment shows, when the speed of a motor vehicle is higher than 80KM per hour time, just has the oil consumption of half to be nearly used to overcome air resistance.In the process of moving, the resistance be subject to has skin resistance to truck.Skin resistance, refer to the friction drag of air-flow by producing during vehicle external surface, this resistance is mainly by car body profile, and the parts be arranged on outside car body, as the resistance that back mirror, Door Handle, car light, headstock ornamental trimming etc. cause interference in air flow, this resistance can produce considerable influence to superimposed trailer and the isometric size automobile of city motor bus.
Summary of the invention
Large in order to overcome resistance in existing lorry driving process, cause the deficiency that lorry oil consumption is too much, the utility model provides a kind of novel low windage lorry shell, and this novel low windage lorry shell can effectively reduce resistance suffered in lorry driving process, reduces lorry oil consumption problem.
The utility model solves the technical scheme that its technical matters adopts: novel low windage lorry shell comprises tractor, trailer top cover and trailer afterbody; Tractor profile is arc line shaped; Trailer top cover and horizontal direction parallel; Trailer Tail Shape is streamline contour; Tractor, trailer top cover and trailer afterbody are 1.5-2:1:4-4.5 in horizontal projection length size than row scope; Tractor and trailer spacing are 150-500mm; Trailer afterbody is provided with staggered form reinforced rib.
A kind of prioritization scheme of such scheme is: arrange aluminum alloy spoiler between described tractor and trailer, aluminum alloy spoiler external coating one deck polyether-type TPU.
The beneficial effects of the utility model are, adopt stream line pattern excessive at truck tail, can reduce suffered windage in lorry driving process, reduce lorry oil consumption; Between tractor and trailer, gap should be very little, can reduce the flow-disturbing between tractor and trailer, reduces windage, reduces oil consumption; Trailer afterbody adds reinforced rib, to strengthen intensity and the rigidity of trailer afterbody, improves stability and safety.Aluminum alloy spoiler is set between tractor and trailer, the gap between tractor and trailer can be coordinated, better reduce windage, make lorry moving velocity faster, reduce oil consumption.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
1. tractor, 2. aluminum alloy spoiler, 3. polyether-type TPU layer, 4. trailer top cover, 5 trailer afterbodys.
Detailed description of the invention
In FIG, novel low windage lorry shell comprises tractor 1, trailer top cover 4 and trailer afterbody 5; Tractor 1 profile is arc line shaped; Trailer top cover 4 and horizontal direction parallel; Trailer afterbody 5 profile is streamline contour; Tractor 1, trailer top cover 4 and trailer afterbody 5 are 1.5-2:1:4-4.5 in horizontal projection length size than row scope; Tractor 1 and trailer spacing are 150-500mm; Trailer afterbody 5 is provided with staggered form reinforced rib; One piece of aluminum alloy spoiler 2 is set between described tractor 1 and trailer, described aluminum alloy spoiler 2 external coating one deck polyether-type TPU layer 3.
Fig. 2 is the birds-eye view of Fig. 1.
