Abstract
The utility model discloses the box drawbar trailer of a kind of energy-conservation anti-drag type, belong to heavy motor vehicle parts technical field.Its technical scheme is: the box drawbar trailer of a kind of energy-conservation anti-drag type, comprises trailer envelope, it is characterized in that: arrange front lower acceleration backplate in trailer envelope front bottom end; Arrange side skirt in trailer envelope both sides, described side skirt is arranged near the position of trailer envelope afterbody to the umbilicate aerofoil profile cancave cambered surface of trailer envelope; At trailer envelope afterbody, rear spoiler is set.The beneficial effects of the utility model are: 1, structure is simple, and be easy for installation and removal, attractive in appearance, cost is lower, for the box drawbar trailer of different length, can realize general, having very high commonality by changing side skirt length; 2, this box drawbar trailer is compared with conventional trailer, have quality light, resistance, the advantage such as energy-conservation are fallen; 3, pneumatic resistance when conventional trailer is run at high speed is solved excessive, tractor-trailer train excessive oil consumption problem.
Description
Technical field
The utility model relates to heavy motor vehicle parts technical field, particularly the box drawbar trailer of the energy-conservation anti-drag type of one.
Background technology
Along with Vehicle Speed is more and more higher, the windage problem of vehicle seems more important.By inference, when speeds with 90km/h of the artic of a 49t, wherein the energy ezpenditure of 46% is used to overcome pneumatic resistance, and the pneumatic resistance that this means often to reduce by 10% just has the fuel-economizing space of 4%-6%, reducing the reduction of car load windage to complete-vehicle oil consumption thus has important meaning.
In 35 years of past, there is earth-shaking change in global truck design, from the windage of simple improvement tractor truck, to the unit design of the fusion of tractor truck and trailer, the styling design more and more systematization of heavy-duty commercial vehicle, comprises tractor truck, all factors of trailer all brings into and consider within scope of design.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of energy-conservation anti-drag type box drawbar trailer.
The box drawbar trailer of a kind of energy-conservation anti-drag type, comprises trailer envelope 1, wherein, in described trailer envelope 1 front bottom end, front lower acceleration backplate 2 is set, described front lower acceleration backplate 2 is initial from trailer front support leg 3 position, extends to axle front end side by side only, overall in sphenoid shape;
Arrange side skirt 4 in described trailer envelope 1 both sides, described side skirt 4 is arranged near the position of trailer envelope 1 afterbody to the umbilicate aerofoil profile cancave cambered surface of trailer envelope 1;
Arrange rear spoiler 5 at described trailer envelope 1 afterbody, described rear spoiler 5 is positioned at trailer envelope 1 rear end by two, the swash plate formation that left and right is relative, attachment stream is utilized to fall resistance principle, change trailer afterbody flow field structure, reduce afterbody round vortexing, play the effect reducing train windage.
Be provided with link rod between spoiler 5 and described trailer box 1 rear door in the rear, described link rod respectively with described rear spoiler 5 and described trailer box 1 hinged, left and right rear spoiler 5 can with trailer rear door united opening, so that handling goods.
The end face of described rear spoiler 5 is set to and becomes 15 ° of angles with the container end face of described trailer box 1, and the two sides of described rear spoiler 5 are set to and become 15 ° of angles with the container two sides of described trailer box 1 respectively.
The top of described side skirt 4 is connected with the base of described trailer box 1, and the leading portion of described side skirt 4 connects described front lower acceleration backplate 2 rear portion, to reduce flowed energy loss, accelerates air-flow and passes through.
The end that described front lower acceleration backplate 2 is connected with described side skirt 4 is set to opening shape.
Described trailer envelope 1 both sides arrange two relative to door opening 6 respectively.
By test, the beneficial effects of the utility model are:
1, structure is simple, and be easy for installation and removal, attractive in appearance, cost is lower, for the box drawbar trailer of different length, can realize general, having very high commonality by changing side skirt length;
2, this box drawbar trailer is compared with conventional trailer, have quality light, resistance, the advantage such as energy-conservation are fallen;
3, pneumatic resistance when conventional trailer is run at high speed is solved excessive, tractor-trailer train excessive oil consumption problem.
