Abstract
The utility model discloses a flow guiding structure at the bottom of a wagon box body. Front wheels and rear wheels are arranged at the bottom of the wagon box body. Flow guiding covers which seal the gaps between the front wheels and the rear wheels are arranged between the front wheels and the rear wheels. The flow guiding covers are of solid-body or hollow-body structures with sealed peripheries. According to the flow guiding structure, the phenomenon, caused by side wind, that airflow transversely penetrates the bottom of a wagon can be effectively prevented, therefore, the eddy at the bottom of the wagon can be eliminated to the greatest extent, meanwhile, eddies on the side faces of the wagon are weakened, air resistance generated when the wagon runs at the high speed is reduced, and the pneumatic performance of the wagon is greatly improved.
Description
Technical field
The utility model relates to the technical field of automobile, espespecially a kind of truck compartment bottom flow-guiding structure.
Background technology
When automobile, when level road at the uniform velocity travels, resistance to motion consists of rolling resistance and air resistance.Square being directly proportional of air resistance during running car and the speed of a motor vehicle, therefore, when car speed increases gradually, the proportion of aerodynamic drag in all resistances increases gradually.Research shows: when the speed of a motor vehicle surpasses 70km/h, aerodynamic drag is one of principal element affected automotive performance.For car, goods carrying vehicle is because volume is large, and the air current flow complexity, therefore have larger aerodynamic drag.When the speed of a motor vehicle surpasses 90km/h, the fuel oil consumption of large-scale goods carrying vehicle nearly 65% is for overcoming aerodynamic drag.And, by improving profile, the pneumatic drag coefficient of a large-scale goods carrying vehicle can descend 50%, improve fuel efficiency 25%.
This case contriver is through studying discovery for a long period of time, for the goods carrying vehicle that carries envelope for rear, owing to thering is longer distance between its front-wheel and trailing wheel, therefore when high vehicle speeds, the zone between its front-wheel and trailing wheel will form very complicated turbulent phenomenon, and the turbulent flow of this complexity has increased the resistance of air greatly, and air-flow can cross arbitrarily inside and outside wheel, make the envelope bottom produce airstream eddy current, therefore not only affect the speed of a motor vehicle, consumption of fuel also increases greatly.For this reason, if can solve the vortex phenomenon of Van type Motor Truck bottom and the turbulent problem between front and back wheel, can reduce vapour lock, this case produces therefrom.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of truck compartment bottom flow-guiding structure that reduces the air resistance when running at high speed.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of truck compartment bottom flow-guiding structure, the bottom of this truck compartment has front-wheel and trailing wheel, the streamlined reefer housing that space seals between being provided with front and back wheel between front and rear wheel, this streamlined reefer housing is solid or for hollow body but the structure of border seal.
The front and back dual-side of described streamlined reefer housing is the arc suitable with front and rear wheel the side of close front-wheel or trailing wheel.
After adopting such scheme, installed a streamlined reefer housing additional between the front and back wheel of truck compartment due to the utility model, this streamlined reefer housing can seal the space between front and rear wheel, can stop the wind-induced air-flow of side to cross bottom of car by actv., the eddy current of elimination bottom of car that therefore can maximum program, the eddy current of automobile side has also obtained weakening simultaneously, reduces the air resistance of lorry when running at high speed, and makes the aeroperformance of automobile obtain improvement greatly.
The accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model;
Fig. 2 is structural representation two of the present utility model;
Fig. 3 is the front view of streamlined reefer housing described in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of truck compartment bottom flow-guiding structure, as shown in Figure 1 to Figure 3, is preferred embodiment of the present utility model.The bottom of described truck compartment 1 has front-wheel 2 and trailing wheel 3, is provided with streamlined reefer housing 4 between front and rear wheel, and this streamlined reefer housing 4 be solid or is hollow body but the structure of border seal.Further, the front and back dual-side 41 of this streamlined reefer housing 4 can be the side of the arc suitable with front and rear wheel close front-wheel 2 or trailing wheel 3, thereby the space between front and back wheel is blocked fully.
After having installed this streamlined reefer housing 4 additional, space between front and rear wheel 2,3 can be sealed, can stop the wind-induced air-flow of side to cross bottom of car by actv., the eddy current of elimination bottom of car that therefore can maximum program, the eddy current of automobile side has also obtained weakening simultaneously, reduce the air resistance of lorry when running at high speed, make the aeroperformance of automobile obtain improvement greatly.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, thus variation or the modification in every case according to claim of the present utility model and specification sheets, done, within all should belonging to the scope that the utility model patent contains.
Claims (2)
1. truck compartment bottom flow-guiding structure, it is characterized in that: the bottom of this truck compartment has front-wheel and trailing wheel, the streamlined reefer housing that space seals between being provided with front and back wheel between front and rear wheel, this streamlined reefer housing is solid or is hollow body but the structure of border seal.
2. truck compartment according to claim 1 bottom flow-guiding structure is characterized in that: the front and back dual-side of described streamlined reefer housing is for the arc suitable with front and rear wheel and near the side of front-wheel or trailing wheel.
