[detailed description of the invention]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As Figure 1-Figure 5, a kind of closed-type trailer resistance reducing flow guiding of the utility model, comprise the envelope 1 be fixed on closed-type trailer, this closed-type trailer resistance reducing flow guiding also comprises the streamlined reefer housing 2 at antetheca 11 top being fixed on envelope 1, be individually fixed in two side skirts 3 of diapire 12 both sides of envelope 1 and the deflecting plate 4 between two side skirts 3, the middle part of streamlined reefer housing 2 is protruding towards outside, the two ends of side skirt 3 all inwards bend extension and are provided with conduction part 32, deflecting plate 4 comprises the upper arc 41 below the diapire 12 being fixed on envelope 1 and bends the arc lower plate 42 extended to form from the bottom of upper arc 41, the cambered surface of upper arc 41 is towards protruding near the direction of diapire 12, the cambered surface of arc lower plate 42 is protruding towards the direction away from diapire 12.
Thus, the two ends of each side skirt 3 are all provided with curved conduction part 32 towards the inner side of side skirt 3, reduce further the windage of envelope 1 diapire 12 both sides, the deflecting plate 4 be made up of upper arc 41 and arc lower plate 42, reduce further the windage below diapire 12, the streamlined reefer housing 2 that middle part is protruded towards outside reduce further the windage at envelope 1 antetheca top, at streamlined reefer housing 2, under the cooperation of side skirt 3 and deflecting plate 4, greatly reduce the windage that closed-type trailer bears, improve the stability that vehicle travels, decrease fuel consumption, realize fuel-economizing 8%.
In present embodiment, streamlined reefer housing 2 is from its indentation 22 recessed top down, and the notch area of indentation 22 reduces towards the side near antetheca 11 gradually from its side away from antetheca 11.Thus, the windage that envelope 1 antetheca 11 bears more effectively is decreased.
In present embodiment, the radian of conduction part 32 is 30 °.Thus, the better setting of the diapire 12 both sides windage reducing envelope 1 is achieved.
In present embodiment, the outer surface of streamlined reefer housing 2 is arranged with some first drainage troughs 21, and the outer surface of side skirt 3 is arranged with the second drainage trough 31, and the outer surface of deflecting plate 4 is arranged with some 3rd drainage trough 43, first drainage troughs 21 and is parallel to diapire 12.
In present embodiment, side skirt 3 comprises the front valance panel 33 being articulated with diapire 12.Thus, convenient overturn front valance panel 33 upward with anticlockwise direction, and then facilitate staff and pass in and out at the bottom of car and carry out maintenance work.
In present embodiment, side skirt 3 also comprises the rear skirtboard 35 being fixed on front valance panel 33 side and the middle skirtboard 34 be fixed between front valance panel 33 and rear skirtboard 35, and streamlined reefer housing 2, middle skirtboard 34, rear skirtboard 35, deflecting plate 4 are all fixed on 1 envelope 1 by bolt mode.Thus, be convenient to dismounting and this closed-type trailer resistance reducing flow guiding of resetting, reduce maintenance cost.
In present embodiment, the number of the 3rd drainage trough 43 is 4.Thus, the both intensity of favourable enhancing deflecting plate 4, is conducive to again reducing windage.
In present embodiment, streamlined reefer housing 2, side skirt 3, deflecting plate 4 are glass steel material, and thus, compared to the closed-type trailer resistance reducing flow guiding of other material, the closed-type trailer resistance reducing flow guiding of glass steel material has elasticity, and it is stronger that it falls windage performance.
Compared with correlation technique, the beneficial effects of the utility model are, windage is lower, vehicle run stability is higher, fuel consumption is less.
