Description

  The present invention relates to a side part structure of a vehicle.

  Patent Document 1 describes a corner panel provided at a front corner of a vehicle, and a traveling wind that is supported by the corner panel and extends in the vehicle height direction of the vehicle, from the front to the rear of the vehicle. A vehicle front corner structure including a corner vane that forms a traveling wind passage is disclosed.

  With this front corner structure, an air deflector is formed at the front corner of the vehicle. This air deflector can solve the problem that water and mud adhering to the tire are sucked up by the negative pressure generated on the side surface of the cab such as a truck and the vehicle panel and window glass are contaminated. In addition, since the travel air passage is formed at the front corner by the air deflector, an increase in travel resistance due to the provision of the air deflector can be suppressed, and the travel performance of the vehicle can be improved.

0.5 <(D3 / D1) <1 (5)
More preferably,
(D2 / D1) = 1.13 (6)
(D3 / D1) = 0.57 (7)
The following relational expression holds.

  As described above, the side portion structure of the truck 1 according to the present embodiment has the traveling wind passage 24 having a shape that satisfies the relational expressions of the first to third distances D1 to D3 described above, thereby effectively reducing the traveling resistance of the truck 1. Can be reduced. Specifically, referring to the pressure distribution of the traveling wind W in the traveling wind passage 24 of FIGS. 12 and 13, the traveling wind passage 24 is closer to the curvature maximum portion 44 than the other regions in the traveling wind passage 24. The high-pressure part 46 which becomes a high pressure can be formed.

  The high pressure portion 46 acts against the corner vane 20 with a pressing force F that presses the corner vane 20 toward the front of the cab 2 against the wind pressure of the traveling wind W, thereby reducing the traveling resistance of the cab 2 and thus the truck 1 as a whole. As reduced.

  Further, by providing the corner panel 12 with the upper and lower recesses 34 and 36, the corner vane 20 is not excessively separated from the corner panel 12, and the relational expressions (1) to (5) above, and further the above (6). And the driving | running | working wind path 24 which satisfy | fills the relational expression of (7) can be formed. This effectively reduces the running resistance of the truck 1 while reducing the possibility that the corner vane 20 is too far away from the corner panel 12 and the corner vane 20 protrudes too far forward of the truck 1 to reduce the appearance of the truck 1. Can be reduced.

  Further, the maximum curvature portion 44 is provided in the traveling wind passage 24 at a position closer to the outlet edges 34b and 36b than the respective inlet edges 34a and 36a of the upper and lower recesses 34 and 36. Thereby, in the traveling wind passage 24, while shortening the distance between the maximum curvature portion 44 and the outlet edges 34b and 36b, the length of the second distance D is secured as long as possible, and the third distance D is shortened as much as possible. it can. Therefore, the high-pressure part 46 of high pressure can be efficiently formed in the vicinity of the maximum curvature part 44 by the flow restricting effect using the upper and lower recesses 34 and 36.

  Further, the corner panel 12 is formed with upper and lower side recessed portions 34 and 36 that are recessed toward the inside of the vehicle body in the traveling wind passage 24. When viewed from the side, since it is covered with the corner vanes 20 and is difficult to visually recognize, the running resistance of the truck 1 can be effectively reduced while reducing the possibility of impairing the aesthetic appearance of the truck 1. .

  Further, the upper and lower side recessed portions 34 and 36 are provided in the traveling wind passage 24 at a position closer to the outlet portion 30 than the inlet portion 28. As a result, the upper and lower recesses 34 and 36 are positioned on the downstream side of the traveling wind passage 24, and the distance between the most recessed portion 40 that defines the second distance D2 and the outlet end 20b that defines the third distance D3 is increased. Get closer. Thereby, in the traveling wind passage 24, while shortening the distance between the maximum curvature portion 44 and the outlet end 20b, the length of the second distance D can be secured as long as possible, and the third distance D can be shortened as much as possible. Therefore, the high-pressure part 46 of high pressure can be efficiently formed in the vicinity of the maximum curvature part 44 by the flow restricting effect using the upper and lower recesses 34 and 36. Depending on the shape of the corner vane 20, how the corner vane 20 is attached to the track 1, etc., the second distance D <b> 2 may not be defined by the most concave portion 40.

  Further, the entrance edges 34a and 36a of the upper and lower recesses 34 and 36 are formed to be inclined with respect to the vehicle height direction Y. Accordingly, the inlet edges 34a, 36a can be secured longer than when the inlet edges 34a, 36a are formed in parallel to the vehicle height direction Y, so that the upper and lower dents 34, The air volume of the traveling wind W flowing into the engine 36 can be increased. Accordingly, it is possible to effectively increase the pressure of the high-pressure portion 46 using the upper and lower side recessed portions 34 and 36, and to form the high-pressure portion 46 over a wide range, thereby further improving the running resistance of the truck 1. Can be reduced.

  Further, the outer peripheral edge 20h of the corner vane 20 is formed in a shape similar to the shape of the virtual outer peripheral edge 35c of the upper and lower recesses 34 and 36. Thereby, the air volume of the traveling wind W flowing into the traveling wind passage 24 can be increased at the stage of the inlet portion 28 of the traveling wind passage 24, and the high-pressure portion 46 is formed in a wide range. It is possible to intensively increase the air volume of the traveling wind W on the lower side, and thus on the lower side of the upper and lower recesses 34 and 36. Therefore, the pressure of the high-pressure portion 46 can be further effectively increased, and the running resistance of the truck 1 can be further effectively reduced.

  Moreover, even when the corner panel 12 is formed of the upper panel portion 12a and the lower panel portion 12b and the joint groove 12c is formed between the upper and lower panel portions 12a and 12b as in the present embodiment, By providing the upper recessed portion 34 and the lower recessed portion 36 in the panel portion 12a and the lower panel portion 12b, the running resistance of the truck 1 can be effectively reduced. In addition, since the joint groove 12c has a rectifying function in the traveling air passage 24, the traveling resistance of the truck 1 is further reduced.

  The description of one embodiment of the present invention is finished above, but the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the corner panel 12 includes the upper panel portion 12a and the lower panel portion 12b, and the joint groove 12c is formed between the upper and lower panel portions 12a and 12b. An upper recess 34 and a lower recess 36 are formed in the upper and lower panel portions 12a and 12b, respectively. However, the present invention is not limited to this, and it is possible to form three or more recesses formed in the traveling air passage 24 by appropriately adjusting the installation location of the support member 26 and the presence or absence of installation.

  Further, the corner panel 12 may be formed by a panel without the joint groove 12c, or may be formed by another panel in which the upper panel portion 12a and the lower panel portion 12b are separated. Further, the corner panel 12 may be formed integrally with another panel such as the front panel 10. Moreover, the recessed part of the corner panel 12 should just form the one driving | running | working wind channel | path 24 by the at least 1 recessed part. Further, the recessed portion formed in the corner panel 12 is not limited to a curved surface having a constant or substantially constant curvature as shown in FIG. 6, but may be formed from a smooth curved surface having a plurality of curvatures, for example.

  In addition, depending on the shape and arrangement of the corner vane 20, it is possible to realize the traveling air passage 24 that satisfies the above-described relational expression of the first to third distances D1 to D3, but does not have any recesses, that is, The corner panel 12 may not have a recess.

  Moreover, in the said embodiment, although the shape of the virtual outer periphery 35c of the upper side recessed part 34 and the lower side recessed part 36 is formed in the similar shape to the outer peripheral edge 20h of the corner vane 20, it is not limited to this and is similar. The shape or the same shape may be used.

  Moreover, the side part structure of the truck 1 of the above embodiment is not limited to the cab over truck 1 described above, but can be applied to other commercial vehicles and passenger cars.
