しかしながら、従来の径方向巻込防止部材７では、ラジエータ２を通過して温風となった空気がラジエータ２の前面に回り込むのを確実に防止することが困難であるという問題があった。
本発明者は、かかる従来の問題を解決すべく鋭意研究した結果、図７に示すように、エンジンファン５の羽根部材８が上方から下方に向けて通過する側の間隙部からの回り込みが、反対側の間隙部からの回り込みに比較して大幅に大きいことを見出した。なお、図７では、エンジンファン５の羽根部材８が左回転しており、図の左側の間隙部からの回り込みが大きくなる。 However, the conventional radial wrapping prevention member 7 has a problem that it is difficult to reliably prevent air that has passed through the radiator 2 and has become warm air from flowing into the front surface of the radiator 2.
As a result of earnest research to solve such a conventional problem, the present inventor, as shown in FIG. 7, wraparound from the gap portion on the side through which the blade member 8 of the engine fan 5 passes from the upper side to the lower side, It was found that it was significantly larger than the wraparound from the opposite gap. In FIG. 7, the blade member 8 of the engine fan 5 rotates counterclockwise, and the wraparound from the gap portion on the left side of the figure increases.

本発明は、かかる知見に基づいてなされたもので、ラジエータを通過して温風となった空気がラジエータの前面に回り込むのを従来より大幅に低減することができるラジエータ温風巻込防止構造を提供することを目的とする。   The present invention has been made based on such knowledge, and provides a structure for preventing the hot air from entraining a radiator that can significantly reduce the air that has passed through the radiator and has become hot air from flowing into the front surface of the radiator. The purpose is to do.

As shown in FIGS. 1 and 2, a radiator 13 is disposed on the lower frame 12 of the cab floor panel 11. An intercooler 15 is disposed in front of the radiator 13. An engine 17 is disposed behind the radiator 13. An engine fan 19 that is rotationally driven by the engine 17 is disposed between the engine 17 and the radiator 13. A fan shroud 21 is disposed on the front side of the engine fan 19 so as to cover the engine fan 19.

そして、ラジエータ１３の側面とキャブフロアパネル１１との間の間隙部には、ラジエータ１３を通過して温風となった空気がラジエータ１３の前面に回り込むのを防止する径方向巻込防止部材２３が配置されている。この径方向巻込防止部材２３は、ラジエータ１３の側面とキャブフロアパネル１１との間の間隙部を遮蔽するように、エンジンファン１９の径方向に延在して配置されている。そして、ラジエータ１３の両側面に固定されている。   In the gap between the side surface of the radiator 13 and the cab floor panel 11, a radial entrainment preventing member 23 that prevents the air that has passed through the radiator 13 from becoming warm air from flowing around the front surface of the radiator 13. Is arranged. The radial wrap-around preventing member 23 is arranged to extend in the radial direction of the engine fan 19 so as to shield the gap between the side surface of the radiator 13 and the cab floor panel 11. And it is being fixed to the both sides | surfaces of the radiator 13. FIG.

ラジエータ１３の側面とキャブフロアパネル１１との間の間隙部の一方には、エンジンファン１９の前後方向に延在する前後方向巻込防止部材２５が配置されている。この前後方向巻込防止部材２５は、図３に示すように、エンジンファン１９の羽根部材２７が上方から下方に向けて通過する側の間隙部に配置されている。この実施形態では、エンジンファン１９の羽根部材２７が図３において左回転しており、図３の左側の間隙部に配置されている。そして、ラジエータ１３の側部に固定されている。   In one of the gaps between the side surface of the radiator 13 and the cab floor panel 11, a front / rear direction entanglement preventing member 25 extending in the front / rear direction of the engine fan 19 is disposed. As shown in FIG. 3, the front-rear direction entanglement preventing member 25 is disposed in a gap portion on the side where the blade member 27 of the engine fan 19 passes from the upper side to the lower side. In this embodiment, the blade member 27 of the engine fan 19 rotates counterclockwise in FIG. 3 and is disposed in the left gap portion of FIG. And it is being fixed to the side of radiator 13.

前後方向巻込防止部材２５は、図２に示すように、上下に２分割されている。そして、上部部材２９と下部部材３１との間に、ラジエータ１３の前方に配置されるインタークーラ１５のホース部材３３が配置されている。

A hose member 33 of the intercooler 15 disposed in front of the radiator 13 is disposed between the upper member 29 and the lower member 31.
As shown in FIG. 4, on the lower side of the upper member 29, a clip 35 for fixing a harness connected to the water level sensor of the radiator 13 is easily inserted into an insertion hole 37 provided on the side surface of the fan shroud 21. A notch 29a is formed.

また。この切欠部２９ａの反対側には、図５に示すように、ヒーターホース３９との干渉を防止するための切欠部２９ｂが形成されている。
上述したラジエータ温風巻込防止構造では、エンジンファン１９の前方に配置されるラジエータ１３の側面とキャブフロアパネル１１との間の間隙部のエンジンファン１９の羽根部材２７が上方から下方に向けて通過する側の間隙部に、エンジンファン１９の前後方向に延在する前後方向巻込防止部材２５を配置したので、ラジエータ１３を通過して温風となった空気がラジエータ１３の前面に回り込むのを従来より大幅に低減することができる。 Also. On the opposite side of the notch 29a, a notch 29b for preventing interference with the heater hose 39 is formed as shown in FIG.
In the radiator hot air entrainment prevention structure described above, the blade member 27 of the engine fan 19 in the gap between the side surface of the radiator 13 disposed in front of the engine fan 19 and the cab floor panel 11 passes from above to below. Since the front-rear direction entanglement preventing member 25 extending in the front-rear direction of the engine fan 19 is disposed in the gap portion on the side where the air flows, the air that has passed through the radiator 13 and becomes hot air wraps around the front surface of the radiator 13. This can be greatly reduced as compared with the prior art.

また、前後方向巻込防止部材２５を、ラジエータ１３に固定したので、前後方向巻込防止部材２５をラジエータ１３の側面とキャブフロアパネル１１との間の間隙部に容易，確実に固定することができる。
さらに、ラジエータ１３の側面とキャブフロアパネル１１との間の間隙部に、エンジンファン１９の径方向に延在する径方向巻込防止部材２３を配置したので、ラジエータ１３を通過して温風となった空気がラジエータ１３の前面に回り込むのをより確実に低減することができる。 Further, since the front / rear direction wrapping prevention member 25 is fixed to the radiator 13, the front / rear direction wrapping prevention member 25 can be easily and reliably fixed to the gap between the side surface of the radiator 13 and the cab floor panel 11. it can.
Furthermore, since the radial wrap-around preventing member 23 extending in the radial direction of the engine fan 19 is disposed in the gap between the side surface of the radiator 13 and the cab floor panel 11, it passes through the radiator 13 and warm air. It is possible to more reliably reduce the air that has become around the front surface of the radiator 13.

そして、前後方向巻込防止部材２５を上下に２分割し、その間に、ラジエータ１３の前方に配置されるインタークーラ１５のホース部材３３を配置したので、ホース部材３３の配置を容易にするとともに、ホース部材３３を前後方向巻込防止部材２５の一部として有効利用することができる。   And since the hose member 33 of the intercooler 15 arranged in front of the radiator 13 is arranged between the front and rear direction wrapping prevention member 25 in the vertical direction, the arrangement of the hose member 33 is facilitated, The hose member 33 can be effectively used as a part of the front-rear direction winding prevention member 25.
