Air deflecting structure for cooling air of vehicle transmission case

Abstract

The invention relates to an air deflecting structure for cooling air of a vehicle transmission case. The transmission case is provided with a case body, a cover body and a belt speed changing mechanism, wherein a driving disc set and a driven disc set are arranged on the belt speed changing mechanism; a driving belt is arranged between the driving disc set and the driven disc set; a cooling air inlet is formed in the cover body; an air deflecting hood covers the outer side of the cover body and is at least provided with an air deflecting opening; the air deflecting opening penetrates through the air deflecting hood. The air deflecting structure is characterized in that a current guiding element is convexly arranged near to the air deflecting opening, on the inner side of the air deflecting hood; a covering rib is arranged above the air deflecting opening, on the inner side of the air deflecting hood; the current guiding element and the covering rib form an air guiding opening communicated with the air deflecting opening, on the inner side of the air deflecting hood; a drainage rib corresponding to the current guiding opening is arranged on the inner side of the air deflecting hood; a water draining groove is formed in the lower end of the drainage rib, so that the quantity, entering the transmission case, of water can be effectively reduced, and further the belt speed changing mechanism arranged in the transmission case is enabled to normally work, and the use efficiency of the belt speed changing mechanism of the transmission case can be improved.

Description

Technical field [0001] The present invention relates to a wind guide structure for cooling wind of a vehicle transmission box, in particular to a provision that can prevent external moisture from entering the transmission box, thereby ensuring the normal operation of the belt transmission mechanism provided in the transmission box, and enabling The wind guiding structure of the cooling wind of the vehicle transmission case improves the use efficiency of the belt transmission mechanism of the transmission case. Background technique [0002] Such as figure 1 As shown, the transmission case 1 of the vehicle power unit is equipped with a belt transmission mechanism 2 which is connected to the transmission case 1 for high-speed operation, thereby moving the vehicle forward. [0003] See again figure 1 As shown, in order to avoid the high temperature generated by the high-speed operation of the belt transmission mechanism 2 in the transmission box 1, damage to the belt transmission mecha...
