Field of the Invention The present invention relates to a locomotive, and more particularly to a locomotive having a belt cooling structure. 7 Pre-Machine Technology In general, the belt in the locomotive gearbox transmits the power generated by the locomotive engine to the reduction gear, thereby providing the power of the rear wheel of the locomotive to drive the locomotive forward. Since the speed of the belt is relatively high, the rotational friction between the belt and the member it contacts will rapidly increase the temperature of the belt itself. Belts are generally made of rubber and other materials. Excessive temperature tends to cause rapid deterioration and deterioration of the belt. This will not only shorten the life but also pose a threat to driving safety. Therefore, most of the locomotive belts have a cooling design to avoid the above problems. Japanese Laid-Open Patent Publication No. Hei No. 23 1 723 discloses a belt cooling structure 10 whose side structure is as shown in FIG. The left side in Figure 1 is oriented towards the front of the locomotive and the right is towards the rear of the car. An intake pipe 11 and a gearbox 12 are located below the foot pedal 14. The intake pipe 11 is mainly composed of an opening portion 1 1 1 , a coil portion 1 1 2 and a connecting portion π 3 . The open end of the opening portion 1 1 1 faces the left side, and the other end thereof is connected to the left end of the serpentine portion 1 1 2 . The opening portion 1 1 1 is fixed by a bracket 15 . The right end of the coil portion 2 is connected to one end of the connecting portion 1 1 3 , and the other end of the connecting portion 1 1 3 is connected to the gearbox 12 for introducing air into the shifting In the box 12, the belt in the gearbox 12 is cooled. -6-

In order to clearly show the position between the members, the upper half of Fig. 2 shows the condition that the foot pedal 14 is not covered. The beam 13 extends approximately above the opening portion 1 1 1 and the gearbox 12, and the opening portion 11 1 overlaps the vehicle beam 13 approximately in the vertical direction. The coil portion 112 is bent to connect the opening portion 1 1 1 and the connecting portion 1 1 3 . By utilizing the deformable characteristics of the coil portion 11, the mutual displacement between the members during driving can be absorbed on the one hand, and the spatial arrangement can be easily performed on the one hand to avoid other members. However, due to space constraints, the intake pipe 11 must be disposed in conjunction with the vehicle beam 13 such that the coil portion 11 2 of the intake pipe 1 1 is closer to the gearbox 12, and is generally closer to the locomotive engine. The position will thus reduce its cooling effect. Moreover, since the opening portion 11 1 of the air intake pipe 11 and the vehicle beam 13 are approximately overlapped in the vertical direction, the position of the footboard 14 from the ground must be designed to be high in order to accommodate two at the same time. The size of the person. However, this often causes inconvenience to the rider when getting on and off the locomotive. Technical Description It is an object of the present invention to provide a locomotive having a belt cooling structure with better cooling efficiency, and a better space configuration can be obtained to facilitate the rider to get on and off the locomotive.

The pedals 37 are designed to lean forward toward the front of the vehicle, and the intake pipe 31 and a portion of the beam 33 are located below the pedals 37. Figure 4 shows the lateral structure of some of the members of Figure 3, i.e., similar to the top view, but with the cover and portions of the footrest 37 removed. 3 and 4, it is shown that the vehicle beam 3 3, the opening portion 3 1 1 and a receiving chamber 38 are arranged horizontally and horizontally, and when viewed from the rear of the vehicle, the opening portion 3 1 1 is approximately between the frame beam 3 3 and the containment chamber 38. The connecting portion 3 1 3 is approximately overlapped with the vehicle beam 33 in a vertical direction. In summary, the intake pipe 31 extends upward and slightly outward toward the rear. The accommodating chamber 3 8 is for accommodating the battery 36 or other components, and the opening portion 3 1 1 is fixed by the support frame 39. However, the storage chamber 38 is not limited to housing the battery 36. One of the openings 3 1 1 of the opening portion 3 1 1 is oriented approximately toward the receiving chamber 38, i.e., toward the inside of the vehicle body, to reduce the chance of impurities being sucked in. Since the beam 3 3, the opening portion 3 1 1 and the receiving chamber 38 are horizontally arranged, the space required for vertical orientation can be saved. Therefore, the height of the footrest 3 7 installed on the frame beam 3 3, the opening portion 3 1 1 and the accommodating chamber 38 from the ground can be effectively reduced to facilitate the rider's up and down. Fig. 5 is a cross-sectional view taken along line 1-1 of Fig. 3. The frame beam 3 3, the opening portion 3 1 1 and the receiving chamber 38 are horizontally arranged laterally from the outside to the inside. As mentioned above, the containment chamber 38 is adapted to receive the battery 36 or other components, and the open portion 31 is fixed by the support frame 39. In this design, the 1257972 spectacles--, S/,, human-, 乂, s,,,, (5) require relatively large space in the horizontal direction, so the containment chamber 38 The center may be deviated from the longitudinal center line 40 of the locomotive body according to the situation to remove the space for the opening portion 31 1 and the vehicle beam 33. Figure 6 is a cross-sectional view taken along line 2-2 of Figure 3, the frame 3 3 being approximately positioned directly above the connecting portion 313. Compared with the prior art, the present invention allows the coil portion of the intake pipe 31 to be arranged by the manner in which the intake pipe 31 extends upward and slightly outward toward the rear of the vehicle and the horizontal arrangement of the members. The 3 1 2 can be placed at the front and away from the engine of the locomotive to improve the cooling effect of the belt. Fig. 7 is a schematic view of a locomotive having a belt cooling structure according to the present invention, in which the components of Figs. 3 and 4 are mounted on a locomotive 70. In addition to the main components such as the intake pipe 3 1 , the transmission 3 2 , the frame 3 3 , the engine 35 , the accommodating chamber 38 , the foot pedal 3 7 , and the air filter device 34 , the locomotive 70 still includes a The vehicle body 71, a front wheel 73, a rear wheel 74 and a mat 72. The seat cushion 72 is mounted and covers the rear half of the vehicle body 71. The transmission case 3 2 and the air filter unit 34 are installed below the rear half of the vehicle body 7 1 . The front wheel 73 and the rear wheel 74 are disposed in front of and behind the vehicle body 71. The technical content and technical features of the present invention are disclosed above, but those skilled in the art can still make various substitutions and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the present invention is not limited by the scope of the invention, and the invention is intended to cover various alternatives and modifications.
