Description of the invention (I) «[Detailed description of the invention] [Technical scope of the invention] The present invention relates to a type of locomotive Improvement of air filter used. [Known technology] In the past, the engine, the transmission box with a v-belt transmission built-in, and one or two rear wheels installed at the rear of the transmission box were used for the speed locomotive. The power unit formed by the integration is implemented by cooling the V-f transmission to improve the durability of the V-belt for power transmission. Examples of the cooling method of the V-belt transmission device include a method of reducing the temperature of the atmosphere in the transmission box by stirring the air in the transmission box of the V-belt for power transmission, and introducing outside air into the transmission box. Method to reduce the temperature of the atmosphere in the transmission box. As the latter type of outside air introduction type cooling device, specifically, there is a device of the type described in Japanese Patent Application Laid-Open No. 60-185632. The cooling device is integrally provided with a cooling fan on the drive shaft side pulley of the V-belt transmission device, and an opening is provided at a position opposite to the fan in the transmission box, and external air is introduced into the transmission box through the opening. Constructor. [Problems to be Solved by the Invention] However, the conventional cooling device described above has the following disadvantages. That is, the former stirring-type cooling device is configured to stir the air in the transmission box and reduce the surrounding temperature, so there is a transmission box that can be hermetically sealed without external dust invading. The advantage of worry, but also Have the problem of low cooling capacity _4__ This paper size is applicable to the Chinese National Standard (CNS) Λ4 specification (210X 297 male H ~~ (Please read the precautions on the back before filling this page) Order S.

Description of the Invention (A) There is a clean room for the engine and a clean room for the cooling of the V-belt, so it is not necessary to set up a special air filter for cooling the V-belt. Sex. Moreover, the V-belt cooling chamber of the air cleaner for a locomotive according to the present invention has a V-belt cooling chamber disposed at least partially along the engine chamber and being disposed on the aforementioned engine chamber. Around the clean room, the noise of the engine clean room caused by pulsating inhalation of air will be blocked by the aforementioned V-belt cooling clean room which is always attracted by air, which is very effective. Printed for employees' cooperatives (read the precautions on the back first and then fill out this page). The air cleaner for Scooter locomotives related to the present invention is used in the V-belt cooling chamber. The 淸 clean air exhaust port is located at a position higher than the part arranged along the lower side of the engine 淸 clean room on the downstream side of the V-belt cooling clean room, so the V-belt cooling air flows from the bottom to the top. Through the clean air discharge port, it flows into the transmission box. Therefore, for example, the oil with a heavy specific gravity will flow downward from the bottom to the top, and will fall under the weight without entering the transmission box. Clean room for belt cooling It is used as a filter means of higher net efficiency Qing wet elements, the better to achieve the effect. In addition, because the wet-type element used as a filtering means can be used in the V-belt cooling chamber, the filtering means for the engine-cleaning chamber and the V-belt cooling chamber can be used in common. For the advantage, there is an effect that the user is not forced to perform the troublesome operation of periodically replacing components and the like.
