New Description: [New Technology Field] This creation belongs to the cooling technology of a crankcase of a motor vehicle. Specifically, it refers to a crankcase cover cooling device that can quickly cool down to improve its cooling and lubrication effects. Extend its service life. [Prior Art] According to the crankcase of the two-wheeled motor vehicle, it is used to protect the transmission components such as the crankshaft. Since the crankcase is provided with a high-speed running transmission such as a crankshaft, it is necessary to provide lubrication between the transmission components. The bearing structure of the crankcase of the locomotive is formed by a shaft hole formed on the crankcase cover from the outside to the inside, and the support end of the transmission shaft passes through the shaft hole. For the purpose of lubrication, it is as shown in the first figure. The crankcase cover has a return passage (15) connected to the shaft hole (11) of the transmission shaft, and the oil return passage (15) is convex, so that the oil return passage (15) has a An oil inlet hole (151) and an oil outlet hole (152), wherein the oil outlet hole (152) corresponds to the wall surface of the shaft hole (11), and the oil inlet hole (151) corresponds to the inside of the crankcase for guiding the crankcase Lubricating oil to provide lubrication and hydrazine. Since the lubricating oil is from the closed crankcase, it is only lubricated by lubricating oil, and the cooling effect is extremely limited. At the same time, high temperature is generated under high-speed operation, and the temperature inside the crankcase is gradually increased, and the temperature is high. Not only will the lubrication effect of the lubricating oil be lowered, but the transmission parts and the oil seals are easily damaged, and oil leakage and the like are caused, so that it is necessary to effectively lower the temperature during operation. The reason is that this creator is concerned with the cooling problems faced by the crankcase M318065 cover of the above-mentioned motor vehicle crankcase, and the manufacturing experience: 5, A. by years of research and development, and finally become 4 Γ Γ 道After continuous efforts, research and trials have problems with the cooling effect of the curved sleeves. #克[New content] Dreams are based on soil (4), and the main system is to provide a crankcase cover cooling device. The camera can quickly cool down, and extend it to make a ride. Avoid the damage of 4 seals and transmission parts (4) The main (4) under the wire (4) technical section, to achieve the purpose and effectiveness of the creation: it includes: 兮二ΐ, the lid of the box - it has - for the crankcase transmission A shaft hole is arranged in the shaft, and an oil guiding passage is formed on the crankshaft phase, and the oil guiding passage has an exposed oil inlet hole and an oil outlet hole connecting the shaft hole, and the other is Forming an oil flow passage 'the oil returning prop has an exposed oil hole and an oil inlet hole communicating with the inside of the crankcase; - a heat dissipating unit having a diverging element for rapidly volatilizing a heat source, the heat dissipating element The oil inlet hole and the oil outlet hole having the internal flow passage are connected to the oil return hole of the crankcase cover, and the oil outlet hole of the jade member is connected to the oil guide passage of the crankcase cover; Through the specific realization of the above-mentioned technical means, the heat element allows the Bencun to continuously circulate between the crankcase cover, the shaft hole and the heat dissipation unit, and the household can borrow and use the heat dissipation unit to rapidly reduce the temperature of the oil. Achieve the purpose of speed, and can improve its lubrication effect, Step song vehicles effectively extend the service life of the transmission components of paper, it can increase the added value of products and their competitiveness and economic benefits.
