車輛傳動裝置Vehicle transmission

本新型係關於一種車輛傳動裝置，尤指一種適用於機車之車輛傳動裝置。The present invention relates to a vehicle transmission device, and more particularly to a vehicle transmission device suitable for a locomotive.

動力系統與傳動裝置是機車重要之二部分，前者一般為內燃引擎或馬達，後者則有多種設計如皮帶式之無段變速機構、純齒輪式機構或其它類型。The power system and transmission are two important parts of the locomotive. The former is usually an internal combustion engine or a motor, while the latter has various designs such as a belt-type stepless transmission mechanism, a pure gear type mechanism or the like.

習知技術之機車引擎傳動裝置，其引擎組與傳動組係相互結合在一起，然後再形成一固定組件，一起組立在車架上，前方有一懸吊點固接在車體上，傳動組後方與後輪及後避震器組立在一起，當後輪上下移動時，則整個引擎組與傳動組也跟著進行擺動，因此這種引擎組之引擎本體及傳動組本體所需的空間需要較大，方能容納此相關機構，且其相關零件需要非常繁多及複雜，進而產生相當大之組裝不便性及零件損壞機率提高，此組合方式對於該傳動裝置之方便性、實用性及耐久性均具有相當不利之影響，另外在整車振動及騎乘舒適性方面亦具有非常不利的影響。The locomotive engine transmission device of the prior art, the engine group and the transmission group are combined with each other, and then a fixed assembly is formed, which is assembled on the frame, and a suspension point is fixed on the vehicle body at the front, and the rear of the transmission group Standing together with the rear wheel and the rear shock absorber group, when the rear wheel moves up and down, the entire engine group and the transmission group also follow the swing, so the space required for the engine body and the transmission group body of the engine group needs to be large. In order to accommodate the relevant institutions, and the related parts need to be very complicated and complicated, resulting in considerable assembly inconvenience and increased probability of damage to the parts, the combination has the convenience, practicability and durability of the transmission. It is quite unfavorable, and it also has a very negative impact on vehicle vibration and ride comfort.

習知機車之引擎與傳動裝置之組裝方式，如圖1所示之一機車90整車示意圖，引擎組之曲軸箱與收容傳動組之箱體鎖附在一起，再整體與引擎之汽缸體鎖附連結，最後將引擎單點懸吊在車架，再加上曲軸箱與避震器連接，因此當後輪上下運動時，整個引擎、曲軸箱以及傳動組之箱體伴隨擺動，皆以懸吊點為樞轉點。The assembly mode of the engine and transmission of the locomotive is as shown in Figure 1. The schematic diagram of the locomotive 90 is shown in Figure 1. The crankcase of the engine block is locked with the casing of the accommodating transmission group, and then the cylinder block of the engine is locked. Attached to the link, the engine is suspended from the frame at a single point, and the crankcase is connected to the shock absorber. Therefore, when the rear wheel moves up and down, the entire engine, the crankcase and the gearbox are swung with each other. The lifting point is a pivot point.

在上述組裝方式下，依據一般物理原理，重的物體慣性也大，因此上述習知設計使得當車輛行走時整車穩定性受到極大負面影響，同時也意味騎乘者操控不易，增加安全性的疑慮。此外，若採用上述習知技術，還必須預留引擎與容納傳動組之箱體搖擺之空間，如此一來即喪失其它元件配置之彈性，而且明顯地，搖擺運動也會加快相關裝置之損壞，並非十分理想，尚有改善的空間。In the above assembly mode, according to the general physical principle, the inertia of the heavy object is also large, so the above-mentioned conventional design makes the stability of the whole vehicle greatly negatively affected when the vehicle is walking, and also means that the rider does not easily control and increases the safety. doubt. In addition, if the above-mentioned prior art is adopted, it is necessary to reserve the space for the engine to oscillate with the casing accommodating the transmission group, so that the elasticity of the other component configurations is lost, and obviously, the rocking motion also accelerates the damage of the related device. Not very ideal, there is still room for improvement.
