轮胎是轮式装载机的支承、导向和行走装置,还具有缓和冲击的作用。装载机的生产率与装载能力的发挥,在很大程度上取决于轮胎的正确选择与使用;同时,轮胎的价格约占装载机总成本的15%,使用寿命又很短,因此,正确选用和保养轮胎,是降低装载机作业成本的一个重要因素。一、轮胎的构造目前,装载机用轮胎有斜交、带束斜交和子午线三种。有内胎斜交轮胎由内胎、外胎和垫带组成。内胎是一个封闭橡胶囊,充气后使外胎紧压在轮辋上,并保持弹性作用。外胎(图11-1)主要由胎面、胎侧、帘布层、缓冲层和钢丝胎圈等组成。帘布层3是外胎的
The tire is the support, guide and travel device of the wheel loader and also has the effect of mitigating impact. The productivity of the loader and the ability to load it depend to a large extent on the correct choice and use of the tire; at the same time, the price of the tire accounts for about 15% of the total cost of the loader and the service life is very short. Therefore, the correct selection and use of Maintaining tires is an important factor in reducing the cost of loader operations. First, the tire structure At present, the loader tires are skew, belt bias and meridian three. Tire bias tires consist of inner tubes, tires, and pads. The inner tube is a closed rubber bladder. After inflation, the tire is pressed against the rim and the elasticity is maintained. The tire (Fig. 11-1) is mainly composed of a tread, a sidewall, a ply, a buffer layer, and a wire bead. Ply 3 is for the tire
