通常,市场上可买到的汽缸缓冲器有四种型式。其中圆柱式缓冲器最普通;阶梯式缓冲器和圆锥式缓冲器亦应用较广;短笛式缓冲器减速性好,但由于价格较贵,这种缓冲器常常是根据用户要求专门设计。如图1所示,圆锥式缓冲器与圆柱式缓冲器类似,不同的是圆锥式缓冲器的顶头为锥体,锥度通常为0.5°,用于缓冲一、二、三级冲击。而后面的圆柱部分则用于最后的一、二、三级冲击。由于锥度可使间隙逐渐减小,因此该类型缓冲器能消除圆柱式缓冲器初始的高峰压力。
In general, there are four types of cylinder buffers available on the market. Among them, the cylindrical buffer is the most common; the stepped buffer and the conical buffer are also widely used; the Piccolo buffer has good decelerability, but due to the high price, such a buffer is often specially designed according to the user’s requirement. As shown in Figure 1, the cone buffer is similar to a cylindrical buffer except that the cone buffer cone has a taper of typically 0.5 ° to buffer one, two, three levels of impact. The rear cylindrical part is used for the final one, two, three impact. This type of bumper eliminates the initial peak pressure of a cylindrical bumper due to taper that allows the gap to decrease.
