本届展会上来自国内外的多家平地机生产厂商带来了代表本企业水平的最新产品,从参展的产品看,平地机的设计、结构和工作原理虽没有跳跃式发展,但却有明显进步,表现出如下技术特点和发展趋势。 动力匹配 根据产品样本所标示的技术参数,国外中型以上的平地机操作质量和发动机输出功率的比值比国内的匹配数值大,一般为0.12～0.14,国产平地机高的达到0.12,低的还不足0.1。此比值高的优点是作业有力,特别是在Ⅰ挡作业时最为明显。在发动机选配上,国外知名公司更重视发动机的功率储 A number of manufacturers of grader from home and abroad brought the latest products representing the level of the enterprise at this exhibition. Judging from the products they exhibited, the design, structure and working principle of grader did not have a leap-forward development, but there was obvious Progress, showing the following technical features and trends. Power Matching According to the technical data indicated in the product samples, the ratio of operation mass and engine output power of motor graders outside medium-sized and medium-sized countries is larger than the matching value in China, generally from 0.12 to 0.14, and the height of domestic graders reaches 0.12 and the low is insufficient 0.1. The advantage of this ratio is that the operation is strong, especially in the first gear operation is most obvious. In the engine matching, well-known foreign companies pay more attention to the engine power reserve
