前、后横梁在振动压路机中主要起到两个作用:一是连接压路机前、后机身;二是合理分配前、后机身重量。介绍一种填充式横梁结构及其制造工艺。该横梁可以替代传统的厚板结构和实体铸造横梁,从而达到有效减少材料费用,降低制造成本,提高产品市场竞争力的目的。 Before and after the beam in the vibration roller mainly plays two roles: First, connect the roller front and rear fuselage; the second is the rational distribution of body weight before and after. A kind of filled beam structure and its manufacturing process are introduced. The beam can replace the traditional thick plate structure and physical casting beams, so as to effectively reduce the cost of materials, reduce manufacturing costs, improve product market competitiveness purposes.
