大中型客车外蒙皮覆盖技术分析

Analysis on the Covering Technique of Medium and Large Coach Outer Skin

国内大客车的外蒙皮一般采用玻璃钢或冲压件,蒙皮之间的接缝都是采用填充玻璃钢树脂或刮腻子来解决。这种填缝结构容易开裂、漏水,而且在生产过程中粉尘污染比较大。国外的客车普遍都采用冲压件蒙皮,接缝处采用填缝胶来处理,能很好地避免这些问题。

The outer skin of large coaches is domestically made of fiberglass or stamping parts, the seam between outer skins is filled with fiberglass or putty powder. This structure is easy to crack and leaking,and the dust pollution in the production process is relatively remarkable. The coach outer skin abroad is widely made of stamping parts and the seam is filled with caulking glue, this structure can be very helpful to avoid above problems.
