Description

technical field [0001] The present invention relates to a carriage, in particular to a freight car carriage. Background technique [0002] A van is a compartment with an independent, closed structure or an integral closed structure compartment together with the cab, equipped with special facilities for carrying passengers or goods or undertaking special operations. At present, most of the vans are based on the chassis of the second-class trucks and install an independent closed compartment. The box body is composed of six pieces of top cover, bottom frame (including subframe longitudinal beams and beams), front wall, rear wall (rear door frame), and left and right side walls. Therefore, for the freight car body, the carriage frame is particularly important. The main features of the existing wooden carriage are that it is easy to manufacture and repair, but it has a short service life, poor moisture-proof and anti-corrosion performance, is not environmentally friendly, and ...
