The invention provides a carriage, a roof of the carriage and a passenger car with the roof, and belongs to the technical field of rail transit equipment manufacturing. The roof comprises a high-roofcamber beam, a high-roof skin and an equipment mounting beam group, the high-roof skin covers the plurality of high-roof camber beams which are distributed at intervals along the length direction of the roof; the equipment mounting beam group extends along the length direction of the roof and is fixed on the high roof skin; the high-top camber beam is of an integrated structure manufactured through a stretch bending process. And the equipment mounting beam group is used for mounting equipment. The full-length car roof made of the stretch-bending integrated high-top camber beam has no difference between a high top and a flat top in the car roof production process, the total number of parts and the welding amount required by car roof forming are reduced, the production period of the whole product is shortened, and the production cost of the whole product is reduced.
本发明提供一种车厢及其车顶,以及具有该车顶的客车,属于轨道交通装备制造技术领域。其中,车顶包括:包括:高顶弯梁、高顶蒙皮以及设备安装梁组;所述高顶蒙皮包覆沿着所述车顶的长度方向间隔分布的多根所述高顶弯梁上;所述设备安装梁组沿着所述车顶的长度方向延伸并固定在所述高顶蒙皮上;所述高顶弯梁为通过拉弯工艺制成的一体式结构;所述设备安装梁组用于安装设备。通过采用拉弯一体式的高顶弯梁制成的通长车顶,在车顶生产时无高顶、平顶之分,减少了车顶成型所需的零件总数和焊接量,缩减了整个产品的生产周期和生产成本。
