Cab

Abstract

The invention relates to a cab. The cab comprises two door upright columns, two longitudinal beams, a main cross beam, two main upright columns and an upper cross beam, wherein the two door upright columns are arranged on the side walls on the two sides of the cab respectively; one end of each longitudinal beam is arranged on a top cover of the cab, while the other end is arranged on the main cross beam; the main cross beam is positioned below a front wind of the cab; the two ends of the main cross beam are connected with the two door upright columns respectively; the main upright columns are arranged between the main cross beam and the floor of the cab; the upper cross beam is positioned between the two longitudinal beams; the two ends of the upper cross beam are connected with the two longitudinal beams; and the door upright columns, the longitudinal beams, the main cross beam, the main upright columns and the upper cross beam are formed by performing cold bending on hollow aluminum profiles. When 300 KN of longitudinal pressure is applied to the main cross beam under the front window of the cab, the force is delivered to the vehicle body through the longitudinal beams, the door upright columns and the main upright columns, so that the cab has no obvious deformation and the safety of a driver is ensured to a great extent.

Description

Technical field: [0001] The invention relates to a driver's cab of an urban rail vehicle body, in particular to a driver's cab made of cold-bent hollow aluminum profiles, and the front window can withstand a longitudinal pressure of 300KN. Background technique: [0002] At present, the streamlined driver's cab structure of domestic subway vehicles mainly includes door columns 10 and longitudinal beams 20, such as figure 1 As shown, most of the socket-type plate beam structures are used. Except for the door column 10, other structures are all made of 8-10mm aluminum plates, and the skeleton is distributed into a network structure according to the shape of the hood. This type of plate beam structure has serious deformation after welding. , Subsequent installation of the fiberglass hood is difficult, heavy, and difficult to bear 300KN longitudinal pressure under the front window of the driver's cab, so the purpose of protecting the driver to the maximum cannot be achieved.
