Embodiment 1
[0030] Example 1, such as Figure 1 to Figure 3 As shown, the load-bearing air duct of the present invention is formed on the underframe of the rail vehicle, which is clamped by the left load beam 2 and the right load beam 1 on both sides of the vehicle body to form a hollow cavity.
[0031] An upper cover plate 3 and a lower cover plate 4 are closed and connected to the upper and lower end surfaces of the hollow cavity.
[0032] The front and rear end faces of the hollow cavity are closed and connected with a front beam 5 and a rear beam 6 .
[0033] One air inlet 9 is arranged on the upper cover 3 , and three air outlets 10 are arranged on the lower cover 4 to form a passage for air circulation.
[0034] A middle beam 7 is arranged inside the hollow cavity to divide the hollow cavity into three compartments, and an air outlet 10 is left on the lower cover plate 4 of each compartment 11 .
[0035] On the middle beam 7 between the air inlets 9 and the air outlets 10 belongin...

The invention relates to an under frame bearing duct of a railway vehicle and an installation method thereof, which cancels the prior duct device with an independent cavity and adopts a duct spliced by a closed connected cover plate and an end beam on the basis of a bearing duct owned by a bodywork under frame. On the basis of the bearing device originally owned by bodywork under frame to splice a duct, the existing under frame bearing structure is not destroyed, the prior bearing capacity is not reduced and the complete mechanical strength of the locomotive or a motor car is guaranteed. The under frame bearing duct of the railway vehicle is a hollow cavity formed and held by a left and a right carrier bars of the bodywork. An upper edge and a lower edge of the hollow cavity are sealed and closely connected with the cover plate. The front and back edges of the hollow cavity are connected with an end beam. The cover plate is provided with an air inlet and an air outlet used for ventilation.
Description
technical field [0001] The invention relates to a load-bearing air duct for a car body underframe of a rail vehicle locomotive or a motor car and an installation method thereof, belonging to the field of mechanical manufacturing. Background technique [0002] At present, the traction motors of locomotives or bullet trains of rail vehicles are generally arranged on the wheelsets of the bogies, while the fans are installed on the car bodies. Since the convection of the cooling air generated by the fan is used to perform air-cooling and cooling treatment on the traction motor, it is necessary to set a special air duct between the bogie wheel set and the vehicle body. [0003] The existing structure and cooling method is to set an air duct with an independent ventilation cavity between the fan and the traction motor, and the air duct is installed inside the chassis. This will destroy the structure of the original underframe load-bearing beam, and the manufacturing process is di...
