Detailed description of the invention

A kind of low speed EMUs monoblock type run-through channel, as shown in Figure 1 and Figure 2, forms the 1, first pedal 2, cab apron 3 and the second pedal 4 including vestibule diaphragm, and described vestibule diaphragm composition is bolted and is fastened on end wall of car body 5,6. Described first pedal the 2, second pedal 4 is fastened on car body floor face by sunk screw. In cab apron 3 structure, there are two bearing pins bottom surface, relies on the circular hole that gravity is overlapped on the first pedal 2 to neutralize in the U-type groove of the second pedal 4 respectively.

This utility model considers the working line situation that low speed motor-car is good, vestibule diaphragm design is adopted to substitute side wall, crown wall structure, wherein vestibule diaphragm forms by interior, outer vestibule diaphragm is formed and is formed by connecting by connecting plate bolt, interior vestibule diaphragm is to contact with motor-car passenger, belong to car body interior structure, thus instead of the side wall of tradition run-through channel and crown wall effect, because vestibule diaphragm composition is to form by sewing between canopy cloth, every ring canopy cloth is connected by aluminum section bar frame clamping, its structure has good pliability, the operating condition condition of motor-car can be met, adopt the design of two-layer canopy cloth simultaneously, there is good sound insulation, heat insulation and sealing.
