The technical scheme of the utility model is that a structure of back air suspension undersetting based on 6 meters pure electric city passenger train, including U type seat bottom and a side fixed connection of the type of falling L undersetting, the type of falling L undersetting another side respectively fixed connection reinforcing plate and distance rod fixing base bottom plate be formed with one side open-ended cavity structures, distance rod fixing base bottom plate lateral surface fixed connection distance rod fixing base, bumper shock absorber mount pad and stabilizer bar installing support fixed connection in U type seat and the type of falling L undersetting connect the lateral surface that forms.
Preferably, the joint of the thrust rod fixing seat and the thrust rod fixing seat bottom plate is fixedly connected with the thrust rod fixing seat reinforcing rib.
Preferably, the U-shaped seat is fixedly connected with the upper reinforcing plate on one side surface adjacent to the reinforcing plate.
Preferably, the bottom of the U-shaped seat and the connecting surface of the inverted L-shaped lower support are provided with mounting holes communicated with each other.
Preferably, a 2# reinforcing rib is arranged at the joint of the shock absorber mounting seat and the U-shaped seat.
Preferably, a 1# reinforcing rib is arranged at the connection position of the stabilizer bar mounting bracket and the U-shaped seat.
Preferably, the stabilizer bar mounting bracket is of an inverted L type, and the other side surface of the stabilizer bar mounting bracket is fixedly connected with the outer side surface of the shock absorber mounting seat.
Preferably, the stabilizer bar mounting bracket and the vertical surface of the U-shaped seat are provided with mounting holes.
The utility model has the advantages that:
(1) the optimal design arrangement of the whole vehicle is fully ensured;
(2) the integration level of the whole structure is higher;
(3) the convenience of the whole vehicle in installation and maintenance is ensured;
(4) the manufacturing cost is low; on the basis of the structure of the lower support of the rear air suspension commonly used at present, the overall design thought and the overall structural design are optimized and adjusted, so that the overall design structure is more compact, simpler, more convenient and more practical, and the manufacturing cost is lower.
