Retarder cross beam for auxiliary support of lightweight integrated power assembly

The utility model relates to a retarder cross beam of a light-weight integrated power assembly auxiliary support, which solves the problems that the existing auxiliary supports are respectively arranged on the inner sides of a left longitudinal beam and a right longitudinal beam, the weight is larger and the cost is higher. Comprising angle bearing pieces, transition base plates and cross beams, the angle bearing pieces are angle iron, the transition base plates and the cross beams are rectangular pipes with different section sizes, the angle bearing pieces are fixedly connected with the transition base plates in a bolt connection mode, and the cross beams are fixedly connected with the transition base plates in a bolt connection mode. Each end face of each part of the whole structure is connected through four sets of bolts, the middle of the lower surface of the cross beam is hollowed out, and a kidney-shaped hole is formed in the middle of the upper surface of the cross beam and used for connecting a lower
