Described beam comprises fixed base plate and pressure-bearing top board, tool rubber blanket between fixed base plate and pressure-bearing top board.

The two ends of described fixed base plate are provided with upwardly extending spacing preiection, and pressure-bearing top board two ends are provided with the spacing preiection to downward-extension, have gap and position is corresponding one by one between the spacing preiection on fixed base plate and limit convex on pressure-bearing top board.

Be in the inner side of bearing plate of the beam of crossbeam and longeron middle part along turning edge of turning under having.

On the termination of described crossbeam, be welded with end plate, described tie rod seat revolves and is located in the screwed hole of offering on end plate.

On longeron of the present utility model, be provided with five beams, wherein another one is in middle part, in other four two are in one end of longeron, another two other ends that are in longeron, the middle part of two crossbeams is respectively arranged with a beam, like this, the weight of car can be shared the four corners position of bracket, and the tie rod seat of crossbeam end is used for arranging tie rod screw rod, tie rod screw rod can be assigned to the part in the weight of car in vertical beam, beam is effectively acted on the following stress point using, play optimum damping and support effect.
