The bridge type cross beam assembly comprises a bridge type cross beam which is formed by fixing an upper bridge type cross beam, a lower bridge type cross beam and a rubber layer between the upper and lower bridge type cross beams, wherein an elastic pad is arranged on the top surface of the upper bridge type cross beam; supporting columns are also fixed on the top surface of the upper bridge type cross beam; a mounting seat is fixed on the top surfaces of the supporting columns; compression springs are arranged on the outer walls of the supporting columns in a sleeving manner; a heat dissipation cavity is formed in a cavity between the mounting seat and the elastic pad; through holes communicated with the heat dissipation cavity are formed in the mounting seat; mounting slots for mounting heat dissipation fans are formed in the bottom surface of the lower bridge type cross beam; air ducts are formed in the bottom surfaces of the mounting slots; the air ducts are communicated with the heat dissipation cavity; a temperature sensor is mounted on the mounting seat; a signal of the temperature sensor is connected into a sensor so as to be connected with the heat dissipation fans in a control manner. By the arrangement of various shock absorption structures, the bridge type cross beam assembly is good in shock absorption effect; furthermore, by the arrangement of multiple through holes and the air ducts which are communicated with the heat dissipation cavity, the heat dissipation effect is enhanced; meanwhile, the temperature sensor controls the heat dissipation fans in a sensing manner, so that the service life of an automobile can be prolonged.
