The purpose of this utility model is mainly achieved by following proposal: a kind of electronlmobil subframe, comprise subframe body, described subframe body comprises two longerons and the front cross rail between longeron and after cross member, front cross rail, after cross member and longeron are tubular structure, the two ends of front cross rail are provided with the riveting-rack for being connected with vehicle body, longeron is provided with oscillating arm bracket, front cross rail and after cross member are provided with dynamic assembly mounting bracket, between front cross rail and after cross member, are provided with at least one deep beam.Subframe body comprises two parallel longerons and the front cross rail between two longerons and after cross member, and front cross rail, after cross member and longeron are tubular structure, namely subframe body is spliced by the crossbeam of tubular structure and longeron, reduces the own wt of subframe body.Front cross rail, after cross member are fixedly connected with longeron junction, and because front cross rail, after cross member and longeron are tubular structure, contact point is few, area of contact is little, are convenient to welding, are convenient to produce, save production time.The front cross rail of tubular structure, after cross member and longeron are not flexible, can strengthen self structure intensity, prevent subframe body distortion.The two ends of front cross rail are provided with the riveting-rack for being connected with vehicle body, longeron is provided with oscillating arm bracket, front cross rail and after cross member are provided with dynamic assembly mounting bracket, under enabling subframe body ensure the prerequisite of structural strength, are enough to the important feature of carrying motor and retarder.Be provided with at least one deep beam between front cross rail and after cross member, utilize deep beam to support two longerons, ensure that two longerons remain parallel, strengthen the structural strength of subframe body, avoid two longeron distortion.
As preferably, described front cross rail, the after cross member part between two longerons is linear structure.When two longerons are under pressure, when pressure is delivered on front cross rail and after cross member, pressure is along the axis direction of front cross rail and after cross member, front cross rail, the after cross member part between two longerons is made to be linear structure, ensure pressure all the time along the axis direction of front cross rail and after cross member, avoid front cross rail and after cross member to be subject to torsion, avoid front cross rail and after cross member distortion.
As preferably, the two ends grafting vertical with longeron of described deep beam is also welded and fixed at splicing position.The two ends grafting vertical with longeron of deep beam, namely the end vertical longeron of deep beam extends through in longeron, and longeron can support deep beam, strengthens the Joint strenght of deep beam and longeron, and be welded and fixed at splicing position, strengthen the Joint strenght of deep beam and longeron further.
As preferably, described front cross rail is vertical grafting with after cross member and longeron and is welded and fixed at splicing position.Front cross rail grafting vertical with longeron with the two ends of after cross member, namely the end vertical longeron of front cross rail and after cross member extends through in longeron, longeron can support front cross rail and after cross member, strengthen the Joint strenght of front cross rail and after cross member and longeron, and be welded and fixed at splicing position, strengthen the Joint strenght of front cross rail and after cross member and longeron further.
As preferably, the section of described front cross rail, after cross member, deep beam and longeron is circle.
Therefore, electronlmobil subframe of the present utility model possesses following advantage: subframe body comprises two parallel longerons and the front cross rail between two longerons and after cross member, and front cross rail, after cross member and longeron are tubular structure, namely subframe body is spliced by the crossbeam of tubular structure and longeron, reduces the own wt of subframe body.Front cross rail, after cross member are fixedly connected with longeron junction, and because front cross rail, after cross member and longeron are tubular structure, contact point is few, area of contact is little, are convenient to welding, are convenient to produce, save production time.The front cross rail of tubular structure, after cross member and longeron are not flexible, can strengthen self structure intensity, prevent subframe body distortion.
