Problem described in the utility model realizes with following technical proposals:
A kind of automobile spare tire lifting crossbeam, it is positioned at the rear portion of vehicle frame, be installed between the chassis side rail of both sides, its special feature is: described spare tyre lifting crossbeam mates with the spare tyre position-limited lever that is installed in the spare tyre limit base on the vehicle frame front cross rail and be installed on the Aft cross member, and described spare tyre lifting crossbeam is the single-piece integral structure.
Above-mentioned automobile spare tire lifting crossbeam, its cross-sectional plane is the flat trench structure of inversion that both sides have horizontal flange, also is provided with vertical flange upwards at the outer ledge of its horizontal flange.
Above-mentioned automobile spare tire lifting crossbeam is provided with spare tyre suspension bracket mount pad at its flat-bottom slot end face, and described spare tyre suspension bracket mount pad is provided with the hold-down bolt hole.
Above-mentioned automobile spare tire lifting crossbeam also is provided with one group of lightening hole on its flat-bottom slot end face, described lightening hole is symmetrically arranged.
Above-mentioned automobile spare tire lifting crossbeam, the spare tyre that is welded at its two ends lifting beam brace panel, described spare tyre lifting beam brace panel is the left-right symmetric structure, they also assemble with the welding of both sides chassis side rail respectively.
The utility model has improved counter-bending rigidity and the torsional rigidity of spare tyre lifting crossbeam with its distinctive cross-sectional structure; The utility model arranges spare tyre lifting crossbeam brace panel at spare tyre lifting crossbeam and chassis side rail lap position place, has improved the Joint strenght of spare tyre lifting crossbeam and chassis side rail; The related spare tyre lifting crossbeam of the utility model is the single-piece integrated formed structure, and is provided with lightening hole at its inverted flat-bottom slot end face, has satisfied the requirement of car load weight-saving; The utility model be installed in the vehicle frame front cross rail on the spare tyre limit base and the spare tyre position-limited lever that is installed on the Aft cross member cooperate, not only guaranteed the stationarity of spare tyre lifting, and by vehicle frame front cross rail and Aft cross member, share the different directions force of inertia that in the vehicle driving process, is produced by spare tyre, alleviated the impact load that spare tyre lifting crossbeam bears.In a word, the utlity model has characteristics simple in structure, cheap, as to be easy to the through engineering approaches batch manufacturing, both guaranteed spare tyre lifting stability, meet the requirement of car load weight-saving again, promoted tractive performance and the economic performance of vehicle.
