For the multi link formula Rear secondary frame for vehicle of rear-guard or 4 wheel driven vehicle, it is connected with components such as vehicle body, suspension and connecting rods, In Under the premise of meeting rigidity, intensity and reliability, also need to meet light-weighted requirement.Traditional multi link Rear secondary frame for vehicle is mostly by metal plate Golden welding forming, structure is complicated, and weight is big, and welding, assembly technology require height, and dimensional accuracy and reliability are lower.Aluminium alloy material Although material is conducive to the lightweight of subframe, this can dramatically increase the cost of subframe.
Summary of the invention
The purpose of this utility model is to provide a kind of Rear secondary frame for vehicle, and the technical problem to be solved is that how to overcome tradition The defects of metal plate welding multi link formula back-auxiliary cycle frame structure is complicated, weight is heavy, welding deformation is big, poor reliability.
Rear secondary frame for vehicle described in the utility model includes front beam assembly and the rear cross beam assembly opposite with front beam assembly, The front beam assembly is welded to form by front beam upper tube beam and front beam down tube beam by two front beam connecting tubes, rear horizontal Beam assembly is welded by rear cross beam upper tube beam and rear cross beam down tube beam and motor power assembly rear suspension bracket;Front beam assembly Left and right stringer is fixedly connected with rear cross beam assembly two sides, the left and right both ends of front beam assembly upper pipes beam are respectively fixed with and vehicle The front beam assembly vehicle body connection sleeve of body installation connection being symmetrical set;Left and right the two of rear cross beam assembly upper pipes beam End, which is respectively fixed with, connects sleeve with the rear cross beam assembly vehicle body of vehicle body installation connection being symmetrical set.
The rear cross beam upper tube beam and rear cross beam down tube beam is bend pipe beam.
Be fixed on the left and right stringer symmetrical front lower oscillating arm bracket, intermediate upper suspension arm connecting rod rack, after Upper suspension arm connecting rod rack and rear middle control arm connecting rod rack, symmetrical back lower controlling arm connecting rod rack is fixed on left and right The lower beam lap-joint of stringer and rear cross beam assembly.
Symmetrical side suspension installation casing is installed in the front of left and right stringer.
Rear-suspending installation casing is installed at rear cross beam assembly rear suspension bracket.
The left and right stringer is respectively arranged with side rail and girder plate.
The technical solution of the utility model has the advantages that
Back-auxiliary cycle frame structure described in the utility model is simple, and left and right stringer assembly is welded by two pieces of punching press metal plates At, improve the performance and reliability of structure, convenient for the fixation of multi link bracket, at the same for prop shaft arrangement leave a blank in advance Between.Front beam assembly, rear cross beam assembly and left and right stringer assembly have collectively constituted the integral frame structure of subframe.Forward and backward cross The left and right both ends of beam assembly upper pipes beam are respectively fixed with the casing with vehicle body installation connection, are connected by bushing and vehicle body flexibility It connects, the vibration in incoming compartment can be reduced, improve vehicle driving comfort.
