Described left longitudinal tubule (L tubule) assembly is identical with right longitudinal tubule (L tubule) assembly structure, left longitudinal tubule (L tubule) assembly by front lining sleeve pipe, longitudinal tubule (L tubule) beam, after Bushing sleeves constitute, longitudinal tubule (L tubule) beam one end connection front lining sleeve pipe, the other end connection back bush sleeve pipe, toe-in control arm support, on Control arm support, stabilizer bar arm, trapezoidal arm support are arranged on the tube wall of longitudinal tubule (L tubule) beam.
Described rear cross beam assembly is made up of rear cross beam back plate and rear cross beam foreboard, and rear cross beam back plate and rear cross beam foreboard are solid Fixed connection, two ends form " Y " character form structure, and master subtracts after the middle part that bushing sleeves are arranged on rear cross beam assembly, rear cross beam assembly Left and right convex shape hole is provided with the middle part of crossbeam foreboard.
Good effect of the present utility model be its by entirety and partial structurtes optimization design, both met intensity, NVH It can require, be easy to suspension packing, bushing dismounting again;The application of common material and good process, makes design have low cost again Advantage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is bottom view of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings:As Figure 1-3, secondary car after a kind of new automobile Frame, it is characterised in that:Front beam assembly 2, the two ends of rear cross beam assembly 6 are fixedly connected with right longitudinal tubule (L tubule) assembly 1 and left longitudinal tubule (L tubule) assembly 3 Into a tower structure;The position that right longitudinal tubule (L tubule) assembly 1 and left longitudinal tubule (L tubule) assembly 3 overlap angle with front beam assembly 2 is fixedly connected with Front beam reinforcing plate 4 with groove, the rear cross beam reinforcing plate 5 with drop repeated hole is fixedly connected with the side of rear cross beam assembly 6, Subframe reinforcing plate 7 is fixedly connected between the bottom surface of front beam assembly 2 and rear cross beam assembly 6.
Described front beam assembly 2 is formed by fixedly connecting by front beam upper plate 2-1 and front beam lower plate 2-2, in front beam Portion reinforcing plate 2-3 is fixedly connected on front beam lower plate 2-2 and reinforced, and nut box 2-4 is fixedly connected on front beam internal reinforcing plates On 2-3.The square nut of activity is placed with nut box 2-4, movable nut compensate for the manufacturing tolerance of main reducing gear, make suspension Packing is more convenient and flexible.
Described left longitudinal tubule (L tubule) assembly 3 is identical with the right structure of longitudinal tubule (L tubule) assembly 1, and left longitudinal tubule (L tubule) assembly 3 is by front lining sleeve pipe 3-1, vertical Pipe beam 3-4, back bush sleeve pipe 3-5 are constituted, longitudinal tubule (L tubule) beam 3-4 one end connection front lining sleeve pipe 3-1, other end connection back bush sleeve pipe 3-5, toe-in control arm support 3-2, upper suspension arm support 3-3, stabilizer bar arm 3-6, trapezoidal arm support 3-7 are arranged in longitudinal tubule (L tubule) On beam 3-4 tube wall.Left longitudinal tubule (L tubule) assembly 3 is integrated with 2 sleeve pipes, 4 supports totally six tie points, and integrated rate is high, follow-up flat Platform vehicle can directly borrow part assembly, reduce R&D costs, reduce the production cycle.
