Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
The lateral rigidity that Fig. 1 and Fig. 5 shows a kind of trailing arm attachment point strengthens structure, comprise rear trailing arm support 1, rear trailing arm bracket reinforcing plate 2, solid round rod 3 and front floor body 4, rear trailing arm support 1 and rear trailing arm bracket reinforcing plate 2, by solder joint weld together, form rear trailing arm bracket assembly.Rear trailing arm bracket assembly has two, is symmetrical arranged about car load longitudinal plane, and is welded on respectively on the longeron at two ends, vehicle body left and right.Solid round rod 3 has two, is also symmetrical arranged about car load longitudinal plane, and one end of solid round rod 3 is fixedly connected with the rear trailing arm bracket assembly of corresponding side, and the other end of solid round rod 3 is fixedly connected with near the position of middle passage with front floor body 4.
As depicted in figs. 1 and 2, solid round rod 3 is long pole spars of round section, each one and longitudinally (vehicle body fore-and-aft direction) symmetrical plane is symmetrical along car load of vehicle body left and right sides, this oval bar suggestion diameter 14mm, to guarantee that it has enough rigidity and can keep the continuity of rigidity, by extrusion process, port is flattened at solid round rod two ends, open bolt hole 31, to be connected with rear trailing arm bracket assembly and front floor body 4 by bolt at the port flattened.This structure design is the reason of round bar is that circle has good bending resistance torsional property, can effectively resistance to deformation the load transmitted between vehicle body and towing arm.For avoiding load excessive and the equal strength problem that occurs ftractureing, this round bar adopts the steel that intensity is higher.
As shown in Figure 3, rear trailing arm support 1 comprises riser 11, and riser 11 periphery has many flange can be welded to connect with chassis runner and all edge pieces, comparatively large owing to bearing load herein, so require more welding edge number, so that the transmission of load.Riser 11 center is provided with the first mounting hole 111.Rear trailing arm bracket reinforcing plate 2 and riser 11 are welded to connect.As shown in Figure 4, rear trailing arm bracket reinforcing plate 2 is also provided with the second mounting hole 21, first mounting hole 111 and the second mounting hole 21 coaxial line with the first mounting hole 111 corresponding position to be bolted with the bolt hole 31 of solid round rod 3 one end.Rear trailing arm bracket reinforcing plate 2 periphery also has multiple flange to be welded to connect with chassis runner and all edge pieces.Comparatively large owing to bearing load herein, so require more welding edge number, so that the transmission of load.
As shown in Figure 5, front floor body 4 is massive plate part, is designed with feature muscle to increase its rigidity, and in its plane, leave the 3rd mounting hole 41 installing solid round rod 3 other end near middle channel position.3rd mounting hole 41 has two, is symmetricly set on the both sides of middle passage and the position of close middle passage along longitudinal (vehicle body fore-and-aft direction) symmetrical plane of car load.Two the 3rd mounting holes 41 are bolted with the bolt hole 31 of solid round rod 3 other end of respective side respectively.
On rear trailing arm support 1, rear trailing arm bracket reinforcing plate 2 and front floor body 4, the determination of each solid round rod 3 position of mounting hole considers based on following aspect, first guarantee that solid round rod 3 can Assembly &Disassembly easily, then solid round rod 3 should be noted the angle between itself and towing arm left and right attachment point line when arranging, also the angle namely between solid round rod 3 and the line of symmetrically arranged two rear trailing arm bracket assemblys controls as far as possible little, load can be ensured so as far as possible along the transfers of Circular Pipe, make it play maximum effect.
Towing arm attachment point lateral rigidity provided by the utility model strengthens structure and adopts filled circles steel pole to make, and takes up room little, is convenient to the layout of car load, and adopt bolt to install, for convenience detach.
After this utility model is implemented, CAE calculates new construction comparatively original design lateral rigidity lifting 17%, and concrete outcome sees the following form 1.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; obvious realization of the present utility model is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all in protection domain of the present utility model without to improve.
