FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the assembly structure of the present invention.
Description of reference numerals: 1. a rear cross member front plate; 2. a rear cross member rear panel; 3. the lapping is quick; 4. a closed cavity; 5. reinforcing ribs; 6. mounting a boss; 7. lightening holes; 8. a weight-reducing cavity; 9. a rear suspension mounting hole; 10. a trailing arm; 11. a rear cross beam body.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the figure, the auxiliary frame rear cross beam comprises a rear cross beam body 11, wherein the rear cross beam body 11 is composed of a rear cross beam front plate 1 and a rear cross beam rear plate 2, the rear cross beam front plate 1 and the rear cross beam rear plate 2 form a horizontal splayed structure, the left end and the right end are outwards stretched to be connected with a longitudinal arm 10 of an automobile auxiliary frame, and the horizontal splayed rear cross beam enables the rear cross beam to outwards expand from the middle to the two sides until the rear cross beam is connected with the longitudinal arm, so that the connection area of the two sides of the rear cross beam and the longitudinal arm is increased by more than one time, the torsional rigidity of the whole auxiliary frame is greatly improved, the stress borne by the longitudinal arm or the rear cross beam can be uniformly dispersed, the local stress borne by the rear cross beam and the longitudinal arm is greatly reduced, meanwhile, the reinforcement of the rear cross beam also provides a more stable mounting platform for a rear control arm mounting bracket mounted on a rear balance, Strength and fatigue properties.
The rear cross beam front plate 1 and the rear cross beam rear plate 2 are connected through a lapping block 3. The lapping blocks 3 inwards form a plurality of closed cavities 4, and the outer ends of the lapping blocks 3 and the longitudinal arms 10 form weight reducing cavities 8. The frame type auxiliary frame needs to be made larger by the rear cross beam in order to ensure better mode, so that the weight of the auxiliary frame can be greatly increased, a closed cavity formed by the lap joint blocks can transmit the force between the front plate and the rear plate of the cross beam and can play a good weight reducing role, when the front plate and the rear plate of the rear cross beam extend outwards, a weight reducing cavity is formed, the rear cross beam is fully connected with the longitudinal arm, a good weight reducing effect can be formed, in addition, in a connecting area with the longitudinal arm, the upper plate of the cross beam is recycled towards the middle, in the process of reducing weight, the contact area between the rear cross beam and the longitudinal arm is increased, and the effect of reducing local stress and improving the connecting rigidity is achieved.
Rear control arm mounting bosses 6 which are bilaterally symmetrical are arranged on the front plate 1 and the rear plate 2 of the rear cross beam, rear suspension mounting holes 9 are formed in the mounting bosses 6, and reinforcing ribs 5 which protrude in the opposite direction of the mounting bosses 6 are arranged at two ends of each rear suspension mounting hole 9. The rear suspension mounting hole 9 is arranged to provide positioning and mounting effects for the rear control arm, and the mounting boss 6 can be used as a positioning surface for mounting a control arm bushing through a convex surface on one hand, so that mounting and positioning are facilitated; on the other hand, the convex structure can improve the rigidity and the strength of the mounting bracket, and the reinforcing ribs 5 protruding in the opposite direction of the mounting boss 6 can further improve the rigidity and the strength of the mounting surface and reduce the deformation and the stress concentration of the mounting bracket.
The two sides of the front plate 1 and the rear plate 2 of the rear cross beam are provided with a plurality of lightening holes 7, the lightening holes 7 are arranged in bilateral symmetry, and each lightening hole 7 is provided with a flanging structure. The large lightening holes 7 arranged in the regions where stress and rigidity are insensitive have a very remarkable effect on lightening the auxiliary frame, and meanwhile, the flanging arranged at the lightening holes 7 can greatly weaken the effect of rigidity reduction caused by hole excavation.
The utility model discloses the problem that sub vehicle frame structure is complicated among the prior art, the mode is low, the rigidity is not enough has been solved to the structure.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
