Abstract
The utility model provides a back auxiliary frame installation structure so as to improve stiffness and strength of an installation point of a back auxiliary frame and a car body, relieve the problem that lining is weak in the lengthways direction when a car brakes, share stress on a lining installation point when the car vertically bumps, prolong service life of the lining and the installation point and reduce damage risks caused by concentrated stress. The back auxiliary frame installation structure comprises a back auxiliary frame, a longitudinal beam and a cross beam, and the longitudinal beam and the cross beam are fixed in a welding mode. The back auxiliary frame installation structure is characterized in that the end portion lining of the back auxiliary frame is fixedly connected with a reinforced support, and two ends of the reinforced support are respectively and fixedly connected with the longitudinal beam and the cross beam through bolts. The back auxiliary frame installation structure is simple in structure, capable of improving stress on the installation point obviously, low in cost, easy to realize in production and convenient to assemble and disassemble, and has good practicability.
Description
Technical field
The utility model belongs to field of automobile, specially refers to a kind of Rear secondary frame for vehicle mounting structure that improves Rear secondary frame for vehicle and vehicle body attachment point rigidity and intensity.
Background technology
The skeleton of vehicle bridge before and after subframe can be regarded as, its effect are vehicle bridge and suspension holdfasts before and after supporting, intercept vibration and noise, play certain buffer action, and have strengthened the chassis rigidity, reduce it and directly enter the compartment.Subframe generally takes lining to be connected with the vehicle body point of connection, lining connects the vibrations that produce in the time of can completely cutting off running car well, but, thing followed problem is: unreasonable if 1 lining rigidity is selected, can produce larger longitudinal force during car brakeing, the softer lining of longitudinal rigidity can make the lining fracture lose efficacy or endurance failure in the used time of doing that is subject to longitudinal shear power; 2, under the jumping operating mode is hung down in single-wheel, the main Bending torque load of subframe, under larger moment of flexure or torsional interaction, make subframe and the one-sided tension of vehicle body point of connection, easily cause the lining junction destroyed, under the jumping operating mode of hanging down simultaneously, the subframe insufficient rigidity also can cause the structure partial failure, and the less subframe of rigidity can reduce the ride comfort of automobile in the process of moving.
Summary of the invention
The purpose of this utility model is to propose a kind of Rear secondary frame for vehicle mounting structure, to improve Rear secondary frame for vehicle and vehicle body attachment point rigidity and intensity, the vertical weak problem of lining when alleviating car brakeing, and lining attachment point place stressed when sharing vehicle and hang down jumping, improve the life-span of lining and attachment point, reduce the stressed destruction risk of bringing of concentrating.
Rear secondary frame for vehicle mounting structure of the present utility model comprises Rear secondary frame for vehicle, longeron, crossbeam, described crossbeam and longitudinal beam welding are fixed, key is that the end lining of described Rear secondary frame for vehicle captives joint with reinforced support, and the two ends of described reinforced support are bolted to connection with longeron, crossbeam respectively.
Be subject to longitudinal force or vertical force is done the used time at vehicle, Rear secondary frame for vehicle and vehicle body attachment point can be subject to car load vertically or vertical load.In the original structure design, the longitudinal force that Rear secondary frame for vehicle bears and vertical force are all by bearing with the direct coupled subframe lining of vehicle body, in structure of the present utility model, reinforced support can be shared vertical force and the longitudinal force of most Rear secondary frame for vehicle, thus the life-span of having improved lining and attachment point.
Further, described reinforced support comprises that two are the branch that acute angle distributes, and free end and the convergence of described two branches are provided with mounting hole; The lining both sides, end of described Rear secondary frame for vehicle respectively are equipped with a reinforced support, and two reinforced supports are symmetrical arranged.Two branches that are the acute angle distribution can make the integral structure of reinforced support tend towards stability, and two reinforced supports are symmetrical arranged, and are complementary to the longitudinal force of Rear secondary frame for vehicle, further guarantee the firm of Rear secondary frame for vehicle.
Further, the edge of described reinforced support has flange, and perhaps the branch of reinforced support is provided with convex tendon, with the integral rigidity of reinforced support, effectively prevents support generation buckling failure.
Further, the convergence of two branches of described reinforced support is provided with concave surface, so that the edge of liner sleeve is encased the location.
Rear secondary frame for vehicle mounting structure of the present utility model is simple in structure, and to improving the stressed comparatively obvious of attachment point place, cost is lower, is easy in production realize, and is convenient to Assembly ﹠Disassembly, has good practicality.

The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the Rear secondary frame for vehicle mounting structure of the present embodiment comprises Rear secondary frame for vehicle 1, longeron 2, crossbeam 3 and reinforced support 4, and crossbeam 2 is welded and fixed with longeron 3; Reinforced support 4 adopts sheet metal component to be stamped to form, and thickness 2mm comprises that two free end and convergences that are 41, two branches 41 of branch of acute angle distribution are provided with mounting hole 42; The lining both sides, end of Rear secondary frame for vehicle 1 respectively are equipped with a reinforced support 4, and two reinforced supports 4 are symmetrical arranged, and two branches 41 of reinforced support 4 are bolted to connection with longeron 2, crossbeam 3 respectively.
As shown in Figure 2, the edge of reinforced support 4 has flange 5, and the branch 41 of reinforced support is provided with convex tendon 6, with the integral rigidity of reinforced support, effectively prevents support generation buckling failure.In the time of Rear secondary frame for vehicle 1 bearing load, can be delivered on longeron 2 and crossbeam 3 by reinforced support 4.
As shown in Figure 3, the convergence of two branches 41 of reinforced support 4 is provided with concave surface 7, so that the edge of liner sleeve is encased the location.
Be subject to longitudinal force or vertical force is done the used time at vehicle, Rear secondary frame for vehicle 1 can be subject to car load vertically or vertical load with the vehicle body attachment point.In the original structure design, the longitudinal force that Rear secondary frame for vehicle bears and vertical force are all by bearing with the direct coupled subframe lining of vehicle body, in structure of the present utility model, reinforced support 4 can be shared vertical force and the longitudinal force of most Rear secondary frame for vehicle 1, thus the life-span of having improved lining and attachment point.
