Description
Technical field
The present invention relates to the auto body parts, be specifically related to a kind of automobile rear floor strength beam reinforcement assembly.
Background technology
The suffered power of automobile rear floor strength beam is carried bigger, and in order to make automobile steady safety in the process of moving, general automobile all contains reinforcement at this position, to strengthen the ability of bearing load of back-floor reinforcement beam.
Existing automobile rear floor strength beam reinforcement assembly; As shown in Figure 7; On the high side and the complex structure of the architectural feature of its strength beam reinforcement 1 offers three negative and positive shape circular holes 14 on the strength beam reinforcement 1, and is provided with the welding heavy stand of some irregular alignments; Find that through punching press shop characteristic and mechanical property after 14 moulding of negative and positive shape circular hole are unsatisfactory; Influenced the locating effect of strength beam reinforcement 1, found through cae analysis (promptly finding the solution the structural mechanical property of Analysis of Complex engineering and product with area of computer aided), the irregular alignment structure of welding heavy stand makes the stressed of strength beam reinforcement 1 relatively poor with the ability of the power of transmission; Simultaneously; Existing strength beam reinforcement 1 is not considered the installation question with the back trailing arm; Trailing arm directly makes bolt together on the automobile rear floor strength beam behind the automobile, and the nut mounting hole that is provided with on the back-floor reinforcement beam makes back-floor reinforcement beam rigidity be affected, and layout structure is more crowded; The layout that is unfavorable for miscellaneous part has limited the raising of automobile total quality.
Summary of the invention
The purpose of this invention is to provide a kind of automobile rear floor strength beam reinforcement assembly, strengthening its rigidity and intensity, and the back trailing arm can be installed.
Automobile rear floor strength beam reinforcement assembly of the present invention, comprise the strength beam reinforcement, with the back trailing arm nut sleeve mounting bracket and the back trailing arm nut sleeve mounting bracket reinforcement of strength beam reinforcement welding.
One side of said strength beam reinforcement is provided with upwards first flange of bending; Opposite side is provided with upwards second flange of bending; One end of strength beam reinforcement offers key shaped location via hole; The other end is provided with U-shaped welding heavy stand; Strength beam reinforcement near U-shaped welding heavy stand is provided with the circular weld boss, and offers negative and positive shape circular hole, and first flange place side of the strength beam reinforcement between key shaped location via hole and circular weld boss has the circular arc depression to second flange place side direction; Key shaped location via hole not only can be used for the welding location; Location when also can be used for general assembly simultaneously; Belong to the high-mobility, multipurpose, wheeled vehicle hole; Location when negative and positive shape circular hole is used to weld, U-shaped welding heavy stand and circular weld boss are used for and the back-floor reinforcement beam welding, and the circular arc depression is used for cooperating with back trailing arm nut sleeve mounting bracket and back trailing arm nut sleeve mounting bracket reinforcement.
Trailing arm nut sleeve mounting bracket middle part, said back offers and the cooresponding internal thread hole of nut sleeve; The one of which side is provided with upwards the 3rd flange of bending; The 4th flange that is complementary with said circular arc depression that opposite side middle part is provided with downward bending, the lower surface at the circular arc depression position of the upper surface of the 4th flange and said first flange welds; Nut sleeve is welded on the internal thread hole place; The axle center of nut sleeve is identical with the axle center of internal thread hole; Back trailing arm is installed on the trailing arm nut sleeve mounting bracket of back through nut sleeve; Back trailing arm nut sleeve mounting bracket is welded on the strength beam reinforcement, strength beam reinforcement and back-floor reinforcement beam welding, thus the back trailing arm is installed on the back-floor reinforcement beam.
One side of said back trailing arm nut sleeve mounting bracket reinforcement is provided with upwards the 5th flange of bending; Opposite side is the circular arc that is complementary with said circular arc depression; The two ends of back trailing arm nut sleeve mounting bracket reinforcement are respectively arranged with " mouth " font welding heavy stand; It is positioned at the strength beam reinforcement, through said the 5th flange and the welding of said second flange, through the opposite side and the welding of said circular arc depression of back trailing arm nut sleeve mounting bracket reinforcement; Through " mouth " font welding heavy stand and the welding of strength beam reinforcement, strengthened Joint strenght with the strength beam reinforcement.
The present invention adopts strength beam reinforcement, back trailing arm nut sleeve mounting bracket and back trailing arm nut sleeve mounting bracket reinforcement to form reinforcement assembly jointly; The strength beam reinforcement is accomplished with the welding of other parts through key shaped location via hole harmonizing yinyang shape circular hole and is located; Reduced because the rigidity of structure and the loss of strength that opening too much causes; U-shaped welding heavy stand has improved the rigidity of strength beam reinforcement; The circular arc of one of which side is recessed under the prerequisite of the rigidity that do not reduce the strength beam reinforcement and intensity, has saved installing space greatly; Back trailing arm nut sleeve mounting bracket adopts flange and the welding of strength beam reinforcement that is complementary with the circular arc depression, and adopts bolt connecting mode to be connected with the back trailing arm, and it is flexible to have increased car body, the stability when having improved running car; Back trailing arm nut sleeve mounting bracket reinforcement and strength beam reinforcement weld, and have improved the rigidity and the intensity of strength beam reinforcement; Though the shared space of space that this strength beam reinforcement assembly is shared and existing strength beam reinforcement assembly is basic identical, its rigidity and intensity are able to strengthen, and have also increased the function that the back trailing arm is installed simultaneously.
