Description
Technical field
The invention belongs to automobile technical field, specifically, particularly rear torsion beam assembly and the body component connection structure on automobile.
Background technology
Automobile rear torsion beam assembly is connected with body component bolt by rubber bush assembly.At present, the no guide fixed position of rear torsion beam assembly and body component connection structure mechanism, more difficult when torsion beam trailing arm after assembling, be difficult to carry out hole to locate with body bolt mounting hole rapidly and accurately, make its fitting process loaded down with trivial details, thereby affected the efficiency of assembling.In addition, after assembling completes bolted, easily cause rubber bush assembly to present undernatured state, the effect of preloading power, the service life of having reduced rubber bush assembly from assembly technology.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of automobile rear torsion beam assembly and body component connection structure that can contraposition convenient for assembly.
Technical scheme of the present invention is as follows: a kind of automobile rear torsion beam assembly and body component connection structure, comprise rear torsion beam assembly (1), rubber bush assembly (2) and body component (3), the two ends, left and right of described rear torsion beam assembly (1) are trailing arm (4), the front end of each trailing arm (4) is all fixed with rubber bush assembly (2), the position of the upper corresponding rubber bush assembly (2) of described body component (3) is provided with mounting groove (3a), in the left and right cell wall of described mounting groove (3a), be symmetrically fixed with guide-localization brace panel (6), on this guide-localization brace panel (6), have " ∩ " shape locating notch (6a), the two ends of described rubber bush assembly (2) are arranged in the locating notch (6a) of corresponding guide-localization brace panel (6), bolt (5) is through the mounting hole on mounting groove (3a) and the centre hole of rubber bush assembly (2), rubber bush assembly (2) and body component (3) are fixed together.
The present invention sets up two symmetrical guide-localization brace panels in the mounting groove of body component, in fitting process, " ∩ " shape locating notch of this guide-localization brace panel play the guiding role to the rubber bush assembly on trailing arm, so only the two ends of rubber bush assembly need be pushed from bottom to top from " ∩ " shape locating notch of corresponding guide-localization brace panel respectively, not only simply but also convenient; In the time being seated, guide-localization brace panel plays the role of positioning, and naturally also by the central aperture of the mounting hole on body component mounting groove and rubber bush assembly, so that bolt wears, has simplified the problem of follow-up assembling contraposition difficulty, has improved efficiency of assembling; And after fitting process completes, the end of rear torsion beam rubber bush assembly is positioned at guide-localization brace panel, guarantee that rear torsion beam rubber bush assembly presents state of nature after fastening, not preloading power effect, the service life of having guaranteed rubber bush assembly from assembly technology.Moreover, guide-localization brace panel has increased body component mounting groove installs the thickness of contact surface, has improved the intensity of rear torsion beam trailing arm attachment point, can effectively prevent body component after torsion beam trailing arm attachment point deform or damage.
In order to facilitate selection, guarantee product strength, simplify manufacture craft, save production cost, described guide-localization brace panel (6) is by the moulding of steel plate stamping, and thickness is 1.5-2mm.
Described guide-localization brace panel (6) is arch-shaped, and moulding is simple like this, and not only processing and fabricating is easy, and can effectively reduce material usage.
The opening part of described locating notch (6a) lower end is provided with "eight" shape targeting port (6b), and the wall of locating notch (6a) extends vertically, forms flange (6c).The lower port of locating notch is round and smooth enlarging, in the time of assembling, can make rubber bush assembly enter fast in locating notch; Flange the structural strength that has increased on the one hand guide-localization brace panel is set, on the other hand, can increase the contact surface of rubber bush assembly and guide-localization brace panel, make the better reliability of guide-localization.
In order to increase the fastness of connection, and simplify production technology, described guide-localization brace panel (6) is fitted and is welded on the cell wall of mounting groove (3a).
Beneficial effect: the present invention, by setting up guide-localization brace panel, can play the effect of guiding, location in the fitting process of rear torsion beam trailing arm, makes assembly manipulation simpler, convenient, and has effectively improved efficiency of assembling; After assembling completes, after guaranteeing, torsion beam rubber bush assembly is state of nature, the service life of having guaranteed rubber bush assembly from assembly technology.
