For 90 °.
Further, middle back bush includes middle back bush inner sleeve, middle back bush outer tube and is arranged in middle back bush
Middle back bush rubber layer between sleeve pipe, middle back bush outer tube.
Further, a circle arc groove is provided with the middle part of middle back bush rubber layer both ends of the surface.
The beneficial effects of the utility model are：Its stress and peace can not only be met by designing the LL body of such a structure
The requirement of holding position, and simple in construction, weight is light and handy, is easily installed.LL body is the one integral piece of integrated punching shaping,
Reduce procedure, improve production efficiency.All architectural features can process in place thereon, greatly increase finished product
Rate.Its intensity and rigidity will be stronger than the LL body being process using wrap direction, so as to improve the driving of automobile
Stability and drive safety.
Set with anterior cannula, two middle after sleeve welds on LL body and be in and sleeve pipe, middle rear enclosure tube outer surface
Corresponding cambered surface, it so can farthest reduce the gap between welded part after welding, its gap can even be reduced
It is zero, this mode can greatly improve the uniformity of LL assembly, so as to improve its rigidity and intensity.
Different according to the stress of two kinds of bushings, its rubber layer segment headspace shapes and sizes is also different, both meets
Rubber layer has enough deformation spaces when being squeezed, and will not cause rubber layer deformation failure because of space is too small again.

Embodiment
Specific embodiment of the present utility model is described below, in order to which those skilled in the art understand
The utility model, it should be apparent that the utility model is not limited to the scope of embodiment, to the common skill of the art
For art personnel, if various change in the spirit and scope of the present utility model that appended claim limits and determines,
These changes are it will be apparent that all utilize the innovation and creation of the utility model design in the row of protection.
As shown in Figure 1 and Figure 2, the utility model provides a kind of automobile longitudinal swing arm assembly, and it includes LL body
1st, it is welded on the left end of LL body 1 and inside is provided with the front sleeve 2 of front lining 3 and two inside are respectively arranged with
The middle after sleeve 4 of middle back bush 5, two middle after sleeves 4 be respectively welded at LL body 1 right-hand member and bottom surface from right-hand member six
/ mono- total strong point.
LL body 1 is molded using individual layer carbon steel sheet using mould integrated punching, and it is shaped as top surface and set to both sides
The Baltimore groove 11 of extension 12 is equipped with, as shown in figure 3, the inner width of Baltimore groove 11 from left to right gradually increases, LL body 1
The width of the extension 12 in stage casing is more than the width of the extension 12 at the both ends of LL body 1, the top surface of LL body 1
It is made up of bevel phase 13 and arc section 14, the junction of bevel phase 13 and arc section 14 seamlessly transits.
After the punch forming of LL body 1, the weld of 2, two middle after sleeves 4 of itself and front sleeve, which is set, is in and protheca
Cylinder 2, the cambered surface that is engaged of the outer surface of middle after sleeve 4, this cambered surface need to use the processing mode of milling to process, and the cambered surface at both ends is equal to pair
