For logical technical staff, concrete meaning of the above-mentioned term in the utility model can be understood with concrete condition.
One end of back lower controlling arm 100 can be connected with subframe, and the other end of back lower controlling arm 100 can be with knuckle
It is connected, and back lower controlling arm 100 can be used for installing spring.
Back lower controlling arm 100 below with reference to Fig. 1-Fig. 8 descriptions according to the utility model embodiment, as Figure 1-Figure 8,
Include first 1 and second 2 according to the back lower controlling arm 100 of the utility model embodiment.
As shown in Figure 1-Figure 3, second 2 lower section for being located at first 1, back lower controlling arm 100 uses to be set on above-below direction
The two-piece type structure put, reduce the manufacture difficulty of back lower controlling arm 100.
It is connected as shown in Fig. 2 two sides of second 2 are corresponding with two sides of first 1, is respectively left side with two sides
Exemplified by side and right edge, the left side of first 1 is connected with the left side of second 2, the right edge of first 1 with second 2
Right edge be connected.Can so make first 1 it is more firm with the connection of second 2.
As shown in Figures 2 and 3, the middle part of first 1 is provided with the first sleeve 11 being downwardly concaved, and the middle part of second 2 is set
There is upwardly recessed second sleeve 21, the first sleeve 11 is corresponding with second sleeve 21 to be connected, such as the first sleeve 11 and second set
Cylinder 21 can be arranged connected, i.e. the part that the part of second sleeve 21 is set in the first sleeve 11 is outer.The He of first sleeve 11
Second sleeve 21, which is connected, forms a spring tray, and for support spring, i.e. spring tray is integrated in back lower controlling arm 100
Portion, thus the bending strength at the middle part of back lower controlling arm 100 is high.
Alternatively, as shown in Figure 5 and Figure 6, there are spring locating features 111 on the first sleeve 11, set spring to position knot
Structure 111 can ensure that spring is effectively positioned at work, and can lift the structural strength at the middle part of first 1.
Alternatively, as shown in Fig. 2 the diameter of the first sleeve 11 reduces from the top down, and a stage portion is formed, thus tied
Structure intensity is higher, easy to manufacture, is easily installed spring, and is easy to be connected with second sleeve 21.
According to the back lower controlling arm 100 of the utility model embodiment, it is respectively equipped with first 1 and second 2 towards that
The first sleeve 11 and second sleeve 21 of this extension, to form spring tray, i.e., the first sleeve 11 is connected with second sleeve 21
By the depth of spring tray share first 1 and second 2 on, the depth of such first sleeve 11 and second sleeve 21 is (long
Degree) it is smaller, during stamped first 1 and second 2, the reduction of the material of first 1 and second 2 reduces, indirectly
Bending strength is improved, and the first sleeve 11 and the anufacturability of second sleeve 21 are good, and Joining Technology is good.
As shown in Figure 1-Figure 3, two sides of first 1 correspond to two sides of second 2 and are connected, and the He of the first sleeve 11
Second sleeve 21 is connected, so that back lower controlling arm 100 limits cavity 101 between first 1, second 2.It can manage
Solution, back lower controlling arm 100 in the course of the work, is primarily subjected to side force, by the connection of first 1 and second 2 and
Structure is improved, and the cavity 101 of above-mentioned sealing is formed at the middle part of back lower controlling arm 100, can effectively lift back lower controlling arm 100
Bending strength and energy-absorbing effect, particularly can effectively lift the bending strength at the middle part of back lower controlling arm 100.
