Structure.
Preferably, the end of the lower swing arm is equipped with the bushing for connecting with automobile frame.
Preferably, the lower swing arm is equipped with the first stiffening plate between the part of the bushing.
Preferably, first stiffening plate includes reinforcing shell to reinforce ontology with the intracorporal frame-type of stiffened shell is set to,
It is the honeycomb structure being formed by connecting by several second reinforcing ribs that the frame-type, which reinforces ontology, and the frame-type reinforces ontology
Place plane is perpendicular to plane where the frame-type ontology.
Preferably, the mounting portion is equipped with mounting bracket of shock absorber.
It preferably, further include the second stiffening plate of the insertion ring equipped with regular hexagon, the mounting portion is equipped with for described
The through-hole of insertion ring insertion, second stiffening plate are steel stiffening plate, and the mounting portion is aluminium alloy plate.
Preferably, the shell is Al-alloy casing, and the reinforcing rib is steel reinforcing rib.
Preferably, the lower swing arm and mounting portion are integrally formed.
Preferably, it is integrally formed by forging between the shell and reinforcing rib, between several reinforcing ribs.
Preferably, second stiffening plate is welded in the mounting portion.
Beneficial effects of the present invention:
Ontology using the honeycomb structure of reinforcing rib composition as lower swing arm, passes through honeycomb while reducing lower swing arm weight
Shape structure guarantees, improves lower swing arm intensity.

Specific embodiment
It is a specific embodiment of the invention below, and in conjunction with attached drawing, technical solution of the present invention work is further retouched
It states, however, the present invention is not limited to these examples.
A kind of automobile lower suspension arm assembly, as shown in Figure 1, including at least two lower swing arms 10, one end of two lower swing arms 10
It is crossed to form the mounting portion 20 for being equipped with the ball pin component 21 for connecting with spindle, wherein in order to improve entire automobile
The intensity of lower swing arm, lower swing arm 10 and mounting portion 20 can use integrally formed forging method.
Lower swing arm 10 includes shell 11 and is set to the intracorporal frame-type ontology 12 of shell, and frame-type ontology 12 includes several adds
Strengthening tendons 12a, one end of a reinforcing rib 12a is connect respectively with 120 ° of angles with one end of other two reinforcing ribs 12a, so that frame
Formula ontology 12 forms honeycomb structure.
Honeycomb structure makes frame-type ontology 12 with the through-hole of many regular hexagons, to reduce making for material
With decreasing the weight of lower swing arm 10.Simultaneously as the both ends of every reinforcing rib 12a are connected separately in honeycomb structure
Two reinforcing rib 12a have the characteristics that intensity is high so as to disperse power suffered by lower swing arm 10 well.
In addition, the end of lower swing arm 10 is equipped with the bushing 13 for connecting with automobile frame.Mounting portion 20 is equipped with damper
Mounting bracket 22.
In order to further increase the Lower Sway Arm of Automobile intensity, lower swing arm 10 is equipped with first between the part of bushing 13 and adds
Strong plate 14 can be avoided automobile the Lower Sway Arm of Automobile in starting, braking and turning and deform, improves automobile steering roller positioning and turn
To performance, roadability and safety are improved.
While in order to mitigate the weight of the first stiffening plate 14, the first stiffening plate 14 includes reinforcing shell 14a and being set to add
Frame-type in strong shell 14a reinforces ontology 14b, and frame-type reinforces ontology 14b and is formed by connecting by several second reinforcing ribs
Honeycomb structure, and frame-type reinforces the place ontology 14b plane perpendicular to 12 place plane of frame-type ontology.Equally pass through honeycomb
Shape structure achievees the effect that intensity height, light weight.
Further, as shown in Fig. 2, further including the second stiffening plate 30 of the insertion ring 31 equipped with regular hexagon, installation
Portion 20 is equipped with the through-hole 23 being embedded in for insertion ring 31, and the second stiffening plate 30 is steel stiffening plate, and mounting portion 20 is aluminium alloy plate.
And second stiffening plate 30 be welded in mounting portion 20.Aluminium alloy plate has the advantages that light-weight, and steel stiffening plate has intensity high
The advantages of, the two complements each other, and further enhances the Lower Sway Arm of Automobile intensity.
Likewise, shell 11 can also be designed as Al-alloy casing by lower swing arm 10, reinforcing rib 12a is designed as steel reinforcement
Muscle.And it is integrally formed by forging between shell 11 and reinforcing rib 12a, between several reinforcing rib 12a.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
