Description
Technical Field
The utility model relates to an automobile engine part technical field specifically is a left side suspension support arm.
Background
With the rapid development of automobile technology, people have higher and higher performance requirements on various aspects of automobiles, the vibration and noise of the automobiles, which are one of the performance indexes of the automobiles, are more and more prominent, the mass consumption is gradually rationalized, and the low oil consumption and the good comfort are required for the purchase concept of the automobiles. In order to adapt to the changing trend of the market, the light weight which can meet the requirements of vehicle shock absorption, noise reduction and strength and simultaneously reduce the self weight of the vehicle is the current development direction. The engine left suspension is positioned on the left side of the power assembly, and plays a role in connecting and fixing the power assembly and isolating vibration transmission between the power assembly and a vehicle body. The left suspension assembly of the engine generally comprises a connecting support arm, a left suspension rubber main spring component and a support, wherein the existing suspension support arm is generally cast iron/cast aluminum, the existing suspension support arm is connected with the suspension assembly in a press-fitting and buckling connection mode, the weight is heavy, the process is complex, and when the support arm is made of other materials such as plastics, the strength of the support arm is difficult to guarantee.
Disclosure of Invention
In order to solve the problem that current left suspension support arm weight is heavy, the utility model provides a left suspension support arm, it can reduce product weight, ensures the intensity of product.
The technical scheme is as follows: the utility model provides a left side suspension support arm, its includes the support arm body, the support arm body includes grafting portion and connecting portion, its characterized in that, grafting portion with connecting portion are integrated into one piece's PA66+ GF50 working of plastics, be provided with metal insert on the connecting portion, the deep hole has been seted up to the tip of grafting portion, the lateral wall of deep hole forms the rib, the hole bottom of deep hole is deepened inside the connecting portion.
The rib is further characterized in that eight deep holes are formed, and the ribs are shaped like a Chinese character 'mi';
the outer wall of the insertion part is formed by folded surfaces, and the surface of the insertion part is a rough surface.
Adopt the utility model discloses afterwards, replace the support arm body for PA66+ GF50 working of plastics, reduced weight, set up the deep hole simultaneously, increased product strength when further reducing weight, the deep hole is deep into grafting portion for the easy cracked problem of grafting portion and connecting portion junction is solved originally, has further increased product strength.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an exploded view of the present invention;
fig. 3 is a cross-sectional view of the present invention.
Detailed Description
Referring to fig. 1, 2 and 3, the left suspension support arm comprises a support arm body 1, wherein the support arm body 1 comprises a plugging part 2 and a connecting part 3, the plugging part 2 and the connecting part 3 are integrally formed PA66+ GF50 plastic pieces, a metal insert 4 is arranged on the connecting part 3, a deep hole 5 is formed at the end part of the plugging part 2, ribs 6 are formed on the side wall of the deep hole 5, the bottom of the deep hole 5 extends into the connecting part 3, and the deep hole 5 can meet the vulcanization process of the support arm and a rubber main spring. On the other hand, the support arm is further lightened, the formed ribs 6 increase the strength of the product, the connection part 2 and the connecting part 3 is fragile, and the deep hole 5 extends into the connecting part 3, so that the weak point can be avoided, and the strength of the product is further increased. In this embodiment, the deep hole 5 has specifically been seted up eight, and rib 6 becomes the meter font for 2 all directions of grafting portion all have the support, and intensity is promoted.
The outer wall of the insertion part 2 is formed by a folded surface, and the surface of the outer wall is a rough surface, so that the binding force between the outer wall and the main spring assembly is increased, and the outer wall and the main spring assembly are more stable and reliable.
Claims (3)
1. The utility model provides a left side suspension support arm, its includes the support arm body, the support arm body includes grafting portion and connecting portion, its characterized in that, grafting portion with connecting portion are integrated into one piece's PA66+ GF50 working of plastics, be provided with metal insert on the connecting portion, the deep hole has been seted up to the tip of grafting portion, the lateral wall of deep hole forms the rib, the hole bottom of deep hole is deepened inside the connecting portion.
2. The left suspension arm according to claim 1, wherein eight deep holes are formed in the left suspension arm, and the ribs are in a shape like a Chinese character 'mi'.
