Description
Technical Field
The utility model relates to a connecting rod field, in particular to split type compound lightweight connecting rod assembly.
Background
With the development of society, the exploitation and consumption of various energy sources, pollution has become a focus of global attention, so the requirement for exhaust emission is higher and higher in the face of increasing motor vehicles. To minimize exhaust pollution, the NVH of the vehicle must be considered.
In recent years, electric vehicles have emerged, but the current bottleneck of electric vehicle development is the cruising ability problem under the conditions of no mature infrastructure, no sufficiently fast charging mode and the like, and the light weight can significantly improve the cruising ability of the electric vehicle, so that the automobile enterprises have paid extensive attention to the problem.
Therefore, each large host factory starts to invest a lot of manpower, material resources and financial resources to meet the national requirements in the shortest time and quickly occupy the market, and the thrust rod therewith becomes a problem which is easiest to implement and solve at first.
However, if the composite material is applied to the thrust rod, the problem that the center distance is not adjustable during one-step forming is solved, the center distance refers to the distance between the axes of the center holes at the joints at the two ends of the rod body, and a set of special injection mold is needed for each product corresponding to one center distance, so that the mold investment is large, and further the product cost is difficult to reduce.
In addition, if the traditional press-fitting process is adopted to directly press the spherical hinge into the composite material joint, the problem of joint cracking can be caused, and a preparation method of the product is provided.
For example, patent 201510739066.7 discloses a method for reducing the weight of a thrust rod and a thrust rod with reduced weight, wherein a rod body is made of a polymer material and is formed in one step by an injection mold. The novel rod comprises a rod body, wherein the rod body comprises a rod body and connectors arranged at two ends of the rod body. Before the rod body is molded, two metal sleeves are respectively arranged in the inner cavities of two connectors of the rod body, so that after molding, the metal sleeves and the connectors are integrated, and the elastic spherical hinge is assembled in the inner cavity of the metal sleeve.
The lightweight thrust rod has the disadvantages that the length of the rod body is fixed, the center distance of a one-time molded product is single, the production of products with different center distances cannot be realized by a single set of die, and the investment on development dies of different products in the later period is very large.
In addition, because the distance between the centers of the thrust rods is long, and the integral polymer material injection molding process is adopted, the polymer composite material can be quickly solidified after precooling, so that the longer the flow distance of the polymer composite material is, the longer the time for the polymer to flow is, under the condition of a certain injection speed, the larger the risk of defective products caused by uneven flow and long flow distance of the polymer composite material exists.
Meanwhile, the injection molding product can not avoid the appearance of weld lines, the weld lines are the weak points of the mechanical property of the injection molding part, and the strength of the part can be greatly reduced. The integral polymer material thrust rod, if the injection port is set in the middle of the rod body, the weld line will appear at both ends of the joint.
In view of the above, those skilled in the art will appreciate that the structure of the connecting rod assembly may be modified to overcome the above-described problems.
