Description

Technical Field

[0001] The utility model discloses a V-shaped thrust rod connecting shaft, belonging to an automobile accessory. Background Art

[0002] The V-shaped thrust rod connecting shaft of the car is used to prevent the front and rear shifts of the center and rear axles and the left and right shifts. When the car body rolls, the suspensions on both sides will jump inconsistently, and the lateral thrust rod will twist. The elastic force of the rod body will become a resistance to the continued roll of the car, and finally play a role in lateral stability. Therefore, during the driving process of the vehicle, especially when the car body rolls, the thrust rod connecting shaft is subjected to torque such as torsion and yaw. Therefore, for the thrust rod connecting shaft, it is necessary to ensure its strength and a certain degree of flexibility. In order to prevent the ball head of the connecting shaft from hard collision with its outer ball bowl, the outer surface of the ball head is generally made of nylon material. In actual use, it is very easy to be worn, resulting in an incomplete ball. Once the gap is formed, it will accelerate the damage of the ball head, which not only reduces its service life, but also increases the risk during vehicle driving. Summary of the invention

[0003] The utility model aims to design a V-shaped thrust rod connecting shaft with high strength and good wear resistance.

[0004] The utility model is composed of a shaft body and a nylon body fixedly connected to the shaft body, the shaft body comprises connecting parts at both ends thereof and a circular shaft part between the connecting parts, a reinforcing plate integrated with the shaft body is arranged on the circular shaft part, the nylon body is arranged on both sides of the reinforcing plate, the outer surface of the nylon body and the outer surface of the reinforcing plate are smoothly transitioned and together form a spherical surface.

[0005] Furthermore, both sides of the reinforcing plate are planes or conical surfaces with the circular shaft portion as the central part, and the two surfaces are connected to the surface of the circular shaft portion through an arc-shaped concave surface.

[0006] Furthermore, two side surfaces of the reinforcing plate are planes perpendicular to the axis of the circular shaft portion.

[0007] Furthermore, the reinforcing plate is a part of a sphere; at the midpoint of the axis of the circular shaft, the diameter of the first cross section of the reinforcing plate perpendicular to the axis of the circular shaft is the same as the diameter of the sphere.

[0008] Furthermore, two side surfaces of the reinforcing plate are perpendicular to the plane, and the distances from the two side surfaces to the first cross section are the same.

[0009] The utility model not only ensures the flexibility of the ball head part composed of the reinforcing plate and the nylon body, but also ensures the rigidity of the ball head, thereby ensuring its strength and wear resistance, enhancing its force bearing capacity, and thus improving the safety of vehicle driving. In particular, after the installation of this embodiment, the ball head part cooperates with the ball bowl part of the thrust rod bearing. Since the position of the ball head part in the ball bowl is constantly adjusted during the driving of the vehicle, the utility model applies force to the ball bowl more evenly as a whole, thereby also reducing the damage of the rigid part to the ball bowl part as much as possible, thereby extending the service life of the thrust rod assembly as much as possible on the basis of improving the driving safety performance of the vehicle.

[0013] Unless otherwise specified, the directions of up, down, left, right, front, back, inside and outside in this application document are all based on the directions shown in this embodiment. Figure 1 The directions of the product shown in the figure shall prevail, including the directions of up, down, left, right, front, back, inside and outside. The actual processing errors are not considered in this application document.

[0014] As shown in the figure, this embodiment includes a shaft body and a nylon body fixed on the shaft body.

[0015] The shaft body of this embodiment includes right connecting parts 1 and 6 at both ends thereof and a circular shaft part 2 between the left and right connecting parts, and a reinforcing plate 4 is arranged in the middle of the circular shaft part 2. The connecting part 1, the circular shaft part 2 and the reinforcing plate 4 are an integrated structure.

[0016] The connecting parts 1 at both ends of this embodiment are in the shape of flat plates, and the connecting parts 1 at both ends are located on the same plane. Each connecting part 1 is provided with two front and rear mounting holes for connecting with an external structure.

[0017] The circular shaft portion 2 is cylindrical, and the reinforcing plate 4 is arranged in the middle of the circular shaft portion 2, that is, at the midpoint of its axis and around it. The peripheral surface of the reinforcing plate 4 is a spherical surface, that is, the reinforcing plate 4 is a part of a sphere. Let the cross section perpendicular to the axis of the circular shaft portion 2 at the midpoint of the axis of the circular shaft portion 2 be the first cross section, then the diameter of the first cross section is the same as the diameter of the sphere, that is, the first cross section is the maximum cross section of the reinforcing plate 4. The position 7 of the first cross section is shown in the figure.

[0018] The two side surfaces of the reinforcing plate 4 can be in different shapes, such as different concave and convex surfaces, flat surfaces or curved surfaces, or a conical surface with the circular shaft portion as the central part, etc. However, due to the strength requirements, the continuous part of the reinforcing plate 4 and the circular shaft body 2 should be connected with an arc-shaped concave surface to disperse the stress there.

[0019] For the convenience of processing, the two side surfaces of the reinforcing plate 4 are generally processed into planes, and the two side surfaces can be in any inclined direction. Generally, the two side surfaces of the reinforcing plate 4 are perpendicular to the axis of the circular shaft portion 2, and have the same distance to the first cross section.

[0020] In this embodiment, a left nylon body 3 and a right nylon body 6 are fixed to both sides of the reinforcing plate 4, respectively. The outer surfaces of the two nylon bodies are both spherical surfaces, and their outer surfaces smoothly transition with the outer surface of the reinforcing plate 4 and together form a spherical surface.
