Description

Technical Field

[0001] The utility model relates to the technical field of V-shaped thrust rods, in particular to an aluminum alloy V-shaped thrust rod. Background Technique

[0002] As an important component of large vehicles, the V-shaped thrust rod can effectively prevent the front, rear, left, and right offsets of the middle and rear axles of the chassis, ensuring that the vehicle is not prone to rollover during high-speed turning. However, with the rise of lightweighting, the V-shaped thrust rod has gradually changed from a rigid material to an aluminum alloy material to achieve the purpose of lightweighting. In the prior art, the thrust rod can be divided into two types: integral type and split type. The integral type is integrally formed by forging and casting methods. However, usually, if one part is damaged, the whole cannot be used, and the cost will be greatly increased. The split type uses a connecting rod and a ball head to be cast separately and then connected by thread rotation. When a component is damaged, it can be replaced in time, reducing the use cost. However, due to the use of thread rotation connection, the lengths of the connecting rod and the ball seat will be different due to different numbers of rotations during connection. Each time of replacement requires using a tape measure to record the old size to determine the length of the new size, which greatly increases the replacement time and also increases the labor cost.

[0003] Generally, the damage of the components of the V-shaped thrust rod is caused by the rubber in the ball seat being damaged or cracked, resulting in the ball pin not being fixed. Since the two ends of the V-shaped thrust rod are the places where the force is the greatest, not only the transverse force and longitudinal force but also the relevant lateral force and torsional force are applied here, resulting in uneven force on the ball pin and damage. Therefore, it is necessary to design a new aluminum alloy V-shaped thrust rod that can improve the connection method and increase the force-bearing situation in view of the shortcomings of the prior art. Content of the Utility Model

[0004] The purpose of the utility model is to provide an aluminum alloy V-shaped thrust rod to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an aluminum alloy V-shaped thrust rod, including a V-shaped rod head, two connecting rods, and three ball seats. It is characterized in that: a ball seat is arranged below the V-shaped rod head, and a connecting column is arranged above the left and right of the V-shaped rod head. One end of the two connecting columns is connected to the two connecting rods. Grooves are opened at the upper ends of the two connecting columns. Two symmetrically protruding semi-circular plates are arranged in the grooves, and through holes are opened below the two semi-circular plates. Circular working grooves are respectively opened at both ends of the connecting rod, and the circular working grooves are matched with the semi-circular plates on the connecting column. Two symmetric threaded grooves are opened on the connecting rod, and the threaded grooves communicate with the through holes on the connecting column. The threaded grooves and the through holes are fixedly connected by fastening bolts. The other ends of the two connecting rods are also connected by connecting columns, and a ball seat is respectively arranged at the other ends of the two connecting columns.

[0006] Preferably, the depth of the circular working groove is the same as the depth of the semi-circular plate protrusion, and the through hole and the threaded groove are communicated with each other under rotational fit.

[0007] Preferably, the wall thickness of the groove formed on the connecting column is the same as the thickness of the two ends of the connecting rod after turning, and the depth of the groove is the same as the length of the circular working groove.

[0008] Preferably, ball pins are arranged in the three ball seats, and four threaded holes are respectively arranged at both ends of the ball pins extending out of the ball seats for fixing.

[0009] Preferably, lower snap rings are arranged on the four sides inside the ball seat, and the lower snap rings are fixed on the inner wall of the ball seat. A spring is sleeved on the upper end of the lower snap ring, and the other end of the spring is connected to the upper snap ring. The upper snap ring is fixed at both ends of the ball pin.

[0010] Preferably, the upper end of the upper snap ring is semi-circular, and a plurality of long convex strips are arranged inside the semi-circular shape.

[0011] Preferably, long grooves are formed at both ends of the ball pin inside the ball seat and are matched with the long convex strips at the upper end of the upper snap ring.

[0012] Preferably, anti-rotation rubber is arranged around the ball pin inside the ball seat to increase the frictional resistance around the ball pin.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By using the semi-circular plate protrusion on the connecting column to rotatably engage with the circular working groove formed on the connecting rod, the connection strength is increased. Two symmetrical through holes and threaded grooves are respectively formed on the connecting column and the connecting rod, and the connection is strengthened by a fastening bolt, realizing a connection method with high connection strength, easy assembly and disassembly, reducing the replacement time and also reducing the labor cost.

[0015] 2. By using the plurality of long convex strips inside the semi-circular shape at the upper end of the upper snap ring to be snap-connected with the long grooves at both ends of the ball tip, and arranging anti-rotation rubber around the ball tip to increase the frictional resistance of the ball tip, and four bolt holes are respectively formed at both ends of the ball tip extending out of the ball seat to strengthen the connection of the ball tip, so that the ball tip remains fastened under the pressure of various forces, and it also prevents the rubber from being damaged or cracked due to uneven force of the ball tip in the ball seat, thereby increasing the safety during use and also reducing the production cost.
