Description

Technical Field

[0001] This utility model relates to the field of automotive thrust rod technology, specifically an automotive thrust rod assembly. Background Technology

[0002] The thrust rod assembly is a key component of the chassis of heavy commercial vehicles. It is mainly used to connect the frame and the axle, transmit longitudinal and lateral forces, stabilize the axle position, and prevent displacement. Thrust rods include I-type and V-type.

[0003] However, while the V-shape increases the stability of the connection and provides uniform support for longitudinal and lateral forces, the V-shaped rods are prone to tensile deformation under the combined load of longitudinal traction and lateral centrifugal force. Furthermore, during maintenance, it is not possible to reduce resource waste by replacing damaged or unstable parts and minimizing material waste. Utility Model Content

[0004] The purpose of this invention is to provide an automotive thrust rod assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thrust rod assembly for automobiles includes a connecting seat and a V-shaped rod mounted on the connecting seat. The upper surface of the connecting seat is provided with a cross plate, and an arc-shaped groove is formed in the middle of the cross plate. Connecting grooves are formed at the top of both ends of the cross plate, and screw holes are formed at the bottom of the connecting grooves. A first ball seat is provided at the tip of the V-shaped rod, and a rotating first ball head is provided in the first ball seat. Second ball seats are provided at the other two ends of the V-shaped rod, and a rotating second ball head is provided in each of the second ball seats. A reinforcing rod is provided between the two sides of the V-shaped rod.

[0007] Furthermore, the bottom of the cross plate is welded and fixed to the upper surface of the connecting seat, and the upper surface of the connecting seat is provided with fixing holes near the four corners.

[0008] In this utility model, the opening of the fixing hole facilitates the passage of external bolts through the fixing hole and their fixing to the vehicle frame, thereby achieving the installation and fixing of the bottom of the connecting seat.

[0009] Specifically, the first ball seat and the V-shaped rod are integrally formed. The first ball seat has a first slot inside. The first ball head has a first retaining ring on the outer wall corresponding to the first slot. The first ball head has a first through hole at both ends. Each of the first through holes has a fixing bolt.

[0010] In this invention, the first retaining ring and the first retaining groove rotate to prevent the first ball head from dislodging from the first ball seat. The fixing bolt passes through the first through hole to facilitate threaded connection with the screw hole in the connecting groove, thereby realizing the combined installation of the end of the first ball head and the cross plate.

[0011] It should be noted that the width of the inner wall of the arc-shaped groove is adapted to the width of the outer wall of the first ball seat, the width of the inner wall of the connecting groove is adapted to the width of the outer wall at both ends of the first ball head, and the fixing bolt passes through the first through hole and is threadedly connected to the screw hole.

[0012] In this invention, the first ball seat is inserted into the arc-shaped groove, allowing the tip of the V-shaped rod to be inserted into the cross plate through the first ball seat. Under the action of the fixing bolt, the position is fixed. The fixing bolt is removed, allowing the first ball seat and the cross plate to be separated and disassembled and replaced separately, reducing the need for complete replacement and avoiding material waste.

[0013] Specifically, the second ball head and the side bar of the V-shaped rod are integrally formed. The inner wall of the second ball seat is provided with a second slot, and the outer wall of the second ball head is provided with a second retaining ring corresponding to the second slot. The two ends of the second ball head are provided with a second through hole.

[0014] In this invention, the second retaining ring is rotatably connected to the second retaining groove to prevent the second ball head from disengaging from the second ball seat. With the cooperation of the second through hole, it is convenient for external bolts to pass through the corresponding second through hole and be combined and fixed with the corresponding position of the car body, so that the frame can be connected to the car body through the V-shaped rod and the connecting seat.

[0015] Furthermore, both ends of the reinforcing rod are tightly fitted to the outer wall of the side rod of the V-shaped rod and welded to fix it.

[0016] In this invention, the reinforcing rod connects the two side rods of the V-shaped rod body, increasing the structural stability between the side rods, reducing the deformation of the V-shaped rod body under the combined action of longitudinal and lateral forces on the vehicle, increasing the resistance to compression or tensile force, and extending the service life.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting a connecting seat with a cross plate, allows the V-shaped rod to be inserted into the arc-shaped groove through the first ball seat, and the two ends of the first ball head to be inserted into the slot. With the help of the fixing bolt, the connecting seat and the V-shaped rod are combined and fixed, and the connecting seat is combined and fixed to the vehicle frame. The other two ends of the V-shaped rod are combined and fixed to the vehicle body through the second ball seat and the second ball head, stabilizing the position of the vehicle body and reducing the impact of displacement damage. The connecting seat and the V-shaped rod can be disassembled and separated by the fixing bolt, which is convenient for individual disassembly and replacement, and reduces the material waste caused by overall replacement.

[0019] 2. This utility model increases the resistance of the V-shaped rod to compression or tensile deformation by setting a reinforcing rod to connect the two side rods of the V-shaped rod body, thereby extending the overall service life. The first ball head rotates flexibly in the first ball seat with the cooperation of the first retaining ring, and the second ball head rotates flexibly in the second ball seat with the cooperation of the second retaining ring, which facilitates the connection and fixation of the frame and the car body.
