Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a stamped triangular arm assembly with high load-bearing capacity. Background Technology

[0002] Triangular arm assemblies are automotive suspension components that serve to cushion, dampen vibrations, and transmit force. For example, Chinese patent literature discloses a triangular arm assembly [Application No.: 202322171044.8; Authorization Announcement No.: CN220809051U], which includes an arm body. A ball joint assembly is connected to the upper end of the arm body, and rubber sleeve assemblies are connected to both ends of the arm body. The rubber sleeve assembly includes an inner tube, an outer tube, and an elastic body. The elastic body is fixed between the inner tube and the outer tube. The inner end of the elastic body has a first buffer groove recessed along the axial direction of the rubber sleeve assembly, and the outer end has a second buffer groove recessed along the axial direction of the rubber sleeve assembly. The groove walls on both sides of the first and second buffer grooves are respectively fitted and fixed to the inner tube and the outer tube.

[0003] The aforementioned control arm assembly has the advantage of good cushioning effect, but the connection stability between the upper control arm and the ball joint is poor and lacks reinforcement structure. As the vehicle is affected by various complex road conditions and load changes during driving, the control arm and the ball joint are prone to shaking, which will affect the stability and comfort of the vehicle. At the same time, it is not convenient to lubricate the ball joint and the control arm, which can easily cause wear and damage between the parts and reduce the service life of the control arm assembly. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a stamped triangular arm assembly that provides reinforced support between the triangular arm and the ball joint, resulting in high stability, long service life, and strong load-bearing capacity.

[0005] The objective of this utility model can be achieved through the following technical solution: a high-load-bearing stamped triangular arm assembly, comprising a triangular plate body, a support tube penetrating the surface of the triangular plate body, a bottom cover penetrating the bottom of the support tube, a support seat provided in the inner cavity of the support tube, a ball joint assembly penetrating the top of the support seat, a dust cover fitted on the top of the support seat, a lubricating oil filling pipe penetrating the surface of the dust cover, a sealing cap fitted on the top of the lubricating oil filling pipe, and a reinforcing mechanism installed at the bottom of the triangular plate body, the reinforcing mechanism comprising a reinforcing plate and a mounting plate.

[0006] By incorporating support tubes, bottom covers, support seats, ball joint assemblies, dust covers, reinforcing plates, and mounting plates, the ball joint assembly can be stably supported. The support tubes provide installation space and protection for internal components, while the support seats play a crucial supporting role, effectively distributing and bearing various loads from vehicle operation. This significantly improves the overall load-bearing capacity of the control arm assembly, enabling it to adapt to high-load conditions and extending its service life. The dust cover, lubrication oil filling pipe, and sealing cap facilitate the addition of lubricating oil to the bottom of the ball joint assembly via an external injection pipe, reducing friction and wear between components and ensuring the normal operation of the ball joint assembly. Simultaneously, it effectively prevents dust and impurities from entering, ensuring cleanliness of the lubrication points and reducing maintenance costs.

[0007] In the aforementioned high-load-bearing stamped triangular arm assembly, a shock-absorbing sleeve is fitted onto the surface of the support base, and the outer surface of the shock-absorbing sleeve contacts the inner wall of the support tube. By installing the shock-absorbing sleeve, when the vehicle is subjected to vibration and impact during operation, the shock-absorbing sleeve can absorb and buffer some of the energy, reduce the impact of vibration on the support base and ball joint assembly components, reduce the risk of wear and damage between components, and extend the service life of the triangular arm assembly.

[0008] In the aforementioned high-load-bearing stamped triangular arm assembly, the top of the reinforcing plate contacts the bottom of the bottom cover, one side of the reinforcing plate is fixedly connected to the mounting plate, and a threaded rod is fixedly connected to the bottom of the triangular plate body, with a first nut threaded onto the surface of the threaded rod. By setting the reinforcing plate and mounting plate, the structural strength of the bottom of the connection between the triangular plate body and the ball joint assembly is enhanced, enabling the triangular arm assembly to remain stable under large loads, preventing deformation or damage, and improving load-bearing capacity and reliability.

[0009] In the aforementioned high-load-bearing stamped triangular arm assembly, a support shell is provided at the bottom of the ball joint assembly, and a support block is provided at the bottom of the support shell. The support block is located at the bottom of the inner cavity of the support seat. By providing the support shell and support block, a more stable and reliable support is provided for the ball joint assembly. The support shell and support block can evenly transfer the load on the ball joint assembly to the support seat, reducing stress concentration between the ball joint assembly and the support seat, and lowering the risk of damage to the ball joint assembly.

[0010] In the aforementioned high-load-bearing stamped triangular arm assembly, a locking ring is fitted onto the surface of the dust cover, a bolt is connected through the surface of the locking ring, and a second nut is fixedly connected to the surface of the locking ring. By setting the locking ring and bolt, the dust cover can be tightly fitted onto the support base, preventing the dust cover from loosening or falling off during use, thus ensuring the dustproof effect of the dust cover.

[0011] In the aforementioned high-load-bearing stamped triangular arm assembly, one end of the bolt passes through both the locking ring and the second bolt, and the bolt is threadedly connected to the second nut. By using the bolt and the second nut, the fixing and disassembly of the locking ring becomes more convenient, facilitating the inspection, replacement, and maintenance of the dust cover when needed. After removing the bolt, the dust cover separates from the support seat, making it easier to add solid lubricating oil to the ball joint assembly, achieving long-term lubrication of the ball joint assembly.

[0012] Compared with existing technologies, the advantages of this high-load-bearing stamped triangular arm assembly are as follows: the support tube provides installation space and protection for internal components; the support seat plays a key supporting role for the ball joint assembly, effectively distributing and bearing various loads from vehicle operation, significantly improving the overall load-bearing capacity of the triangular arm assembly, enabling it to adapt to high-load working conditions, extending its service life, facilitating the addition of lubricating oil to the bottom of the ball joint assembly using an external injection tube, reducing friction and wear between components, ensuring the normal operation of the ball joint assembly, and effectively preventing dust and impurities from entering, ensuring the cleanliness of the lubrication points, and reducing maintenance costs.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, this high-load-bearing stamped triangular arm assembly includes a triangular plate body 1, a support tube 2 that is connected through the surface of the triangular plate body 1, a bottom cover 3 that is connected through the bottom of the support tube 2, a support seat 4 that is provided in the inner cavity of the support tube 2, a ball head assembly 5 that is connected through the top of the support seat 4, a dust cover 6 that is fitted on the top of the support seat 4, a lubricating oil filling pipe 7 that is connected through the surface of the dust cover 6, a sealing cover 8 that is fitted on the top of the lubricating oil filling pipe 7, and a reinforcing mechanism 9 that is installed at the bottom of the triangular plate body 1. The reinforcing mechanism 9 includes a reinforcing plate 90 and a mounting plate 91.

[0019] To elaborate further, a shock-absorbing sleeve 15 is fitted onto the surface of the support base 4, and the outer surface of the shock-absorbing sleeve 15 contacts the inner wall of the support tube 2. The top of the reinforcing plate 90 contacts the bottom of the bottom cover 3, one side of the reinforcing plate 90 is fixedly connected to the mounting plate 91, and a threaded rod 93 is fixedly connected to the bottom of the triangular plate body 1, with a first nut 92 threaded onto the surface of the threaded rod 93.

[0020] In actual manufacturing, a support shell 10 is provided at the bottom of the ball head assembly 5, and a support block 11 is provided at the bottom of the support shell 10. The support block 11 is located at the bottom of the inner cavity of the support base 4. A locking ring 12 is fitted on the surface of the dust cover 6, and a bolt 13 is connected through the surface of the locking ring 12. A second nut 14 is fixedly connected to the surface of the locking ring 12. One end of the bolt 13 passes through the locking ring 12 and the second nut 14 respectively, and the bolt 13 is threadedly connected to the second nut 14.

[0021] In use, the ball joint assembly 5 is connected to the top of the support seat 4, so that the ball joint assembly 5 can be stably installed on the triangular plate body 1. Various forces and loads from the wheel are transmitted to the support seat 4 through the ball joint assembly 5. The support seat 4 then evenly distributes the load to the support tube 2, and finally transmits it to the triangular plate body 1. When the vehicle is subjected to vibration and impact during driving, the vibration energy will be transmitted to the support seat 4 through the ball joint assembly 5, and then act on the shock absorber sleeve 15. The shock absorber sleeve 15 uses its own elastic properties to absorb and buffer part of the vibration energy, reducing the impact of vibration on the support seat 4, ball joint assembly 5 and other components. The reinforcing plate 90 reinforces and supports the bottom of the bottom cover 3. Rotating the first nut 92 separates it from the threaded rod 93, and the bottom cover 3 can be disassembled. By tightening the bolt 13, the locking ring 12 is tightly fitted onto the dust cover 6, and the dust cover 6 is tightly fitted onto the support seat 4, preventing the dust cover 6 from loosening or falling off during use. It can effectively prevent dust, mud and sand impurities from entering the ball joint assembly 5.
