Description

Technical Field

[0001] This utility model relates to the field of automotive suspension technology, specifically a high-load control arm. Background Technology

[0002] As a guiding and force-transmitting element of the automotive suspension system, the control arm transmits various forces acting on the wheels to the vehicle body, while ensuring that the wheels move along a specific trajectory. The control arm elastically connects the wheels and the vehicle body via ball joints or bushings. The control arm (including the connected bushings and ball joints) should have sufficient rigidity, strength, and service life. The suspension system refers to the entire support system composed of springs and shock absorbers between the vehicle body and the tires. The function of the suspension system is to support the vehicle body and improve ride comfort; different suspension settings will give the driver different driving experiences. The seemingly simple suspension system integrates multiple forces and determines the stability, comfort, and safety of a car, making it one of the most critical components of modern automobiles. Most existing automotive control arms are connected to the suspension links, which are prone to damage due to prolonged vehicle operation and exposure to different terrains. To address this issue, a high-load control arm is proposed to solve the aforementioned problems.

[0003] Application number 201620703850.2 discloses a control arm assembly, including an arm body. One end of the arm body has a first bushing, and the other end has a second bushing. The first bushing includes a first spindle with a spherical protrusion in the center. A ball seat is fitted over the spherical protrusion, and a first welded component is fitted over the ball seat. The first welded component is welded to one end of the arm body. The second bushing includes a second spindle with an elastic ring fitted over it. The ring is embedded in a fixed ring, and a second welded component is fitted over the fixed ring. The second welded component is welded to the other end of the arm body. Through the ball joint structure within the first bushing and the ring within the second bushing, this control arm assembly, when applied to an automotive suspension system, can achieve multi-angle damping effects. Furthermore, these angles are not on the same plane, significantly improving the multi-angle damping effect of the automotive suspension system.

[0004] However, this device has its shortcomings. Through the ball joint structure in the first bushing and the ring sleeve in the second bushing, the control arm assembly can have a multi-angle damping effect when applied to the car suspension system. Moreover, these angles are not on the same plane, which greatly improves the multi-angle damping effect of the car suspension system. However, this device has the problem that the suspension connection is very easy to be damaged when the vehicle is driven for a long time and faces different terrains. Utility Model Content

[0005] The purpose of this invention is to provide a high-load control arm to solve the problem mentioned in the background art. The device, through the ball joint structure in the first bushing and the ring sleeve in the second bushing, enables the control arm assembly to have multi-angle shock absorption effect when applied to the automotive suspension system. Moreover, these angles are not on the same plane, which greatly improves the multi-angle shock absorption effect of the automotive suspension system. However, this device has the problem that the suspension connection body is easily damaged due to the vehicle driving for a long time and facing different terrains.

[0008] Furthermore, the reinforcement structure includes a metal reinforcement interface and an outer connecting ring. The suspension connector includes an outer metal sleeve on one side of which the metal reinforcement interface is fixedly connected. An outer connecting ring is fixedly connected to the outer side of the metal reinforcement interface and an inner connecting ring is fixedly connected to the inner side of the outer connecting ring.
