Description

Technical Field

[0001] The utility model belongs to the field of control arms, in particular to a high-strength automobile control arm. Background Art

[0002] The control arm is an important safety and guide component in the automobile chassis system. It bears various loads during the driving of the automobile. Its strength and stiffness have a decisive influence on the performance of the entire vehicle. As a guide and force transmission element of the automobile suspension system, the control arm transmits various forces acting on the wheel to the body, while ensuring that the wheel moves along a certain trajectory. The automobile control arm elastically connects the wheel and the body through a ball joint or a bushing.

[0003] The ball joint on the control arm generally bears greater pressure and impact force. When the force on the ball joint is uneven, it will cause torsional damage to the joint. Moreover, long-term impact will greatly accelerate the damage to the control arm, thereby greatly shortening the service life of the control arm. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a high-strength automobile control arm.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength automobile control arm, comprising a control arm, wherein a main interface and a ball head interface are fixed on the outer peripheral side of the control arm, wherein the main interfaces are at least two, and the ball head interface is at least one, and the characteristic is that a reinforcement component is provided in the ball head interface;

[0006] The reinforcement component includes a detachable inner bushing and two sliding rods sliding in the control arm. A limiting block is fixed at one end of the sliding rod. The inner bushing is limited by the limiting block, and the ball head interface is strengthened by the sliding rod to prevent it from torsional damage.

[0007] Optionally, notches are provided in the ball head interface and the inner sleeve, and the two notches are combined to form a cavity, and the limit block is stuck in the cavity.

[0008] Optionally, both side end surfaces of the control arm are provided with sliding grooves, the sliding rod slides in the sliding grooves, and the cross-section of the sliding grooves is T-shaped.

[0009] Optionally, a spring is fixed between the slide rod and the end surface of the slide groove, and a push block is fixed to the end surface of the slide rod away from the control arm.

[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Due to the setting of the reinforcement component, the setting of the slide rod can avoid torsional damage to the ball head interface on the control arm and increase the strength of the control arm.

[0012] 2. The inner bushing can also be set, and the inner bushing can be directly replaced after it is worn and can continue to be used, which greatly extends the service life of the control arm. At the same time, the inner bushing can also be used to reduce the shock of the control arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0018] As shown in Figure 1-3, a high-strength automobile control arm includes a control arm 10, and a main interface 11 and a ball head interface 12 are fixed on the outer peripheral side of the control arm 10, wherein the main interfaces 11 are at least two, and the ball head interface 12 is at least one, and a reinforcing component is provided in the ball head interface 12, and the reinforcing component includes a detachable inner bushing 13, and two slide bars 14 sliding in the control arm 10, and a limiting block 17 is fixed at one end of the slide bar 14, and the inner bushing 13 is limited by the limiting block 17, and the ball head interface 12 is strengthened by the slide bar 14 to avoid torsional damage, and notches are provided in the ball head interface 12 and the inner bushing 13, and the two notches are combined to form a cavity, and the limiting block 17 is stuck in this cavity.

[0019] Slide grooves 15 are provided on both side end faces of the control arm 10 , and the slide rod 14 slides in the slide groove 15 . The cross section of the slide groove 15 is T-shaped. A spring 16 is fixed between the slide rod 14 and the end face of the slide groove 15 . A push block 18 is fixed to the end face of the slide rod 14 away from the control arm 10 .

[0020] When in use, the ball head rod is inserted into the inner sleeve 13. Through the setting of the inner sleeve 13, the control arm can be shock-absorbing, and the sliding rod 14 and the limit block 17 are stuck in the ball head interface 12, so as to avoid torsional damage to the ball head interface 12 on the control arm. At the same time, through the setting of the inner sleeve 13, the inner sleeve 13 can be directly replaced after it is worn and can continue to be used, which greatly extends the service life of the control arm. When the inner sleeve 13 needs to be removed, it is only necessary to push the push block 18 to the side away from the ball head interface 12, so that the sliding rod 14 squeezes the spring 16 to drive the limit block 17 to disengage from the inner sleeve 13, and then the inner sleeve 13 can be directly removed for replacement, making the replacement process more convenient.

[0021] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
