Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a lower control arm of an automobile suspension. Background Art

[0002] The suspension control arm is an important component in the automobile suspension system. It plays the role of transmitting force and guiding. The lightweight design of the control arm must be based on meeting certain design requirements, including strength, stiffness and natural frequency performance.

[0003] After searching, the application with patent number CN202121624463.7 discloses a lower control arm for the front suspension of an automobile, including a control arm body, a reinforcing rib and a bushing mounting portion. Bushing mounting portions are provided at both ends of the upper side of the control arm body. The bushing mounting portions are fixedly connected to the control arm body. Grooves are provided on both the left and right sides and the upper and lower ends of the bushing mounting portion. Limit blocks are clamped in the grooves on the bushing mounting portion.

[0004] Although the lower control arm of the automobile front suspension can protect the bushing installation part from dust by providing an upper dust cover and a lower dust cover, the lower control arm of the automobile front suspension has a groove on the bushing installation part in order to limit the dust cover, which reduces the strength of the bushing installation part and poses a safety hazard.

[0005] Therefore, we propose a lower control arm for an automobile suspension. Utility Model Content

[0006] In response to the deficiencies of the prior art, the utility model provides a lower control arm for an automobile suspension, which solves the problem that in the prior device, a groove is provided in the bushing mounting portion in order to limit the dust cover, which reduces the strength of the bushing mounting portion and poses a safety hazard.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a lower control arm of an automobile suspension, comprising a control arm body, bushing mounting parts are provided at both ends of the upper side of the control arm body, a ball pin mounting hole is provided at the bottom end of the control arm body, and uniformly distributed reinforcing rods are fixedly installed on the outer surface of the bushing mounting part, threaded holes are provided at both ends of the reinforcing rods, and dustproof components are provided at both ends of the bushing mounting part, and the dustproof components include a first pad and a second pad in the shape of a semicircular ring and the same specifications, the side walls of the first pad and the second pad are provided with mounting holes opposite to the position of the threaded holes, and the first pad and the second pad are fixedly provided with a first dust cover and a second dust cover in the shape of a semicircle and the same specifications on the side away from the bushing mounting part.

[0008] Preferably, the interior of the mounting hole is movably sleeved with a bolt, and the bolt is threadedly sleeved inside the threaded hole, wherein the first pad and the second pad can be fixed to the two ends of the bushing mounting portion by the bolt passing through the mounting hole and threadedly sleeved inside the mounting hole.

[0009] Preferably, the outer surfaces of the first pad and the second pad are both adhered with rubber, so as to make the first pad and the second pad fit more tightly with the two ends of the bushing mounting part, so that the rubber fills the gap, thereby preventing dust from entering the interior of the bushing mounting part from the connection between the first pad and the second pad and the bushing mounting part.

[0010] Preferably, an L-shaped slot is provided on the side of the first dust cover and the first pad, and an L-shaped strip is fixedly installed on the side of the second dust cover and the second pad, and the L-shaped strip is slidably fitted inside the L-shaped slot, so as to facilitate the first dust cover and the second dust cover to be connected together, thereby preventing dust from entering the interior of the bushing mounting part from the connection between the first dust cover and the second dust cover.

[0011] The utility model provides a lower control arm for an automobile suspension, which has the following beneficial effects:

[0012] 1. The automobile suspension lower control arm increases the strength of the bushing mounting portion by means of a reinforcing rod. The provision of bolts and threaded holes allows dustproof assemblies to be mounted on both ends of the bushing mounting portion, thereby increasing the strength of the bushing mounting portion and improving the safety of the bushing mounting portion during use. The bushing mounting portion is protected and dustproofed by the first pad, the second pad, the first dust cover, and the second dust cover, further increasing the safety of the bushing mounting portion during use and extending its service life. This solves the problem of existing devices that, in order to limit the dust cover, provide a groove in the bushing mounting portion, which reduces the strength of the bushing mounting portion and poses a safety hazard.

[0013] 2. The automobile suspension lower control arm can make the first pad and the second pad fit more tightly with the two ends of the bushing mounting portion by sticking rubber on the outer surfaces of the first pad and the second pad, so that the rubber fills the gap, thereby preventing dust from entering the interior of the bushing mounting portion from the connection between the first pad and the second pad and the bushing mounting portion. The first dust cover and the second dust cover are clamped together by the arrangement of the L-shaped slot and the L-shaped strip, thereby preventing dust from entering the interior of the bushing mounting portion from the connection between the first dust cover and the second dust cover. At the same time, the strength of the connection between the L-shaped slot and the L-shaped strip can be increased, thereby improving the protection and dustproof effect of the bushing mounting portion.
