Description

Technical Field

[0001] This utility model relates to the field of automotive suspension technology, specifically to a forged control arm assembly for automobiles. Background Technology

[0002] The lower control arm assembly is a crucial component of the automotive suspension system. One end connects to the steering knuckle via a ball joint, and the other end connects to the subframe via a rubber bushing. The primary function of the lower control arm assembly is to transmit force and torque, while also providing guidance, controlling the wheel's trajectory during vehicle movement. The elastic element design at its connection point with the subframe reduces vibrations transmitted to the subframe. Existing lower control arm bodies are generally made of iron, resulting in heavy weight, significant unsprung mass, high energy consumption, and poor ride comfort when traversing obstacles. Furthermore, existing lower control arm ball joint assemblies are connected to the lower control arm body via nuts, leading to low assembly efficiency.

[0003] The utility model patent application with publication number "CN215793034U" discloses an aluminum alloy lower control arm for an automotive suspension system, including a front bushing, a rear bushing, and a lower control arm body assembly. The front and rear bushings are press-fitted onto the lower control arm body assembly. The lower control arm body assembly includes a ball joint assembly and a lower control arm body. The ball joint assembly is riveted to the lower control arm body. The lower control arm body is forged from aluminum alloy. The ball joint assembly includes a ball joint, a dust cover, and a retaining ring. The ball joint and cover plate are designed so that the ball joint pin is installed inside the ball joint, which is then installed within the lower control arm body. A cover plate is located below the ball joint, and a dust cover is installed around the center of the ball joint pin. A retaining ring is installed around the bottom of the dust cover. This technical solution achieves the goal of reducing unsprung mass, lowering vehicle energy consumption, and improving vehicle ride comfort when crossing obstacles. Furthermore, since the ball joint pin is riveted to the lower control arm body, there is no need to fix the ball joint pin assembly to the lower control arm body using a nut, which greatly speeds up assembly efficiency.

[0004] The aluminum alloy lower control arm of the automotive suspension system disclosed in the aforementioned document has the following defects: after prolonged use, the ball joint and the ball joint seat will wear down, resulting in the ball joint seat or the ball joint becoming smaller, causing the ball joint seat and the ball joint to not fit together and resulting in uneven rotation.

[0005] Therefore, it can be seen that the existing aluminum alloy lower control arm of the automotive suspension system does not have a good ball joint structure, and it is necessary to improve the existing shortcomings and provide a forged control arm assembly for automobiles. Utility Model Content

[0006] The purpose of this invention is to provide a forged control arm assembly for automobiles to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a forged control arm assembly for automobiles, comprising a control arm body, a lower control arm body fixed to one end of the control arm body, an installation groove formed on the circumferential side of the lower control arm body, and auxiliary components inside the lower control arm body. The number of auxiliary components is fixed to two, each including a ball joint housing, a spring, a movable plate, and a support rod. Several housings are fixedly installed on the inner wall of the lower control arm body, each housing containing a spring. A movable plate is fixedly installed at one end of each spring, and the movable plate is slidably connected to the housing. A support rod is fixedly installed at one end of the movable plate, and a ball joint is fixedly installed at one end of the support rod. After prolonged use, the first ball joint will wear down inside the ball joint housing. When the ball joint wears down, the springs in the two auxiliary components rebound forward, causing the movable plate to move the support rod. The movement of the support rod causes the ball joint housing to continuously engage with the first ball joint, preventing uneven rotation after the first ball joint wears down and increasing the service life of the first ball joint.

[0009] Furthermore, the two ball joints are internally slidably connected by a first ball joint, and a ball joint pin is fixedly installed on the upper surface of the first ball joint. A slot is formed on the peripheral side of the ball joint pin.

[0010] Furthermore, a retaining ring is fixedly installed inside the mounting groove, one end of the retaining ring is connected to the groove, and a dustproof ring is provided inside the retaining ring, which abuts against the ball head pin.

[0011] Furthermore, a first bushing is fixedly installed at one end of the control arm body, and a second ball head is slidably connected to the inner wall of the first bushing, with a connection hole opened on the outer surface of the second ball head.

[0012] Furthermore, a second bushing is fixedly installed at one end of the control arm body.

[0013] Furthermore, a bearing is fixedly installed on the inner wall of the second bushing.

[0014] This utility model has the following beneficial effects:

[0015] (1) When the ball head wears down, the springs in the two auxiliary components rebound forward, causing the movable plate to move the support rod. The movement of the support rod causes the ball head seat to continuously fit against the first ball head, thus avoiding the situation where the ball head does not rotate smoothly after it wears down and increasing the service life of the ball head.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5As shown, this utility model is a forged control arm assembly for automobiles, including a control arm body 1, a lower control arm body 2 fixed to one end of the control arm body 1, a mounting groove 201 formed on the peripheral side of the lower control arm body 2, and an auxiliary component 3 provided inside the lower control arm body 2. The number of auxiliary components 3 is fixed to two, and the auxiliary component 3 includes a ball joint seat 301. The lower control arm body 2 has several housings 302 fixedly installed on its inner wall. Each housing 302 has a spring 303 fixedly installed inside. A movable plate 304 is fixedly installed at one end of each spring 303. The movable plate 304 is slidably connected to the housing 302. A support rod 305 is fixedly installed at one end of the movable plate 304. A ball joint seat 301 is fixedly installed at one end of the support rod 305. After long-term use, the first ball joint 4 will wear down inside the ball joint seat 301. When the ball joint wears down, the springs 303 in the two auxiliary components 3 rebound forward, causing the movable plate 304 to move the support rod 305. The movement of the support rod 305 causes the ball joint seat 301 to continuously fit the first ball joint 4, avoiding the situation where the first ball joint 4 does not rotate smoothly after it wears down, thus increasing the service life of the first ball joint 4.

[0027] Two ball joints 301 are internally slidably connected to a first ball joint 4. A ball joint pin 5 is fixedly installed on the upper surface of the first ball joint 4. A slot 501 is opened on the peripheral side of the ball joint pin 5.

[0028] A retaining ring 6 is fixedly installed inside the mounting slot 201. One end of the retaining ring 6 is connected to the slot 501. A dustproof ring 7 is provided inside the retaining ring 6, and the dustproof ring 7 abuts against the ball head pin 5.

[0029] A first bushing 8 is fixedly installed at one end of the control arm body 1. A second ball head 9 is slidably connected to the inner wall of the first bushing 8. A connection hole 10 is opened on the outer surface of the second ball head 9.

[0030] A second bushing 11 is fixedly installed at one end of the control arm body 1.

[0031] The bearing 12 is fixedly installed on the inner wall of the second bushing 11.

[0032] In use, the ball head 4 is first installed between the two ball head seats 301 by pressing the ball head pin 5 into the interior of the lower control arm body 2. After the first ball head 4 is installed between the two ball head seats 301, the spring 303 is in a compressed state. Then, the retaining ring 6 is installed into the interior of the mounting groove 201 to make the dustproof ring 7 fit against the ball head pin 5 for dust prevention. After long-term use, the first ball head 4 will wear down inside the ball head seat 301. When the ball head wears down, the spring 303 in the two auxiliary components 3 rebounds forward, causing the movable plate 304 to drive the support rod 305 to move. The movement of the support rod 305 causes the ball head seat 301 to continuously fit against the first ball head 4, avoiding the situation where the first ball head 4 does not rotate smoothly after it wears down, thus increasing the service life of the first ball head 4.
