Description

Technical Field

[0001] This utility model relates to the field of automotive chassis technology, specifically to a lower control arm front bushing assembly. Background Technology

[0002] The lower control arm is a key component of the automotive suspension system. It is usually connected to the wheel steering knuckle at one end via a ball joint or bushing, and to the body or frame at the other end. Its main function is to support the wheel and transmit longitudinal and lateral forces. Together with components such as springs and shock absorbers, it maintains wheel alignment parameters to ensure the stability, handling, and ride comfort of the vehicle. Its structural strength and connection reliability are crucial to driving safety.

[0003] When the existing lower control arm front bushing is installed by compression, it is installed from one side to the inner wall of the lower control arm. This results in greater compression friction on the installation side, which may lead to an increase in the diameter of the hole on the installation side. This, in turn, increases the gap between the installation side and the bushing. At the same time, the rubber body has low strength, making it very easy to break during use. This can lead to damage to the vehicle suspension, as well as issues such as vehicle pulling to one side and abnormal noises from the chassis when the vehicle is in motion. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lower control arm front bushing assembly, which has the advantages of uniform distribution of installation friction and reinforced rubber body, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a lower control arm front bushing assembly, including an inner bushing ring, a rubber body fixedly installed on the outer wall of the inner bushing ring, an inner fixing ring fixedly installed on the outer wall of the rubber body, an outer fixing ring fixedly installed on the outer wall of the inner fixing ring, a secondary pressing ring slidably sleeved on the outer wall of the inner fixing ring, a reinforcing component provided on the inner wall of the rubber body, an extension ring one fixedly installed on the outer wall of the inner fixing ring, a second inclined surface on the outer wall of the extension ring one, an extension ring two fixedly installed on the outer wall of the secondary pressing ring, and a first inclined surface on the outer wall of the extension ring two.

[0006] As a preferred technical solution of this utility model: the reinforcing component includes an inner steel wire ring, an outer steel wire ring is provided outside the inner steel wire ring, a connecting steel wire is fixedly installed on the outer wall of the inner steel wire ring, a second connecting beam is fixedly installed on the outer wall of the inner steel wire ring, and a first connecting beam is fixedly installed on the outer wall of the outer steel wire ring.

[0007] As a preferred technical solution of this utility model: the number of outer steel wire rings and connecting beams is several, and the several outer steel wire rings are arranged in a straight line on the inner wall of the rubber body, and the several connecting beams are arranged in a circular array on the outer wall of the several outer steel wire rings.

[0008] As a preferred technical solution of this utility model: the number of inner steel wire rings and connecting beams is several, and the several inner steel wire rings are arranged in a straight line on the inner wall of the rubber body, and the several connecting beams are arranged in a circular array on the outer wall of the inner steel wire rings.

[0009] As a preferred technical solution of this utility model: the positions of the first inclined plane and the second inclined plane are corresponding, and the first inclined plane and the second inclined plane are parallel.

[0010] As a preferred technical solution of this utility model: the thickness of the secondary pressing ring is twice that of the second extension ring, and the thickness of the second extension ring and the first extension ring are the same, and the thickness of the inner fixing ring is twice that of the first extension ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The lower control arm front bushing assembly is manufactured by pressing the inner bushing ring, rubber body, inner fixing ring, and outer fixing ring into the mounting hole of the lower control arm. The lower control arm is then flipped, causing the mounting hole to flip as well. A secondary pressing ring is then pressed into the mounting hole of the lower control arm, causing the secondary pressing ring to move the second extension ring towards the first extension ring, so that the second inclined surface and the first inclined surface are in contact. Through the contact of the first and second inclined surfaces, the first inclined surface moves upward towards the second inclined surface, causing the second extension ring to cover the first extension ring. The tightening force of the second extension ring fixes the second extension ring to the outer wall of the first extension ring. This allows the lower control arm to be pressed in from both sides during installation, preventing severe wear on one side of the mounting hole due to pressure from one side.

[0012] 2. The lower control arm front bushing assembly supports one side of the rubber body through the inner steel wire ring and the second connecting beam, while supporting the other side of the rubber body through the second connecting beam and the inner steel wire ring. This increases the overall strength of the inner and outer sides of the rubber body. At the same time, several connecting steel wires connect the inner and outer steel wire rings, forming a connection between them. This improves the overall shear resistance of the rubber body and thus extends its service life. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1 - Figure 5 A lower control arm front bushing assembly includes an inner bushing ring 1, a rubber body 2 fixedly mounted on the outer wall of the inner bushing ring 1, an inner fixing ring 3 fixedly mounted on the outer wall of the rubber body 2, an outer fixing ring 4 fixedly mounted on the outer wall of the inner fixing ring 3, a secondary pressing ring 5 slidably sleeved on the outer wall of the inner fixing ring 3, a reinforcing component 6 provided on the inner wall of the rubber body 2, an extension ring 7 fixedly mounted on the outer wall of the inner fixing ring 3, a second inclined surface 10 provided on the outer wall of the extension ring 7, an extension ring 8 fixedly mounted on the outer wall of the secondary pressing ring 5, and a second inclined surface 9 provided on the outer wall of the extension ring 8.

[0017] In the above structure, the extension ring 7 expands the extension ring 8, so that the extension ring 8 covers the outer wall of the extension ring 7. At this time, the extension ring 8 is tightened towards the extension ring 7 by the inward contraction force, so that the extension ring 7 and the extension ring 8 generate friction, so that the extension ring 7 and the extension ring 8 form a fixed relationship, and thus the secondary pressing ring 5 and the inner fixing ring 3 form a fixed relationship.

[0018] In a preferred embodiment: the reinforcing component 6 includes an inner steel wire ring 601, an outer steel wire ring 602 is provided outside the inner steel wire ring 601, a connecting steel wire 603 is fixedly installed on the outer wall of the inner steel wire ring 601, a second connecting beam 605 is fixedly installed on the outer wall of the inner steel wire ring 601, and a first connecting beam 604 is fixedly installed on the outer wall of the outer steel wire ring 602.

[0019] In the above structure, the outer steel wire ring 602 and the inner steel wire ring 601 are connected by the connecting steel wire 603, so that the outer steel wire ring 602 and the inner steel wire ring 601 are connected, thereby creating a connection between the outer steel wire ring 602 and the inner steel wire ring 601 inside the rubber body 2, which improves the overall shear resistance of the rubber body 2.

[0020] In a preferred embodiment, there are several outer steel wire rings 602 and several connecting beams 604, and the several outer steel wire rings 602 are arranged in a straight line on the inner wall of the rubber body 2, and the several connecting beams 604 are arranged in a circular array on the outer wall of the several outer steel wire rings 602.

[0021] In the above structure, several outer steel wire rings 602 are connected by several connecting beams 604, thereby forming a support between the several outer steel wire rings 602. This, in turn, forms a protective layer between the several outer steel wire rings 602 and the several connecting beams 604. At the same time, since the several outer steel wire rings 602 and the several connecting beams 604 are located inside the rubber body 2, they support the inner and outer sides of the rubber body 2, thereby enhancing the overall external strength of the rubber body 2.

[0022] In a preferred embodiment, there are several inner steel wire rings 601 and several connecting beams 605, with several inner steel wire rings 601 arranged in a straight line on the inner wall of the rubber body 2, and several connecting beams 605 arranged in a circular array on the outer wall of the inner steel wire rings 601.

[0023] In the above structure, several inner steel wire rings 601 are connected by several connecting beams 605, thereby supporting the inner steel wire rings 601. In turn, the inner steel wire rings 601 and the connecting beams 605 support the inner side of the rubber body 2, thereby enhancing the inner strength of the rubber body 2.

[0024] In a preferred embodiment: the positions of inclined plane 9 and inclined plane 10 are corresponding, and inclined plane 9 and inclined plane 10 are parallel.

[0025] In the above structure, by pushing the secondary pressing ring 5 towards the inner fixing ring 3, the secondary pressing ring 5 causes the extension ring 2 8 to move towards the extension ring 1 7, thereby causing the inclined surface 1 9 and the inclined surface 2 10 to fit together. At this time, the secondary pressing ring 5 is pressed further, causing the secondary pressing ring 5 to cause the extension ring 2 8 to continue moving towards the extension ring 1 7, thereby causing the inclined surface 1 9 to move upward through its fit with the inclined surface 2 10, thereby causing the extension ring 2 8 to move to the outer wall of the extension ring 1 7, at which point the extension ring 2 8 covers the extension ring 1 7.

[0026] In a preferred embodiment: the thickness of the secondary pressing ring 5 is twice that of the extension ring 2 8, and the extension ring 2 8 and the extension ring 1 7 have the same thickness, and the thickness of the inner fixing ring 3 is twice that of the extension ring 1 7.

[0027] In the above structure, when the extension ring 2 8 covers the extension ring 1 7, since the extension ring 2 8 and the extension ring 1 7 have the same thickness, the thickness of the extension ring 2 8 and the extension ring 1 7 after being stacked is the same as the thickness of the secondary pressing ring 5. At the same time, since the thickness of the inner fixing ring 3 is twice that of the extension ring 1 7, the thickness of the extension ring 2 8 and the extension ring 1 7 after being stacked is the same as the thickness of the inner fixing ring 3. Therefore, after the extension ring 2 8 covers the extension ring 1 7, its thickness will not exceed that of the inner fixing ring 3 and the secondary pressing ring 5, so that it cannot damage the inner diameter of the mounting hole of the lower control arm.

[0028] Working principle: When pressing the equipment, the inner liner ring 1, rubber body 2, inner fixing ring 3, and outer fixing ring 4 are placed inside the mounting hole of the lower swing arm. The pressing equipment then presses the outer fixing ring 4, causing it to enter the inner wall of the mounting hole. The outer fixing ring 4 is then fixed to the inner wall of the mounting hole by its close fit with the mounting hole. The lower swing arm is then flipped, and the secondary pressing ring 5 is pressed into the mounting hole from the other side. This causes the secondary pressing ring 5 to move the extension ring 2 8 towards the extension ring 1 7, thus bringing the inclined surface 1 9 and inclined surface 2 10 into contact. The secondary pressing ring 5 is then pressed further, causing the extension ring 1 9 to move towards the extension ring 1 7. 28 continues to move towards extension ring 7, causing inclined surface 9 to move upward through contact with inclined surface 10, thereby moving extension ring 28 to the outer wall of extension ring 7. At this time, extension ring 28 covers extension ring 7, thereby fixing secondary pressing ring 5 to the inner wall of the mounting hole. After the equipment is installed, the interior of rubber body 2 is reinforced for the first time by inner steel wire ring 601 and connecting beam 2 605, and the interior of rubber body 2 is reinforced for the second time by outer steel wire ring 602 and connecting beam 1 604. At the same time, the inner steel wire ring 601 and outer steel wire ring 602 are connected by connecting steel wire 603, thereby improving the overall shear resistance of reinforcing component 6, and thus improving the shear resistance of rubber body 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
