Description

Technical Field

[0001] The utility model relates to the technical field of automotive swing arms, and specifically relates to a wear-resistant steering swing arm. Background Art

[0002] The automotive swing arm assembly is a core component of the chassis suspension system. Its main part is usually made of metal, and the quality is relatively stable. However, there are significant differences in the quality of the associated ball head sub-assembly, front rubber bushing, rear rubber bushing, and intermediate bushing. The design of these accessories directly determines the performance of the swing arm assembly. For example, the structural design of the rubber bushing is related to its anti-fatigue property, wear resistance, and shock absorption effect, while the design of the ball head affects the smoothness and durability of its rotation.

[0003] When the ball head of the steering swing arm is damaged, the clearance inside the ball joint will increase significantly. In addition, the wear of the ball head may also cause damage to the dust cover, and the damage of the dust cover will cause the lubricating grease inside the ball head to overflow. Over time, the loss of lubricating grease will not only lead to insufficient lubrication of the ball head, but also further exacerbate the wear and generate more clearance;

[0004] At the same time, the rubber bushing in the steering swing arm will also be damaged due to wear. Common problems include rubber fracture. This kind of damage can usually be clearly observed with the naked eye, especially at the interface between the rubber and both sides, where cracking or even complete disconnection may occur. These wear and damages directly affect the stability of the vehicle during high-speed driving, reduce the handling performance, and the vehicle may not be able to maintain a straight line, thus affecting driving safety.

[0005] Therefore, a wear-resistant steering swing arm is needed to improve the above problems. Content of the Utility Model

[0006] In order to solve the problem that when the steering swing arm is in use, the rubber bushing will also be damaged due to wear, especially at the interface between the rubber and both sides, where cracking or even complete disconnection may occur. These wear and damages directly affect the stability of the vehicle during high-speed driving, the utility model provides a wear-resistant steering swing arm to solve the above problems.

[0011] As a preferred solution of the present utility model, the vibration sensor is mounted on the outer wall of the fixing plate. The mounting housing is sleeved on the outer wall of the ball joint. A lubricating oil sensor is mounted on the outer wall of the mounting housing.

[0012] As a preferred solution of the present utility model, a bushing fixing seat is mounted on the outer wall of the steering swing arm, and a bushing fixing member is mounted on the inner wall of the bushing fixing seat. The fixed housing plays a limiting role on the bushing connecting member.

[0013] As a preferred solution of the present utility model, the controller is electrically connected to the audible and visual alarm, the vibration sensor, and the lubricating oil sensor through wires respectively. Two groups of threaded grooves are provided and are respectively located at the opposite ports of the bushing mounting seat.

[0014] As a preferred solution of the present utility model, two groups of fixed housings are provided and are respectively located at the opposite ports of the bushing mounting seat. Multiple groups of limiting housings are provided and the limiting housings are arranged in a circular array on the inner wall of the installation groove.

[0015] As a preferred solution of the present utility model, lubricating oil is provided in the inner cavity of the sponge block.

The fixed housing is threadedly connected to the outer wall of the thread groove for fixation, and the fixed housing plays a role in fixing the bushing connecting piece. When the bushing connecting piece vibrates and displaces, the bushing connecting piece exerts extrusion on the extrusion plate, causing the extrusion plate to slide inward in the communication groove. The extrusion plate extrudes the sponge block. Under the action of the lubricating oil arranged in the inner cavity of the sponge block, the lubricating oil in the sponge block is extruded, thereby lubricating the ball and the bushing connecting piece, and further reducing wear, so as to solve the problem that the rubber bushing in the steering swing arm will also be damaged due to wear. These wear and damages directly affect the stability of the vehicle during high-speed driving, reduce the handling performance, and the vehicle may not be able to maintain a straight line, thus affecting driving safety.

[0027] In this embodiment, specifically refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the wear-resistant bushing assembly 6 includes a bushing mounting seat 601. The bushing mounting seat 601 is mounted on the outer wall of the steering swing arm 1. At the port of the bushing mounting seat 601, there are threaded grooves 602. Two groups of threaded grooves 602 are provided and are respectively located at the opposite ports of the bushing mounting seat 601. And a fixed housing 603 is threadedly connected to the outer wall of the threaded groove 602. Two groups of fixed housings 603 are provided and are respectively located at the opposite ports of the bushing mounting seat 601. A bushing connecting member 604 is mounted on the inner wall of the bushing mounting seat 601. On one side of the bushing connecting member 604 and on the inner wall of the bushing mounting seat 601, there is an installation groove 605. A limiting housing 606 is mounted on the inner wall of the installation groove 605. Multiple groups of limiting housings 606 are provided and the limiting housings 606 are arranged in a circular array on the inner wall of the installation groove 605. A sponge block 607 is provided on the inner wall of the limiting housing 606. The inner cavity of the sponge block 607 is provided with lubricating oil. On one side of the sponge block 607 and on the opposite outer walls of the limiting housing 606, there are communication grooves 608. Two groups of communication grooves 608 are provided and are respectively located on the opposite outer walls of the limiting housing 606. And the communication groove 608 is located on one side of the ball 610. On the other side of the sponge block 607 and on the outer wall of the limiting housing 606, there is an extrusion plate 609 embedded and installed. The connection mode between the extrusion plate 609 and the limiting housing 606 is a sliding connection. One end of the extrusion plate 609 is attached to the outer wall of the bushing connecting member 604. On one side of the bushing connecting member 604 and on the inner wall of the installation groove 605, there are balls 610. Multiple groups of balls 610 are provided and are respectively located on the inner wall of the installation groove 605. And the connection mode between the ball 610 and the bushing connecting member 604 is a sliding connection.

[0028] In this embodiment, specifically referring to Figure 1 and Figure 2 , the monitoring assembly 5 includes a controller 501, an audible and visual alarm 502, a vibration sensor 503 and a mounting housing 504. The controller 501 is mounted on the outer wall of the steering swing arm 1. The audible and visual alarm 502 is mounted on the outer wall of the steering swing arm 1. The vibration sensor 503 is mounted on the outer wall of the fixing plate 3. The mounting housing 504 is sleeved on the outer wall of the ball joint 4. A lubricating oil sensor 505 is mounted on the outer wall of the mounting housing 504;

[0029] Among them, a bushing fixing seat 7 is mounted on the outer wall of the steering swing arm 1. And a bushing fixing member 8 is mounted on the inner wall of the bushing fixing seat 7. The fixed housing 603 plays a role in limiting the bushing connecting member 604. When the controller 501 is electrically connected to the audible and visual alarm 502, the vibration sensor 503 and the lubricating oil sensor 505 through wires respectively, the device is powered on.

[0030] When the wear-resistant steering swing arm of this solution is working, it is sleeved on the outer wall of the ball head connector 4 through the mounting housing 504. Under the action of the lubricating oil sensor 505 installed on the outer wall of the mounting housing 504, when the ball head connector 4 is damaged by long-term wear, the lubricating oil of the ball head connector 4 flows out, thereby enabling the lubricating oil sensor 505 to generate data. At the same time, the electrical signal generated by the lubricating oil sensor 505 is conducted to the controller 501 through a wire. When the ball head connector 4 is worn, the steering swing arm 1 will generate abnormal vibrations. With the controller 501 installed on the outer wall of the steering swing arm 1 and the sound and light alarm 502 installed on the outer wall of the steering swing arm 1, and the vibration sensor 503 installed on the outer wall of the fixed plate 3, the vibration sensor 503 generates data. At the same time, the electrical signal generated by the vibration sensor 503 is conducted to the controller 501 through a wire. When the set value is reached, the controller 501 controls the sound and light alarm 502 to operate, thereby reminding the driver to perform maintenance in a timely manner, thus solving the problem that the wear of the ball head may also cause damage to the dust cover, and the damage of the dust cover will cause the grease inside the ball head to overflow. Over time, the loss of grease will not only lead to insufficient lubrication of the ball head, but also further exacerbate the wear problem.

[0031] A threaded groove 602 is provided at the port of the bushing mounting seat 601, and a fixed housing 603 is threadedly connected to the outer wall of the threaded groove 602. Under the action of the bushing connector 604 mounted on the inner wall of the bushing mounting seat 601, when the bushing connector 604 needs to be maintained and replaced, only after the bushing connector 604 is installed, the fixed housing 603 is sleeved on the port of the bushing mounting seat 601 for installation, so that the fixed housing 603 is threadedly connected to the outer wall of the threaded groove 602 for fixation, and the fixed housing 603 plays a role in fixing the bushing connector 604. At the same time, under the action of the balls 610 mounted on the inner wall of the mounting groove 605 on one side of the bushing connector 604, when the bushing connector 604 is connected and used, the connection contact surface between the bushing connector 604 and the balls 610 is relatively small, greatly reducing wear. At the same time, a sponge block 607 is provided on the inner wall of the limiting housing 606. A communication groove 608 is formed on the outer wall of the limiting housing 606 opposite to one side of the sponge block 607. An extrusion plate 609 is embedded and mounted on the outer wall of the limiting housing 606 on the other side of the sponge block 607. Under the action that one end of the extrusion plate 609 is attached to the outer wall of the bushing connector 604, when the bushing connector 604 vibrates and displaces, the bushing connector 604 exerts extrusion on the extrusion plate 609, causing the extrusion plate 609 to slide inward in the communication groove 608. The extrusion plate 609 extrudes the sponge block 607. Under the action of the lubricating oil provided in the inner cavity of the sponge block 607, the lubricating oil in the sponge block 607 is extruded, thereby lubricating the balls 610 and the bushing connector 604 and further reducing wear, thus solving the problem that the rubber bushings in the steering swing arm will also be damaged due to wear. These wear and damages directly affect the stability of the vehicle during high-speed driving, resulting in a reduction in handling performance. The vehicle may not be able to maintain a straight line, thus affecting driving safety.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
