[0003] The triangular arm assembly is connected to the wheel component through the suspension ball head, and is connected to the frame through its own components. Rubber bushings are installed at the connection between the triangular arm and the frame for shock absorption. However, after long-term use, the internal rubber of the rubber bushing will deteriorate, causing the triangular arm to collide with the frame during swinging, causing abnormal noise and affecting comfort and handling.

[0004] For example, an automobile triangular arm with a shock-absorbing function having an application number of 201520319445.6 includes a suspension ball head, a triangular arm body, a body, a head, a first tail, a second tail, a rubber bushing 1, a rubber bushing 2, a shock-absorbing rubber pad and a steering knuckle, and shock-absorbing rubber pads are arranged on both sides of the rubber bushing 2.

[0005] The above patent achieves the effect of eliminating abnormal noise and improving shock absorption by arranging a shock-absorbing rubber pad on the rubber bushing 2. However, when the triangular arm is connected to the frame, it needs to be assisted in locking by nuts and washers. When the shock-absorbing rubber pad is vibrated, it will rotate, which will hinder the locking of the nuts and washers. Utility Model Content

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figures 1 to 5 As shown, the utility model can be implemented through the following embodiments: a noise reduction type automobile triangle arm assembly, including a main body 1, a reinforcement plate 11 is welded on the main body 1, the main body 1 is divided into an arm body 12, an arm body 2 13 and an arm body 3 14, a connecting rod 131 is welded on the arm body 2 13, a fixing frame 2 is installed on the connecting rod 131, a connecting portion 21 is provided on the fixing frame 2, a bushing 141 is welded on the arm body 3 14, a rubber sleeve 3 and a special part 4 are installed in the bushing 141, and the rubber sleeve 3 is composed of an inner bushing 31, a colloid 32 and an outer bushing 33.

[0024] A fixing frame 2 is installed on the connecting rod 131. The fixing frame 2 serves as a connecting piece to connect the frame and the main body 1. The connecting part 21 arranged on the fixing frame 2 is higher than the triangular arm, so that the triangular arm is located below the frame, increasing the activity space of the triangular arm and preventing the triangular arm from colliding with the frame and making abnormal noise when the rubber performance deteriorates; the rubber sleeve 13 and the special part 4 installed on the arm body 14 form a buffer structure, and the special part 4 serves as a secondary buffer to reduce the impact on the rubber sleeve 3; the bushing 141 serves as an external support member to ensure that the outer periphery of the rubber sleeve 3 and the special part 4 is connected to the main body 1 as a whole.

[0025] like Figures 1 to 4 As shown, the fixing frame 2 is provided with a mounting sleeve 22, and a rubber sleeve 25 is installed in the mounting sleeve 22, and the rubber sleeve 25 is sleeved on the connecting rod 131. The rubber sleeve 25 is sleeved on the connecting rod 131, providing a fulcrum for the triangular arm to be installed on the fixing frame 2, without being directly installed on the frame, and the rubber sleeve 25 provides a buffer support.

[0026] like Figure 3 As shown, the rubber sleeve 5 is divided into an inner sleeve 51 , a colloid 52 and an outer sleeve 53 . The inner sleeve 51 is inserted into the colloid 52 , and an annular groove 521 is formed on the colloid 52 .

[0027] The colloid 2 52 is sandwiched between the inner sleeve 2 51 and the outer sleeve 2 53, so that the colloid 2 52 will not deform arbitrarily while providing support and cushioning, and will not be damaged, resulting in a shortened service life; the inner sleeve 2 51 is inserted into the colloid 2 52, so that there is a buffer between the connecting rod 131 and the inner sleeve, reducing the impact on the colloid 2 52 and extending the service life of the rubber sleeve 2 5; the opening of the annular groove 521 allows the colloid 2 52 to deform to a certain extent, preventing the colloid 2 52 from being damaged when deformation occurs.

[0028] like Figure 1 and Figure 5 As shown, the inner sleeve 31 and the colloid 32 extend from the rubber sleeve 3 to form a mounting portion 34. The mounting portion 34 is used to cooperate with the special part 4 to relieve the impact force. At the same time, the mounting portion 34 is arranged so that when the main body 1 is impacted and swung, the colloid 32 is deformed to make the inner sleeve 31 swing, allowing the main body 1 to move.

[0029] like Figure 5 As shown, the colloid 1 32 is provided with a groove 1 321 and a groove 2 322. The provision of the groove 1 321 and the groove 2 322 facilitates the deformation of the colloid 1 32, and prevents the rubber of the colloid 1 32 from folding, squeezing or pulling each other when the colloid 1 32 is deformed, and the mechanical properties of the squeezing and pulling parts change, causing the colloid 1 32 to tear, thereby shortening the service life.

[0030] like Figure 5 As shown, a rubber ring 41 is arranged inside the special part 4, and the special part 4 is sleeved outside the mounting portion 34 and is concentric with the rubber sleeve 3. The special part 4 is mounted outside the mounting portion 34 of the rubber sleeve 3, so that when the rubber sleeve 3 is deformed, if the main body 1 swings too violently, the mounting portion 34 of the rubber sleeve 3 will contact the rubber ring 41 of the special part 4, and the impact on the rubber sleeve 3 will be released to the rubber ring 41 and absorbed, preventing the rubber sleeve 3 from deforming too much and causing the colloid 32 to be subjected to too much force, thereby improving the service life of the rubber sleeve 3.

[0031] like Figure 3 and Figure 4 As shown, the colloid 52 is provided with a connecting portion 522, the shape of which matches the connecting rod 131, and the diameter of the connecting portion 522 is smaller than the inner sleeve 51. The connecting portion 522 fits the connecting rod 131, so that when the connecting rod 131 swings with the main body 1, the force is dispersed to the connecting portion 522, reducing the force on the colloid 52; at the same time, the diameter of the connecting portion 522 is smaller than the inner sleeve 51, and there is a certain space between the connecting portion 522 and the colloid 52. When the connecting rod 131 swings, the connecting portion 522 is stressed and transmits the force to the inner sleeve 51, and the inner sleeve 51 drives the colloid 52 to deform, so that the connecting rod 131 does not rub against the colloid 52 outside the connecting portion 522, preventing the friction between the colloid 52 and the connecting rod 131 from causing wear and tear, thereby reducing the service life.

[0032] The working principle of the utility model is as follows: when a car travels over a bumpy road, the wheels move up and down, and the suspension ball head of the wheel component transmits force to the arm body 1 12 of the triangular arm, and the triangular arm swings accordingly, and the swinging triangular arm transmits force to the arm body 2 13 and the arm body 3 14.

[0033] The connecting rod 131 on the arm body 13 swings accordingly, so that the rubber sleeve 5 in contact with the connecting rod 131 is subjected to force. The connecting rod 131 first contacts the connecting portion 522 of the rubber sleeve 5. The connecting portion 522 is a part of the colloid 52. After the connecting portion 522 is subjected to force buffering, the inner bushing arranged behind the connecting portion 522 limits the further deformation of the connecting portion 522 and transmits the force to the colloid 52. The colloid 52 is deformed under force and transmits the force after secondary buffering to the fixing frame 2 through the outer bushing 53.

[0034] The arm body 3 14 is connected to the vehicle frame. After being stressed, the bushing transmits the force to the rubber sleeve 3. The colloid 32 in the rubber sleeve 3 is deformed under the stress, so that the mounting portion 34 and the inner bushing 31 swing. The colloid 32 outside the mounting portion 34 contacts the rubber ring 41 inside the special part 4 and absorbs the impact force, reducing the impact force on the colloid 32 and reducing the range of movement of the colloid 32, preventing the colloid 32 from deteriorating under long-term swinging and shortening the service life.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0036] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
