DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 4As shown, the utility model can be implemented through the following embodiments: a durable automobile control arm assembly includes a fixing frame 1, a connecting hole 11 is provided at one end of the fixing frame 1, a connecting hole 12 is provided at the other end of the fixing frame 1, a rubber sleeve 2 is installed in the connecting hole 11, a rubber sleeve 23 is installed in the connecting hole 12, the rubber sleeve 2 is composed of an outer bushing 21, a colloid 22 and an inner bushing 23, and the rubber sleeve 23 is composed of an outer bushing 31, a colloid 32 and an inner bushing 33.

[0021] The rubber sleeve 1 2 and the rubber sleeve 2 3 are installed in the fixing frame 1, and the impact is buffered by the deformation of the colloid 1 22 and the colloid 2 32. The outer bushing 1 21 and the outer bushing 2 31 are used to contact and connect the fixing frame 1 to ensure that the colloid 1 22 and the colloid 2 32 do not rub against the fixing frame 1. The inner bushing 1 23 and the inner bushing 2 33 connect and support the wheel bracket and the front subframe while protecting the colloid 1 22 and the colloid 2 32.

[0022] like Figure 1 As shown, the connection hole 11 and the rubber sleeve 1 2 are in interference fit, and the connection hole 2 12 and the rubber sleeve 2 3 are in interference fit. The interference fit makes the connection hole 11 and the rubber sleeve 1 2, and the connection hole 2 12 and the rubber sleeve 2 3 tightly connected, preventing the rubber sleeve 1 2 and the rubber sleeve 2 3 from falling off from the fixing frame 1 after being impacted.

[0023] like Figure 1 and Figure 4 As shown, both ends of the inner bushing 33 are provided with holes 331. The holes 331 facilitate the connection of the rubber sleeve 23 with the front subframe, and prevent the friction between the holes 331 and the front subframe when the control arm moves, thereby improving the service life of the rubber sleeve 23.

[0024] like Figure 1 and Figure 2 As shown, the connection hole 11 is provided with a flange 111, and the connection hole 2 is provided with a flange 121. The arrangement of the flange 111 and the flange 121 provides a support point for the rubber sleeve 1 2 and the rubber sleeve 2 3, preventing the rubber sleeve 1 2 and the rubber sleeve 2 3 from swinging relative to the fixing frame due to insufficient contact surface with the fixing frame. The flange 111 and the flange 121 are directly arranged on the fixing frame, and the structural strength is high.

[0025] like Figure 3As shown, the colloid 1 22 is provided with a movable groove 1 221 and a movable groove 222, and a covering portion 1 221a extends from the movable groove 1 221. The opening of the movable groove 1 221 and the movable groove 222 facilitates the colloid 1 22 to have enough space for movement after the fixing frame is impacted and moved, so as to prevent the colloid 1 22 from being permanently deformed at the deformed part after being deformed by force, causing the deformed part to tear, thereby increasing the service life of the colloid 1 22; the covering portion 1 221a is used to fit with the outer bushing 1 21, so that when the colloid 1 22 is deformed, the colloid 1 22 will not peel off from the outer bushing 1 21.

[0026] like Figure 4 As shown, the second colloid 32 is provided with a movable groove 321, and the second colloid 32 is provided with a covering part 222, and the covering part 222 extends to the turning hole 331. The opening of the movable groove 321 facilitates the second colloid 32 to move freely after the fixing frame is impacted and moved, and prevents the second colloid 32 from being permanently deformed at the deformed part after the force deformation of the second colloid 32, causing the deformed part to tear, and reducing the service life of the first colloid 22; after the covering part 222 extends to the turning hole 331, when the second liner 33 moves violently, the second colloid 32 is not easy to fall off from the second liner 33.

[0027] like Figure 1 and Figure 3 As shown, the inner bushing 23 is extended with a support portion 231, and the rubber 22 is provided with an extension portion 223 on the support portion 231. The support portion 231 is used to support the wheel bracket connected to the rubber 22. When the wheel bracket moves, the support portion 231 moves closely with the wheel bracket to prevent the wheel bracket from rubbing against the inner bushing 23 violently, causing the inner bushing 23 to wear, thereby reducing the service life of the rubber sleeve 2.

[0028] like Figure 3 As shown, a step 223a is provided on the extension portion 223. The provision of the step 223a facilitates the connection between the extension portion 223 and the wheel bracket.

[0029] 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.

[0030] 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.
