Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to automotive suspension control arms. Background Technology

[0002] The control arm of a car suspension is an important component of the suspension system. It is responsible for connecting the wheels to the car body and controlling the movement of the wheels. Its main function is to ensure that the wheels maintain the correct positioning during driving, while absorbing the impact force from the road surface, improving driving stability and comfort. The control arm is made of steel or aluminum alloy to ensure its sufficient strength and durability.

[0003] There are various design forms of control arms, the most common being upper and lower control arms, front and rear control arms, etc. The upper control arm is usually used to bear the load in the vertical direction, while the lower control arm bears the longitudinal positioning and lateral force of the wheel. The control arm is connected to the wheel axle and the vehicle body through ball joints, allowing the wheel to move up and down within the suspension travel, while restricting the degrees of freedom in other directions. Its design precision directly affects the vehicle's handling performance, driving stability and tire wear.

[0004] The control arm connects the vehicle frame and wheels to ensure its normal operation. When the vehicle is in motion, the up-and-down movement of the wheels, combined with the action of the shock absorption system, causes the control arm to swing up and down, making the vehicle ride smoothly. However, in order to reduce weight, traditional control arms are designed to be hollow. However, the strength of the hollow design is reduced. When encountering very complex road conditions, the control arm may crack or even break due to violent swinging and vibration, affecting driving safety. Therefore, the automotive suspension control arm is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: an automobile suspension control arm, including a control arm body 1. The control arm body 1 is used to mount the wheel on the frame and, in conjunction with the shock absorption system, enables the wheel to float up and down. A reinforcing component is installed inside the control arm body 1, and a lubrication component is installed outside the control arm body 1.

[0034] The reinforcing component includes multiple reinforcing ribs 5, which are externally fixed to the inner wall of the control arm body 1. The reinforcing ribs 5 are used to enhance the strength of the control arm body 1 and prevent breakage. A rear bushing 2 is fixedly connected to the rear side of the control arm body 1, and a ball joint sleeve 3 is fixedly connected to the right side of the control arm body 1. A ball joint pin 4 is provided inside the ball joint sleeve 3. The rear bushing 2 is used to connect to the frame, and the ball joint sleeve 3 is used to limit the movement direction of the ball joint pin 4 and prevent the ball joint pin 4 from falling off. The ball joint pin 4 is used to connect to the wheel. The control arm body 1 has a hollow structure to reduce the weight of the control arm body 1. The reinforcing ribs 5 are in the shape of isosceles triangles with hollows to enhance the bending resistance of the reinforcing ribs 5.

[0035] Reference Figure 1 , Figure 4 , Figure 5The lubrication assembly includes a front bushing 6, which is externally fixedly connected to the left side of the control arm body 1. An oil injection channel 7 is provided inside the front bushing 6. A bolt 8 is threadedly connected to the input end of the oil injection channel 7. A sealing gasket 9 is rotatably connected to the outside of the bolt 8. The front bushing 6 is used to connect to the frame and can rotate on the frame. The oil injection channel 7 is used to deliver lubricating oil to the inside of the front bushing 6. The bolt 8 is used to block the oil injection channel 7 to prevent dust from entering. The sealing gasket 9 is used to seal and prevent lubricating oil from leaking out. The bottom of the sealing gasket 9 abuts against the outside of the front bushing 6 to achieve a seal.

[0036] Working principle: When in use, the control arm body 1 is mounted on the frame by installing the front bushing 6 and the rear bushing 2, and the ball joint pin 4 is mounted on the tire. A shock absorption system is installed above the control arm body 1, enabling the control arm body 1 to be used. As the vehicle moves, the wheels move up and down, causing the control arm body 1 to deflect. During driving on complex road conditions, the control arm body 1 deflects very violently. Through the triangular hollow reinforcing ribs 5, the control arm body 1 is strengthened while reducing its weight. This way, even with violent deflection, the control arm body 1 will not be damaged, and cracks or breaks will not occur, thus avoiding driving safety issues. After a period of use, due to the continuous friction between the bearing connecting the front bushing 6 and the frame, timely lubrication is required. Using an auxiliary tool, the bolt 8 is unscrewed from the oil injection channel 7. Then, lubricating oil is injected into the front bushing 6 through the oil injection channel 7 to effectively lubricate the front bushing 6 and the bearing. Finally, the bolt 8 is screwed back into the oil injection channel 7 using an auxiliary tool and sealed with the sealing gasket 9. The operation is simple and quick.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
