Description

TECHNICAL FIELD

[0001] The utility model relates to an automobile accessory, in particular to a front control arm. BACKGROUND

[0002] The control arm of an automobile is also called a swing arm, and is an important component in the suspension system of the automobile.

The ball seat and the ball pin are fixed in the mounting groove and rely on the force provided by the fixing assembly. However, as the components of the suspension system age, the force direction will deviate to a certain extent, resulting in a large force along the axis of the ball pin. This force is transmitted to the sealing plate through the ball seat, and finally all the force is borne by the fixing assembly. Therefore, when the suspension system ages, the fixing assembly is prone to deformation or even breakage due to excessive force, which poses a certain safety hazard. SUMMARY

[0004] The utility model aims at providing a front control arm, which has stronger structural strength and higher safety factor.

[0005] The above technical purpose of the utility model is achieved by the following technical scheme: a front control arm comprises an arm body, a mounting groove formed on the arm body and having a mounting opening, a ball seat and a ball pin mounted in the mounting groove, a sealing plate for closing the mounting opening, and a fixing assembly for fixing the sealing plate and the arm body, an assembly force bearing component is arranged between the ball seat and the mounting groove, the assembly force bearing component has a fixed state in which the ball seat is fixed in the mounting groove and a non-fixed state, and when the fixing assembly fixes the sealing plate to close the mounting opening, the sealing plate limits the assembly force bearing component to be in the fixed state.

[0006] By adopting the above technical scheme, when the fixing assembly fixes the sealing plate to close the mounting opening, the assembly force bearing component is limited by the sealing plate to be in the fixed state, so that the ball seat can be fixedly mounted in the mounting groove. The assembly force bearing component is arranged to bear the force transmitted to the ball seat by the ball pin, so that after the suspension system ages, the force will not act on the fixing assembly. In this way, the deformation or breakage of the fixing assembly due to excessive force is avoided, the structural strength of the front control arm is prolonged, and the safety factor is improved.

[0007] Further, the assembly force bearing assembly includes an assembly limiting slot formed between the mounting slot wall and the ball seat, the assembly limiting slot includes an assembly path communicating with the mounting opening and a fixing path communicating with the assembly path and used for fixing the ball seat, when the fixing assembly fixes the sealing plate to close the mounting opening, the sealing plate synchronously blocks the assembly path.

[0008] By using the above technical scheme, the assembly force bearing assembly is installed into the fixing path through the assembly path via the mounting opening, so as to form the fixing operation of the ball seat in the mounting slot and realize the switching of the assembly force bearing assembly between the fixed state and the non-fixed state.

[0009] Further, the fixing path is arranged in a circular ring shape around the center of the ball seat, and the assembly path extends along the axis of the ball seat and communicates with the mounting opening and one side of the fixing path.

[0010] By using the above technical scheme, the setting structure increases the bearing stress surface of the assembly force bearing assembly, so that the setting structure has higher structural strength, so as to improve the bearing load of the structure.

[0011] Further, the assembly force bearing assembly further includes a plurality of force bearing blocks capable of entering the fixing path through the assembly path, when the force bearing blocks are located in the fixing path, the movement of the ball seat along the length direction of the ball pin is limited.

[0012] By using the above technical scheme, the force bearing blocks enter the fixing path through the assembly path, and the force bearing blocks located in the fixing path limit the movement of the ball seat along the length direction of the ball pin, so as to fix and bear the stress on the ball seat.

[0013] Further, the sealing plate includes a left plate body and a right plate body, the fixing assembly includes a fixing clamping groove arranged on the mounting slot wall and used for clamping the sealing plate, and a positioning elastic member connecting the left plate body and the right plate body, the positioning elastic member limits the left plate body and the right plate body from separating from the fixing clamping groove.

[0014] By using the above technical scheme, the positioning elastic member positions the left plate body and the right plate body synchronously in the fixing clamping groove, so as to realize the clamping fixing of the sealing plate, and the left plate body and the right plate body can be taken out of the fixing clamping groove by extruding the positioning elastic member.

[0015] Further, the assembly path is provided with a compensation block limiting the force bearing blocks from entering the assembly path.

[0016] By using the above technical scheme, the compensation block can stably limit the force bearing blocks in the fixing path, so as to ensure the stability of the structure.

[0017] Further, the ball pin and the ball seat are connected with a dustproof cover with elasticity, the ball pin is provided with an embedding groove for embedding the dustproof cover, and a plurality of sealing convex rings embedded into the dustproof cover are arranged in the embedding groove.

[0018] By adopting the technical scheme, the orientation of the assembly gap between the dustproof cover and the ball pin is changed through the setting structure of the embedding groove, so that the dustproof cover can achieve good dustproof effect after aging through the setting structure, and the plurality of sealing convex rings are arranged to realize multi-seal, so as to improve the sealing and dustproof effect.

[0019] In summary, the utility model has the following beneficial effects: the structure strength is stronger, and the safety factor is higher. BRIEF DESCRIPTION OF DRAWINGS
