Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive suspension components, specifically to a suspension control arm for reducing stress. Background Technology
[0002] The suspension system is a crucial assembly in modern automobiles, significantly impacting ride comfort and handling stability. The control arm (also known as the swing arm), as a guiding and force-transmitting element of the suspension system, transmits various forces acting on the wheels to the vehicle body, ensuring the wheels move along a specific trajectory. When a vehicle traverses uneven surfaces, the suspension system operates to maintain ride comfort. However, when driving over uneven sections, the forces transmitted from the ground to the control arm are entirely absorbed by the rigid structure of the control arm, leading to fatigue and reduced lifespan. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology.
[0004] A stress-relieving suspension control arm is provided to reduce stress and extend the service life of the control arm.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stress-reducing suspension control arm, comprising an arm body, wherein the arm body is provided with a ball pin, a large bushing, and a small bushing at three ends, characterized in that: the arm body is provided with multiple through holes, each through hole is provided with a stress-absorbing component, the stress-absorbing component includes a rotating seat capable of omnidirectional rotation, the rotating seat is provided with springs arranged opposite each other, steel balls are provided between the springs, the steel balls are fixedly connected to the springs at both ends, and the end of each spring opposite the steel ball is connected to the rotating seat.
[0006] A further feature of this invention is that the rotating seat includes an outer ring and an inner ring disposed within the outer ring. The upper and lower ends of the inner ring are respectively hinged to the inner ring of the outer ring, and the inner ring can rotate laterally. The two ends of the outer ring are respectively hinged to the inner wall of the through hole, and the outer ring can rotate longitudinally. The end of the spring relative to the steel ball is respectively fixedly connected to the inner wall of the inner ring.
[0007] A further feature of this invention is that: each end of the steel ball is provided with a first hanging ring, and the inner ring of the inner circle is provided with a second hanging ring opposite each other, with each end of the spring respectively attached to the first hanging ring and the second hanging ring.
[0008] A further feature of this invention is that multiple through holes are provided along the arm body, and each through hole is provided with the aforementioned stress-absorbing component.
[0009] The present invention with the above features: when the control arm is subjected to force, the steel ball is displaced and compresses the spring in the corresponding direction, thereby reducing stress. The outer ring and the inner ring are hinged in the longitudinal direction, and the outer ring is hinged in the transverse direction of the through hole, so that the inner ring can rotate outward. The control arm rotates at an angle, so that the steel ball and the spring cooperate to reduce the stress in the corresponding direction.
[0010] The beneficial effects of this invention are: reduced stress and extended service life of the control arm.
[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
