The positioning sleeve is closely attached to the roll ear, and is fixed by a bolt fastener to avoid deformation of the roll ear and improve the safety performance of the vehicle.

[0004] The guide arm frame support connection structure applied to automobile steering in the related art is heavy in weight, and the use of a large number of metal parts increases the kerb weight of the vehicle, resulting in the need to consume more fuel to overcome the weight of the vehicle during driving, which not only increases fuel consumption but also increases operating costs. At the same time, the shock-absorbing effect of the spring structure is particularly unsatisfactory on high-bump road sections. High-bump road sections are usually accompanied by severe road impact and frequent vibration, which can cause great load on the spring.

DETAILED DESCRIPTION

[0021] Therefore, in order to improve the technical problem that the guide arm vehicle frame support connection structure in the related art is heavy, the vehicle consumes more fuel to overcome its own weight during driving, and the operating cost is increased, the embodiments of the present application provide the following solutions.

[0022] Please refer to Figs. 1-3The embodiment of the application provides a kind of automobile air spring guide arm, automobile air spring guide arm includes support arm beam 1, guide arm mounting bracket 2, guide arm structure 3 and shock mounting assembly 4, guide arm mounting bracket 2 is arranged on support arm beam 1, guide arm mounting bracket 2 is provided with guide arm rotating shaft 31, guide arm structure 3 is provided with eyelet 32, guide arm structure 3 is rotatably arranged on guide arm rotating shaft 31 by eyelet 32, shock mounting assembly 4 is arranged on guide arm structure 3.

[0023] In some embodiments, please refer to Figs. 1-3 , shock mounting assembly 4 includes first rotating shaft 41, second rotating shaft 43, second fixed seat 42 and shock absorber 44, first rotating shaft 41 is arranged on guide arm mounting bracket 2, second fixed seat 42 is arranged on guide arm structure 3, second rotating shaft 43 is arranged on second fixed seat 42, one end of shock absorber 44 is rotatably arranged on first rotating shaft 41, the other end of shock absorber 44 is rotatably arranged on second rotating shaft 43, the end of guide arm structure 3 away from eyelet 32 is provided with connecting frame 61, air spring 6 is arranged on connecting frame 61, connecting plate 62 is arranged on the end of air spring 6 away from connecting frame 61, connecting plate 62 is arranged on support arm beam 1 away from the side of air spring 6, connecting frame 61 and support arm beam 1 are parallel state, reinforcing frame 5 is arranged on guide arm structure 3.

[0024] With this configuration, when the car needs shock absorption, the shock absorber 44 is placed on the guide arm mounting bracket 2 and the guide arm structure 3, forming a triangle between the guide arm mounting bracket 2, the guide arm structure 3, and the shock absorber 44. During shock absorption, the shock absorber 44 abuts against the guide arm mounting bracket 2 to limit the vibration of the guide arm structure 3. At the same time, the air spring 6 provides secondary shock absorption. Meanwhile, the air spring 6 is set in a parallel state between the connecting frame 61 and the support beam 1, which facilitates the application of force direction and increases the efficiency of the air spring 6. The reinforcing frame 5 facilitates the reinforcement of the bearing capacity of the guide arm structure 3. Thus, the triangular structure can effectively transmit and disperse the impact force and vibration from the road surface. During the damping process, the shock absorber 44 abuts against the guide arm mounting bracket 2, limiting the vibration of the guide arm structure 3, thereby reducing the impact of irregular vibrations on the vehicle body. The shock absorber 44, by abutting against the guide arm mounting bracket 2 during damping, can effectively limit the vibration of the guide arm structure 3. This design allows the shock absorber 44 to more precisely control the vehicle's movement, reducing unnecessary swaying and bouncing. Through the synergistic effect of the shock absorber 44 and the guide arm, the impact energy from the road surface can be absorbed and dissipated more effectively. This synergistic effect improves the overall efficiency of the damping system, allowing the vehicle to... Maintaining a stable driving state under various road conditions, the air spring 6 absorbs shocks by compressing air, exhibiting excellent flexibility and adjustability. During shock absorption, the air spring 6 can automatically adjust its stiffness and damping according to different road conditions and load conditions, providing the best shock absorption effect. In the parallel state, the force direction of the air spring 6 is consistent with the force direction of the support beam 1, which can more effectively transmit and utilize force. This design reduces force loss and improves the overall efficiency of the shock absorption system. The reinforcing frame 5 enhances the load-bearing capacity of the guide arm structure 3 by increasing the structural stiffness and stability. This design enables the vehicle to maintain good shock absorption and handling even under heavy load conditions.

[0025] In some embodiments, please refer to the following: Figs. 1-3 An auxiliary damping assembly 7 is also provided on the guide arm rotation shaft 31. The auxiliary damping assembly 7 includes a damping element 72, an abutment plate 71, a transmission plate 73, and a third mounting seat 74. The third mounting seat 74 is mounted on the transmission plate 73 and is rotatably mounted on the guide arm rotation shaft 31. The abutment plate 71 is mounted on the guide arm mounting bracket 2. The damping element 72 includes a damping cylinder 721 and a damping spring 722. One end of the damping cylinder 721 is mounted on the abutment plate 71, and the other end of the damping cylinder 721 is mounted on the transmission plate 73. The damping spring 722 is sleeved on the damping cylinder 721. One end of the damping spring 722 abuts against the abutment plate 71, and the other end of the damping cylinder 721 abuts against the transmission plate 73. An abutment pad 75 is provided on the end of the transmission plate 73 away from the damping spring 722.

[0026] With this configuration, when the air spring 6 is pressed down during high-intensity shock absorption, the guide arm structure 3 undergoes a slight downward deformation. At the same time, the guide arm structure 3 abuts against the abutment pad 75 on the transmission plate 73 and rotates around the guide arm rotation shaft 31, pressing against the shock absorption cylinder 721 and the shock absorption spring 722, thus mitigating the damage to the guide arm structure 3 during the entire process. Thus, when the air spring 6 is pressed downwards, the slight deformation and rotation of the guide arm structure 3 can effectively disperse the impact force from the road surface. This design ensures that the impact force is no longer concentrated at a single point, but is evenly distributed to the damping cylinder 721 and the damping spring 722 through the deformation and rotation of the guide arm structure 3, thereby reducing stress concentration in a single component. The process of the guide arm structure 3 rotating and pressing against the damping cylinder 721 and the damping spring 722 is actually an energy absorption and conversion process. Through this design, the impact force is converted into the rotational kinetic energy of the guide arm structure 3 and the elastic potential energy of the damping components, thereby effectively absorbing and dissipating the impact energy. During the damping process, the guide arm structure 3, through the interaction between the contact pad 75 and the transmission plate 73, and its rotation around the rotation axis, can... This design effectively reduces direct impact on the shock absorber cylinder 721 and shock absorber spring 722, reducing wear on key components and extending their service life. The deformation and rotation of the guide arm structure 3 make the damping process more gradual and smooth. This gradual damping can better adapt to different road conditions and driving conditions, providing a smoother and more comfortable ride. While absorbing impact, the deformation and rotation of the guide arm structure 3 also improves the structural rigidity of the entire suspension system. This enhanced rigidity allows the vehicle to maintain better stability and handling during high-speed driving or emergency braking. Through optimized design and material selection, the durability of the guide arm structure 3 and its related components has been significantly improved. This improvement is not only reflected in the damping effect but also in the overall durability of the entire suspension system.

[0027] The implementation principle of an automotive air spring guide arm according to an embodiment of this application is as follows: During the process of vehicle shock absorption, the shock absorber 44 is set on the guide arm mounting bracket 2 and the guide arm structure 3, forming a triangle between the guide arm mounting bracket 2, the guide arm structure 3 and the shock absorber 44. During shock absorption, the shock absorber 44 abuts against the guide arm mounting bracket 2 to limit the vibration of the guide arm structure 3. At the same time, the air spring 6 provides secondary shock absorption. Meanwhile, the air spring 6 is set in a parallel state between the connecting frame 61 and the support beam 1, which facilitates the application of force direction and increases the efficiency of the air spring 6. The reinforcing frame 5 facilitates the reinforcement of the bearing capacity of the guide arm structure 3. During high-intensity shock absorption, when the air spring 6 presses downward, the guide arm structure 3 undergoes a slight downward deformation. At the same time, the guide arm structure 3 abuts against the abutment pad 75 on the transmission plate 73 and rotates around the guide arm rotation shaft 31, pressing against the shock absorber cylinder 721 and the shock absorber spring 722, thus mitigating the damage to the guide arm structure 3 during the entire process.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
