Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention discloses a welded type pilot arm for an air suspension, comprising: the air bag type air bag bridge comprises a guide arm body 1, an upper supporting plate 2, a lower supporting plate 3 and an air bag mounting support 4, wherein the upper supporting plate 2 is welded at the bottom end of the guide arm body 1, the lower supporting plate 3 is welded at one side of the air bag mounting support 4, and the upper supporting plate 2 and the lower supporting plate 3 are connected through a connecting assembly and are finally welded on a bridge rod 8.
The lower supporting plate 3 and the air bag mounting seat 4 are offset by an angle of 20 degrees. The top end of the air bag mounting support 4 is provided with an air bag 5, and the top end of the air bag 5 is connected to the longitudinal beam 6. The bottom end of the longitudinal beam 6 is fixedly connected with a guide arm support 7, one end of the guide arm body 1 is rotatably connected with the guide arm support 7, and the other end of the guide arm body is welded with the upper supporting plate 2. And a bridge rod 8 is arranged between the upper supporting plate 2 and the lower supporting plate 3 and is fixed through a connecting assembly, and the upper supporting plate 2 and the lower supporting plate 3 are finally welded on the bridge rod 8. The connecting assembly comprises a fastening bolt 9 and a locking nut 10 which are matched with each other.
In this embodiment, the guiding arm body 1 with the material of gasbag installing support 4 is Q345, the layer board 2 with the layer board 3 material is QT 600.
The traditional guide arm structure is characterized in that the air bag 5 is arranged at the guide arm and is not arranged at the center of the guide arm, the air bag 5 is prone to being damaged due to stress deviation, and the uneven stress of the guide arm influences the compatibility of the air-raid suspension assembly and the service life of the guide arm. The structure of the invention is a welding type, which is different from the traditional integral forging type, and the weight of a single guide arm is greatly reduced while the integral strength is ensured, and the weight of the single guide arm is at least 30Kg lighter; the upper supporting plate 2 and the guide arm body 1 are welded into a whole, and the lower supporting plate 3 and the air bag mounting support 4 are welded into a whole, so that the coordination of the air suspension assembly is effectively ensured; the lower supporting plate 3 and the air bag mounting support 4 are welded into a whole, the air bag mounting support 4 deviates a certain angle, and when the air bag 5 is mounted, the air bag 5 is always in the center of the lower supporting plate 3, so that the air bag 5 is uniformly stressed, and the service life is greatly prolonged.
The invention relates to a split welding type guide arm. The traditional guide arm is an integrated guide arm made of spring steel, the body is heavy, the coordination is poor, and the stress of the air bag is uneven. The invention relates to a split welding type guide arm. According to the invention, the guide arm body and the upper supporting plate are welded into a whole, the lower supporting plate and the air bag mounting support are welded into a whole, the guide arm body and the upper supporting plate are fixed on the bridge rod by the fastening bolt and the locking nut and are finally welded on the bridge rod, as shown in figure 2, the coordination of the air suspension assembly is effectively ensured.
