Method used

Traditional guide arm structure is that air bag 5 is installed in guide arm place and is not in guide arm center, and stressed offset, easily damages air bag 5, makes guide arm stressed uneven influence air raid suspension assembly coordination and guide arm service life . The structure of the present invention is a casting type, which is different from the traditional integral forging type. While ensuring the overall strength, the weight of a single guide arm is greatly reduced, and the weight of a single guide arm is at least 30Kg; and the upper supporting plate 2 and the guide arm body 1 is cast as a whole, and the lower support plate 3 and the guide arm support 4 are cast as a whole, which effectively ensures the coordination of the air suspension assembly; the airbag installation support 4 is offset by a certain angle, and when the airbag 5 is installed,...

Abstract

The casting type guide arm comprises a guide arm body, an upper supporting plate, a lower supporting plate and an air bag mounting support, the upper supporting plate is located at the bottom end of the guide arm body and integrally cast with the guide arm body, and the lower supporting plate is located on one side of the air bag mounting support and integrally cast with the air bag mounting support. The upper supporting plate and the lower supporting plate are connected through a connecting assembly. The structure is of a casting type and is different from a traditional integral forging type, and the weight of a single guide arm is greatly reduced while the integral strength is guaranteed; the upper supporting plate and the guide arm body are cast into a whole, and the lower supporting plate and the guide arm support are cast into a whole, so that the coordination of the air suspension assembly is effectively ensured; the air bag mounting support has a deviation angle, so that when the air bag is mounted, the air bag is always in the center of the lower supporting plate, the air bag is uniformly stressed, and the service life is greatly prolonged.

Example Embodiment

[0019] Order that the invention object, technical solutions, and advantages of the embodiments more clearly below in conjunction with the present invention in the accompanying drawings, technical solutions in the embodiments will be apparent to the present invention, completely described, obviously, the described embodiments some embodiments of the present invention rather than all embodiments. Based on the embodiments of the present invention, all other embodiments of the present embodiment of ordinary skill in the art without any creative effort shall fall within the scope of the present invention.

[0020] Reference Figure 1-2 The present invention discloses an air guide arm type suspension of a casting, comprising: a guide arm body 1, the pallet 2, the pallet 3 and the airbag mounting bracket 4, the pallet 2 is positioned on the bottom end of the guide arm body 1 and the cast guide arm body 1 integrally, the pallet 3 is located in the side airbag is mounted in the support 4, and the airbag integrally cast mounting bracket 4, the pallet 2 and the lower connection assembly 3 is connected to the pallet and the final rod 8 welded to the bridge.

[0021] The lower mounting bracket pallet 3 is offset an angle between 4 and 20 ° to the airbag. The airbag mounting seat 4 is mounted to the top of the airbag 5, the airbag 5 to the top 6 is connected to the side members. The stringer 6 is connected to the bottom end of the fixed guide bracket arm 7, one end of the guide arm and the guide body 7 rotatably connected to the arm support, and the other end connected to the pallet 2 is integrally cast. The pallet 2 provided with a bridge between the pallet 3 at 8 bar, and is fixed by the connection assembly, and the pallet 2 and the pallet bridge 3 in the final weld rod 8. Said connection assembly includes cooperating fastening bolt 9 and the lock nut 10.

[0022] In this embodiment, there is an additional arm on the side wall guiding the body reinforcing rib structure 11. The guide arm body frame as "King", increased side rib structure, the overall stability of the carrying ability.

[0023] In this embodiment, the guide arm body 1, the pallet 2, the pallet 3 and 4 the airbag mounting bracket are made of QT600.

[0024] Traditional airbag guide arm structure 5 is mounted on the guide arm is not at the center of the guide arm, the force offset, fragile balloon 5, the guide arm uneven stress affect coordination of the suspension assembly and the guide arm raid service life. Structure of the present invention is a cast type, with conventional integrated forged different type, ensuring at the same time the overall strength of such a single guide arm greatly reduce the weight, a single light guide arm by weight of at least 30Kg; pallet 2 and the upper guide arm and the body 1 is integrally cast, and the guide arm 3 and the pallet support 4 integrally cast, effectively guarantee the coordination of air suspension assembly; airbag angularly offset mounting bracket 4, 5 mounted in the airbag, the airbag to ensure 5 3 always lower center of the pallet, the balloon 5 uniform force, greatly increase the service life.

[0025] The present invention is a split-type casting guide arm and carrying capacity. Traditional guide arm a spring steel production style guide arms, heavy body, poor coordination, airbag discontinuity, such as figure 2. The present invention is a split type guide arm cast. The present invention is cast on the guide arm and cast as an integral pallet, the pallet with the airbag integrally cast mounting bracket, a fastening bolt with a lock nut and both the fixed rod bridge, the bridge and ultimately welding rod on, effectively ensuring the coordination of air suspension assembly.

[0026] The present invention is an airbag with an offset angle of the mounting bracket. Conventional structure of an airbag mounted on the guide arm is not at the center of the guide arm, the force offset, fragile balloon, the guide arm uneven stress affect coordination of the suspension assembly and the guide arm raid service life, such as figure 2 Indicated. The present invention is an airbag mounting bracket mounted at an offset angle with balloon, the balloon always ensure that the lower center of the pallet, the airbag uniform force greatly increase the service life.

[0027] Guide arm bracket welded to the side members. The guide body and the arm are integrally cast on the carrier, called the upper points. The airbag mounting bracket integrally cast with the lower pallet, called a lower portion. One end of the shaft portion by a bolt attached to the guide arm support (rotatable about the axis of the bolt), the other end of the lower portion of the bolt rod fixed to the bridge, and finally welded to the rod by the bridge. And the other end coupled to the lower portion by a bolt airbag, the airbag and the other end is fixed to the side member by a bolt.

[0028] An bridge pole wheel, when passing over bumps, the wheel guide rod and the bridge with the lower guide arm about the arm support shaft bolt in relief, this time in the air suspension air bag to shrink or stretch to filter out jitter, so that the body running smoothly.

[0029] Finally, it should be noted that: the above embodiments are intended to illustrate the present invention, rather than limiting;. Although the embodiments of the present invention has been described in detail, those of ordinary skill in the art should be understood: that they may still to the technical solutions described in each embodiment to modify, or to some technical features equivalents; as such modifications or replacements do not cause the essence of corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
