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 application.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the vehicle of the present invention, which is an 8 × 2 vehicle, includes four axles, that is, four pairs of wheel axles, wherein the third axle is a driving axle, and the fourth axle is a liftable rear axle. Both the third and fourth bridges are equipped with air suspensions. Both the third and fourth bridges are thus equipped with a stabilizer bar arrangement. In the stabilizer bar structure of the fourth bridge, the ends of the two arms of the stabilizer bar assembly 1 need to be bent to adapt to lifting and lowering.

It will be appreciated that the first axle fitted with leaf spring suspension may also be fitted with a stabilizer bar arrangement in an embodiment of the transverse invention in order to better increase the load carrying capacity and the resistance to overturning.

On the other hand, as shown in fig. 1, 3, 4, 5 and 6, the present invention also provides a stabilizer bar structure comprising: two bottom plates 4, which are used for being fixedly connected with the axle of the automobile; the stabilizer bar assembly 1 is U-shaped and comprises a bottom and two arms extending along two ends of the bottom, and the two arms are respectively connected and fixed with the bottom plate 4; the suspension rod support assemblies 2 are connected with the breadth and the lower wing surface of the automobile longitudinal beam, each suspension rod support assembly 2 comprises a first connecting surface 22 used for being connected and fixed with the breadth of the automobile longitudinal beam and a second connecting surface 23 used for being connected with the lower wing surface of the automobile longitudinal beam, and the second connecting surface 23 extends downwards vertically to form a first connecting part 24; two jib assemblies 3, two 3 one end of jib assembly is used for being connected with first connecting portion 24, is equipped with on the other end to be used for the cover to establish the through-hole of stabilizer bar assembly 1's bottom.

In some embodiments, the two arm end portions of the U-shape of the stabilizer bar assembly 1 are bent again to form the bent portion 11, and the bent portion 11 is connected to the base plate 4. Such solutions are specifically directed to the design of the lifting bridge of the liftable air suspension. As shown in fig. 1 and 2, an air bag for lifting the rear axle is added to the air suspension of the fourth axle. The stabilizer bar assembly 1 with the bending part 11 can be matched with the change of the fourth bridge when the fourth bridge is lifted, and the bending angle of the bending part 11 needs to be designed after checking according to the parameters of each part of the whole vehicle and the relative motion track of each part.

Preferably, the first connecting surface 22 of the boom seat assembly 2 is provided with a first set of bolt holes 21. The first group of bolt holes 21 is used for being fixedly installed with the breadth of the automobile longitudinal beam. The suspender support assembly 2 is simultaneously fixed with the side surface and the lower airfoil surface, which is beneficial to improving the integral strength of the frame assembly, and the fixing holes are concentrated, thereby effectively preventing the frame from cracking.

For the purpose of saving weight and material, the first set of bolt holes 21 may be four raised bolt holes on the first connection surface 22, instead of punching holes on the original first connection surface. The boom support assembly 2 may thus be a cast part with greater strength and precision than conventional stamped parts, and thus is designed for two purposes.

It should be noted that the bottom plate 4 includes a main body portion 41, one end of the main body portion 41 extends outward to form a second connecting portion 42, and the second connecting portion 42 is used for being fixedly connected with the stabilizer bar assembly 1, and the second connecting portion 42 is designed in such a way that the main body portion 41 is fixed to the axle, and if the stabilizer bar assembly 1 is directly connected, the stabilizer bar assembly may interfere with the axle, so that the mounting position of the stabilizer bar assembly 1 can be automatically adjusted according to the shape of the axle after the second connecting portion 42 is installed.

Specifically, the main body portion 41 is a substantially rectangular parallelepiped member, and at least two mounting holes 43 are provided in the rectangular parallelepiped member, and the mounting holes 43 are used for inserting U-bolts.

Preferably, four mounting holes 43 are formed at four corners of the rectangular surface of the bottom plate 4, and the mounting holes 43 are used for penetrating U-shaped bolts to fix the axle.

It should be noted that the main body 41 of the bottom plate 4 shown in fig. 6 has two mounting holes 43 on the same side, and an extension part slightly higher than the rectangular surface of the main body 41 is defined between the two mounting holes 43, and the extension part is used for limiting the vehicle axle and preventing the vehicle axle from moving in the direction when the extension part is in a fixed mounting position with the vehicle axle.

Preferably, the main body 41 is opened with at least one hollow hole 44 at the center, and it can be seen from fig. 6 that the hollow holes 44 are arranged in plurality, which is to reduce the weight of the components for the purpose of lightening the weight of the automobile.

Further, the tail ends of the two arms of the stabilizer bar assembly 1 are provided with small holes, and the tail ends with the small holes are inserted between the two bottom plate holes and are simultaneously connected with the two bottom plate holes through bolts.

It can be understood that four fastening bolt holes are further provided around the through hole of the boom assembly 3, and the fastening bolt holes are used for fixedly connecting the boom assembly 3 and the stabilizer bar assembly 1. The stabilizer bar assembly 1 and the suspender assembly 3 are better fixedly connected together through the connection.

In some embodiments, the first connecting portion 24 is provided with a connecting hole 25; the boom assembly 3 is provided with two third bolt holes 31 arranged at intervals, the connecting hole 25 is positioned between the two third bolt holes 31, and the three can be simultaneously connected and fixed together through one bolt.

In view of the above, the present invention has found that an automobile equipped with an air suspension lift bridge, similar to an 8 × 2 automobile, has a problem of lateral overturning, and thus provides an air suspension stabilizer bar structure and an automobile. The special transverse stabilizer bar is additionally arranged on the air suspension of the third axle (driving axle) and the fourth axle (lifting axle) in the four axles of the automobile, so that the problem of insufficient lateral rigidity of the air suspension is solved. Simultaneously, through fixing stabilizer bar in the breadth and the lower wing face department of longeron, strengthened its bulk strength, reduced the risk of frame fracture.
