Problems solved by technology

[0003] In order to meet the passability requirements and lower the loading center of gravity when many trailers are in use, the height of the trailer load-bearing surface from the ground is required to be reduced, which leads to the limitation of the height of the longitudinal beam above the suspension
The front spring bracket of this type of trailer and the upper longitudinal beam at the front side are often damaged due to too small height and insufficient strength

Embodiment 1

[0022] A kind of novel trailer suspension system structure of the present embodiment is two-axle suspension, such as figure 2 As shown, it has a front axle 131 and a rear axle 132 .

[0023] The trailer suspension system includes: the first support 121 of the front suspension, the second support 123 of the rear suspension, the first leaf spring 141, the second leaf spring 142, the first torsion bar 161, the second torsion bar 162, and the balance arm 170 and other parts. The balance arm 170 is arranged on the balance support 122 of the middle connection mechanism. The front end of the balance arm 170 has a front connection point 181 for connecting the first leaf spring 141, and the rear end of the balance arm 170 has a connection point 181 for connecting the second leaf spring 142. The rear end connection point 182 of the first leaf spring 141 is connected to the first support 121 at the front end, the rear end of the first leaf spring 141 is connected to the front end conne...

Embodiment 2

[0026] Such as image 3 As shown, a novel trailer suspension system structure of the present embodiment is a three-axle suspension, which has a front axle 331, a central axle 332 and a rear axle 333, and the central axle 332 is located at the middle of the frame longitudinal beam of the trailer. 331 and the central axis 332 .

[0027] The trailer suspension system includes: first support 321, front support 322, rear support 323 and second support 324, first leaf spring 341, third leaf spring 342, second leaf spring 343, first torsion bar 361 , the third torsion bar 362, the second torsion bar 363, the first balance arm 371, the second balance arm 372 and other components. The first balance arm 371 and the second balance arm 372 are respectively arranged on the supports 322, 323. The manner is the same as in the first embodiment. The installation methods of the first torsion bar 361 , the third torsion bar 362 and the second torsion bar 363 are also the same as those in the ...

Abstract

The invention relates to a novel trailer suspension system structure, which belongs to the technical field of suspension systems. The suspension system includes a front suspension, a rear suspension and a middle connection mechanism. The front suspension includes a first support, a first torsion bar and a first fixing assembly, and the first torsion bar is arranged on the first support and the first fixing assembly. The assembly is hinged between the two, and the first fixed assembly is fixedly connected to the leaf spring of the front suspension; the rear suspension includes the second support, the second torsion bar and the second fixed assembly, and the second torsion bar is set It is hinged between the middle connection mechanism and the second fixed assembly, and the second fixed assembly is fixedly connected to the leaf spring of the rear suspension; the middle connection mechanism includes a balance support, and the balance support is provided for connecting with each plate. A spring-connected balance arm assembly; the first support and the second support are respectively arranged at the boss at the front end and the boss at the rear end of the frame longitudinal beam of the trailer. The suspension system enhances the strength of the longitudinal beam of the vehicle frame under the premise of normal work.

Description

technical field [0001] The invention relates to a trailer suspension system structure, which belongs to the technical field of suspension systems. Background technique [0002] Such as figure 1 As shown in the figure, the conventional trailer leaf spring suspension system, the brackets welded with the frame are divided into front suspension, middle suspension and rear suspension according to different positions. The support contours of the front, middle and rear suspensions of the suspension system are at On the same installation plane, referred to as straight type, the longitudinal beam of the trailer above the suspension system is designed with the same height and equal strength. When the entire suspension system is stressed during the running of the trailer, a moment will be generated relative to the longitudinal beam, and the greater the moment arm from the center of the suspension system, the greater the moment will be generated. [0003] When many trailers are in use...
