Embodiment 1

[0031] Such as image 3 and Figure 5 As shown, the suspension system 100 of the trailer in this embodiment is a four-axle suspension.

[0032] The suspension system 100 includes: two symmetrically arranged sub-suspension systems 101, each sub-suspension system 101 includes a plurality of leaf springs sequentially connected along the length direction of the vehicle body, and the width of each leaf spring is 90mm. According to the front and rear arrangement of the vehicle body, they are respectively: the front leaf spring 21 , the first middle leaf spring 31 , the second middle leaf spring 32 and the rear leaf spring 41 . Wherein, the center distance of the rear leaf spring 41 of the suspension system 100 is smaller than the center distance of the front leaf spring 21, and the center distance of the first middle leaf spring 31 is the same as the center distance of the front leaf spring 21, and the center distance of the second middle leaf spring 32 The center-to-center distan...

Embodiment 2

[0049] Such as Figure 8 and Figure 9 As shown, the structure of the suspension system 100 of the trailer in this embodiment is roughly the same as that in Embodiment 1, except that the suspension system 100 of the trailer in this embodiment is a five-axis suspension.

[0050] That is to say, in this embodiment, the middle leaf spring further includes a third middle leaf spring 33 . The third middle leaf spring 33 is connected to the second middle leaf spring 32 and the rear leaf spring 41 respectively. Correspondingly, the third middle leaf spring 33 and the rear leaf spring 41 are connected to each other by adding a fourth balance arm 54 , and the fourth balance arm 54 is connected to the longitudinal beam 11 of the trailer through the fourth middle spring bracket 65 . The connecting structure of the third middle leaf spring 33, the second middle leaf spring 32 and the rear leaf spring 41 is the same as that of the front leaf spring 21 and the first middle leaf spring 31,...

Abstract

The invention provides a trailer and a suspension system thereof. The suspension system of the trailer is disposed under a frame. The suspension system comprises two sub-suspension systems symmetrically arranged about the center line of the frame, and each sub-suspension system includes a plurality of leaf springs sequentially connected in the length direction of a trailer body front and back. Themultiple leaf springs are the front leaf spring, at least one middle leaf spring and the rear leaf spring which are arranged front and back. The center distance of the rear leaf spring in the suspension system is less than the center distance of the front leaf spring. According to the suspension system of the trailer, the rear leaf spring is shrunk towards the center line of the frame, installation space and conditions are provided for installation of a self-steering axle, and the use is more convenient.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a heavy-duty multi-axle trailer and its suspension system. Background technique [0002] In many foreign countries, multi-axle trailers with four or more axles are required for heavy loads, and trailers with four or more axles are also required for the in-factory turnover of many heavy goods in China. However, if the conventional four-axle or above leaf spring balanced suspension system is adopted, the trailer tires will be severely worn, the steering resistance will be large, the driving stability will be poor, and the maintenance cost will remain high. In order to reduce tire wear and reduce maintenance costs, the rear two axles or the rear three axles are usually self-steering axles. For the conventional multi-axis leaf spring balanced suspension system, the installation distance of the front and rear axle leaf springs 2' is the same, and the self-steering axle cannot be install...
