Three-Axle Forward-Mounted Axle Suspension Assembly

Technical Field

This utility model belongs to the field of vehicle technology, and more specifically relates to a three-axle forward-mounted axle suspension assembly for heavy-duty semi-trailers.

Background Art

In the prior art, semi-trailer suspensions generally adopt single-axle or dual-axle forward-mounted axle suspension structures. However, vehicles equipped with such configurations have relatively low load capacity and higher transportation costs, resulting in significant economic losses for transport enterprises.

Summary of the Invention

To address the above problems, the utility model provides a three-axle forward-mounted axle suspension assembly.

The assembly comprises a front bracket, frame, leaf springs, front inner bracket, front equalizing bracket, rear inner bracket, rear equalizing bracket, rear bracket, front connecting rod, front axle, middle connecting rod, middle axle, rear connecting rod, and rear axle.

Its key features are as follows:

A front bracket is arranged on the lower front side of the frame, and a rear bracket is arranged on the lower rear side of the frame.

A front inner bracket is arranged on the inner side of the front bracket, with a front equalizing bracket located at its middle portion.

A rear inner bracket is arranged on the inner side of the rear bracket, with a rear equalizing bracket located at its middle portion.

Leaf springs are respectively arranged between:

the front bracket and the front inner bracket,

the front inner bracket and the rear inner bracket,

the rear inner bracket and the rear bracket.

A front axle, middle axle, and rear axle are respectively arranged below the leaf springs in the above three sections.

A front connecting rod is arranged between the front bracket and the front axle.

A middle connecting rod is arranged between the front inner bracket and the middle axle.

A rear connecting rod is arranged between the rear inner bracket and the rear axle.

Beneficial Effects

The three-axle forward-mounted axle suspension assembly provides high load capacity and reduced transportation cost.
