Two-Axle Reverse-Mounted Axle Suspension Device

Technical Field

This utility model relates to the field of vehicle technology, and more specifically to a two-axle reverse-mounted axle suspension device for semi-trailers.

Background Technology

In the existing technology, semi-trailer suspensions generally adopt a single-axle forward-mounted axle suspension. Such configurations have limited load capacity and result in a higher overall vehicle height. This not only makes loading and unloading inconvenient but also increases transportation costs.

Summary of the Invention

To address the above issues, the present utility model provides a two-axle reverse-mounted axle suspension device.

The device comprises a front bracket, front connecting rod, fixing bolts, leaf spring, middle bracket, rear connecting rod, frame, rear bracket, front axle, equalizing bracket, and rear axle.

The key feature is that:

A front bracket is arranged on the lower front side of the frame

A rear bracket is arranged on the lower rear side of the frame

A middle bracket is arranged on the lower middle portion of the frame

Leaf springs are arranged between the front bracket and middle bracket, and between the middle bracket and rear bracket

A front axle is arranged between the front bracket and middle bracket

A rear axle is arranged between the middle bracket and rear bracket

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

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

An equalizing bracket is arranged at the middle portion of the middle bracket

Further Features

The front axle is arranged above the leaf spring and fixed by fixing bolts

The rear axle is arranged above the leaf spring and fixed by fixing bolts

Beneficial Effects

The two-axle reverse-mounted axle suspension device offers:

Higher load capacity

Lower overall vehicle height

Easier loading and unloading

Reduced transportation costs
