Disc Suspension Axle

Technical Field

The utility model belongs to the technical field of vehicles, and more particularly relates to a disc suspension axle for semi-trailers.

Background Art

In the prior art, semi-trailers generally adopt drum-type suspension axles. However, such drum-type suspension axles suffer from poor resistance to thermal fade and water fade, as well as poor braking stability. In addition, significant noise is generated during braking. The instantaneous braking noise can reach up to 110 decibels in severe cases, which constitutes serious noise pollution.

Summary of the Invention

To address the above problems, the utility model provides a disc suspension axle with a simple structure.

The disc suspension axle comprises a connecting flange, brake caliper, brake disc, brake actuator, and axle. The key feature is that connecting flanges are arranged at both ends of the axle, brake discs are arranged on the inner sides of the connecting flanges, and a pair of brake actuators is arranged at the middle of the axle. The brake actuators are connected to the brake discs through brake calipers.

Beneficial Effects

The utility model has the following advantages:

Excellent resistance to thermal fade

Excellent resistance to water fade

Improved braking stability

Brake pads of the disc brake are easier to replace and maintain compared to those of drum brakes

Lower maintenance and operating costs

Significant reduction in braking noise
