Product Overview

Products Description

In the modern transportation industry, the suspension system acts as a crucial link between the chassis and the vehicle frame. It not only supports the vehicle’s weight, braking force, and driving force but also plays an essential role in mitigating road impacts and ensuring smooth travel. For semi-trailers that require substantial load-bearing capabilities, selecting an outstanding non-independent suspension system is particularly critical.

Typically, Kales 66 series American type Leaf Spring Suspension has a single axle capacity of 10 tons. The number of semi-trailer axles is available in 1, 2 or 3 axle configurations. Optional conventional leaf spring sizes include 77×13-9L and 77×13-10L, while parabolic leaf springs are 77×22-3L. The suspension’s equalizer bushings and torque arm bushings are tapered rubber bushings.

Tailored for semi-trailers, Kales 66 series American type Leaf Spring Suspension integrates the reliability of traditional leaf spring suspensions with the advancements of innovative technology. With its superior performance and dependability, it stands out as the ideal choice for your semi-trailer suspension needs. Compared to other types of suspensions such as rigid axles, single-point suspensions, and air suspensions, Kales offers distinct advantages:

【Selection of Premium Materials】

The Kales steel leaf spring suspension uses high-quality silicon-manganese spring steel, which offers greater strength, elasticity, and hardenability. This means we can provide a lighter weight while maintaining load capacity, leading to increased stability when carrying heavy loads and reduced fuel consumption for maximum economic efficiency.

【Ease of Installation and Maintenance】

Our suspension system features a simple structure that is easy to install and maintain. Whether at a busy logistics center or along distant transport routes, Kales steel leaf spring suspensions allow for quick replacement and maintenance, minimizing downtime and enhancing operational efficiency.

【High-Strength Heat Treatment】

Through high-strength heat treatment, Kales steel leaf spring suspensions maintain high strength while increasing product toughness. This results in significant strengthening, allowing our suspension systems to perform excellently even under harsh road conditions, providing long-term reliability.

【Outdoor Protective Treatment】

Kales steel leaf spring suspensions are coated with outdoor rust-resistant paint, effectively isolating moisture, preventing oxidation, and protecting against corrosion, thus extending service life. Regardless of whether you’re operating in humid coastal areas or dusty desert regions, Kales ensures the durability of your suspension system.

【Lightweight Design】

In the commercial vehicle sector, “lightweight” has become a buzzword. By optimizing design and reducing the number of spring leaves without compromising load capacity, Kales achieves a perfect balance between lightweight construction and load-bearing capability. This not only decreases the vehicle’s own weight but also improves fuel efficiency, offering a competitive edge for your transportation business.

Choosing Kales steel leaf spring suspension means opting for a powerful, reliable, and economical partner. Together, let’s safeguard your transportation endeavors. Upgrade your semi-trailer suspension system now and experience the superior performance and economic benefits brought by Kales.
