A device designed to bridge the gap between vehicles equipped with air brake systems and trailers utilizing electric brakes allows for synchronized and effective braking. This system converts pneumatic pressure from the towing vehicle’s air lines into an electrical signal, which then activates the trailer’s electric brakes proportionally to the braking force applied by the driver. For instance, a semi-truck using its air brakes can effectively control a smaller trailer equipped with electric brakes, ensuring consistent deceleration.
The adoption of these conversion systems is pivotal for safety and regulatory compliance in mixed fleet operations. By enabling the safe and controlled towing of electrically braked trailers by vehicles with air brake systems, it mitigates the risk of jackknifing or trailer sway, improving overall road safety. Historically, this technology has evolved to address the challenge of compatibility between different braking systems, leading to more versatile and adaptable towing solutions.
