Anti Lock Air Brake Systems

Anti lock braking system when nhtsa regulations requiring trailer anti locking braking systems abs went into effect in 1998 haldex had already been producing trailer abs for over 25 years.

Anti lock air brake systems.

To understand how abs works it is important to look first at the components that make up the system. The key part of semi trailer. The system functions with the air brake system that is found in heavy duty trailers abs ensures that wheels maintain their contact with the ground when the driver applies the braking system. Speed sensor tracks the rotational speed of the car s wheels and determines whether it is accelerating or decelerating.

The difference of course is air brakes compared to hydraulic brakes. Air brake abs or antilock brake systems are similar to automotive in principle with wheel sensors tone wheels and a control module. Anti lock braking system abs is an electronic safety system that controls and monitors wheel speed when brakes are applied. The brake fluid in the accumulator is used for providing power assist pressure modulation during an abs stop and in some systems to apply the rear brakes.

Air brake systems is an authorised distributor for most of the world s leading brands including wabco bendix haldex sealco midland knorr bremse kongsberg and fte. The results using this system during winter conditions are quite amazing. Our aim is to meet any of our customer s needs and offer a fast and efficient service. On our newer school buses there is an off road switch on the dash to engage the abs and reduce wheel spin.

The pump motor is responsible for filling the accumulator and is controlled by a pressure switch. It is also known as an anti skid braking system. Today abs and electronic brake system ebs equipped trailers haul freight all over the world providing controlled safe stopping.

So how do anti lock brake systems work. The brake fluid has a lot to do with controlling the braking pressure within an anti lock braking system. Valves regulate the air pressure applied on the brakes when the abs is. Sometimes there could be a leak from this reservoir which will cause the fluid levels to drop.
