Abstract
An anti-lock braking system for a triple axle trailer having three axles and six wheels is disclosed. The system includes a first wheel speed sensor coupled to the first wheel of the trailer, a second wheel speed sensor coupled to the third wheel of the trailer, a spring mount pivotably coupled to the body of the trailer, a first suspension member coupled to the first wheel and to the spring mount and a second suspension member coupled to the second wheel and to the spring mount. The system includes a hydraulic braking actuator having a first channel coupled to the first wheel and the second wheel and a second channel coupled to the third wheel. The spring mount pivots in response to an applied brake torque to increase a normal force applied to the second wheel as compared to a normal force applied to the first wheel.
