Actuation member for a proportioning valve for load leveling applications

摘要

A proportioning valve actuation member (110) for a vehicle (12) having a braking system and a load leveling system has an actuator (22) mounted between the proportioning valve (20) of the braking system and the rear suspension (14) of the vehicle (12). The actuator (22) is operative to increase the amount of braking applied to the rear wheels in response to the movement of the rear suspension (14). The actuation member (110) further includes an activation cylinder (112) which is placed in parallel with the actuator (22) and is in communication with the load leveling system. When the load leveling system activates to correct the attitude of the vehicle (12), the activation cylinder (112) is also signaled to correct the reading provided to the proportioning valve (20) by the actuator (22).
