The yoke trailing arm beam design allows the brake actuator to be placed under the tail without changing the normal frame transition geometry. This design is compatible only with Wabco PAN 22 or Haldex ADB.
The newly designed yoke trailing arm has a “banana beam” that allows the brake actuator to be tucked between the beam and trailer frame when brake actuator ground clearance and protection are critical. This design requires a more “squared-off” frame transition to allow clearance for the actuator.
