The application characteristics of the outer dowty retarder

(1) The outer dowty retarder does not contact the wheel flange, and does not grind the wheel flange of the locomotive, reducing the workload of washing and repairing the locomotive and avoiding the trouble of the locomotive department.

(2) The lateral force generated by the inner dowty retarder on the wheels is to the outside of the rail, the cart wheels to the outside of the rail, and the outer item is the cart wheel to the rail, the cart wheel to the outside of the rail, and the outer item is the cart wheel to the rail

(3) The outer dowty retarder is installed on the outer side of the rail, and the slag in the pillow part is less than the slag in the sleeper groove on the inner side of the rail, so the installation is very convenient. At the same time, the speed dowty retarder is on the outside of the rail, which is relatively convenient for maintenance personnel to disassemble and assemble.

(4) Since the outer dowty retarder is the contact between the wheel tread and the cylinder of the deceleration roof, and the inner roof is in contact with the wheel flange, the working stroke of the outer dowty retarder cylinder is smaller than that of the inner roof, so the braking work is smaller than that of the inner dowty retarder . Although the stroke is smaller than that of the inner top, the braking power is smaller than the inner top, although
