ABSTRACT:
In accordance with the present invention, a hand brake assembly (300) is mounted adjacent one end of a first car or articulated unit (303). A force dividing assembly (306) is provided on the first car, which divides the applied hand brake into a first (313) and second (321) hand brake linkages. The first hand brake linkage (313) is connected to a first air brake linkage (315) located on the first car. Preferably a portion of the first air brake linkage is located within an air brake cylinder (318). When the hand brake is applied, the first hand brake linkage (313) is effective to apply the brakes on the first car or unit through the first air brake linkage. The second hand brake linkage (321) extends from one car or unit to a second adjacent car or unit (333). A force multiplying assembly (324) is provided on the second car or unit which increases the hand brake force of the second hand brake linkage to a level sufficient to apply the brakes on the second car or unit through a second air brake linkage (336) located on the second car or unit. A second force dividing assembly (340) is located on the second car and another hand brake linkage (353) is connected thereto extend to a third car or unit 363 to apply the hand brake force on the third car or unit.
