Abstract

The device has a brake shoe (9) actuable through an operating lever (1) and adapted to be brought into operative contact with the tread of a tire (2) in such a manner that the brake device may be operated both as a wheel (travel) brake and a locking (parking) brake independently of the tire inflation pressure. The operating lever is connected to the brake shoe (9) through spring means (15) having characteristics, whereby if the tire pressure is reduced the spring means expands to maintain contact between the shoe (9) and tire (2)-the contact pressure is limited by virtue of the spring means. As shown, lever (1) has cam discs (28) acting via rollers (12) to move a cylinder (6) and hence a cylinder (7) -the spring means (15) comprising a stack of dish or cup springs (or coiled or helical springs) are provided between the ends of cylinders (6, 7). When the device acts as a locking brake, rollers (12) are seated in cutout (25) in cam discs (28). <IMAGE>
