A braking device for vehicle wheels, comprising at least a revolving brake disc (11 ) connected to at least a wheel (10) or its spin axis, as well as a first floating brake calliper (13) and second floating brake calliper (13' ), moving angularly to the brake disc (11 ). The first and the second floating brake callipers (13, 13' ) can be activated alternately so as to engage the brake disc (11 ) one after the other and generate a continuous and unidirectional rotation of said brake disc (11 ) and the wheel it is associated with. The floating brake callipers (13 and 13' ) constituting in addition braking means interacting with said brake disc (11 ). |
