Vehicle has several protrusions formed in roadway side surface of brake disc and engaged with road surface when braking device is activated

摘要

The vehicle has a braking device (1) comprising a vehicle inflatable element (3) that is arranged on the vehicle underside and expandable from an idle state. The braking effect is achieved by the braking device in the expanded active state of the inflatable element. The brake disc (4) is pressed by the inflatable element in the expanded active state, in the direction of a road surface (9). Several protrusions (8) are formed in the roadway side surface of the brake disc and engaged with the road surface when brake device is activated.
