Abstract: A braking-stopping unit for the defined stopping and braking of a manually operable command issuer for ship's drives includes an external rotor with a circular opening forming a bearing ring and an inner rotor arranged in the opening, which are arranged in a rotationally movable manner relative to each other. One of the two rotor elements is statically fixed in its position and the other rotor element is designed either with a manually operable actuator or constructed so as to be connectable to such an actuator. The inner rotor includes at least three spring arms which are radially arranged in the circumferential direction, wherein said spring arms can be pushed into a respective recess arranged in the outer surface of the inner rotor. The spring arms act in each case radially non-positively on the running surface of the bearing ring via the braking and stopping means.

Abstract: A land vehicle in the form of a wheeled semi-trailer and thereon (e.g., a braking device) is provided with an on-board energy having a consumer of energy providing device which is driven, through a controlling apparatus by a compressed air supply or by a flexible drive shaft arrangement connected to a wheel of the semi-trailer.
