摘要： A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.

摘要： An electromechanical brake actuator (2) includes a housing (1), a first housing part (3) configured as a housing flange for attaching the electromechanical brake actuator (2) to a disc brake (38), a second housing part (4) for receiving a drive (6), a third housing part (5) arranged between the first housing part (3) and the second housing part (4) and connected to the first housing part (3) and the second housing part (4), a motor (37), a gearbox (7), and a tappet (9) or a spindle for actuating a disc brake (38). The housing (1) is an aluminum die-cast formed part. The first housing part (3) and the second housing part (4) have planar contact surfaces (34, 34a) configured to receive plates of a two-plate die-casting machine during the forming process of the housing (1).

摘要： A brake carrier for receiving brake pads for a disc brake with a brake disc includes a clamping-side bridge strut on a clamping side of the disc brake, and a reaction-side bridge strut on a reaction side of the disc brake arranged parallel to a brake carrier axis. The clamping-side bridge strut and the reaction-side bridge strut are connected together via a first connecting web at a first end of the brake carrier. Also, the clamping-side bridge strut and the reaction-side bridge strut are connected together via a second connecting web at a second end of the brake carrier. The brake carrier has a brake pad receiving side provided with brake carrier horns, and a brake carrier underside.

摘要： A method (200) for detecting the clearance of a brake (100) of a motor vehicle, in particular a utility motor vehicle, includes the following steps: reading measurement signals of a wear sensor (115) disposed on the brake (100), determining an output signal value that is representative of the non-actuated state of the brake from the measurement signals, determining an event signal value that is representative of the braking state of the brake from the measurement signals, and determining the clearance from the difference between the event signal value and the output signal value, wherein the measurement signals of the wear sensor are examined for the presence of a characteristic signal oscillation that arises as a result of bringing into contact the brake lining with the counterpart thereof that is to be braked. A controller (10) carries out the method on a brake (100).

摘要： A method for performing an evasive maneuver with a commercial vehicle-trailer combination includes ascertaining that a collision between the commercial vehicle-trailer combination and a collision object is impending. The method further includes determining an evasion trajectory by which the commercial vehicle-trailer combination can evade the collision object without coming into contact with the collision object, determining a desired steering angle based on the evasion trajectory and activating an active steering system of the commercial vehicle-trailer combination in dependence on the determined desired steering angle such that the commercial vehicle-trailer combination moves along the evasion trajectory from a starting traffic lane to a target traffic lane so as to perform the evasive maneuver. The method additionally includes determining a desired vehicle deceleration and initiating an electronic braking system of the commercial vehicle-trailer combination in dependence on the desired vehicle deceleration so as to brake the commercial vehicle-trailer combination.

摘要： A discharge cut-off valve for an air compressor is provided. The discharge cut-off valve includes a hinged leaf valve within the recessed portion of a cylinder head manifold. The hinged leaf valve is rotatably anchored at a first end to a joint pin and is guided at a second end by a guide pin. In the on-load phase, the hinged leaf valve is seated over an unloader vent opening while a discharge vent opening is uncovered. In the off-load phase, the hinged leaf valve is seated over the discharge vent opening while the unloader vent opening is uncovered. As a result, compressed air is prevented from escaping the discharge port of the air compressor during the off-load phase, obviating the need for a down-stream turbo cut-off valve in an air dryer, for example.
