Abstract: A spreader unit for a drum brake is provided with a readjustment device which ensures that the clearance remains substantially constant even in the case of wear on the brake linings. The readjustment device is arranged between actuating pistons and changes the spacing of the actuating pistons in at least one readjustment step when an actuating travel of the first and second brake shoe holders has exceeded a travel setpoint value. A thermally actuable blocking device mechanically prevents the execution of the readjustment step by the readjustment device at a temperature above a temperature setpoint value.

Abstract: For controlling electromechanically actuatable brakes of servo type construction, it is necessary to detect the forces acting on the abutment of the brake shoes. The abutment is therefore formed from a massive material which deforms under load, wherein measurement devices are provided which detect this deformation. The shape of the abutment is selected in such a way that the abutment has measurement gaps, the size of which changes when the abutment is loaded. The size of the measurement gaps can be sensed by means of Hall sensors or AMR sensors, for example.

Abstract: A method for ascertaining operating variables of a drum brake has the following steps: a) recording at least one supporting force of a brake shoe of the drum brake by means of a sensor, and b) ascertaining the operating variable based on the supporting force, the operating variable being selected from the brake lining friction value and the spreading force.

Abstract: A drum brake having a brake drum, brake shoes, a carrier plate and a load measurement device in the region of an abutment is mountable on a steering knuckle. The abutment has a cylinder in which two pistons are guided, on the outer end faces of which the abutment ends of the brake shoes rest and the inner end faces of which are each supported by a spring on a step in the cylinder. A hollow peg projects from the outside of the cylinder and penetrates an opening in the carrier plate, such that it can be received in a receiving space in the steering knuckle resting on the carrier plate or in a reinforcement element fixed on the steering knuckle.

Abstract: A brake device for a motor vehicle has an actuator with a common housing for a spreading actuator, and an adjusting device. An electric motor for actuating the actuator can be driven in two rotational directions, the spreading actuator being driven in the one rotational direction, and the adjusting device being driven in the other rotational direction.

Abstract: A drum brake for an electrical motor vehicle brake system wherein actuator means, a transmission means and a spreading device are in a force flow with movably mounted drum brake shoes that are suitable and designed to cooperate with a brake drum. The force flow, in a electromechanically actuatable drum brake such that closed-loop electrical brake control in conjunction with simple actuator control is made possible with reduced outlay over the entire wearing service life of the brake shoe. Transverse offset compensation is provided by way of, a joint-disk-type/joint-socket-type bearing geometry such that a friction lining bearing support geometry with profiling allowing mutual articulation such that transversely oriented lining displacement with respect to the a direction is at least reduced.

Abstract: A method for ascertaining an operating variable of a drum brake, the method using forces acting on supporting bearings. The invention further relates to an associated drum brake assembly, an associated analysis unit and an associated storage medium.
