摘要:
A self-boosting, electromechanical friction brake having with a fixed, drumlike brake body in which two rotatable brake rings are disposed, which are rotatable counter to one another via a planetary gear and can be spread apart thereby. As a result of being spread apart, the brake rings are pressed from inside against the brake body and are braked. The friction brake may be sealed off and thus protected it against environmental factors. A lubricant filling is possible, which reduces wear and as a result makes a lifetime brake possible. The brake may be cooled through coolant channels which can be connected via connections to a coolant circulation system of an internal combustion engine of a motor vehicle.

The invention relates to a self-boosting electromechanical disk brake with a frame caliper equipped with a wear readjustment device which for instance is automatic and which upon tensing of the disk brake stores energy by prestressing a torsion shaft, which upon release of the disk brake converts this energy into a wear readjustment motion. In the process, a spacing between two brake lining holders of the frame caliper in the disk brake is decreased.

The invention relates to a self-reinforcing electromechanical disc brake having a brake caliper produced by means of shaping, in one piece with a housing for electromechanical parts of an actuating device of the disc brake, with the housing forming a dimensionally stable hollow body. It is possible in this way to produce a bending-resistant and torsionally rigid brake caliper with a low wall thickness.

The invention relates to a selective freewheeling mechanism for developing an electromechanical vehicle brake (service brake) into a parking brake. The freewheeling mechanism according to the invention has an outer ring and a locking element cage which are configured as an electric motor with a rotor and a stator. The rotor and stator can be swiveled in relation to each other when a coil is supplied with current. Due to a symmetric design, the freewheeling mechanism is advantageously insensitive to acceleration forces.

A method and device for monitoring a distributed system made up of a plurality of users that are connected by one bus system are provided, in which distributed system at least a number of the users are provided as monitoring users. The process data of at least one monitored user are filed in data areas of memory units of the bus system, to which the monitoring users have access, and the process data are evaluated by the monitoring users.

The present invention relates to a self-amplifying electromechanical partial lining disc brake, having a ramp mechanism as a self-amplification device. According to the invention, a rack for driving a friction brake pad is situated between roller elements of the ramp mechanism, particularly at a geometrical centroid of an imaginary surface defined by the roller elements. As a result a load is distributed to the roller elements in a more uniform fashion and the pressing force of the friction brake pad against a brake disc when the partial lining disc brake is actuated is distributed more uniformly and counteracts irregular pad wear.

The invention relates to a self-energizing electromechanical friction brake includes a self-energizing device provided with, for example, a wedge mechanism. According to the invention, the friction brake is equipped with a linear drive, for example an electromagnet, for brake actuation. The self-energizing device converts a friction force exerted by a rotating brake body on a friction brake lining during braking actuated by the linear drive of an actuation device into a second contact pressure that presses the friction brake lining against the brake body in addition to the first contact pressure exerted by the actuation device. The self-energizing device provides a non-proportional characteristic magnetic force curve of the electromagnet of the linear drive.

A self-boosting electromechanical friction brake, having a friction brake lining which is displaceable for actuation in the direction of rotation of a brake disk and which is braced via roller bodies on ramps of an abutment plate. When the brake is actuated, brake disk exerts a frictional force on the brake lining pressed against it, which urges the lining in the direction of an increasingly narrow gap between the ramps and the brake disk to exert a contact pressure that is in addition to that exerted by an actuation device to attain self-boosting. The roller bodies are supported fixedly and rotatably in bearing block on the brake lining whereby the roller bodies move in slaved fashion with the brake lining and always brace the brake lining at the same points.

The invention relates to a friction brake lining having a lining holder for a disk brake in which the lining holder includes an encompassing rim and/or beads, which form a kind of reinforcing ribs and reinforce the lining holder against bending. The invention makes a thin and hence lightweight lining holder possible, which can be manufactured by deep drawings.
摘要:
The invention relates to an electromechanical friction brake, for example in the form of a disc brake having an electromechanical actuation device. The electric motor of the actuation device presses a frictional brake lining against a brake disc by means of a reduction gearbox and a ball ramp mechanism. The actuation device is supported by a spring washer that is pretensioned so strongly that when the disc brake is released it acts on a segment with a falling spring characteristic; that is, a spring force exerted by the spring washer on the frictional brake lining increases with increasing tension of the disc brake.
