Abstract: The invention relates to a self-boosting electromechanical friction brakes particularly in the form of a partially lined disk brake. The friction brake includes a friction brake lining which is helically movable with respect to the direction of rotation of a brake disk and pressed there into. A ramp mechanism is provided with ramps which cooperate with a roller bearing mechanism supporting the brake lining, to obtain the self-boosting effect. According to the invention, two of three rolls of the ramp mechanism are embodied with directing flanges for guiding the rolls on the ramps in order to helically guide the friction brake lining.

Abstract: A self-boosting electromagnetic disk brake having an electromechanical actuating device and a mechanical self-boosting device that has a wedge mechanism. A wedge is displaceable parallel to a brake disk and relative to a friction brake lining, and the relative displaceability of the wedge is limited relative to the friction brake lining to one direction, by means of a slaving device. The wedge is decoupled from the friction brake lining in one direction of rotation of the brake disk. As a result, the self-boosting device is operative in only one direction of rotation of the brake disk; in the reverse direction of rotation of the brake disk, the disk brake is neutral in terms of self-help.

Abstract: The invention relates to a self-reinforcing electromechanical disk brake. The invention proposes to produce a lining carrier plate of the disk brake from a fiber composite material. A bending-resistant lining carrier plate can be produced cost-effectively in this way. In addition to fiber-reinforced plastic, steel-reinforced concrete can also be considered as a composite material for the lining carrier plate.

Abstract: The invention relates to an electromechanical, self-boosting friction brake, in particular a disk brake. The friction brake is embodied with a wedge element for exerting contact pressure on a friction brake lining; a wedge angle (?) is selected such that a brake parameter C* is located at or near a pole point. As a result, a high self-boosting that tends toward infinity and consequently a low actuating force are attained. To avoid blocking of the friction brake, an actuating device is embodied to block an independent motion of the wedge element, or has a regulating device for regulating a contact pressure of the friction brake lining against a brake body (brake disk).

Abstract: The invention relates to a wheel brake for a motor vehicle including an electromechanical actuating device and a hydraulic actuating device, which are redundant. In this way, the likelihood of failure of the wheel brake is reduced. A self-boosting device increases a braking force of the wheel brake, so that an (underpressure) brake booster can be dispensed with. Wheel slip control is possible in a simple way by hydraulic actuation of the wheel brake and superposition of a braking force regulation on the electromechanical actuating device. The wheel brake includes a support member on the side of a friction brake lining opposite a brake body. The support member has two wedge inclines and a flattened middle portion on a side opposite the friction brake lining. The pressure fluid actuating device has a tappet resting on the flattened middle portion.

Abstract: A self-boosting electromechanical friction brake for a motor vehicle in which, with an electromechanical actuator, a friction brake lining can be pressed against a brake disk, and the friction brake lining is braced in the brake caliper via a wedge mechanism, which effects a self boosting. A friction brake lining which is pressed by the actuator has with a lower coefficient of friction, and in particular with less relative fluctuation in the coefficient of friction, than another friction brake lining positioned fixedly in the brake caliper. An operation-dictated fluctuation in the coefficient of friction and thus a change in the self boosting is reduced, and as a result the disk brake, with a low coefficient of friction, can be actuated with less actuation force and less actuation energy.

Abstract: The invention relates to 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 is braced on a ramp, via a roller body. When the friction brake is actuated, a rotating brake disk exerts a frictional force on the friction brake lining pressed against it, which urges the friction brake lining in the direction of an increasingly narrower gap between the ramp and the brake disk and as a result exerts a contact pressure in addition to a contact pressure exerted by an actuation device. The self-boosting action is attained as a result. To prevent the roller body from sliding on the ramp, the invention provides a positive controller, for instance with a gear wheel on the roller body that meshes with racks.

Abstract: 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.

In this way, a support angle (?) and thus a magnitude of the self-boosting of the disk brake can be varied.
