  • Patent number: 7484601
    Abstract: 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.

  • Publication number: 20080296102
    Abstract: 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.

  • Publication number: 20080283347
    Abstract: 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.

  • Publication number: 20080217121
    Abstract: The invention relates to an electromechanical disk brake which has a switchable freewheel in order to be configured as a parking brake. The switchable freewheel includes a clamping roller freewheel having rollers for locking a motor shaft of an electric motor of the brake. A locating bearing of the motor shaft of an electric motor, and the freewheel are accommodated on a cover of a housing of the electric motor, and all the electric connections of the disc brake are routed via the cover. The number of components used can be reduced considerably by the integrated design. Moreover, the positional tolerances of the freewheel in relation to the motor shaft can be reduced with the aid of the invention.

  • Publication number: 20080190717
    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.

  • Publication number: 20080185240
    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.

  • Patent number: 7398866
    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).

  • Publication number: 20080164105
    Abstract: An electromechanical disk brake having a self-boosting by means of a ramp mechanism with an encapsulation to protect moving parts of the brake against becoming soiled. The friction brake lining has a three-point support with three roller bodies and thus is braced in a statically defined way, and a contate gear mechanism for actuating the disk brake, which is not vulnerable to positional tolerances and does not cause any axial forces.

  • Patent number: 7364021
    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.

  • Publication number: 20080011559
    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.

  • Publication number: 20070151815
    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.

  • Publication number: 20070137949
    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.
