The present invention provides a disk brake system comprising a wheel defining a rotational axis, a caliper mounted adjacent the wheel, and a rotor mounted for rotation with the wheel and engageable by the caliper. The rotor includes a mounting slot defined by first and second sidewalls, the first sidewall defining a first axis that substantially intersects the rotational axis, and the second sidewall defining a second axis that is substantially parallel to the first axis. Preferably, the mounting slot defines a center axis that intersects a radial axis of the wheel at an angle of at least 1.5 degrees, preferably at least 2.0 degrees and more preferably about 2.5 to 3.9 degrees. Preferably, the mounting slot has a width and a length that is at least 10% larger, preferably at least 15% larger, and more preferably about 20% larger than the width.

The invention relates to a method for controlling a braking system of a vehicle for distributing braking forces on at least one piston of a disc brake caliper of the vehicle. The method is performed by a braking system control system. The method comprises the steps of: receiving, by the control system, a request for applying a braking force following a braking action applied on a pedal/button of the braking system; applying the required braking force to the at least one piston; detecting a current characteristic frequency information of the braking system by means of at least one sensor operationally associated with the braking system, this characteristic frequency is representative of current noises and/or vibrations associated with the braking system; comparing this detected current characteristic frequency information with a reference characteristic frequency representative of a critical operating condition of the braking system;
if the detected current characteristic frequency information of the braking system is equal to the reference characteristic frequency, the method further comprises the step of: applying to the at least one piston of a disc brake caliper of the vehicle an additional braking force generated by superimposing a force signal having a time-variable amplitude on said requested braking force.

A brake disk for a motor vehicle includes a friction ring and at least one insert portion. The insert portion is located within and arranged coaxially with the friction ring, and is configured so as to possess an annular disk shape and define a plurality of openings. The friction ring is configured such that material of the friction ring fills the plurality of openings.

A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

Anti-squeal shim (100) comprising a fiber reinforced vibration insulating layer (110) and a vibration absorbing layer (120), the fiber reinforced vibration insulating layer comprises reinforcement fibers, a filler material and a binder material. There is also provided a method of producing anti-squeal shims, and a method of preventing squeal noise from a disc brake.

A vibration damping device having improved air-tightness of a chamber holding a rolling mass in an oscillatable manner is provided. A cover member that covers an oscillating range of the rolling mass liquid-tightly or air-tightly comprises a first flange and a second flange. The first flange is pushed onto one of lateral faces of a holding member by a first pushing member fitted onto a rotary member while being prevented to move axially to seal a clearance between the holding member and the first flange by a first sealing member. The second flange is pushed onto the other lateral face of the holding member by a second pushing member fitted onto the rotary member while being prevented to move axially to seal a clearance between the holding member and the second flange by a second sealing member.

One embodiment includes a damped product including a first portion, a second portion, a first cavity formed in one of the first portion or the second portion, and a frictional damping insert at least partially received in the first cavity so that the first portion and the second portion completely enclose the frictional damping insert and so that vibration of the product is damped by the insert.

A rotary drive reduction gear within an electric brake actuator includes one or more planetary gear sets parallel or coaxial to a linear actuation direction, which are provided with at least one rotationally fixed ring gear. The reduction gear has an elastomeric damping device, which is arranged around the fixed ring gear and compressed radially and/or axially between the fixed ring gear and a brake housing. The reduction gear is a differential planetary gearset driven by a sun gear with planet gears meshing simultaneously with the fixed ring gear and a movable ring gear. The latter drives the nut of a reversible screw-nut mechanism, which produces a linear force. The overall irreversibility is produced by the differential gearset. Also provided is a component determined for producing the damper of this reduction gear, to a motor unit including this damper, to a brake and to a method for assembling same.
