A system for the supplemental generation of energy from the operation of a vehicle operation, and specifically to the generation of energy in connection with a vehicle's drum brakes in combination with brushless electric motor-generators. The system includes a rotational conveyor that operatively connects the drum to a coupler member attached to a generator so that rotation of the drum rotates the coupler member to create energy. A frame member may position and retain the generator in place relative to the drum.

An anti-lock sensor ring may have a flattened exciting portion having a retention mechanism projecting from a ring radial edge. The retention mechanism may have cantilever spring retention clips elastically deformable to snap on a disc brake band retention seat. The mechanism may also have a cantilever support portion disposed side by side to and spaced apart from the cantilever spring retention clips. Each of the cantilever spring retention clips may have a retention surface and the cantilever support portion with a support surface. When the anti-lock sensor ring is dismounted from a disc brake band, the plane defined by the retention surface and the plane defined by the support surface are facing each other in order to create opposing gripping elements.

A wheel hub is configured to rotate about an axis of rotation during operation, and includes a brake disk abutment surface against which a brake disk bears in an installed state, and a wheel-hub-side contact surface which is offset in an axial direction with respect to the brake disk abutment surface and which runs obliquely with respect to the axis of rotation and against which at least a part of a fastening assembly, by which the brake disk is fastenable or fastened to the wheel hub, bears in the installed state.

A brake disc for a bicycle comprising a first component made of a first material and having a braking track configured to cooperate with brake pads. A second component is made of a second material and having (i) a radially inner annular portion for coupling with a hub of a bicycle wheel and (ii) a plurality of radially outer portions for connecting to said first component at a respective plurality of connection portions of said first component. The first component further comprises a radially inner annular portion connected to said braking track, and the brake disc comprises axial locking members active on the radially inner annular portions of the first and of the second component to keep said radially inner annular portions of the first (30) and of the second component under mutual pressure.

A brake disc having a first component made of a first material, a braking track configured to cooperate with brake pads, and a second component made of a second material and having (i) a radially inner annular portion for coupling with a hub of a bicycle wheel and (ii) a plurality of radially outer portions for connecting to said first component at a respective plurality of connection portions of said first component. The first component comprises a plurality of connection arms that extend from said braking track towards said predetermined rotation axis (X) and that are distinct from said plurality of connection portions, wherein at least one of said connection arms of said first component and at least one of said radially outer connection portions of said second component are coupled together through at least one shape coupling.

A braking band having an annular band body arranged around a rotation axis and made of one of gray cast iron, steel, aluminum or alloys thereof, has at least one braking surface having an activated band body portion for increasing adhesive capacity of at least one protective surface coating placed on the surface of the activated band body portion and having at least one material with elevated resistance to abrasion. The activated band body portion is arranged on the surface of the annular band body to form an outermost layer of the braking band with the at least one protective surface coating and has a rough profile having at least one channel delimited by at least one pair of projections, extending along a path at least partially surrounding the rotation axis and having a channel bottom and a first channel side forming an acute angle with the channel bottom and an opposite second channel side forming an obtuse angle with the channel bottom.

An adapter of a brake system includes a body that extends around a portion of an axle of a vehicle system. The body may include an interior portion that is positioned between a center passage of the body and an exterior portion of the body in a radial direction away from the center passage. A hub coupling feature is positioned on the interior portion of the body and may be coupled with a portion of a wheel hub of the vehicle system. A brake disc coupling feature is positioned on the exterior portion of the body and may be coupled with a portion of a brake disc assembly. The wheel hub and the brake disc assembly are incompatible such that the wheel hub is prohibited from being directly coupled with the brake disc assembly.

A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

A power tool comprises a motor, a final output shaft, a tool body, a detection device, and a braking device. The motor has a motor body including a stator and a rotor, and a motor shaft extending from the rotor and being rotatable around a first rotational axis. The final output shaft is configured to be rotationally driven around a second rotational axis by torque transmitted from the motor shaft. The tool body houses the motor and the final output shaft. The detection device is configured to detect a locking state of the final output shaft. The braking device is configured to directly act on the motor shaft to brake the motor shaft in response to detection of the locking state.

A brake rotor, includes at least one friction element and one adapter element, wherein the brake rotor is configured to rotate about an axis of rotation, wherein the friction element has at least one friction surface and one connection region, wherein the adapter element has an installation region and a transfer region, wherein the installation region is configured for fixing the brake rotor to a hub, wherein the connection region indirectly or directly engages in positively locking fashion in a circumferential direction with the transfer region such that a torque about the axis of rotation can be transferred between the connection region and the transfer region from the friction element to the adapter element.
