A protective cover for a disc is for being disposed on a fork of a bicycle. The fork has a shaft hole. A direction toward which an opening of the shaft hole faces is defined as an axial direction. The bicycle further has a brake disc. The protective cover includes a shell body. As viewed in the axial direction, the shell body and the brake disc are located by the same side of the bicycle, and the brake disc is shielded by the shell body.

A rotor cover is provided that limits contact of a disc brake rotor with an object flying from a radially outer side of the disc brake rotor. The rotor cover covers a disc brake rotor, which is rotatable relative to a bicycle frame. The rotor cover includes a circumferential part that at least partially covers a circumferential edge of the disc brake rotor at a radially outer side of the disc brake rotor. The circumferential part includes at least three first pieces facing the circumferential edge of the disc brake rotor, and first openings provided between two adjacent ones of the first pieces in a circumferential direction of the disc brake rotor.

A rotor cover is provided that includes different portions and is configured to meet requirements of each portion. The rotor cover includes a positioning portion that is positioned relative to a bicycle frame or a disc brake rotor and a cover portion that is coupled to the positioning portion to cover the disc brake rotor. The cover portion and the positioning portion include different materials with respect to one another.

The invention relates to a vehicle brake, in particular a utility vehicle disc brake, having a brake carrier with at least one brake pad holder, at least one brake pad which is guided so as to be axially displaceable and supported in the brake pad holder, and a brake caliper which is axially movable relative to the brake carrier. According to the invention, it is proposed that the brake carrier is structurally reinforced on the run-out side relative to the run-in side, and at least one running direction indicator for indicating the first rotational direction is arranged on the brake carrier.

A caliper cover having a first support member and second support member engaged on a first mount and second mount affixed to opposite sides of a brake caliper. The first and second mounts are held engaged by the fixed spacing of the first and second member. Enhanced engagement is provided through a declining gap formed between opposing first and second portions of the mounts.

A circular segment-shaped filter housing of a brake dust particle filter for a brake disk arrangement has first and second spaced-apart housing side walls. A housing circumferential wall connects the first and second housing sidewalls. The first and second housing side walls and the housing circumferential wall delimit an opening for receiving a brake disk of the brake disk arrangement. Delimitation parts are arranged at an end face edge of at least one of the first and second housing side walls and at an end face edge of the housing circumferential wall. The delimitation parts are detachable and exchangeable independent of the first and second housing side walls and/or of the housing circumferential wall. The delimitation parts delimit a free cross section area of the opening. A brake dust particle filter is provided with such a filter housing. A kit for producing such a filter housing is provided.

The application relates to a brake caliper for a disk brake system comprising a caliper bracket, a caliper housing, a first connecting means and a second connecting means, wherein the first connecting means and the second connecting means may each be configured to mount the caliper bracket to the caliper housing or wherein the first connecting means and the second connecting means may each be configured to mount the caliper bracket to an axle assembly, characterized in that a mass of the first connecting means is different from a mass of the second connecting means.

A brake element is sensorized by at least one piezoceramic sensor arranged between a metallic support element and a block of friction material of a brake element, the sensor being completely embedded within the block. An electrical voltage signal generated by at least one piezoceramic sensor, without the need for a power supply, is picked up by an electrical circuit integrated into the metallic support element. The electrical voltage signal is processed in the form of equal length of samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm. The algorithm is selected from at least one of a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; and integral of the voltage data sample.

A conditioning insert of a friction device includes a body having a conditioning surface configured to engage a wheel, opposite first and second sides intersecting the conditioning surface, and opposite third and fourth sides intersecting the conditioning surface. Each of the first and second sides extend from the third side to the fourth side. The body includes one or more of (a) a recess extending into one or more of the first side, the second side, the third side, or the fourth side and is configured to receive friction material of the friction device and/or (b) a protrusion extending out of the first side, the second side, the third side, or the fourth side and into the friction material of the friction device.

Hybrid or fully electric vehicle comprising: a conventional braking system based on friction bodies to brake the motor vehicle by interaction of the friction bodies in response to the operation of a brake pedal or any other equivalent control member, a reversible electric machine operatively coupled to the wheels of the vehicle and electronically controllable to operate selectively as an electric engine to generate a mechanical power to propel to the vehicle and as an electric generator to convert the kinetic energy of the motor vehicle into electrical energy, and an automotive electronic control system comprising a sensory system to measure automotive quantities, and an electronic control unit to control operation of the conventional braking system and of the electric machine in response to the operation of the brake pedal or any other operationally equivalent control member. The electronic control unit is further configured to control operation of: the electric machine to selectively perform one or more functions including regenerative braking, in which the electric machine is operated as an electric generator to recover the kinetic energy of the motor vehicle during braking and convert it into electrical energy, and the conventional braking system to clean the friction bodies of the conventional braking system based on the number of brakings performed by the conventional braking system and counted starting from the start-up of the motor vehicle.
