Brake part

Disc brake

A lever-operated actuation device for a brake or clutch may have a pump body housing a hydraulic pump provided with a float and a hub rotatably associated with the pump body around a lever pin defining a rotation axis, the hub being associated with a tip operatively connected to the float for its actuation. The pump body may have a pair of fixing ears provided with fixing holes for the lever pin, the lever pin rotatably supporting an associable lever assembly. The lever assembly may have a manual actuation lever and a lever guide suitable to actuate the tip via the hub. The actuation device may have a retention device that keep the hub joined to the pump body, following the removal of the lever pin and the lever assembly for its disassembly/replacement.

Lever-operated improved actuation device for brake or clutch, in particular for motorcycles, and method of disassembly/assembly of a lever-operated actuation device

An actuator device of a braking device and a clutch may have a pump provided with a single operating device for pressurizing a fluid by a float, and a first delivery circuit and a second delivery circuit fluidly connected to an outlet of the pump. The first delivery circuit may be fluidly connectable to a braking device, the second delivery circuit may be fluidly connectable to a clutch. The actuator device may have a diverter device suitable for fluidly connecting the output of the pump alternately with the first delivery circuit and with the second delivery circuit, so as to alternately actuate the braking device or the clutch.

Actuator device of a braking device and a clutch

A braking system for vehicles comprising &#x2014;a manual actuator device, operable by means of a lever and/or pedal, operatively connected to at least a first braking device acting on a brake disc or drum, so as to exercise a braking action, &#x2014;an automatic actuator device, operatively connected to said manual actuator device and/or to said first braking device, &#x2014;at least one command panel which supervises the functioning of the braking system, said command panel being operatively connected to the automatic actuator device and being programmed so that when the manual actuator device is operated, the panel commands the operation of the automatic actuator device so as to be able to: &#x2014;increase the overall braking action of the braking system, further operating the first braking device or further braking devices provided in said system and acting on further brake discs or drums, &#x2014;control the braking action of the braking system so as not to further operate the first braking device or further braking devices of the system, &#x2014;reduce the overall braking action imposed by means of the manual actuator device, directly countering the thrust action exercised on the lever and/or on the pedal.

Automatically controlled braking system

A valve assembly for a braking system having a master cylinder side opening, at least one caliper side opening, and at least one valve pipe, connecting the master cylinder side opening and the caliper side opening. A shutter element has a shutter body movable with respect to the valve body. When the shutter body is in a valve closing position, it interrupts a at least one main fluid passage and defines a master cylinder side pipe stretch facing a master cylinder side opening and a caliper side pipe stretch facing a caliper side opening in the valve pipe. The shutter body at least partially delimits at least one secondary fluid passage, so that, when the shutter body is in a valve closing position, the master cylinder side pipe stretch is in fluid communication with the caliper side pipe stretch only through the secondary fluid passage.

A lever device for hydraulically actuating the brake or clutch of a vehicle equipped with a handlebar may have a pump assembly with a pump body connected to the handlebar of a vehicle. The pump body may have a cavity, a piston operatively associated with the pump body so as to be adapted to slide inside the cavity along a direction of thrust (X-X). The lever device may have a control lever assembly rotatably associated with the pump body so as to rotate about a pivot axis (Y-Y), the control lever assembly may have at least one control level. The piston defines a stroke free play between an end position and a first operating position. The lever device may have a stroke free play adjustment device which is adapted to adjust the distance along the direction of thrust (X-X) between the end position and the first operating position.

Disc brake caliper

A caliper body () for a disc brake unusually capable of high structural performance and low bulk, said caliper body comprising at least one connection bridge () arranged straddling the connection disc of an elongated attachment side portion with an elongated non-attachment side portion; in which said elongated portions have an outer surface () opposite the disc substantially inclined and rounded towards the disc in the radially outward direction so that the caliper body () viewed in the tangential or circumferential direction has a bulk with a rounded outer surface like a tortoise shell.

Caliper body of a disc brake

The invention relates to a braking disc comprising a braking band and a support bell. The band comprises first connecting means and the bell comprises second connecting means adapted to face the first connecting means. The disc further comprises coupling means, each of which is slidingly associated to one of either said first or said second connecting means and is adapted to alternatively take either a fastening position or a release position. When the coupling means are in said fastening position mutually fasten the band and the bell in the axial direction. On the other hand, when the coupling means are in said release position, they allow a mutual movement between the band and the bell in the axial direction.

Bell-band drive connection for disc brake

A lever device for operating a hydraulic actuator for a motorcycle, comprises a support that can be connected to a bearing structure, a hydraulic actuator connected to the support, a main lever, pivotally connected to the support and intended to be operated by being moved close to or away from said hydraulic actuator, a control rod and an adjustment member that are interposed in series between the main lever and a piston of the hydraulic actuator such as to transmit an operating movement from the lever to said piston. The adjustment member pivots about an axis of adjustment and defines a seat that accommodates an end of the control rod. The seat is eccentric to the axis of adjustment, whereby rotation of the adjustment member changes the orientation of the control rod relative to the axis of rotation of the lever, and thus the lever ratio.

Calipers for disc brakes

A device for adjusting the position of the brake lever of a motorcycle comprises a bracket () connectable to a handlebar (), a brake lever () extending in an essentially longitudinal direction (X-X), pivotally mounted on the bracket () and intended to be moved towards or away from a hydraulic actuator (), and an adjustment lever () pivotally mounted on the bracket () and functionally connected to the brake lever () in order to operate the hydraulic actuator () when the brake lever () moves towards the hydraulic actuator (). The device () possesses means () for adjusting the position of the brake lever () with respect to the adjustment lever (), these means comprising a pin () extending in the longitudinal direction (X-X) in a continuation of the brake lever (), which pin is engaged in such a way that it can be adjusted axially with respect to the brake lever () and is engaged in abutment with the adjustment lever (), so that a movement in the longitudinal direction (X-X) of the pin () with respect to the brake lever () corresponds to a change in the position of the brake lever () with respect to the adjustment lever ().
