Abstract: A lever assembly for a lever device having a master cylinder body having cylinder walls delimiting a cavity or cylinder, and a float or piston having a piston bottom defining a pressure chamber. A supply channel puts the pressure chamber in communication with a fluid tank. The piston bottom is movable between an end-of-stroke position, in which a volume of the pressure chamber is maximum, and a first working position, in which the piston bottom fluidly isolates the pressure chamber from the supply channel. The lever has a primary lever connectable to the float or piston and an elastic return element having a first elastic return element winding, a first arm, and a second arm. A primary lever body defines a primary lever recessed housing or seat to accommodate the elastic return element and has a first primary lever connecting element having a coupling portion to couple the second arm.

Abstract: A lever device has a master cylinder body having cylinder walls delimiting a cavity or cylinder, a float or piston and a lever assembly having a primary lever having a primary lever thrust portion, a secondary lever or hub connected to the float or piston and having a secondary lever counter-abutment portion. The primary lever rotates between a primary lever resting position, and at least one primary lever actuation position. The lever assembly has an elastic return element configured to elastically bias the primary lever to the primary lever resting position. The secondary lever or hub is operatively connectable to a combined braking mechanism actuatable by a combined action lever. An elastic relative-load element connected to the primary lever and/or the secondary lever or hub applies an elastic spacing action which opposes an approach of the secondary lever counter-abutment portion to the primary lever thrust portion. or vice versa.

Abstract: The actuator device for a hydraulic actuation system for a brake/clutch for a motorcycle is described. The actuator device may have a support structure associable with a handlebar of the motorcycle. The actuator device may also have an actuation assembly having a push rod operatively connectable to at least one braking device. The actuator device may also have an actuation lever connected to the support structure so as to be rotatable about an actuation axis, where the actuation lever is provided with a pusher adapted to interface with the push rod. The actuator device may also have an adjustment device adapted to modify both the angular position, in a rest condition, of the pusher and of the actuation lever with respect to the handlebar and to modify a pitch between the actuation axis of the actuation lever and a contact and thrust point of the pusher on the push rod.

Abstract: A brake or clutch actuating lever is rotatably connected to a support structure. An adjustment lever, mechanically distinct from the actuating lever, transmits the angular actuation stroke of the actuating lever to a brake or clutch actuation unit. The adjustment lever comprises a mechanism for adjusting the rest position of the adjustment lever, mechanically separate from the actuating lever.

Abstract: An adjusting screw (15) for a control lever device (1) for vehicles, wherein said adjusting screw (15) comprises a screw body (18) with a threaded shank (19) that can be screwed in a corresponding threaded hole (16) of the lever device (1) and a locking body (26) pivotally connected to the screw body (18). The locking body (26) comprises contact means (27) interacting with the screw body (28, 18) such as to counteract the rotation of the locking body (26) relative to the screw body (18) to a certain extent and anchoring means (29) engaging an anchoring seat (17) of the lever device (1) such as to prevent that the locking body (26) may rotate relative to the threaded hole (16) of the lever device (1). There are also provided means (25) for preventing that the locking body (26) may be displaced along the shank (19) of the screw body (18).

Abstract: A control device such as a handlebar-mounted brake includes a support structure containing a hydraulic piston, a lever pivotally connected to the support structure by a pin, and a transmission element for transmitting force from the lever to the piston during a normal actuation stroke of the lever. The lever may pivot outward substantially beyond its normal rest position. A torsion spring biases the lever in the actuation direction so that the lever and the transmission element are normally in contact. However, in the event of a fall, the lever can pivot outward from its normal rest position, out of contact with the transmission element. The hydraulic components are thereby protected from damage, as the pin and support structure bear the entire impact force applied to the lever.

Abstract: An actuating device with lever for vehicles, comprising a support structure, an actuation unit, an actuating lever connected rotatably to the support structure and an adjustment lever, mechanically distinct from the actuating lever and set in such a way as to transmit the angular actuation stroke of the actuating lever to the actuation unit in order to actuate the latter. The adjustment lever comprises adjustment means suitable for adjusting the rest position of the adjustment lever; the said adjustment means are mechanically separate from the actuating lever. The actuating lever comprises elastic preload means suitable for elastically influencing the actuating lever in abutment against the adjustment lever.
