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.

Actuator device for a hydraulic actuation system of a brake/clutch of a motorcycle, with separate adjustment of the distance and pitch of the actuation lever

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.

Actuating device with collapsible lever

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

Setting screw for a control lever device

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.
