Abstract
A lever device for operating a hydraulic actuator for a motorcycle comprises a support, a hydraulic actuator connected to the support, a main lever pivotally connected to the support for movement toward or away from the hydraulic actuator, and a timing lever pivotally connected to the support and connected to the main lever so as to operate the hydraulic actuator. An adjusting member is interposed between the main lever and the timing lever defines the relative position between the levers. An electric actuator changes the position of the adjusting member as a function of an electric power supplied to the actuator from a manually adjustable power supply.
Claims17
A lever device for operating a hydraulic actuator on a motorcycle, said device comprising:
- a support to 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 towards or away from said hydraulic actuator,
- an adjusting member disposed between the main lever and the support, for adjusting the position of the main lever relative to the support,
- an electric actuator, comprising an electric motor, for changing the position of the adjusting member,
- a power supply for the electric actuator,
- a manual operating member interacting with the power supply so as to operate the electric actuator, and
- means for compensating for misalignment between the adjusting member and the electric actuator,
- wherein said motor has a drive shaft which is coaxial with the adjusting member and is connected to the adjusting member by a bush, said bush having a first seat that provides a rotary coupling with said drive shaft and a second seat that provides a rotary coupling with said adjusting member, wherein one of the first and second seats forms a longitudinal guide for the drive shaft or adjusting member such as to compensate for longitudinal displacements of the adjusting member relative to the drive shaft.
