Abstract
A friction mechanism coupled to a drive system for mounting in a housing of a counterbalance mechanism for a closure panel of a vehicle, including: a shaft having an axis; a friction member positioned on the axis; a pinion with a friction body positioned on the shaft and adjacent to the friction member, the pinion rotatable about the axis relative to the friction member during rotation of the shaft to generate friction between the friction member and the friction body; a pusher body positioned on the axis; an actuator of the drive system connected to the pusher body in order to affect an axial position of the pusher body on the axis; and a resilient element positioned on the axis between the pusher body and the friction member, such that the resilient element exerts an axial force on the friction member to force the friction member against the friction body; wherein operation of the actuator causes a change in the axial position of the pusher body on the axis and thus a degree of compression of the resilient element positioned between the pusher body and the friction member.
