Title:
SERVO ASSISTED ACTUATING SYSTEM FOR A MULTISPEED GEARBOX OF A VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/031612
Kind Code:
A3
Abstract:
The invention relates servo assisted actuating system for a multispeed gearbox, comprising a servo cylinder, a cable (1) adapted to be connected to a lever at one end portion and to be connected to an actuating component by a coupling mechanism at its other end portion to transmit cable movements to actuating movements of the actuating arm, and a control valve controlled by the actuating component to selectively supply pressurized fluid to the servo. According to the invention the actuating component is an actuating arm (2) which extends from an inner chamber of the servo cylinder to the outside thereof, wherein the actuating arm has disposed along its length a bearing portion (2') that is disposed in a bearing and wherein bearing position and bearing are adapted to allow actuating movements of the actuating arm, and to allow movements of the actuating arm (2) along its longitudinal direction between an operative position in which the actuating arm is operable to control the control valve by actuating movements, and a shifted release position; wherein the coupling mechanism comprises two coupling members (3, 6) which are disposed within the inner chamber and moveable relative to each other between an open position and an engaged position in which the coupling members (3, 6) are able to engage and hold an end portion of the cable disposed therebetween; wherein the coupling mechanism and the actuating arm are arranged to cooperate such that movement of the actuating arm (2) from its release position to its operative position brings the coupling members (3, 6) from the open position to the engaged position on the end portion of the cable (1).
