<p>A transmission selector mechanism is provided with a cross shaft (18) operating in a substantially perpendicular axis to a selector shaft (22). The cross shaft has three striking fingers (20,38,40) mounted on it, a first striking finger (20) is secured to the cross shaft and co-operatively engages a selector block (34) mounted on the selector shaft; axial motion of the cross shaft thereby generates a radial motion of the selector block about the selector shaft axis, a second striking finger (40) is selectively engagable by means of the axial motion of the cross shaft, and when engaged upon the cross shaft by engagement means (44) rotation of the cross shaft and engaged striking finger moves the selector block in an axial direction along the selector shaft; a third striking finger (38) is selectively engaged when the second (40) is disengaged and upon rotation of the cross shaft acts on the selector block through a reverse acting toggle mechanism (52,54,56) to move the selector block axially along the selector shaft, the axial movement of the selector block thereby selecting the chosen gear ratio. <IMAGE></p> |
