<p>Remote control linkage for a gearbox of a motor vehicle includes a pair of driven levers, one for selecting the gear ratios and the other for actually producing the shifting to the selected gear ratio. The levers are operatively connected to a gear shift lever operable by the driver through linkage including a pair of links pivotally connected to the driven levers and a main control rod extending across the links. One link connects one of the driven levers to one arm of a control member consisting of a two-armed bell-crank lever fulcrumed at the junction of its two arms to a pivot pin rigid with the body of the vehicle. The main control rod is pivotally connected at three points, that is, to the other link connected to the other driven lever, to the end of the other arm of the two-armed control member, and to the gear shift lever. The pivotal connections between the main control rod and the other link and the other arm of the bell-crank lever consist of universal ball-and-socket joints. The center of the pivotal connection between the main control rod and the gear shift lever is located at the end of the gear shift lever on an axis extending across the main rod.</p> |
