A joystick control is disclosed for a change speed gearbox having a support body, an axle rotatably supported by the body, an operating lever connected to the axle by a pivot pin having an axis perpendicular to that of the axle such that the operating lever is rotatable about the axis of the axle and is pivotable relative to the axle about the axis of the pivot pin, two actuating members rotatably supported by the axle and arranged one on each side of the operating lever, each actuating member being connectible to a respective Bowden cable to extend and retract the cable in response to rotation of the actuating member about the axle, and mating formations on the operating lever and the actuating members operative to engage the operating lever selectively for rotation with one or the other of the actuating members in dependence upon the direction in which the operating lever is pivoted relative to the axle about the pivot pin. Resiliently biased detents are provided between the support body and the actuating members or the operating lever to resist rotation of the operating lever away from at least one defined stable position.

A control device for a crawler vehicle comprises a control lever activated by an operator about a fulcrum and having a free end, the control lever being displaceable along a longitudinal direction of the vehicle between a proximal position closer to the operator and a distal position further from the operator in order to control a main clutch of the vehicle, the control device further comprising a support element suitable for being fixed to a body of the vehicle in order to support an operator's hand when the hand acts on the control lever, the control lever having an intermediate portion interposed between the free end and the fulcrum, the intermediate portion being so shaped as to partially embrace the support element in the proximal position.

A vehicle control device, in particular a clutch mechanism for a tractor, includes a control lever and guide mechanism in which the lever is selectively movable from a first rest position to a second engaged position. The control lever is subjected to the action of an elastic apparatus operable to move the lever into the first rest position if the lever is released before reaching a given point along the guide mechanism. The elastic apparatus also being operable to move the control lever into the second engaged position if the control lever is released past the given point.

A transmission is described for a motor vehicle having selectable four-wheel drive. The transmission includes a coupling for selectively applying torque to the front wheels of the vehicle to switch between two-wheel drive and four-wheels drive in dependence upon slipping of the driven wheels. The coupling includes a drive member rotatable with the rear wheels, a driven member rotatable with the front wheels, the drive and driven members being movable axially relative to one another. The drive and driven member have teeth which mesh with one another in a first relative axial position of the drive and driven members to transmit torque from the drive to the driven member, but which are disengaged from one another in a second relative axial position of the drive and driven members to disconnect the drive to the front wheels. Slipping of the rear wheels is sensed electronically and is used to move the drive and driven members axially between the first and second relative positions in dependence upon the determined presence or absence of slipping of the driven wheels.
