Control of the joystick for a gear box of the change of speed and worm gear box connected by two Bowden cables to a joystick control

摘要

Summary "joystick control for a gear box of the change of speed and worm gear box connected by two Bowden cables to a control of a control joystick" joystick is disclosed for a gear box of the change of speed, which comprises a body support (11 2), a shaft (118) sustained way rotary body (112),An operating lever (124) connected to the shaft (118) by a pivot pin (126) which has an axis perpendicular to the geometric axis (118) so that the operating lever (124) is swinging around the centre line of the axle (118) and is pivotable relative to the axis (18) around the hey XO geometric pivot pin (126).Two states of actuation (130) supported by the axle rotating way (118) and arranged each on one side of the operating lever (124), each state of operation (130) is connectable to a respective Bowden cable (44) to extend and retract the cable (44) in response to the rotation of the state of Performance (124) around the axis (118), and a coupling (124a,150) training in the operating lever (124) and the states of actuation (130) operating to pick up the operating lever (124) selectively for rotation with one or the other of the states of actuation (130) in dependence upon the direction in which the operating lever ( 130) is pivoted relative to the axis (18) around the pivot pin (126).In the invention, polarized resilientemente retainers (160170) are provided between the body support (112) and the states of actuation (130) or the operating lever (124) to resist rotation of the operating lever (124) out of at least one stable position defined.
