Abstract
Steering equipment for a work vehicle includes a steering transmission shaft mounted so that the shaft can turn within a steering column, and with a control device for actuating a steering operating unit. The control device includes a reference member, which can move along the transmission shaft and a sensor device fixed to the steering column in a position substantially facing the reference member for detecting a position of the reference member along the transmission shaft. The sensor provides a displacement signal that is used to vary the steering ratio, such as steering speed.

Steering equipment for a work vehicle comprising:
- a steering unit including a steering column having a first longitudinal axis, a steering transmission shaft mounted inside the steering column for rotating about said first axis, a steering wheel mounted on the transmission shaft and a control device for actuating a steering operating unit, the control device further comprising:
- a reference member disposed on the steering unit to move along said first longitudinal axis;
- actuator means for displacing the reference member along the first axis;
- and
- sensor means for detecting a position of the reference member along the first longitudinal axis, wherein the sensor means is mounted on the steering column in a position substantially facing said reference member.
In a work vehicle having a steering unit including a steering column having a first longitudinal axis, a steering transmission shaft mounted inside the steering column for rotating about said first axis, a steering wheel mounted on the transmission shaft, and a control device for actuating a steering operating unit, the control device comprising:
- a reference member disposed on the steering unit and movable along said first longitudinal axis;
- actuator means for displacing the reference member along the first longitudinal axis;
- a sensor for detecting a position of the reference member along the first longitudinal axis;
- and
- the actuator means further comprising an actuating member having a second longitudinal axis, the actuating member being operable to move between a resting position, in which the actuating member and reference member are substantially coaxial with respect to one another, and an operative position, in which the first and second longitudinal axis form an angle other than zero with respect to one another.
Steering equipment for a work vehicle comprising:
- a steering unit including a steering column having a first longitudinal axis, a steering transmission shaft mounted inside the steering column for rotating about said first axis, and a steering wheel mounted on the transmission shaft for controlling the steering of at least one wheel of the vehicle;
- hydraulic means disposed between the steering unit and the vehicle wheel;
- a control device acting on said hydraulic means for varying a ratio between an angle of rotation of the steering wheel about the first axis and an angle of steering of the wheel;
- and
- the control device further comprising:
- a reference member disposed on the steering unit and movable along said first axis;
- an actuator mechanism for moving the reference member along the first axis;
- and
- sensor means for detecting a position of the reference member along the first axis, said sensor means being mechanically disconnected from said reference member.
