Abstract
An arrangement for damping a possible pitching oscillation of a working vehicle supported on the ground by elastic elements is equipped with means to detect an expected and/or existing pitching oscillation of the working vehicle, and a control device, which is connected to the means and to an actuator to influence the propulsion rate of the working vehicle and which can be operated to control the actuator so as to damp the pitching oscillation.
Claims6
An arrangement for dampening a pitching oscillation of a working vehicle supported on the ground by elastic elements, said arrangement comprising:
- at least one sensor for detecting at least one of:
- an expected pitching oscillation of the working vehicle, the at least one sensor coupled to at least one of a speed control of the working vehicle, a ground profile determination device or a control device for adjusting the elastic elements relative to the working vehicle, or
- an existing pitching oscillation of the working vehicle;
- and
- an actuator for influencing the propulsion rate of the working vehicle;
- and
- a control device connected to the at least one sensor and the actuator to control dampening of the pitching oscillation, wherein the control device comprises a signal shaper, operable to transmit a received speed specification signal to the actuator and to issue, in a time-delayed manner, a second speed specification signal to the actuator.
