<p>PURPOSE:To perform bodily sensation of an acceleration deceleration feeling responding to the demand of a driver, in an industrial vehicle having a radial cylinder type variable displacement pump/motor. CONSTITUTION:The driving shaft 3a of a hydraulic pump 3 for running is caused to effect drive-coupling with the output shaft of an engine 1. The output shaft 4a of a hydraulic motor 4 is coupled with a drive wheel 7 through a driving shaft 5 and an actuating gear mechanism 6. During acceleration running, the driving speeds of step motors 29A and 29B are set based on a map wherein the driving speeds of the step motors 29A and 29B corresponding to the position of a feeling regulating knob 49 are determined. Thereby, during deceleration, a fluctuation speed for each of eccentric amounts of pintles 14 and 32 is varied according to the position of a feeling regulating knob 49. This constitution causes proper variation of a deceleration feeling.</p> |
