SWITCH-BACK CONTROL SYSTEM

摘要

PURPOSE:To improve the operation performance in switch-back operation by executing the connection control in which clutch is put into semiclutch for the time when the car speed is zero after an advance/retreat switching gear is switched, in the switch-back control for an industrial vehicle. CONSTITUTION:A load quantity reading part 1 for reading the loading quantity at present from the output signal of a load detecting sensor installed onto the bed of an industrial vehicle such as fork lift is provided. The clutch engagement quantity corresponding to the read-out loading quantity and the car speed at present is read out from a ROM in a clutch engagement quantity reading part 2, and outputted into a semiclutch control pat 3. A car speed detecting part 4 which reads out the car speed at present and detects the reduction of car speed to zero is provided. When an advance/retreat gear is switched, continuous control is carried out by putting the clutch into semiclutch by the above- described semiclutch control part 3.
