Rear-wheel steering system and rear-wheel steering angle detection system of electric three-wheel forklift

摘要

The present invention can appropriately detect the rear wheel steering angle by adding an analog type volume in the rear wheel steering apparatus of the electric three-wheel forklift having the structure that can reliably transmit the steering force to the rear wheel side by improving the conventional structure To a rear wheel steering angle detecting apparatus.;Conventionally, the steering range is too large and the detection range of the rear wheel steering angle is limited by using a limit switch. In the present invention, a structure is adopted in which a rack is provided at the center thereof by using one cylinder and the pinion steers the frame In this structure, a volume assembly having an analog volume is formed at the upper end of the frame, so that the steering force can be surely transmitted. In addition, the steering angle of the rear wheel can be precisely detected to appropriately control the motor attached to each of the front wheels Safe and smooth steering.
