Energy-saving noise-reduction electric fork-lift truck hydraulic power steering system

The utility model discloses an energy-saving noise-reduction electric fork-lift truck hydraulic power steering system. The system comprises an operating mechanism and further comprises a steering device, a steering wheel arranged on a steering gear, a hydraulic motor and a hydraulic mechanism. The hydraulic mechanism comprises a gear pump for providing hydraulic oil and a pump motor for providing power for the gear pump. The hydraulic mechanism further comprises an oil storage tank for containing the hydraulic oil. A hydraulic oil input end of the gear pump is connected with the oil storage tank through a pipe. A hydraulic oil output end of the gear pump is connected with a hydraulic oil input end of the hydraulic motor through the steering gear by means of a pipe. A hydraulic oil output end of the hydraulic motor is connected with the oil storage tank through a pipe by means of the steering gear. The pipe for connecting the hydraulic oil output end of the gear pump and the steering gear is provided with a hydraulic sensor. The hydraulic sensor is electrically connected with a control module of the pump motor. By means of the energy-saving noise-reduction electric fork-lift truck hydraulic power steering system, the noise and energy consumption of the hydraulic power steering system can be lowered.
