Abstract

The invention relates to a full electric forklift, comprising a vehicle-mounted storage battery, a forklift drive device, a front upper arm rotating device, a forklift traverse drive device and a steering gear. The invention solves the technical problems of inconvenient installation, low transmission efficiency, low service life, high operation noise and low reliability of the existing battery forklift due to the adoption of a hydraulic drive system. The full electric forklift of the invention has the advantages of high conversion efficiency, long service life, no pollution to environment and low manufacture cost and the like.

Description

technical field [0001] The invention relates to a battery forklift, in particular to a battery forklift that uses an electric ball screw instead of hydraulic cylinders such as a fork drive cylinder, a front arm rotation cylinder, a steering cylinder, and a fork laterally moving cylinder. Background technique [0002] The power generation of the current battery forklift is provided by the fork drive cylinder, the front arm rotation cylinder, the steering cylinder, and the fork lateral movement cylinder. When the forklift is working, the motor drives the hydraulic pump to rotate, and then the hydraulic pipeline is connected to each oil cylinder, and the oil circuit is controlled by manual and electric valves. But the existing hydraulic system has the following problems: [0003] 1. The connection of the hydraulic pipeline is complex and prone to oil leakage and the installation of the system is inconvenient. [0004] 2. The efficiency of hydraulic transmission is low, so bat...
