Abstract

The invention discloses a single-pump hydraulic system used for a forklift. The single-pump hydraulic system comprises a hoist cylinder, an oblique cylinder, a steering cylinder and a gear pump which is used for supplying high-pressure oil fluid to the hoist cylinder, the oblique cylinder and the steering cylinder; the single-pump hydraulic system further comprises a hydraulic oil tank, a multi-way reversing valve and a full-hydraulic steering gear; the oil inlet end of the gear pump is connected with the oil outlet end of the hydraulic oil tank; the oil outlet end of the gear pump is connected with the multi-way reversing valve; the multi-way reversing valve is connected with the oil return end of the hydraulic oil tank; the hoist cylinder, the oblique cylinder and the steering cylinder are all connected with the multi-way reversing valve; and the full-hydraulic steering gear is connected between the multi-way steering valve and the steering cylinder. According to the single-pump hydraulic system used for the forklift disclosed by the invention, the production and manufacture cost is lowered; the operation is more convenient and comfortable; and the production efficiency is improved.

Description

technical field [0001] The invention relates to a single-pump hydraulic system for a forklift, in particular to a working device with an integrated structure used in the hydraulic system of a forklift, and belongs to the technical field of forklift manufacturing. Background technique [0002] Hydraulic transmission control is a flexible and convenient control method often used in the forklift manufacturing industry. It uses hydraulic pressure to complete the process of transferring energy. It uses pressurized fluid as the energy medium to realize automatic control of various machines. Hydraulic transmission uses components to form the various control circuits required, and then organically combines several circuits into a transmission system that completes certain control functions to complete energy transmission, conversion and control. [0003] At present, in the installation process of medium-tonnage forklifts, the traditional hydraulic system is usually used, which has ...
