Abstract

The invention discloses a single-pump hydraulic system for a forklift, which includes a lifting cylinder, a tilting cylinder and a steering cylinder, and a gear pump providing high-pressure oil for the lifting cylinder, the tilting cylinder and the steering cylinder; Oil tank, multi-way reversing valve and full hydraulic steering gear, the oil inlet end of the gear pump is connected to the oil outlet end of the hydraulic oil tank, the oil outlet end of the gear pump is connected to the multi-way reversing valve, and the The multi-way reversing valve is connected to the oil return end of the hydraulic oil tank, the lifting cylinder, the tilting oil cylinder and the steering oil cylinder are all connected to the multi-way reversing valve, and the multi-way reversing valve The full hydraulic steering gear is also connected between the steering valve and the steering oil cylinder. The single-pump hydraulic system for a forklift according to the present invention has lower manufacturing costs, lighter and more comfortable operation, and improved production efficiency.

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 ...
