Power units for all-round forklifts

Abstract

The invention discloses a power unit used for an omnibearing forklift. The power unit comprises a hydraulic system, a fastener (102), a frame (103), an omnibearing wheel (104), a rim (105), a bearing (106) and a driving motor (6), wherein the hydraulic system can provide energy for the power unit; the driving motor (6) is fixed on the frame (103) through the fastener (102); the rim (105) is installed on the frame (103); the driving motor (6) is connected onto the omnibearing wheel (104) through the bearing (106) and the fastener (102); and the omnibearing wheel (104) and the rim (105) are fixed through the fastener (102). During work, the driving motor (6) drives the bearing (106) to rotate, and the bearing (106) supports the omnibearing wheel (104) to rotate. According to the power unit used for the omnibearing forklift, a reducer is omitted; the structure is simplified; installation steps are reduced; the cost is reduced; and hydraulic oil can be provided for the driving motor rapidly and stably, so that the omnibearing forklift can output power freely.

Description

technical field [0001] The invention relates to an omnidirectional forklift, in particular to a power unit for an omnidirectional forklift. Background technique [0002] Forklifts are industrial transport vehicles, which generally refer to various wheeled transport vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. The International Organization for Standardization ISO / TC110 is called industrial vehicles. Forklifts are often used for the transportation of large objects in storage, and are usually driven by fuel engines, batteries or hydraulic systems. Since the working environment of forklifts is usually in a narrow space such as warehouses and workshops, and at the same time, forklifts need to frequently move in various directions during use, this requires the use of full-scale forklifts. All-round refers to within the 2D plane, A driving method that can move directly in any direction, which makes the forklift extremely dema...

AI Technical Summary

Problems solved by technology

The existing mechanism is too loose to be suitable for the transmission in the all-round forklift

[0004] In addition, the disadvantage is that, for the hydraulic system of the all-round forklift, first of all, the gear pump is used in the hydraulic system, which is a quantitative pump, and the ordinary valve (switch valve) is matched with it. At this time, because such an ordinary valve usually cannot quickly and prepare to control the output hydraulic displacement according to the strength of the driver, and when the driver starts the pump, the valve may be fully opened, and when the pump is stopped, the valve will be completely closed. Fully open and fully closed situations result in wasted power absorbed by the pump

[0005] Secondly, accumulators are used in the hydraulic system that provides power, and due to the different weights of goods carried by omnidirectional forklifts, there may be various driving gears for driving force, but the hydraulic system of general omnidirectional forklifts cannot provide corresponding A variety of pressure adjustment levels, if you always use one pressure adjustment level, in the case of different weights, if there is no suitable corresponding pressure adjustment level, it will either lead to waste of power, or cause shocks in the hydraulic system Possibility, severe cases will lead to damage to hydraulic components

[0006] Third, most of the current hydraulic systems of all-round forklifts use ordinary valves (switch valves) to directly provide pressure oil for hydraulic motors to control the driving force unit. When working, the goods cannot be moved quickly, and the work efficiency is impaired
