Problems solved by technology

If this happens, the steering angles of the two front wheels of the forklift will be inconsistent, thereby increasing the walking resistance of the forklift. In severe cases, the forklift will not be able to walk and it will be difficult to work normally.

Embodiment Construction

[0010] As shown in Figure 1, the forklift steering balance device of the present invention includes a fuel tank 8, a full hydraulic steering gear 6 and two oil cylinders 2, and the full hydraulic steering gear 6 is provided with a pressure oil inlet P, an oil return port T and two working oil Mouth 5. The oil tank 8 is processed with an oil inlet and an oil outlet. The oil outlet is connected to the pressure oil inlet P of the full hydraulic steering gear 6 through an oil pump 7, and the oil inlet is connected to the oil return of the full hydraulic steering gear 6 through a filter 1. Port T is connected. Among the two oil cylinders 2, the rodless chamber of one oil cylinder 2 communicates with the rod chamber of the other oil cylinder 2 by means of the pipeline 3, while the rod chamber and the rodless chamber of the two oil cylinders 2 that are not connected are respectively connected with the whole cylinder. The working oil ports 5 of the hydraulic steering gear 6 communica...

Abstract

The invention discloses a forklift steering balancing device which includes an oil box, a full hydraulic steering device and two oil cylinders. The oil outlet of the oil box is connected with the pressure oil inlet of the full hydraulic steering device by an oil pump; the oil inlet of the oil box is connected with the return opening of the full hydraulic steering device by a filter. The forklift steering balancing device is characterized in that the rod-free cavity of one oil cylinder is communicated with the rod cavity of the other oil cylinder by a pipeline; while the rod cavity and the rod-free cavity of the two oil cylinders are respectively communicated with one working oil opening of the full hydraulic steering device. The two ends of the piston of each oil cylinder are provided with blind holes used as valve cavities; all the blind holes are provided with a valve consisting of a top rod, a spring and a spherical valve core. The outer end of the top rod extends out of the corresponding end of the piston. A radical hole is arranged between the two blind holes; the two ends of the radical hole are respectively communicated with the two blind holes. The forklift steering balancing device can be used for reducing the walking resistance of the forklift and ensuring the forklift can work normally. Besides, the forklift steering balancing device can be used for controlling the steering of the two front wheels of the forklift.

Description

technical field [0001] The invention relates to a hydraulic control device. Specifically, it is a forklift steering balance device used to control the steering of the two front wheels of the forklift. Background technique [0002] At present, the hydraulic control device used to control the steering of the two front wheels of the forklift includes a fuel tank, a full hydraulic steering gear and two oil cylinders. The full hydraulic steering gear has a pressure oil inlet, an oil return port and two working oil ports. The oil tank has an oil inlet and an oil outlet. The oil outlet is connected to the pressure oil inlet of the full hydraulic steering gear through an oil pump, and the oil inlet is connected to the oil return port of the full hydraulic steering gear through a filter. The two oil cylinders are mutually independent, and their oil inlets and oil outlets are respectively connected with the working oil port and the oil return port of the full hydraulic steering gear....
