In order to address the above problem, the utility model is achieved through the following technical solutions:
Novel side shifter oil cylinder of the present utility model, it comprises piston-rod assembly, dust ring, back-up ring, seal ring, wrapped bearing bush, angle coupling, back-up ring, O RunddichtringO, cylinder barrel, supporting ring, seal ring, rectangle jump ring, flow regulator pieces, end cap assembly, catch and circlip for hole, piston and piston rod interference fit in the described piston-rod assembly, described Sealing and supporting ring are packed in the piston channel, and dust ring, back-up ring, seal ring, wrapped bearing bush, back-up ring, seal ring, catch, circlip for hole are encased in the cylinder cap assembly; Piston-rod assembly is packed in the cylinder barrel, the cylinder cap assembly is connected with the rectangle jump ring with cylinder barrel, angle coupling, flow regulator pieces install on the cylinder cap assembly, angle coupling connects one group of fork truck oil circuit, pushing piston bar assembly is done the bidirectional reciprocating motion under the effect of fork truck hydraulic coupling, realizes the left and right side shifting function of side shifter.
Further, described oil cylinder cap assembly oil duct, it connects the cylinder barrel side and is designed with a steel ball, blocks this side oil duct, and designs a side opening at homonymy, realizes the perforation of described cylinder cap assembly oil duct.
Further, described plunger designs has Step Shaft, and described cylinder cap assembly connects the cylinder barrel side and is designed with the step hole that matches with described Step Shaft.When moving to end of travel, hydraulic cylinder assembly can automatically reduce motion speed in order to effectively protect the goods of institute's load on the fork lift side shifter.
Compared with prior art; the beneficial effects of the utility model are: its plunger designs of the utility model has Step Shaft; the step hole that the end cap assembly is designed with the oil duct side opening and matches with the piston Step Shaft; when moving to end of travel, it can automatically reduce motion speed until slowly stop; inertial impact force is little; can effectively protect the goods of institute's load on the fork lift side shifter, improve the Security in the freight handling process.In addition, piston-rod assembly adopts a kind of novel processing method in the oil cylinder, and namely piston is fixed on the piston rod by special frock precise positioning and interference fit in the piston-rod assembly, and the piston-rod assembly scrappage is low, processing is simple, and manufacturing efficiency significantly improves.
The utility model fork truck directly is installed on the fork lift side shifter related components by the end cap assembly with novel side shifter oil cylinder, and simple, convenient disassembly are installed.
Description of drawings
Fig. 1 is the main sectional view of the novel side shifter oil cylinder of the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
