Description
Technical field
The utility model relates to a kind of pipeline hydraulic fluid port connection structure for heavy duty truck steering swivel system, belongs to field, commercial vehicle/comm..vehicle chassis.
Background technology
The steering swivel system pipeline hydraulic fluid port connection mode of heavy duty truck is all the time is mostly adopt articulation connection mode.Steel pipe and partial high pressure flexible pipe many employings hollow bolt add articulation and the tightening seal washer of welding, and low pressure hose many employings hollow bolt adds swivel joint and fixes with clip.In the fitting process of pipeline, because parts are many, assembling trouble; Meanwhile, with the increase of focusing on card steering swivel system load, the pressure of steering swivel system constantly promotes, articulation is low due to transmission efficiency, generates heat serious simultaneously, causes heavily card steering swivel system leakage of oil, heating is serious, and damage steering hydraulic element, reduces the reliability of steering swivel system.Large-tonnage special purpose vehicle is needed even to adopt to steering swivel system the core Hydraulic Elements that step-down coupling removable parts are large, or increases the heat radiation of steering hydraulic cooling system in addition, steering swivel system cost is increased suddenly.
Utility model content
For solving the problems of the technologies described above, the utility model aims to provide a kind of pipeline hydraulic fluid port connection structure for heavy duty truck steering swivel system, improve heavily card and turn to pipeline efficiency of assembling, reduce fluid running resistance, solve steering swivel system Leakage, meanwhile, steering swivel system fluid heat dissipation problem obtains and improves to a certain extent, improve the reliability of steering swivel system greatly, bring larger economic benefit to car load.
For achieving the above object, the utility model provides a kind of pipeline hydraulic fluid port connection structure for heavy duty truck steering swivel system, it comprises Hydraulic Elements hydraulic fluid port end, steel pipe, flexible pipe, Hydraulic Elements hydraulic fluid port end, steel pipe and flexible pipe connection structure each other in the following way:
When Hydraulic Elements hydraulic fluid port end is connected with steel pipe, Hydraulic Elements hydraulic fluid port end arranges the ferrule fitting with cutting ferrule screw thread, one end riveted joint cutting ferrule of steel pipe and cutting ferrule nut, and wherein cutting ferrule is spirally connected with the ferrule fitting with cutting ferrule screw thread;
When Hydraulic Elements hydraulic fluid port end is connected with flexible pipe, ferrule fitting is withheld at flexible pipe two ends, is spirally connected with the joint with cutting ferrule screw thread of Hydraulic Elements hydraulic fluid port end;
When steel pipe is connected with steel pipe, respectively weld ferrule fitting in an end of two steel pipes, the two ends of connecting leg nut are spirally connected the ferrule fitting of two steel pipes respectively;
When steel pipe is connected with flexible pipe, the welding edges ferrule fitting of steel pipe, ferrule fitting nut is withheld in the end of flexible pipe, and wherein ferrule fitting and ferrule fitting nut are spirally connected.
The technique effect that the utility model realizes: the hydraulic fluid port of steering swivel system connects the connection mode all adopting ferrule fitting, and amount of parts is few, assembling is simple, and the clamp nut of the ferrule fitting of band angle all can 360 ° of rotation directions, are beneficial to pipeline and move towards smooth and easy.Meanwhile, ferrule fitting good airproof performance, fluid-pressure transmission efficiency is high, and generate heat little, efficiency is high, and withstand voltage height substantially increases the reliability of steering swivel system.
Accompanying drawing explanation
Fig. 1 is the utility model Hydraulic Elements hydraulic fluid port end, connection structure schematic diagram between steel pipe and flexible pipe.
Fig. 2 is the connection structure schematic diagram between the utility model Hydraulic Elements hydraulic fluid port end and flexible pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As illustrated in fig. 1 and 2, a kind of pipeline hydraulic fluid port connection structure for heavy duty truck steering swivel system, it comprises Hydraulic Elements hydraulic fluid port end, steel pipe, flexible pipe, Hydraulic Elements hydraulic fluid port end, steel pipe and flexible pipe connection structure each other in the following way:
When Hydraulic Elements hydraulic fluid port end is connected with steel pipe, Hydraulic Elements hydraulic fluid port end arranges the ferrule fitting 1 with cutting ferrule screw thread, one end riveted joint cutting ferrule 2 of steel pipe 3 and cutting ferrule nut, and wherein cutting ferrule 2 is spirally connected with the ferrule fitting 1 with cutting ferrule screw thread;
When Hydraulic Elements hydraulic fluid port end is connected with flexible pipe, ferrule fitting is withheld at flexible pipe 6 two ends, is spirally connected with the joint 1 with cutting ferrule screw thread of Hydraulic Elements hydraulic fluid port end;
When steel pipe is connected with steel pipe, respectively weld ferrule fitting 4 in an end of two steel pipes, the two ends of connecting leg nut (not shown) are spirally connected the ferrule fitting 4 of two steel pipes respectively;
When steel pipe is connected with flexible pipe, the welding edges ferrule fitting 4 of steel pipe 3, ferrule fitting nut 5 is withheld in the end of flexible pipe 6, and wherein ferrule fitting 4 and ferrule fitting nut 5 are spirally connected.
Wherein, ferrule fitting is the metric thread joint meeting ISO 6149 standard, and its clamp nut of ferrule fitting for 90 ° or 45 ° can select 360 ° of tunings.
Wherein, hose end can select the metric system negative thread ferrule fitting nut withholding 24 °, band cone.
The above, for the person of ordinary skill of the art, can make various corresponding change and distortion according to technical conceive of the present utility model, and all these change and are out of shape the protection domain that all should be considered as the utility model claim.
