The connecting rod is of the integral cast type structure, the double-neck ball heads are directly cast at the two ends of the connecting rod, and the cross section of the connecting rod is in a cross shape. The cast thrust rod has the advantages that under the premise that the strength requirement of the connecting rod is met, the cross section of the connecting rod is designed to be in the cross shape, so that the weight of the cast thrust rod is greatly reduced, and lightening of the truck is facilitated.
Description
Technical field
The present invention relates to automotive parts technical field, particularly relate to a kind of balanced suspension for heavy-duty vehicle casting propelling rod.
Background technology
At present, the equalizing suspension system that domestic and international most of heavy motor vehicle adopts is all the equalizing suspension system of rod member interconnection system.Along with the continuous deterioration of the enforcement of domestic axle load method, the implementation of " weight metering charging " and environmental quality especially air quality, heavy motor vehicle is as one of the arch-criminal of broken ring air quality, energy-saving and emission-reduction just have to be brought into schedule, instantly how can improve cargo capacity can reduce costs again and accomplish energy-saving and emission-reduction, only try every possible means on reduction tare.Heavy motor vehicle improves carrying capacity mainly through increasing vehicle bridge (axle) quantity or vehicle bridge (axle) load-carrying capacity, and its guiding mechanism propelling rod, as one of 3 critical components of balance suspension, must carry out corresponding optimal design in structure design intensity.
Heavy motor vehicle propelling rod mainly contains welding, hot riveting structure and the casting of whole bar.Welding propelling rod is because of the restriction by welding material and domestic welding process level, and easily occur the solid phenomenon of not prison welding, constant product quality is poor; Hot riveting technique easily causes burning or Repeat-heating phenomenon in heat process, the embrittlement of propelling rod material generation coarse grains, structure and toughness is caused to reduce, thus affect in-use performance, great noise can be produced in the process of rivet hot simultaneously, certain injury can be caused to operator.And a kind of rod body of thrusting rod disclosed in Chinese utility model application numbers 201120355370.9, comprise bar portion and two neck bulb, described bar portion comprises an integrally-built pipe link, described pipe link two ends all once form described pair of neck bulb, in the utility model, described pipe link is one piece casting type structure, and pipe link two ends directly cast out described pair of neck bulb, and the cross-sectional plane of described pipe link is I shape.The utility model structure is simple, and part reduces, and technological process is shortened, and greatly reduce weight while proof strength, saved cost, the width between centers precision of two neck bulb pin-and-hole improves greatly.
But in use, find that one piece casting type pipe link disclosed in this patent still exists the excessive shortcoming of weight, requirement heavy motor vehicle pipe link being reduced further to weight can not be met.
Summary of the invention
In view of above content, the invention provides a kind of balanced suspension for heavy-duty vehicle casting propelling rod.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of balanced suspension for heavy-duty vehicle casting propelling rod, comprise bar portion and two neck bulb, described bar portion comprises an integrally-built pipe link, described pipe link two ends all once form described pair of neck bulb, described pipe link is one piece casting type structure, and pipe link two ends directly cast out described pair of neck bulb, the cross-sectional plane of described pipe link is cross.
Further, described cross-sectional plane comprises the first rectangular stub of surrounding, the second rectangular stub, the 3rd rectangular stub and the 4th rectangular stub; Described first rectangular stub is symmetrical arranged up and down with the 3rd rectangular stub and shape is identical, and described second rectangular stub is symmetrical set with the 4th rectangular stub and shape is identical; Described first rectangular stub is identical with the length of the second rectangular stub; The width of described first rectangular stub is greater than the width of the second rectangular stub.
Further, corners process is carried out in the front end of described first rectangular stub, the second rectangular stub, the 3rd rectangular stub and the 4th rectangular stub.
Further, described first rectangular stub, the second rectangular stub, the 3rd rectangular stub and the 4th interconnective position of rectangular stub are by corners transition.
Due to the utilization of technique scheme, the present invention compared with prior art has following beneficial effect:
Under the requirement ensureing pipe link intensity, the cross-sectional plane of pipe link is designed to cross, thus significantly reduces the weight of these parts, be beneficial to the lightweight of vehicle.

Detailed description of the invention
Below in conjunction with specific embodiment, content of the present invention is described in further detail:
A kind of balanced suspension for heavy-duty vehicle casting propelling rod, comprise bar portion 1 and two neck bulb 2, described bar portion comprises an integrally-built pipe link 11, described pipe link two ends all once form described pair of neck bulb, described pipe link is one piece casting type structure, and pipe link two ends directly cast out described pair of neck bulb, the cross-sectional plane 3 of described pipe link is cross.
Described cross-sectional plane comprises the first rectangular stub 31, second rectangular stub 32 of surrounding, the 3rd rectangular stub 33 and the 4th rectangular stub 34; Described first rectangular stub is symmetrical arranged up and down with the 3rd rectangular stub and shape is identical, and described second rectangular stub is symmetrical set with the 4th rectangular stub and shape is identical; Described first rectangular stub is identical with the length of the second rectangular stub; The width of described first rectangular stub is greater than the width of the second rectangular stub.
Corners process is carried out in the front end of described first rectangular stub, the second rectangular stub, the 3rd rectangular stub and the 4th rectangular stub.
Described first rectangular stub, the second rectangular stub, the 3rd rectangular stub and the 4th interconnective position of rectangular stub are by corners transition.
In order to the optimization of a kind of balanced suspension for heavy-duty vehicle of the present invention casting propelling rod for a kind of rod body of thrusting rod effect disclosed in Chinese utility model application numbers 201120355370.9 is described.Catia software is utilized to set up the model of these 2 kinds of structures respectively, material is set to QT450, when analyzing operating mode one normal vehicle operation or vertical bounce bar suffered by propelling rod to pulling force (consulting Fig. 4) and operating mode two vehicle bridge relative to body side to rolling radial twist moment (consulting Fig. 5) suffered by propelling rod.
As shown in Figure 6, can find out and finally determine that a kind of balanced suspension for heavy-duty vehicle of the present invention casting propelling rod is except bar is to tensile stress and bar to except deflection increase a little for the moment in operating mode, its radial tersional stress when weight and operating mode two is far superior to a kind of rod body of thrusting rod disclosed in Chinese utility model application numbers 201120355370.9.But the tensile strength Rm(450MPa relative to QT450) and yield strength Rp0.2(310MPa), the maximum rod of a kind of balanced suspension for heavy-duty vehicle casting of the present invention propelling rod, to tensile stress (201.66MPa) much smaller than the tensile strength of QT450 and yield strength, thus can ensure safe and reliable use.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
