Abstract
The invention relates to a pantograph spring for subway or urban rail vehicles, which is a cold coiling helical extension spring; two conductive contacts are respectively embedded at the two ends of the spring; the diameter of a spring steel wire is 17.3mm; and a Dacromet treatment layer and a surface spray coating layer are arranged on the surface of the spring. The pantograph spring adopts the single tension spring to raise a pantograph, adopts a cold coiling technology, uses the spring steel wire with the wire diameter of 17.3mm, and has the design initial tension of 1500N and the tensile rigidity of 40N/mm, thus meeting the power receiving requirements under the conditions of pantograph rise and high-speed running. The pantograph spring is stable in performances, light in design, reliable in surface anticorrosion and attractive in appearance. The single extension helical steel spring design is adopted, so that the weight is lightened, and the manufacturing cost is reduced. Due to the reliability of the performances of the pantograph spring, the power source of the subway or the urban rail vehicles can be guaranteed.
Description
Technical field
The invention belongs to electric tracks vehicle power receiving equipment.Be particularly related to a kind of subway, city rail vehicle pantograph spring, it is to be applied to bow that subway, city rail vehicle pantograph rise with the cold coiling helical steel springs that stretches.
Technical background
Traditional subway, city rail pantograph adopt two groups of inside and outside sleeve type extension spring rising bows.Volume is large, and needs to regulate the cooperation pulling force of two groups of springs, just can reach the left and right sides balance of pantograph.
Summary of the invention
The object of the invention provides a kind of subway, city rail vehicle pantograph spring, is to be applied to subway, city rail vehicle pantograph rising bow with the cold coiling helical steel springs that stretches, and guarantees that the power resources of subway, city rail vehicle are stable.
Content of the present invention is:
A kind of subway, city rail vehicle pantograph spring is characterized in that: it is a kind of cold coiling spiral stretching spring, studs with conductive contact at the two ends of spring, and the diameter of spring wire is 17.3mm.
There are Dacroment processing layer and surface spraying layer in the spring surface.
Characteristics of the present invention are:
The present invention adopts single-piece extension spring rising bow, adopts cold coiling to roll technology, uses the spring wire of wire diameter 17.3mm, and the design initial tension is 1500 newton, and tensible rigidity 40 Newton/millimeter can satisfy under rising bow and the high-speed cruising condition being subjected to electric requirement.Stable performance, light-weight design, surface anticorrosion is reliable, good looking appearance.The Reliability Assurance of its performance the power resources of subway, city rail vehicle.
Adopt the design of single-piece stretching helical steel springs, expendable weight reduces manufacturing cost.Adopt conveyor screw to add bolt tension, conveyor screw prevents that in diameter and pitch and spring interference fit conveyor screw from coming off when vehicle operating.For guaranteeing the stable of rising bow power, reduce the spring application stress, the spring design initial tension is 1500 newton.For guaranteeing the antiseptic property of spring inner ring, carry out the Dacroment surface anticorrosion before the employing spring assembling and process, adopt the stretching surface spraying after the assembling.
Description of drawings
Fig. 1 is subway, city rail vehicle pantograph spring schematic diagram.
Among the figure: 1 cold coiling spiral stretching spring, 2 conductive contacts.
The specific embodiment
A kind of subway as shown in the figure, city rail vehicle pantograph spring, it is a kind of cold coiling spiral stretching spring, studs with conductive contact at the two ends of spring, the diameter of spring wire is 17.3mm.
There are Dacroment processing layer and surface spraying layer in the spring surface.The conveyor screw diameter of conductive contact and pantograph spring inside diameter tolerance fit.The conveyor screw pitch of conductive contact and pantograph spring inside diameter tolerance fit.With the technology of initial tension, can bear the tensile force of 1.5KN after rolling.
Dacroment processings+surface spraying technology is adopted on spring surface, can slow down the spring rate of corrosion, prolongation spring service life.
