Abstract
The invention discloses a steel three-part control pattern structure steering rack with self-guide device, which loads self-guide device on the traditional three-part steel steering rack with elastic device between self-guide device and lateral rack.
Description
(1) technical field:
Large axle load bogie relates to the railway freight traffic device, especially meets the bogie truck that the international combined transport railway truck is used.
(2) background technology:
Aspect heavy haul transport, increasing the load-carrying of vehicle bicycle is to improve one of important channel of conveying efficiency.According to foreign experience, strengthening vehicle axle weight is inexorable trend.The lorry of american railway about 65% adopts F axle (the heavy 29.18t of axle), and part adopts G axle (the heavy 35.17t of axle); The heavy 35t that brought up to of the axle of Australia BHP heavy-haul line; The heavy 30t that reached of the axle of neat this heavy haul railway of Brazil's OK a karaoke club; The heavy 26t (narrow gauge) that reached of South Africa heavy haul railway axle; Sweden's heavy haul railway has weighed axle and has brought up to 30t by 25t; Russia has generally adopted the 23.15t axle heavy, and steps up to study the track parts that are applicable to that the 35t axle is heavy.
For integrating with the development of international railway lorry, open up international heavy axle load wagon market, development meets the heavily low wheel-rail force roller bearing adapter stabilizer bar of macro-axis of AAR standard, satisfy railway line for freight traffic and start the needs of ten thousand tons of trains, for China's next step exploitation macro-axis roller bearing adapter stabilizer bar heavy, function admirable lays the foundation, the development large axle load bogie is imperative simultaneously.
Unsprung weight is big, and wheel-rail force is big during by curve, and wheel-rail wear is serious, is the difficulty that the exploitation large axle load bogie must overcome, and has implacable contradiction between the bogie truck curving performance all the time and improve the bogie truck movement vibration stability and improve.Along with the heavy increase of axle, the raising of speed, what the wheel-rail wear problem will certainly be more serious reflects.In the service life of wheel-rail wear aggravation the shortening greatly wheel, track, cause the service expenditure of wheel, track sharply to increase.And wheel to and bogie side frame between springing in train travelling process, easily produce electrostatic phenomenon, can influence the in-use performance of bogie truck greatly.The patent No. a kind of railway goods train bogie that has been 99248108 patent disclosure, it comprises that wheel is to, bogie side frame, bolster, shock absorption device and adapter, it has two strut bars intersections to pass the preformed hole of bolster belly, and the secondary framework at strut bar two ends and two diagonal angles flexibly is connected as a single entity.This bogie truck has been obtained certain effect on smooth running and minimizing wheel-rail wear, but because the defective in the design, the problem of above-mentioned existence is still solved at all, and has produced other abrasion and maintenance issue.
(3) summary of the invention:
The problem to be solved in the present invention is exactly to provide a kind of at above deficiency and reduce wheel-rail force, reduce wheel-rail wear, increase the bogie truck that axle is heavy, maintenance is convenient, can eliminate springing static.
It adopts following technical scheme:
It comprises wheel to, bogie side frame and bolster, and wheel is to being connected and composed by axletree by left and right two wheels, and the two adjacent groups wheel constitutes bogie truck to laying respectively at the both sides of bolster.Its gordian technique is that secondary framework is installed on the bearing at the right axletree two ends of wheel, the two ends that are secondary framework are installed in respectively on the bearing at axletree two ends, secondary framework is connected by the pull bar that passes from the bolster middle part, and secondary framework and the pull bar that is attached thereto are formed the device of guiding certainly of bogie truck.At the two ends of secondary framework suit bogie side frame, between bogie side frame and secondary framework, springing is installed, in the chute of bogie side frame, brake beam is installed, the check weighing valve is installed between bogie side frame and the bolster.
Compared with prior art the present invention has following beneficial effect:
The creep power that produces between wheel track when 1, utilizing bogie truck to enter curve by the effect of bogie truck self guide mechanism, makes two wheels of bogie truck enter the curve radial position to " automatically ", thereby passes through curve smoothly.Because it is right that the right directional tagging of front-wheel will draw, pressure passes to trailing wheel by pull bar, add the existence of a series of springings, make this bogie truck have less bending stiffness, allow before and after the bogie truck two-wheeled to the splayed angle of shaking the head is arranged on curve, but do not allow wheel to diamonding being arranged with bogie side frame, guaranteed wheel to radial position by curve, thereby reduce wheel-rail force.Can keep steering framing wheel to enough vertical and horizontal locating stiffnesses are arranged in the time of simultaneously on the straight line circuit again, with the raising critical speed of crawling.Thereby find out that it has improved the stability of bogie truck cross motion, and improved the bogie truck curving performance, improve the bogie truck movement vibration stability and improve contradiction between the bogie truck curving performance thereby solved well, wheel-rail force reduces significantly, wheel rim realizes not having abrasion substantially, and the maintenance cost of bogie truck and track significantly reduces;
2, secondary framework 9 of the present invention adopts the inblock cast structure, and is simple in structure, the structural strength height, and casting is easily, and is easy to process;
3, the inboard employing in secondary framework 9 two ends of the present invention is U word box type construction, not disassembling under the situation of the device 4 that leads, makes things convenient for the replacing of brake beam 16.
What 4, springing 5 of the present invention adopted is rubber pad, suitable vertical, vertical and horizontal rigidity can be provided, and install plain conductor additional at the upper and lower end of base 11, can eliminate static.
5, bogie truck of the present invention adopts check weighing valve 7, can be under the load-carrying condition, and the deflection value that bolster is descended is proportional with the weight that increases on bolster, changes the braking force that comes the control brake cylinder to produce by amount of deflection.
6, this bogie structure modern design, the structural strength height, the complete machine assembling is overhauled conveniently easily.
7, this bogie truck is particularly suitable for curve than the use of the high-speed overload vehicle on the multi-line, has higher technological value.
