Description
Technical field
The present invention relates to a kind of railway goods train bogie secondary suspension device, especially a kind of high speed railway roller bearing adapter stabilizer bar secondary suspension device.
Background technology
At present the railway bogie suspension gear generally has one to be and two be two types; Generally only establish single stage suspension device or secondary suspension device for traditional railway goods train bogie; For three piece truck, generally do not establish single stage suspension; And its central mounting is as its secondary suspension device, and this secondary suspension device is between bolster and bogie side frame.Then only establish the single stage suspension device for domestic lorry frame work steering frame, and the single stage suspension device be located at framework and the wheel between.Traditional lorry three piece truck and framework type bogie truck all adopt cartridge and the common mode of carrying of side bearing, and its steering resistance square is made up of cartridge friction resistance moment and side bearing friction resistance moment.And for speed per hour surpasses the bullet train bogie truck of 200km; It generally all is two stage suspension; Wherein secondary suspension mostly adopts technical measures such as air bellow, vertical oil-pressure damper, anti-snakelike shock absorber; The characteristics of this secondary suspension system are: air bellow is used for the vertical load of bearing body, and generally is located at the journal centre position, to improve the stationarity of vehicle; It is vertical cushioning performance that vertical oil-pressure damper is used to improve two of vehicle, adopts anti-snakelike shock absorber to be used to provide the steering resistance square of vehicle.
When 160km/h was following, bogie truck can not established the secondary suspension device to railway truck at running velocity, but when running velocity reached the running velocity grade of 200km/h, the traditional cartridge and the bearing mode of side bearing can not meet the demands.Running velocity be the bullet train of 200km/h sky, loaded vehicle difference are little because it has, the bogie truck cost control requires relatively flexibly, heavy less, the structure of bogie axle can relative complex etc. characteristics, so adopt the air bellow technology fine to having satisfied the requirement of passenger vehicle drive ability.But for the roller bearing adapter stabilizer bar of 200km/h speed class; Because railway truck has sky, the loaded vehicle difference is bigger; Manufacturing cost requires lower; Requirements such as bogie axle is heavy greatly, structural requirement is simple, easy to maintenance so adopt the design plan of bullet train obviously can not meet the demands, must adopt the brand new design plan to reach the basic demand of above-mentioned roller bearing adapter stabilizer bar.Present design puts forward under this background technology.
Can find out that from above-mentioned analysis 200km/h roller bearing adapter stabilizer bar secondary suspension Design of device principle is: (1) can adapt to lorry sky, characteristics that the loaded vehicle difference is bigger; (2) design plan can not increase considerably the bogie truck manufacturing cost; (3) can adapt to the heavy bigger characteristics of bogie axle; (4) structural requirement is simple, easy to maintenance; (5) can satisfy linear running stability and the curving performance of vehicle simultaneously in the specified speed grade.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned prior art; A kind of high speed railway roller bearing adapter stabilizer bar of brand new secondary suspension device is provided; This suspension gear can adapt to the speed class of the 200km/h of railway goods train bogie, the requirement of maximum allowable axle load 18t; And have adapt to empty, the loaded vehicle difference is big, low cost of manufacture, distinguishing feature such as simple in structure, easy to maintenance, satisfies linear running stability and the curving performance of vehicle in the specified speed grade simultaneously.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
A kind of high speed railway roller bearing adapter stabilizer bar secondary suspension device comprises that some two is rubber spring, two be rubber spring between framework two curb girders of bogie truck, two is that rubber spring is used to bear the vertical force load from car body.Two is that to be provided with some two be that horizontal backstop and two is vertical backstop the outside of rubber spring, has limited car body relative bogie truck maximum transversal displacement respectively and has sidewindered displacement.Two is that the vertical backstop outside is provided with that some to be arranged at two on the corresponding mount pad of car body be vertical oil-pressure damper and anti-snakelike shock absorber, and two is that the maximum that vertical oil-pressure damper has limited car body is sidewindered displacement, has improved vehicle and has sidewindered stability.Also be provided with some lateral dampers that are installed on the corresponding mount pad of car body on the bogie truck, the horizontal damping of vehicle when high-speed cruising mainly is being provided, improving vehicle linear running stability.Also be provided with the elastic safety chain on the framework of bogie truck, the elastic safety chain other end links to each other with car body, has prevented that the relative bogie truck of car body from producing the excessive vertical deviation of upwards beating, and guaranteed vehicle safety.
The present invention makes this roller bearing adapter stabilizer bar satisfy maximum allowable axle load 18t, the operating needs of maximum commercial operation speed 200km/h through adopting above gordian technique.Have characteristics simple in structure, easy to maintenance, lower-cost simultaneously.
The invention has the beneficial effects as follows that compared with prior art the present invention has the following advantages:
1. bogie truck secondary suspension device of the present invention is arranged on the full side bearing structure that two 2 between two curb girders are rubber spring owing to adopted, and can bear the vertical load from car body on the one hand, can improve the running stability of vehicle on the other hand.Two is that rubber spring is arranged on two curb girders inboard simultaneously; This design can be satisfied vehicle produces bigger corner through little curve time the requirement; Because two is that the rubber spring transverse pitch is less; Two is that the shear deformation that produces of rubber spring is not too large, thereby has guaranteed the design realizability and the product reliability of rubber spring.
Two be rubber spring to have less two be the lateral stiffness value, can relax from the transverse force excitation between the wheel track, improve the lateral direction of car operation stability.
3. the arranged outside at the secondary suspension spring has two to be that horizontal backstop and two is vertical backstop, and two is the maximum transversal displacement that horizontal backstop has limited the relative bogie truck of car body, and then prevents that two is that rubber spring produces excessive transverse shear deformation and damages.Two is that the maximum that vertical backstop has limited car body is sidewindered displacement, when preventing that vehicle from moving on curve, produces and excessive sidewinder displacement and turn on one's side, and has on the other hand to have avoided when two being that rubber spring can transmit the vertical force load from car body when losing efficacy.
4. being arranged at two is that two of the vertical backstop outside is vertical oil-pressure damper, mainly provides vehicle to sidewinder damping, has improved the stability of sidewindering of vehicle.
5. two is the lateral stability that lateral damper has improved vehicle, and the steering resistance square when anti-snakelike shock absorber provides the vehicle high-speed cruising provides the critical speed of vehicle.
6. the elastic safety chain can prevent effectively that the relative bogie truck of car body from producing the excessive displacement of upwards takeofing, and guaranteed the vehicle operating safety.
