Abstract
A kind of two stage stiffness formula elastomer group locking device, it has at least one little rigidity flexible member and a big rigidity flexible member, and little rigidity flexible member is arranged in elastomer pre-compression device and arranges with big rigidity elastic element series under the effect of precommpression load F1.This device has the hardest rear soft composite rigidity, during as railway vehicle axle box spring suspension device, there is bigger compression stiffness when deformational displacement amount is the least, and when deformational displacement amount reaches the numerical value set, its compression stiffness starts to diminish, thus efficiently solves its straight line and crawl the contradiction that critical velocity and curve passing through cannot be taken into account by performance.Simultaneously, this device applies also for the various occasions needing elastomer vibration absorber composite rigidity elder generation the softest between rolling stock associated components, to relax vehicle wheel-rail impact, to improve dynamics of vehicle performance, support vehicles operation safety, and then greatly improve the operation quality of rolling stock.
Description
Technical field
The present invention relates to elastomer buffering shock-absorbing device, be mainly used in railcar in particular to one
The two stage stiffness formula elastomer group locking device of buffer shock-absorbing between component.
Background technology
Rolling stock is a kind of special car run on ad hoc track, and it is transported along ad hoc track
Can automatic guide during row, it is not necessary to control direction.Bogie belongs to most important parts on rolling stock
One of, it supports whole goods weight and the weight of car body itself.Conventional bogie is bag mostly
Containing two side frame compositions and the research structure of a bolster composition, the two ends of side frame composition are led
Frame by axle box adapter and bearing arrangement be arranged on front and back wheel to composition on, bolster composition two
End is then arranged on by two groups of central mounting devices in the central square frame of side frame composition.Axle box carries
Saddle and bearing arrangement are contact side frame composition and the wheel movable joint to composition, and it makes wheel along rail
The rolling of road circuit is converted into the car body translation along track circuit, and can the most linearly circuit
Run and be smoothly through curve.
During rolling stock high-speed cruising in orbit, by existing for the shock and vibration supervening complexity
As.In order to reduce track circuit irregularity and wheel to the high-speed motion various dynamic shadow to car body
Ringing, such as impact of collision, vertical vibration, oscillation crosswise etc., those skilled in the art are according to various
The difference of vehicle condition, often arranges elastic vibration clamper between vehicle associated components.Such as exist
The side frame guide of bogie and wheel are to setting up axle box spring suspension device between composition, axle box is elastic
It is vertical that suspension arrangement generally comprises between axle box adapter end face and side frame guide bottom surface
Elastic device and the longitudinal elasticity device between axle box adapter and side frame guide two sides,
Can it run the most steadily at its straight line, pass through curve and ensure that vehicle safety is transported
The aspects such as row all play an important role.
Along with being continuously increased of rolling stock load capacity, vehicle self axle focuses on constantly increase, car
The speed of service is also improving constantly, and quality and the performance requirement of the bogie of car are the most more come by this
The highest.Under heavy duty fast state, it is easier to evoke car body during car wheel-set orbital motion
Yaw motion, cause vehicle riding quality to be greatly reduced, time serious, also can cause vehicle derailing
Accident.Meanwhile, vehicle can not be too big by wheel-rail lateral force during curve, and otherwise vehicle is also
There is the possibility of derailing.
And directly affect the rolling stock crawl critical operation speed and vehicle on straight line at song
One of critical component by performance on line is exactly indulging in above-mentioned axle box spring suspension device
To elastic device, the design of its planform and elastic stiffness parameter designing are most important.In order to carry
Critical operation speed of crawling when high vehicle runs on straight line is must be requested that its longitudinal register is firm
Degree is big；In order to make vehicle cross force when by curve between wheel track not too big, again
Ask its longitudinal register rigidity less.
At present, vehicle crawling critical operation speed and improving vehicle at curve on straight line is improved
On be conflict body by performance, in the specific design of above-mentioned longitudinal elasticity device be difficult to
Take into account.This is because:
Existing elastic device is generally by two or more elastomer series, parallel or string
And series-parallel connection is constituted.Such as: three shown in Fig. 1 elastomer K1, K2, K3 cascaded structure,
Shown in Fig. 2 three elastomer K1, K2, K3 parallel-connection structure, seven shown in Fig. 3 elasticity
Body K1～K7 serial-parallel mirror structure.The common feature of these elastic devices is: a combination thereof rigidity is led to
It is often linear rigidity or the least rear big rigidity, is generally the softest rear hard rigidity.When it
When being acted on by extraneous load p, the elastomer that rigidity is less can be first subject to load, produces
Bigger deformational displacement；Can be the most just that the elastomer that rigidity is bigger bears load, produce less
Deformational displacement.When being specifically applied in above-mentioned longitudinal elasticity device, by grouped by itself rigidity first
Restriction hard after soft, the increase of its deformational displacement amount is that linearly or equal proportion increases phase with load
Corresponding.So, it is impossible to take into account completely its straight line crawl critical operation speed big rigidity want
The summation curve passing through little rigidity requirement by performance, there is also the risk of train derailing simultaneously,
Greatly reduce the effect of its buffer shock-absorbing.
The most effectively promote straight line stationary performance and curve negotiating that heavy duty hot-short runs
Can, always those skilled in the art attempt the difficult problem solved, this battalion to improving rolling stock
Fortune quality, the security performance of guarantee rolling stock have important practical significance.
Summary of the invention
Present invention aim to provide a kind of two stage stiffness formula elastomer group locking device, its tool
There is the hardest rear soft composite rigidity, both can be applicable to axle box spring suspension device takes into account railcar
