Abstract
The invention provides a magnetic levitation free film type air spring limiting device, and belongs to the technical field of magnetic levitation vehicles. Over-large displacement of an air spring of an existing magnetic levitation vehicle during operation can happen, so that operation stability and safety can be affected. Air spring horizontal limiting blocking parts are arranged on both sides in the middle of a longitudinal beam. Air spring longitudinal limiting blocking parts are arranged on inner sides of both edges of a bottom seat of a slide table unit. Thin steel plates are arranged on two sides of an upper push plate of an air spring. The thin steel plate and the air spring longitudinal limiting blocking parts are all provided with small holes. Steel cables penetrate through the small holes and are connected. The three-direction limiting device is formed, the air spring can be effectively protected so that the dynamics performance of the air spring can be fully achieved, and operation stability and safety of a magnetic levitation vehicle can be improved. The magnetic levitation free film type air spring limiting device is mainly used for magnetic levitation vehicle air spring limiting.
Description
Technical field
The invention belongs to the maglev vehicle technical field, particularly free diaphragn type air spring is to inhibiting device.
Background technology
The secondary suspension of current many guideway vehicles adopts air bellow, and its major advantage is: the rigidity of air bellow can be selected low value, to reduce the natural frequency of vibration of vehicle; Air bellow has nonlinear characteristic, can be designed to according to the needs of Vehicular vibration performance have more satisfactory elastic characteristic curve; The rigidity of air bellow changes with load, thereby in the time of can keeping sky, loaded vehicle, the natural frequency of vibration of car body is almost equal, and the running stability of empty and load different conditions is approached; Air bellow can bear 3 simultaneously to load, and larger radial deformation capabilities is arranged; Have good absorbing high-frequency vibration and sound insulation value.
different from the common rail vehicle, three traveling unit of maglev vehicle are that LF is connected with car body with slide unit by two, and air bellow has adopted a kind of large capacity free diaphragn type air spring, has dynamic performance preferably, but this air bellow self does not configure inhibiting device, when vehicle at too small curve or be subject to larger Lateral Force, start braking, acceleration-deceleration and vertical jolting when larger, displacement by a relatively large margin will occur in air bellow, not only can affect giving full play to of air bellow performance, also can affect the riding quality of vehicle, threaten traffic safety.Therefore this invention is on the basis that does not change maglev vehicle air bellow structure; set up air bellow three-dimensional inhibiting device; prevent that vehicle from producing excessive displacement at operational process Air spring; not only play the effect of protection air bellow, and can improve stationarity and the safety of vehicle operating.Set up the three-dimensional inhibiting device of air bellow on the basis that does not change existing air bellow structure; so that maglev vehicle respectively being limited within limits to displacement at operational process Air spring; give full play to the effect of air bellow and play the effect of protecting air bellow, thus the running stability and the safety that improve vehicle.
Middle low-speed maglev train has adopted a kind of large capacity free diaphragn type air spring, has dynam preferably
Characteristic, however this air bellow self does not configure inhibiting device, produces excessive displacement for fear of air bellow, has developed air bellow 3 to inhibiting device.
Summary of the invention
The purpose of this invention is to provide a kind of maglev vehicle free diaphragn type air spring inhibiting device, it can solve the larger problem of air bellow displacement that occurs in the maglev vehicle operational process effectively.To prevent that maglev vehicle from displacement by a relatively large margin occurring and then affecting riding quality and the safety of vehicle at operational process Air spring.
The present invention realizes its goal of the invention, the technical scheme that adopts is: a kind of maglev vehicle free diaphragn type air spring inhibiting device, it is characterized in that: air bellow is installed on longeron by rubber metal pad, both sides, longeron middle part are equipped with air bellow cross spacing backstop, the inboard, base both sides of slide unit unit is equipped with air bellow longitudinal spacing backstop, both sides at the upper plate of air bellow are provided with sheet steel, sheet steel and air bellow longitudinal spacing backstop all have aperture, and cable wire passes described aperture and connects.
Compared with prior art, the invention has the beneficial effects as follows:
1. due to the cross spacing backstop that has increased air bellow; in the time of can making vehicle at too small curve or be subject to larger Lateral Force; air bellow is limited within limits with respect to the cross travel of longeron; play the effect of protection air bellow, also improved lateral ride comfort and the travel safety of maglev vehicle.
2. due to the longitudinal spacing backstop that has increased air bellow; can make vehicle when starting braking or acceleration-deceleration; the longitudinal travel of air bellow is limited within limits; what can reduce to produce in the maglev vehicle operational process vertically rocks; the effect of playing the protection air bellow is arranged, and can improve passenger's ride quality.
3. due to the vertical inhibiting device of having set up air bellow; can make vehicle when vertical the rocking that occurs by a relatively large margin; the vertical deviation of air bellow is limited within limits, can protect air bellow by actv., and can improve the vertical running stability of maglev vehicle.
Cable wire is connected the air bellow upper plate with aperture on longitudinal spacing backstop by the aperture on steel plate with longitudinal spacing backstop, to realize the vertical spacing of air bellow.
The present invention is described in further detail below in conjunction with accompanying drawing and concrete embodiment.
