The invention relates to an air spring vertical guide mechanism for a multi-bogie railway vehicle, which comprises an air spring and vehicle body connecting device, a spring, an abrasion plate, a roller, a shaft, rolling bearings and sealing retainers. The air spring and vehicle body connecting device is arranged in the middle of a mounting seat, the top of the connecting device is in a disk structure, and the lower portion of the connecting device is in a cylindrical structure. The spring is arranged in the air spring and vehicle body connecting device, the abrasion plate is arranged around the lower portion of the air spring and vehicle body connecting device, the roller is arranged on the outer side of the abrasion plate, the shaft is rested at the top of the roller, the rolling bearings are arranged at two ends of the shaft, and the sealing retainers are arranged at the two ends of the shaft. Compared with the prior art, the air spring vertical guide mechanism for the multi-bogie railway vehicle has the advantages that the problem of vertical displacement is solved while the problem of transverse stability can be solved after other structures are added properly, and novel bogies for multi-bogie railway vehicles can be jointly developed by railway vehicle enterprises to finally develop novel multi-bogie railway vehicles.
Description
Technical field
The present invention relates to mechanized equipment field, especially relate to a kind of air spring vertical guide mechanism for multi-bogie railway vehicle.
Background technology
In order to manufacture and design multi-bogie railway vehicle, the design as the secondary suspension system of one of running part critical mechanical parts is also a requisite link.The guideway vehicle of current operation adopts two bogie truck supporting way substantially, which advantage comparatively obviously namely by level curve and vertical curve easy relative to multi-steering frame, but shortcoming is also very outstanding: in high speed train uses, wheel load is larger relatively, lower wheel-rail impact is severe at a high speed, wheel-rail wear is serious, for ensureing vehicle operating performance, repair polishing with regard to constantly carrying out Xuan to wheel rail, rail wheel life is shorter; For heavy-duty vehicle, increase bogie truck quantity, under identical load-carrying, average wheel load-carrying can be reduced too, be also conducive to reducing the application force between wheel track, thus reduce wheel-rail wear, extend the wheel track life-span; In addition, same axis heavily under, can load-carrying be increased.When adopting the vehicle structure supported more than two bogie trucks, even cannot pass through as adopted existing its curving performance of secondary suspension mode to be deteriorated.For this problem, use existing pure air bellow or cylindrical coil spring to be just subject to great limitation, larger vertical deformation and the simple air bellow of cross travel and high round steel spring and other the pure spring mode occurred at present all cannot realize.Novel secondary suspension design employing order force way, ensures its good dynamic performance simultaneously, has two gordian techniquies to need to solve: one is lateral stability issues, and two is vertical Large travel range problems.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of air spring vertical guide mechanism for multi-bogie railway vehicle solving vertical Large travel range problem is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of air spring vertical guide mechanism for multi-bogie railway vehicle, this guiding mechanism is located on the mount pad that is made up of air bellow and roller, it is characterized in that, this mechanism comprises air bellow car body connecting device, spring, wearing plate, roller, axle, antifriction-bearing box and sealing backstop, described air bellow car body connecting device is located at the middle part of mount pad, this connecting device top is disc-shaped structure, bottom is cylindrical-shaped structure, described spring is located in air bellow car body connecting device, described wearing plate is located at the surrounding of air bellow car body connecting device bottom, described roller is located at the outside of wearing plate, described pedestal is located at roller-top, the two ends of axle are provided with antifriction-bearing box, described sealing backstop is located at the end on axle both sides.
The surrounding symmetric design of described air bellow car body connecting device bottom 4 planes, the outside of plane connects wearing plate, wearing plate top arranges the interface be connected with car body.
Described spring is air bellow or steel coil spring.
Described roller is longitudinally arranged on the outside of wearing plate, and the roller of the air bellow car body connecting device left and right sides has 3, and the roller of both sides, front and back has 2.
Described sealing backstop is made up of inside and outside two boards, is bolted and is fixed on mount pad.
Compared with prior art, the present invention is directed to two is that vertical Large travel range have developed this vertical guide mechanism, with retrain air bellow only have vertical freedom degree to ensure simultaneously its vertical deviation of relative rectilinear state reaches ± 65mm, thus solve vertical Large travel range problem, the for motor vehicle novel steering frame of multi-steering frame can be researched and developed, final development of new multi-bogie railway vehicle with each guideway vehicle cartel.
