Abstract
The utility model relates to a spherical bearing for a bogie of a linear motor vehicle, which comprises an outer sleeve and an inner body of the spherical bearing; the inner body of the spherical bearing comprises an inner sleeve, an elastic body and a core shaft which are integrated; the elastic body is between the inner sleeve and the core shaft; the core shaft is a columnar metal shaft and comprises columnar structures at two ends and a spherical structure in the middle; the elastic body is an annular rubber ring wrapped outside the spherical structure of the core shaft; and two through holes are also arranged on the columnar structures at two ends of the core shaft. The spherical bearing for the bogie of the linear motor vehicle disclosed by the utility model has the benefits that the inner body of the spherical bearing for the bogie of the linear motor vehicle is an integrated structure formed by heating the inner sleeve, the elastic body and the core shaft; the elastic body is rubber having good elasticity; the inner body and the outer sleeve of the spherical bearing commonly form the spherical bearing; the spherical bearing not only bears radial load but also bears a certain axial effect; in addition, due to design of the rubber profile, the spherical bearing can achieve performance requirements while bearing radial load.
Description
Technical field
The utility model relates to a kind of component of track train, relates in particular to a kind of spherical bearing.
Background technique
Spherical bearing is the vitals of city railway train, and it will improve travelling comfort, the stability of vehicle, possess suitable rigidity requirement, satisfies the vibration isolation of system, the technical requirements of buffering; Spherical bearing also should possess certain intensity with the load requirement of the different operating modes of adaptive system; Should have certain fatigue behaviour, satisfy the requirement of system's operation.At present, do not satisfy the linear electric motor bogie of car spherical bearing of these requirements on the market.
The model utility content
The utility model provides a kind of linear electric motor bogie of car spherical bearing at the problems referred to above.
The technical solution of the utility model is: linear electric motor bogie of car spherical bearing, comprise overcoat and spherical bearing endosome, and described spherical bearing endosome comprises integrated interior cover, elastomer and mandrel, described elastomer is between interior cover and mandrel; Described mandrel is the cylindrical metal axle, comprises column structure and the middle spheric structure at two ends, and described elastomer is the rubber turn that is wrapped in mandrel spheric structure outside; Also be provided with two through holes on the column structure at described mandrel two ends.
The beneficial effects of the utility model are: the linear electric motor bogie of car is integral structure by interior cover, elastomer and mandrel hot briquetting with the endosome of spherical bearing, and described elastomer is the rubber with favorable elasticity; Spherical bearing endosome and overcoat are formed spherical bearing jointly.Spherical bearing not only bears radial load, also will carry certain axial action simultaneously.By the design of rubber profile, make spherical bearing in the radial load that bears, reach the requirement of product performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Linear electric motor bogie of car spherical bearing comprises overcoat 1 and spherical bearing endosome, and described spherical bearing endosome comprises integrated interior cover 2, elastomer 3 and mandrel 4, and described elastomer 3 is between interior cover 2 and mandrel 4; Described mandrel 4 is the cylindrical metal axle, comprises column structure and the middle spheric structure at two ends, and described elastomer 2 is for being wrapped in the rubber turn of mandrel 4 spheric structure outsides; Also be provided with two through holes 5 on the column structure at described mandrel 4 two ends.
