The utility model discloses a down reasonable, the properties of product stability of articulated mounting structural design, low in manufacturing cost, long service life. Adopt simultaneously nonmetally from the lubricating structure form, the noise is little, has improved life greatly, and is non -maintaining.
Description
Technical field
The utility model relates to articulated mounting under a kind of guideway vehicle, rises and connect and transmit most longitudinal force and transverse force between two joint compartments, and support passage floor and run-through channel for personnel by acting on.
Background technology
At present light rail, version hinged under subway primarily of bearing and foundry goods composition, its complex structure, parts are more, and cost is high, and bearing wear is serious, causes part stability that noise-reducing can be descended large.
The Hu Baila company substantially only having Germany that present international guideway vehicle articulated mounting is technically comparatively ripe, this company is apart from the modern development & production history having 60 years.This series products is technically also immature at home at present, and technological level is lower, and properties of product are poor, and the life-span is unstable, and productive costs is high.Structurally there is design not enough simultaneously, rotate dumb, the abrasion of motion process centre bearer produce abnormal sound, affect product stability energy.
Utility model content
Easily wear away to solve existing articulated mounting, easy generation noise, require the problem that car body ground clearance is higher, the utility model aims to provide articulated mounting under a kind of guideway vehicle, the anchor bearing of this lower articulated mounting adopts non-metal self-lubricating structure form, noise is little, greatly can improve service life, simultaneously Maintenance free.
To achieve these goals, the technical scheme that the utility model adopts is: articulated mounting under a kind of guideway vehicle, comprise the permanent seat for being fixedly linked with the first car body in adjacent two car bodies, for the bearing seat be fixedly linked with the first car body in adjacent two car bodies; Its constructional feature is, described bearing seat, built with self-lubricating bearing, is fixedly linked through the tween drive shaft of described self-lubricating bearing and described permanent seat.
Thus, connect two car bodies by self-lubricating bearing, have three-dimensional rotational freedom, can bear vertical force, transmit most longitudinal force and transverse force, high lubricating effect, noise is little, non-maintaining.
According to embodiment of the present utility model, can also do further to optimize to the utility model, the technical scheme below for being formed after optimization:
Preferably, the described self-lubricating bearing wearing layer that comprises outside race, bearing inner ring and be arranged between outside race and bearing inner ring; Described bearing inner ring is connected with described tween drive shaft interference fit, and outer wall and the bearing seat of described outside race are fixedly linked.
Further, the two ends of described self-lubricating bearing are respectively equipped with seal ring and lower seal, avoid self-lubricating bearing be subject to outside contamination and reduce lubricant effect.
As the version that a kind of concrete guarantee tween drive shaft and permanent seat are fixedly linked, described tween drive shaft is fixed on permanent seat by fastener, and on fastener, stop washer is housed.
Preferably, described permanent seat has rotation slot, two cell walls of this rotation slot all has the axis hole for installing tween drive shaft; The bearing support part that self-lubricating bearing is housed is placed in this rotation slot, and is placed in respectively in the axis hole of rotation slot cell wall through the two ends of the described tween drive shaft of self-lubricating bearing.Further, described permanent seat has Liang Ge ear, and each ear all has axis hole; Described rotation slot is formed between described Liang Ge ear.
Preferably, described guideway vehicle is city rail vehicle.
Preferably, described wearing layer is non-metallic wear resistant layer, and more preferably, described wearing layer is that the special engineering plastics of bearing are made, as being made up of such as polytetrafluoroethylplastic plastic.
Compared with prior art, the beneficial effects of the utility model are: bearing of the present utility model adopts the mode of non-metal lubrication, without the need to apply lubrication oil in use procedure, non-maintaining; Structure is simple, is particularly suitable for coordinating using without the need to the liftoff low city rail vehicle of platform.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of a kind of embodiment of the utility model;
Fig. 2 is the A--A cutaway view of Fig. 1.
In the drawings
1-permanent seat; 2-bearing seat; 3-tween drive shaft; 4 bearing inner rings; The upper seal ring of 5-; 6-lower seal; 7-outside race; 8-circular nut; 9-stop washer; 10-wearing layer.
Detailed description of the invention
Articulated mounting under a kind of city rail vehicle, as shown in Figure 1 and Figure 2, comprise permanent seat 1, bearing seat 2, permanent seat 1 is connected with two car bodies by binding bolt group respectively with bearing seat 2, described permanent seat 1, bearing seat 2 is connected with tween drive shaft by self-lubricating bearing, wherein in self-lubricating bearing embedded axle bearing 2, then be connected with permanent seat 1 through bearing center hole by tween drive shaft 3, and add that circular nut stop washer 9 and circular nut 8 are by fastening for tween drive shaft 3.
Self-lubricating bearing is made up of outside race 7, bearing inner ring 4 and self-lubricating bearing wearing layer 10, and self-lubricating bearing wearing layer, between outside race 7 and bearing inner ring 4, is close on outside race 7 inwall.Close circular nut end is lower seal 6, otherwise is upper seal ring 5.
Thus, permanent seat adds circular nut stop washer with bearing seat by self-lubricating bearing and tween drive shaft, circular nut is connected after coordinating, and the upper and lower two ends of bearing add lower seal composition under articulated mounting.Lower articulated mounting of the present utility model is installed on the bottom end rail of car body, as the lower hinge of hinged car body.
The utility model has carried out optimal design in lower hinging integral structure, and structure is simple, and good stability is non-maintaining, can meet the large load of city rail vehicle, and track route radius of curve is little waits requirement, portable construction, installs simple.Simplified processing process process, reduces productive costs.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen into the application's claims limited range.
