Description
Technical field
The utility model relates to a kind of passenger door of bus, but specifically relates to the mark time passenger door new construction on floor of a kind of adaptive zone gradient.
Background technology
At present; The connection mode of general-duty bus passenger door and bus body is as shown in Figure 1: door-hinge permanent seat 103 passes through screw retention on the bus body floor; Door pivot assembly 101 is packed into from door-hinge permanent seat upper end; Plain radial bearing 104 endoporus that make the axle 102 of having strong market potential of door-hinge permanent seat penetrate door-hinge assembly 101, again with passenger door door leaf 106 be welded on door pivot up and down the swing arm 105 at two ends link together.Hairbrush 107 is fixed on the fixed mount of door leaf lower profile realizes sealing function.
Said structure is simple and reliable, but has weak point: at first, the connection structure of this kind door pivot and base requires base must be horizontally fixed on the body platform; When vehicle body mark time the floor when having the gradient this connection structure can't be suitable for: bus newly developed recently adopts the band gradient structure of marking time more; The ponding corrosion that prevents to mark time, when traditional passenger door structure is used for this type passenger vehicle, in the middle of the process of opening the door after door leaf is opened to certain angle; Scratching takes place in meeting of door leaf lower edge and the floor of marking time that has a gradient; Door leaf and floor scratching cause the passenger door can't complete opening, owing to can cause the damage of door leaf and floor.Secondly; This door-hinge permanent seat and door-hinge are through plain radial bearing bonded assembly form; Can only the limiting door diameter of axle to degree of freedom, the degree of freedom axial to door-hinge can't limit, like this in the bus driving process since vehicle body pitch and will cause door pivot, passenger door door leaf bob; Not only form big noise, and because the long-term vibration of mechanism causes parts to reduce service life.And under such service conditions, plain radial bearing bears bigger axial force and impact load for a long time, is easy to cause bearing failure.
Summary of the invention
Be not suitable for band gradient body platform and door leaf is beated, noise is bigger problem in order to solve traditional passenger door structure, the utility model provides a kind of door leaf that can guarantee not beat, and can adapt to the mechanism of the different body platform gradients again.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The mark time bus passenger door on floor of a kind of adaptive zone gradient; It comprises and is fixed on passenger vehicle mark time door-hinge fixed base plate and door-hinge lower end on the floor; Door-hinge lower end overcoat door pivot steel pipe, door pivot steel pipe also weld with swing arm, and the other end of swing arm connects door leaf; Described door-hinge fixed base plate connects ejector rob axis, and the top of ejector rob axis is arranged in the door-hinge hole of door-hinge lower end; The anti-device of beating is set between described ejector rob axis and door-hinge lower end; And fixing rotary seal plate mechanism on the door leaf lower sectional material of said door leaf bottom.
The described anti-device of beating comprises the alignment pin that is arranged on the ejector rob axis top and is arranged on the radially locating bush of both sides of ejector rob axis top that locating bush is fastening with jam nut.
The top of said ejector rob axis is spherical, the semicircle concave spherical surface of the inside face of locating bush for matching with the Ball-form Crown Bar ln A axle.
Described locating bush is the nylon locating bush.
Lower end at jam nut is provided with circlip for bore.
Rotary seal plate mechanism by rotary seal profile material, sealing joint strip and fixedly nylon sheet constitute.
Adopt the utility model of technique scheme; Compare with conventional confguration and can effectively eliminate the bob of bus passenger door door pivot in the vehicle ' process; And solved because the noise that the door pivot bob is brought, prevented that parts such as bus passenger door door leaf are because the long-term bob of door pivot causes reduce and damage of components service life.In addition, the door-hinge bed plate of the utility model can have an angle with horizontal direction, can adapt to multiple body platform with a slope.
Description of drawings
Fig. 1 is the prior art constructions scheme drawing.
Fig. 2 is the close the door structural representation of state of the utility model.
Fig. 3 is the structural representation of the utility model door opening state.
The specific embodiment
Like Fig. 2, shown in Figure 3; The utility model comprises and is fixed on passenger vehicle mark time door-hinge fixed base plate 8 and door-hinge lower end 2 on the floor; Door-hinge lower end 2 overcoat door pivot steel pipes 1; Wherein door pivot steel pipe 1 also with swing arm 10 welding, the other end of swing arm 10 is connected through the oscillating bearing in the fixed support that is welded on bearing pin and door leaf 12 bottoms in the swing arm 10, plays the fixedly effect of door leaf 12.
In the utility model, door-hinge fixed base plate 8 tops connect ejector rob axis 4, and the top of ejector rob axis 4 is arranged in the door-hinge hole of door-hinge lower end 2; The anti-device of beating is set between ejector rob axis 4 and door-hinge lower end 2, and the anti-device of beating comprises the alignment pin 3 that is arranged on ejector rob axis 4 tops and is arranged on the radially locating bush 5 of both sides of ejector rob axis 4 tops that it is preferred forms that locating bush 5 adopts the nylon locating bushs; Wherein, the door-hinge hole interference fit of alignment pin 3 and door-hinge lower end, locating bush 5 usefulness jam nuts 6 are fastening, can effectively prevent door pivot and door leaf 12 bobs like this.
Beat for preventing better, the top of ejector rob axis 4 is spherical, and the semicircle concave spherical surface of the inside face of locating bush 5 for matching with the Ball-form Crown Bar ln A axle is provided with circlip for bore 7 in the lower end of jam nut 6.Like this; Five degree of freedom of ejector rob axis 4 have been limited through the effect of cooperatively interacting of alignment pin 3, nylon locating bush 5, jam nut 6, circlip for bore 7; Ejector rob axis 4 only can be around the rotation of Z axle, and when door leaf 12 opened and closed, door pivot and ejector rob axis were fixed angle and rotate; Door-hinge fixed base plate 8 can be fixing arbitrarily in an angular range like this, thus the acclive body platform of adaptive zone.
When in addition, fixing rotary seal plate mechanism on the door leaf lower sectional material 11 of door leaf 12 bottoms, rotary seal plate mechanism are used for eliminating door leaf 12 and open with the interference on band gradient floor.Rotary seal plate mechanism by rotary seal profile material 13, sealing joint strip 14 and fixedly nylon sheet constitute.
The fitting process of the utility model is: at first alignment pin 3 is packed under the door-hinge in the stomidium; Nylon locating bush 5 is inserted in from ejector rob axis 4 lower ends respectively with jam nut 6; Nylon locating bush 5 interior semi-circular concave spherical surfaces and ejector rob axis 4 spheres are fitted; And in the door-hinge hole of packing into; Jam nut 6 and door-hinge lower end negative thread are tightened, guaranteed the reliable contact of alignment pin 3, ejector rob axis 4, nylon locating bush 5; The circlip for bore 7 of packing into prevents that jam nut from becoming flexible; Door-hinge fixed base plate 8 and ejector rob axis 4 are tightened; Jackscrew 9 is tightened, fixed door-hinge.
The working process of the utility model is: when passenger door was opened, door pivot drove door leaf 12 and rotates, and swing arm 10 contacts with rotary seal profile material 13, and rotary seal profile material 13 turns an angle, and realized the passenger door unlatching.Because rotary seal profile material 13 rotated certain angle in the middle of the process of opening the door, the certain altitude that risen simultaneously, therefore after door leaf is opened not can with the floor scratching of marking time with a slope; When passenger door was closed, rotary seal profile material 13 resetted under the effect of the torsion spring of S. A. place installation, breaks away from swing arm, and under the application force of doorframe limit adhesive tape, sealed gap down, realized positiver sealing.
