Abstract
The utility model discloses a secondary suspension device for a bogie of a rail engineering truck, which comprises a secondary rubber stack. The secondary rubber stack is a metal rubber vulcanized element formed by staggering six layers of steel plates and five layers of rubber plates; the lowest steel plates of the secondary rubber stack are provided with a cylindrical boss; after a platen is cushioned on the boss; the secondary rubber stack is fixed on a truck frame by a bolt; the top of the secondary rubber stack is connected with a sliding wearing plate, the friction coefficient of which is less than 0.1; the sliding wearing plate is contacted with a stainless steel plate; and the stainless steel plate is fixed on a truck body by a set screw. The problem that the steering resistance moment of the bogie relative to the truck body is large when the rail truck is passing through a small radius is effectively solved; and the steering stiffness of the bogie is greatly reduced; therefore, the digression danger of the bogie when passing through small radius is reduced.
Description
Technical field
The utility model relates to rail vehicle truck, especially the secondary suspension device of track engineering car bogie truck.
Background technology
Existing railway vehicle secondary suspension device adopt usually as shown in Figure 1 air bellow or helical steel springs as shown in Figure 2, also have low-speed truck locomotive secondary suspension to adopt as shown in Figure 3 rubber metal pad structure.
Thereby rail vehicle truck all is to rely on the bogie truck that is deformed into of secondary spring self to provide torsional stiffness to make guideway vehicle pass through curve smoothly when crossing minor radius, yet the lateral stiffness of secondary spring is subjected to the restriction of itself, when secondary spring adopts air bellow or steel spring, its lateral stiffness can be accomplished smaller, but air bellow complex structure, cost an arm and a leg, generally be used on metro bogie and the motor train unit bogie truck; Steel spring is subjected to the restriction in car load space to a great extent because vertical stiffness is little, generally is used on the express locomotive.The track engineering car is because the characteristics secondary suspension of this body structure should be selected the version of rubber metal pad for use.When secondary spring adopts the rubber metal pad form, its lateral stiffness will be bigger, and the lateral deformation by rubber metal pad provides the torsional stiffness of bogie truck can't satisfy the very designing requirement of small curve radius merely.
Summary of the invention
Technical problem to be solved in the utility model is, little at existing track engineering car turn radius, the characteristics that the secondary spring vertical misalignment is big, and provide a kind of track engineering car bogie truck secondary suspension device, it can solve guideway vehicle big problem of bogie truck relative car body steering resistance square when crossing minor radius effectively, reduce the gyro rigidity of bogie truck greatly, thereby reduce the danger that bogie truck derails when crossing minor radius.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of track engineering car bogie truck secondary suspension device comprises that two is rubber metal pad, this two is that rubber metal pad is by 6 layers of steel plate, 5 layers of metal-rubber sulfuration part that rubber plate is staggered to form, this two is that the foot steel plate of rubber metal pad is provided with cylindrical boss, after pad was established pressing plate on this boss, utilizing bolt was that rubber metal pad is fixed on the truck frame with two; This two is that the top attachment of rubber metal pad has friction coefficient less than 0.1 slip wearing plate, and this slip wearing plate contacts with stainless steel sheet, and this stainless steel sheet is fixed on the car body by holding screw.
Further improvement of the utility model is that the area of this stainless steel sheet is bigger than the area of slip wearing plate.
Further improvement of the utility model is that this stainless steel sheet is oval.
Further improvement of the utility model is also to be provided with lateral damper between this truck frame and the car body.
Compared with prior art, the beneficial effect that the utility model had is: the utility model is at leaning on the lateral deformation of rubber metal pad to provide the torsional stiffness of bogie truck can't satisfy the very deficiency of small curve radius at present merely, according to bogie truck two is the constructional feature of rubber metal pad, at the two slip wearing plates that have been the rubber metal pad top design, and this piece slip wearing plate friction coefficient is very little, usually less than 0.1, when vehicle moved on straight line, slip wearing plate and car body did not have relative motion; When vehicle passes through small curve radius, because this piece slip wearing plate friction coefficient is very little, a very little moment of gyration will make its relative car body slide, make bogie truck rotate a bigger angle relative to car body very like a cork, solved guideway vehicle big problem of bogie truck relative car body steering resistance square when crossing minor radius effectively, greatly reduce the gyro rigidity of bogie truck, thereby reduce the danger that bogie truck derails when crossing minor radius, make vehicle can pass through little curve safely.
Simultaneously, two is that the lateral stiffness and the vertical stiffness of rubber metal pad conditions each other, and generally two is that the design of rubber metal pad lateral stiffness will take into account dynamic performance and cross the ability of minimal curve radius.Adopt to make behind the utility model two to be that the rigidity Design of rubber metal pad becomes simply, two is that the rubber metal pad lateral stiffness will only consider that the vehicle dynamics performance gets final product.

The specific embodiment
With reference to Fig. 4-shown in Figure 8, the secondary suspension device of the utility model track engineering car bogie truck comprises that two is rubber metal pad 5, this two is that rubber metal pad 5 is by 6 layers of steel plate, 5 layers of metal-rubber sulfuration part that rubber plate is staggered to form, its foot steel plate has designed a cylinder boss 11, make two to be that rubber metal pad 5 can be located accurately and reliably, and its safety is improved.This two be rubber metal pad 5 to be installed to two of framework 12 by lower boss 11 be on the spring abutment 13, its mounting means is that pad is established pressing plate 7 on boss 11, utilizing M16 hexagonal bar iron 6 is that rubber metal pad 5 is fixed on the truck frame 12 safely with two.This two is that the top of rubber metal pad 5 is connected with slip wearing plate 3 by socket head cap screw 4, and this slip wearing plate 3 contacts with stainless steel sheet 2, and this stainless steel sheet 2 is fixed on the car body 15 by interior hexagonal flush end holding screw 1.This slip wearing plate 3 adopts High molecular material, and friction coefficient is very little, usually less than 0.1.When vehicle moved on straight line, slip wearing plate 3 did not have relative motion with car body 15; When vehicle passes through small curve radius, because slip wearing plate 3 friction coefficient are very little, a very little moment of gyration will make its relative stainless steel sheet 2 slide, and make truck frame 12 rotate a bigger angle relative to car body 15 very like a cork, thereby make vehicle safety pass through little curve.In order to compensate the abrasion of wheel 14, be to be provided with adjusting pad 8 under the foot steel plate of rubber metal pad 5 two.
Run out of stainless steel sheet 2 for slip wearing plate 3 relative stainless steel sheets 2 are not departed from when slide relative takes place, the area of stainless steel sheet 2 is bigger than the area of slip wearing plate 3.When angle of truck frame 12 relative car body 15 rotations, it mainly is along the vehicle operating direction that slip wearing plate 3 relative stainless steel sheets 2 slide, and therefore, the stainless steel sheet 2 that is installed on the car body 15 is designed to ellipse (with reference to figure 7).
In order to improve the horizontal riding quality of locomotive, also be provided with a lateral damper 9 on each truck frame 12, lateral damper 9 two ends connect truck frames 12 and car body 15(with reference to figure 8 by hexagonal bar iron 10).
