Abstract
The utility model relates to a transverse rubber stop for a motor train unit bogie. The stop is arranged on a car body bogie and comprises a rubber support and a cover plate, wherein the cover plate is clamped at the end part of the inner side of the rubber support; the rubber support comprises a central spindle, an outer jacket and single layer of rubber which are vulcanized into an integrated elastomer structure; and a taper-shaped rubber pile structure is adopted, and both the central spindle and the outer jacket are taper-shaped. The transverse rubber stop has simple and reasonable structure, good flexibility and great non-liner rigidity; the stop is contacted with a draw beam when the car body moves transversely for an over-long distance, while the stop needs rigid contact when the car body moves vertically for 45mm; and the non-liner rigidity is great, and the transverse rubber stop is relatively soft in the earlier stage and relatively rigid in the later stage, therefore the stop is contacted with the draw beam when the car body moves transversely for an over-long distance, and the stop plays flexible-supporting and limiting roles and prevents the car body from moving transversely for an over-long distance.
Description
Technical field
The utility model relates to a kind of rolling stock Rubber Parts, specifically, relates to a kind of motor train unit bogie truck Rubber Parts.
Background technology
Motor train unit are the present main high speed train of China, and for guaranteeing the operation stability and the stationarity of vehicle, one of motor train unit bogie truck is all to need a large amount of Rubber Parts that adopt with secondary suspension.Wherein, when the cross-car displacement is big, need to provide the Rubber Parts of sinking support and cross spacing between car body and the draw beam for it, but, at present domestic lack a kind of like this for the Rubber Parts of sinking support and cross spacing is provided between car body and the draw beam, improving vibration of vehicle performance and traveling comfort, and prevent the cross travel that car body is excessive.
The utility model content
The purpose of this utility model is to need spacing and sinking support at existing motor train unit car body when cross travel is big, and vibratility and traveling comfort, provide a kind of simple and reasonable, flexible good, non-linear rigidity big, motor train unit bogie truck with limit function is with horizontal rubber stop.
The technical solution of the utility model is: a kind of motor train unit bogie truck is with horizontal rubber stop, described stop is installed on the car body bogie truck, this stop comprises rubber plinth and cover plate, cover plate is connected to the end of rubber plinth inboard, described rubber plinth comprises mandrel, overcoat and individual layer rubber, mandrel, overcoat and the individual layer vulcanization of rubber are the elastomer structure of one, and adopt the cone rubber pile structure, and described mandrel and overcoat all are set to taper;
Preferably, described cover plate is connected to the end of overcoat inboard.
The beneficial effects of the utility model are: the utility model is simple and reasonable, flexibility good, non-linear rigidity is big, when the cross-car displacement is excessive, contact with draw beam, and car body is wanted the rigidity contact in vertical deviation 45mm, because its non-linear rigidity is big, early stage is comparatively soft, later stage rigidity is bigger, so, when the cross-car displacement is excessive, contact with draw beam, play sinking support and spacing effect, prevent the cross travel that car body is excessive.The utlity model has simultaneously laterally, the longitudinal rigidity transmission laterally, longitudinal force.

Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the A-A section-drawing of the utility model specific embodiment;
Fig. 3 is the B-B section-drawing of the utility model specific embodiment.
The specific embodiment
The specific embodiment of the present utility model is as follows: as shown in Figures 1 to 3, a kind of motor train unit bogie truck is with horizontal rubber stop, described stop is installed on the car body bogie truck, this stop comprises rubber plinth 1 and cover plate 2, cover plate 2 is connected to the end of rubber plinth 1 inboard, described rubber plinth 1 comprises mandrel 3, overcoat 4 and individual layer rubber 5, mandrel 3, overcoat 4 and 5 sulfurations of individual layer rubber are the elastomer structure of one, and adopt the cone rubber pile structure, described mandrel 3 and overcoat 4 all are set to taper; Cover plate 2 is connected to the end of overcoat 4 inboards.
During work, usage condition is: minimum temperature is-40 ℃, and highest temperature is 50 ℃, and relative humidity is 100%.Performance test is as follows:
(1) quiet stiffness test
Deflection under the vertical 1000kg is: 28mm
Deflection under the vertical 32000kg is: 45mm
(2) fatigue test
Fatigue test: 2000～3500kg radially, 2～5Hz, 2,000,000 times
Claims (2)
1. a motor train unit bogie truck is with horizontal rubber stop, it is characterized in that: described stop is installed on the car body bogie truck, this stop comprises rubber plinth and cover plate, cover plate is connected to the end of rubber plinth inboard, described rubber plinth comprises mandrel, overcoat and individual layer rubber, mandrel, overcoat and the individual layer vulcanization of rubber are the elastomer structure of one, and adopt the cone rubber pile structure, and described mandrel and overcoat all are set to taper.
