Abstract
The utility model discloses a dustproof ring for a railway freight train bogie, and aims to provide a rubber dustproof ring, wherein the rubber dustproof ring is mounted in a swing bolster ring groove concentric with a top center plate on a freight train bogie; the top center plate and a bottom center plate are sealed by certain compression amount, so that sand and dust can be effectively from getting into and abnormal wear of the top center plate and the bottom center plate can be prevented. The dustproof ring comprises a rubber layer and is characterized in that U-shaped grooves are formed on one end face of the rubber layer and a semicircular groove is formed on the other end face of the rubber layer. The rigidity of the dustproof ring can be adjusted by the amount and the size of the U-shaped grooves. The utility model is mainly used as the dustproof ring on the railway fright train bogie.
Description
Technical field
The utility model relates to a kind of dust collar, more particularly, relates to a kind of railway freight car bogie dust collar.
Background technology
On the existing rail freight bogie of car, between body center plate and truck center plate, all there is not sealing dust-proof device, because cartridge is to be made by modified nylon materials, after sand and dust enter, can cause the abnormal wear between the upper and lower cartridge, influence the service life of cartridge, thereby influence the overall performance and the riding quality of vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of railway freight car bogie dust collar, be installed in truck vehicle bogie truck and the concentric bolster annular groove of body center plate, by certain amount of compression, make upper and lower cartridge realize sealing, can prevent effectively that sand and dust from entering, thereby prevent the abnormal wear of upper and lower cartridge.
For achieving the above object, technical solution of the present utility model is: a kind of railway freight car bogie dust collar, comprise rubber layer, it is characterized in that: an end face of described rubber layer 2 be provided with U-lag 1,1 ', the other end is provided with semi-circular groove 3.
The utility model is not compared with adopting dust collar at present, its advantage is: install dust collar in the concentric bolster annular groove of truck vehicle bogie truck and body center plate, by certain amount of compression, can make upper and lower cartridge realize sealing, can prevent effectively that sand and dust from entering between the upper and lower cartridge, thereby the abnormal wear about preventing, between cartridge prolongs service life of cartridge, improves the overall performance and the riding quality of vehicle.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1,1 '-U-lag, 2-rubber layer, 3-semi-circular groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises rubber layer, it is characterized in that: an end face of described rubber layer 2 be provided with U-lag 1,1 ', the other end is provided with semi-circular groove 3.
Its concrete implementation step is: the mould that will have U-lag 1,1 ' structure and semi-circular groove 3 structures is earlier closed, injecting rubber then in mould vulcanizes, make the rubber of injection form rubber layer 2, an end face of rubber layer 2 formation U-lag 1,1 after the depanning ', the other end forms semi-circular groove 3, the rigidity of dust collar can by U-lag 1,1 ' quantity and size adjust, for example: when amount of compression is 5mm, when pressure is 20KN, U-lag 1,1 ' quantity be 2 altogether, size all is 20 * 8mm (groove body * groove width).Dust collar of the present utility model is the rubber dust collar.
Claims (1)
