Background technology
Along with the Chinese Railway continuous advancement in technology, the speed-raising of the increment of load of railway truck becomes one of demand for development.China railways will progressively realize separating lines for passenger and freight, and more need development of new heavy duty, quick lorry, further improve freight-transport capacity.One of key of railway truck heavy duty, speed-raising is the structure and the performance of roller bearing adapter stabilizer bar.
At present, railway goods train bogie comprises several kinds of swing type bogie and axle box suspension type bogie trucks etc.The swing type bogie transversal dynamic performance is good, and vertical dynamic performance does not have clear superiority; Axle box suspension type steering framing wheel unsprung weight is light, and the rail vertical impact is firmly little with action, and vertical dynamic performance is good, and transversal dynamic performance does not have clear superiority.
In addition, also there is following deficiency in railway truck swing type bogie commonly used: when shaking seat and being bearing in tipper upset operating mode, when shaking the seat supporting and have rotary movement, have possibility of deviating from, its connection reliability, prevent deviating from performance and remain further raising; Because the dead lever fulcrum seat adopts welding manner usually with being connected of bogie truck, when the dead lever fulcrum seat is installed and keep in repair cutting, be prone to the parts body is caused damage, influence the bonded assembly reliability; Existing lever connection holder is designed to an independent part, is welded on during use on the railway goods train bogie, must carry out cutting operation separately during maintenance, and also easy body to parts causes damage.
Summary of the invention
The purpose of the utility model will provide a kind of axle box of railway wagon suspension swing type bogie exactly, the technical matters that lateral performance and vertical performance are difficult to improve simultaneously when solving vehicle operating, the connection reliability of raising bogie truck parts.
For realizing above-mentioned purpose; The utility model institute design-calculated axle box of railway wagon suspension swing type bogie comprises that wheel is to, axle box, bogie side frame, bolster, side bearing and foundation brake rigging; Be provided with adapter between said axle box and the bogie side frame; Below, said bolster two ends is provided with the central mounting device, and said bolster is provided with the dead lever fulcrum seat.Be provided with rubber spring between said bogie side frame and the adapter, the below of said bolster two ends central mounting device is connected with spring plank, and below, said spring plank two ends is provided with shakes seat, and the said seat that shakes links with bogie side frame through shaking the seat supporting.
Further, in order to limit the rotary movement that shakes the seat supporting, prevent accident, said support body back end outer surface of shaking the seat supporting is provided with the anticreep cylinder.As preferably; The horizontal length of the outstanding support body of said anticreep cylinder is 20～24mm; The width of said anticreep cylinder is 35～40mm, the vertical direction thickness≤20mm of said anticreep cylinder, and vertical direction symmetric line to the support body distance from bottom of said anticreep cylinder is 35～40mm.
Again further; In order to prevent that the dead lever fulcrum seat from installing and the parts body to be caused damage during the maintenance cutting; Fulcrum block body one side of said dead lever fulcrum seat is provided with the lever connection holder, and said fulcrum block body is provided with at least one riveted joint through hole.As preferably, said riveted joint connecting bore is three, is equicrural triangle and arranges.
The advantage of the utility model is: institute's design-calculated axle box of railway wagon suspension swing type bogie utilizes the low torsional stiffness of rubber spring through between bogie side frame and adapter, rubber spring being set, and discharges the swing of bogie side frame, pendulum point in the formation; The seat that shakes of below, spring plank two ends links with bogie side frame through shaking the seat supporting, forms bottom point, makes side frames do synchronous teeter with respect to bolster, has improved the lateral performance and the vertical performance of bogie truck, can satisfy the railway speed-raising truck demand.
Shake a back end outer surface that is bearing in support body and be provided with the anticreep cylinder.During installation, this anticreep cylinder is packed in the anticreep hole of relevant position on the truck side frame, can limit a rotary movement that shakes the seat supporting, can play the effect of preventing deviating from.
One side of fulcrum block body is provided with the lever connection holder; And be provided with the riveted joint through hole; Integral body has adopted riveted way to be connected with bogie truck, is easy to repair and replacement, and the body to parts in the time of can avoiding dead lever fulcrum seat and lever connection holder to install and keep in repair causes damage.Simultaneously, reduced number of spare parts, reduced the maintenance and management expense.
