Abstract
The utility model relates to a vertical elastic pull rod device used for a railway freight car bogie; the device comprises elastic ball sleeves, a pull rod, a pin axle, an adjusting gasket, a positioning sleeve, a locking nut and mounting seats, and the mounting seats are respectively cast on the axle box and the swing bolster of a bogie; mounting holes are arranged at the both ends of the pull rod, and the elastic rubber ball sleeves are installed in the mounting holes at the both ends of the pull rod; the pull rod is connected with the mounting seats on the axle box and the swing bolster through the pin axle, the adjusting gasket, the positioning sleeve and the locking nut. Four groups of vertical elastic pull rod devices are installed on each bogie, and the vertical elastic pull rod device can improve the vertical positioning rigidity of the axle box of the bogie. The vertical elastic pull rod device provides proper axle box elastic positioning rigidity, avoids the destabilization of the snaking motion of the vehicle which is easy to happen within the running speed range, ensures the vehicle to have good guiding performance when running on a curve, and reduces the abrasion of the wheel edge to the steel rail; through mounting the device, the power performance of the vehicle can be effectively improved, the running quality of the vehicle can be enhanced, and the maintenance cost of the vehicle can be reduced.
Description
Technical field
The utility model relates to a kind of railway goods train bogie longitudinal elasticity pull rod device, belongs to a kind of accessory of rolling stock.
Background technology
At present, the rubber spring location is adopted in the axle box of axle box suspension swing type railway freight car bogie location, is provided with rubber spring between framework and the axle box, because the rubber spring vertical stiffness is smaller, vertical, horizontal requires suitable rigidity to realize the elasticity location again.The longitudinal rigidity that rubber spring provides is less than the desired axle box longitudinal register of bogie truck rigidity, and the serpentine locomotion unstability takes place in operational speed range vehicle easily.
Summary of the invention
The purpose of this utility model is the axle box longitudinal register rigidity problem less than normal at axle box suspension swing type railway freight car bogie, provide a kind of simple in structure, economical and practical, can improve axle box longitudinal register rigidity and the stable longitudinal elasticity pull rod device of bogie truck.
The technical solution of the utility model is: railway goods train bogie is to comprise elastic caoutchouc ball cover, longitudinal tie, bearing pin and adjusting disk, locating bush, jam nut and mount pad with the longitudinal elasticity pull rod device, and its mount pad is separately positioned on the axle box and bolster of bogie truck; Have mounting hole at the longitudinal tie two ends, its elastic caoutchouc ball cover is arranged in the mounting hole at longitudinal tie two ends; Longitudinal tie, by bearing pin, adjusting disk, locating bush and jam nut and axle box are connected with mount pad on the bolster.Mount pad is cast in respectively on axle box and the bolster.Elasticity longitudinal tie device connects with mount pad on axle box and the bolster by bearing pin.Each bogie truck is installed quadruplet longitudinal elasticity pull rod device, and elasticity longitudinal tie Design of device can satisfy axle box longitudinal register rigidity and the transmitted load that improves bogie truck.
This longitudinal elasticity pull rod device provides suitable axle box elasticity locating stiffness, not only can avoid vehicle that the serpentine locomotion unstability takes place in operational speed range easily, can also guarantee to have good steering capability when vehicle moves on curve, alleviate the abrasion of wheel rim and rail.Thereby improve the vehicle dynamics performance, improve the riding quality of vehicle, reduce the vehicle maintenance cost, satisfied railway development heavy duty, the needs of lorry fast, have good social benefit and economic benefit.And this device has from heavy and light, and characteristics such as convenient manufacturing, maintenance are suitable for and apply, and satisfy railway truck heavy duty and fast-developing requirement.
