Abstract
The utility model relates to an elastic normal contact lower side support for a railway vehicle. The utility model comprises a lower side support body, an adjusting liner plate, and a lower side support box. The utility model is characterized in that the inner part of the lower side support box is provided with two elastic spacing gears and circular springs. The lower side support body is supported on the two circular springs. A friction plate is arranged on the lower side support body, and the frond and the back ends of the lower side support body are provided with wearing plates. Smaller gaps are formed between the wearing plates and the lower side support box. The utility model can cause a bogie truck to have stable swing friction moment, and to better limit the rolling of the vehicle. Therefore, the critical speed and the running stability can be improved. The utility model is suitable for accelerating railroad freight cars.
Description
The utility model relates to a kind of railway vehicle with the normal contact bottom side bearing of elasticity; Belong to railway transport vehicle accessory class.
At present, existing rail freight side bearing is generally clearance-type, a small amount of flexible normal contact, when the clearance-type side bearing is in straight way and less rolling at vehicle, have the gap between the body side bearing of car body and the bottom side bearing of bogie truck, the friction that can not get between upper and lower side bearing of crawling that this moment, bogie truck produced suppresses, therefore, the critical speed of vehicle is low, and running stability is poor; And the normal contact side bearing of present elasticity has rubber block formula and steel circle spring formula; Its rubber elastic side bearing is because structure is limit, and pre compressed magnitude is little, and after the side bearing abrasion changed, the change in friction force that provides was very big, and stability is poor.Though and steel circle spring elastic side bearing has big pre compressed magnitude, its anti-poor performance of sidewindering.
The purpose of this utility model is to provide a kind of can provide essential, stable bogie truck revolution friction moment, and the normal contact bottom side bearing of elasticity that again can fine opposing car body sidewinders is to improve vehicle critical speed and running stability.
The technical solution of the utility model: this bottom side bearing is to comprise bottom side bearing body, adjustment backing plate and bottom side bearing box, it is characterized in that being provided with in the bottom side bearing box, the spacing shelves of two elasticity and two steel coil component springs, the spacing shelves of its elasticity and coil component springs place and adjust on the backing plate, it is peripheral that coil component spring is sleeved on the spacing shelves of elasticity, the spacing shelves of elasticity are to be combined by steel part and Rubber Parts sulfuration, the bottom side bearing body is bearing on two coil component springs, be provided with suitable friction coefficient and abrasion resistant friction plate above the bottom side bearing body, friction plate is by having suitable friction coefficient and the abrasion resistant material is made.In the front and back end of bottom side bearing body the abrasion resistant wearing plate is housed, wearing plate places between bottom side bearing body and the bottom side bearing box inboard, and closely connected bottom side bearing body has appropriate gap with the bottom side bearing box.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, this bottom side bearing is by bottom side bearing body 1, two steel coil component springs 2, two spacing shelves 3 of elasticity, friction plate 4, wearing plate 5, adjust backing plate 6 and bottom side bearing box 7 compositions, be provided with one in its bottom side bearing box and adjust backing plate 6 and 3 and two steel coil component springs 2 of two spacing shelves of elasticity, be that spacing shelves 3 of elasticity and steel coil component spring 2 are arranged on the adjustment backing plate 6, the spacing shelves 3 of steel coil component spring 2 and elasticity are sleeved on together, bottom side bearing body 1 is bearing on two steel coil component springs 2, be provided with a suitable friction coefficient and abrasion resistant friction plate 4 above the bottom side bearing body 1, be provided with abrasion resistant wearing plate 5 in the front and back end of bottom side bearing body 1, wearing plate 5 is closely connected on bottom side bearing body 1, and has appropriate gap between bottom side bearing box 7 inboards.
The bottom side bearing body 1 that friction plate 4 is housed is held up by spring 2 elasticity, when car body falls car, spring 2 can produce bigger pre compressed magnitude, the side bearing supporting power of Chan Shenging therefrom, this supporting power is big because of the pre compressed magnitude of spring 2, it is little to be subjected to production tolerance and side bearing friction plate 4 to wear away the variation that influences generation, thereby more stable friction force is provided.After spring 2 falls the car precompressed compression, still leave necessary gap between the spacing shelves 3 of bottom side bearing body 1 and elasticity, be beneficial to vehicle by the distortion circuit.The spacing shelves 3 of elasticity are to be combined by the steel part and the vulcanization of rubber, and when vehicle produced rolling, the spacing shelves 3 of elasticity had big rigidity, are then limited and sidewinder.Wearing plate 5 usefulness high-abrasive materials are made, but the long period keeps having only less clearance between body side bearing body 1 and the bottom side bearing box 7.
In sum, the utility model is a kind ofly can provide stable bogie truck revolution friction moment, can limit the normal contact bottom side bearing of elasticity that vehicle sidewinders again, thereby improve the critical speed and the traveling comfort of vehicle.Being fit to China railways speed-raising lorry uses.
