Abstract
The utility model relates to a double function elastic roller side bearing used for a railway wagon bogie, particularly rapid and heavy-duty wagons. The side bearing is composed of a sulfurized integral rubber-metal composite spring, an abrasion-proof synthesized side bearing plate, a roller, a side bearing socket, bolts, etc., wherein, the rubber-metal composite spring and the roller are arranged in parallel, and the rubber-metal composite spring adopts the integral structure sulfurized by a steel spring, rubber, a steel plate, etc. The utility model overcomes the drawback of present steel sliding side bearings, increases the snaking motion critical speed of railway wagons under light-duty or empty condition, and reduces the wheel track abrasion in curve negotiating. According to different automobile parameters, the utility model can change different abrasion-proof synthesized side bearing plates with different friction coefficients to realize the reasonable matching of side bearing parameters and to prolong the endurance life of the utility model.
Description
The utility model is to be adapted to railway goods train bogie, particularly fast and the rubber-metal composite elastic side bearing of heavy-duty freight car bogie truck use.
What the roller bearing adapter stabilizer bar of the existing cartridge carrying of China adopted is contactless rigid plane slip side bearing, and car body is vertical, horizontal and vertical load by central cartridge transmission.When vehicle moved on straight line, common upper and lower side bearing face did not contact, and has certain clearance, had only when body oscillating causes that strongly the car body angle of roll is excessive, and upper and lower side bearing just is in contact with one another to stop car body further to tilt.When vehicle passed through curve, upper and lower side bearing often contacted, and produced the cliding friction moment of gyration between car body and bogie truck.The shortcoming of existing this rigidity slip side bearing mainly contains three aspects: (1) is on straight line or curve, when car body exists unbalance loading or circuit to have distortion, four side bearings of same car have the contact of part side bearing, at this moment the part of the vertical load of car body will be transferred to the side bearing place of contact, thereby cause that this steering framing wheel takes turns right increase and decrease and carry left and right, jeopardize traffic safety.(2) particularly empty wagons hunting critical speed is generally on the low side for vehicle, influences the raising of running velocity.(3) after upper and lower rigidity slip side bearing contact, cause the excessive cliding friction steering resistance square between bogie truck and the car body, this steering resistance square will reduce the curving performance of vehicle, increase the abrasion of wheel rim and rail.In order to improve the shortcoming of existing rigidity slip side bearing, once on roller bearing adapter stabilizer bar, adopted the roller side bearing abroad, though the roller side bearing can reduce the bogie truck that causes owing to cliding friction and the excessive cliding friction steering resistance square between the car body.But after running velocity improved, this side bearing can not actv. control vehicle hunting.
The purpose of this utility model is the double-acting elastic roller side bearing that will provide a kind of elasticity precompressed compression side bearing and roller side bearing to combine, it can improve rail freight, the particularly critical speed of crawling of vehicle, the hunting of control vehicle effectively under complete vehicle curb condition.When being limited in railway vehicle simultaneously, turn round the further increase of friction moment between car body and the bogie truck, improve the curving performance of vehicle by curve.
The purpose of this utility model is achieved in that rubber-metal complex spring (1) and roller (3) is placed on the side bearing base (4) side by side, adopt steel spring (6), rubber (7) and steel plate (8) sulfuration integrative-structure as elastic supporting element, improve the gyro rigidity between bogie truck and the car body, thereby improve the critical speed of crawling of bogie truck.When complex spring (1) work was out of shape greater than D, roller (3) worked, and the further increase of restriction side bearing friction force improves the bogie truck curve negotiation ability.Embed wear-resisting synthetic material (2) at the top of complex spring (1), improve the wear resisting property of side bearing, reduce the abrasion of car body body side bearing, can embed the wear-resisting synthetic material (2) of different coefficients of friction according to different vehicle parameters simultaneously.
The utility model is because the structure that has adopted complex spring (1) and roller (3) to place side by side, makes it have and improves crawl critical speed and improve the double action of curve passing through through performance of rail freight simultaneously.At the running velocity that improves vehicle, the aspects such as abrasion that reduce wheel and rail have obvious superiority.
Fig. 1 is the front section view of double-acting elastic roller side bearing.
Fig. 2 is the birds-eye view of double-acting elastic roller side bearing.
Below in conjunction with Fig. 1 and Fig. 2, narrate embodiment of the present utility model: the utility model is by steel spring (6), rubber (7) and steel plate (8) sulfuration all-in-one-piece rubber-metal complex spring (1), wear-resisting synthetic material (2), roller (3), side bearing base (4) and screw compositions such as (5), rubber-metal complex spring (1) is connected on the side bearing base (4) by screw (5), embed wear-resisting synthetic material (2) at the top of rubber-metal complex spring (1), roller (3) is located in the side bearing box of side bearing base (4), and direction roller (3) can freely move in the side bearing box all around.During initial the installation, complex spring (1) is by precompressed compression, and when vehicle operating, complex spring (1) and roller (3) work.When changing original side bearing, only original side bearing need be taken out from bogie truck bottom side bearing box, the utility model is put into the bottom side bearing box,, determine the height of side bearing backing plate simultaneously according to upper and lower side bearing clearance with the utility model.
Claims (3)
1. one kind is applicable to fast and the double-acting elastic roller side bearing of heavy-duty freight car bogie truck, is made up of rubber spring or steel spring, it is characterized in that rubber-metal complex spring (1) and roller (3) are placed on the side bearing base (4) side by side.
2. side bearing according to claim 1 is characterized in that rubber-metal complex spring (1) adopts steel spring (6) rubber (7) and steel plate (8) sulfuration integrative-structure.
3. side bearing according to claim 1 is characterized in that embedding wear-resisting synthetic material (2) at the top of rubber-metal complex spring (1).
