Description
Technical field
The utility model relates to the Vehicle Engineering technical field, relates in particular to a kind of elastic side bearing.Simultaneously, also relate to a kind of railway truck that is used for the elastic bolster guide plate of this elastic side bearing and adopts above-mentioned elastic side bearing.
Background technology
Railway truck generally comprises car body, bogie truck, brake equipment, coupler and draft gear etc. and partly forms.Wherein, the effect of bogie truck is a supporting body, and guided vehicle is along rail running, and bears the various load from car body and circuit.Car body and bogie truck link into an integrated entity by cartridge and side bearing.Cartridge is mainly born vertical load; Side bearing mainly contains two kinds, and a kind of is gap (rigidity) side bearing, and another kind is an elastic side bearing, and gap side bearing role mainly is to prevent that car body side-sway angle is excessive; Elastic side bearing also has and prevents the excessive effect of car body side-sway angle, has also increased the steering resistance square between car body and bogie truck simultaneously, can improve the running velocity of vehicle, and most of both at home and abroad at present roller bearing adapter stabilizer bar fast all adopts elastic side bearing.
Be illustrated in figure 1 as JC type elastic side bearing in the prior art, this elastic side bearing is located in the side bearing box 11, comprises side bearing 12 and the elastic side bearing body 13 of being located at the side bearing inner chamber, and the top of elastic side bearing body 13 is provided with side bearing wear plate 15 and body side bearing wearing plate 16 successively.
Wherein, elastic side bearing body 13 is mainly formed by rubber and metallic material sulfuration, comprise top board 131, side plate 133 and base plate 134 that metallic material is made, also comprise the elastic body 132 that elastomeric material forms, and the side rubber 135 between side plate 133 and top board 131.Side plate 133 is installed in the groove of side bearing 12, to determine the relative position of elastic side bearing body 13 and side bearing 12.
When railway truck moves on the straight line circuit, elastic side bearing body 13 can produce vertical (vertical direction as shown in Figure 1) application force because certain precompressed compression is arranged, and side bearing wear plate 15 provides suitable friction coefficient, the The combined effect increases the steering resistance square, improves the running velocity of vehicle.
Railway truck operates on the curve circuit, and when vehicle sidewindered, body side bearing wearing plate 16 contacted with roller, and the vertical force that this moment, elastic body 132 provided is a fixed value, and remaining vertical force is born by roller.When the vertical application force that is subjected to when elastic side bearing was excessive, roller can effectively reduce the steering resistance square by rotating (friction coefficient is 0.1), improves the curve negotiation ability of vehicle.
Be not difficult to find out that from the principle of work of above-mentioned elastic side bearing the mode of motion of elastic side bearing body 13 has two kinds: catenary motion and longitudinal movement (this paper's vertically is direction consistent with the car length direction in horizontal surface).Wherein, body side bearing wearing plate 16 has catenary motion over against side bearing 12, side plate 133 has vertical precompressed compression with side bearing 12, and side plate 133 does not have the catenary motion of relative side bearing 12, have relative perpendicular movement between side plate 133 and the body side bearing wearing plate 16, the shear deformation by side rubber 135 realizes.Therefore, tear between side plate 133 and the side rubber 135, occur cracking phenomena easily after long-time the use, influence the service life of elastic side bearing.
And because side rubber 135 is subjected to vertical shearing, when elastic body 132 vertical distortion were big more, the shear deformation that side rubber 135 is subjected to was big more.But in order to guarantee the reliability of side rubber 135, the stroke of elastic body 132 can not be too big, therefore, causes the stability of elastic side bearing not high.In addition, as seen from Figure 1, be free-running fit between side bearing box 11 and the side bearing 12, be that elastic side bearing is the location, gap in vertical (horizontal surface direction shown in Figure 1), this gap makes the steering resistance square of vehicle be subjected to certain loss, and bigger to the vehicle dynamics performance impact, reliability is not high.
At the problems referred to above, Chinese patent ZL200920170254.2 discloses a kind of railway truck and elastic side bearing thereof.As shown in Figure 2, its disclosed elastic side bearing comprises side bearing 2 and the elastic side bearing body 3 that is arranged in the side bearing inner chamber, the two side relative at side bearing is provided with groove, and side wear plate 1 is installed in the groove, and the side wear plate cooperates with the rigid panel roof pressure of elastic side bearing body.In use, side wear plate and elastic side bearing body rub, and making can not provide enough precompressed compressions by the rapid attenuate of side wear plate, and the replacing side wear plate that this will be regular causes railway truck to need frequent maintenance.
Therefore, how improving the reliability of elastic side bearing of railway wagon, improve the service life of elastic side bearing, and then improve the dynamic performance of railway truck, is the present technical issues that need to address of those skilled in the art.
