Abstract
The utility model provides a special railway lorry side bearer, which relates to the technical field of special railway lorries. The special railway lorry side bearer comprises a side bearer box, an elastic side bearer body, a roller and a side bearer wear plate, wherein the bottom of the roller supports the bottom of the side bearer box; both sides of the roller are respectively provided with elastic elements; and one end of the elastic elements supports the roller, and the other end is connected with the side bearer body. When the special railway lorry is running, the elastic side bearer body and the side bearer wear plate combine for action, the turning drag torque can be enlarged, and the running speed of the special railway lorry can be improved. When the acting force of the whole side bearer in the vertical direction is overlarge, an upper side bearer wear plate acts on the roller, the roller rolls under the action of the elastic elements of both sides of the roller, the turning drag torque in the moment can be effectively reduced, the curve passing capability of the special railway lorry is further improved, the acting force born by the roller in the vertical direction is directly transferred onto a box body of the side bearer box, and the bearing capability in the vertical direction is large.
Description
Technical field
The utility model relates to the extraordinary lorry technical field of railway, relates in particular to the extraordinary lorry side bearing of a kind of railway.
Background technology
The extraordinary lorry of railway generally comprises parts such as carrier, great underframe, little underframe, bogie truck, brake equipment, coupler and draft gear.Wherein, little underframe is bearing on the railroad track by bogie truck, and great underframe is bearing on two little underframe; Carrier two outer ends are bearing in respectively on two great underframes, and the effect of bogie truck is a supporting body, and guided vehicle is along rail running, and bear the various load from car body and circuit.Between great underframe and the little underframe, all link into an integrated entity by cartridge and side bearing between little underframe and the bogie truck, cartridge is arranged on the middle part, mainly bears vertical load; Side bearing is arranged on the cartridge both sides, when car body generation side-sway, plays support, stabilization, prevents that car body side-sway angle is excessive.
Side bearing mainly contains two kinds: a kind of is gap (rigidity) side bearing, can prevent that car body side-sway angle is excessive; Another kind is an elastic side bearing, not only can play to prevent the excessive effect of car body side-sway angle, also can increase between great underframe and the little underframe or the steering resistance square between little underframe and the bogie truck, so that improve the running velocity of vehicle.At present, between extraordinary lorry great underframe of domestic and international most of speed rail and the little underframe and all adopt elastic side bearing between little underframe and the bogie truck, below this is carried out brief description.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of representative type elastic side bearing in the prior art.
Elastic side bearing shown in Figure 1 is a kind of JC type double-acting elastic side bearing (hereinafter to be referred as side bearing), comprises parts such as elastic side bearing body 101, roller 102, roller bearing 103, side bearing wear plate 104, side bearing 105, side bearing box 106.Side bearing 105 is arranged in the side bearing box 106, the bottom of elastic side bearing body 101 is embedded in the side bearing 105, the top of elastic side bearing body 101 is provided with the side bearing wear plate 104 with certain friction coefficient, the side of elastic side bearing body 101 is provided with roller bearing 103 side by side, roller 102 is sleeved on the roller bearing 103, and can rotate flexibly.
Wherein, elastic side bearing body 101 provides vertical application force; Side bearing wear plate 104 by with the effect of body side bearing wearing plate 107, so that suitable friction coefficient to be provided; Elastic side bearing body 101, side bearing wear plate 104 The combined effects can increase the steering resistance square, improve the running velocity of vehicle; Roller 102 can prevent that the vehicle body swing angle is excessive, and simultaneously, when whole side bearing vertical direction application force was excessive, roller 102 can effectively reduce the steering resistance square in this moment by roll (friction coefficient is 0.1), to improve the curve negotiation ability of vehicle; Side bearing 105, roller bearing 103 are contained in the side bearing box 106, are respectively elastic side bearing body 101, roller 102 provides supporting.
The side bearing of this structure by choosing suitable steering resistance square, had both suitably increased the steering resistance square of vehicle, had prevented that again the steering resistance square is excessive; In other words, both can improve the running velocity of vehicle, can improve the curve negotiation ability of vehicle again.The side bearing of this structure is more reasonable because of design, at present a large amount of entruckings uses on the extraordinary lorry of China railways.
But, in the side bearing of this structure, the application force of the vertical direction that roller 102 is subjected to is delivered to through roller bearing 103 on the box body of side bearing box 106, because the load-carrying capacity of roller bearing 103 is less, easily be pressed down, thereby cause whole side bearing to be damaged, side bearing can not satisfy the requirement of the normal operation of vehicle, particularly the railway Heavy Duty Freight Car need be born bigger load, as adopting this structure side bearing, side bearing will very easily be damaged, and have a strong impact on the normal operation of the extraordinary lorry of railway.
