Изобретение относитс к железнодорожному транспорту, в частности к рессорному подвешиванию локомотива.The invention relates to railway transport, in particular to a spring suspension of a locomotive.

Известно рессорное подвешивание рельсового транспортного средства, содержащее листовые рессоры, опирающиес на буксы колесных пар, продольный балансир, средней частью св занный с рамой тележки, и вертикальные подвески с головками, соедин ющие смежные концы листовых рессор с концами балансира 1.A suspension suspension of a rail vehicle is known, comprising leaf springs supported on wheel axle boxes, a longitudinal balance bar associated with the bogie frame with a middle part, and vertical suspensions with heads connecting adjacent ends of the leaf springs with the ends of the balance bar 1.

Недостатком известного рессорного подвещивани вл етс низка чувствительность подвешивани , что ведет к ухудшению ходовых качеств транспортных средств.A disadvantage of the known spring illumination is the low sensitivity of the suspension, which leads to a degradation of the driving characteristics of vehicles.

Цель изобретени - улучшение ходовых качеств транспортного средства.The purpose of the invention is to improve the ride quality of the vehicle.

Поставленна цель достигаетс тем, что рессорное подвешивание рельсового транспортного средства, снабжено кронштейном, жестко закрепленным на раме тележки, а между продольным балансиром и кронштейном размец1ены последовательно упругие элементы и подвижна опора с вогнутой криволинейной поверхностью, взаимодействующей с верхней поверхностью балансира, котора выполнена -выпуклой криволинейной , при этом на нижней поверхности балансира , по его концам, выполнены криволинейные выемки, в которых размещены головки упом нутых вертикальных подвесок.The goal is achieved by the fact that the spring suspension of a rail vehicle is equipped with a bracket rigidly mounted on the trolley frame, and between the longitudinal balance bar and the bracket, elastic elements and a movable support with a concave curvilinear surface interacting with the upper surface of the balance bar, which is made , while on the lower surface of the balancer, at its ends, curved grooves are made, in which the heads of the aforementioned vertical are placed GOVERNMENTAL suspensions.

Кроме того, криволинейные поверхности подвижной опоры и балансира выполнены цилиндрическими, а диаметры их св заныIn addition, the curvilinear surfaces of the movable support and the balancer are cylindrical, and their diameters are related

Claims

The device comprises a balancer 1, which, with its convex surface, interacts with the concave surface of the movable support 2, supported through elastic elements 1 of 3, on the bracket 4 rigidly fixed in the frame of the locomotive. In the balance bar 1, the movable support 2, the elastic elements 3 and the bracket 4 there are two through holes through which the suspensions 5 pass through, connected to the springs. The heads 6 of the suspensions 5 are made in the form of cylinders and are located in the grooves on the underside of the balance weight 1. The spring suspension works in a similar way. When changing the load on one of the wheelsets, HanptiMep when hitting the wheel on the rail joint, the spring of this wheelset changes the deflection arrow. This leads to an upward movement of the suspension 5, the balancer 1 rolls over the movable support 2 and causes the second suspension to move downward, and hence an increase in the deflection of the spring connected to it, which transfers the load to the corresponding wheel set. Thus, there is a redistribution of loads. The use of the proposed spring suspension reduces friction of the mating surfaces, thereby increasing the sensitivity of the suspension and, ultimately, improving the driving performance of the locomotive, especially at high speeds. In addition, the use of the invention greatly simplifies the design of the device, thereby reducing the laboriousness of its manufacture, ease of assembly and maintenance, and saving metal. Claim 1. Suspension suspension of a rail vehicle comprising leaf springs, supporting wheels for axle boxes, a longitudinal balancer, associated with a trolley frame with vertical parts, and vertical suspensions with heads connecting adjacent ends of leaf springs with balancer ends, differing the fact that in order to improve the driving performance of the vehicle, it is equipped with a bracket rigidly mounted on the bogie frame, and between the longitudinal balance bar and the bracket are placed successively elastic elements you and the movable support of the concave curved surface cooperating with the upper surface of the balancer, which is convexly curved, while the lower surface of the balance bar at its ends, made curvilinear recesses which accommodate the head of said vertical suspension,

2. The spring suspension according to claim 1, characterized in that the curvilinear surfaces of the movable support and balancer are cylindrical, and their diameters are related by: 1.2-1.5, -diameter of the concave surface under the sliding support; - diameter of the convex surface of the balancer; di is the diameter of the recess balancer; d - diameter of the suspension head.
