Problems solved by technology

[0010] The purpose of the present invention is to propose a new method to improve the lateral displacement quality of the vehicle and reduce the gap between the car body and the bogie, aiming at the lack of uneven transverse shear force in the elastic vibration-absorbing load-carrying element between the existing car body and the bogie. The method and lateral displacement system for elastic vibration-damping load-bearing elements to resist the uneven stress caused by lateral displacement; this new method for improving the quality of lateral displacement and lateral displacement system can effectively solve the problem of elastic vibration damping between the car body and the bogie The problem of uneven lateral displacement stress of load-bearing elements, thereby improving the quality of lateral displacement of the vehicle

Embodiment 1

[0037] After research and analysis, the inventor found that the reason why the vehicle tends to be unstable when moving laterally is mainly due to the instability of the elastic damping load-bearing element arranged between the car body and the bogie, and the elastic damping load-bearing element The instability of the vehicle is mainly due to the large transverse shear force generated on the elastic vibration-absorbing bearing element when the vehicle moves laterally, which makes the internal stress uneven and easy to lose stability, which we have not considered before; in fact , the elastic vibration-damping bearing elements are placed on the bogie (as attached figure 1 As shown), it not only bears the weight of the car body, but also provides horizontal displacement for the locomotive when it moves. For example, when the car body passes a curve, the horizontal movement of the car body and the bogie is provided by the elastic vibration-absorbing bearing element. In addition, t...

Embodiment 2

[0062] The principle of embodiment two is the same as that of embodiment one, but the combination structure is slightly different. figure 2 It can be seen that the present invention relates to a lateral displacement system for improving the lateral displacement quality of rail vehicles. The lateral displacement system includes a car body, a center disc, a bogie and an elastic damping bearing element, and the car body is installed on the bogie through the center disc. Between the car body and the bogie, there are a plurality of elastic damping bearing elements arranged around the central pin of the center plate, and the elastic damping of the car body is realized through the elastic damping bearing elements; the elastic damping bearing elements are horizontal, etc. Strain elastic damping bearing element, when the elastic damping bearing element is laterally displaced by the rail vehicle, the lateral displacement between the car body and the bogie is damped through the lateral e...

Embodiment 3

[0065] The principle of the third embodiment is the same as that of the first embodiment, but the combined structure is slightly different, and the attached Figure 8 It can be seen that the present invention relates to a lateral displacement system for improving the lateral displacement quality of rail vehicles. The lateral displacement system includes a car body, a center disc, a bogie and an elastic damping bearing element, and the car body is installed on the bogie through the center disc. Between the car body and the bogie, there are a plurality of elastic damping bearing elements arranged around the central pin of the center plate, and the elastic damping of the car body is realized through the elastic damping bearing elements; the elastic damping bearing elements are horizontal, etc. Strain elastic damping bearing element, when the elastic damping bearing element is laterally displaced by the rail vehicle, the lateral displacement between the car body and the bogie is da...

Abstract

The invention discloses a method for improving the transverse displacement quality of a railway vehicle and a transverse displacement system. A transverse equal-strain elastic vibration reduction bearing element is arranged between a bogie and a vehicle body of the railway vehicle; and when the transverse displacement of the rail vehicle occurs, the transverse equal stress deformation of the transverse equal-strain elastic vibration reduction bearing element ensures that the vehicle is always in a stable transverse displacement state during the transverse displacement, so that the transverse displacement quality of the vehicle is improved. The transverse equal-strain elastic vibration reduction bearing element is arranged between the bogie and the vehicle body, the stability of transverse displacement of the vehicle is ensured through equal-strain deformation of the elastic vibration reduction bearing element, instability caused by uneven transverse strain of the elastic vibration reduction bearing element is avoided, the damage of the elastic vibration reduction bearing element caused by stress concentration is avoided, and the comprehensive performance of the elastic vibration reduction bearing element is improved.

Description

technical field [0001] The invention relates to a method for lateral displacement of a rail vehicle and a lateral displacement system thereof, in particular to a method for improving the quality of lateral displacement of a rail vehicle and a lateral displacement system. The method for improving the quality of lateral displacement of a rail vehicle and the lateral displacement system pass through The form of lateral equal stress improves the quality of lateral displacement of rail vehicles. Background technique [0002] For rail vehicles, it usually includes a car body and a bogie, and the car body is installed on the bogie through a connection system, so that the steering of the car body can be effectively realized when the vehicle turns; at the same time, in order to ensure the vibration reduction effect of the vehicle and Elastic damping bearing elements will be installed between the car body and the bogie to eliminate the impact of the traveling system under the bogie on...
