Large Gauge Magnetic Rail Brake Suspension Device for Rail Vehicles

Abstract

The invention relates to a suspension device for a large-gauge magnetic rail brake of a rail vehicle, which is installed between the magnetic rail brakes on both sides and the vehicle bogie. The suspension device includes a cylinder component, a connecting plate and a positioning component. The cylinder component is installed on each The front and rear ends of the upper surface of the side magnetic rail brake, the upper end of the cylinder is connected to the vehicle bogie, the cylinder consists of a cylinder body and an adapter assembly, the adapter assembly is installed at the upper and lower ends of the cylinder body, and the cylinder body is a single-acting spring cylinder. The transfer assembly is equipped with a matching structure of arc surface and curved surface; the connecting plate is installed horizontally between the magnetic track brakes arranged oppositely on both sides of the vehicle bogie, connecting the magnetic track brakes on both sides as a whole, and the upper and lower ends of the positioning composition are respectively connected with the connecting The plate is fixedly connected to the bottom surface of the vehicle bogie. It can ensure a large gap between the magnetic track brake and the track, and can quickly and reliably apply the magnetic track braking force to reduce the braking force loss rate.

Description

technical field [0001] The invention relates to the technical field of rail vehicle braking, in particular to a suspension device for a large-gauge magnetic rail brake of a rail vehicle. Background technique [0002] The magnetic rail brake is a key component that provides the emergency braking force of rail transit vehicles. When the magnetic rail brake receives the braking command, it energizes the excitation coil, and the pole shoe induces electromagnetic force to attract the magnetic rail brake to the rail surface, relying on the contact between the pole shoe and the rail The friction between them provides the braking force. [0003] The magnetic rail brake is connected with the vehicle bogie by means of the suspension device. When the brake is not applied, the suspension device ensures a certain distance between the pole piece and the rail surface to prevent collision or friction between the magnetic rail brake and the rail during normal operation of the vehicle; When ...

Problems solved by technology

That is, the existing suspension device is mainly used to realize dustproof and anti-loosening, and cannot be applied to the suspension of large-gauge magnetic rail brakes, and because the existing suspension device adopts the suspension spring method, when the brake is applied, the electromagnetic attraction force of the magnetic rail brake It is necessary to overcome the spring compression force and absorb on the surface of the rail. The electromagnetic attraction force of the electromagnetic brake cannot be completely converted into braking force, and the conversion efficiency of braking force is low.
