Abstract

The invention discloses a hump vehicle reducer with permanent magnet excitation, which belongs to the technical field of railway speed regulation. The hump vehicle speed reducer includes a brake part and a cylinder part. The brake part includes a friction plate, a cover plate and a return spring; the cylinder part includes a top cover, a permanent magnet group, a magnetic isolation plate, a base and a connector, and the permanent magnet assembly includes an upper armature, a permanent magnet and a lower armature. The hump vehicle reducer generates braking through the magnetic force of permanent magnets, including eddy current braking and friction braking. It uses the cylinder to realize the on-off of the magnetic circuit, and then controls the working state. It has a simple structure and simple operation. The hump vehicle speed reducer of the present invention combines eddy current braking with traditional mechanical braking, and has the advantages of simple structure, higher safety factor, longer service life, energy saving and better braking effect.

Description

technical field

[0001] The invention belongs to the technical field of railway speed regulation, in particular to a hump vehicle reducer with permanent magnet excitation. Background technique

[0002] As of the end of 2018, the total mileage of my country's railways has reached 131,000 kilometers, of which 29,000 kilometers are high-speed railways, accounting for 2 / 3 of the world's total mileage. Among them, the number of freight trains has also increased sharply, and the pressure on railway freight has increased sharply. The marshalling and scheduling efficiency of stations has become an increasingly important issue. The marshalling yard is the basic unit of railway operation. Its main job is to reorganize the traffic flow, that is, to dismantle and reprogram various freight trains in large numbers and quickly. Among them, the hump is the most important shunting equipment in the marshalling yard. The efficiency of the hump dismantling operation directly affects the turnarou...
