Abstract

The invention relates to the technical field of railway construction, and discloses a decelerator for use on a train utilizing electrorheological fluid. When the train speed is too high, the faster the train wheels rotate, the larger the generated current is, and according to the principle of the electrorheological fluid, the medium in the medium rotating shaft is changed into solid from originalliquid, the friction force on the train wheels is increased, and the rotating speed is gradually reduced. The device is installed on a train wheel through a magnetic inductor. The medium bearing is movably mounted on a train wheel; a decelerating shaft is connected to a central shaft of a train wheel, the decelerating shaft is connected with a rotating shaft through a bearing shaft, the rotating speed is kept consistent, the faster the rotating shaft rotates, the faster the conductor is driven to cut magnetic induction lines, the larger the current generated in a coil is, and a medium is converted into solid from liquid to generate friction force on the decelerating shaft. The automatic decelerating process is thus achieved. When the speed of the train is reduced to a controllable value, the running safety performance of the train is improved, and the life of a passenger and the life of a driver can be ensured.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to a speed reducer for trains using electromorphic variants. Background technique [0002] The train is favored by the public because of its cheap freight. However, due to the high mass of the train and the large inertia generated during the driving process, accidents caused by natural causes are excluded. Most of the accidents caused by train derailment due to excessive speed are caused by trains that are too fast. The potential safety hazard is huge, and the speed is too fast. When an emergency occurs, the vehicle itself is too heavy and cannot be stopped in time after emergency braking, which may cause derailment and seriously threaten the lives of passengers and drivers. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a reducer for trains using current variants, ...
