Abstract

The invention belongs to the field of retarders, and specifically relates to a freight train self-storage energy retarder. The problem that energy released during deceleration of an existing train isnot recovered is aimed at. The invention discloses the freight train self-storage energy retarder. The technical scheme is that the freight train self-storage energy retarder comprises a top (1), a top seat (4), and a fixing device and further comprises a ball screw (2) and a power generating and storing device, the ball screw (2) is provided with a nut (5) in a matching mode, the top (1) is fixedly connected with the nut (5), a spring (7) sleeves the ball screw (2), the spring (7) is located between the nut (5) and the fixing device, the power generating and storing device comprises a generator (23) and an energy storage device, the fixing device and the top seat (4) are connected, the lower end of the ball screw (2) is rotatably connected with the fixing device, and the lower end of theball screw (2) is connected with a rotating shaft of the generator (23). The freight train self-storage energy retarder is suitable for decelerating trains.

Description

technical field [0001] The invention belongs to the field of deceleration tops, in particular to a self-storage energy deceleration top for freight trains. Background technique [0002] The deceleration top is a kind of internal hydraulic oil, installed on the inner or outer side of the rail, through the contact of the sliding cylinder and the wheel, the internal hydraulic oil is squeezed to perform braking work on the vehicle wheel to play a role in deceleration A speed control device. Its working principle is: [0003] When the vehicle passes through the decelerator, its wheel set travel speed is lower than the critical speed set by the decelerator. At this time, there will be no large pressure difference between the upper and lower chambers of the sliding cylinder, and the speed valve will be kept open. state, the oil in the upper chamber of the sliding cylinder will flow to the lower chamber through the passage of the speed valve, because the upper chamber of the slidi...
