Abstract

The invention provides a brake system for an underground diesel locomotive. The brake system comprises a travelling braking branch circuit comprising a flow control unit and a brake air cylinder whichare connected in series on an air course; the flow control unit controls the air mass flow flowing into the brake air cylinder according to the magnitude of a current signal of a brake handle of theunderground diesel locomotive; the brake air cylinder comprises a first cylinder body, and the first cylinder body comprises a left chamber and a right chamber which are partitioned by a first piston;and the left chamber of the first cylinder body in internally provided with a first spring capable of making the first piston to be reset, the left end of the first piston is provided with a piston rod, the tail end of the piston rod of the first piston extends out of the first cylinder body and is connected to a brake executing mechanism, and air coming from the flow control unit enters the leftchamber of the first cylinder body. According to the brake system for the underground diesel locomotive, pilot control is adopted, the response time is short, and brake braking can be conducted safely and effectively; and it is further ensured that an operator can obtain required brake force by controlling the stroke of the brake handle according to the actual need.

Description

technical field [0001] The invention relates to a brake system of an underground diesel locomotive. Background technique [0002] The braking system of the existing underground diesel locomotive cannot control the braking force according to the stroke of the brake handle, and the corresponding time of the braking system is long, and the safety is not high. Contents of the invention [0003] The object of the present invention is to provide a safe and efficient braking system for underground diesel locomotives that can provide controllable braking force. [0004] In the following, the terms "left" and "right" refer to the attached figure 1 The shown left and right, that is, the left-hand side and the right-hand side of the reader when looking at the picture, do not limit the direction in actual use. [0005] The braking system of an underground diesel locomotive according to the present invention includes a service braking branch, and the service braking branch includes a...
