Hand braking transmission system of railway vehicle

Abstract

The invention discloses a handle braking transmission system of a railway vehicle. The handle braking transmission system comprises a hand braking shifter lever, a draw rod, a first hand braking connection rod and a second hand braking connection rod, wherein one end of the draw rod is pivoted with the hand braking shifter lever, one ends of the first hand braking connection rod and the second hand braking connection rod are pivoted, the other end of the first hand braking connection rod is pivoted with the lower end of the hand braking shifter lever through a first pin shaft, and the other end of the second hand braking connection rod is pivoted with the upper end of a braking lever through a second pin shaft. The novel handle braking transmission system is designed for the railway vehicle which uses integration braking, hand braking chains in prior art are replaced by the first hand braking connection rod and the second hand braking connection rod, so that problem that chains sag to interfere axles during air braking actions is solved, hidden dangers influencing traffic safety are removed, and normal operation of vehicles is guaranteed.

Description

technical field [0001] The invention relates to a railway vehicle brake technology, in particular to a railway vehicle hand brake transmission system. Background technique [0002] The braking system of railway vehicles includes air braking system and hand braking system. The air brake is used to provide braking force when the vehicle is running on the road, and the hand brake is used to provide braking force when the vehicle is overhauled and organized. When the hand brake is in effect, operate the hand brake and amplify the force generated by the hand brake by a certain multiple through the hand brake transmission system, transmit it to the bogie, and form the braking force through the braking system of the bogie. [0003] In order to improve the braking efficiency, the braking system of the bogie often adopts integrated braking, also known as unit braking. The braking system is composed of components such as brake cylinder, brake lever and brake shoe clearance adjuster....
