Abstract

An electric locomotive brake device mainly solves the technical problems that a hand wheel mechanical brake device adopted by an existing locomotive is cumbersome, low in response speed, inconvenientfor a driver and an operator to operate and the like. The device is characterized by comprising a hand wheel rotating threaded lead screw, a cross arm, a brake connecting rod, a brake shoe, a foot valve, a steel wire rope, a hydraulic master cylinder and a hydraulic connecting rod, the hand wheel rotating threaded lead screw is connected with the cross arm, the cross arm is connected with the brake shoe through the brake connecting rod, and the foot valve is connected with the hydraulic connecting rod through the steel wire rope. The brake device is mainly applied to industrial and mining electric locomotives.

Description

technical field [0001] The invention relates to a brake device for an electric locomotive. Background technique [0002] At present, the brake devices of industrial and mining electric locomotives mostly use hand wheel mechanical brake devices, which have problems such as heavy hand wheel mechanical brake devices, slow response speed, and inconvenient operation for drivers and operators. Contents of the invention [0003] The purpose of the present invention is to provide a brake device for electric locomotives that is bulky, slow in response, and inconvenient for drivers and operators to effectively improve the driving pleasure of the drivers for electric locomotives. [0004] The technical solution adopted by the present invention to solve its technical problems is: comprising hand wheel rotating threaded screw, cross arm, brake connecting rod, brake shoe, pedal valve, steel wire rope, hydraulic master cylinder and hydraulic connecting rod, said The threaded screw rod r...
