Title:
HAND BRAKE SYSTEM AND RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/027069
Kind Code:
A1
Abstract:
Embodiments of the present application provide a hand brake system and a railway vehicle. The system comprises a hand brake body, a tension averaging mechanism, a movable pulley mechanism, steel cables, and lever amplification mechanisms. A tension output end of the hand brake body is connected to a tension input end of the tension averaging mechanism; two tension output ends of the tension averaging mechanism are respectively correspondingly connected to two tension input ends of the movable pulley mechanism by means of the steel cables; two tension output ends of the movable pulley mechanism are respectively correspondingly connected to tension input ends of the two lever amplification mechanisms by means of the steel cables; and the lever amplification mechanisms are respectively provided on the corresponding basic brakes, and a tension output end of each lever amplification mechanism is connected to a brake rod of the corresponding basic brake. Use of the tension averaging mechanism realizes dual-axle application of braking force, and when the braking force of one axle is stuck, the braking force of the other axle can still be normally applied, thereby ensuring normal operation of the vehicle.
