The invention discloses a brake cylinder for a rail transit vehicle. The brake cylinder comprises a pushing component and a piston. The piston drives the pushing component to brake the rail transit vehicle. In addition, the brake cylinder further comprises a push rod capable of being driven by the piston, and the pushing component comprises a thrust fulcrum. In addition, the thrust fulcrum is in sliding contact with the push rod so as to transmit braking force. According to the braking air cylinder for the rail transit vehicle, braking force needed by the braking air cylinder is effectively amplified, meanwhile, waste of the braking force in the idle stroke is reduced, the overall braking effect is improved, and the stability and safety of the rail vehicle in the braking process are guaranteed. Meanwhile, the brake cylinder can further reduce the space required by the brake device and reduce the weight of the brake device. And the number of parts of the braking device is reduced while the requirement for braking force is met, so that the braking device is easier to mount and dismount, and the overall working efficiency is improved.
