The invention discloses a combined braking device, a railway vehicle and a method, solves the problem that vacuum braking and air braking are unreasonable in structural arrangement in the prior art, and has the beneficial effects that the structural arrangement is reasonable, and independence of vacuum braking and air braking can be guaranteed. Comprising an air brake cylinder, the air brake cylinder comprises a first cylinder body, the first cylinder body is provided with a first piston piece, the first piston piece is hollow, a push rod is slidably installed in the hollow position of the first piston piece and connected with the input end of a brake lever, and the output end of the brake lever is connected with a vehicle brake device. The first piston piece drives the push rod to push the brake lever, and the output end of the brake lever pulls the vehicle brake device to achieve air brake. The vacuum brake cylinder comprises a second cylinder body, the second cylinder body is provided with a second piston part, the second piston part is connected with the transmission shaft assembly, and the push rod is connected with the transmission shaft assembly through a flexible structural part.
