The invention relates to the technical field of railway
vehicle braking, and discloses a basic braking device for a digital rail
train, which comprises a bracket, a
brake disc, a support frame and a pushing
assembly, the bracket is provided with a limiting groove for circumferentially limiting the
brake assembly, circumferential
friction force is directly transmitted to a
train body, and the support frame is prevented from being over-positioned due to
bending moment deflection; the supporting frame and the bracket are in sliding connection through the guide pin and the guide cylinder, two-stage sliding of the
brake assembly and the brake disc is achieved, the brake assembly can symmetrically clamp the brake disc and counteract
axial thrust step by step, and the brake stability is improved. Meanwhile, the guide cylinder is provided with the oil injection
nozzle and the detachable cylinder cover, the brake assembly can be rapidly disassembled and assembled without disassembling parts such as wheels, lubricating
grease is conveniently replaced, and the maintenance process is simplified.
