Abstract

The invention provides a brake disc and a vehicle provided with the same. The brake disc comprises a disc body, a disc hub and disc hub force-transferring keys, wherein a plurality of connecting clawsare arranged on an inner ring of the disc body and arranged in the circumferential direction of the inner ring at intervals, and a disc body force-transferring groove is formed between the at least two adjacent connecting claws; the disc hub is connected with the disc body and is provided with at least one disc hub force-transferring key mounting hole, and the disc hub force-transferring key mounting holes correspond to the disc body force-transferring grooves; and the first ends of the disc hub force-transferring keys are arranged in the disc body force-transferring grooves in a penetratingmode, and the second ends of the disc hub force-transferring keys are arranged in the disc hub force-transferring key mounting holes in a penetrating mode. The brake disc solves the problem that a disc body and disc hub positioning structure of a brake disc in the prior art is complex.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a brake disc and a vehicle with the same. Background technique [0002] With the rapid development of rail transit, disc brakes are more and more used in the basic braking of rail transit vehicles because of their advantages such as stable friction performance, large energy absorption, good heat dissipation performance and little damage to the tread compared with tread brakes. device. [0003] As an important part of the disc-shaped basic braking device, the brake disc presses the friction surface of the brake disc through the brake pads during the train braking process to achieve train braking, thereby ensuring the safe and stable operation of the train. It plays an important role in safe and reliable operation. [0004] During the braking process, the brake disc bears the braking torque applied by the brake pads, and the brake disc connector bears the braking torque transmitted from t...
