When the brake caliper is used, in the first step, as shown in fig. 1-5, the two hydraulic calipers work simultaneously during braking, so that the friction plates 405 on the two sides are pushed by the piston to move towards the middle part synchronously, the brake plates 404 on the two sides push the brake plates 404 and 405 in the middle part to be concentrated towards the middle part when moving towards the middle part, in the process, the guide blocks 409 at the two ends of the friction plate 405 move towards the middle part along the guide grooves 408 in the middle part of the brake caliper 403, and the clamping grooves 407 on the brake plates 404 slide towards the middle part along the clamping blocks 406; the brake caliper 403 continues to push the friction plates 405 on the two sides to move towards the middle, so that the brake plate 404 and the friction plates 405 are clamped together, friction is generated between the brake plate 404 and the friction plates 405 under the action of pressure, the friction plates 405 can only horizontally move and cannot rotate because the guide blocks 409 at the two ends of the friction plates 405 are clamped in the guide grooves 408 of the brake caliper 403, and the brake plate 404 is installed on the clamping blocks 406 of the brake sleeve 401 through the clamping grooves 407, so that the brake plate can only slide left and right along the brake sleeve 401 and cannot relatively rotate; therefore, under the action of the friction plate 405 and the brake plate 404, a certain resistance is provided for the brake plate 404, and the brake sleeve 401 is braked under the action of the resistance of the brake plate 404, so that the brake of the hub 3 is realized, the brake resistance is equal to the sum of the friction force between the brake plate 404 and the friction plate 405, the friction force between each brake plate 404 and the friction plate 405 can provide brake force, and the brake effect is good; in summary, with the design of the split disc type multi-abrasive disc brake device 4, during braking, the brake caliper 403 pushes the friction discs 405 on the two sides towards the middle, so that the friction discs 405 and the brake disc 404 are attached together, the friction force between each brake disc 404 and the friction disc 405 can provide braking force, the braking area is increased, the braking effect is greatly enhanced, and the problems that the disc brake realizes the braking process by tightening the brake caliper, the attaching of the braking area is small, and the braking effect is poor are solved; during braking, the whole braking force is shared between the multiple friction plates 405 and the brake plate 404, and the acting force between the friction plates 405 and the brake plate 404 is small, so that the effect of single-body light-weight braking is achieved.
