Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A motor disc brake assembly as shown in fig. 1-4, including brake disc 2, brake wheel 3 and motor shaft sleeve 1, the cross-section of this motor shaft sleeve 1 is T type structure, this motor shaft sleeve 1 side is equipped with fluting 5, this fluting 5 runs through this motor shaft sleeve 1 side and extends to motor shaft sleeve 1's prelude and afterbody respectively, brake disc 2 middle part is equipped with the centre bore that is used for motor shaft sleeve 1 to pass, brake disc 2 middle part is equipped with the round hole along this centre bore annular array distribution, the circumference of this brake disc extends limit department and is equipped with round edge 4 that is used for the stopper to stop, this brake wheel 3 sets up the below of brake disc 2, the prelude surface of brake wheel 3 and the bottom surface butt of brake disc 2, the surface of brake wheel 3 is equipped with the matrix and is equipped with a plurality of bolt hole, this motor shaft sleeve 1 run-through setting is in brake disc 2 and brake wheel 3's inside.

The middle part of the motor shaft sleeve 1 is also provided with a through hole for the motor shaft to pass through in a penetrating way. The head part of the motor shaft sleeve 1 is distributed with bolt holes corresponding to the brake wheels 3 in a rectangular array manner. The surface of the brake wheel 3 is provided with a shaft sleeve hole, and a plurality of round holes corresponding to the brake disc 2 are arranged in an annular array mode along the central shaft of the shaft sleeve hole. The material of the brake disc 2 is heat-resistant steel, and the thickness of the round edge 4 is between 5 mm and 8 mm.
