Technical Field

[0001] The present invention relates to the technical field of dual-motor time-sharing synchronous clutch, in particular to a mechanical disc brake clutch. Background Art

[0002] The existing dual motor connection is controlled by electronic control parameters such as sensors and encoders to achieve single-machine operation and dual-machine synchronization, which is complex in structure and high in cost. However, due to the differences in motor and control accuracy, as well as the sensitive interference of loads and road conditions on electricity, the dual motor synchronization cannot be effectively controlled. The centrifugal connection device, because of the centrifugal radial force, will produce instability and vibration during the start-up and switching. To address these defects, it is necessary for us to design a mechanical disc brake clutch. Summary of the invention

[0006] The beneficial effects of the present invention are as follows: the cam and the end of the connecting shaft are respectively connected to the auxiliary motor and the main motor. When the main motor is running, the friction plate is in a separated state through the return springs on both sides and does not contact other parts. The output shaft drives the friction plate to rotate together. When the auxiliary motor and the main motor need to be synchronized, the auxiliary motor is started to rotate and the cam is driven to convert the circumferential radial force of the motor rotation into axial thrust through the curved roller cover plate to press the friction plate forward against the curved roller cover plate, and the two motors are coupled into one through friction.
