A dual-directions braking method of a disc brake, a braking mechanism and applications thereof are applied in fields of automobiles, trains and aircrafts. The dual-directions braking mechanism includes a crankshaft having three concentric sections and two eccentric sections, two friction discs, a friction disc ring and at least a pair of brake calipers and friction pads, wherein the two eccentric sections are respectively provided between each neighboring two of the three concentric sections and mutually disposed at 180°; the two friction discs are respectively provided on the two eccentric sections; the friction disc ring is provided on the main section between the two eccentric sections. Through a translationally rotating friction by the two friction discs respectively with the friction disc ring and with the friction pads of each pair of brake calipers, a backward braking moment and a forward braking moment are simultaneously generated on the main sections, so as to enhance a braking performance twice while keeping a wheel friction load unchanged, compared to conventional backward brakes. An automobile dual-directions braking system including the dual-direction braking mechanism is able to accomplish electronic safety control functions of DABS, DEBD and DESP, and greatly improve transportation safety. |
