Choose, float, inlay pieces of type rub from equal to the brakes as the design plan relatively. use function design principle confirm from the design starting point of applying the brake jointly, i.e. design the clutch from the viewpoint of moment, calculate and transmit the torsion; Design the brake from the viewpoint of energy, calculate and make the square of motive force. Choose to rub lumps and manufactured materials and assign the form, confirm the main size of the piston, cylinder and tray, then design the systematic ensemble architecture, through checking and according with the designing requirement, thus solved a great deal of problems that the system is designed and calculated and the structure is fixed completely. through analyzing, this system can realize the function before applying the brake jointly about the theory that is designed. Have to be of simple
