The invention discloses a novel full-linear clutch. The novel full-linear clutch comprises a shell, a belt pulley, a bearing, an upper cover, a shaft connecting bearing, a spindle, a water seal, a wire, a coil slot, a coil, an armature, an elastic piece, an elastic piece seat, a magnetofluid holding chamber and a PWM pulse signal generator. According to the novel full-linear clutch, functions and performance of an existing clutch can be changed effectively, thereby meeting usage needs, and the advantage of high response speed of an electromagnetic clutch is also achieved. The defects that the electromagnetic clutch only has the switching characteristic but does not have the intermediate characteristic are overcome, the advantage that a silicone oil clutch flexibly transmits torque is also achieved, and the defect that intermediate torque cannot be controlled is overcome.
