  • Patent number: 5862685
    Abstract: A washing machine transmission performs a washing by rotating a pulsator in forward and reverse directions during a washing cycle even though a driving source rotates in any one direction only, so that an overload in the driving source can be prevented. A first link is attached to an upper end of a driving shaft, and has a first guide pin. A second link is hinged to an inner peripheral surface of a brake drum at a first end and has a second guide pin, and has a first oblong slot formed between the first end and the second end. A third link is attached to a driven shaft, and has a second oblong slot. When the driving shaft rotates, the first guide pin rotates.
